Connecticut Lemon Law: Arbitration, Tests & Free Check

The short answer

Connecticut’s Lemon Law (C.G.S. §§ 42-179 to 42-190) covers defects within 2 years or 24,000 miles. It presumes enough attempts after 4 repairs, 2 repairs of a serious safety defect or 30 days out of service. The Department of Consumer Protection runs a state arbitration program: the fee is $50, decisions usually come within 60 days and bind both sides. Refunds deduct price × miles before the return ÷ 120,000.

Connecticut set up the country’s first state lemon law arbitration program in 1982, and it still runs it through the Department of Consumer Protection. This guide explains who is eligible, the repair tests, the $50 application, what happens at the hearing, and how the refund and title brand work, using Chapter 743b of the General Statutes and the Department’s program guide.
