The Massachusetts lemon law is designed to protect customers who have serious defects in their new cars. The state defines a lemon as a vehicle that impairs the use, market value or safety of the vehicle and which has not yet been fixed after a reasonable number of attempts.

This law applies to new cars, motorcycles, cans and trucks bought in Massachusetts from a car dealer for personal or family use. This is valid for one year or 15,000 miles from the original date of delivery whichever comes first. The law does not cover auto homes as well as vehicles used for off-road or business.
