Another way of referring to this law is the Motor Vehicle Warranty Enforcement Act. If a car can’t be repaired, or needs repeated repairs, it can cause a horrendous hardship on the consumer. Thanks to the lemon law, cars fitting this profile must be replaced or repurchased by the manufacturer.
Some form of the lemon law exists in all 50 states. A used car lemon law, however, only exists (currently) in six states. Those states include Rhode Island, New York, New Jersey, Minnesota, Massachusetts, and Hawaii.
