California Product Liability: Hold Makers Accountable

What Is Product Liability in California?

Product liability holds companies responsible when defective or dangerously designed products cause injuries. In California, responsibility can reach across the supply chain—manufacturers, component makers, distributors, and retailers. Claims may proceed under strict liability, negligence, and warranty theories, depending on the facts. California adopted strict products liability in Greenman v. Yuba Power Products, Inc., 59 Cal.2d 57.

Strict Liability: The Core Framework

Under strict liability, an injured person does not have to prove the company was careless; the focus is on whether the product was defective and whether that defect caused the injury. California recognizes three principal defect types: design defects, manufacturing defects, and inadequate warnings or instructions. See Barker v. Lull Engineering Co., 20 Cal.3d 413 and Anderson v. Owens-Corning Fiberglas Corp., 53 Cal.3d 987.

Design Defects: Consumer Expectations and Risk-benefit

For design defects, California recognizes two primary tests:

• Consumer expectations test: Did the product perform as safely as an ordinary consumer would expect when used in a reasonably foreseeable way?
• Risk-benefit test: Do the design’s benefits outweigh its risks, considering factors such as the feasibility of safer alternatives? Once the plaintiff makes a prima facie showing of causation, the burden can shift to the defendant to prove the design’s benefits outweigh the risks.

Courts may apply one or both tests depending on the product and evidence. See Barker and Soule v. General Motors Corp., 8 Cal.4th 548.

Manufacturing Defects: When Something Goes Wrong in Production

A manufacturing defect exists when a product departs from its intended design, making it more dangerous than expected. Proof commonly involves showing the particular item differed from the design or other identical units due to a production flaw and that the defect caused the injury. See Greenman.

Failure to Warn: Warnings and Instructions Matter

Manufacturers and sellers must provide adequate warnings and instructions about non-obvious risks and safe use. A product can be defective if reasonable warnings or instructions were missing, unclear, or insufficient, and that failure contributed to the harm. California recognizes strict liability for failure-to-warn defects. See Anderson v. Owens-Corning Fiberglas Corp., 53 Cal.3d 987.

Negligence and Warranty Claims

Beyond strict liability, you may assert negligence (for example, careless design, testing, or manufacturing, or failure to provide appropriate post-sale warnings) and breach of warranty (express or implied). These theories can offer additional avenues for recovery and different proof requirements.

What You Must Generally Prove

While each theory has unique elements, product cases typically require showing that the product was defective; the defect existed when it left the defendant’s control; you used the product in a reasonably foreseeable way; the defect was a substantial factor in causing injury; and you suffered damages such as medical costs, lost income, or pain and suffering.

Evidence That Strengthens Your Case

Helpful evidence can include the product itself and all parts or packaging; photos or videos of the incident and injuries; purchase records and serial numbers; manuals and warning labels; maintenance or repair records; recall notices or safety bulletins; expert inspections and testing; and medical records documenting injuries and causation.

Common Defenses You May Face

Defendants often argue misuse beyond foreseeable use, substantial product alteration after sale, assumption of risk, or that another cause—not a defect—led to the injury. Preservation of the product and prompt expert evaluation can be critical to counter these defenses.

Who Can Be Held Responsible

California’s approach can encompass manufacturers, component suppliers, distributors, and retailers in the product’s chain of distribution. Retailers and distributors may be strictly liable even if they did not create the defect. See Vandermark v. Ford Motor Co., 61 Cal.2d 256. Component manufacturers can be liable when the component itself is defective. See Jimenez v. Superior Court, 29 Cal.4th 473.

Compensation You May Seek

Available damages may include medical expenses, lost wages or earning capacity, property damage, and pain and suffering. In limited cases, punitive damages may be available where a defendant’s conduct involves malice, oppression, or fraud. See Cal. Civ. Code § 3294.

Act Promptly to Protect Your Rights

Product liability claims are subject to filing deadlines that can vary based on the type of claim, the nature of the injury, and when you discovered or reasonably should have discovered the harm. Acting quickly helps preserve evidence and ensures you meet applicable deadlines.

Practical Steps After a Product Injury

• Seek medical care and follow treatment plans.
• Preserve the product, parts, packaging, and receipts; avoid repairs or alterations.
• Photograph the scene, product, and injuries; note serial or model information.
• Save manuals, warning labels, and purchase records.
• Document communications with sellers or manufacturers.
• Consult a California product liability attorney as soon as possible.

FAQs

How long do I have to file a product liability claim in California?

Deadlines vary by claim type and discovery of injury. Speak with a lawyer promptly to identify the applicable statute of limitations and preserve your rights.

Do I need the original receipt or packaging?

They help but are not always required. Other proof of purchase, product identifiers, or witness testimony may suffice.

Can I sue the retailer even if they did not make the product?

Yes. California may hold retailers and distributors strictly liable as part of the chain of distribution.

What if I did not use the product exactly as instructed?

Reasonably foreseeable use is the key. Non-foreseeable misuse can be a defense; consult counsel about your specific facts.
