Is There a Lemon Law in California? Coverage, Refunds, and Filing

Yes, California has a lemon law, and it is one of the strongest in the country. The California lemon law — formally the Song-Beverly Consumer Warranty Act, found at Civil Code sections 1790 through 1797.96 — requires a manufacturer to buy back or replace a vehicle it cannot fix after a reasonable number of repair attempts, and it makes the manufacturer pay your attorney fees if you win. That fee-shifting rule is why most lemon law claims cost the consumer nothing out of pocket to pursue.

Which Vehicles Are Covered

The law protects what Civil Code section 1793.22(e)(2) calls a “new motor vehicle,” but the term is broader than it sounds. It covers any car, truck, van, or SUV bought or used primarily for personal or household purposes and sold with the manufacturer’s express warranty still in effect. Dealer-sold used vehicles and demonstrators carrying the original manufacturer’s warranty are included, so a certified pre-owned purchase is not automatically disqualified.¹

Business-use vehicles qualify too, provided the gross vehicle weight is under 10,000 pounds and no more than five motor vehicles are registered to that business in California. The chassis, chassis cab, and drivetrain of a motorhome are covered; the living quarters are not. Motorcycles and vehicles never registered for on-road use fall outside the law.¹

What Actually Counts as a Lemon

A defect only triggers the law if it is a “nonconformity” — meaning it fails to meet the manufacturer’s express warranty and substantially impairs the vehicle’s use, value, or safety. A persistent stall, repeated brake failure, or an electrical fault that disables a safety system qualifies. A rattling trim piece or a cosmetic blemish generally does not, unless it creates a safety hazard or dramatically cuts the vehicle’s value.

The Lemon Law Presumption

Civil Code section 1793.22(b) gives buyers a shortcut. If one of the conditions below is met during the first 18 months after delivery or before the odometer reaches 18,000 miles (whichever comes first), the law presumes the manufacturer had a reasonable number of chances to fix the car and failed. The burden shifts, and the manufacturer must then prove the vehicle is not a lemon.¹

The same defect creates a condition likely to cause death or serious injury, and the manufacturer or its agents have tried to fix it at least twice.
The same defect has been subject to four or more repair attempts without being fixed.
The vehicle has been in the shop for repairs for a cumulative total of more than 30 calendar days since delivery. The days do not need to be consecutive.

The 30-day count can be extended only when repairs cannot be performed due to conditions beyond the manufacturer’s control, such as a parts shortage caused by a natural disaster.¹

A claim does not die if you fall outside this window. You can still sue; you simply carry the full burden of proving the manufacturer had enough chances to repair the car.

The Direct-Notice Requirement People Miss

For the two-attempt and four-attempt versions of the presumption, you must have notified the manufacturer directly at least once about the defect. Dropping the car at the dealership is not the same thing. This notice is only required if the manufacturer clearly disclosed the requirement in the warranty booklet or owner’s manual, so check the manual for a specific address or contact method. If no disclosure appears there, the direct-notice step may not apply to you.¹

Refund or Replacement: Your Choice

Civil Code section 1793.2(d)(2) gives the buyer, not the manufacturer, the choice between a replacement vehicle and a full refund.²

Buyback (Refund)

A refund covers the actual price paid for the vehicle, including transportation charges and manufacturer-installed options. On top of that, the manufacturer owes collateral charges — sales or use tax, license fees, registration fees, and other official fees — plus incidental damages like reasonable repair costs, towing, and rental car expenses tied to the defect.²

The manufacturer gets one deduction: a mileage offset for the use you had before the first repair attempt. Under section 1793.2(d)(2)(C), the formula is purchase price multiplied by miles at the first repair visit, divided by 120,000. On a $40,000 car brought in with 3,000 miles, the offset is $40,000 × 3,000 ÷ 120,000 = $1,000, which comes off your refund. Aftermarket accessories installed by you or the dealer are excluded from the refund; factory options are not.

Replacement

If you take the replacement option, the manufacturer must provide a new vehicle substantially identical to the one being replaced, with all the express and implied warranties that normally come with that type of new vehicle. Sales tax, license, registration, other official fees, and your incidental damages come with it.²

Attorney Fees and the Civil Penalty

This is the provision that makes the whole system workable. Civil Code section 1794(d) says that if you prevail, the court awards you attorney fees and costs based on the time your lawyer actually spent on the case. That is why most lemon law attorneys take these cases with no upfront cost to the client.³

When the manufacturer’s refusal to comply was willful, the court can add a civil penalty of up to two times your actual damages. On a $40,000 vehicle, that is potentially another $80,000. The penalty does not apply to class actions or to claims based solely on breach of an implied warranty.³

Section 1794(e) adds a parallel path. After the presumption events have occurred, you can send a written notice demanding the manufacturer buy back or replace the vehicle. If the manufacturer ignores the notice or does not act within 30 days, you become eligible for a civil penalty of up to two times your damages on top of the refund. This specific penalty does not apply where the manufacturer maintains a qualified third-party dispute resolution program.³

What to Document

Lemon law cases turn on paperwork. Start collecting from the first time something feels wrong.

Your purchase or lease agreement, which fixes the price, terms, and date that feed into refund and offset math.
Every repair order the dealership gives you. Check that the written description of the problem is accurate and consistent across visits. If the service writer phrases the symptom differently each time, four visits for one recurring defect can look like four unrelated minor issues.
Copies of any letters, emails, or online submissions you sent to the manufacturer about the defect. This is your proof of direct notice.
Your own calendar record of drop-off and pick-up dates. These establish how many days the car was out of service for the 30-day threshold.

If repair records are missing, ask the dealership for a complete warranty repair history. That report lists every visit, the mileage, and the work performed. The manufacturer’s address for legal notices is usually printed in the owner’s manual or warranty booklet.

How a Claim Moves Forward

Give the Manufacturer a Final Chance

Civil Code section 1793.2(b) requires that the manufacturer or its authorized facility be given the opportunity to repair the vehicle within 30 days, unless you agree in writing to a longer period.⁴ Send a written demand directly to the manufacturer describing the defect, the repair history, and the remedy you want. If the manufacturer ignores it, that letter supports a willful-violation argument later.

Arbitration

Some manufacturers run state-certified arbitration programs where an independent third party reviews the evidence and issues a decision. If the manufacturer has a certified program, you may be required to go through it before filing a lawsuit. The decision is non-binding on you — if the outcome is unsatisfactory, you can still take the case to court. The manufacturer is typically bound by the decision if you accept it.

Filing a Lawsuit

If arbitration does not resolve things, or if the manufacturer has no certified program, you can file a civil lawsuit. Many cases settle during litigation once the manufacturer’s exposure to attorney fees and the civil penalty becomes clear. Smaller claims can go to small claims court, though you would not be represented by an attorney there.

How Long You Have to File

California does not set a specific statute of limitations for Song-Beverly Act claims. Courts generally apply the four-year period under Code of Civil Procedure section 337, which covers actions on written contracts and obligations.⁵ The clock typically runs from the breach, often the date of the last failed repair attempt or the date the manufacturer refused to repurchase or replace the car. Waiting weakens the case even when you are still technically within the deadline, because repair records get harder to retrieve and the link to the warranty period grows murkier. Once you have hit the presumption thresholds, send your written demand promptly and get in front of a lawyer.
