Hurt by a
defective product.
Product liability claims turn on the product itself: how it was designed and made, and what its warnings said. The product is also the central piece of evidence, and what happens to it in the days after an injury can decide whether a claim survives.
This page is general information, not legal advice for your situation. It does not create an attorney-client relationship. Every state's rules are different, and timelines can be short, so anyone with specific questions should consult a lawyer licensed in their state.
What makes a product liability claim different from other injury claims?
The focus moves toward the product. Most states apply strict liability to defective products, so a claim can succeed without proof that the manufacturer was careless, though design and warning claims in many states still depend on whether the manufacturer's choices were reasonable. What has to be shown is that the product was defective when it left the manufacturer's control and that the defect caused the injury. Negligence and breach of warranty claims can run alongside strict liability, each with its own rules.
Evidence is the second difference. The product is the main exhibit, and engineers for both sides routinely examine it early in the case.
Product claims can also sit beside a compensation claim. A worker hurt by a defective machine on the job may have one against the employer and another against the machine's maker, and the compensation side is explained on the workplace injuries page.
What kinds of defects support a product liability claim?
Manufacturing defects are the first category. The product came off the line different from its own design, as with a contaminated batch of food or a cracked weld in a ladder rail, and that departure caused the injury. Most states impose liability for a manufacturing defect even when the manufacturer's quality control was careful.
Design defects, the second category, affect every unit of a product. Courts in many states ask whether a safer design was available that would have reduced the risk at a reasonable cost while keeping the product useful. Other states ask whether the product was more dangerous than an ordinary consumer would expect, and some apply both tests.
Warning defects make up the third category. A product can be well made and well designed and still be defective if it lacked adequate instructions or warnings about risks that were not obvious. Disputes over warnings commonly turn on what the manufacturer knew about the risk, and when, along with whether a clearer warning would have changed what happened.
Who can be responsible for a defective product?
The manufacturer is typically the primary defendant, and the maker of a defective component may be responsible alongside the company that assembled the finished product. Strict liability can also reach the distributors and retailers further along the chain of sale.
Many states limit, by statute, claims against a seller that only passed the product along. Under those statutes, a seller that did not alter the product and had no reason to know of the defect generally escapes strict liability unless the manufacturer cannot be sued or cannot pay. Some states also require the manufacturer to cover an innocent seller's losses.
Courts in most states recognize crashworthiness claims, in which the injured person contends that a defect such as an airbag that failed to deploy made the injuries worse than the crash alone would have. Such a claim runs against the maker of the vehicle or of the failed part. It is separate from the insurance claims that follow a collision, which are covered on the car accident page.
What defenses come up in product liability cases?
Manufacturers often argue misuse or alteration. Misuse that no reasonable manufacturer could anticipate can defeat a claim, and so can a significant alteration after the sale that caused the injury.
Manufacturers also point to compliance with federal safety standards, which courts in most states treat as evidence that does not by itself settle whether the product was defective. A number of states give it the weight of a presumption.
In most states, comparative fault reduces a product liability recovery by the injured person's share of responsibility, and a share above about half bars recovery altogether.
Federal law supplies a separate defense for some products. Claims about medical devices approved through the Food and Drug Administration's premarket approval process are largely preempted, though devices cleared through its more common premarket notification route tend to remain open to claims. Many warning and design claims against generic drug makers are preempted too, while warning claims against brand-name makers can proceed under state law. Claims that a pesticide label needed a warning beyond what the Environmental Protection Agency approved are also preempted, at least where the agency evaluated that risk.
What happens in the first weeks after a product injury?
Medical care comes first, and the record from the first visit documents when and how the injury happened while the details are fresh.
Manufacturers and retailers may reach out within days of an injury report. Those calls commonly include a request to return the product for inspection, sometimes with an offer of a refund or replacement. A product sent back is no longer in the injured person's control.
The duty to preserve evidence runs in both directions. Once a claim is reasonably anticipated, the injured person generally has to keep the product in the condition the injury left it. A product thrown out or repaired can weaken the claim or end it.
What evidence matters most in a product liability claim?
The product matters most, including any broken pieces. Packaging and the instruction manual come next, because the warnings printed on them are part of the case. Purchase records show where and when the product was bought, and a serial or lot number may identify the production run.
Many consumer reports filed with the Consumer Product Safety Commission are published in a public database, and vehicle complaints filed with the National Highway Traffic Safety Administration are searchable too. Earlier reports of the same failure can reveal what a manufacturer knew beforehand.
Medical records can tie the injury to the product, and an unexplained gap in care gives the defense room to argue another cause.
What does personal injury counsel do in a product liability case?
Counsel sends preservation letters early. The manufacturer's letter covers design files and testing records, along with earlier complaints about the same product, while the seller's covers sales and return records. Both guard against records lost to routine deletion schedules.
Counsel then secures the product and arranges an inspection by a qualified engineer. From there, counsel identifies every company in the chain of sale and the insurance behind each one, then builds the claim from the engineering findings and the medical file. How injury claims are evaluated more broadly is set out in the injury overview.
How long do I have to bring a product liability claim?
Product cases can carry more than one deadline. The statute of limitations for an injury claim is generally measured in years, and for harm that develops slowly, many states start that period when the injury and its likely cause were discovered or should have been. A number of states also have a statute of repose, which runs from a fixed date such as the product's first sale or delivery and can bar a claim even before an injury occurs. Breach of warranty claims may run on a separate clock, which in many states starts at delivery. Counsel identifies early which deadlines may apply, and confirming a repose date can require sale records that take time to obtain.
Common questions
A recall can support a claim without proving it on its own. Recall filings with a federal regulator may show what the hazard was and when the company learned of it. Courts differ on how recall evidence is used at trial. A product can also be defective without ever being recalled. Accepting a recall repair or refund tends to leave an injury claim open, though paperwork with a release can end it, so counsel commonly reviews anything before it is signed. Some recall refunds require returning or destroying the product, and the evidence goes with it.
Responsibility starts with the manufacturer, wherever the product was bought. The third-party seller is part of the chain of sale and may be responsible on that basis. Overseas manufacturers and sellers can be difficult to serve with a lawsuit and to collect from, which is why the marketplace's role matters. Courts have divided on whether an online platform counts as a seller for strict liability purposes, with the answer turning partly on whether the platform stored and shipped the product itself. The order history and the seller's listing are worth saving early, because listings can disappear.
Sending the product back hands the central evidence to the company that would defend the claim. Once the product leaves the injured person's hands, the manufacturer controls how its condition is recorded and what testing is done on it. The injured person also carries a duty to preserve evidence once a claim is reasonably anticipated, so a lost or altered product can weaken the claim. Counsel typically answers these requests by proposing a joint inspection under an agreed protocol.
A departure from the instructions leaves many product claims intact. In most states, manufacturers are expected to anticipate foreseeable misuse, meaning the ways people predictably use a product, including some uses a label warns against. A claim can fail where the misuse was unforeseeable or where an alteration after the sale caused the injury. The injured person's own share of fault can reduce the recovery, and in most states a share above about half bars it.
Drug and device claims follow product liability rules, with added layers. In most states, a prescription drug maker meets its duty to warn by warning the prescribing doctor, so the question becomes what the doctor was told. Federal preemption limits claims about devices approved through the FDA's premarket approval process, a route few devices take, and about generic drug warnings. Where many people bring claims over the same drug or device, federal cases are frequently consolidated before one judge for pretrial proceedings, while each lawsuit remains separate, with its own damages. A doctor's prescribing or surgical error is a malpractice question.
