A defect must affect the use, value or safety of the vehicle. The law applies while the vehicle is under the manufacturer's expressed warranty or up to one year after the date of delivery, whichever expires earlier. Vehicle Owner Responsibilities New-vehicle owners must report problems or defects in writing to the manufacturer to use the provisions of the Lemon Law. The law also stipulates that a replacement vehicle must be acceptable to the consumer. If after repairs are made to your vehicle you still believe the vehicle does not conform to the warranty, but the manufacturer or dealer has indicated that it doesn't believe you are due a refund, then submit a complaint according to the manufacturer's informal dispute settlement procedure.
Most automobile manufacturers have appeals procedures.
These arbitration boards try to resolve problems consumers have with the manufacturer or dealer. The address and phone number of your manufacturer's consumer appeals or arbitration center are listed in your owner's manual. During or at the end of the dispute procedure, the manufacturer may make a settlement offer. You must decide whether to accept the offer or try to get a refund under the Lemon Law by going to court. If you decide to go to court, the Lemon Law provides for a private cause of action.
