All states have some form of statute of limitations, which limits the time allowed for filing a lawsuit. The time frame in which the statute of limitations runs usually begins from the time of the injury as a result of the defect. However, most states have some form of a delayed discovery rule, which states that the statute does not begin to run until the injury is discovered. This may be important when the injury is not obvious, perhaps until years later. There is a related statute in some jurisdictions called a statute of repose. It essentially provides that no claim can be made based upon a defective product beyond a specified number of years after the date of manufacture.
