You will generally be given four years to file a lemon law claim starting from the date you experienced the issue with your vehicle, not when you purchased it. This timeframe is relevant to new and used cars, as long as the used car was sold with a warranty.
Be sure to act promptly as delaying this process can impact your opportunity to acquire a successful outcome. Such cases can also be complex, so speaking to a qualified lemon law attorney is advisable to help you understand your legal rights and options.
