Overview

Key details to review

California’s Lemon Law is primarily the Song-Beverly Consumer Warranty Act (California Civil Code §§ 1790–1795.8) and the Tanner Consumer Protection Act (Civil Code § 1793.22). Together, they require vehicle manufacturers to promptly repurchase or replace a vehicle that has a warrantied defect (a “nonconformity”) that substantially impairs use, value, or safety when the manufacturer or its authorized dealers cannot repair it after a reasonable number of attempts. Consumers who win can recover their attorneys’ fees and certain incidental damages; if the manufacturer willfully fails to comply, the court may award a civil penalty up to two times actual damages.

Who Qualifies

The following are typical California-specific eligibility criteria:

The “reasonable number of repair attempts” depends on circumstances, but California’s Tanner Act creates a presumption that a vehicle is a lemon if, within the first 18 months or 18,000 miles (whichever comes first): (1) the same safety-related defect likely to cause death or serious bodily injury has been subject to at least two repair attempts; or (2) the same defect has been subject to at least four repair attempts; or (3) the vehicle has been out of service for repairs for a cumulative total of more than 30 days. To use this presumption, consumers generally must have given the manufacturer direct written notice and a final opportunity to repair if the warranty requires it.

  • Vehicle type: Passenger cars, pickup trucks, SUVs, vans, and many light-duty vehicles. Motorhomes are partly covered (chassis, chassis cab, and drivetrain), but the living quarters are generally excluded. Motorcycles and some specialty vehicles may be covered under Song-Beverly as consumer goods depending on the warranty.
  • Warranty status: The defect must arise and be subject to the manufacturer’s new-vehicle warranty (including Certified Pre-Owned if the original new-vehicle warranty is still in effect or a manufacturer-backed warranty applies). Private-party sales without a manufacturer’s warranty generally do not qualify.
  • Where purchased/leased: Typically purchased or leased in California. Out-of-state purchases are usually not covered by California’s lemon provisions.
  • Use: Primarily personal, family, or household use. Certain small businesses also qualify if the vehicle’s gross vehicle weight is under 10,000 pounds and the business has no more than five vehicles registered in California.
  • Defect scope: The nonconformity must not be caused by abuse, neglect, unauthorized modifications, or accidents.

How CA Law Applies

If your vehicle qualifies and the defect is not fixed after a reasonable number of attempts, the manufacturer must either:

California’s mileage usage deduction is calculated as: (miles driven before the first repair attempt for the defect ÷ 120,000) × purchase price. Note: Negative equity from a trade-in is generally not reimbursable in a repurchase. After a manufacturer buyback, California law requires title branding as “Lemon Law Buyback” and written disclosure to any future transferee.

Special considerations:

  • Repurchase (buy back) the vehicle: Refund the “actual price paid or payable,” including most taxes, license, registration, and other official fees, plus incidental damages (e.g., towing, rental, rideshare) and payoff of the outstanding loan, less a mileage usage deduction; or
  • Replace the vehicle: Provide a new, substantially identical vehicle with no charge other than the mileage usage deduction and properly account for taxes, fees, and financing differences.
  • Electric and plug-in hybrid vehicles: High-voltage battery, propulsion, charging, thermal management, and related software defects may qualify if covered by the manufacturer’s warranty.
  • Implied warranty and used vehicles: California implies a warranty of merchantability; duration and claim theories differ from the express “lemon” remedies. Talk to counsel about timelines.
  • Limitations period: Many lemon claims must be filed within four years of the manufacturer’s breach of warranty (often tied to the first failed repair opportunity), but calculating deadlines is fact-specific.
  • Arbitration: Manufacturers may offer a California Department of Consumer Affairs (DCA) certified arbitration program. Using it is optional for consumers; you may accept or reject the decision and still sue. A certified program can streamline some claims and may affect the Tanner presumption’s notice requirement.

Step-by-Step Process

  • Verify that the defect manifested and was presented for repair during the manufacturer’s warranty period.
  • Check whether you’re within California’s limitations period to file suit (commonly up to four years from breach).
  • Collect purchase/lease contract, warranty booklet, all repair orders (ROs) and invoices, odometer readings, photos/videos, recall or TSB notices, and communications with the dealer/manufacturer.
  • Highlight dates and mileage at each repair attempt, the complaint stated, and the dealer’s findings.
  • Make an appointment with an authorized dealer. Clearly describe the defect and safety concerns in writing on the RO. Keep copies.
  • If the warranty booklet requires notifying the manufacturer, do so now and invite a final repair attempt.
  • Send written notice to the manufacturer’s designated address for lemon law disputes (listed in the warranty booklet). Use certified mail, return receipt requested.
  • Demand repurchase or replacement under Civil Code § 1793.2(d) and cite your eligibility under the Tanner Act presumption if applicable.
  • If the manufacturer participates in a DCA-certified program (e.g., BBB AUTO LINE), you may file there. It’s free to consumers and generally quicker than court.
  • Arbitration decisions are typically not binding on you unless you accept them; manufacturers are usually bound if you accept.
  • Confirm the refund math: price paid or payable; taxes, registration, and official fees; incidental damages; loan payoff; and the mileage offset tied to the first repair attempt for the defect.
  • Do not agree to nonstandard deductions (e.g., negative equity) or broad releases that waive unrelated claims without advice.
  • Under Civil Code § 1794(d), prevailing buyers recover reasonable attorneys’ fees and costs, which encourages manufacturers to resolve valid claims.
  • A lawyer can preserve your Tanner presumption, calculate your limitations period, and pursue civil penalties for willful violations.
  • Your attorney will file a complaint alleging violations of §§ 1793.2(d), 1793.22, and related provisions. Venue is typically proper where you bought/leased the vehicle or reside.
  • Expect written discovery, deposition(s), expert inspection, and a court-ordered mediation before trial in many counties.
  • For repurchase, the manufacturer pays the refund and loan payoff, you return the vehicle and sign DMV/transfer paperwork. The title will be branded “Lemon Law Buyback,” and the manufacturer must provide statutory disclosures to future transferees.
  • For replacement, confirm option equivalence, warranty carryover, taxes/fees reconciliation, and the usage deduction.
  • Continue making loan/lease payments until the payoff posts. Obtain written confirmation of payoff and account closure.
  • Keep a complete file of all documents and the settlement agreement.

Common Mistakes

  • Not documenting the complaint on the repair order in your own words; vague or inconsistent complaint descriptions weaken the claim.
  • Failing to give the manufacturer written notice and a final repair opportunity when the warranty requires it (undermining the Tanner presumption).
  • Waiting too long to act; limitations issues can arise even if you are still experiencing defects.
  • Altering the vehicle (tunes, lifts, aftermarket electronics) that the manufacturer can blame for the defect.
  • Accepting a “goodwill” trade-in or extended warranty in lieu of a statutory buyback, then signing a broad release you don’t understand.
  • Misunderstanding the mileage offset; it is tied to the mileage at the first repair attempt for the defect, not the last.
  • Assuming rental/towing expenses will be automatically reimbursed; you must claim and substantiate incidental damages.
  • Going to small claims to “save time” on a high-value case, thereby giving up statutory attorney-fee leverage and discovery tools.
  • Stopping loan/lease payments before the payoff clears, risking credit damage.
  • Overlooking special categories: EV battery and software faults, intermittent safety issues, and chassis-only coverage for motorhomes.
