📋 Overview
State lemon laws were originally written to protect new car buyers. Most states (44 of 50) still apply only to new cars. Six states - Connecticut, Hawaii, Massachusetts, Minnesota, New Jersey, and New York - extend lemon law coverage to used cars. Plus the federal Magnuson-Moss Warranty Act (15 U.S.C. § 2301) covers any used car sold with an active manufacturer warranty.
