    Plaintiff and appellant Chad Defries suffered injuries while riding a Yamaha dirt

    caused by a throttle assembly that fell off the handlebar as he was riding. The jury found
    in Yamaha’s favor, and the trial court later awarded Yamaha costs.
    On appeal, Defries contends, among other things, that the court erroneously denied
    his request to instruct the jury that Yamaha was liable for its dealer’s negligent assembly
    of the dirt bike, a ruling that limited Defries’s negligence cause of action to Yamaha’s
    own negligence. California law, however, places “responsibility for defects, whether
    negligently or nonnegligently caused, on the manufacturer of the completed product . . .
    regardless of what part of the manufacturing process the manufacturer chooses to
    delegate to third parties.” (Vandermark v. Ford Motor Co. (1964) 
    61 Cal.2d 256
    , 261
    (Vandermark).) The same principle applies to distributors. And as the distributor of a
    completed product, Yamaha “cannot delegate its duty . . . [and thus] cannot escape
    liability on the ground that the defect in [Defries’s bike] may have been caused by
    something one of its authorized dealers did or failed to do.” (Ibid.) Thus, Defries was
    “relieved of proving that the manufacturer or distributor was negligent in the production,
    design, or dissemination of the [product].” (Daly v. General Motors Corp. (1978) 
    20 Cal.3d 725
    , 736-737.) Rather, if the dealer negligently assembled the product, Yamaha
    was jointly liable for damages caused by that negligence. Because the requested
    instruction should have been given, we reverse the judgment on the negligence cause of
    action. We otherwise affirm the judgment.

    I. BACKGROUND
    Defries’s wife purchased a dirt bike in December 2016 as a Christmas present for
    her husband. Defries first rode the bike a month later.
    On February 12, 2017, Defries rode the dirt bike again. He met with his friends
    Johnny Butcher and Johnny Kitchin at a dirt course in Perris.
    Defries rode for about 15 or 20 minutes and was going through the whoops, or
    small hills, portion of the course. As he testified at trial: “I was coming through [the
    whoops] kind of in a crouched position, sitting up over the bike. As I’m going the bike is
    rocking back and forth. And then at one moment the throttle just kind of slipped off and
    the handlebars came into me and I went down. It was quick. It just happened like that.”
    Butcher testified at trial that “[j]ust shortly after [Defries] entered the whoops,
    maybe the second or third one in, his handlebars went to the left and then he just
    tumbled.” Both Butcher and Kitchin observed that the throttle was hanging off to the
    side and not attached to the bike when they loaded the bike back onto Defries’s truck
    after the accident.
    Defries fractured his right femur and separated his shoulder. He possibly suffered
    a hernia from the accident as well.
    Defries filed suit against four defendants: Yamaha, Yamaha Motor Company
    Limited (Yamaha Japan), Yamaha Motor Manufacturing Corporation of America, and
    West Coast Yamaha, Inc., doing business as Langston Motorsports (Langston
    Motorsports). The complaint alleged five causes of action against all defendants:
    3
    negligence, strict product liability (manufacturing defect), strict product liability (design
    defect), strict product liability (failure to warn), and breach of implied warranty.
    Yamaha Japan and Yamaha Motor Manufacturing Corporation of America were
    dismissed early, leaving only Yamaha and Langston Motorsports as defendants. Defries
    settled with Langston Motorsports before opening statements began at trial. During trial,
    Defries withdrew his causes of action for strict products liability (manufacturing defect)
    and strict products liability (design defect). Thus, the jury was tasked with determining
    only whether Yamaha was liable for three causes of action: negligence, strict products
    liability (failure to warn), and breach of implied warranty.
    Within the complaint’s negligence cause of action, Defries alleged that Yamaha
    (and the other defendants) had a duty to assemble the motorcycle so that the throttle
    assembly did not disengage from the handlebar, and that they negligently assembled it.
    Prior to trial, Defries opposed summary judgment by arguing, as its first reason why
    Yamaha was negligent and citing Vandermark, that Yamaha was liable for the dealer’s
    negligence in failing to properly secure the throttle because it had a nondelegable duty to
    properly assemble his motorcycle.
    Defries’s trial theory was that the crash was caused by the failure of one or both of
    the bolts in the throttle assembly to be properly tightened, and that Yamaha was liable
    even though it did not assemble the throttle. In opening statements, Defries’s counsel
    told the jury that Yamaha has “what we call a nondelegatory duty” to make sure the
    4
    motorcycle is safe, but they chose to delegate that responsibility to the dealer and “the
    throttle bolts were not properly secured at the dealership.”
    A Yamaha employee testified that its dirt bikes are designed by Yamaha Japan and
    that Yamaha distributes those dirt bikes in the United States. Yamaha buys the dirt bikes
    from Yamaha Japan but does not assemble them; rather, it passes along partially
    assembled dirt bikes from Yamaha Japan in crates to dealers, who then complete final
    assembly of the dirt bikes before selling them to consumers. The dealer’s assembly
    includes putting the throttle assembly onto the handlebar and assembling the handlebar
    onto the dirt bike. Langston Motorsports was the dealer who assembled and sold
    Defries’s dirt bike.
    One of Defries’s experts, Russell Darnell, opined that Langston Motorsports did
    not properly torque the bolts on the throttle assembly—that “[m]ost likely” the Langston
    Motorsports employee in charge of assembling the dirt bike “tightened one too tight and
    the second one not to spec.” Darnell stated that when a bolt is not properly tightened,
    vibrations from vehicle operation can cause it to fall out. He stated: “[P]ractically
    everybody has got a weed eater or an old car or something where a bolt falls out. That’s
    from vibration. A bolt never tightens itself. It will always continue to the outside to
    where it gets to the point where it falls out. That’s just normal vibration. In this case the
    bolts were not torqued to enough torque to stop that.” Darnell stated that bolt release
    could occur either if “[t]he bolts were not tightened enough” or if the one of the bolts
    were over-torqued. Darnell opined that had the bolt been properly tightened, Defries
    5
    would not have crashed the dirt bike. Separately, Darnell stated that the throttle cable on
    Defries’s dirt bike (which was shown at trial) had been routed to the handlebar
    incorrectly. Another of Defries’s expert witnesses, Christopher Brignola, also testified
    that one of the assembly bolts attaching the throttle to the handlebar had been
    overtightened.
    Yamaha disputed that the throttle bolts had been improperly tightened. As one of
    its experts stated: “When the bolts are loose, the throttle can rotate on the handlebar. In
    order to give it gas, it has to be—if you twist it—the effect is that you can’t give it
    consistent amounts of throttle. It slips on the handlebar. It affects your ability to control
    that. You’re not able to start it up.” Another one of its experts conceded that the throttle
    cable had been routed incorrectly. Yamaha contended that a throttle cable leashes the
    assembly to the handlebar and that the amount of force that would have been necessary to
    fully remove the assembly would have stretched and damaged the cable, adding that there
    was no such damage to the throttle cable on Defries’s dirt bike. Yamaha’s theory was
    that Butcher and Kitchin deliberately removed the throttle from the handlebar after the
    crash in order to “help” Defries. In response, Defries’ expert witness Brignola opined
    that there was “no evidence consistent with tampering of the bolts or disassembling of the
    throttle.”
    The jury returned special verdicts for Yamaha on all three causes of action, and
    the trial court entered judgment for Yamaha. The trial court later denied Defries’s new
    6
    trial motion and awarded Yamaha costs. Defries appealed from the denial of the motion
    for new trial and the motion to strike or tax costs that led to Yamaha’s costs award.
    II. DISCUSSION
    Defries correctly contends that the jury should have been instructed that any
    negligence in assembly by Langston Motorsports should be imputed to Yamaha because
    of a nondelegable duty Yamaha had, and that judgment on this claim must therefore be
    reversed.
    A. Instructional Error
    After the evidentiary phase of the trial had concluded but before closing
    arguments, in a hearing outside the presence of the jury, the trial court heard arguments
    over disputed jury instructions.
    Defries first requested, and the trial court refused, several instructions relating to
    the existence or nonexistence of an agency relationship between Yamaha and Langston
    Motorsports. The trial court believed that no evidence justified giving the instructions, at
    one point stating: “I have heard no evidence that they are your agent for general
    negligence.”
    Defries then requested that the jury hear CACI 3713, an instruction on
    1
    nondelegable duty. Defries argued that “it’s a matter of law that the manufacturer,
    1
    CACI 3713 reads as follows:
    “[Name of defendant] has a duty that cannot be delegated to another person arising
    from [insert name, popular name, or number of regulation, statute, or ordinance/a
    7
    distributor of a product has a nondelegable duty to provide a safe product to the
    consumer.” After the trial court noted that Defries had withdrawn some of his strict
    liability causes of action, Defries replied that Yamaha has “a nondelegable duty to make
    sure the product is consumer safe and that includes assembly. We have argued
    negligence [in] assembly in this case. That’s in fact one of our causes of action. The
    responsibility exists in that context as well.”
    The trial court concluded: “I don’t think this instruction is appropriate. I think it
    would be highly misleading and lead the jury to wrongly conclude that as a matter of law
    if they find negligence, that Yamaha is responsible. I don’t think we want to misdirect
    them.”
    Later, during closing arguments, Yamaha told the jury: “Let’s first talk about the
    negligence claim. There you see the first question, was Yamaha . . . negligent. That’s
    contract between the parties/other, e.g., the landlord-tenant relationship]. Under this
    duty, [insert requirements of regulation, statute, or ordinance or otherwise describe
    duty].
    “[Name of plaintiff] claims that [he/she/nonbinary pronoun] was harmed by the
    conduct of [name of independent contractor] and that [name of defendant] is responsible
    for this harm. To establish this claim, [name of plaintiff] must prove all of the following:
    “1. That [name of defendant] hired [name of independent contractor] to [describe
    job involving nondelegable duty, e.g., repair the roof];
    “2. That [name of independent contractor] [specify wrongful conduct in breach of
    duty, e.g., did not comply with this law];
    “3. That [name of plaintiff] was harmed; and
    “4. That [name of independent contractor]’s conduct was a substantial factor in
    causing [name of plaintiff]’s harm.”
    8
    where you have to see if they were negligent. You’re not deciding . . . Langston
    [Motorsports] or [the employee who assembled the dirt bike]. Your question you have to
    answer is was Yamaha negligent here. Yamaha should have given this warning to
    double-check the tightness of the bolts.”
    Yamaha continued: “When deciding the issue of negligence it’s not looking at,
    did the dealership screw something up and do something wrong here. It’s, did Yamaha
    do something wrong in the instructions or warnings that they gave to the dealership.”
    “An order denying a motion for new trial is nonappealable. [Citation.] Such an
    order, however, may be reviewed on appeal from the underlying judgment.” (Walker v.
    Los Angeles County Metropolitan Transportation Authority (2005) 
    35 Cal.4th 15
    , 18.)
    “[A] trial judge is accorded a wide discretion in ruling on a motion for new trial,”
    and “the exercise of this discretion is given great deference on appeal.” (City of Los
    Angeles v. Decker (1977) 
    18 Cal.3d 860
    , 871-872.) “We will not disturb the trial court’s
    determination of a motion for a new trial unless the court has abused its discretion.”
    (ABF Capital Corp. v. Berglass (2005) 
    130 Cal.App.4th 825
    , 832.) However, when the
    court has denied a motion for new trial, “we must determine whether the court abused its
    discretion by examining the entire record and making an independent assessment of
    whether there were grounds for granting the motion.” (Ibid.)
    “A party is entitled upon request to correct, nonargumentative instructions on
    every theory of the case advanced by him which is supported by substantial evidence.
    The trial court may not force the litigant to rely on abstract generalities, but must instruct
    9
    in specific terms that relate the party’s theory to the particular case.” (Soule v. General
    Motors Corp. (1994) 
    8 Cal.4th 548
    , 572 (Soule).) We first discuss whether the
    instruction should have been given and then consider whether any error in refusing to do
    so was prejudicial.
    1. Nondelegable Duty Instruction
    Defries’s proposed instruction on nondelegable duties was proper. Contrary to
    what the trial court stated, if Langston Motorsports had negligently assembled Defries’s
    dirt bike, then Yamaha would be liable as a matter of law. Although the legal authority
    for this proposition has been overshadowed by other legal concepts for reasons we
    explain below, it is nevertheless applicable, binding precedent.
    In Dow v. Holly Mfg. Co. (1958) 
    49 Cal.2d 720
     (Dow), a father and two children
    were found dead in their home from asphyxiation due to carbon monoxide poisoning.
    (Id. at p. 722.) The surviving family members (the mother and one of the children) sued
    the general contractor who built the home. (Ibid.) Although the general contractor
    planned and built the home, he had a subcontractor install the faulty heater that caused
    the deaths. (Ibid.) The subcontractor was not a party to the action. (Ibid.)
    Trial evidence showed, among other things, that “the orifices which admitted the
    gas [into the heater] for burning were too large” and that “as a result of the larger orifices
    sooting would occur, which, over a period of time, would result in carbon monoxide
    entering the house from the heater.” (Dow, supra, 49 Cal.2d at p. 723.) The jury found
    in plaintiffs’ favor. (Id. at p. 722.)
    10
    Our Supreme Court in Dow addressed “whether the general contractor was liable
    for the negligent installation of a defective gas heater by . . . his subcontractor.” (Dow,
    supra, 49 Cal.2d at p. 725.) It held that he was. (Id. at pp. 722, 728.) Noting that “there
    is no valid distinction between a general contractor constructing a building and using
    subcontractors to install equipment therein, and the manufacturer of an automobile
    buying parts not fabricated by it to install in the car,” and that “[t]here should be liability
    in both cases,” Dow concluded that “[i]t was [the general contractor]’s responsibility to
    construct a house equipped with an adequate heating system[,] and he could not negate
    that responsibility by delegating to [the subcontractor] the work of installing the
    necessary equipment for said heating system.” (Id. at pp. 727-728.)
    In another case six years later, our Supreme Court cited Dow for the proposition
    that “the manufacturer of a completed product [is] subject to vicarious liability for the
    negligence of his suppliers or subcontractors that resulted in defects in the completed
    product.” (Vandermark, supra, 61 Cal.2d at p. 261.)
    Vandermark involved a scenario analogous to Defries’s. “In October 1958
    plaintiff Chester Vandermark bought a new Ford automobile from . . . an authorized Ford
    dealer doing business as Maywood Bell Ford. About six weeks later, while driving on
    the San Bernardino Freeway, he lost control of the car. It went off the highway to the
    right and collided with a light post. He and his sister, plaintiff Mary Tresham, suffered
    serious injuries. They brought [an] action for damages against Maywood Bell Ford and
    the Ford Motor Company, which manufactured and assembled the car. They pleaded
    11
    causes of action for breach of warranty and negligence. The trial court granted Ford’s
    motion for a nonsuit on all causes of action.” (Vandermark, supra, 61 Cal.3d at p. 258.)
    One of the questions before our Supreme Court in Vandermark was whether the nonsuit
    was proper. (Id. at pp. 259-260.)
    The Vandermark plaintiffs “called an expert on the operation of hydraulic
    automobile brakes. In answer to hypothetical questions based on evidence in the record
    and his own knowledge of the braking system of the car, the expert testified as to the
    cause of the accident. It was his opinion that the brakes applied themselves owing to a
    failure of the piston in the master cylinder to retract far enough . . . . The expert also
    testified that the failure of the piston to retract sufficiently . . . could have been caused by
    dirt in the master cylinder, a defective or wrong-sized part, distortion of the firewall, or
    improper assembly or adjustment.” (Vandermark, supra, 61 Cal.2d at pp. 259-260.) In
    response, Ford noted that “the car passed through two other authorized Ford dealers
    before it was sold to Maywood Bell and that Maywood Bell removed the power steering
    unit before selling the car to Vandermark.” (Id. at p. 260.)
    The Court noted an additional fact: “It appears in the present case that Ford
    delegates the final steps in [the manufacturing] process to its authorized dealers. It does
    not deliver cars to its dealers that are ready to be driven away by the ultimate purchasers
    but relies on its dealers to make the final inspections, corrections, and adjustments
    necessary to make the cars ready for use.” (Vandermark, supra, 61 Cal.2d at p. 261.)
    (The Court, however, did not make clear whether the alleged defects in the braking
    12
    system would have come from Maywood Bell or one of the other authorized dealers who
    had the car.)
    Relying on Dow and other cases as well as the evidence before it, Vandermark
    held that the trial court erred in granting a nonsuit against Ford on plaintiffs’ negligence
    cause of action. (Vandermark, supra, 61 Cal.2d at p. 261.) The Court noted that Dow
    and other cases “focus responsibility for defects, whether negligently or nonnegligently
    caused, on the manufacturer of the completed product, and they apply regardless of what
    part of the manufacturing process the manufacturer chooses to delegate to third
    parties. . . . Since Ford, as the manufacturer of the completed product, cannot delegate its
    duty to have its cars delivered to the ultimate purchaser free from dangerous defects, it
    cannot escape liability on the ground that the defect in Vandermark’s car may have been
    caused by something one of its authorized dealers did or failed to do.” (Ibid.)
    Vandermark involved the direct manufacturer (Ford), but the Court there made it
    clear that the same concepts applied to downstream entities as well. In noting that
    negligent or nonnegligent defects are the manufacturer’s responsibility, Vandermark cited
    section 400 from the Restatement of Torts, which states that “[o]ne who puts out as his
    own product a chattel manufactured by another is subject to the same liability as though
    he were its manufacturer.” (Vandermark, supra, 61 Cal.2d at p. 261, citing Rest. Torts,
    § 400.) Dow also relied on the same Restatement section for its holding. (See Dow,
    supra, 49 Cal.2d at pp. 726-727.)
    13
    Under Dow and Vandermark, Defries was entitled to an instruction that Yamaha
    had a nondelegable duty to deliver a dirt bike to Defries free from dangerous defects,
    regardless of whether those defects were caused by Langston Motorsports, one of
    Yamaha’s dealers in the final assembly. Just as it is a general contractor’s responsibility
    to “construct a house equipped with an adequate heating system”—a responsibility that
    cannot be delegated to a subcontractor (Dow, supra, 49 Cal.2d at p. 728)—it was
    Yamaha’s nondelegable responsibility to deliver Defries a dirt bike free from dangerous
    defects. That analogy is made more direct by Vandermark’s statement that the
    nondelegable duty of a product manufacturer (here, a distributor) to deliver to the
    consumer a defect-free product means it cannot “escape liability on the ground that the
    defect . . . may have been caused by something one of its authorized dealers did or failed
    to do.” (Vandermark, supra, 61 Cal.2d at p. 261; accord, Caporale v. Raleigh Industries
    of America, Inc. (Fla. Dist. Ct. App. 1980) 
    382 So.2d 849
    , 851 [“The manufacturer
    cannot . . . disclaim liability for injuries to the ultimate purchaser of a product where the
    manufacturer knowingly relies on its dealer to put the product in a finished state.”]
    (Caporale), citing Vandermark; Sabloff v. Yamaha Motor Co. (N.J. Super. Ct. App. Div.
    1971) 
    113 N.J.Super. 279
    , 290, affd. (N.J. 1971) 
    59 N.J. 365
     [“where [the manufacturer]
    did not deliver its motorcycles to its dealer ready to be driven away by the ultimate
    purchasers but relied on the dealer to put into assembly the non-assembled parts and
    make the motorcycles ready for use, [the dealer] could not escape liability for a defect in
    14
    the motorcycle on the ground that it may have been caused by something that its
    2
    authorized dealer . . . did or failed to do”], citing Vandermark].)
    In finding otherwise, the trial court may have erred in two aspects of its reasoning.
    The first error was an unwarranted emphasis on the fact that Defries withdrew his claim
    for strict liability (manufacturing defect) during trial. The trial court noted when deciding
    on the proposed jury instruction, for instance, that Defries had withdrawn some of his
    strict liability claims. The idea of manufacturer liability for a product defect is typically
    associated with the concept of strict liability in modern legal thinking. Vandermark,
    which we have relied upon above for its discussion of negligence, is usually cited as part
    of a line of seminal cases on strict liability. (See, e.g., Jimenez v. Superior Court (2002)
    
    29 Cal.4th 473
    , 477-478 [noting that, a year after “California became the first state to
    allow recovery for strict products liability,” Vandermark “extended strict products
    2
    The pioneering principle underlying Vandermark is the “early step in the
    development of the law of products liability . . . the recognition of a manufacturer’s
    liability in negligence to an ultimate consumer without privity of contract.” (Seely v.
    White Motor Co. (1965) 
    63 Cal.2d 9
    , 15 [citing MacPherson v. Buick Motor Co. (1916)
    
    217 N.Y. 382
    , 389].) Judge Posner has observed: “The law of products liability has
    come to recognize what economists and businessmen have long known—that
    manufacturers are in a direct economic relationship with the ultimate consumers of their
    products even if they are not in privity with them.” (Jack Walters & Sons Corp. v.
    Morton Bldg., Inc. (7th Cir. 1984) 
    737 F.2d 698
    , 707.) Reflecting the manufacturer’s
    duty to the consumer, the Court of Appeal has relied on Vandermark to hold that, by
    making its dealers responsible for a vehicle recall, a car manufacturer “could not shift to
    the dealer the direct obligation of safety it owed the customer” when a car’s defect was
    not remedied. (Ford Motor Co. v. Robert J. Poeschl, Inc. (1971) 
    21 Cal.App.3d 694
    ,
    699; see also Springmeyer v. Ford Motor Co. (1998) 
    60 Cal.App.4th 1541
    , 1562-1563
    [“A manufacturer cannot delegate responsibility for the safety of its product to dealers,
    much less purchasers”].)

    liability to retailers”], italics removed; Loomis v. Amazon.com LLC (2021) 
    63 Cal.App.5th 466
    , 475-476 [describing similar history].)
    However, Defries’s withdrawal of his claim of strict liability based on a
    manufacturing defect did not preclude him from seeking recovery from Yamaha based on
    Langston Motorsports’s alleged negligence. It merely obligated Defries to prove that the
    defect was Langston Motorsports’s fault (i.e., based on its negligence), something it
    would not have to prove in a strict liability action. (See Merrill v. Navegar, Inc. (2001)
    
    26 Cal.4th 465
    , 479 [“[U]nder either a negligence or a strict liability theory of products
    liability . . . a plaintiff must prove that a defect caused injury. [Citations.] Under a
    negligence theory, a plaintiff must also prove ‘an additional element, namely, that the
    defect in the product was due to negligence of the defendant’”]; Rest.3d Torts, Products
    Liability, § 2 [“Negligence rests on a showing of fault leading to product defect. Strict
    liability rests merely on a showing of product defect”].) Given the prevalence of product
    defect cases focusing on strict liability theories, it might seem natural to assume that such
    cases can proceed only on such theories. But doing so would contravene Vandermark’s
    holding that a manufacturer is responsible for defects “whether negligently or
    nonnegligently caused” in any part of the manufacturing process, including “the final
    steps in that process” delegated to authorized dealers. (Vandermark, supra, 61 Cal.2d at
    p. 261.) Doing so would also confuse theories of liability with the primary right afforded
    to Defries under California law, which is the right to receive a product without dangerous
    defects. (See Barrett v. Superior Court (1990) 
    222 Cal.App.3d 1176
    , 1182 [“‘causes of

    action’” for negligence, strict liability, breach of implied warranty, and wrongful death
    actually comprised “one true ‘cause of action’”; “the four ‘causes of action’ were actually
    counts based on the same primary right of plaintiffs and the same primary duty of
    defendants, each of which merely alleged additional circumstances out of which the
    primary right and primary duty arose”]; Valentine v. Baxter Healthcare Corp. (1999) 
    68 Cal.App.4th 1467
    , 1487 [“the cause of action is based on the harm suffered, not the
    particular theory which the litigant asserts”].) Put in more direct terms, for purposes of
    analyzing Yamaha’s duty to deliver a defect-free product, Defries’s negligence claim is
    the same as strict liability, just in the form of liability for Langston Motorsports’
    3
    negligent assembly.
    The second error may have been the trial court’s belief that Defries failed to prove
    that Langston Motorsports was an agent of Yamaha. Cases have often framed issues
    surrounding vicarious liability and nondelegable duties in terms of agency. (See, e.g.,
    Maloney v. Rath (1968) 
    69 Cal.2d 442
    , 446 [“[u]nlike strict liability, a nondelegable duty
    operates, not as a substitute for liability based on negligence, but to assure that when a
    negligently caused harm occurs, the injured party will be compensated by the person
    whose activity caused the harm and who may therefore properly be held liable for the
    negligence of his agent, whether his agent was an employee or an independent
    contractor”], cited in CACI 3713.) And for the sake of argument, we will assume that the
    3 The trial court’s later ruling on Defries’s new trial motion appears to have
    recognized this, as the court noted in a discussion of prejudice that “the jury was clearly
    presented with the correct theory of liability, and was asked to find Yamaha negligent
    based on [Langston Motorsports]’s conduct.”
    17
    trial court was making an accurate statement when it observed that it heard “no evidence”
    that Langston Motorsports was Yamaha’s agent. However, the nondelegable duties
    developed in vicarious liability doctrine are based on public policy decisions that do not
    depend on an independent showing of the elements of agency. Rather, the duties serve
    goals such as placing responsibility on the entities “in the best position to ensure product
    safety,” where those in the production chain can “adjust the costs of liability” in their
    “continuing business relationship.” (Jimenez, supra, 29 Cal.4th at p. 479; see Srithong v.
    Total Investment Co. (1994) 
    23 Cal.App.4th 721
    , 727 [“the nondelegable duty rule
    advances the same purposes as other forms of vicarious liability”].)
    Vandermark requires the conclusion that an “authorized dealer” acts as the
    manufacturer’s agent by allowing liability when the dealer “make[s] the final inspections,
    corrections, and adjustments necessary to make the [vehicles] ready for use.”
    (Vandermark, supra, 61 Cal.2d at p. 261.) Consequently, Langston Motorsports’ agency
    for purposes of delivering a properly assembled dirt bike to the customer was established
    as a matter of law once Defries showed that Langston Motorsports was Yamaha’s
    authorized dealer and assembled the dirt bike. In contrast, Vandermark would not
    necessarily create liability for a manufacturer that sold a product to an entity other than
    an authorized dealer charged with assembling the product for sale to a customer, even
    where that entity negligently altered the product for a person’s use. This situation might
    often occur in a context other than a consumer’s retail purchase of a manufacturer’s
    product. (See In re Deep Vein Thrombosis (N.D. Cal. 2005)

    All of the cases discussed here, as well as our holding today, are in accord with a
    rule stated in the Restatement (Third) of Torts: Products Liability (1998): “When the
    manufacturer delegates some aspect of manufacture, such as final assembly or inspection,
    to a subsequent seller, the manufacturer may be subject to liability under rules of
    vicarious liability for a defect that was introduced into the product after it left the hands
    of the manufacturer.” (§ 2, comment c.) This rule has the laudable effect of encouraging
    a manufacturer or distributor like Yamaha to act to safeguard proper assembly by its
    various dealers, including attempting to ensure that negligent conduct in one location
    does not repeat elsewhere. It further ensures that a plaintiff does not have the burden of
    discovering and proving which entity in the production chain is responsible for negligent
    assembly: Yamaha for insufficient instructions or safeguards that would ensure proper
    5
    assembly, or a dealer for failing to execute Yamaha’s commands properly.
    5
    The dissent suggests that if we are correct that Vandermark held that a
    manufacturer could be liable for its dealer’s negligent assembly of its product, the
    decision “would have been a bombshell.” (Dis. opn., post, at p. 10.) That is in fact how
    the leading torts scholar of the day, William L. Prosser, viewed Vandermark, calling it
    “the most extreme decision of all those applying strict liability to date.” (William L.
    Prosser, The Fall of the Citadel (Strict Liability to the Consumer) (1966) Minn. L. Rev.
    791, 827-828.) As we do, Prosser recognized that Vandermark “held that the obligation
    of the manufacturer to supply the ultimate purchaser with an automobile safe for his use
    was such that it could not be delegated to the dealer, and that it could not escape liability
    for an unsafe product on the ground that the defect . . . might have been caused by
    something the dealer ‘did or failed to do’ in servicing the car before final delivery.” (Id.
    at p. 828.) Prosser suggested that manufacturer liability for dealer negligence under
    Vandermark be limited “only to the delegation of ‘servicing,’ or other work completing
    the product.” (Prosser, at p. 828) He stated that “it can scarcely be supposed that the
    manufacturer would be liable, where, for example, a bottle of beer is cracked by the
    dealer while it was being handled.” (Ibid.) Prosser’s suggestion that under Vandermark
    20
    In contending that the instruction was properly denied, Yamaha argues that
    Defries waived his claim of instructional error by failing to proffer a version of CACI
    3713 with the bracketed portions filled in. Although a court “may refuse to give a
    requested instruction when the blank spaces are not filled in” (Timmons v. Assembly of
    God Church (1974) 
    40 Cal.App.3d 31
    , 38), the court expressed no concern with this at
    the time the court rejected CACI 3713. The court accepted or took under submission
    other disputed instructions that Defries submitted with bracketed portions without
    suggesting that the brackets were an inherent flaw at that time. In contrast, when the
    court considered Defries’s requested instruction on present cash value, the court
    specifically noted its concern that Defries had not chosen which one of two bracketed
    options the form provided.
    More importantly, however, the only bracketed portions of CACI 3713 that might
    have been difficult to fill in would have been the portions explaining where the
    a manufacturer’s liability for dealer negligence lies only for work, such as product
    assembly, that it has delegated to the dealer—without liability for dealer negligence
    untethered to any such delegation—presaged the view ultimately adopted by the
    Restatement (Third) of Torts three decades later (§ 2, comment c) that we join today. As
    to that type of manufacturer liability, Prosser recognized in 1966 that Vandermark “at
    least eliminates any intervening negligence, whether of act or of omission, in preparing
    the product for final sale.” (Prosser, The Fall of the Citadel (Strict Liability to the
    Consumer), supra, at p. 828; see also, e.g., Vaughn v. Chrysler Corp. (10th Cir. 1971)
    
    442 F.2d 619
    , 620-622 [holding car manufacturer liable for the negligence of a dealer and
    citing Vandermark for the proposition that the “fact that the subject truck was not
    defective in original manufacture is no defense”]; David W. Leebron, An Introduction to
    Products Liability: Origins, Issues, and Trends (1990) Ann.Surv.Amer.L. 395, 424,
    fn.150 [citing Vandermark for the proposition that “courts early on rejected attempts by
    automobile manufacturers to avoid strict liability by delegating final tasks, such as
    inspection of the brakes, to dealers”].)
    21
    nondelegable duty arises from, and the court had asked Defries where he thought that
    duty came from. The first paragraph of the form instruction states: “[Name of defendant]
    has a duty that cannot be delegated to another person arising from [insert name, popular
    name, or number of regulation, statute, or ordinance/a contract between the parties/other,
    e.g., the landlord-tenant relationship]. Under this duty, [insert requirements of
    regulation, statute, or ordinance or otherwise describe duty].” When discussing this
    instruction, the court asked Defries for his “basis for saying it’s not delegable,” to which
    his counsel stated, “[b]ecause under the law it’s a matter of law that the manufacturer,
    distributor of a product has a nondelegable duty to provide a safe product to the
    consumer.” The fact that the court later noted, in its ruling denying Defries’s new trial
    motion, that “the proposed instruction could have been rejected merely because it was
    incomplete,” does not preclude Defries from raising the instructional argument here, and
    we decline to find that he has waived it.
    Accordingly, the trial court erred in refusing to give Defries’s proposed jury
    instruction on nondelegable duties.
    2. Prejudice
    In reviewing a judgment where the appellant has raised the denial of a new trial
    motion as an issue, “an appellate court has the obligation to review ‘the entire record,
    including the evidence, so as to make an independent determination whether the error
    was prejudicial.’” (Hasson v. Ford Motor Co., supra, 32 Cal.3d at 417, fn. 10.)
    22
    “[T]here is no rule of automatic reversal or ‘inherent’ prejudice applicable to any
    category of civil instructional error, whether of commission or omission.” (Soule, 
    supra,
    8 Cal.4th at p. 580.) Rather, “[i]nstructional error in a civil case is prejudicial ‘where it
    seems probable’ that the error ‘prejudicially affected the verdict.’” (Ibid.) In other
    words, “[i]n cases of instructional error, a reasonable probability that ‘the jury would
    have returned a more favorable verdict’ is sufficient to establish prejudice.” (Wallace v.
    County of Stanislaus (2016) 
    245 Cal.App.4th 109
    , 132.)
    In determining whether “an error of instructional omission” was prejudicial, the
    reviewing court evaluates “(1) the state of the evidence, (2) the effect of other
    instructions, (3) the effect of counsel’s arguments, and (4) any indications by the jury
    itself that it was misled.” (Soule, 
    supra,
     8 Cal.4th at pp. 580-581, fn. omitted.) In
    reviewing claims of instructional error, we “view[] the evidence in the light most
    favorable to the appellant.” (Orichian v. BMW of North America, LLC (2014) 
    226 Cal.App.4th 1322
    , 1333.) “[W]e must assume that the jury might have believed the
    evidence upon which the instruction favorable to the losing party was predicated, and that
    if the correct instruction had been given upon that subject the jury might have rendered a
    verdict in favor of the losing party.” (Henderson v. Harnischfeger Corp. (1974) 
    12 Cal.3d 663
    , 674.)
    We find that the error in denying Defries’s jury instruction was prejudicial here.
    First, there was substantial evidence that Langston Motorsports negligently
    assembled Defries’s dirt bike. This included expert witness testimony that one or both of
    23
    the bolts in the throttle assembly had been improperly tightened (and that this improper
    tightening can cause the throttle to come off the handlebar), as well as uncontroverted
    testimony that another part of the throttle assembly—the throttle cable—had been
    incorrectly routed. Given the concession that at least one part of the assembly had been
    faulty, and Defries’s experts’ view that the improper bolts in the throttle assembly is what
    led to the crash, it would have been reasonable for a jury to conclude that Langston
    Motorsports was negligent had it been allowed to make such a finding. Although there
    was also expert testimony (namely Yamaha’s) to the effect that the throttle bolts had been
    torqued correctly, we must view the evidence in the light most favorable to Defries and
    assume that the jury might have believed the evidence he presented. (See Henderson v.
    Harnischfeger Corp., 
    supra,
     12 Cal.3d at p. 674; Orichian v. BMW of North America,
    LLC, supra, 226 Cal.App.4th at p. 1333.)
    In contesting this point, Yamaha points to the trial court’s ruling on the motion for
    new trial, specifically the trial court’s statement that “there was virtually no evidence
    upon which the jury could have based a conclusion that [Langston Motorsports]
    negligently installed the throttle assembly.” Because we must independently determine
    whether the denial of a new trial was prejudicial (Hasson v. Ford Motor Co., supra, 32
    Cal.3d at p. 417, fn. 10), however, we accord no deference to the trial court’s contrary
    conclusion here, as it was not one on a witness’s credibility. (See People v. Vivar (2021)
    
    11 Cal.5th 510
    , 524 [independent review standard “accords substantial weight to the trial
    24
    court’s credibility findings”].) As we have stated, there was substantial evidence tending
    to prove Langston Motorsports’s negligence.
    Second, the “effect of other instructions” (Soule, 
    supra,
     8 Cal.4th at p. 581) left
    the jury no way of knowing, other than by guessing, that any negligence on Langston
    Motorsports’s part was properly imputed to Yamaha as a matter of law. Nothing in the
    other instructions given to the jury or the special verdict form informed the jury that
    Langston Motorsports’s negligence meant Yamaha’s negligence. Although Yamaha
    notes that the jury was instructed that Yamaha “cannot avoid responsibility just because
    some other person, condition or event was also a substantial factor in causing” Defries’s
    harm, this instruction relates to situations where multiple causes lead to an injury, not the
    relevant circumstance of one cause being attributed by law to multiple people.
    Third, nothing Defries’s counsel could have argued could have ameliorated the
    effect of the missing instruction, as a crucial link in the chain of reasoning had not been
    provided to the jury. (See Spriesterbach v. Holland (2013) 
    215 Cal.App.4th 255
    , 274
    [“‘“[W]e presume that jurors treat the court’s instructions as a statement of the law by a
    judge, and the [attorney’s] comments as words spoken by an advocate in an attempt to
    persuade”’”].) This is not an instance, for example, where counsel’s arguments made
    error less prejudicial because they helped focus the jury’s attention on how the broad—
    yet sufficient—instructions given could be applied to the facts of the case. (E.g., Soule,
    supra, 8 Cal.4th at p. 582 [finding no prejudice in part because counsel’s “argument
    25
    uniformly supported the reasonable inference that the general causation instruction
    6
    allowed”].)
    On the fourth Soule factor—whether there are “any indications by the jury itself
    that it was misled” (Soule, 
    supra,
     8 Cal.4th at p. 581, fn. omitted)—Defries does not
    contend that any such indications exist. However, in light of the state of the evidence, the
    effect of other instructions, and the effect of counsel’s arguments, we find a reasonable
    probability that the jury would have returned a verdict in Defries’s favor on negligence
    had it been given proper instructions. We therefore find that the trial court abused its
    7
    discretion in denying Defries’s motion for new trial.
    B. Motions in Limine
    “Trial court rulings on the admissibility of evidence, whether in limine or during
    trial, are generally reviewed for abuse of discretion. [Citations.] ‘The trial court’s error
    6
    In any event, to the extent we would consider counsel’s arguments as statements
    of law to the jury, Yamaha’s closing argument would likely have added to Defries’s
    prejudice. In its closing argument, Yamaha told the jury that it was not to decide whether
    Langston Motorsports was negligent, but rather to decide whether Yamaha was because
    of a failure to advise double-checking on the bolts. Counsel stated: “You’re not deciding
    whether Langston [Motorsports] or [the employee who assembled the dirt bike]. Your
    question you have to answer is was Yamaha negligent here. Yamaha should have given
    this warning to double-check the tightness of the bolts.” Moments later, Yamaha
    repeated the point: “When deciding the issue of negligence it’s not looking at, did the
    dealership screw something up and do something wrong here. It’s, did Yamaha do
    something wrong in the instructions or warnings that they gave to the dealership.” A jury
    heeding Yamaha’s statements would have avoided deciding the very issue that Defries
    was entitled to ask the jury to decide: whether Yamaha could be found negligent because
    of Langston Motorsports’s actions.
    7
    In the unpublished portion of this opinion, we reject Defries’s other claims of
    error.
    26
    in excluding evidence is grounds for reversing a judgment only if the party appealing
    demonstrates a “miscarriage of justice”—that is, that a different result would have been
    probable if the error had not occurred.’” (Pannu v. Land Rover North America, Inc.
    (2011) 
    191 Cal.App.4th 1298
    , 1317.)
    Defries contends that the trial court erred in granting (in whole or in part) four of
    Yamaha’s motions in limine. As we explain, we find no error.
    1. Motion in Limine: Prior Incidents
    Yamaha’s motion in limine sought to exclude all evidence relating to two other
    incidents involving the same model of dirt bike as Defries’s. The evidence of both other
    incidents was internal Yamaha customer relations reports.
    In one incident (the 2011 incident), a Yamaha customer relations report stated that
    a customer in North Carolina “‘bought the bike & his son . . . had an accident on the 1st
    ride. [The customer] says the throttle came off the handlebars & the bike took off up into
    the woods.’” Although Yamaha requested that the customer take the dirt bike to a local
    dealership for inspection, the customer never did so, and no additional information was
    ever provided.
    In discussing the 2011 incident, Yamaha contended that the document describing
    the incident was excludable as “pure hearsay because it’s just someone calling in and
    they are just writing down verbatim what the person says over the phone. [¶] This is
    similar to a police report where a police officer takes a statement from a witness at a
    scene, summarizes the statement, includes it in their police report, and then someone then
    27
    wants to read that statement into evidence and use it against a defendant in trial. You
    can’t do that. That’s hearsay. You would have to go and take the deposition of that
    witness so that everyone has an opportunity to examine them about this and test the
    reliability of the statement.”
    The trial court granted the motion in limine. It concluded that the document
    describing the 2011 incident was a business record but that any probative value would be
    outweighed by undue prejudice. (See Evid. Code, § 352.) The trial court stated: “A
    limiting instruction would have to be crafted . . . . If I had to craft some kind of limiting
    instruction, it would essentially be, jury, you can’t use this for any purpose other than a
    call was made from some unknown person, said this. You wouldn’t be able to say
    anything else beyond that.”
    The trial court was well within its discretion to exclude the evidence under
    Evidence Code section 352. As the trial court correctly suggested, the jury would not
    have properly been able to use the documents as evidence that either the 2011 or 2014
    incidents occurred, so any probative value it may have had was substantially outweighed
    by the danger of undue prejudice, confusing the issues, or misleading the jury. (See Evid.
    Code, § 352.)
    The document describing the 2011 incident would not have been properly
    admitted to prove the existence of the 2011 incident because the document contained two
    levels of hearsay, and at least one of the levels of hearsay did not fall within an exception
    to the hearsay rule.
    28
    “‘“Hearsay evidence” is evidence of a statement that was made other than by a
    witness while testifying at the hearing and that is offered to prove the truth of the matter
    stated.’ (Evid. Code, § 1200, subd. (a).) Unless otherwise provided by law, hearsay
    evidence is inadmissible. (Evid. Code, § 1200, subd. (b).)” (Daniels v. Department of
    Motor Vehicles (1983) 
    33 Cal.3d 532
    , 537 (Daniels).) One exception is Evidence Code
    section 1271, the business record exception. “That statute makes admissible evidence of
    a writing made as a record of an event when (a) the writing was made in the regular
    course of business; (b) the writing was made at or near the time of the act, condition or
    event, (c) the custodian or other qualified witness testifies to its identity and the mode of
    its preparation; and (d) the source of information and method and time of preparation
    were such as to indicate its trustworthiness.” (Daniels, supra, 33 Cal.3d at p. 537.)
    “Double hearsay is not categorically inadmissible; instead, a double hearsay
    statement is admissible if each level of hearsay comes within an exception to the hearsay
    rule.” (Caliber Paving Company, Inc. v. Rexford Industrial Realty and Management, Inc.
    (2020) 
    54 Cal.App.5th 175
    , 189.)
    We can assume for the sake of argument that the first level of hearsay—the
    Yamaha employee’s hearsay—fell under the business records exception. That is, we can
    assume that the document was made in the regular course of Yamaha’s business, was
    made at or near the time of the customer’s report, that the Yamaha employee or some
    other qualified witness could testify to the document’s identity and mode of preparation,
    29
    and the source of information and method and time of preparation were such as to
    indicate its trustworthiness. (See Evid. Code, § 1271.)
    We cannot assume, however, that the second level of hearsay—the customer’s
    hearsay—also fell under the business records exception, as Defries contends. There was
    nothing in the source of its information to indicate any level of trustworthiness. Although
    neither party has cited the case, Daniels is directly on point here. In Daniels, our
    Supreme Court considered whether a report made by a crash accident victim to the
    Department of Motor Vehicles (DMV) qualified as a business record. (Daniels, supra,
    33 Cal.3d at pp. 534-535.) The Court held that it was not. (Id. at pp. 537-538.) It stated
    that “[a]lthough it may be the regular course of business for the [DMV] to receive the
    report, it undoubtedly is not in the regular course of business for the citizen author to
    make such a report. And, it is this aspect of the report that bears on the trustworthiness
    factor contemplated by this exception to the hearsay rule.” (Ibid.)
    Daniels’s rationale applies to the customer’s hearsay. Even though creating and
    documenting incident reports might be in Yamaha’s regular course of business (which
    pertains to the first level of hearsay), customers making such reports (which pertains to
    the second level) are not in Yamaha’s regular course of business. As Yamaha correctly
    noted when arguing the motion in limine, this is analogous to the admission of the
    contents of a police report without any means of testing the declarant’s reliability.
    In sum, the trial court properly excluded the document describing the 2011
    incident.
    30
    In the other incident (the 2014 incident), the customer relations report stated that a
    customer “‘purchased the unit Friday 10/31/2014. Went to the track 11/2/2014 & had an
    accident. [Customer] claims it had nothing to do with him. He says he went over a jump
    and upon landing the throttle broke completely off. [Customer] says the tube broke off
    the throttle housing and was hanging off of the bike.’” An inspection revealed that the
    throttle tube had broken due to an impact with the ground during the crash, which was
    not the same as the throttle assembly falling off of the handlebar.
    Defries essentially conceded that the 2014 incident was excludable because it was
    not substantially similar. His counsel stated: “I will concede that the one from 2014 may
    lack substantial similarity because what happened there, the guy went out to the jump and
    the throttle tube broke causing the throttle to come off the handlebar.” In arguing the
    motion, the parties hardly mentioned the 2014 incident.
    In any event, the document describing the 2014 incident was also properly
    excluded. Not only would this document also fail to be admissible double hearsay for the
    same reason the document describing the 2011 incident fails, but the record also supports
    Defries’s concession the 2014 incident was not substantially similar. (See Ault v.
    International Harvester Co. (1974) 
    13 Cal.3d 113
    , 121-122 [“Evidence of other accidents
    is admissible to prove a defective condition, knowledge, or the cause of an accident,
    provided that the circumstances of the other accidents are similar and not too remote”].)
    We find no error.
    31
    2. Motion in Limine: Darnell’s Throttle Cable Test
    Another motion in limine sought to exclude evidence from Defries’s expert
    Russell Darnell. Yamaha believed that Defries would introduce evidence of an
    experiment Darnell performed, in which he put the throttle assembly from Defries’s dirt
    bike back on, and use that experiment as a basis for his opinion that the accident was
    caused by the throttle assembly falling off the handlebar. The experiment was apparently
    meant to show that the throttle cable was long enough to have come off of the handlebar
    undamaged, thus disproving Yamaha’s contention that the throttle cable would have
    prevented the assembly from falling off the handlebar.
    In conjunction with argument on the motion, Darnell testified outside the jury’s
    presence. Defries’s dirt bike was in the courtroom, so Darnell demonstrated to the trial
    court what he did in the experiment. The trial court ruled that it would allow Darnell to
    “testify to his general expert opinion about the crash” but granted the motion to exclude
    the experiment itself.
    “In the field of products liability, the problem of admitting experimental evidence
    is a very real one; attorneys on both sides must rely upon expert testimony and accident
    reconstruction experimentation; that is particularly true where causation is a major issue.”
    (Culpepper v. Volkswagen of America, Inc. (1973) 
    33 Cal.App.3d 510
    , 521 (Culpepper).)
    “Admissibility of experimental evidence depends upon proof of the following
    foundational items: (1) The experiment must be relevant [citations]; (2) the experiment
    must have been conducted under substantially similar conditions as those of the actual
    32
    occurrence [citation]; and (3) the evidence of the experiment will not consume undue
    time, confuse the issues or mislead the jury.” (Culpepper, supra, 33 Cal.App.3d at p.
    521.) “The proponent of the evidence need not show that conditions at the time of the
    experiment were identical to the conditions at the time in dispute; substantial similarity is
    all that is required.” (Staples v. Hoefke (1987) 
    189 Cal.App.3d 1397
    , 1416.)
    The trial court ruled that Darnell’s experiment was performed under circumstances
    “clearly different” from the accident. We find no abuse of discretion. First, it was
    uncontroverted that: (1) the throttle assembly had been assembled at the time of the
    accident, but it had been partially disassembled prior to the experiment and not
    reassembled, and that the difference would have accounted for “probably half an inch” of
    slack; (2) the brake reservoir on the right handlebar had been rotated about 90 degrees as
    a result of the crash and had not been adjusted back; and (3) Defries was riding straight at
    the time of the accident, but the only photographs Darnell had taken of his experiment
    showed that the handlebars had been turned to the left, and turning the handlebars left
    shortens the distance necessary for the throttle assembly to attach or detach from the
    handlebar. Darnell believed that these differences were insignificant, but he also
    effectively conceded that his opinion on the significance of the differences was not based
    on empirical data, but rather his own expertise.
    Second, and more importantly, the trial court’s finding that the circumstances of
    Darnell’s test were “clearly different” from that of the crash was based in part on the trial
    court’s observation of what the experiment entailed, based on Darnell recreating it while
    33
    testifying for the motion. It was thus in a position to see for itself whether any
    differences would have been significant in a relevant way.
    In contending that the ruling was an abuse of discretion, Defries states in passing
    that the trial court also erred in prohibiting Darnell’s experiment “on a new exemplar dirt
    bike, which he had disclosed during his deposition he would perform at trial.” The only
    portion of the record he cites to in support of this claim, however, is Darnell’s testimony
    during the motion in limine. Darnell’s claim during court testimony that he had disclosed
    the test during a deposition is not the same as a citation to the portion of his deposition
    where he made the disclosure, assuming such a disclosure exists. And without deposition
    testimony from Darnell that he sought to perform the experiment on an exemplar dirt bike
    at trial, he would have been prohibited from doing so. (See Easterby v. Clark (2009) 
    171 Cal.App.4th 772
    , 780 (Easterby).) We accordingly treat this claim as forfeited for failure
    to properly cite the record. (City of Lincoln v. Barringer (2002) 
    102 Cal.App.4th 1211
    ,
    1239.)
    We conclude that the trial court’s ruling as to Darnell’s experiment was not an
    abuse of discretion.
    3. Motion in Limine: Darnell’s Designation as an Expert on Warnings
    In another motion in limine, Yamaha sought to exclude any testimony or opinions
    from Darnell regarding warnings, contending that he lacked proper qualification as an
    expert on that topic. As with his experimental evidence, Darnell testified outside the
    presence of the jury about this matter. Following Darnell’s testimony, the trial court,
    34
    addressing Darnell, stated: “I think you’re undeniably [qualified] to talk about safety and
    what the best practices [for dirt bike assembly] would be. But I have heard nothing that
    leads me to believe that you are qualified to say what the language of the manual should
    be in terms of, you know, this box should be in all bold, and should have an exclamation,
    and say recheck it. [¶] . . . [Y]ou could easily talk about, you know, the best practice
    would be, after you torque that bolt down, before it leaves the shop, to double check it
    every single time to make sure no one has walked off with it. I think you can testify to
    that. But I don’t think you are qualified, as a witness, to talk about how the manual was
    designed or what the manual should say.” The trial court continued: “So that motion is –
    I guess I would say granted in part. To the extent he’s opining on general safety issues
    and this motion encompassed that, or that consumers would not be expected to check the
    bolts, he can opine on that as well. He just can’t opine on the specific warnings here in
    these manuals.”
    Evidence Code section 720, subdivision (a), allows a witness to testify as an
    expert “‘if he has special knowledge, skill, experience, training, or education sufficient to
    qualify him as an expert on the subject to which his testimony relates.’ . . . [A]n expert’s
    qualifications ‘must be related to the particular subject upon which he is giving expert
    testimony. Qualifications on related subject matter are insufficient.’” (People v. Chavez
    (1985) 
    39 Cal.3d 823
    , 828.) “We are required to uphold the trial judge’s ruling on the
    question of an expert’s qualifications absent an abuse of discretion.” (Ibid.)
    35
    The trial court’s ruling was well within its discretion. Darnell’s responses to
    questions from Yamaha and the trial court showed that he was not qualified to opine on
    warnings. During Yamaha’s cross-examination Darnell conceded that he had never
    appeared as an expert on the design or wording of warnings; did not identify warnings,
    human factors, or ergonomics as fields of expertise on his resumé and lacked a degree or
    certification in those subjects; and never designed warnings for consumer motor vehicles.
    The trial court confirmed that Darnell had not designed any motorcycle warnings like
    those at issue in this case.
    Given this testimony, the trial court correctly concluded that Darnell was not
    qualified as an expert on the topic of warnings. The proposition that Defries relies on in
    support of a contrary conclusion, that “the degree of [an expert’s] knowledge is a matter
    which affects the weight of his testimony, not its admissibility” (People v. Stuller (1970)
    
    10 Cal.App.3d 582
    , 597), only comes into play once it is determined that the witness is
    qualified as an expert in the area at issue. Darnell was not. We find no error in the trial
    court’s ruling.
    4. Motion in Limine: Brignola’s Post-Deposition Opinions
    In the last motion in limine Defries challenges on appeal, Yamaha sought to
    exclude a report from Defries’s other expert witness, Christopher Brignola, produced 22
    days before trial in May 2019. According to the motion, during Brignola’s deposition in
    December 2018, he confirmed that he had stated all opinions he intended to formulate for
    36
    the case and that Defries had asked him to do no additional work. Brignola did not
    produce any report before or at his deposition.
    The later report contained six opinions. Opinion #1 stated: “More likely than not,
    the subject throttle was not on the handlebar at some point during the crash.” Opinion #4
    stated: “I disagree with [Yamaha’s expert Erin Higinbotham’s] opinion stating that Dr.
    Darnell’s assertion of a vibrational weakness or over vibration concept as related to the
    subject motorcycle’s throttle assembly has no scientific basis.” Opinion #6 stated: “I
    disagree with [Langston Motorsports’s expert Steven Anderson’s] identification of the
    throttle cable as the kill switch wire.”
    Following argument, the trial court granted the motion in limine as to opinion #1
    and opinion #6. It stated that opinion #1 and opinion #6 were “truly not at all covered in
    the deposition” and that it would not be possible for Brignola to be redeposed given the
    trial date. As to opinion #4, the trial court granted the motion as to the case in chief only,
    meaning that opinion #4 could be used only for rebuttal purposes. The trial court denied
    the motion as to the other three opinions, stating that they were “clarifications of existing
    positions, not brand new issues.”
    Although on appeal Defries challenges the trial court’s ruling on the motion in
    limine broadly, opinion #6, which related to an opinion by one of Langston Motorsports’s
    experts who never testified at trial, is not relevant. Indeed, Defries’s opening brief does
    not even specifically identify opinion #6.
    37
    With regard to opinion #1 (whether the throttle came off the handlebar during the
    crash) and opinion #4 (rebutting Yamaha’s expert’s opinion on vibrational weakness), we
    find no abuse of discretion. “[A] party’s expert may not offer testimony at trial that
    exceeds the scope of his deposition testimony if the opposing party has no notice or
    expectation that the expert will offer the new testimony, or if notice of the new testimony
    comes at a time when deposing the expert is unreasonably difficult.” (Easterby, supra,
    171 Cal.App.4th at p. 780.) Given that Brignola’s report, which acted as notice of new
    testimony, was disclosed just three weeks before trial, it was well within the trial court’s
    discretion to find that deposing Brignola again would have been unreasonably difficult.
    Defries does not contend that opinions #1 and #4 were covered in Brignola’s
    deposition, so we consider only whether the report was produced too late. In contending
    that it was not, Defries characterizes this case as similar to Easterby, where the Court of
    Appeal found the exclusion of expert testimony to be prejudicial error. (Easterby, supra,
    171 Cal.App.4th at p. 783.) The time period involved in Easterby, however, was three
    months, not three weeks, so the “defendants in [that] case had the opportunity to take [the
    expert]’s deposition in light of his changed opinion and prepare for cross-examination
    and rebuttal of his testimony.” (Id. at p. 780.) The facts of Easterby therefore do not
    help Defries.
    Defries also contends that the ruling was in error because, according to him,
    Brignola had initially been identified as an expert who would opine on causation,
    something both opinion #1 and opinion #4 cover. However, as Yamaha notes, during his
    38
    deposition, Brignola indicated that Darnell would be the sole expert witness on causation.
    In that same deposition Brignola also acknowledged that he had stated all of the opinions
    he intended to formulate for the case. Under these circumstances, whether Brignola had
    at one point been designated as an expert on causation is irrelevant, as Yamaha was
    entitled to rely on Brignola’s disclaimer unless it had a reasonable opportunity to depose
    him again on his causation opinions before trial. (See Easterby, supra, 171 Cal.App.4th
    at p. 780.)
    Finally, Defries emphasizes that the timing of Brignola’s report in May 2019 was
    “logical[],” given that three of Yamaha’s experts were deposed in January and March
    2019, after Brignola’s December 2018 deposition. Brignola needed additional time,
    Defries contends, to form opinions in response to Yamaha’s experts. However, there is
    no reason to believe—and Defries offers none—that opinion #1 was a rebuttal opinion,
    and the trial court allowed Brignola to offer opinion #4 in rebuttal. Thus, in substance,
    the trial court allowed Brignola to offer opinions in response to Yamaha’s experts.
    Defries does not demonstrate an abuse of discretion on this basis.
    8
    Accordingly, we find no error in the court’s rulings on the motions in limine.
    8
    Our conclusions here do not necessarily preclude Brignola from testifying as to
    causation in a new trial on remand. Given our reversal of the judgment as to the
    negligence cause of action, discovery will reopen, and the “last date for completing
    discovery is 15 days before the date initially set for the new trial of the action.”
    (Fairmont Ins. Co. v. Superior Court (2000) 
    22 Cal.4th 245
    , 247.)
    39
    C. Breach of Implied Warranty
    Defries contends that the jury verdict in Yamaha’s favor on the breach of implied
    warranty count must be overturned because there was no evidence supporting Yamaha’s
    affirmative defense that the warranty had been disclaimed.
    Although styled as a challenge to the sufficiency of the evidence, Defries’s
    argument here is actually an attack on the special verdict form. Because Defries did not
    object to the special verdict form before the court discharged the jury, the claim was
    forfeited.
    “Unlike express warranties, which are basically contractual in nature, the implied
    warranty of merchantability arises by operation of law. [Citation.] It does not ‘impose a
    general requirement that goods precisely fulfill the expectation of the buyer. Instead, it
    provides for a minimum level of quality.’” (American Suzuki Motor Corp. v. Superior
    Court (1995) 
    37 Cal.App.4th 1291
    , 1295-1296.) The implied warranty of
    merchantability can be disclaimed. (Cal. U. Com. Code, § 2316, subd. (2).)
    Defries’s contention focuses on question 12 of the special verdict form, which
    read: “Did the sale of the 2017 Yamaha YZ250 motorcycle include notice that would
    have made a buyer aware that it was being sold without any representation relating to the
    quality that a buyer would expect?” The jury answered the question in the affirmative,
    40
    thus finding that Yamaha had shown an affirmative defense to the breach of implied
    9
    warranty claim.
    The wording of question 12 accords with California Uniform Commercial Code
    section 2316, subdivision (3)(a), which states that “[u]nless the circumstances indicate
    otherwise, all implied warranties are excluded by expressions like ‘as is,’ ‘with all faults’
    or other language which in common understanding calls the buyer’s attention to the
    exclusion of warranties and makes plain that there is no implied warranty.” In addition,
    the parties had agreed on the wording of question 12 as well as all of the other questions
    on the special verdict form.
    There is no indication in the record, nor does Defries attempt to show, that he
    believed question 12 was deficient after he had acquiesced to its wording and before the
    jury was discharged. On appeal, however, Defries contends that “absolutely no evidence
    was presented at trial that written ‘notice’ was attached to the dirt bike stating it was
    being sold ‘as is’ or ‘with all faults’; that the buyer was accepting the entire risk of
    9
    The jury also found inapplicable the implied warranty of fitness for a particular
    purpose. “An implied warranty of fitness for a particular purpose arises only where (1)
    the purchaser at the time of contracting intends to use the goods for a particular purpose,
    (2) the seller at the time of contracting has reason to know of this particular purpose, (3)
    the buyer relies on the seller’s skill or judgment to select or furnish goods suitable for the
    particular purpose, and (4) the seller at the time of contracting has reason to know that the
    buyer is relying on such skill and judgment.” (Keith v. Buchanan (1985) 
    173 Cal.App.3d 13
    , 25.) The jury answered no to the question, “[a]t the time of the purchase, did
    Yamaha . . . know or have reason to know that Plaintiff Chad Defries intended to use the
    2017 Yamaha YZ250 motorcycle for a particular purpose?”
    41
    quality and performance; and that if the dirt bike was defective, the buyer would be
    responsible for the cost of all servicing and repair” (italics added).
    The characteristics Defries cites do not come from California Uniform
    Commercial Code section 2316. Rather, they come from Civil Code section 1792.4,
    10
    which is part of the Song-Beverly Consumer Warranty Act.
    Defries first claimed that the special verdict form needed to have included these
    elements from the Song-Beverly Consumer Warranty Act in his reply brief to his motion
    for new trial.
    A party forfeits “any objection to the special verdict form by failing to object
    before the court discharge[s] the jury.” (Jensen v. BMW of North America, Inc. (1995) 
    35 Cal.App.4th 112
    , 131.) Here, the objection was not made before the jury was discharged.
    Accordingly, the objection was forfeited.
    In any event, even if the issue had not been forfeited, we note that Defries’s claim
    that insufficient evidence supported the breach of implied warranty count would have
    failed on the merits. “[W]here a party to a civil lawsuit claims a jury verdict is not
    10
    Civil Code section 1792.4, subdivision (a) provides: “No sale of goods,
    governed by the provisions of this chapter, on an ‘as is’ or ‘with all faults’ basis, shall be
    effective to disclaim the implied warranty of merchantability or, where applicable, the
    implied warranty of fitness, unless a conspicuous writing is attached to the goods which
    clearly informs the buyer, prior to the sale, in simple and concise language of each of the
    following: [¶] (1) The goods are being sold on an ‘as is’ or ‘with all faults’ basis. [¶]
    (2) The entire risk as to the quality and performance of the goods is with the buyer. [¶]
    (3) Should the goods prove defective following their purchase, the buyer and not the
    manufacturer, distributor, or retailer assumes the entire cost of all necessary servicing or
    repair.”
    42
    supported by the evidence, but asserts no error in the jury instructions, the adequacy of
    the evidence must be measured against the instructions given the jury.” (Null v. City of
    Los Angeles (1988) 
    206 Cal.App.3d 1258
    , 1535, italics added. Assuming that Defries
    had not in fact challenged the jury instructions on this count, he would have failed to
    show that the evidence was insufficient in the way he now contends on appeal. This is
    because the errors he now claims—such that a written notice needed to have been
    attached to the dirt bike, that the buyer was accepting the entire risk of quality and
    performance, and that the buyer would be responsible for all service and repair costs on a
    defective dirt bike—were not part of the instructions given to the jury at all; at least,
    Defries has not shown they were, given that the record does not contain the actual
    instructions themselves. (See Jameson v. Desta (2018) 
    5 Cal.5th 594
    , 609 [“‘Failure to
    provide an adequate record on an issue requires that the issue be resolved against [the
    appellant]’”].)
    D. Section 998 Offer
    Defries’s final contention is that the trial court’s costs award to Yamaha was in
    error because its earlier section 998 offer, made in October 2018, was invalid. Because
    we reverse the judgment as to the negligence cause of action, this issue is not yet ripe for
    review.
    The ripeness requirement “prevents courts from issuing purely advisory opinions.”
    (Pacific Legal Foundation v. California Coastal Com. (1982) 
    33 Cal.3d 158
    , 170.) “‘A
    controversy is “ripe” when it has reached, but has not passed, the point that the facts have
    43
    sufficiently congealed to permit an intelligent and useful decision to be made.’” (Id. at p.
    171.) As the matter now stands, any decision regarding the propriety of the section 998
    offer would have to assume both that there will be a new trial on the negligence cause of
    action and that Defries will not recover more than the amount stated in Yamaha’s section
    998 offer. (See Code of Civ. Proc, § 998, subd. (c)(1) [“If an offer made by a defendant
    is not accepted and the plaintiff fails to obtain a more favorable judgment or award, the
    plaintiff shall not recover his or her post offer costs and shall pay the defendant’s costs
    from the time of the offer”].) Neither of these assumptions would necessarily be true.
    Accordingly, we decline to rule on the issue now.
    III. DISPOSITION
    The judgment is reversed as to the cause of action for negligence and the award of
    costs. In all other respects, the judgment is affirmed. The parties shall bear their own
    costs on appeal.

    [Defries v. Yamaha Motor Corporation, U.S.A., E073917]
    MENETREZ, J., Concurring and Dissenting.
    The majority opinion holds that it can be a tort to sell a nondefective product.
    According to the majority opinion, if a distributor sells a partially unassembled product to
    a dealer and the dealer negligently assembles it, thereby rendering it dangerous, then the
    distributor is vicariously liable for the dealer’s negligence even if the product was in no
    way defective when it left the distributor’s hands—it was not defectively designed or
    manufactured, there was nothing wrong with selling it partially unassembled, there was
    nothing wrong with the assembly instructions, and so on. The distributor did nothing but
    sell a nondefective product, and yet the distributor is liable in tort. That is not and never
    has been the law.
    The majority opinion’s holding is based entirely on the California Supreme
    Court’s decision in Vandermark v. Ford Motor Co. (1964) 
    61 Cal.2d 256
     (Vandermark).
    In the 58 years since Vandermark was decided, not a single published opinion of any
    California appellate court has interpreted it in the manner adopted by the majority
    opinion. That is unsurprising, because Vandermark has nothing to do with holding a
    distributor liable for a dealer’s negligence. The jury in Vandermark found that the dealer
    was not negligent, and that finding was affirmed. (Id. at pp. 259, 263-264.) Thus, there
    was no dealer negligence for which another party could be held liable. The majority
    opinion discusses Vandermark for pages but never mentions that critical fact.
    1
    Putting aside the interpretation of Vandermark, the majority opinion’s partial
    reversal of the judgment is erroneous for an independent reason. The reversal is based on
    the trial court’s rejection of plaintiff’s request to instruct the jury with CACI No. 3713,
    which the majority opinion describes as “an instruction on nondelegable duty.” (Maj.
    opn., ante, at p. 7.) But CACI No. 3713 is an instruction concerning the liability of a
    principal for the negligence of an independent contractor. Because there was no
    principal-independent contractor relationship between the distributor and the dealer in
    this case, CACI No. 3713 does not apply.
    There is no basis to reverse the judgment even in part. I therefore respectfully
    dissent.
    1.     Background
    Plaintiff Chad Defries was injured in a crash while riding a motorcycle. Defries
    contends that the throttle assembly came off the right handlebar while he was riding,
    thereby causing him to crash.
    Defries’s wife bought the motorcycle for him from an authorized Yamaha dealer,
    West Coast Yamaha, Inc., dba Langston Motorsports (Langston). Langston had
    purchased the motorcycle from the manufacturer’s United States distributor, defendant
    Yamaha Motor Corporation, U.S.A. (Yamaha).
    Yamaha’s motorcycles (like other manufacturers’ motorcycles) are partially
    unassembled when they are shipped to the dealer. The dealer performs the final assembly
    before selling the motorcycle to the consumer. As part of the final assembly of Defries’s
    2
    motorcycle, Langston attached the throttle assembly to the handlebar. Defries contended
    that Langston performed that work negligently, improperly torquing the two bolts that
    secure the throttle assembly to the handlebar.
    Defries sued Langston, Yamaha, and other defendants on various theories. But he
    dismissed the other defendants and settled with Langston before trial, leaving Yamaha as
    the only defendant. The only claims that Defries pursued at trial were negligence, strict
    products liability for failure to warn, and breach of implied warranty. The jury returned a
    verdict in favor of Yamaha on all claims.
    Defries had asked the trial court to instruct the jury with CACI No. 3713. The
    bench notes for CACI No. 3713 explain the instruction’s applicability as follows: “Use
    this instruction with regard to the liability of the hirer for the torts of an independent
    contractor if a nondelegable duty is imposed on the hirer by statute, regulation, ordinance,
    contract, or common law.” Defries sought to use the instruction to hold Yamaha (the
    distributor) liable for the negligence of Langston (the dealer) in assembling the
    motorcycle.
    CACI No. 3713 contains numerous bracketed portions that must be filled in before
    the instruction can be used. In particular, the instruction states that the plaintiff must
    prove the following: “That [name of defendant] hired [name of independent contractor]
    to [describe job involving nondelegable duty, e.g., repair the roof].”
    3
    When Defries requested CACI No. 3713, he did not fill in any of the bracketed
    portions, and to this day he has never filled in any of them. The trial court declined to
    give the instruction to the jury.
    2.     A Distributor Is Not Liable for a Dealer’s Negligence
    The majority opinion holds that when a distributor sells a nondefective but
    partially unassembled product to a dealer and the dealer negligently assembles it, thereby
    rendering it dangerous, the distributor is vicariously liable for the dealer’s negligence.
    (Maj. opn., ante, at p. 2.) No such rule exists.
    Negligent assembly of a product would constitute a manufacturing defect. (See
    Barker v. Lull Engineering Co. (1978) 
    20 Cal.3d 413
    , 429 [defining manufacturing
    defects]; CACI No. 1202 [“A product contains a manufacturing defect if the product
    differs from the manufacturer’s design or specifications or from other typical units of the
    same product line”].) A defendant is liable for a manufacturing defect only if the product
    was defective when it left the defendant’s possession. (CACI No. 1201 [to hold a
    defendant liable for a manufacturing defect, the plaintiff must prove “[t]hat the [product]
    contained a manufacturing defect when it left [name of defendant]’s possession”]; see
    Hasson v. Ford Motor Co. (1982) 
    32 Cal.3d 388
    , 405-406 (Hasson).) Consequently, a
    distributor who sells a nondefective but partially unassembled product to a dealer is not
    liable for the dealer’s negligent assembly of the product.
    The same conclusion would follow if, for example, the motorcycle’s manufacturer
    purchased the motorcycle’s brake system from a third party. If the brake system was
    4
    nondefective but unassembled when delivered to the manufacturer, and the manufacturer
    negligently assembled it when incorporating it into the motorcycle, then the manufacturer
    of the motorcycle would be liable, but the third party producer of the brake system would
    not. (See Ramos v. Brenntag Specialties, Inc. (2016) 
    63 Cal.4th 500
    , 508 [if a component
    part is not defective, “‘it would be unjust and inefficient to impose liability’” on the
    producer of the component part “‘solely on the ground that the manufacturer of the
    integrated product utilizes the component in a manner that renders the integrated product
    defective’”]; Rest.3d Torts, Products Liability, § 5, com. a [sellers of component parts
    generally are not liable “when the component itself is not defective”].) It is not a tort to
    sell a nondefective product.
    The majority opinion derives its contrary conclusion entirely from a
    misinterpretation of Vandermark. But Vandermark cannot have held that a distributor is
    vicariously liable for a dealer’s negligence, because the dealer in Vandermark was not
    negligent.
    In Vandermark, both the driver of a Ford automobile and his passenger were
    injured in a crash. (Vandermark, supra, 61 Cal.2d at p. 258.) They sued the Ford Motor
    Company (Ford), “which manufactured and assembled the car,” and the authorized dealer
    that had sold the car to the driver, Maywood Bell Ford (Maywood Bell). (Ibid.) The suit
    alleged causes of action for breach of warranty and negligence against both defendants.
    (Ibid.) “The trial court granted Ford’s motion for a nonsuit on all causes of action and
    directed a verdict in favor of Maywood Bell on the warranty causes of action.” (Id. at pp.
    5
    258-259.) The jury returned a verdict in favor of Maywood Bell on the negligence claim,
    and the plaintiffs appealed. (Id. at p. 259.) The Supreme Court affirmed the judgment
    for Maywood Bell on the negligence claim, but it reversed the judgment in all other
    respects. (Id. at p. 264.)
    At trial, the plaintiffs had introduced expert testimony that the crash was caused by
    a problem with the brake system. (Vandermark, supra, 61 Cal.2d at pp. 259-260.) They
    also sought to introduce expert testimony concerning the possible causes of that problem,
    which included “a defective or wrong-sized part” and “improper assembly,” but the trial
    court erroneously struck that testimony. (Id. at p. 260.) Thus, the admitted evidence and
    the erroneously excluded evidence, taken together, showed that “the master cylinder
    assembly had a defect that caused the accident” and “that the defect was owing to
    negligence in design, manufacture, assembly, or adjustment.” (Ibid.) Because the
    plaintiffs thus had introduced or attempted to introduce substantial evidence of a defect
    caused by Ford’s own negligence in designing, manufacturing, and assembling the car,
    the trial court erred by granting nonsuit in Ford’s favor. (Id. at p. 261.)
    Ford sought to escape liability for its own negligence, however, on the ground that
    possible causes of the defect other than Ford’s negligence had not been affirmatively
    excluded. (Vandermark, supra, 61 Cal.2d at p. 260.) In support of that argument, Ford
    “point[ed] out that in this case the car passed through two other authorized Ford dealers
    before it was sold to Maywood Bell and that Maywood Bell removed the power steering
    unit before selling the car to Vandermark.” (Ibid.) Moreover, the role of such
    6
    intermediaries between Ford and the injured plaintiffs appeared to distinguish the case
    from the Supreme Court’s landmark decision in Greenman v. Yuba Power Products, Inc.
    (1963) 
    59 Cal.2d 57
     (Greenman). Greenman held that “[a] manufacturer is strictly liable
    in tort when an article he places on the market, knowing that it is to be used without
    inspection for defects, proves to have a defect that causes injury to a human being.” (Id.
    at p. 62, italics added.) Ford “relie[d] on its dealers to make the final inspections,
    corrections, and adjustments necessary to make the cars ready for use” (Vandermark, at
    p. 261), so the Greenman rule appeared inapplicable—Ford’s cars were inspected after
    they left Ford’s possession but before delivery to consumers.
    The Supreme Court rejected the argument. Having introduced (or sought to
    introduce) substantial evidence that the crash was caused by Ford’s negligence, the
    plaintiffs did not have to prove in addition that the crash was not caused by the
    negligence of an intermediary—Ford “cannot escape liability on the ground that the
    defect in Vandermark’s car may have been caused by something one of its authorized
    dealers did or failed to do.” (Vandermark, supra, 61 Cal.2d at p. 261, italics added.)
    That is, given the substantial evidence that plaintiffs’ injuries were caused by Ford’s
    negligence, the mere possibility that an intermediary had done something that caused the
    crash—which plaintiffs’ evidence did not affirmatively rule out—was not sufficient to
    insulate Ford from liability.
    The majority opinion interprets the Supreme Court’s language—Ford “cannot
    escape liability on the ground that the defect in Vandermark’s car may have been caused
    7
    by something one of its authorized dealers did or failed to do” (Vandermark, supra, 61
    Cal.2d at p. 261)—as meaning that Ford is vicariously liable for its dealers’ negligence.
    (Maj. opn., ante, at pp. 13-14.) But that cannot be what the Supreme Court meant,
    because the dealer was not negligent. (Elisa B. v. Superior Court (2005) 
    37 Cal.4th 108
    ,
    118 [the court’s language “‘in any opinion is of course to be understood in the light of the
    facts and the issue then before the court’”].) The jury rejected the negligence claim
    against Maywood Bell, and the Supreme Court affirmed that part of the judgment.
    (Vandermark, at pp. 263-264.) (There was no evidence that the other intermediaries had
    done anything, negligent or otherwise, that might have caused the defect.) Thus, when
    Ford argued that the role of the dealer showed that Ford “may not be held liable for
    negligence in manufacturing the car or strictly liable in tort for placing it on the market”
    (id. at p. 260), Ford was not arguing (and could not have been arguing) against being held
    vicariously liable for the dealer’s negligence. There was no such negligence. Ford was
    arguing only that because the dealer’s possible contribution to the causation of the
    accident had not been disproved, Ford could not be held liable for its own negligence.
    That is the argument that the Supreme Court rejected: Ford “cannot escape liability on
    the ground that the defect in Vandermark’s car may have been caused by something one
    of its authorized dealers did or failed to do.” (Vandermark, at p. 261.)
    Moreover, even if it were true that the Supreme Court in Vandermark stated that
    Ford was vicariously liable for Maywood Bell’s negligence, any such statement would be
    dicta, because the Supreme Court affirmed the finding that Maywood Bell was not
    8
    negligent. “An appellate decision is not authority for everything said in the court’s
    opinion but only ‘for the points actually involved and actually decided.’” (Santisas v.
    Goodin (1998) 
    17 Cal.4th 599
    , 620; see Brown v. Kelly Broadcasting Co. (1989) 
    48 Cal.3d 711
    , 734-735.) Dicta, or “‘observations and statements unnecessary to the
    appellate court’s resolution of the case’” (Sonic-Calabasas A, Inc. v. Moreno (2013) 
    57 Cal.4th 1109
    , 1158), have no “binding precedential effect.” (ABC Internat. Traders, Inc.
    v. Matsushita Electric Corp. (1997) 
    14 Cal.4th 1247
    , 1265.)
    The majority opinion also attempts to portray this case and Vandermark as
    “nondelegable duty” cases like Dow v. Holly Mfg. Co. (1958) 
    49 Cal.2d 720
     (Dow),
    which held that a general contractor is vicariously liable for the negligence of a
    subcontractor (id. at p. 725). (Maj. opn., ante, at pp. 10-13.) Again, the majority opinion
    is mistaken. It is true that Vandermark includes a citation to Dow and also states that
    Ford “cannot delegate its duty to have its cars delivered to the ultimate purchaser free
    from dangerous defects.” (Vandermark, supra, 61 Cal.2d at p. 261.) But Vandermark is
    a products liability case, and the nondelegable duty doctrine at issue in Dow is not a
    products liability doctrine. Rather, it is an exception to the general rule that a principal is
    not vicariously liable for the negligence of an independent contractor—if the principal
    owes a nondelegable duty to the injured party, then the principal is liable for the
    independent contractor’s negligence. (See, e.g., Van Arsdale v. Hollinger (1968) 
    68 Cal.2d 245
    , 250-251 (Van Arsdale); Maloney v. Rath (1968) 
    69 Cal.2d 442
    , 446-447
    (Maloney).) There is no principal-independent contractor relationship between Yamaha
    9
    and Langston. Dow and the nondelegable duty doctrine consequently have nothing to do
    with this case.
    Before today, no published opinion has ever cited Vandermark as a nondelegable
    duty case. Moreover, just four years after Vandermark, the Supreme Court decided two
    cases concerning nondelegable duty. Both opinions discussed the doctrine extensively,
    but neither opinion mentioned Vandermark. (Van Arsdale, supra, 68 Cal.2d at pp. 245-
    257; Maloney, supra, 69 Cal.2d at pp. 442-448.) Maloney described the “wide variety of
    situations” in which nondelegable duties have been recognized, citing more than a dozen
    cases (including Dow), but Vandermark was not among them. (Maloney, at p. 447.)
    Until now, no one has ever thought that Vandermark was a nondelegable duty case, and it
    clearly is not. It is a products liability case, not a case about the vicarious liability of a
    principal for the negligence of an independent contractor. And again, even if there were
    a principal-independent contractor relationship between Ford and Maywood Bell (which
    there was not), Vandermark still could not be about holding a principal liable for an
    independent contractor’s negligence, because Maywood Bell was not negligent.
    It is true that a manufacturer’s duty to produce a nondefective product is
    nondelegable in various respects. For example, if a third party supplier produces a
    defective component that a manufacturer incorporates into a larger product, thereby
    rendering the larger product defective, then the manufacturer cannot escape liability on
    the ground that the third party, rather than the manufacturer, caused the defect. (O’Neil v.
    Crane Co. (2012) 
    53 Cal.4th 335
    , 348, citing Vandermark [“Strict liability encompasses
    10
    all injuries caused by a defective product, even those traceable to a defective component
    part that was supplied by another”].) Similarly, a manufacturer that produces a defective
    product cannot escape liability on the ground that downstream entities were supposed to
    inspect the product (as in Vandermark) or even on the ground that information about the
    defect was communicated to downstream entities by means of a recall notice (Ford
    Motor Co. v. Robert J. Poeschl, Inc. (1971) 
    21 Cal.App.3d 694
    , 698-699). In all of those
    ways, the manufacturer’s duty to produce a nondefective product is nondelegable.
    Similar points would apply to the duty of a distributor. But none of that has anything to
    do with vicarious liability or with holding an upstream party liable for the negligence of a
    downstream party. Rather, it is about preventing the manufacturer (or distributor) from
    escaping liability for a product that was already defective when it left the manufacturer’s
    (or distributor’s) possession.
    Thus, a manufacturer or distributor’s nondelegable duty to produce or sell a
    nondefective product is fully discharged if the product is nondefective when it leaves the
    manufacturer’s or distributor’s possession. There is simply no legal basis for the majority
    opinion’s contrary conclusion.
    The majority opinion attempts to bolster its misinterpretation of Vandermark by
    quoting out of context a single sentence from the Restatement Third of Torts, Products
    Liability (Restatement). (Maj. opn., ante, at p. 20.) The attempt fails, because the
    majority opinion misinterprets the Restatement as well.
    11
    According to the Restatement, “[o]ne engaged in the business of selling or
    otherwise distributing products who sells or distributes a defective product is subject to
    liability for harm to persons or property caused by the defect.” (Rest.3d Torts, Products
    Liability, § 1.) The Restatement further provides that “[a] product is defective when, at
    the time of sale or distribution, it contains a manufacturing defect, is defective in design,
    or is defective because of inadequate instructions or warnings.” (Id., § 2, italics added.)
    A product “contains a manufacturing defect when the product departs from its intended
    design . . . .” (Id., § 2(a).)
    Taken together, those provisions mean that a manufacturer or distributor is liable
    for injuries caused by a defectively assembled product if the product was already
    defectively assembled when it left the manufacturer’s or distributor’s possession. The
    Restatement’s comments make that clear: “Common examples of manufacturing defects
    are products that are physically flawed, damaged, or incorrectly assembled. In actions
    against the manufacturer, under prevailing rules concerning allocation of burdens of
    proof the plaintiff ordinarily bears the burden of establishing that such a defect existed in
    the product when it left the hands of the manufacturer.” (Rest.3d Torts, Products
    Liability, § 2, com. c, italics added.)
    The ensuing comments expand on the point: “Occasionally a defect may arise
    after manufacture, for example, during shipment or while in storage. Since the product,
    as sold to the consumer, has a defect that is a departure from the product unit’s design
    specifications, a commercial seller or distributor down the chain of distribution is liable
    12
    as if the product were defectively manufactured. As long as the plaintiff establishes that
    the product was defective when it left the hands of a given seller in the distributive chain,
    liability will attach to that seller.” (Rest.3d Torts, Products Liability, § 2, com. c, italics
    added.) That is, a departure from the product’s design is classified as a “manufacturing
    defect” even if it arises after the product leaves the manufacturer’s possession, but a
    seller ordinarily is liable for such a defect only if the defect already existed when the
    product left the seller’s possession. Consequently, manufacturers are not, in general,
    liable for such defects.
    The Restatement’s rules and comments thus establish that if a product is not
    defective when it leaves the hands of a given seller, then the seller ordinarily will not be
    liable for a defect that arises later. If sellers were ordinarily liable for such defects, then
    the Restatement’s repeated references to defects existing when the product leaves the
    seller’s possession would be superfluous.
    At the same time, it is not impossible for a seller to be liable for a defect that is
    created after the product leaves the seller’s possession. In a particular case, there might
    be a basis to impose such liability. The Restatement’s comments acknowledge that
    possibility too: “When the manufacturer delegates some aspect of manufacture, such as
    final assembly or inspection, to a subsequent seller, the manufacturer may be subject to
    liability under rules of vicarious liability for a defect that was introduced into the product
    after it left the hands of the manufacturer.” (Rest.3d Torts, Products Liability, § 2,
    com. c, italics added.) That is, the manufacturer may or may not be liable, depending
    13
    upon whether there is an applicable rule of vicarious liability (such as respondeat
    superior).
    The majority opinion asserts that its holding is “in accord” with the Restatement’s
    comment concerning liability for a defect that is created after the product leaves the
    seller’s hands. (Maj. opn., ante, at p. 20.) To a limited extent, that is true—the majority
    opinion holds Yamaha liable for a defect that was created after the motorcycle left
    Yamaha’s possession, and the Restatement does not state that such liability is
    categorically impossible. But in every other way, the majority opinion conflicts with the
    Restatement. According to the majority opinion, a distributor like Yamaha is always
    liable for a defect introduced by a downstream seller like Langston, with no need for
    further analysis. (See, e.g., maj. opn., ante, at p. 2 [“if the dealer negligently assembled
    the product, Yamaha was jointly liable for damages caused by that negligence”].) The
    Restatement, in contrast, says only that an upstream party may be liable for a defect
    introduced by a downstream party, depending upon whether there is an applicable rule of
    vicarious liability. The majority opinion does not identify any such rule. And according
    to the majority opinion, the distinction between defects existing before the product leaves
    the seller’s possession and defects created later is of no significance—the seller’s
    nondelegable duty automatically renders the seller liable for all of them. But according
    to the Restatement, the timing is pivotal—the seller is liable for defects that existed when
    the product left the seller’s possession, but the seller merely may be liable for later-
    created defects, if there is an applicable principle of vicarious liability.
    14
    In all of these ways, the Restatement provides no support for the majority opinion
    and actually conflicts with it. As the Restatement confirms, there is no basis in products
    liability law to hold Yamaha liable for Langston’s negligent assembly of the motorcycle.
    And the majority opinion does not identify any rule of vicarious liability that would make
    Yamaha liable, so, according to the Restatement, Yamaha is not liable.
    Finally, the majority opinion’s interpretation of Vandermark is completely
    ahistorical. Before the dramatic developments in California products liability law in the
    1960s, in general the manufacturer of a product that injured a consumer was not liable
    without privity of contract. That is, a manufacturer generally was not liable even for its
    own negligence unless there was contractual privity between the manufacturer and the
    injured party. (See generally Cotchett & Cartwright, Cal. Products Liability Actions
    (2022) § 1.01 (Cotchett & Cartwright).) The California Supreme Court abolished the
    privity requirement in Greenman, holding that “[a] manufacturer is strictly liable in tort
    when an article he places on the market, knowing that it is to be used without inspection
    for defects, proves to have a defect that causes injury to a human being.” (Greenman,
    supra, 59 Cal.2d at p. 62.)
    Greenman was decided in 1963. Its major innovation was the imposition of strict
    tort liability on a manufacturer in the absence of contractual privity with the injured
    purchaser. (Cotchett & Cartwright, supra, § 1.03.) Vandermark was decided in 1964.
    Its major innovations were the imposition of strict tort liability on a retailer for selling a
    defective product and the extension of such liability to injured parties other than the
    15
    actual purchaser (one of the plaintiffs was a passenger with no ownership interest in the
    car). (Cotchett & Cartwright, at § 1.03.)
    If the majority opinion were right that Vandermark held that a manufacturer is
    liable for a dealer’s negligence, then that holding would have been a bombshell. Just one
    year after revolutionizing products liability law by holding manufacturers liable for their
    own negligence without contractual privity, the Supreme Court would, on the majority
    opinion’s interpretation, have held manufacturers strictly liable for the negligence of
    retailers who were not the manufacturers’ employees or even their independent
    contractors. Reactions to that holding—both positive and negative—would have been
    swift, shrill, and numerous, and case after case would have cited Vandermark for the
    remarkable proposition that selling a nondefective product can be a tort. But there was
    no such reaction, and no published California appellate decision before today has cited
    Vandermark for the proposition that a manufacturer or distributor who sells a
    nondefective product is vicariously liable for a retailer’s negligence.
    The majority opinion claims that Vandermark’s alleged holding—that a
    manufacturer is liable for a dealer’s negligence—actually was recognized as a bombshell
    in Prosser, The Fall of the Citadel (Strict Liability to the Consumer) (1966) 50 Minn.
    L.Rev. 791 (Prosser). (Maj. opn., ante, at pp. 20-21, fn. 5.) The majority opinion also
    cites Leebron, An Introduction to Products Liability: Origins, Issues, and Trends (1990)
    Ann.Surv.Amer.L. 395 (Leebron) in support of its interpretation. (Maj. opn., ante, at
    16
    p. 21, fn. 5.) The majority opinion is again mistaken, because Prosser’s and Leebron’s
    interpretations of Vandermark are the same as mine.
    Prosser cites Vandermark for the proposition that “the maker of an automobile
    with a defective steering gear, or a leak in the hydraulic brake line, can scarcely expect to
    be relieved of his responsibility by reason of the fact that the car is sold to a dealer who is
    expected to service it, adjust the brakes, mount the tires, and the like, before it is ready
    for use.” (Prosser, supra, 50 Minn. L.Rev. at pp. 806-807 & fn. 90.) Prosser thus
    understands Vandermark as rejecting the manufacturer’s attempt to evade liability for its
    own defective product, not as holding the manufacturer liable for the dealer’s negligence.
    Similarly, Leebron cites Vandermark for the proposition that “courts early on
    rejected attempts by automobile manufacturers to avoid strict liability by delegating final
    tasks, such as inspection of the brakes, to dealers.” (Leebron, supra, Ann.Surv.Amer.L.
    395 at p. 424.) That is, the dealer’s duty to inspect the brakes does not cut off the
    manufacturer’s liability for having produced a car with defective brakes. Again, none of
    that has anything to do with holding a manufacturer liable for a dealer’s negligence.
    Prosser characterized Vandermark as “extreme” not because it held a manufacturer
    liable for a dealer’s (nonexistent) negligence but because it took such an extreme position
    concerning the conduct of intermediaries between the defective product’s manufacturer
    and the injured plaintiff. (Prosser, supra, 50 Minn. L.Rev. at pp. 826-828.) The relevant
    passage occurs in a section of the article entitled “Intervening Conduct,” which discusses
    the circumstances in which the seller of a defective product might escape liability
    17
    because of the conduct of a third party who intervenes between the seller and the injured
    plaintiff. (Id. at pp. 826-828.) The article explains, for example, that “the failure of the
    dealer, or some other intermediate party, to discover the defect on the product, or any
    other negligent conduct on his part, or indeed on the part of anyone else, which is found
    reasonably to be anticipated, will not relieve the earlier supplier of liability.” (Id. at
    pp. 826-827, fns. omitted, italics added.) Thus, if the product was already defective when
    it left the earlier seller’s possession, then the dealer’s failure to discover the defect will
    not relieve the earlier seller of liability.
    But the article goes on to distinguish situations in which intervening conduct
    might cut off the manufacturer’s liability, such as “where the intermediate party is
    notified of the danger, or discovers it for himself, and proceeds de[li]berately to ignore it
    and to pass on the product without a warning.” (Prosser, supra, 50 Minn. L.Rev. at
    p. 827, fns. omitted.) The discussion then turns to Vandermark, which is “the most
    extreme decision” in this area because it states that the dealer’s intervention does not cut
    off the manufacturer’s liability no matter what the dealer “‘did or failed to do.’” (Id. at
    pp. 827-828.) The article concludes by observing that it is not yet clear how Vandermark
    will be interpreted and applied, such as “whether the decision would be the same if the
    dealer discovered the danger and sold the car deliberately with no attempt to remedy it.”
    (Id. at p. 828, italics added.) That is, it “is not yet determined” whether the manufacturer
    would be liable if (1) the car was already defective when it left the manufacturer, and (2)
    the dealer discovered the defect but sold the car without even trying to fix it. (Ibid.) Yet
    18
    again, none of that has anything to do with holding a manufacturer liable for a dealer’s
    negligence. It is about holding a manufacturer liable for a product that was defective
    when it left the manufacturer’s possession, and not letting the manufacturer escape
    liability on the basis of a subsequent act or omission by a downstream seller.
    The majority opinion’s reliance on Prosser is therefore misplaced. Prosser
    interprets Vandermark the same way I do. And Prosser did not describe the majority
    opinion’s rule—that a manufacturer is liable for a dealer’s negligence—as extreme or a
    bombshell, because Prosser did not find any such rule in Vandermark.
    There is one additional oddity about the majority opinion that is worth noting.
    The majority opinion purports to apply an uncontroversial, well-settled theory of tort
    liability that has existed at least since the Supreme Court decided Vandermark in 1964.
    But there is no pattern jury instruction on the majority opinion’s theory. CACI contains
    extensive instructions on theories of products liability, negligence, and vicarious liability
    (see CACI Nos. 400-473, 1200-1249, 3700-3727), but the majority opinion’s theory is
    not among them. If such a useful and well-established rule of tort liability really existed,
    then it would be hard to understand why in the last 58 years no one ever saw the need to
    draft a pattern instruction to explain it to a jury.
    For all of the foregoing reasons, I disagree with the majority opinion’s holding that
    when a distributor sells a nondefective but partially unassembled product to a dealer and
    the dealer negligently assembles it, thereby rendering it dangerous, the distributor is
    19
    vicariously liable for the dealer’s negligence. That holding is erroneous, and neither
    Vandermark nor any other California authority supports it.
    3.     A Distributor-Dealer Relationship Is Not a Principal-Independent Contractor
    Relationship, so CACI No. 3713 Does Not Apply
    The majority opinion’s partial reversal of the judgment is based on instructional
    error. (Maj. opn., ante, at pp. 7, 20.) The putative error was the trial court’s rejection of
    Defries’s request to instruct the jury with CACI No. 3713. The trial court’s ruling was
    correct, because CACI No. 3713 does not apply to this case.
    The bench notes for CACI No. 3713 explain that the instruction is to be used “with
    regard to the liability of the hirer for the torts of an independent contractor if a
    nondelegable duty is imposed on the hirer by statute, regulation, ordinance, contract, or
    common law.” “An independent contractor is a person who contracts with another to do
    something for [them] but who is not controlled by the other nor subject to the other’s
    right to control with respect to [the independent contractor’s] physical conduct in the
    performance of the undertaking.” (Rest.2d Agency, § 2, subd. (3).)
    Defries does not argue that Langston contracted with Yamaha to assemble the
    motorcycle that was eventually purchased by Defries’s wife. Langston bought the
    partially unassembled motorcycle from Yamaha. As to that motorcycle, Langston and
    Yamaha’s contractual obligations to each other were satisfied once Langston paid
    Yamaha and Yamaha delivered the motorcycle to Langston. Because Yamaha did not
    hire Langston to assemble the motorcycle (or to do anything else, as far as the evidence
    20
    shows), Langston was not Yamaha’s independent contractor. CACI No. 3713 therefore
    does not apply, and the trial court correctly rejected Defries’s request for it.
    The terms of CACI No. 3713 confirm that there is no way to apply it in this case.
    The instruction provides that the plaintiff must prove “[t]hat [name of defendant] hired
    [name of independent contractor] to [describe job involving nondelegable duty, e.g.,
    repair the roof].” Because Yamaha did not hire Langston to do anything, it is impossible
    to complete the third bracketed portion of the instruction. Neither Defries nor the
    majority opinion has explained how it is to be done. The majority opinion concedes that
    certain bracketed portions in CACI No. 3713 “might have been difficult to fill in” (maj.
    opn., ante, at p. 20) but does not mention this one. The upshot is that the judgment is
    being reversed for failure to give a particular jury instruction, but no one knows what the
    instruction is supposed to say.
    For the foregoing reasons, the trial court did not err by declining to instruct the
    jury with CACI No. 3713. Yamaha did not hire Langston to do anything, Langston is not
    Yamaha’s independent contractor, and CACI No. 3713 consequently has nothing to do
    with this case.
    4.     Conclusion
    The majority opinion creates a sweeping new rule of tort liability that has no basis
    in California law. The majority opinion purports to find that rule in Vandermark, where
    it has escaped the notice of every lawyer and judge in California for the last 58 years.
    And the damage that the majority opinion thereby does to California law is wholly
    21
    gratuitous, because even if the majority opinion were right about Vandermark, we should
    not reach the issue, because the only requested instruction on it, CACI No. 3713, is
    clearly inapplicable.
    The trial court’s judgment should therefore be affirmed in its entirety.
    Accordingly, I respectfully dissent from the portions of the majority opinion and
    judgment that partially reverse, and I otherwise concur.
