What Is Lemon Law? Who Qualifies, How It Works & What You Can Get
A short primer on the federal Magnuson-Moss Warranty Act and the state lemon laws that sit on top of it. Walks through who qualifies, how repair-attempt counts and out-of-service days are measured, and the three outcomes most claims end with: a buyback, a replacement, or a cash settlement.

Lemon law is a consumer-protection framework that sits on two levels: the federal Magnuson-Moss Warranty Act of 1975 and the state lemon law statutes that build on it. Magnuson-Moss covers any consumer product sold with a written warranty. Each state then layers vehicle-specific protections on top, with its own thresholds for what makes a vehicle a lemon.
Across most states, three triggers matter. First, repeat repair attempts for the same defect — usually four for non-safety issues, two or three for safety-related defects like brakes or steering. Second, total days out of service — typically 30 cumulative calendar days within the warranty period. Third, the defect must substantially impair the use, value, or safety of the vehicle. Recurring transmission failures, repeated check-engine fault codes, electrical glitches that disable safety features — these are the ones that show up most often in qualifying claims.
Three remedies are written into nearly every state lemon law. A buyback returns the purchase price minus a usage offset pegged to mileage at the first reported defect. A replacement vehicle gives you a comparable model at no out-of-pocket cost. A cash-and-keep settlement pays a check while you keep driving the car. Which one fits depends on your state, your repair history, and the manufacturer's posture going into negotiation.
Most claims also reimburse incidentals — towing, rental cars, days missed at work — and the manufacturer pays your attorney's fees if your case wins, under the fee-shift rule built into nearly every state statute.
