All 50 states have a lemon law covering new vehicles with a substantial defect the manufacturer can't fix after a reasonable number of attempts — typically 3-4 repair attempts for the same issue, or 30 cumulative days out of service, within the first 1-2 years or roughly 12,000-24,000 miles, whichever comes first. If the defect qualifies, the remedy is usually a refund or replacement vehicle, minus a mileage-based usage deduction. Roughly half the states also extend some lemon-law coverage to used cars sold with a warranty. The federal Magnuson-Moss Warranty Act provides a backup legal path in every state regardless of the state law's specifics.

What makes a car a legal "lemon"
A vehicle generally must have a substantial defect — one that impairs use, value, or safety — that the manufacturer or its authorized dealer has had a reasonable number of chances to fix and failed. Cosmetic issues or defects you caused yourself (aftermarket modifications, accident damage) don't qualify. Most states define "reasonable number of attempts" as three or four tries at the same specific problem, or the vehicle being in the shop a cumulative 30 days or more, within a set time/mileage window from delivery.
How the process actually works
- Document every repair visit — date, described problem, what was done, mileage — starting from the very first issue.
- Give the manufacturer a final opportunity to repair, often via a formal notice, once you're near the state's attempt threshold.
- Many states require or offer a manufacturer-run arbitration program (like BBB AUTO LINE) as a required or optional step before filing suit.
- If arbitration fails or isn't required, you can file a lemon law claim in court; many state lemon laws include fee-shifting, meaning the manufacturer pays your attorney's fees if you win, which is why lemon-law attorneys often work on contingency.
What you actually get if you win
| Remedy | What it means |
|---|---|
| Refund (repurchase) | Manufacturer buys back the car, refunding purchase price minus a mileage-based usage offset |
| Replacement | A comparable new vehicle, sometimes with a smaller usage deduction |
| Cash settlement | A negotiated amount, often used to resolve a claim without a full buyback |
The mileage usage deduction is calculated using a formula tied to miles driven before the first repair attempt relative to the vehicle's expected lifespan (often 100,000-120,000 miles in state formulas) — meaning you won't get 100% of the purchase price back even in a successful claim.
Used cars and the used-car gap
Roughly half of US states extend some lemon law protection to used cars still under a manufacturer's original warranty or a qualifying used-car warranty; the rest leave used-car buyers to rely on the federal Magnuson-Moss Warranty Act and any state used-car-specific consumer protection statute, which tend to have weaker remedies than new-car lemon laws.
Missing the state's lemon law time/mileage window doesn't necessarily end your options — the Magnuson-Moss Warranty Act applies nationally to any written warranty and can support a claim even outside a specific state lemon law's deadline, though the burden of proof and remedy process differ.
Before you assume you have a case
This is general education, not legal advice — lemon law specifics differ meaningfully by state, and a consultation with a consumer-protection or lemon-law attorney (often free for an initial case review, since many work on contingency) is the right next step if you think your vehicle qualifies.
