Overview

California’s Lemon Law can protect buyers of used cars when the vehicle has a warranty and serious defects aren’t fixed after a reasonable number of attempts.

If you qualify, the manufacturer or selling dealer may have to repurchase or replace the vehicle and reimburse certain costs.

Do You Qualify?

  • Written warranty at purchase: The car was sold or leased with a manufacturer’s warranty still in effect (including Certified Pre‑Owned) or a dealer warranty . A service contract alone usually is not enough.
  • Covered defect: The issue is covered by the warranty and not caused by abuse, neglect, or aftermarket modifications.
  • Substantial impairment: The defect substantially impairs use, value, or safety (e.g., engine, transmission, brakes, airbags, electronics).
  • Reasonable repair attempts: The manufacturer/dealer had a fair chance to fix it (often 2+ for serious safety issues, 4+ for others, or 30+ cumulative days out of service).
  • Within the warranty period: Repair attempts occurred while the warranty was active (report the problem before it expires).
  • Personal use (mostly): Primarily for personal/family use. Small businesses may qualify if the vehicle is under 10,000 lbs. GVWR and the business owns five or fewer vehicles.
  • Bought or leased in CA: Generally applies to vehicles purchased or leased in California . Some exceptions exist for active‑duty military.

How CA Law Applies

Used Cars That Typically Qualify

California’s Song‑Beverly Consumer Warranty Act covers new and used vehicles sold with a written warranty. It requires repair within the warranty period and a refund or replacement if repairs fail after reasonable attempts.

Within the first 18 months or 18,000 miles from the vehicle’s original delivery (even for a used buyer), the law presumes a lemon if:

Outside that window, you can still win with proof of repeated, unsuccessful warranty repairs.

  • Still under manufacturer warranty: Even if you’re the second or third owner.
  • Certified Pre‑Owned: Usually includes an extended manufacturer warranty.
  • Dealer warranty: Triggers lemon law duties for the selling dealer during the warranty term.
  • Buy‑Here‑Pay‑Here dealers: Must provide at least a 30‑day/1,000‑mile warranty by law in CA.
  • Private party sales: Covered only if the manufacturer’s warranty is still in effect.
  • 2+ repair attempts for a defect likely to cause serious injury or death, or
  • 4+ attempts for other recurring defects, or
  • 30+ cumulative days in the shop.
  • Manufacturer: When a manufacturer warranty applies.
  • Dealer: When only a dealer warranty applies (the dealer, not the manufacturer, is typically responsible).
  • Repurchase (buyback): Refund of price paid (including tax, title, registration), minus a mileage offset from the first repair attempt for the defect.
  • Replacement: Comparable vehicle plus tax/fees adjustments.
  • Incidental damages: Towing, rental, and other reasonable out‑of‑pocket costs.
  • Civil penalties and fees: Possible penalties for willful violations and recovery of reasonable attorney’s fees.

Step-by-Step: What to Do

  1. Step 1: Confirm warranty status. Use your VIN on the manufacturer’s site or call a dealer. Note in‑service date, remaining coverage, and any CPO/dealer warranty terms.
  2. Step 2: Document everything. Keep purchase/lease contract, warranty booklet, all repair orders, texts/emails with the dealer, and tow/rental receipts.
  3. Step 3: Get authorized warranty repairs. Return to an authorized repair facility. Clearly describe the defect. Ensure each visit produces a dated repair order listing your complaint and mileage.
  4. Step 4: Give a final opportunity. If the problem persists, send a written notice to the manufacturer (and dealer if it’s a dealer warranty) requesting a final repair and a buyback/replacement if it fails.
  5. Step 5: Consider arbitration. Some brands offer free programs. It’s optional in CA; get advice before opting in.
  6. Step 6: Talk to a CA lemon law attorney. Many offer free consultations and fee‑shifting means the manufacturer may pay your legal fees if you win.

Common Mistakes to Avoid

  • Not getting repair orders: No paperwork, no proof. Always leave with a detailed repair invoice.
  • Using non‑authorized shops: Can jeopardize warranty coverage. Use manufacturer‑authorized facilities during the warranty.
  • Waiting until after warranty expires: Report issues and open a repair order before coverage ends.
  • Withholding payments or returning the car: This can harm your credit. Keep paying unless an attorney advises otherwise.
  • Modifying the vehicle: Aftermarket tunes or parts can give the manufacturer a defense.
  • Assuming “as is” ends all rights: Manufacturer warranties still apply if active; dealer obligations may also exist under CA law.

What You Should Do Next

Check your VIN for active manufacturer/CPO coverage, gather your repair records, and schedule service at an authorized shop.

If the defect persists after reasonable attempts, consult a California lemon law attorney to evaluate buyback or replacement options and next steps.
