If the manufacturer cannot repair a defect that substantially impairs the use, value or safety of your vehicle after a reasonable number of attempts, it must promptly replace the car or refund you, and you get to elect the refund instead of a replacement (Civ. Code § 1793.2(d)(2)). That choice is yours. In most states it belongs to the manufacturer.
Three provisions do the heavy lifting
A civil penalty of up to two times your actual damages where the failure to comply was willful (Civ. Code § 1794(c)). Damages plus a full penalty is why people say California pays triple. The penalty itself is two times, not three.
Your legal fees come out of the manufacturer, not your settlement. A buyer who prevails recovers costs and reasonable attorney fees (Civ. Code § 1794(d)).
A hard 30 day repair rule. Once you hand the car over, the conforming vehicle has to be tendered within 30 days unless you agree otherwise in writing (Civ. Code § 1793.2(b)). What to do when day 31 arrives is in our guide on how long a dealership can hold your car for repair.
One precondition to know about
If your manufacturer runs a state certified dispute resolution programme and gave you timely written notice of it, you cannot lean on the lemon law presumption until you have used that programme first (Civ. Code § 1793.22(c)). The Department of Consumer Affairs certifies these and publishes which brands use which one. Several major brands, including Honda, have no certified programme at all, which means there is no arbitration step to clear.
The buyback remedy covers new vehicles bought or leased in California for personal, family, or household use, and business vehicles under 10,000 pounds where the business has no more than five vehicles registered in this state (Civ. Code § 1793.22(e)(2)). Leases count. Demonstrators count. Two categories most sites list do not.
What is in, and the detail that decides it
New car, truck, SUV or van, personal use or the five vehicle business rule. In.
Motor home, chassis and propulsion portion only. The living quarters are out.
Motorcycle, Out. The statute expressly excludes motorcycles from the buyback definition, whatever other sites tell you. A defective motorcycle still supports warranty claims under section 1794 and the federal act; it just does not use this specific remedy.
Used car carrying the balance of the factory warranty. Out since 2024, covered in the used car row below.
Full-time active duty service members stationed or living in California when they bought are protected by California’s lemon law even if the vehicle was bought or registered in another state (California Attorney General). Drove one home from a base in Texas? Do not assume you are stuck with Texas law.
Three things have to be true. The defect substantially impairs use, value, or safety. It is covered by the manufacturer’s express warranty. And the manufacturer has had a reasonable number of attempts. California then hands you a shortcut on that third element, the lemon law presumption.
The presumption, in the statute’s own words
Inside 18 months from delivery or 18,000 miles, whichever comes first, any one of these creates a rebuttable presumption that the manufacturer has had enough attempts (Civ. Code § 1793.22(b)).
The same defect has been subject to repair four or more times and still exists.
The defect is likely to cause death or serious bodily injury and has been subject to repair two or more times.
The vehicle has been out of service for repair for more than 30 calendar days in total. Different faults all count toward the same 30 days.
The written notice trap
The first two triggers carry a condition. You must have directly notified the manufacturer at least once, and that only applies if the manufacturer clearly and conspicuously disclosed the requirement in the warranty or owner’s manual. Read that twice, because it is the most common own goal in California claims. A word with a service advisor is not notice to the manufacturer. A dated email or letter to the address in the warranty booklet is. Put it in writing today; it takes ten minutes, and the buyback section shows why it can be worth thousands.
Miss the 18-month or 18,000-mile window and the claim is not dead. The presumption is a shortcut, not the law. Outside it, you win by proving a reasonable number of attempts, which our guide on how many repairs it takes before lemon law applies covers. If the dealer keeps saying it is fixed, get no fault found printed on the order and read what happens when a dealership cannot fix your car.
California now runs two lemon law tracks, and the one you are on decides how long you have to file. Assembly Bill 1755, signed September 29, 2024, added a new chapter with a much shorter deadline and a mandatory pre-suit notice. Senate Bill 26, signed April 2, 2025, then made that whole chapter optional for manufacturers.
A manufacturer opts in by filing notice with the Arbitration Certification Program at the Department of Consumer Affairs. The election is irrevocable for five calendar years, and the state publishes the list of who opted in by December 15 each year (Code Civ. Proc. § 871.29).
If your manufacturer did not opt in
The older framework governs. A lawsuit for breach of a written warranty is generally governed by the four-year period in Code of Civil Procedure section 337, subject to the delayed discovery rule.
If your manufacturer opted in
You must file within one year after the applicable express warranty expires, and never later than six years after original delivery (Code Civ. Proc. § 871.21). You also have to send a written notice with your name, VIN, and repair history at least 30 days before seeking civil penalties, and hold the car while you do (Code Civ. Proc. § 871.24). Mediation is scheduled early, and most discovery is stayed until it ends. The remedies do not change. AB 1755 changed procedure, not what you can recover.
How to find out which track you are on
Check the published list at the Department of Consumer Affairs, with the background at its new lemon law procedures page. That is the only authoritative answer. When we checked it on August 10, 2026, the page carried the heading and no manufacturer names beneath it. You can also read your own paperwork, since a manufacturer selling a new car now has to tell you which procedures govern it. Practical rule that survives either answer: do not wait. If your warranty expired in the last year, plan around the shorter clock, because being early costs nothing and being late ends the claim.
California does not publish a list of qualifying defects. It publishes a test. A defect qualifies when it substantially impairs the use, value, or safety of the vehicle to you (Civ. Code § 1793.22(e)(1)). Two questions get you most of the way. Does it stop you using the car the way you bought it to be used, and would a buyer knock money off if they knew?
Faults that usually clear the bar
Engine failure, stalling, or persistent loss of power. Owners chasing this often land on our GM 6.2L L87 engine lawsuit page.
Transmission slipping, shuddering, or refusing a gear, including CVTs. See Nissan CVT transmission problems.
Brake failure, a long pedal, or driver assistance braking for cars that are not there. The Honda phantom braking litigation is the best documented example.
Steering that wanders or loses assist, and electrical or software faults that take out the dashboard, infotainment or driver assistance, including a problem introduced by an over-the-air update.
Battery, charging and range faults on an electric vehicle. Software is warranty-covered content and a car that will not charge is not a cosmetic complaint.
Oil consumption bad enough to top up between services. See the Ford F-150 oil consumption litigation.
Air conditioning failure, which in a Central Valley July stops being about comfort.
Faults that usually do not: trim rattles, paint blemishes, a squeaky seat rail. Anything cosmetic that does not touch how the car drives or what it is worth.
One point people miss. More than 30 cumulative days out of service triggers the presumption on its own, whatever the faults were. Check your open recalls while you are at it, since recall repairs park cars for weeks (NHTSA). Our manufacturer pages collect defect patterns by brand, including Tesla.
A buyback returns the actual price you paid, plus collateral charges such as sales tax, licence and registration, plus incidental costs such as towing and rental, minus one deduction for the miles you drove before your first repair visit (Civ. Code § 1793.2(d)(2)). That deduction is the only thing between you and a full refund, and it is fixed by a formula.
The mileage offset formula
Offset = purchase price multiplied by (miles at your first repair visit divided by 120,000).
On a $48,000 SUV first taken in at 6,200 miles, the offset is $2,480. On the same SUV first taken in at 19,000 miles, it is $7,600. The difference is $5,120, and the only variable is how early you complained. The number that matters is the odometer on your first visit, not today’s mileage. Every mile after that is free. You can sanity check yours with our lemon law buyback calculator.
One offset the manufacturer cannot take
If the manufacturer’s own refusal to buy the car back forced you to trade it in or sell it, the trade-in value and the sale proceeds do not reduce your restitution. The California Supreme Court settled that in Niedermeier v. FCA US LLC (2024) 15 Cal.5th 792. A driver who gave up on a dangerous car after repeated repair attempts does not owe the manufacturer a discount for having refused to fix it.
Leases follow the same logic on different numbers, since what you paid is payments plus the down payment. If you are in one, start with what to do about a leased car with mechanical problems.
You can normally keep driving it, and the extra miles do not raise the offset, because that number is frozen at your first repair visit. Selling or trading it is the decision that needs a conversation first, because on the opted in track possession of the car is a statutory condition at two specific moments (Code Civ. Proc. § 871.24).
When you send the pre suit notice, you have to have the car.
For 30 days after they receive it. If no offer arrives inside those 30 days you can then sell and still pursue civil penalties. If an offer does arrive, hold the car for the full 60 days.
If you sell, you have to give the buyer written notice of why you asked for a buyback and of any pending case, or the civil penalty goes away.
If you file without sending notice at all, you must still have the car when the complaint is filed, and you give up civil penalties.
Already traded it in? Not automatically fatal, because of Niedermeier above. But get the file read before the car leaves your driveway. Thinking of handing it back to the dealer instead? Read what actually happens when you try to return a car after buying it first.
This is where California changed most and where the internet has not caught up. On October 31, 2024, the California Supreme Court held that a used vehicle carrying the unexpired balance of the original factory warranty is not a new motor vehicle for the refund or replace remedy. The new car warranty has to be issued with the sale (Rodriguez v. FCA US, LLC (2024) 17 Cal.5th 189). The decision disapproved Jensen v. BMW, the 1995 case most used car lemon law pages are still quietly built on.
So if a page tells you your three-year-old truck with warranty left gets the California buyback remedy, that page is out of date. What used buyers actually have is four other routes, and one is brand new.
Certified pre-owned or any used car where the new car warranty was issued with the sale: That fits the definition, so the full refund or replace remedy is available.
Dealer express warranty on a used car (Civ. Code § 1795.5): You claim against the selling dealer, not the manufacturer, and it carries an implied warranty of merchantability lasting between 30 days and three months.
Magnuson-Moss Warranty Act: Federal, no new versus used distinction, with its own fee shifting.
Dealer misrepresentation: about condition or history, which supports rescission and damages under California consumer protection law.
The CARS Act, from October 1, 2026: Senate Bill 766, the California Combating Auto Retail Scams Act, replaces the old optional cancellation agreement with a mandatory three calendar day right to cancel a used purchase or lease priced at $50,000 or less, and forces dealers to advertise a real total price. It is the first law of its kind in the country. If you are buying used in California this autumn, that date is worth more than any warranty upsell on the desk.
For the wider picture, our guides on lemon laws for used cars and the federal lemon law for used cars show how these routes combine in practice.
California lemon law is a state law. It reads the same in Redding as in Chula Vista, and none of it turns on which dealer sold you the car. A claim runs on repair orders, warranty documents, and dated correspondence, so nothing about it requires you to sit in an office.
We take California enquiries from Los Angeles, San Diego, San Francisco, San Jose and Fresno, and from Sacramento, Riverside, Long Beach, Bakersfield, Anaheim, Oakland, Alhambra, Rosemead, Pasadena and everywhere between.
Bought in one city and moved to another? Bought out of state and registered here? Neither changes your repair history. Both can change which state’s statute applies, which is a two-minute conversation worth having before you file. If your purchase is anchored elsewhere, start with Arizona, Nevada, Texas, Florida, New York, or Illinois, or the full state lemon law directory.
We work warranty and vehicle defect claims full time. Not personal injury with a lemon law page bolted on the side.
No fee unless you win. California shifts fees, so a prevailing buyer recovers costs and reasonable attorney fees from the manufacturer (Civ. Code § 1794(d)). The full picture is in our guide to what lemon law attorneys cost.
We read the file before we promise you anything. Repair orders, warranty terms, the mileage at every visit, and the dates of your written complaints. The answer lives in those documents.
We work to the statute, not a script. Every claim on this page cites the California section it came from, so you can check us.
