California lemon law: a consumer guide

Who is covered?

The Attorney General describes protection for most new vehicles purchased or leased in California with a manufacturer's new-vehicle warranty. There are special rules for qualifying business vehicles, motor-home components and active-duty service members.

Start with the purchase or lease agreement, registration, original delivery date and complete warranty. A vehicle marketed as new, used or certified may need a closer look under the statute's definitions. If you moved, bought across state lines or use the car for business, flag those facts before assuming the rules below apply.

Coverage periods and mileage

The familiar 18-month / 18,000-mile rule is a presumption window, not a blanket expiration of all warranty rights. It runs from delivery, whichever limit comes first.

Keep three dates separate: when the symptom began, when you reported it and when the facility attempted repair. Also keep the mileage for each event. An appointment booked before a deadline is not necessarily the same as a legally sufficient report. Preserve emails and work orders so the actual sequence can be checked.

Repair attempts and days out of service

Within that window, the presumption addresses four or more attempts for the same continuing problem; two or more for a continuing problem likely to cause death or serious bodily injury; or more than 30 cumulative calendar days out of service for warranty repairs. Exceptions and extensions matter.

These figures are not an automatic qualification score. The nature of the defect, whether it remains or recurs, and the applicable evidence rules still matter. Count actual visits and downtime separately. Keep raw drop-off and ready-for-pickup dates rather than relying on your own legal interpretation of which days should count.

Manufacturer notice and final repair

For the repair-attempt presumption, direct manufacturer notification can be required when the manufacturer properly disclosed that requirement in the warranty or owner's manual. Use the specified address. Separate pre-suit procedures now depend on whether the manufacturer elected the AB 1755 / SB 26 process; do not assume one notice rule fits every brand.

Read the warranty's contact section and the official instructions before sending anything formal. Include a factual description, repair chronology and vehicle identification in a private submission. Keep a complete copy and proof of delivery. Sending a complaint to a dealer, agency or online review site is not necessarily the same as notifying the manufacturer.

Arbitration and dispute programs

A qualified state-certified dispute program can matter to use of the statutory presumption. The Department of Consumer Affairs says consumers must request arbitration to claim that presumption when an applicable qualified program exists and the required notice was given. This is not the same as saying every warranty dispute must end in binding arbitration.

Identify the specific program, who administers it, what claims it accepts and whether participation or acceptance is required. Request the rules before applying. A customer-service case, manufacturer informal program, state hearing and binding contractual arbitration are different processes. Keep the application, acknowledgment, evidence packet and decision together.

What about used cars?

Do not assume a used vehicle qualifies merely because some original warranty time remains. The Attorney General now describes used vehicles for which a manufacturer's new-car warranty is issued with the sale. Coverage has been affected by court decisions; the precise warranty issued at your transaction matters.

Preserve the advertisement and any written promises made at sale. A service contract sold separately is not interchangeable with a manufacturer's warranty. A history report can supplement your file but does not establish legal coverage or replace a mechanical inspection. Our used-car guide explains how to separate those questions.

Deadlines: do not use the protection period as a filing date

California's procedures changed under AB 1755 and SB 26. Manufacturer election, claim type, notice and timing can change the analysis. Check the current statute and DCA election information before calculating a filing deadline; this guide does not supply a universal limitations date.

Make a calendar entry to verify timing now, not after another repair fails. Ask which event starts the clock, whether a particular notice must be received rather than sent and whether any program affects limitations. Do not assume informal negotiations, a pending parts order or a verbal assurance extend a legal deadline.

A practical next-step plan

First, address immediate safety. Ask a qualified repair professional about safe transport and avoid recreating a dangerous failure to produce evidence. A recall search may identify model-level campaigns, but a VIN check with NHTSA or the manufacturer is the better next step for an individual vehicle.

Second, create one repair file. Keep the transaction documents, complete warranty, every repair order, dated symptom notes and receipts. Use a one-page timeline as an index, not as a substitute for the original records. Include visits where the technician could not duplicate the problem and repairs that cost you nothing.

Third, match your timeline to the official state process. Identify the responsible manufacturer contact, any final repair opportunity and the correct dispute program. If a record is inaccurate, request a written correction rather than editing the invoice yourself. Keep your own observations separate from a technician's diagnosis.

Finally, review proposed outcomes carefully. A repurchase, replacement, trade-in and cash settlement are different transactions. Ask how loan or lease payoff, deductions, expenses, vehicle return and released claims are handled. Do not stop payments, cancel insurance or surrender the car solely because someone says a resolution is being considered. A licensed attorney can explain claim-specific obligations and settlement terms.
