Montana Lemon Law
If after (1) the same nonconformity has been subject to repair for or more times by the manufacturer of its agent or authorized dealer during the warranty period but the nonconformity continues to exist; or (2) the vehicle is out of service because of nonconformity for a cumulative total of 30 or more business days during the warranty period after notification of the manufacturer, agent or dealer, the manufacture or its agent or authorized dealer is unable, during the warranty period, to conform the new motor vehicle to any applicable express warranty by repairing or correcting any defect or condition that substantially impairs the use and market value or safety of the motor vehicle to the consumer, the manufacturer shall replace it with a new motor vehicle of the same model and style and of equal values, unless for reasons of lack of availability such replacement is impossible, in which case the manufacturer shall replace it with a vehicle of comparable market value. As an alternative to replacement, the manufacturer may accept return of the new motor vehicle from the consumer upon refund to him of the full purchase price, plus reasonable collateral charges and incidental damages, less a reasonable allowance for the consumer’s use of the motor vehicle. The refund shall be paid to the consumer and to a lienholder, if any, in proportion to their interests. The consumer must first notify the manufacturer or it’s agent.
