Directions for Use
This cause of action could also apply to products that are leased. If so, modify the
instruction accordingly.
The giving of notice to the seller is not required in personal injury or property
damage lawsuits against a manufacturer or another supplier with whom the plaintiff
has not directly dealt. (Greenman v. Yuba Power Products, Inc. (1963) 59 Cal.2d 57,
61 [27 Cal.Rptr. 697, 377 P.2d 897]; Gherna v. Ford Motor Co. (1966) 246
Cal.App.2d 639, 652-653 [55 Cal.Rptr. 94].)
If an instruction on the giving of notice to the seller is needed, see CACI No. 1243,

“Unlike express warranties, which are basically contractual in nature, the implied
warranty of merchantability arises by operation of law. 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 [44 Cal.Rptr.2d
526], internal citations omitted.)
“[I]n cases involving personal injuries resulting from defective products, the
theory of strict liability in tort has virtually superseded the concept of implied
warranties.” (Grinnell v. Charles Pfizer & Co. (1969) 274 Cal.App.2d 424, 432
[79 Cal.Rptr. 369].)
“Vertical privity is a prerequisite in California for recovery on a theory of breach
of the implied warranties of fitness and merchantability.” (United States Roofing,
Inc. v. Credit Alliance Corp. (1991) 228 Cal.App.3d 1431, 1441 [279 Cal.Rptr.
533], internal citations omitted.)
“[Plaintiff] comes within a well-recognized exception to the [privity] rule: he is a
member of the purchasers family.” (Hauter v. Zogarts (1975) 14 Cal.3d 104,
115, fn. 8 [120 Cal.Rptr. 681, 534 P.2d 377].)
“Therefore, says plaintiff, . . . in view of modern industrial usage employe[e]s
should be considered a member of the industrial ‘family’ of the
employer - whether corporate or private - and to thus stand in such privity to the
manufacturer as to permit the employe[e]s to be covered by warranties made to
the purchaser-employer. [¶] We are persuaded that this position is meritorious.”
(Peterson v. Lamb Rubber Co. (1960) 54 Cal.2d 339, 347 [5 Cal.Rptr. 863, 353
P.2d 575].)
“A buyer who is damaged by a breach of implied warranty has two possible
measures of those damages: one where the buyer has rightfully rejected or
‘justifiably revoked acceptance’ of the goods, and one where the buyer has
accepted the goods.” (Simgel Co., Inc. v. Jaguar Land Rover North America,
LLC (2020) 55 Cal.App.5th 305, 315-316 [269 Cal.Rptr.3d 364].)
