Under the Massachusetts Lemon Laws, you may be eligible for compensation for your used vehicle if it has at least one qualifying defect that impairs its use or safety. The car must have been purchased from a Massachusetts dealer and be used for personal or family purposes (i.e. not used primarily for business). In Massachusetts, a dealer is defined as someone who sells more than 3 cars in a 12-month period, even if they do not have a valid used car dealer license.

1. If the dealer or his agent fails to correct a malfunction or defect as required by the warranty specified in this section which substantially impairs the value of the used motor vehicle to the consumer after a reasonable period of time, the dealer shall accept return of the used motor vehicle from the consumer and refund to the consumer the full purchase price, or in the case of a lease contract all payments made under the contract, including sales or compensating use tax, less a reasonable allowance for any damage not attributable to normal wear or usage, and adjustment for any modifications which either increase or decrease the market value of the vehicle or of the lease contract, and in the case of a lease contract, shall cancel all further payments due from the consumer under the lease contract. In determining the purchase price to be refunded or in determining all payments made under a lease contract to be refunded, the purchase price, or all payments made under a lease contract, shall be deemed equal to the sum of the actual cash difference paid for the used motor vehicle, or for the lease contract, plus, if the dealer elects to not return any vehicles traded-in by the consumer, the wholesale value of any such traded-in vehicles as listed in the National Auto Dealers Association Used Car Guide, or such other guide as may be specified in regulations promulgated by the commissioner of motor vehicles, as adjusted for mileage, improvements, and any major physical or mechanical defects in the traded-in vehicle at the time of trade-in. The dealer selling or leasing the used motor vehicle shall deliver to the consumer a written notice including conspicuous language indicating that if the consumer should be entitled to a refund pursuant to this section, the value of any vehicle traded-in by the consumer, if the dealer elects to not return it to the consumer, for purposes of determining the amount of such refund will be determined by reference to the National Auto Dealers Association Used Car Guide wholesale value, or such other guide as may be approved by the commissioner of motor vehicles, as adjusted for mileage improvements, and any major physical or mechanical defects, rather than the value listed in the sales contract. Refunds shall be made to the consumer and lienholder, if any, as their interests may appear on the records of ownership kept by the department of motor vehicles. If the amount to be refunded to the lienholder will be insufficient to discharge the lien, the dealer shall notify the consumer in writing by registered or certified mail that the consumer has thirty days to pay the lienholder the amount which, together with the amount to be refunded by the dealer, will be sufficient to discharge the lien. The notice to the consumer shall contain conspicuous language warning the consumer that failure to pay such funds to the lienholder within thirty days will terminate the dealer's obligation to provide a refund. If the consumer fails to make such payment within thirty days, the dealer shall have no further responsibility to provide a refund under this section. Alternatively, the dealer may elect to offer to replace the used motor vehicle with a comparably priced vehicle, with such adjustment in price as the parties may agree to. The consumer shall not be obligated to accept a replacement vehicle, but may instead elect to receive the refund provided under this section. It shall be an affirmative defense to any claim under this section that:
