When a product fails and someone gets hurt — a power tool that throws a piece of wood, a vehicle part that fails, a medical device that breaks, a household appliance that catches fire — California law treats those injuries differently from an ordinary accident. In many of these cases, the injured person does not have to prove that the company was careless. They only have to prove the product was defective and that the defect caused the harm. This page explains, in plain English, how California's strict product liability rule works, the three kinds of product defects, who can be held responsible along the chain of distribution, what an injured person generally has to show, and the deadline for filing. Hurt Advice is not a law firm and does not provide legal advice — this is general information, every case is different, and you should talk to a licensed California attorney about your situation.

Under strict product liability, a company can be held responsible for a defective product even if it was not negligent and used reasonable care.
California recognizes three kinds of product defects: manufacturing defects, design defects, and warning or marketing defects (failure to warn).
You are not limited to suing the manufacturer — strict liability can reach distributors, wholesalers, and the retailer that sold the product.
Strict liability lowers the bar versus a negligence case, but it is not automatic — you still must show a defect that was a substantial factor in causing harm.
The general deadline for a personal injury from a defective product is two years from the date of injury under Code of Civil Procedure section 335.1, though the discovery rule and other exceptions can change that.
Whether a product is legally defective depends on facts and expert analysis — confirm your situation with a licensed California attorney.
Step-by-step
These steps are ordered for usefulness: safety and records first, then insurance, medical, and review decisions.
If you are not sure you have a case at all, start with the Do I Have a Case? quiz to get oriented before going further.
Consider whether your injury points to a manufacturing defect (this unit came out wrong), a design defect (the design itself is unsafe), or a warning defect (inadequate warnings or instructions).
Write down who made, distributed, and sold the product. Strict liability can reach sellers and others in the chain, not only the manufacturer — which matters if the maker is overseas or out of business.
Keep the product, packaging, receipts, and any instructions or warnings. Defective-product cases often turn on technical facts and expert analysis of the actual item.
Personal injury from a defective product is generally two years from the date of injury under CCP section 335.1, but exceptions and the discovery rule apply. Run the California Statute of Limitations calculator and do not guess.
Which parties to name and whether a product is legally defective are fact- and law-intensive questions. Request a free case review or find a lawyer in the directory.
The core rule
In a typical injury case — say a car crash — the injured person usually has to prove the other party was negligent (careless). Product cases work differently. California allows injured people to sue product makers and sellers under a doctrine called strict product liability, which means a company can be held responsible for a defective product even if it was not negligent and used reasonable care. This rule comes from a landmark California Supreme Court decision, Greenman v. Yuba Power Products, Inc. (1963) 59 Cal.2d 57. A man was seriously hurt when a piece of wood flew out of a combination power tool he was using as a lathe. The court held that a manufacturer is strictly liable in tort when an article it places on the market, knowing that it is to be used without inspection for defects, proves to have a defect that causes injury. California was a national pioneer of this doctrine. The practical point: in a product case you generally focus on the product, not on whether a specific employee made a mistake. Today, California juries are guided through the Judicial Council of California Civil Jury Instructions (CACI), No. 1200 and the related 1200-series instructions. These are general legal points to confirm with a licensed California attorney.
Defect categories
California recognizes three ways a product can be legally defective, and a claim can rest on one or more of them. A manufacturing defect means the specific product that hurt you came out wrong — it differs from the manufacturer's own design or specifications, or from other apparently identical units off the same line; the design may be fine, but this one unit was flawed (a cracked weld, a missing part, contaminated material). A design defect means the product was built as intended, but the design itself is unsafe, so every unit shares the danger. California uses two alternative tests for design defect, and an injured person can rely on either: the consumer expectation test (the product did not perform as safely as an ordinary consumer would expect when used or misused in an intended or reasonably foreseeable way) and the risk-benefit test (the benefits of the challenged design do not outweigh the risks built into it; once the injured person shows the design was a substantial factor in causing harm, the burden can shift to the company to prove the benefits outweigh the risks). A warning or marketing defect (failure to warn) means the product lacked adequate warnings or instructions about a danger that was known or knowable, so users were not told how to use it safely or what risks to avoid. The exact tests and definitions are technical — confirm them with a licensed California attorney.
Who is responsible
One of the most important features of California product liability is that you are not limited to suing the manufacturer. Strict liability can reach businesses all along the chain of distribution that put the product into the marketplace — including the manufacturer, distributors and wholesalers, and the retailer that sold it — even those who never touched the design or assembly. The California Supreme Court extended strict liability to retailers in Vandermark v. Ford Motor Co. (1964) 61 Cal.2d 256, reasoning that businesses engaged in selling products to the public are part of the overall enterprise that should bear the cost of injuries from defective goods. This matters in real cases: if the manufacturer is overseas, out of business, or hard to sue, an injured person may still have a path to recovery through a California seller. Which parties belong in a particular case is a fact- and law-intensive question — exactly the kind of thing to review with an attorney.
Your burden of proof
Strict liability lowers the bar compared to a negligence case, but it is not automatic. In a typical strict product liability claim, the injured person generally must show, at a minimum: that the defendant manufactured, distributed, or sold the product; that the product had a defect (manufacturing, design, or warning) when it left the defendant's control; that the product was used or misused in a reasonably foreseeable way; that the injured person was harmed; and that the defect was a substantial factor in causing that harm. Defenses still apply. For example, a company may argue the product was substantially modified after it left their hands, or that it was put to a use no one could reasonably foresee. Comparative fault can also reduce — but generally not eliminate — recovery. These elements and defenses are general points to confirm with a licensed California attorney.
Filing deadline
A product injury claim is still a personal injury claim, so the general California deadline (statute of limitations) for a personal injury caused by a defective product is two years from the date of injury under Code of Civil Procedure section 335.1. California's discovery rule can affect when that clock starts in some cases — for instance, when an injury or its cause was not immediately obvious. Deadlines for property damage and other claim types differ, and exceptions exist (such as claims involving minors). Do not guess — check your specific deadline with the California Statute of Limitations calculator, and confirm it with a licensed California attorney.
Common mistakes
Search results can make a complicated injury issue feel simple. These are the mistakes that most often create confusion later.
Assuming you must prove the company was careless — in a strict product liability claim, the focus is on whether the product was defective and caused your injury, not on negligence.
Only thinking about suing the manufacturer and overlooking the retailer, distributor, or wholesaler in the chain of distribution.
Throwing away or repairing the product, packaging, or instructions, when defective-product cases often turn on expert analysis of the actual item.
Guessing your deadline — the general two-year period under CCP section 335.1 can be changed by the discovery rule, property-damage rules, and other exceptions.
Treating any odd use as fatal to your claim — California's rule generally covers use, and even some misuse, that is reasonably foreseeable.

FAQ
Usually not in a strict product liability claim. The focus is on whether the product was defective and caused your injury — not on whether a specific person was negligent. This is general information; confirm how it applies to your situation with a licensed California attorney.
Often yes. California allows strict liability against sellers and others in the chain of distribution, not only the manufacturer. Which parties to name is a case-specific legal question to review with a licensed California attorney.
Manufacturing defects (this unit came out wrong), design defects (the design itself is unsafe), and warning or marketing defects (inadequate warnings or instructions). The exact tests are technical, so confirm how they apply with an attorney.
California's rule generally covers use — and even some misuse — that is reasonably foreseeable. A use no one could reasonably anticipate may be a defense. Whether your use qualifies is a fact-specific question for a licensed California attorney.
