California Defective Product Lawyer: Claims and Liability

A design defect concerns the safety of a product's intended design rather than a deviation affecting only a particular manufactured unit. Courts apply the consumer expectations test to evaluate whether a product performed as safely as an ordinary consumer would expect when used in an intended or reasonably foreseeable manner. When ordinary consumer expectations do not provide an appropriate safety measure, the risk-benefit test may apply instead.

A manufacturing defect occurs when an individual item deviates from its intended design due to an error during assembly. Unlike design flaws, a manufacturing defect affects specific units rather than the whole product line. Plaintiffs generally must show that the product differed from its intended design and that the defect was a substantial factor in causing harm.

A failure-to-warn claim may arise when a product presents known or knowable risks that are not adequately disclosed to users. Manufacturers must warn about known or knowable risks when the applicable requirements for a duty to warn are satisfied. Liability also requires a sufficient causal connection between the inadequate warning and the plaintiff's resulting harm.

Strict liability shifts the focus from ordinary negligence principles to the product defect and the elements required for that particular claim. Plaintiffs generally must establish a qualifying defect, the defendant's connection to the product, and a causal link between the defect and the resulting harm. The analysis instead focuses on the alleged product defect and the elements of the applicable strict liability theory.

California strict liability can extend to qualifying manufacturers, distributors, and retailers within the commercial chain of distribution. Potential defendants may include manufacturers, distributors, retailers, or component suppliers when the applicable requirements for liability are satisfied. Liability for each defendant depends on its role in the distribution chain and the legal theory asserted.

The general statute of limitations for personal injury from a defective product is two years from the date of injury under California Code of Civil Procedure Section 335.1. However, the discovery rule may delay accrual when the plaintiff did not know, and could not reasonably have discovered, the injury and its wrongful cause. The applicable filing period therefore depends on when the claim accrued under the circumstances.

Express or implied warranty claims operate under different statutory periods than personal injury tort actions. California Commercial Code warranty claims generally carry a four-year limitations period, although accrual rules and statutory exceptions may affect the deadline. A warranty claim has separate elements and accrual rules, so an expired tort claim does not establish that a warranty remedy remains timely.

Economic damages may include quantifiable losses, such as past and future medical expenses, property damage, and lost income resulting from the injury. Non-economic damages compensate for subjective losses, such as physical pain, mental suffering, emotional distress, and loss of enjoyment of life.

California Civil Code Section 3294 permits punitive damages in qualifying noncontract actions when the statutory evidentiary requirements are satisfied. To qualify, plaintiffs must prove by clear and convincing evidence that the defendant acted with malice, oppression, or fraud. Evidence of intentional concealment of known product hazards may be relevant to whether the statutory standard for punitive damages is satisfied.

California follows a pure comparative negligence system. If a consumer misused a product or shared partial fault for an accident, the claim is not automatically barred. Instead, the court reduces the overall damages award by the percentage of fault assigned to the injured party.

Building a claim requires preserving the physical product in its post-incident state without alterations. Key evidence includes purchase receipts, maintenance records, medical documentation, and expert analysis of the product defect. Prior similar complaints may be relevant to notice when they concern substantially similar products, hazards, or circumstances.
