How Lemon Laws Work: Repair Attempts, Deadlines and Refunds
Every state has a lemon law for new cars, and the federal Magnuson-Moss Act fills gaps. The details that decide a case are repair counts, days out of service and deadlines.
A lemon law requires the automaker to replace a new vehicle or refund its price when a defect covered by the warranty substantially impairs its use, value or safety and the manufacturer cannot fix it after a reasonable number of attempts. Every state has a lemon law for new cars, and each sets its own repair counts, days-out-of-service limits and deadlines, so the rules for your case depend on where you bought or registered the car.
The federal Magnuson-Moss Warranty Act sits underneath the state laws. It lets you sue over a broken written warranty, including on some used cars that state lemon laws do not cover.
What makes a car a lemon?
A car is generally a lemon when it has a serious defect covered by the warranty that the automaker has not fixed within a set number of attempts or days during the state’s coverage period.
Most state laws share the same structure, though the numbers vary:
- The defect is substantial. It affects safety, use or value. A loose trim piece usually does not count; a stalling engine or failing brakes do.
- The repair attempts are exhausted. Many states set this at three or four attempts for the same problem, and fewer, often one or two, for a defect that can cause death or serious injury.
- Or the car spent too long in the shop. Many states use a cumulative total of about 30 days out of service for warranty repairs.
- It happened within the coverage window. This is often the first 12 to 24 months or a set mileage, and in some states the full warranty term.
Some states presume a car is a lemon once these thresholds are met, which shifts the burden to the automaker. Your state’s exact rule is on your state attorney general’s consumer protection site.
What does the automaker owe if the car is a lemon?
The usual remedy is a comparable replacement vehicle or a refund of the purchase price, including taxes and fees in many states, minus a deduction for the miles you drove before the first repair attempt.
| Remedy | What it usually includes | Common deductions |
|---|---|---|
| Refund (buyback) | Price paid, finance charges, sales tax, title and registration fees, in many states | A use allowance for miles driven before the defect was first reported |
| Replacement | A new, comparable vehicle | A use allowance in some states |
| Cash settlement | A payment while you keep the car | Negotiated, not set by law |
| Attorney fees | Many state laws and Magnuson-Moss let a winning consumer recover them | Not usually deducted |
A bought-back lemon is often resold, and many states require the title to carry a lemon or manufacturer buyback brand. That brand should appear on an NMVTIS title report, which our guide to free vehicle history checks explains.
How do I file a lemon law claim?
Build the repair record first, notify the automaker in writing, then use arbitration or court as your state requires.
- Report the defect to a franchised dealer every time it appears, and get a dated repair order for every visit, even if the dealer says it could not reproduce the problem.
- Count the attempts and the days the car was out of service.
- Read the warranty booklet. It names the automaker’s address for written notice and any dispute program.
- Send written notice to the manufacturer by a trackable method. Many states require this and give the automaker one final repair attempt.
- File for arbitration if your state or warranty requires it first.
- If arbitration fails or is not required, talk to a lawyer who handles lemon law cases. Many work for fees the automaker pays if you win.
Deadlines to file run from the delivery date or the end of the coverage period, and they differ by state. Check yours before the window closes. This page is general information; confirm the rules with your state attorney general or a licensed attorney.
Do I have to go to arbitration?
Sometimes. Some states require you to use a state-certified or state-run arbitration program before you can sue under the lemon law. Others leave it optional.
Many automakers run informal dispute programs, and the best-known third-party program is BBB AUTO LINE. Under federal rules, a program that a warranty requires you to use first must meet FTC standards, must be free to the consumer, and its decision does not bind you if you reject it. You can then go to court.
Arbitration is usually faster than a lawsuit. Bring your repair orders, a timeline and your written notice letter to the hearing.
What if my state’s lemon law does not cover my car?
Magnuson-Moss is the federal backstop. If a written warranty was breached, you can sue the warrantor for damages, and if you win, the court can award attorney fees.
That matters for cars a state law leaves out, such as many used cars, cars past the state coverage window but still under warranty, or defects that do not meet the state’s repair count. A few states, including New York, New Jersey and Massachusetts, also have used-car lemon laws or used-car warranty laws, mostly for vehicles bought from dealers.
A repeat defect can also be a safety issue. Report it to NHTSA; our guide to reporting a vehicle safety problem shows how. Complaints like yours are how investigations and recalls start.
Bottom line
A lemon law claim is won with paperwork: dated repair orders for every visit, a count of days out of service and a written notice to the automaker. If your car keeps going back for the same serious defect, check your state’s thresholds now, before the coverage period ends.
FAQ
How many repair attempts make a car a lemon?
Many states use three or four attempts for the same defect, or one or two for a defect that can cause serious injury. Your state attorney general’s site lists the exact number.
Do lemon laws cover leased cars?
Many state lemon laws cover leased vehicles as well as purchases. The refund in a lease case usually goes partly to you and partly to the leasing company.
Do lemon laws cover used cars?
Most state lemon laws cover new cars only, but a few states have used-car rules. Magnuson-Moss can apply to a used car sold with a written warranty.
Do I need a lawyer for a lemon law claim?
Not always, especially for arbitration. Many lemon law attorneys take cases because the law makes the automaker pay the consumer’s legal fees if the consumer wins.
