Wyoming lemon laws are dealt with in Wyoming Statutes, Title 40, Chapter 17 (Motor Vehicles), Section 40-17-101. et seq.  A motor vehicle is defective if it does not conform to all applicable express warranties.  The prescribed time limit for manufacturer repair is the period of one (1) year following the date of original delivery of the motor vehicle to the consumer.  This time limit is prescribed in Section 40-17-101(b).  During this time limit the consumer should report any nonconformity, defect, or condition to the manufacturer, its agent, or its authorized dealer.  The manufacturer, its agent, or its authorized dealer should repair or correct the nonconformity, defect, or condition at no charge to the consumer, within this time period.

Certain remedies are available to the consumer if the manufacturer, its agent, or authorized dealer is unable to repair or correct any nonconformity, defect, or condition which results in significant impairment of the motor vehicle, after a reasonable number of attempts.  The manufacturer should either replace the motor vehicle with a new or comparable motor vehicle of the same type and similarly equipped, or accept return of the motor vehicle from the consumer and refund to the consumer.  The refund consists of full purchase price with reasonable collateral charges.  The consumer has the option to choose from either of the two remedies.  From the full purchase price, the manufacturer can deduct a reasonable allowance for the consumer’s use of the motor vehicle.  The remedies are enumerated under Section 40-17-101(c).
