Product Liability in California: Your Legal Rights After a Defective Product Injury
- Last Updated:
Product liability in California allows people injured by defective products to seek compensation from manufacturers, distributors, and retailers. Under the state’s strict liability doctrine, you generally do not have to prove the company was negligent.
You only need to show that the product had a defect (in design, manufacturing, or warnings), it caused your injury, and you were using it in a reasonably foreseeable way. Most personal injury claims must be filed within two years under California Code of Civil Procedure § 335.1.
A lithium-ion battery in a household device can ignite without warning. A car’s airbag can rupture instead of inflating safely. A common medication can carry serious risks the label never mentions.
According to the U.S. Consumer Product Safety Commission, deaths, injuries, and property damage from consumer product incidents cost the nation hundreds of billions of dollars every year. When everyday items cause harm, California product liability law gives consumers one of the strongest legal frameworks in the country to hold companies accountable.
This article walks through how product liability works in California, what you actually have to prove, who can be on the hook, what damages you may recover, and the deadlines you cannot afford to miss.
What Is Product Liability Under California Law?
California pioneered modern strict products liability. In Greenman v. Yuba Power Products, Inc., 59 Cal. 2d 57 (1963), the California Supreme Court held that a manufacturer is strictly liable when a product placed on the market causes injury to a person using it as intended. That ruling, later reflected in standard jury instructions like CACI No. 1200, shifted the legal landscape so that injured users no longer had to untangle complex corporate decision-making to recover compensation.
How does strict liability differ from negligence?
In a typical negligence case, you have to prove the defendant failed to use reasonable care. Strict liability removes that hurdle. The question is not whether the company tried hard enough; it is whether the product itself was defective and caused your injury. That said, strict liability is not absolute liability. The manufacturer is not the insurer of every accident. You still have to show that the product had a defect, the defect existed when it left the company’s control, and you used the product in a reasonably foreseeable way.
Who can be held responsible in the chain of distribution?
Liability is not limited to the company that built the item. Anyone who is part of the overall producing and marketing enterprise can be a defendant. That generally includes:
- Manufacturers of the finished product
- Manufacturers of component parts
- Wholesalers and distributors
- Retailers, including big-box and small stores
- Importers who bring foreign-made products into the U.S.
Casting a wide net matters because some defendants disappear, go bankrupt, or sit overseas beyond the reach of a U.S. court. Spreading the claim across the chain helps make sure an injured person actually has someone collectable to recover from.
What about products sold through online marketplaces?
This is one of the most important developments in California product liability law in years. In Bolger v. Amazon.com, LLC, 53 Cal.App.5th 431 (2020), the California Court of Appeals held that Amazon could be strictly liable for a defective laptop battery sold by a third-party seller on its platform. Amazon stored the product in its warehouse, charged the customer, shipped it in Amazon-branded packaging, and controlled the customer relationship. That, the court reasoned, was enough to bring Amazon inside the chain of distribution. Online buyers in California now have a real path to hold marketplaces accountable when overseas sellers vanish.
What Types of Product Defects Can Lead to a Claim?
Manufacturing defects: When something goes wrong on the assembly line
A manufacturing defect happens when a product comes off the line differently from how it was intended to be made. The design might be perfectly safe, but a particular batch, unit, or component was put together incorrectly. Think of a single car with improperly torqued lug nuts, or a contaminated bottle of medication in an otherwise clean production run. The plaintiff has to show that the specific product that caused the injury did not match the manufacturer’s own specifications.
Design defects: When the product is dangerous as intended
Design defect cases challenge the blueprint itself. Every unit produced has the same problem because the underlying design is unsafe. California uses two tests, set out in Barker v. Lull Engineering Co., 20 Cal. 3d 413 (1978):
- Consumer expectations test: the product failed to perform as safely as an ordinary consumer would expect when used in a reasonably foreseeable way.
- Risk-benefit test: the risks of the design outweigh the benefits, considering factors like the gravity of potential harm, the feasibility of a safer design, and the cost.
Examples include vehicles prone to rollover, children’s products with small detachable parts, and medical implants that fail at predictable rates.
Failure to warn: When the label leaves you in the dark
A product can be designed and manufactured correctly and still be defective if the company failed to warn users about a non-obvious risk or did not provide adequate instructions. Under CACI No. 1205, a seller can be strictly liable for failure to warn when the risk was known or knowable based on accepted scientific knowledge at the time of distribution. Common examples include prescription drugs with undisclosed side effects, cleaning chemicals without proper hazard warnings, and industrial equipment shipped without safe-use instructions.
How Long Do You Have to File a Product Liability Lawsuit in California?
Most California product liability claims for personal injury must be filed within two years of the injury under Code of Civil Procedure § 335.1. Property damage claims generally have a three-year deadline. Missing the deadline almost always ends a case before it begins, regardless of how serious the injury is, so this is usually the first issue we examine.
Why the discovery rule sometimes extends the deadline
Not every injury shows up right away. A defective hip implant might cause symptoms years after surgery. A medication might be linked to a serious illness only after long-term use. California’s discovery rule generally pauses the clock until the injured person knew, or reasonably should have known, both that they were hurt and that the harm was caused by something the manufacturer did. This is fact-specific and frequently disputed by defense counsel, so do not wait if you suspect a connection.
How property damage claims differ from injury claims
If a defective product damages your property without injuring anyone (for example, a faulty appliance that starts a fire and burns belongings), the deadline is typically three years from the date of the property damage. When the same incident causes both injury and property damage, two different clocks may run on the same case.
What Damages Can You Recover in a Product Liability Case?
California allows broad recovery for losses caused by a defective product. The exact mix depends on the severity of the injury and the strength of the evidence.

Economic damages put a dollar figure on out-of-pocket harm:
- Past and future medical expenses, including surgery, rehabilitation, prescriptions, and assistive devices
- Lost wages and lost earning capacity
- Property damage, replacement, or repair
- Costs of in-home care or modifications
Non-economic damages compensate for harm that money cannot easily measure:
- Physical pain and suffering
- Emotional distress and anxiety
- Disfigurement and scarring
- Loss of enjoyment of life
Punitive damages may be available where a defendant acted with malice, oppression, or fraud, such as concealing a known defect to protect profits. These are not awarded in every case, but they can be significant when the evidence shows reckless corporate behavior.
A note on shared fault: California follows pure comparative fault. If a jury finds you partly responsible, your award is reduced by your percentage of fault but not eliminated. Defendants almost always argue that the user did something wrong, so preserving evidence early is critical.
What Should You Do After Being Injured by a Defective Product?
The hours and days after an injury matter. Here is a practical checklist we share with people who call after an incident:
- Get medical care first. Your health is the priority, and contemporaneous medical records anchor the case.
- Preserve the product. Do not throw it out, repair it, return it for a refund, or send it back to the manufacturer. The product itself is often the single most important piece of evidence.
- Save the packaging, instructions, and receipt. These documents contain the chain of distribution and how the product was marketed to you.
- Take photos. Capture the product, the scene, and your injuries from multiple angles, with timestamps if possible.
- Identify witnesses. Get names and contact information for anyone who saw what happened.
- Report serious incidents. You can submit a report to the U.S. Consumer Product Safety Commission at SaferProducts.gov or, for vehicle issues, to the National Highway Traffic Safety Administration.
- Avoid posting on social media. Defense lawyers regularly use posts to argue that an injury is exaggerated.
- Be careful with insurance adjusters. You are not required to give a recorded statement, and early statements can be used against you.
- Track everything. Keep a folder or simple spreadsheet of medical visits, missed work, and out-of-pocket costs.
- Talk to a California product liability lawyer before signing anything. Quick settlement offers often appear early and can permanently waive your claim.
If a product was recalled after your injury, that is helpful but not required. Recalls strengthen many cases, but the absence of a recall does not mean a product was safe.
How Product Liability Cases Typically Move Forward
Most California product liability cases follow a similar arc:
- Investigation and preservation of the product
- Expert review (engineers, biomechanics specialists, toxicologists, or medical experts)
- Filing the complaint and serving the defendants
- Discovery, including depositions, internal documents, and design history
- Motion practice and challenges to expert testimony
- Mediation or settlement negotiations
- Trial, if the case does not resolve
Cases involving a single product and a single injured person can resolve in a year or two. Mass torts, multidistrict litigation, and class actions involving widespread injuries (defective drugs, hernia mesh, certain implants, vehicle airbag defects, and similar matters) may take longer but allow injured people to share investigative resources.
If you were injured at work by a defective tool or piece of machinery, your case can run on two parallel tracks: a workers’ compensation claim against your employer and a third-party product liability claim against the equipment maker. We discuss this overlap on our work injury lawyer page.
Frequently Asked Questions
1. Who can file a product liability claim in California?
Generally, any person injured by a defective product can file a claim, including the buyer, a family member, a borrower, or even a bystander. The injured person does not need to be the original purchaser. Eligibility can depend on factors like the type of defect, the type of product, and how the injury occurred.
2. Do I have to prove the manufacturer was negligent?
Often, no. Under California’s strict liability doctrine, the focus is on whether the product was defective and caused the injury, not whether the manufacturer acted carelessly. Negligence and breach of warranty may also be available as additional or alternative theories, depending on the facts.
3. What is the deadline to file a product liability lawsuit in California?
Personal injury claims generally must be filed within two years under California Code of Civil Procedure § 335.1. Property damage claims usually have a three-year limit. The discovery rule may extend these deadlines for injuries that were not immediately apparent, but exceptions can vary by situation.
4. Can I sue if the defective product was a gift or secondhand?
Generally, yes. California strict liability protects users and bystanders, not just original purchasers. However, claims involving used products may face additional defenses, especially if the product was modified after leaving the manufacturer or if a particular seller is exempt under California case law.
5. What if the company that made the product is overseas?
Suing foreign manufacturers can be difficult, but California law often allows claims against domestic distributors, retailers, and online marketplaces in the chain of distribution. The 2020 Bolger v. Amazon decision confirmed that online platforms may be held strictly liable for defective products sold through their websites under certain conditions.
6. Does a product recall help my case?
A recall can be useful evidence, but it is not required to bring a claim. Many valid product liability cases involve products that were never recalled. Likewise, a recall does not automatically prove liability. Each case still depends on showing a defect and a causal link to the injury.
7. How much does it cost to talk to a product liability lawyer?
Many California product liability attorneys, including our firm, offer free initial consultations and handle cases on a contingency fee basis. That generally means there is no upfront cost, and attorneys’ fees are paid only if the case results in a recovery. Specific fee terms can vary, so ask any lawyer to explain them clearly.
8. Do I have a case if I was partly at fault for the accident?
Possibly. California follows pure comparative fault. Your damages may be reduced by your percentage of responsibility, but you are not automatically barred from recovery. Defendants often raise misuse or modification as a defense, so preserving the product and any documentation is important.
