California Lemon Law: How It Works and Your Rights

A vehicle that keeps returning to the repair shop may be more than an expensive inconvenience. California lemon law may require the manufacturer to replace or repurchase a vehicle when a warranty-covered defect substantially impairs its use, value, or safety and remains unresolved after a reasonable number of repair opportunities.

The governing statute is the Song-Beverly Consumer Warranty Act, primarily California Civil Code sections 1790 through 1795.8. Although repair counts matter, eligibility does not turn on a single universal number. The warranty, defect, repair history, vehicle type, manufacturer notices, and timing all affect the analysis.

What law governs California lemon law claims?

The Song-Beverly Consumer Warranty Act is California’s principal consumer warranty law, while the Tanner Consumer Protection Act creates a rebuttable presumption for certain qualifying new motor vehicles. A rebuttable presumption is a rule that shifts the burden of proof when specified facts are established but still allows the manufacturer to present contrary evidence.

Under California Civil Code section 1793.2, a manufacturer that cannot conform a qualifying new motor vehicle to its express warranties after a reasonable number of attempts must promptly provide replacement or restitution. An express warranty is the manufacturer’s written promise to repair specified defects during a stated period or mileage limit.

California warranty law generally protects vehicles bought or used primarily for personal, family, or household purposes. The statutory definition also reaches certain business vehicles weighing less than 10,000 pounds when no more than five vehicles are registered to the business in California. Qualifying lessees are treated as buyers for the new-motor-vehicle remedy.

Coverage commonly includes:

Qualifying new cars, pickup trucks, SUVs, vans, and EVs purchased or leased with the manufacturer’s warranty
Dealer demonstrators and certain dealer-owned vehicles sold with the manufacturer’s new-car warranty
The propulsion-related portion of a motor home, but not its living quarters
Some qualifying small-business vehicles

Used and certified pre-owned vehicles require a more careful analysis. A used vehicle may carry enforceable manufacturer, dealer, or CPO warranty rights, but an unexpired warranty alone does not automatically make every used vehicle a “new motor vehicle” for California’s statutory replacement-and-restitution provisions. The warranty issued with the sale, the identity of the warrantor, and the vehicle’s sales history must be reviewed.

What are the California lemon law requirements for a defect?

A potential claim generally requires a defect covered by an applicable warranty that substantially impairs the vehicle’s use, value, or safety. California law calls such a qualifying defect a “nonconformity.”

A defect may substantially impair use when it repeatedly prevents reliable transportation or makes important vehicle functions unavailable. It may impair value when a reasonable buyer would consider the unresolved problem important in deciding what to pay. A safety impairment may involve loss of braking, steering, propulsion, restraint systems, visibility, or another condition that creates a meaningful driving risk.

Potential warranty defects can include recurring engine or transmission failures, loss of power, braking problems, electrical faults, charging failures, battery-management errors, water intrusion, defective safety restraints, or persistent software-related drivetrain problems. The legal question is not whether a particular component appears on a list; it is whether the actual defect is covered, remains unresolved, and substantially affects the vehicle.

Cosmetic complaints, ordinary wear, maintenance issues, and minor concerns that do not meaningfully affect use, value, or safety are less likely to satisfy the standard. The manufacturer may also dispute coverage if the problem resulted from an accident, unauthorized modification, neglect, or unreasonable use after delivery.

A defect should ordinarily arise or be presented for repair while the relevant warranty applies. A claim does not necessarily disappear merely because the warranty expires while repairs continue, particularly when the defect was reported during coverage.

How many California lemon law repair attempts are required?

California law requires a reasonable number of repair opportunities, not the same fixed number in every case. The seriousness of the defect, whether repeated visits concern the same problem, and the vehicle’s cumulative downtime all matter.

The Tanner Consumer Protection Act establishes a rebuttable presumption when specified events occur within 18 months after delivery or the first 18,000 miles, whichever comes first. Under California Civil Code section 1793.22, the presumption may apply when:

The same defect likely to cause death or serious bodily injury has been subject to repair two or more times, and any required direct manufacturer notice was given.
The same non-safety defect has been subject to repair four or more times, and any required direct manufacturer notice was given.
The vehicle has been out of service for warranty repairs for a cumulative total of more than 30 calendar days, subject to extensions for conditions beyond the manufacturer’s control.

The repair visits do not have to satisfy these figures for a consumer to pursue a claim. The presumption is an evidentiary shortcut, not the entire California lemon law. A severe defect may make fewer opportunities reasonable, while intermittent or difficult-to-diagnose concerns may require a fact-specific evaluation.

Repeated visits should also be connected by consistent documentation. If one repair order says “vehicle stalls,” another says “loss of propulsion,” and a third records only “check-engine light,” the manufacturer may argue that the visits involved different conditions. Describe the symptoms, circumstances, frequency, and safety consequences accurately each time.

What records should you preserve during warranty repairs?

A strong claim requires records showing what happened, when the manufacturer’s authorized facility had an opportunity to repair it, and how long the vehicle was unavailable. Repair orders are especially important because they can establish the reported symptoms, mileage, dates, diagnostic work, parts replaced, and technician findings.

Keep copies of:

The purchase or lease agreement and financing documents
The manufacturer’s warranty booklet and owner’s manual
Every repair order, including visits marked “could not duplicate” or “operating as designed”
Check-in and pickup dates for each repair visit
Towing, rental-car, rideshare, and other relevant receipts
Emails, letters, text messages, app messages, and manufacturer case numbers
Photos or videos that capture warning lights, sounds, leaks, charging faults, or intermittent failures
Recall, service-campaign, and technical-service-bulletin notices you received

Before leaving a service appointment, confirm that the repair order describes the complaint you actually reported. Do not sign a document stating that the concern is fixed if it remains present; ask the advisor to record that the symptom continues or returned.

Maintain a simple chronology with the date, mileage, complaint, repair performed, and days out of service for every visit. Count calendar days carefully rather than estimating. A vehicle dropped off late one month and collected early the next can be easy to undercount without a written log.

How should you notify the manufacturer?

Consumers should give the manufacturer clear written notice using the address or email designated in the warranty materials and retain proof of delivery. Notice to a dealership creates a repair record, but direct notice to the manufacturer can serve a different legal purpose.

For the Tanner presumption’s two-attempt and four-attempt provisions, direct manufacturer notice is required only when the manufacturer conspicuously disclosed that requirement in the warranty or owner’s manual. Follow the specified instructions even if you are uncertain whether the disclosure is legally sufficient.

A written notice should identify:

Your name and contact information
The vehicle identification number, year, make, and model
The purchase or lease date and current mileage
A concise description of each unresolved defect
The dates and locations of warranty repair visits
The cumulative days out of service
Whether you are requesting repurchase or replacement

California’s procedures changed in 2025 for manufacturers that elect to use the process established by AB 1755 and SB 26. For an opted-in manufacturer, the process may require a written repurchase-or-replacement demand at least 30 days before filing suit. The California Department of Consumer Affairs maintains information about the current manufacturer-election framework; manufacturers that do not opt in remain subject to the existing California lemon law procedures.

Because the applicable process depends on the manufacturer and claim dates, do not rely on an old template or assume that a dealership complaint completed every notice requirement. Preserve the sent message, attachments, certified-mail receipt, delivery confirmation, and manufacturer response.

What remedies may California lemon law provide?

A qualifying consumer may seek restitution or a substantially identical replacement vehicle, but the availability and amount of any remedy depend on the evidence and applicable statute. A buyback, replacement, civil penalty, or settlement is never automatic or guaranteed.

For restitution, California Civil Code section 1793.2 generally includes the actual vehicle price paid or payable, manufacturer-installed options, transportation charges, sales or use tax, registration and other official fees, and qualifying incidental damages. Nonmanufacturer accessories installed by the dealer or buyer are generally excluded from the statutory calculation.

The manufacturer may deduct a statutory mileage offset for use before the first delivery of the vehicle for repair of the nonconformity that led to the claim. The new-vehicle formula is:

Actual price paid or payable × miles before the first qualifying repair attempt ÷ 120,000

The first relevant repair mileage can therefore materially affect a restitution calculation. It is not necessarily the mileage at the last repair visit or the date when the consumer first called the manufacturer.

Replacement ordinarily means a new vehicle substantially identical to the defective one, accompanied by the warranties normally provided with that model. California law permits the consumer to elect restitution instead; a manufacturer cannot force the consumer to accept a replacement.

Reasonable towing, repair, and rental-car expenses caused by the defect may qualify as incidental damages when supported by records. Consumers sometimes negotiate a cash-and-keep settlement and retain the vehicle, but that is a negotiated resolution rather than a guaranteed statutory result.

Under California Civil Code section 1794, a court may impose a civil penalty of up to two times actual damages when a consumer proves a willful failure to comply. Separate civil-penalty provisions can depend on notice, manufacturer conduct, and dispute-resolution procedures; penalties are not awarded merely because a vehicle had repeated repairs.

How do Magnuson-Moss claims and attorney-fee rules work?

The federal Magnuson-Moss Warranty Act can provide an additional claim when a warrantor fails to honor a written or implied warranty after receiving a reasonable opportunity to cure the defect. It does not replace California law, and federal recoveries are commonly cash settlements rather than guaranteed state-law buybacks or replacements.

The Act permits a prevailing consumer to seek reasonably incurred costs and attorney’s fees under 15 U.S.C. § 2310(d)(2), subject to the court’s determination. California Civil Code section 1794(d) likewise directs the court to award a prevailing buyer reasonably incurred costs and attorney’s fees based on actual time expended.

Stop Lemons handles matters on contingency, and cases are generally pursued without out-of-pocket attorney fees because federal law and California lemon law provide fee-shifting when the consumer wins. The written representation agreement controls the specific fee terms. Learn more about federal Magnuson-Moss protections and how they may complement a California warranty claim.

Legal deadlines can depend on the warranty, delivery date, discovery and repair history, manufacturer election, tolling rules, and relief requested. Waiting can make records harder to obtain and may jeopardize available claims, so a deadline analysis should be based on the specific vehicle and documents.

California lemon law FAQ

Does California lemon law always require four repair attempts?

No. Four attempts for the same nonconformity is one route to the Tanner presumption, but it is not a universal minimum. Two attempts may support the presumption for a condition likely to cause death or serious bodily injury, while more than 30 cumulative days out of service provides another route.

Does the 30-day rule mean 30 consecutive days?

No. California’s Tanner presumption refers to a cumulative total of more than 30 calendar days out of service for repair of nonconformities. The period may be extended when repairs cannot be performed because of conditions beyond the manufacturer’s control.

Can a used vehicle qualify under California warranty law?

A used or CPO vehicle may have enforceable warranty protections, but eligibility for new-vehicle restitution or replacement depends on how the vehicle and warranty fit California’s statutory definitions. The sales documents, warranty issuer, warranty terms, and vehicle history should be reviewed before drawing a conclusion.

Must I use the manufacturer’s arbitration program?

Not in every claim. Use of a qualified third-party process can affect access to the Tanner presumption when the consumer received timely written notice of the program, and post-2025 manufacturer elections can change other procedures. Review the current program rules before filing or accepting a decision.

How long does a California lemon law case take?

California law does not establish one universal duration for every claim. The repair record, manufacturer procedure, disputed facts, settlement discussions, arbitration, and litigation can all affect timing, so no specific completion date should be assumed.
