Synopsis As Introduced Creates the New Vehicle Buyer Protection Act of 2017. Provides that if a manufacturer is unable to service or repair a new motor vehicle to conform to the applicable express warranties after a reasonable number of attempts, the manufacturer shall either promptly replace the new motor vehicle or make restitution to the buyer. Provides that it shall be presumed that a reasonable number of attempts have been made to conform a new motor vehicle to the applicable express warranties if, within 18 months from delivery to the buyer or 18,000 miles on the odometer of the vehicle: (1) the same nonconformity results in a condition that is likely to cause death or serious bodily injury if the vehicle is driven after 2 or more repairs; (2) the same nonconformity has been subject to repair 4 or more times; or (3) the vehicle is out of service by reason of repair for more than 30 calendar days since delivery of the vehicle to the buyer. Requires a buyer to initiate a qualified third-party dispute resolution process, if available, before asserting the presumption that a reasonable number of attempts have been made to repair the nonconformity. Prohibits a person from selling a motor vehicle without first disclosing to the prospective buyer that the vehicle had a nonconformity and the nonconformity was corrected.
