The product liability statute of limitations is the deadline for filing a lawsuit over a defective product, and it typically runs one to six years from the date of injury or, in some cases, from the date you discovered the injury. Most states land in the two-to-four-year range for personal injury claims. A second and less familiar deadline, the statute of repose, exists in about 19 states and can bar your claim based on how long ago the product was sold, even if you were injured yesterday. Miss either clock and the case is almost always over.
How the Filing Clock Works
The statute of limitations is the primary deadline. It starts running when you’re injured by a defective product or, in some situations, when you first realize the product caused your harm. Every state sets its own timeframe. Some give injured consumers as little as one year; others allow up to six. Most fall in the two-to-four-year range for personal injury.
The trigger date matters as much as the length. In the majority of states, the clock starts on the date of the accident or injury. If a power tool breaks apart and cuts your hand on March 15, that’s usually day one. File even one day past the deadline and a court will almost certainly dismiss the case. Defense attorneys watch these dates closely and routinely move to throw out late-filed suits.
The legal theory behind your claim can also affect which deadline applies. Product liability cases generally fall into three categories: manufacturing defects (the product was built wrong), design defects (the product was designed in a way that made it unreasonably dangerous), and failure-to-warn claims (the manufacturer didn’t adequately disclose known risks). In most states, the same statute of limitations covers all three. In a few jurisdictions, different theories can trigger different filing windows, so identifying the correct legal theory early matters.
The Discovery Rule for Hidden Injuries
Some injuries don’t show up right away. A person exposed to a toxic chemical in a consumer product might not develop symptoms for years. A medical implant might slowly degrade inside the body before anyone realizes something is wrong. A strict injury-date rule would bar these claims before the person had any reason to know they were hurt.
The discovery rule addresses this problem. Under this exception, the statute of limitations doesn’t begin until the injured person discovers, or reasonably should have discovered, both the injury and the product that caused it. Courts look at medical records, expert opinions, and the circumstances of the exposure to pinpoint when a reasonable person would have connected the dots. This is where most latent-injury cases are won or lost, because the defendant will argue you should have figured it out sooner.
The rule doesn’t buy unlimited time. Once you know or should know about the injury and its likely cause, the standard filing period kicks in. If your state allows two years and you discover the connection in June, you generally have two years from that point. Waiting to see how bad the symptoms get, or hoping to identify a stronger legal theory, won’t extend the deadline.
Warranty Claims Run on a Different Clock
A product liability claim can be brought under a breach-of-warranty theory, not just negligence or strict liability. That matters for timing, because warranty claims often follow a separate set of rules.
Under the Uniform Commercial Code, which nearly every state has adopted in some form, the statute of limitations for breach of a sales contract is four years. The critical difference is when the clock starts: for warranty claims, it generally begins at the point of sale or delivery, not when the injury occurs. A warranty claim can therefore expire before you’re ever hurt. If the product injures you shortly after purchase and your state’s personal injury deadline is shorter than four years, the warranty route might give you more time.
States split on whether the four-year warranty deadline applies when the damages are personal injuries rather than economic losses. A majority apply the warranty timeline to all breach-of-warranty claims regardless of the type of harm. A minority look at the damages being sought and route personal injury claims through the standard tort deadline instead. Which approach your state follows can decide whether the case is timely.
When the Clock Pauses
Certain circumstances stop the filing clock even though the deadline would otherwise be ticking. This is called tolling, and it recognizes that some plaintiffs face genuine barriers to filing on time.
Minors and Incapacitated Individuals
When the injured person is a child, most states pause the statute of limitations until the child turns 18. A five-year-old injured by a defective toy doesn’t lose the right to sue simply because no adult filed during childhood. The full filing period typically begins on the child’s 18th birthday. Similar protections apply to individuals who are mentally incapacitated at the time of the injury. The clock generally stays paused until the person regains legal capacity.
Fraudulent Concealment
If a manufacturer actively hides a known defect, the law doesn’t reward that dishonesty by letting the filing deadline expire while consumers remain in the dark. When a company uses deceptive practices to prevent people from discovering a product’s danger, courts will pause the clock until the concealment is uncovered or reasonably should have been uncovered. The plaintiff typically needs to show the manufacturer took affirmative steps to hide the defect, not merely that it failed to volunteer information.
Active Military Service
Federal law provides a separate tolling protection for servicemembers. Under the Servicemembers Civil Relief Act, any period of active military service is excluded from the calculation of filing deadlines for civil actions. If you’re injured by a defective product and then deployed, the time on active duty doesn’t count against your statute of limitations. This protection applies broadly to actions in any court or government agency, though it does not extend to internal revenue matters.1Office of the Law Revision Counsel. 50 U.S. Code 3936 – Statute of Limitations
Statutes of Repose: The Absolute Cutoff
A statute of repose is a fundamentally different deadline. It starts when the product is first sold, delivered, or placed into the stream of commerce, and it runs regardless of whether anyone has been hurt yet. Once it expires, the right to sue is gone even if you’re injured the next day.
About 19 states impose a statute of repose on product liability claims. The periods vary considerably, from as short as five years in some states to as long as 20 in others, with most in the 10-to-15-year range. A handful of states tie the deadline to the product’s “useful safe life” rather than a fixed number of years. Under this approach, drawn from the Model Uniform Product Liability Act’s presumption that a product’s useful safe life does not exceed ten years, the cutoff is based on how long a product of that type would reasonably be expected to remain safe. That presumption can be challenged with evidence that a particular product was designed to last longer.
The practical impact is harsh. A furnace installed in 2010 that develops a crack and causes a fire in 2024 may already be beyond suit in a state with a 12-year repose period running from purchase, even though the homeowner had no way to detect the defect. The discovery rule, tolling for minors, and other equitable exceptions generally do not override a statute of repose. It functions as an outer boundary the legal system treats as final.
Exceptions for Latent Disease and Toxic Exposure
The collision between statutes of repose and latent-injury claims has forced some states to carve out exceptions where the harm physically cannot manifest within the repose window. These exceptions are narrower and less common than many plaintiffs expect.
Some states exclude specific substances known to cause delayed illness. Asbestos is the most common carve-out, but a few states have added exceptions for silicone gel breast implants, dioxins, and polychlorinated biphenyls (PCBs). Some jurisdictions also exempt injuries caused by groundwater contaminated with hazardous substances. A broader category of exceptions exists in states that suspend repose when the “injury-causing aspect” of the product was not discoverable by a reasonably careful person before the repose period expired, or when the harm resulted from prolonged exposure.
Courts often read these exceptions very narrowly. A state that exempts “asbestos” claims may not extend that protection to products that contain asbestos as a component. Relying on a latent-disease exception without verifying how your state’s courts have applied it is a serious gamble.
Federal Repose for General Aviation Aircraft
The General Aviation Revitalization Act imposes an 18-year federal cutoff on product liability claims against manufacturers of general aviation aircraft. The clock starts on the date the aircraft was first delivered to a purchaser or lessee, or, for replacement parts, the date the part was installed. After 18 years, manufacturers are shielded from suits for death, personal injury, or property damage arising from an accident involving the aircraft.2Office of the Law Revision Counsel. 49 USC 40101 – Policy
Four exceptions apply. The repose period does not bar a claim if the manufacturer knowingly misrepresented or concealed required information from the Federal Aviation Administration and that information is causally related to the injury. It also does not apply when the injured person was a passenger receiving emergency medical treatment, when the injured person was not aboard the aircraft at the time of the accident, or when the claim is brought under a written warranty that would be enforceable but for the statute.2Office of the Law Revision Counsel. 49 USC 40101 – Policy This federal statute overrides any longer state-law repose period for covered aircraft.
When Your Claim Crosses State Lines
Product liability cases often involve more than one state. You might buy a product in one state, get injured in another, and file suit in a third. Each of those states may have a different statute of limitations, and which one applies can decide whether the claim survives.
Many states have borrowing statutes, designed to prevent forum shopping. A borrowing statute generally tells the court to look at where the claim arose, usually where the injury happened, and apply that state’s filing deadline if it has already expired. The idea is to stop a plaintiff from filing in whichever state has the longest deadline. If your claim is time-barred where you were injured, a borrowing statute will typically bar it in the forum state as well, even if the forum state’s own deadline hasn’t run.
Determining where a claim “arose” isn’t always straightforward. Most courts point to where the injury occurred, but some look at where the defective product was sold or where the defendant is located. If you were injured in a state with a short filing window but purchased the product in a state with a longer one, which law controls can make or break the case. Getting legal advice early matters, because assumptions about which state’s deadline applies can forfeit a claim.
Claims Involving a Death
When a defective product kills someone, two distinct claims can arise, each with its own filing timeline. Wrongful death claims compensate surviving family members for their losses, such as the income the deceased would have earned, the companionship they provided, and funeral costs. Survival actions continue whatever claim the deceased person could have brought while alive, covering pain, suffering, and medical expenses between injury and death.
Wrongful death statutes of limitations range from one year to four years. The majority of states set the deadline at two years from the date of death. A smaller group allows three years, and a few allow only one. The clock almost always starts on the date of death, not the date of the initial injury, which matters when a person survives for months or years after being harmed.
Survival action deadlines work differently. Because a survival action steps into the shoes of the deceased, the applicable statute of limitations is often the same one that would have applied to the deceased person’s original claim. If that filing window was already running before death, the surviving party typically gets a limited additional period, often one year, to continue or file the action. Whether the discovery rule applies to wrongful death claims remains unsettled in many jurisdictions, with courts split on whether the clock can start before the date of death in latent-injury cases.
In states that also impose a statute of repose, wrongful death cases face the same hard cutoff. A family whose loved one dies from a defective product 15 years after it was sold may find the claim barred by repose even though the wrongful death deadline, measured from the date of death, has barely begun to run.
