Section 11.15 - Used Vehicle Dealer Warranty(1) Every dealer that sells a used vehicle that is covered by the warranty established by M.G.L. c. 90, § 7N1/4 shall complete and give to the consumer at the time of sale at no charge a copy of the warranty set forth in 201 CMR 11.22(3) on a separate piece of paper.(2) The dealer shall ask the consumer to sign and date a copy of that warranty and shall retain that copy for 12 months after the delivery of the vehicle to the consumer. This signed copy will serve as evidence that a copy of the warranty was provided to the consumer as required by M.G.L. c. 90, § 7N1/4.(3) If the dealer gives the consumer a copy of the warranty at the time of sale, the warranty period will commence to run on the date the consumer accepts delivery of the vehicle. If the dealer fails to give the consumer a copy of the warranty at the time of sale, or gives the consumer a copy that is incomplete or inaccurate, the warranty period will not begin until the dealer gives the consumer a complete, accurate copy. However, a dealer's failure to give the consumer a complete, accurate copy of the warranty will not affect the consumer's rights to warranty repairs and to arbitration.(4) No dealer shall seek a waiver by a consumer of his or her rights pursuant to M.G.L. c. 90, § 7N1/4 and 201 CMR 11.00. Any such waiver will be unenforceable.
