Defries v. Yamaha Motor Corporation, U.S.A.Annotate this Case
Plaintiff-appellant Chad Defries suffered injuries while riding a Yamaha dirt bike. He sued the U.S. distributor of that dirt bike, defendant-respondent Yamaha Motor Corporation, U.S.A. (Yamaha), among others, asserting that the accident was 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 contended, among other things, that the trial 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. The Court of Appeal found that California law, however, placed “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.” The same principle applied 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.” 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, the Court of Appeal reversed the judgment on the negligence cause of action, and affirmed in all other respects.
