lemon law
Lemon law refers to state and federal statutes that protect consumers who buy vehicles with substantial, unfixable defects that impair the car’s use, value, or safety. While every U.S. state has its own lemon law primarily covering new vehicles, the federal Magnuson-Moss Warranty Act can extend similar protections to used car buyers when a written warranty is involved. Some states—including New York, New Jersey, Massachusetts, Minnesota, Hawaii, Rhode Island, and Connecticut—have specific used car lemon laws with defined coverage periods and mileage thresholds.
Generally, a vehicle qualifies as a “lemon” when the manufacturer or dealer is unable to repair a covered defect after a reasonable number of attempts (often three to four) or when the car has been out of service for an extended period (typically 30 days or more). Qualifying remedies usually include a refund, replacement vehicle, or cash settlement.
Examples:
- A buyer purchases a certified pre-owned sedan with a 12-month dealer warranty. The transmission fails repeatedly, and after four failed repair attempts, the buyer pursues a claim under Magnuson-Moss and the state’s used car lemon law.
- A used SUV sold “as-is” without any warranty is typically not covered by lemon law, though it may still be subject to fraud or misrepresentation claims.
Why used car shoppers should care: Lemon law protection varies dramatically based on how the car is sold. Before buying, research the vehicle’s history using federal resources. The NHTSA maintains databases of recalls, consumer complaints, and New Car Assessment Program (NCAP) crash ratings at NHTSA.gov—entering the VIN can reveal unrepaired safety recalls that may strengthen a future claim. The EPA provides official fuel economy ratings at FuelEconomy.gov, which can help you identify misrepresentation if a seller’s claims diverge significantly from published figures.
Always get written warranties in writing, keep detailed repair records with dates and mileage, and document every dealer visit. If you suspect you’ve bought a lemon, contact your state attorney general’s office and consider consulting a consumer protection attorney—many handle lemon law cases on contingency, with fees recoverable from the manufacturer under Magnuson-Moss.
