California’s lemon law does cover used cars, but only when a warranty is in place at the time of sale. A used vehicle still under the manufacturer’s original factory warranty gets the full protection of the Song-Beverly Consumer Warranty Act, including the statutory presumption that triggers a buyback or replacement. A used car sold with a dealer’s own written warranty is protected under a separate section of the same act, with the same core remedies but without the automatic repair-attempt thresholds. A used car sold with no written warranty at all is outside the lemon law entirely.
Which Used Cars Are Covered
Used Cars Still Under the Factory Warranty
If the manufacturer’s original warranty has time or mileage left when you buy the car, the law treats the vehicle essentially the same as a new one. California’s definition of “new motor vehicle” includes any vehicle sold with a manufacturer’s new car warranty, regardless of whether you are the first or second owner.1New York Codes, Rules and Regulations. 16 CCR 3396.1 – Definitions The California Department of Consumer Affairs confirms that covered vehicles include used cars, pickup trucks, vans, SUVs, and the chassis and drivetrain of motorhomes, as long as the manufacturer’s warranty is active.2California Department of Consumer Affairs. Arbitration Certification Program – California’s Lemon Law Q&A Certified Pre-Owned vehicles almost always fit here because they carry an extended manufacturer-backed warranty.
Used Cars With a Dealer Warranty Only
When the factory warranty has expired but the dealer provides its own written warranty at sale, Civil Code Section 1795.5 applies. That statute imposes the same obligations on a dealer selling used goods with an express warranty as the Song-Beverly Act imposes on manufacturers of new goods.3California Legislative Information. California Civil Code CIV 1795.5 If a dealer sells you a used car with a 90-day powertrain warranty and the transmission fails repeatedly during that period without a proper fix, you have a breach of warranty claim against the dealer.
The practical difference matters. Dealer-warranty claims do not get the Tanner Consumer Protection Act presumption described below, so proving the dealer had a reasonable number of repair chances takes more work.
Used Cars Sold With No Warranty
If you bought the car from a private party, or from a dealer who sold it as-is with no written warranty, the lemon law does not apply. The DCA states this plainly: a used vehicle with no manufacturer warranty is not covered.2California Department of Consumer Affairs. Arbitration Certification Program – California’s Lemon Law Q&A Implied warranty protections may still exist in some as-is situations (see below), but the lemon law’s repair-or-refund machinery does not.
What Counts as a Qualifying Defect
Not every problem makes a car a lemon. The defect must substantially impair the vehicle’s use, value, or safety.4California Legislative Information. California Civil Code 1793.2 A squeaky door panel or minor paint blemish will not qualify. A transmission that slips out of gear on the freeway, brakes that intermittently fail, or an electrical system that randomly shuts down the engine are the kinds of problems that meet the threshold.
Two things will defeat a claim no matter how serious the defect. The problem cannot have been caused by your own misuse or by unauthorized modifications, and you must report the defect while the warranty is still active. Discovering a problem the week after your warranty expires, with no earlier record of it, is too late.
How Many Repair Attempts Are Enough
California does not require you to let a dealer tinker with your car indefinitely. The Tanner Consumer Protection Act, codified in Civil Code Section 1793.22, creates a rebuttable presumption that the manufacturer has had enough chances to fix the vehicle if any of the following occur within the first 18 months of ownership or 18,000 miles, whichever comes first:5California Legislative Information. California Civil Code 1793.22
- The same defect has been repaired two or more times and still creates a condition likely to cause death or serious injury.
- The same defect has been repaired four or more times without being fixed.
- The vehicle has been out of service for repairs for a combined total of more than 30 calendar days.
One requirement trips people up. For the two-attempt and four-attempt thresholds, you must have directly notified the manufacturer about the defect at least once, not only the dealership service department. The manufacturer only has to tell you about this notification requirement if it is included in the warranty or owner’s manual, but meeting it either way strengthens your position.5California Legislative Information. California Civil Code 1793.22
This presumption applies only to vehicles covered by the manufacturer’s original warranty. For a dealer-warranty claim under Section 1795.5, you still need to show a reasonable number of repair chances, but without those automatic thresholds working in your favor.
What a Refund or Replacement Includes
If the manufacturer fails to repair the vehicle after a reasonable number of attempts, you choose between a replacement vehicle and a refund. You cannot be forced to accept a replacement.4California Legislative Information. California Civil Code 1793.2
A refund covers more than the sticker price. The manufacturer must reimburse the actual purchase price (including transportation charges and manufacturer-installed options), plus collateral charges like sales tax, license fees, registration fees, and other official fees. You can also recover incidental damages such as towing costs, rental car expenses, and repair bills you paid out of pocket.4California Legislative Information. California Civil Code 1793.2 Aftermarket accessories and dealer-installed add-ons are excluded.
The manufacturer gets to deduct a usage offset for the miles you drove before the first repair attempt for the defect. The formula: multiply the purchase price by the miles driven before that first relevant repair, then divide by 120,000.6California Legislative Information. California Civil Code CIV 1793.2 Reporting problems early keeps this deduction small.
Implied Warranties and As-Is Sales
When a dealer sells a used car with any express warranty, an implied warranty of merchantability attaches automatically. For used goods, that implied warranty lasts as long as the express warranty, with a floor of 30 days and a ceiling of three months.3California Legislative Information. California Civil Code CIV 1795.5 If no duration is stated, the implied warranty defaults to the three-month maximum. In practice, this means the car should work the way a reasonable buyer would expect for its age, mileage, and price.
California does allow dealers to disclaim implied warranties on as-is sales, but only with strict compliance. The dealer must attach a conspicuous written notice to the vehicle stating that the goods are sold as-is, that the buyer assumes all risk for quality and performance, and that the buyer will bear the full cost of any repairs.7Justia Law. California Civil Code Article 3 – Sale Warranties Skip any of those steps and the disclaimer may be invalid, leaving the implied warranty in place. Federal law separately requires dealers to post a Buyers Guide on every used vehicle disclosing whether it is sold as-is or with a warranty.8Federal Trade Commission. Buying a Used Car From a Dealer Keep your copy.
Documentation You Need
A lemon law claim lives or dies on paperwork. Start with your purchase contract, the written warranty (manufacturer or dealer), and the Buyers Guide. These establish that the vehicle was covered and on what terms.
Repair orders are your most important evidence. Every time the car goes in, make sure the service advisor writes down your exact complaint. “Customer states car is running rough” is far weaker than “customer states transmission slips out of third gear at highway speed, occurring daily since purchase.” If the written description does not match what you reported, ask for a correction before you leave. These documents establish both the number of repair attempts and the cumulative days the vehicle was out of service, mapping directly to the Tanner Act thresholds.
Keep a personal log with dates, mileage at each visit, and what you experienced. Hold onto rental car receipts, towing invoices, and any correspondence with the dealer or manufacturer. If you notified the manufacturer directly, keep a copy of that notice.
How to File a Claim
Once you have met the repair thresholds, send a written demand to the manufacturer requesting a buyback or replacement. Under California law, if you send that demand at least 30 days before filing a lawsuit, the manufacturer must respond with an offer of restitution or replacement within 30 days and complete it within 60 days.9California Department of Consumer Affairs. New Lemon Law Procedures – Arbitration Certification Program
If the manufacturer rejects the claim, California’s Arbitration Certification Program offers a free, informal process to resolve warranty disputes without court.10California Department of Consumer Affairs. Arbitration Certification Program Many manufacturers run their own certified programs. Arbitration is faster than litigation and costs the consumer nothing. If the result is unsatisfactory, you can still sue.
Attorney Fees and Willful-Violation Penalties
If you win a warranty claim, the court must award attorney fees based on the actual time your lawyer spent on the case.11California Legislative Information. California Civil Code 1794 This is why many lemon law attorneys work on contingency: the manufacturer pays the legal bill when the consumer prevails.
If you can show the manufacturer’s failure to comply was willful, the court can add a civil penalty of up to two times your actual damages on top of the refund or replacement.11California Legislative Information. California Civil Code 1794 A manufacturer that knows about a systemic defect and refuses buyback requests anyway has real exposure here.
Federal Backup Under Magnuson-Moss
The federal Magnuson-Moss Warranty Act applies to any consumer product sold with a written warranty, including used cars, and defines “consumer” to include anyone who receives the product during the warranty period, not just the original buyer.12Office of the Law Revision Counsel. 15 USC 2301 – Definitions A second or third owner is covered as long as the warranty is still in force.
Magnuson-Moss has its own fee-shifting provision: a consumer who prevails can recover attorney fees and court costs unless the court finds such an award inappropriate.13Office of the Law Revision Counsel. 15 USC 2310 – Remedies in Consumer Disputes Federal claims are often filed alongside Song-Beverly claims, giving the consumer two legal theories and more leverage in negotiations. The federal act also allows recovery of incidental and consequential damages like rental costs and lost use.
Filing Deadlines
California recently enacted new time limits under AB 1755. You must file your claim within one year after your express warranty expires, and no claim can be filed more than six years after the vehicle’s original delivery date, regardless of warranty status. Miss either deadline and you forfeit the lemon law presumption. For Magnuson-Moss claims, the general federal statute of limitations is four years from the date of purchase.
