If you feel you must bring a lawsuit under the lemon law for a refund or replacement vehicle, you should consult an attorney (you may be eligible to recover the attorney`s fees if you win). The law allows you to file suit any time within three years of the date of the original delivery of the vehicle, if you first reported the defect within the warranty period, or two years, whichever comes first. As of April 1995, if you go through a manufacturer`s arbitration program, you have six months to appeal in court. The company has only 30 days to appeal in court.
