Lemon laws protect consumers who purchase or lease defective vehicles ("lemons") that cannot be repaired after a reasonable number of attempts. Every state has its own lemon law with different requirements, and there is also a federal law — the Magnuson-Moss Warranty Act — that provides additional protections.
52 steps across 12 sections
1. Document Everything
- Keep all repair orders, work orders, and invoices
- Note dates the vehicle was dropped off and picked up (to calculate days out of service)
- Save all correspondence with the dealer and manufacturer
- Keep a log of symptoms: when, where, how often, and how the defect manifests
- Retain purchase/lease agreement and warranty documents
2. Allow Reasonable Repair Attempts
- Return to an authorized dealer for each repair attempt
- Clearly describe the same symptoms each time in writing
- Request that the repair order specifically documents your complaint
- Do not let the dealer dismiss or downplay the issue without documenting it
3. Notify the Manufacturer
- Send a written demand letter via certified mail (return receipt requested) to the manufacturer's customer service or lemon law department
- State the defect, the number of repair attempts, and the remedy you are seeking (replacement or refund)
- Many states require this written notice before you can pursue further action
- Keep a copy of the letter and the certified mail receipt
4. Participate in Arbitration (If Required)
- Many manufacturers have certified arbitration programs (e.g., BBB AUTO LINE)
- Some states require you to go through arbitration before filing a lawsuit
- Arbitration is typically free to the consumer
- The arbitrator's decision may be binding on the manufacturer but not on you (varies by state)
- If you are unsatisfied with the arbitration result, you may still have the right to file a lawsuit
5. Consult a Lemon Law Attorney
- Most lemon law attorneys offer free case evaluations
- Under most state lemon laws and the Magnuson-Moss Act, the manufacturer pays your attorney's fees if you prevail
- This means you typically pay nothing out of pocket for legal representation
- An attorney can assess your case strength and navigate state-specific requirements
6. File a Lawsuit (If Necessary)
- If arbitration fails or is not required, your attorney will file a civil lawsuit
- Remedies typically include:
- Replacement: A comparable new vehicle
- Refund: Full purchase price minus a reasonable offset for use (based on mileage at first repair attempt)
- Cash settlement: Negotiated amount
- Under the Magnuson-Moss Act, you can also recover attorney's fees and court costs
7. What Counts as a "Substantial Defect"
- Engine failure or persistent stalling
- Transmission problems (slipping, grinding, failure to shift)
- Brake system malfunctions
- Electrical system failures
- Steering defects
- Persistent warning lights that cannot be resolved
- Safety-related issues (airbag malfunctions, seatbelt issues)
8. What Typically Does NOT Qualify
- Minor cosmetic defects (small scratches, paint chips)
- Normal wear and tear items
- Issues caused by owner modifications or misuse
- Defects in aftermarket parts
9. Coverage
- New vehicles only: Most state lemon laws cover only new vehicles purchased or leased with a manufacturer's warranty
- Used vehicles: A few states (e.g., Connecticut, Massachusetts, Minnesota, New Jersey, New York, Rhode Island) have used-car lemon laws
- Leased vehicles: Most states cover leased vehicles under their lemon law
10. Reasonable Repair Attempts (Common Thresholds)
- 3—4 repair attempts for the same defect (most common threshold)
- 1—2 attempts for a safety defect that could cause death or serious injury
- 30 cumulative days out of service for repairs (regardless of the number of attempts)
- Some states use a combination of these criteria
11. Time/Mileage Limits (Lemon Law Rights Period)
- Typically first 12—24 months or 12,000—24,000 miles (whichever comes first)
- California: 18 months or 18,000 miles
- New York: 2 years or 18,000 miles
- Some states use the full warranty period
12. Statute of Limitations for Filing
- Varies from 1 to 6 years after the defect was discovered or should have been discovered
- California: 4 years from discovery of the defect
