For a vehicle to be considered a lemon, it must meet certain requirements. While each state is different, there are some general things that hold true across the board. First of all, the vehicle needs to have some type of defect or non-conformity. Under most state laws, the defect must have taken place within a specific period of time or a certain number of miles after the vehicle was purchased or leased. Additionally, most state lemon laws require that the defect or non-conformity could not be fixed after several repair attempts. While state lemon laws for cars usually only apply to new, the Magnuson-Moss Warranty Act, also known as the federal Lemon Law, applies to all cars covered by a warranty, whether the car is new or used. It is important that you speak to an experienced lemon law attorney who may assess your rights.
