In the state of Massachusetts, the law protects consumers who have purchased defective vehicles. A “lemon” is defined as a new or leased automobile that has a serious defect that impairs a vehicle’s performance or safety or decreases its market value. It is the responsibility of the car dealer or auto owner to disclose all information about any defects the car may have, and to place the repair and maintenance of those defects under warranty. Additionally, consumers have the right under Massachusetts law to void any transaction wherein the consumer was sold a flawed vehicle. Under law, the dealer or car owner must refund the consumer’s money if it is proven that the car has defects that were not disclosed and agreed upon at the time of purchase.
