Section 51-07-18 - Duty to replace defective passenger motor vehicle or refund price - Prerequisite of using available informal dispute settlement process1. If the manufacturer, its agent, or its authorized dealer is unable to make the passenger motor vehicle conform to any applicable express warranty by repairing or correcting any defect or condition that substantially impairs the use and market value of the passenger motor vehicle, after a reasonable number of attempts, the manufacturer shall replace that passenger motor vehicle with a comparable passenger motor vehicle or accept return of the passenger motor vehicle from the consumer, and refund to the consumer the full purchase price, including all collateral charges, less a reasonable allowance for the consumer's use of the vehicle not exceeding ten cents per mile [1.61 kilometers] driven or ten percent of the purchase price, whichever is less. Refunds must be made to the consumer, the lessor, and the lienholder, if any, as their interests may appear. A reasonable allowance for use is the amount directly attributable to use by the consumer before the consumer's first report of the nonconformity to the manufacturer, agent, or dealer, and during any subsequent period when the vehicle is not out of service for repair.2. It is an affirmative defense to any claim under sections 51-07-16 through 51-07-22: a. That an alleged nonconformity does not substantially impair the use and market value of the passenger motor vehicle; orb. That a nonconformity is the result of abuse, neglect, or unauthorized modifications or alterations of the passenger motor vehicle by a consumer.3. If a manufacturer has established or participates in an informal dispute settlement procedure that substantially complies with the substantive rules of the federal trade commission, 16 CFR 703, or if the manufacturer participates in a consumer and industry appeals, arbitration, or mediation appeals board whose decisions are binding on the manufacturer, the remedy under subsection 1 is not available to a consumer who has not first resorted to that procedure. If the consumer requests an oral presentation before the board or dispute settlement mechanism, the hearing must take place in the state in which the consumer resides. The attorney general shall, on application, issue a determination of whether an informal dispute resolution mechanism qualifies under this subsection.
