The Lemon Law in Idaho

New motor vehicle defects reported during the express warranty, the first two years after delivery, or the first 24,000 miles, whichever ends earliest, must be repaired. A reasonable number of repair attempts is presumed if, in that period, the same defect was repaired four or more times and still exists (the manufacturer must have had at least one chance to repair it), the vehicle was out of service for repairs 30 or more business days in total, or a defect causing complete failure of the braking or steering system that is likely to cause death or serious injury was repaired at least once. If a defect impairing use or market value cannot be fixed, the manufacturer must replace the vehicle or refund what the consumer paid (capped at 105% of the manufacturer's suggested retail price) plus taxes, fees and certain towing and rental costs, minus a mileage-based allowance for use. The consumer may reject a replacement and insist on a refund.

1) Written notice: the repair presumption applies only if the manufacturer, its agent or its authorized dealer has received prior written notice from or on behalf of the consumer at least once and had an opportunity to fix the defect. A dealer or agent that receives the notice must forward it to the manufacturer by certified mail. The dealer must give buyers a written statement that, to get a refund or replacement, they must first notify the manufacturer, agent or dealer in writing and allow a repair opportunity. 2) Final repair attempt: the manufacturer must have at least one opportunity to repair before the presumption applies, even if it was not notified directly. 3) Arbitration: every manufacturer must run or take part in an informal dispute settlement program located in Idaho that meets federal rules (16 C.F.R. Part 703). The consumer must use it before suing for refund or replacement unless the manufacturer allows otherwise. Any consumer fee may not exceed the conciliation court filing fee in the county where the arbitration is held. Decisions are nonbinding unless the parties agree otherwise; a manufacturer must seek a new trial in district court within 30 days after receiving the decision. 4) Deadline: a lawsuit must be started within 3 years after original delivery. If the consumer applied to the dispute program within those 3 years, an appeal of its decision must be filed within 3 months after the final decision.

The lemon law covers new vehicles. The Attorney General explains that federal law requires used car dealers to post a Buyers Guide saying whether the car comes with a warranty, "as is" (no warranty), or with implied warranties only; if a used car is sold "as is," there is no express or implied warranty. There is no three-day cooling-off period for new or used car purchases.
