Lemon Law: What to Do If You Bought a Defective Car

Updated:
By Sarah Kim · Reviewed for legal accuracy by Legal Editorial Team

If you bought a car that’s constantly broken, you may have a “lemon” on your hands. Lemon laws protect consumers who purchase or lease defective vehicles. Depending on your state and the severity of the defects, you may be entitled to a refund or replacement vehicle.

What Is a Lemon?

A lemon is a vehicle that has significant defects that substantially affect its use, safety, or value, despite repeated repair attempts.

A car is typically considered a lemon if:

The exact definition varies by state, but the general idea is: if your car keeps breaking down despite multiple repairs, you have a lemon.

Federal Magnuson-Moss Warranty Act

The Magnuson-Moss Warranty Act provides federal protection for defective vehicles. Key provisions:

  1. Implied warranty of merchantability — New cars are automatically warranted to be fit for ordinary use
  2. Duration: Typically covers defects discovered during the first year or first 12,000-18,000 miles
  3. Repair entitlement — The manufacturer must repair defects at no cost to you
  4. Failure to repair — If the manufacturer can’t repair a defect after reasonable attempts, they must refund or replace the vehicle

State Lemon Laws

Most states have their own lemon laws that are more protective than federal law. Key provisions vary but typically include:

How to Determine If You Have a Lemon

Check your state’s lemon law definition — Every state is different. Generally:

  1. Multiple repair attempts — Has the same problem been repaired 3-4 times?
  2. Multiple different defects — Have you had several different problems?
  3. Out of service time — Has the car been in the shop for 30+ days total?
  4. Safety defect — Is there an unfixed safety issue?
  5. Timeline — Are you within the coverage period (usually 1-2 years)?
  6. Mileage — Are you within the mileage limit (usually 12,000-18,000 miles)?

If you answer yes to most of these, you likely have a lemon.

Step-by-Step: Filing a Lemon Law Claim

Step 1: Document Everything

  1. Keep all repair records — Receipts from every repair attempt
  2. Note the date and mileage — When each repair was done
  3. Document the defect — What specifically is wrong
  4. Note the symptom recurrence — Does the same problem come back?
  5. Photo evidence — Take photos if there are visible defects
  6. Written records — Keep notes of conversations with the dealer

Step 2: Notify the Manufacturer

Most states require you to give the manufacturer notice of the defect and opportunity to repair:

  1. Write to the manufacturer’s lemon law coordinator — Find contact info on their website (usually customer service section)

  2. Send certified mail — This provides proof of delivery

  3. Include:

    • Your name and contact info
    • Vehicle identification number (VIN)
    • Purchase date and mileage
    • Detailed description of the defect(s)
    • List of all repair attempts with dates
    • Statement that you believe it’s a lemon
    • Request for refund or replacement
  4. Keep a copy — Save for your records

Sample letter:


[Your Name] [Your Address] [Date]

[Manufacturer Name] Lemon Law Coordinator [Company Address]

RE: Lemon Law Claim – Vehicle VIN [###]

Dear Sir or Madam,

I am writing to formally notify you that my vehicle, a [Year] [Make] [Model] with VIN [###], is a lemon under [State] lemon law.

Vehicle Details:

Defect Description: [Detailed description of the defect and how it affects use, safety, or value]

Repair History: The manufacturer has had 4+ repair attempts for this defect:

  1. [Date] - [Repair attempt description]
  2. [Date] - [Repair attempt description]
  3. [Date] - [Repair attempt description]
  4. [Date] - [Repair attempt description]

Despite these repairs, the defect persists, making the vehicle unfit for ordinary use.

Request: I am requesting [refund/replacement] under [State] lemon law. Specifically, I request [refund of $### less a deduction of $[###] for mileage, or replacement with an equivalent vehicle].

I expect a response within 30 days.

Sincerely, [Your Signature] [Your Typed Name]


Step 3: Wait for Manufacturer Response

The manufacturer has 30+ days (depending on state) to:

Step 4: File a Claim (If Needed)

If the manufacturer refuses or doesn’t respond, you can:

  1. Mediation — Some states require non-binding mediation first
  2. Arbitration — Some manufacturers have arbitration programs (you can usually opt out)
  3. Small claims court — For amounts under the small claims limit
  4. Lawsuit — Hire a lawyer and sue in civil court

Lemon Law Remedies

If you win a lemon law claim, you’re typically entitled to:

  1. Refund — Full purchase price back, minus:

    • Mileage deduction (typically $0.10-$0.25 per mile)
    • Down payment (sometimes included, sometimes not)
  2. Replacement — A new vehicle of equivalent or greater value

  3. Repairs — If the manufacturer successfully repairs the vehicle (not always available)

  4. Attorney’s fees — You may recover your legal costs

Example: You paid $30,000 for a car. You’ve driven 15,000 miles. Your lemon law deduction might be:

Frequently Asked Questions

Does lemon law apply to used cars? In most states, no. Lemon law protections typically cover only new vehicles — or, in a few states (California, Washington), used vehicles that still have an unexpired manufacturer’s or dealer warranty. If you bought a used car without a warranty, your options are narrower: the Magnuson-Moss Warranty Act, dealer fraud claims, and implied warranty claims depending on your state.

How many repair attempts before a car is a lemon? Typically three to four attempts for the same defect, or 30 or more cumulative days out of service — whichever comes first. The exact threshold varies by state. California requires two attempts for safety defects. Texas requires four. Some states count days out of service more favorably for consumers than others.

Can I get a full refund for a lemon? Yes, but with a mileage deduction. The refund is calculated as the purchase price minus a deduction for miles driven before the first repair attempt for the defect. The formula varies by state, but most use total miles at first repair divided by a “reasonable useful life” figure (typically 120,000 to 150,000 miles). On a $30,000 car with 5,000 miles at first repair and a 120,000-mile life, you would lose about $1,250 to the offset.

Do I need a lawyer to file a lemon law claim? Not always. In states that allow it, you can go directly to court or through an optional manufacturer arbitration program on your own. However, most lemon law attorneys work on contingency — meaning no upfront cost — because lemon law statutes in most states require manufacturers to pay your attorney fees if you win. It typically costs you nothing extra to have representation.

What is the difference between a lemon law buyback and a replacement? A buyback is a refund of your purchase price (minus a mileage offset). A replacement is a new vehicle of comparable or greater value. Manufacturers often prefer replacements because they cost less. As the consumer, you typically have the right to choose which remedy you want. If you accept a replacement, make sure it is the same model year or newer and of comparable or greater value.

What if the manufacturer refuses my lemon law claim? Document that you have met the statutory requirements (repair attempts, days out of service, written notice), then send a formal demand letter citing the applicable statute. If the manufacturer still refuses, file a lawsuit. In most states, manufacturers who refuse valid claims without a bona fide dispute face liability for attorney fees and in some states double or triple damages.
