The Massachusetts Lemon Law protects consumers who have serious defects in their new cars. The law defines a lemon as a new or leased motor vehicle that has a defect which substantially impairs the use, market value, or safety of the vehicle, and which has not been repaired after a reasonable number of attempts. (M.G.L. c. 90, §7N1/2)
If your new or leased vehicle has a substantial defect that still exists or recurs after a reasonable number of repair attempts, then you may have the right to a refund or replacement vehicle. Keep in mind that not all car problems are serious enough to qualify under the Lemon Law.
