Overview
Key details to review
California’s Lemon Law—primarily the Song-Beverly Consumer Warranty Act (Civ. Code §§ 1790–1795.8) and the Tanner Consumer Protection Act (Civ. Code § 1793.22)—can protect buyers and lessees of used vehicles when those vehicles still carry a manufacturer’s warranty (including the remaining balance of the original “new car” warranty or a manufacturer-backed Certified Pre-Owned warranty). If a warrantied defect substantially impairs the vehicle’s use, value, or safety, and the manufacturer (through its authorized dealers) cannot fix it after a reasonable number of attempts, you may be entitled to a repurchase (buyback), replacement, or cash compensation—plus civil penalties for willful violations and payment of your attorney’s fees.
California’s law is distinct in several ways: it covers many used vehicles still under a manufacturer’s warranty, includes a powerful presumption (the “Tanner presumption”) during the first 18 months/18,000 miles from original delivery, protects certain small-business purchasers, and provides fee-shifting so consumers can hire a California lemon law lawyer without paying upfront.
Who Qualifies
You may qualify under California’s lemon law if all or most of the following apply:
Who typically does not qualify for a statutory buyback:
- The vehicle was bought or leased in California for personal, family, or household use; or it is a small-business purchase where the business has no more than five vehicles registered in California and the vehicle’s gross vehicle weight is under 10,000 pounds.
- The used vehicle had an active manufacturer’s warranty at the time problems began (e.g., remaining new-car warranty or a manufacturer CPO warranty). Dealer-only service contracts or third‑party warranties may support other claims, but the classic lemon law “buyback” remedy generally targets the manufacturer’s obligations.
- The defect is covered by warranty and substantially impairs use, value, or safety, and it persists despite a reasonable number of repair attempts by an authorized dealership.
- Repairs were sought from a manufacturer-authorized dealership (not just an independent shop), and you can document the repair visits and days out of service.
- Private-party purchases with no manufacturer warranty in effect.
- “As-is” sales with no express warranty from the manufacturer and no applicable dealer warranty that ties back to the manufacturer’s obligations.
- Vehicles modified or abused in a way that causes or contributes to the defect.
How CA Law Applies
Key California rules for used vehicles:
The presumption can apply to later owners if the vehicle is still within that initial 18 months/18,000 miles window. Outside that window, you can still win; you simply prove “reasonableness” without the statutory presumption.
- Song-Beverly Consumer Warranty Act (Civ. Code §§ 1790 et seq.): Requires manufacturers to repair warrantied nonconformities within a reasonable number of attempts and, if they cannot, to promptly repurchase or replace the vehicle (Civ. Code § 1793.2(d)). These duties apply to used vehicles still covered by the manufacturer’s warranty.
- Tanner Presumption (Civ. Code § 1793.22): Within the first 18 months or 18,000 miles from the vehicle’s original delivery to its first owner or lessee (whichever occurs first), a presumption of a “reasonable number” of repair attempts arises if: Two or more attempts for a defect likely to cause serious injury or death, or
- Four or more attempts for the same nonconformity, or
- The vehicle is out of service for warranty repairs for a total of 30 or more calendar days.
- Repurchase (restitution) includes the price paid (or lease payments), sales/use tax, license/registration, and incidental damages, minus a mileage offset calculated using the odometer reading at the first repair attempt divided by 120,000, multiplied by the purchase price (Civ. Code § 1793.2(d)(2)).
- Replacement must be substantially identical and without additional charge except for lawful mileage offset.
- Civil Penalties up to two times actual damages for willful failure to comply (Civ. Code § 1794(c)).
- Attorney’s Fees and Costs are recoverable if you prevail (Civ. Code § 1794(d)).
Step-by-Step Process
- Confirm Warranty Status: Determine whether the manufacturer’s original or CPO warranty was in effect when problems began. Gather the warranty booklet and any CPO documentation.
- Use an Authorized Dealer: Present the defect to a manufacturer-authorized dealership. Independent shops generally do not create the repair record needed to trigger the manufacturer’s lemon law duties.
- Describe Symptoms Clearly: Report the exact issues you experience. Ask the service advisor to capture your complaint verbatim on the repair order. Avoid characterizing defects as “normal” or “wear and tear.”
- Preserve All Records: Keep every repair order, invoice, and towing/rental receipt. Track dates in and out of service and odometer readings at each visit.
- Allow a Reasonable Number of Attempts: Return promptly if the problem persists. If the vehicle is unsafe, note that and request priority diagnosis. Keep using authorized service channels.
- Request Manufacturer Buyback/Replacement in Writing: When repair attempts are failing, send a written demand to the manufacturer (not just the dealer). Reference the defect, repair history, and your requested remedy (repurchase or replacement).
- Consult a California Lemon Law Lawyer Early: An attorney can evaluate eligibility, prevent missteps, value your claim (including civil penalties), and communicate with the manufacturer. Fee-shifting means you typically pay no out-of-pocket attorney’s fees if you prevail.
- Consider—but Don’t Rush Into—Arbitration: If offered a dispute program, discuss pros/cons with counsel. Some programs are nonbinding and can be useful; others may limit discovery or remedies.
- Negotiate or File Suit: Your lawyer will push for buyback, replacement, or a cash-and-keep settlement that reflects the defect’s impact and any penalty exposure. If the manufacturer stonewalls, file suit in a California court.
- Finalize Relief Safely: Review any release carefully. Ensure it includes proper restitution items (tax, license, incidental damages), correct mileage offset, and addresses loan payoff and negative equity issues.
Common Mistakes
- Using independent mechanics for warranty defects, which can undermine the repair record needed under Song-Beverly.
- Failing to document days out of service, odometer readings, and repeat symptoms—key to the Tanner presumption and overall proof.
- Waiting too long to seek help, risking statute-of-limitations defenses or loss of leverage.
- Accepting “no trouble found” without a detailed complaint recorded on the repair order.
- Continuing endless repairs rather than requesting buyback/replacement after multiple failed attempts.
- Modifying the vehicle (tunes, aftermarket parts) that give the manufacturer a causation defense.
- Assuming dealer promises equal manufacturer obligations; you must notify and pursue remedies with the manufacturer too.
- Entering “binding” arbitration or signing broad releases without legal advice.
- Trading in or selling the car mid-claim, which can complicate or reduce available remedies.
- Confusing recalls or maintenance items with warrantied nonconformities—recall completion alone does not bar a lemon claim if substantial defects persist.
What To Do Next
If you suspect your used car is a lemon in California, act quickly:
This information is for general educational purposes about California law. For advice on your situation, consult a licensed California lemon law attorney.
- Assemble your warranty, purchase/lease contract, all repair orders, and a simple timeline of problems.
- Schedule service with an authorized dealer and clearly restate the recurring defect; keep copies of updated repair orders.
- Send a written request to the manufacturer for buyback or replacement after repeated failures or significant days out of service.
- Contact a California lemon law lawyer to evaluate eligibility, potential civil penalties, and the best path (settlement, arbitration, or litigation). Under Civ. Code § 1794(d), the manufacturer may be required to pay your reasonable attorney’s fees if you prevail.
