Overview: Repeated Vehicle Defects in California

Plain-English guide to your Lemon Law options

If your car keeps having the same issue and the dealer cannot fix it under warranty, California’s Lemon Law may force the manufacturer to repurchase or replace it.

This law applies to many new cars and some used or leased vehicles sold or registered in California.

  • Covers substantial defects that affect use, value, or safety.
  • Applies when the manufacturer had a reasonable number of repair attempts.
  • Remedies include buyback, replacement, or a cash settlement to keep the car.

Who May Qualify

Key facts that matter under California law

Your vehicle must be covered by a manufacturer’s new-vehicle warranty or a remaining certified pre-owned or dealer warranty when the problems start.

Even if you miss the “presumption” window, you can still win if records show repeated, unsuccessful repairs.

  • Tanner Presumption (first 18 months/18,000 miles): 2+ repair attempts for a serious safety defect, 4+ for other defects, or 30+ total days out of service.
  • Used vehicles can qualify if defects arise while a manufacturer or dealer warranty is active.
  • Small businesses may qualify if the vehicle is under 10,000 lbs GVWR and the business owns fewer than five vehicles.
  • Exclusions: abuse, unauthorized modifications, or damage from accidents are not covered.

How California Law Works

Song-Beverly Act and the Tanner Consumer Protection Act

You must give the manufacturer or its authorized dealer a reasonable chance to fix the defect. Keep every repair order.

If your claim succeeds, buyback typically includes your down payment, monthly payments, taxes, registration, and certain incidental costs, minus a mileage offset.

California allows attorney’s fees for consumers, and most automakers offer state-certified arbitration overseen by the Department of Consumer Affairs’ Arbitration Certification Program.

Deadline: Most lemon claims must be filed within four years from when you knew the warranty was breached.

  • Mileage offset reduces the refund based on miles driven before the first repair attempt.
  • Incidental damages can include towing, rental, rideshare, and diagnostic fees.
  • Arbitration is usually faster and free, but you are not required to accept an unfair decision.

Step-by-Step: How to File a California Lemon Claim

From documentation to demand

Follow these steps to protect your rights and build a strong record.

If the manufacturer will not resolve your claim informally, you can use certified arbitration or file a lawsuit.

  • Use clear, consistent descriptions of the defect each time you visit the dealer.
  • Ask the service advisor to include your complaint and all work performed on the repair order.
  1. Organize all purchase, lease, and warranty papers, plus every repair order and invoice.
  2. Return to an authorized dealer and give them repeated chances to fix the same issue.
  3. Send a dated, written notice to the manufacturer requesting repurchase or replacement under California’s Lemon Law.
  4. Check if your automaker has a California state-certified arbitration program and file there if you prefer a faster resolution.
  5. If unresolved, consult a California lemon law attorney and consider filing in court under the Song-Beverly Act or Magnuson-Moss.
  6. Keep making payments and maintaining insurance until your claim is finalized.

Common Mistakes to Avoid

Save time and protect your claim

Small errors can sink a strong case. Stay organized and insist on complete paperwork.

When in doubt, put it in writing and keep copies.

  • Leaving the dealer without a printed repair order every visit.
  • Letting the shop write “no problem found” when the issue persists—request a test drive with a technician.
  • Failing to note dates, mileage, and exact symptoms for each repair.
  • Missing the 18 months/18,000 miles presumption window when it applies.
  • Signing broad releases or trade-in papers that waive rights without legal advice.
  • Stopping payments or canceling insurance while your claim is pending.

What to Prepare Before Requesting Help

Checklist to speed up your case

Having the right documents ready can lead to faster approvals and stronger outcomes.

Create both digital and paper folders.

  • Purchase or lease agreement, financing paperwork, and title or registration.
  • Written warranties, service contracts, and any extended coverage.
  • All repair orders and invoices, showing dates, mileage, and complaint descriptions.
  • Photos or videos of the defect, dashboard warnings, and tow or rental receipts.
  • Recall and Technical Service Bulletin printouts, if any.
  • Your written notice to the manufacturer and all emails, texts, and call logs.
  • A simple timeline listing each repair attempt and days out of service.
