California’s Lemon Law covers used cars, but only when the vehicle was sold with a warranty. If a dealer gave you an express written warranty, if the car came through a Certified Pre-Owned program, or if the original manufacturer’s warranty was still active at the time of sale, the Song-Beverly Consumer Warranty Act protects you. If you bought the car “as-is” or from a private seller, it almost certainly does not.
The statute that extends new-car protections to used vehicles is California Civil Code Section 1795.5. It applies the same framework to used goods sold with an express warranty, with one important shift: responsibility runs to “the distributor or retail seller making express warranties with respect to used consumer goods” rather than the original manufacturer.1Justia Law. California Code CIV 1795.5 – Sale Warranties In plain terms, if the warranty came from the dealer, the dealer is who you pursue. If the original factory warranty is still in effect, the manufacturer remains on the hook as if you had bought the car new.
Which Used Cars Qualify
Coverage turns entirely on warranty status at the moment of sale. Three situations qualify:
- The original manufacturer’s warranty has not yet expired on time or mileage. The factory remains responsible for warranted defects, and you have the same rights as the original buyer.
- The car was sold through a manufacturer-backed Certified Pre-Owned program. CPO vehicles carry their own express warranty, which brings them under Section 1795.5.
- The dealer issued its own express written warranty, even a short one. Since 2013, California has required “buy here, pay here” dealers to offer at least a 30-day or 1,000-mile warranty covering essential components, so even budget lots usually provide some coverage.
Any used car sold with an express warranty also carries an implied warranty of merchantability, which is a baseline guarantee that the car will work for basic transportation. Under Section 1795.5, that implied warranty runs as long as the express warranty, with a floor of 30 days and a ceiling of three months. If the dealer’s written warranty does not state a duration, the implied warranty defaults to the three-month maximum.1Justia Law. California Code CIV 1795.5 – Sale Warranties
Used Cars That Are Not Covered
When a dealer sells a used car “as-is,” the buyer waives the implied warranty of merchantability. California Civil Code Section 1792.4 allows this only if the dealer attaches a conspicuous written notice stating that the car is sold as-is, that the buyer assumes all risk for quality and performance, and that the buyer will pay for any necessary repairs.2California Legislative Information. California Code CIV – Sale Warranties Without that specific disclosure, the as-is label may not hold up. But when the dealer followed the rules, an as-is car has no warranty and no Lemon Law protection.
Federal rules reinforce this. Any dealer who sells more than five used vehicles in a 12-month period must post an FTC “Buyers Guide” window sticker disclosing whether the car is being sold as-is or with a warranty.3Federal Trade Commission. Dealer’s Guide to the Used Car Rule If a salesperson promised warranty coverage verbally but the Buyers Guide box says as-is, the written disclosure will usually control.
Private-party sales are almost never covered. Private sellers do not issue express warranties, and the Song-Beverly Act’s used-car provisions apply only to sales by distributors and retail sellers. The narrow exception is a privately sold car that still has an active manufacturer’s warranty, which can give the buyer a claim against the manufacturer for defects covered by that warranty. If a private seller lied about the car’s condition, you may have a fraud claim, but that lives outside the Lemon Law.
What Counts as a Lemon
Not every problem makes a car a lemon. The defect has to substantially impair the vehicle’s use, value, or safety. A squeaky door or a glitchy radio does not clear that bar. Brake failure, transmission problems, persistent stalling, and electrical faults that make the car unsafe do.4Justia. CACI No. 3204 – Substantially Impaired Explained The defect also cannot be something you caused through neglect, abuse, or unauthorized modifications.
The manufacturer or dealer also has to have had a reasonable chance to fix the problem and failed. California does not force you to accept a broken car after a single visit, but it also does not let you declare a lemon the first time a repair falls short.
How Many Repair Attempts Are Enough
California Civil Code Section 1793.22, known as the Tanner Consumer Protection Act, creates a rebuttable presumption that a vehicle is a lemon if any of the following has happened:5California Legislative Information. California Civil Code 1793.22
- The same defect has been repaired two or more times and could cause death or serious bodily injury if you keep driving.
- The same defect has been repaired four or more times without success.
- The car has been out of service for warranty repairs for a total of more than 30 calendar days, across any number of visits.
For the first two categories, you must have notified the manufacturer directly at least once about the problem, but only if the manufacturer clearly disclosed that requirement in the warranty or owner’s manual.5California Legislative Information. California Civil Code 1793.22
There is a wrinkle for used-car buyers. The Section 1793.22 presumption formally applies to “new motor vehicles” within 18 months of delivery or 18,000 miles, whichever comes first. For a used car sold with only a dealer warranty, the presumption may not automatically apply. You can still bring a Lemon Law claim without it, but the burden of showing that the number of repair attempts was reasonable stays with you. If the used car still carries its original factory warranty and the defect appeared inside the 18-month or 18,000-mile window, the presumption applies just as it would for a new-car buyer.
Steps to Take if You Suspect a Lemon
Document everything from the first sign of trouble. Save every repair order, invoice, text, and email. Keep a written log of dates, mileage at each visit, the symptoms you described, and what the shop said it did. This paper trail is the backbone of any claim.
Give the dealer or manufacturer a fair shot at the repair. Take the car back each time the problem returns, and resist the urge to switch to an independent mechanic out of frustration, because repairs performed outside the warranty network generally do not count toward the statutory thresholds.
When you believe enough attempts have failed, notify the responsible party in writing. For a used car still under its factory warranty, that is the manufacturer. For a used car under a dealer warranty, that is the dealer. Send the letter by certified mail with return receipt, describe the defect, list every repair attempt with dates and outcomes, and request a repurchase or replacement under the Song-Beverly Act.
Some manufacturers participate in the BBB AUTO LINE arbitration program, which is free and non-binding on the consumer; a decision from the arbitrator does not stop you from suing.6BBB National Programs. How BBB AUTO LINE Works You are not required to arbitrate before filing a lawsuit unless your warranty says so.
California’s Lemon Law requires the losing manufacturer or dealer to pay the buyer’s attorney fees when the buyer wins.7California Legislative Information. California Civil Code 1794 Because of that fee-shifting rule, most Lemon Law attorneys take cases on contingency and charge nothing unless you recover.
What You Can Recover
The most common remedy is a buyback. Under Section 1793.2, the refund must include the actual price you paid, sales and use tax, license and registration fees, and other official fees, plus incidental costs like towing, rental cars, and repair expenses you paid out of pocket.8California Legislative Information. California Civil Code 1793.2 Aftermarket accessories are excluded. If you financed the car, the manufacturer or dealer typically pays off the remaining loan balance directly to the lender and sends any surplus to you.
From that refund, the manufacturer or dealer gets to deduct a mileage offset for the miles you drove before the defect first appeared. The formula divides the miles you drove before your first repair attempt by 120,000, then multiplies by the purchase price. Drive 12,000 miles on a $30,000 car before the problem shows up and the offset is $3,000. The anchor date is when the defect first appeared, not when you finally gave up on repairs, which is one more reason early documentation matters.8California Legislative Information. California Civil Code 1793.2
You can request a replacement vehicle instead of a refund. For new-car claims, that means a substantially identical new vehicle with full warranties. For used-car claims under Section 1795.5, the replacement comes from the dealer, and what counts as “substantially identical” can look different. In practice, most buyers choose the buyback.
If the manufacturer or dealer willfully violates the Act, a court can add a civil penalty of up to two times your actual damages. “Willful” generally means knowing about the obligation and refusing to comply, not just moving slowly. Serving a written notice requesting compliance preserves this remedy; if the other side complies within 30 days of receiving the notice, the civil penalty drops away.7California Legislative Information. California Civil Code 1794
How Long You Have to File
You have four years from the date you discovered, or reasonably should have discovered, the defect to file a Lemon Law claim. The clock starts when you first become aware of the problem, not when you bought the car and not when repairs finally give out. Four years sounds long, but these cases take time to build, and waiting until the end of the window after months of back-and-forth with the dealer is one of the most common ways people lose otherwise strong claims.
