D.C. Lemon Law: Tests, Claims Board & Free Car Check

The short answer

The District of Columbia’s Lemon Law (D.C. Code §§ 50-501 to 50-509) covers the first 18,000 miles or 2 years. It presumes enough attempts after 4 repairs, 1 repair of a safety-related defect, or 30 days out of service. You must first file with the Board of Consumer Claims Arbitration, which decides within 60 days. You choose a refund or replacement; the deduction is capped at 10 cents a mile beyond 12,000. Sue within 4 years.

The District’s Lemon Law sends every claim to a local arbitration board first, gives a one-repair test for safety defects, and caps the refund deduction so that the first 12,000 miles cost you nothing. It also protects used-car buyers by requiring dealers to disclose known defects. This guide explains each rule from Chapter 5 of Title 50 of the D.C. Code.
