California Lemon Law: How to Get a Refund or Replacement for a Defective Car
How many times does a car have to be repaired before it's a lemon in California?
Under California's Song-Beverly Consumer Warranty Act, a vehicle is presumed a lemon if the same defect has gone unrepaired after four or more attempts, if a safety-related defect persists after two or more attempts, or if the car has been out of service for repairs for more than 30 total calendar days within the warranty period. These thresholds apply within 18 months or 18,000 miles of delivery, whichever comes first.
Does California lemon law cover used cars?
California's lemon law, the Song-Beverly Consumer Warranty Act, covers used vehicles only if they were sold with an express dealer warranty. A used car sold "as is" with no warranty does not qualify. If a dealer provided a written warranty with the sale, the vehicle can potentially qualify for lemon law protection if it meets the repair-attempt or days-out-of-service thresholds under state law.
Can I get a full refund under California lemon law, or only a replacement?
California lemon law gives you the choice of either a full refund or a comparable replacement vehicle. A refund includes the original purchase price, taxes, registration fees, and finance charges paid, minus a mileage offset calculated based on miles driven before the first repair attempt for the defect. If the manufacturer refuses to comply in good faith, you may also be entitled to civil penalties up to twice your actual damages.
Do I need a lawyer to file a California lemon law claim?
You're not required to hire a lawyer, but California's Song-Beverly Act includes a fee-shifting provision that requires manufacturers to pay your attorney's fees if you win. Because of this, many consumer attorneys take lemon law cases on contingency, meaning no upfront cost to you. Given the complexity of the mileage-offset calculation and procedural requirements, consulting an attorney early is generally worth doing.
What should I do if the car manufacturer ignores my lemon law demand letter?
If a manufacturer doesn't respond adequately to a written lemon law demand, you can file a complaint with the California Department of Consumer Affairs' Arbitration Certification Program, pursue the manufacturer's own qualifying dispute-resolution process if disclosed in your warranty, or file a civil lawsuit in California Superior Court. The California State Bar's referral service at calbar.ca.gov can help you locate a consumer attorney who handles Song-Beverly cases.
Buying a new car and immediately watching it return to the shop, again and again, for the same problem is one of the more dispiriting consumer experiences California has to offer. What many drivers don't realize is that state law gives them real leverage in that situation. California's lemon law - formally the Song-Beverly Consumer Warranty Act - is among the strongest in the country, and it covers both new and many used vehicles purchased or leased in California.

What the Law Covers
The Song-Beverly Act applies to new vehicles sold or leased in California that come with a manufacturer's express warranty. It also applies to used vehicles, but only if they're sold with a dealer-issued warranty - a car sold "as is" with no warranty doesn't qualify. The law covers cars, trucks, SUVs, motorcycles, and even some motorized recreational vehicles. It does not cover vehicles purchased primarily for business use if the business owns more than five vehicles.
To trigger the law's protections, the defect has to substantially impair the vehicle's use, value, or safety. A persistent brake problem, a transmission that slips, an engine that keeps stalling - those qualify. A rattle that annoys you but doesn't affect how the car drives is a much harder case to make.
How Many Repair Attempts Are Enough
California law presumes a vehicle is a lemon if certain repair thresholds are met within the warranty period or within 18 months or 18,000 miles of delivery, whichever comes first. The thresholds, as the California Department of Consumer Affairs has described them: four or more repair attempts for the same defect, or two or more attempts for a defect that could cause death or serious injury, or the car has been out of service for more than 30 calendar days total due to repairs. Meeting one of these thresholds doesn't guarantee a win, but it creates a legal presumption in your favor that the manufacturer has to rebut.
The 30-day counter doesn't need to be consecutive. If the car spent 12 days in the shop in March and 20 days in August, you're past the threshold. Keep a running log from the start.
What You Can Get
If your claim succeeds, the manufacturer owes you either a replacement vehicle of comparable value or a full refund of the purchase price, including taxes, registration fees, and finance charges you've paid. The refund is reduced by a "mileage offset" for the miles you drove before the first repair attempt for the defect - a calculation formula set by state law. On top of that, manufacturers who don't promptly comply can be on the hook for civil penalties up to two times your actual damages, and in many cases they must cover your attorney's fees if you prevail. That fee-shifting provision is why consumer attorneys often take lemon law cases on contingency: they get paid if you win, not before.
What to Do Before You File Anything
Documentation is the whole game. Get every repair order in writing from the dealer, even for visits where they claim they couldn't reproduce the problem. Those "could not duplicate" notes are still repair attempts for purposes of the count. Keep copies of everything - invoices, communications, loaner-car records. Note every date the car was in the shop and when you got it back.
Before pursuing a legal claim, California law generally requires you to give the manufacturer a final opportunity to fix the vehicle if the manufacturer has established a qualified third-party dispute resolution process and disclosed it in the warranty materials. Many manufacturers have arbitration programs that meet this standard. You're not required to accept the arbitration result, and going through the process doesn't waive your right to sue, but skipping it when required can complicate your case. Check your warranty booklet to see if your manufacturer has a qualifying program.

How to Make a Claim
Start by sending a written demand to the manufacturer - not just the dealer - by certified mail with return receipt. State clearly that you believe the vehicle qualifies as a lemon under the Song-Beverly Act and specify whether you want a refund or a replacement. Keep a copy. Some manufacturers resolve claims at this stage to avoid litigation costs.
If the manufacturer doesn't respond satisfactorily, your options include filing a complaint with the California Department of Consumer Affairs' Arbitration Certification Program, pursuing the manufacturer's own dispute resolution process if it qualifies under state law, or hiring a consumer attorney to file a civil suit in California Superior Court. Given the fee-shifting provision, consulting an attorney who specializes in Song-Beverly claims is worth doing early - many offer free initial consultations and won't charge you upfront. The California State Bar's referral service at calbar.ca.gov can help you find one.
The statute of limitations for Song-Beverly claims is four years from the date of the breach, but don't treat that as an invitation to wait. Evidence gets harder to reconstruct, and repair records can become harder to obtain from dealers over time.
This is general information, not legal advice. The Song-Beverly Consumer Warranty Act's specific thresholds, mileage-offset formulas, and procedural requirements can be complicated and may have been amended; verify current rules with the California Department of Consumer Affairs at dca.ca.gov and consult a licensed California attorney for guidance specific to your situation.
