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

  1. 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.
  2. 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.
  3. 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.”
  4. 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.
  5. 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.
  6. 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).
  7. 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.
  8. 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.
  9. 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.
  10. 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.
