Overview

Key details to review

California’s Lemon Law—part of the Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) and the Tanner Consumer Protection Act—can cover used cars in specific situations. If a used vehicle is sold with a remaining manufacturer’s new-vehicle warranty, a certified pre-owned (CPO) manufacturer warranty, or a dealer/manufacturer express warranty, the law may require the manufacturer to repurchase or replace the vehicle if it cannot be repaired after a reasonable number of attempts. The law provides robust remedies, fee-shifting so the manufacturer pays your reasonable attorney’s fees if you win, and a usage deduction formula that limits how much is subtracted for the miles you drove before the first substantial repair attempt.

Who Qualifies

You may qualify under California’s Lemon Law for a used vehicle if:

Leased used vehicles can qualify on the same terms. Vehicles sold strictly “as is” without any manufacturer or dealer express warranty generally do not qualify under Song-Beverly, though other consumer or fraud remedies may still apply.

  • The used car was purchased or leased in California for personal, family, or household use; or it was purchased for business use where the business has five or fewer vehicles registered in California and the vehicle’s GVWR is under 10,000 pounds.
  • At the time of sale or lease, the car was covered by: The balance of the manufacturer’s new-car warranty (including powertrain or bumper-to-bumper); or
  • A manufacturer-backed CPO warranty; or
  • An express written warranty from the dealer or manufacturer (not just a third-party service contract).

How CA Law Applies

Key California rules for used vehicles:

This presumption can apply to qualifying used cars still under the original new-vehicle warranty and within the 18 months/18,000 miles window measured from the original new-car delivery date, not the used buyer’s date. Even if you are outside the presumption, you can still win by proving the manufacturer had a reasonable number of repair opportunities but failed to fix covered defects.

  • “New motor vehicle” definition includes certain used vehicles still covered by the manufacturer’s new-vehicle warranty when sold. If your used car carried any remaining new-vehicle warranty from the manufacturer at purchase, you may qualify for the Tanner Act presumptions.
  • Reasonable repair opportunities: California does not require a fixed number for every case, but the law presumes a vehicle is a lemon if, within 18 months of delivery to the first owner or 18,000 miles (whichever comes first): The problem likely to cause death or serious bodily injury was subject to two or more repair attempts by the manufacturer or its agents; or
  • The same non-safety defect was subject to four or more repair attempts; or
  • The vehicle was out of service for repair for a cumulative total of more than 30 days.
  • Repurchase (buyback): Refund of the price paid (including factory/dealer-installed options, sales/use tax, license/registration, and certain finance charges) minus a usage deduction.
  • Replacement: A comparable vehicle plus refund or payment of incidental damages, subject to the usage deduction.
  • Incidental/consequential damages: Towing, rental, reasonable repair-related expenses.
  • Civil penalty: Up to two times actual damages if the manufacturer willfully failed to comply.

Step-by-Step Process

  • Check if the used vehicle had remaining manufacturer new-vehicle warranty at purchase, a manufacturer CPO warranty, or a dealer/manufacturer express warranty. Obtain written warranty terms and the in-service date for the original new sale.
  • Focus on defects that substantially impair use, value, or safety (e.g., engine stalling, transmission slipping, brake or steering issues, repeated electrical failures, emissions faults that trigger limp mode).
  • Normal wear, damage from misuse/alterations, and non-warranty items (e.g., tires, aftermarket parts causing the issue) generally do not qualify.
  • Present the vehicle to an authorized dealer for the brand. Clearly describe symptoms. Request that every visit be opened as a warranty RO (repair order).
  • Keep copies of all ROs and invoices showing dates, mileage, complaint, diagnosis, and work performed. Never leave without paperwork.
  • Count each separate visit for the same defect. Track cumulative days the car was unavailable due to warranty repair.
  • Note the mileage at the first repair attempt for each defect to calculate any usage deduction later.
  • Send a dated demand letter or email to the manufacturer’s CA lemon law address (often listed in the warranty booklet) requesting repurchase or replacement under Cal. Civ. Code § 1793.2(d). Include VIN, purchase/lease date, current mileage, a concise repair history, and copies of ROs.
  • Request that the manufacturer identify any certified arbitration it offers in California and state whether it seeks one final repair attempt.
  • California law permits the manufacturer a final attempt to fix after you request a buyback. Document everything. If they decline or fail, your claim strengthens.
  • Some manufacturers have California-certified dispute resolution programs. Participation is optional, but a quick, free route for certain consumers. Results are not always binding on you and do not prevent filing suit if unsatisfied.
  • If the manufacturer refuses a fair resolution, file a complaint in California Superior Court in the county where the vehicle was purchased, registered, or where the defendant does business.
  • Typical causes of action: Song-Beverly (express warranty), implied warranty (if applicable), civil penalty for willful violation, and possibly Magnuson-Moss Warranty Act claims.
  • Seek remedies: repurchase or replacement, incidental/consequential damages, civil penalties, and attorney’s fees.
  • Do not modify or dispose of the vehicle. Keep all ROs, purchase/lease contracts, warranty booklets, communications, photos/videos of defects, and tow/rental receipts.
  • Many CA lemon cases settle pre-trial with a buyback. Ensure the settlement properly calculates the usage deduction and reimburses allowable collateral charges and incidentals.
  1. Confirm warranty coverage: Check if the used vehicle had remaining manufacturer new-vehicle warranty at purchase, a manufacturer CPO warranty, or a dealer/manufacturer express warranty. Obtain written warranty terms and the in-service date for the original new sale.
  2. Identify qualifying defects: Focus on defects that substantially impair use, value, or safety (e.g., engine stalling, transmission slipping, brake or steering issues, repeated electrical failures, emissions faults that trigger limp mode).
  3. Normal wear, damage from misuse/alterations, and non-warranty items (e.g., tires, aftermarket parts causing the issue) generally do not qualify.
  4. Use authorized repair facilities: Present the vehicle to an authorized dealer for the brand. Clearly describe symptoms. Request that every visit be opened as a warranty RO (repair order).
  5. Keep copies of all ROs and invoices showing dates, mileage, complaint, diagnosis, and work performed. Never leave without paperwork.
  6. Track repair attempts and days out of service: Count each separate visit for the same defect. Track cumulative days the car was unavailable due to warranty repair.
  7. Note the mileage at the first repair attempt for each defect to calculate any usage deduction later.
  8. Notify the manufacturer in writing: Send a dated demand letter or email to the manufacturer’s CA lemon law address (often listed in the warranty booklet) requesting repurchase or replacement under Cal. Civ. Code § 1793.2(d). Include VIN, purchase/lease date, current mileage, a concise repair history, and copies of ROs.
  9. Request that the manufacturer identify any certified arbitration it offers in California and state whether it seeks one final repair attempt.
  10. Allow a final repair opportunity if requested: California law permits the manufacturer a final attempt to fix after you request a buyback. Document everything. If they decline or fail, your claim strengthens.
  11. Consider state-certified arbitration: Some manufacturers have California-certified dispute resolution programs. Participation is optional, but a quick, free route for certain consumers. Results are not always binding on you and do not prevent filing suit if unsatisfied.
  12. Prepare to file in Superior Court: If the manufacturer refuses a fair resolution, file a complaint in California Superior Court in the county where the vehicle was purchased, registered, or where the defendant does business.
  13. Typical causes of action: Song-Beverly (express warranty), implied warranty (if applicable), civil penalty for willful violation, and possibly Magnuson-Moss Warranty Act claims.
  14. Seek remedies: repurchase or replacement, incidental/consequential damages, civil penalties, and attorney’s fees.
  15. Preserve evidence: Do not modify or dispose of the vehicle. Keep all ROs, purchase/lease contracts, warranty booklets, communications, photos/videos of defects, and tow/rental receipts.
  16. Negotiate or proceed to trial: Many CA lemon cases settle pre-trial with a buyback. Ensure the settlement properly calculates the usage deduction and reimburses allowable collateral charges and incidentals.

Common Mistakes

  • Relying only on dealer conversations and failing to notify the manufacturer in writing.
  • Leaving the dealership without a printed repair order or accepting “could not duplicate” without ensuring your complaint is documented.
  • Waiting too long—statute of limitations disputes can defeat otherwise strong claims.
  • Assuming “as is” kills every option—while it may block a classic lemon claim, express or implied warranty and fraud claims may still exist; have an attorney review.
  • Performing aftermarket modifications or tunes that give the manufacturer grounds to blame the defect on alterations.
  • Confusing a third-party service contract with a manufacturer/dealer express warranty; service contracts alone rarely trigger full Song-Beverly remedies.
  • Failing to calculate the mileage offset correctly or overlooking reimbursement for tax, license, registration, and incidental damages.
  • Trading in or selling the vehicle mid-claim, which can complicate remedies and evidence.
  • Not giving a final repair opportunity after a buyback demand when the manufacturer requests one.
  • Filing in the wrong venue or suing only the dealer when the manufacturer bears primary lemon liability.

What To Do Next

Gather your purchase/lease agreement, warranty booklet, complete repair history, and any communications with the dealer or manufacturer. Verify warranty status and the original in-service date to assess whether the Tanner presumption may apply. Send a written buyback demand to the manufacturer with supporting documents and be prepared to allow a final repair attempt if requested. Because California’s Lemon Law provides fee-shifting, consult a California lemon law attorney promptly—most offer free evaluations and no upfront fees. Acting quickly preserves your rights, improves your negotiation leverage, and helps ensure proper calculation of a repurchase or replacement under California law.
