What California Lemon Law Covers

New and used vehicles purchased from a dealer. The law protects buyers when a vehicle has a substantial defect that the manufacturer cannot repair after a reasonable number of attempts.

Used Car Coverage in California

Used vehicles are covered if purchased from a dealer with a warranty and under 18,000 miles or within 2 years of original delivery.

Qualifying Criteria

To qualify under California lemon law, a vehicle must meet at least one of the following thresholds within the coverage window:

CriterionCalifornia Threshold
Same defect repair attempts2 attempts
Out-of-service days (cumulative)30 days
Coverage window — time2 years from original delivery
Coverage window — mileage18,000 miles
State note: California has the strongest lemon law in the country. The 'two-repair rule' applies to serious safety defects — just two failed repair attempts can qualify the vehicle.

Arbitration and Dispute Resolution

California does not require arbitration before filing a lawsuit, but it can be faster and cheaper.

California has a state-certified arbitration program but you can go directly to court. Manufacturers must reimburse attorney fees if you win.

How to File a Lemon Law Claim in California

  1. 1

    Document every repair attempt

    Keep all repair orders with dates, mileage, and defect descriptions. You need written proof the same issue was reported and repaired multiple times.

  2. 2

    Track out-of-service days

    Record every day the vehicle was at the dealer for repairs. A cumulative total of 30 or more days can independently qualify the vehicle.

  3. 3

    Send written notice to the manufacturer

    Mail a certified letter to the manufacturer (not the dealer) describing the unresolved defect and requesting a final repair opportunity.

  4. 4

    Use the dispute resolution program

    California has a state-certified arbitration program but you can go directly to court. Manufacturers must reimburse attorney fees if you win.

  5. 5

    File with the state agency or court

    Contact the California Department of Consumer Affairs — Arbitration Certification Program or file in California civil court. Bring all repair orders, purchase documents, and correspondence.

  6. 6

    Collect your remedy

    A successful claim results in a full refund or replacement vehicle. The manufacturer pays attorney fees in most states.

Lemon Law and Bill of Sale

If your vehicle was repurchased under lemon law, the title will carry a "Lemon Law Buyback" brand in most states. When selling this vehicle, you must disclose the lemon history on the bill of sale and title. Hiding this information is fraud.

Buyers seeing a "Lemon Law Buyback" brand on a title should expect a significant price reduction and obtain a full mechanical inspection before purchasing.
