Used Car Lemon Law

If your used car keeps going back to the shop for the same problem, you may be wondering whether California’s lemon law can help. The answer changed in 2024, and it now depends mostly on the warranty that came with your car. Faler Law Group helps California drivers understand their options when a used vehicle turns out to be defective.

Does California’s Lemon Law Cover Used Cars?

Sometimes. California’s lemon law, part of the Song-Beverly Consumer Warranty Act, gives buyers of “new motor vehicles” the right to a buyback or replacement when the manufacturer can’t fix a warranty defect after a reasonable number of attempts. Whether a used car counts as a “new motor vehicle” for this purpose depends on how and with what warranty it was sold.

Even when the buyback remedy doesn’t apply, a used car buyer may still have warranty rights against the dealer or manufacturer, and fraud claims if the car was misrepresented.

What Changed: Rodriguez v. FCA US (2024)

On October 31, 2024, the California Supreme Court decided Rodriguez v. FCA US. The buyers in that case purchased a two-year-old truck from a used car dealer while some of the original factory warranty was still in effect. The court held that a used car sold with only the balance of the original warranty is not a “new motor vehicle” under the lemon law, unless a new manufacturer’s warranty was issued with the sale.

Before Rodriguez, many used car buyers brought lemon law claims based on the remaining factory warranty. After the decision, most of those buyers can no longer get the lemon law’s buyback or replacement remedy from the manufacturer.

When a Used Car May Still Be Covered

• A new warranty was issued with the sale. The lemon law’s definition still covers dealer demonstrators, dealer-owned vehicles and other vehicles sold with a manufacturer’s new car warranty issued with the sale.
• Certified pre-owned vehicles. The court didn’t decide whether certified pre-owned warranties qualify. It depends on the warranty you received, so keep the certification and warranty paperwork.
• The dealer gave its own written warranty. Under Civil Code section 1795.5, a dealer that gives an express warranty on a used vehicle generally takes on the same warranty obligations a manufacturer has under the Song-Beverly Act.
• The factory warranty still has to be honored. The manufacturer must still make covered repairs under any remaining warranty, and other state and federal warranty claims may apply if it doesn’t.
• The dealer misrepresented the car. If you were lied to about the vehicle’s history, condition or mileage, auto fraud claims may apply no matter what warranty came with it.

“As Is” Sales and Implied Warranties

Dealers must post a Buyers Guide window sticker on the used cars they offer for sale, showing whether the car comes with a warranty or is sold “as is.” An “as is” sale generally means the dealer isn’t promising the car is free of defects.

There are important limits. When a dealer gives a written warranty on a used car, California law adds an implied warranty that the car is fit for ordinary use, lasting as long as the written warranty but no less than 30 days and no more than three months. And under federal law (15 U.S.C. section 2308), a dealer that sells you a service contract at the time of sale or within 90 days afterward generally can’t disclaim implied warranties.

The 3-Day Right to Cancel

California’s CARS Act gives buyers a new way out of some used car purchases. Since October 1, 2026, a used vehicle priced at $50,000 or less can generally be returned within three days after signing, as long as it hasn’t been driven more than 400 miles. A restocking fee applies, and the dealer must give you a written notice explaining how to cancel.

What You May Be Able to Recover

It depends on which claims apply to your vehicle. Depending on the facts, you may be able to:

• A buyback or replacement under the lemon law, if a new manufacturer’s warranty was issued with the sale.
• Repairs or compensation under the dealer’s or manufacturer’s warranty, including your out-of-pocket costs from a breach.
• Undo the sale or recover your losses if the dealer misrepresented the vehicle.

Every case is different, and the outcome depends on the facts and the paperwork.

What to Do If Your Used Car Keeps Breaking Down

1. Find your warranty paperwork. The Buyers Guide, any dealer or certified pre-owned warranty, and any service contract you bought.
2. Take the car to an authorized repair facility under the warranty, and describe the problem the same way each time.
3. Keep every repair order. Make sure each one lists your complaint, the dates and the mileage in and out.
4. Keep your purchase contract and any ads or messages from the dealer about the car.
5. Don’t sign a release or trade the car in before talking to an attorney.
6. Act quickly. Warranties expire and time limits apply.

Used Car Lemon Law FAQ

Does California’s lemon law cover used cars?

Sometimes. Since the 2024 Rodriguez v. FCA US decision, a used car isn’t covered by the lemon law’s buyback and replacement remedy just because some of the original factory warranty is left. A used car may still qualify if a new manufacturer’s warranty was issued with the sale, and other warranty or fraud claims may apply.

Is a certified pre-owned car covered by the lemon law?

It depends on the warranty. The Rodriguez decision didn’t address certified pre-owned vehicles directly. If a new manufacturer’s warranty was issued with the sale, the vehicle may qualify. Have your certified pre-owned paperwork reviewed.

My used car still has factory warranty left. What can I do?

The manufacturer still has to honor that warranty and make covered repairs. The remaining warranty alone usually doesn’t make the car eligible for a lemon law buyback anymore, but other warranty claims may apply if the problem isn’t fixed.

What if I bought my used car “as is”?

An “as is” sale generally means the dealer isn’t promising the car is free of defects. But a dealer that gives you its own written warranty, or sells you a service contract within 90 days of the sale, generally can’t disclaim implied warranties. And “as is” never allows a dealer to lie about the car.

Can I return a used car in California?

In some cases. Since October 1, 2026, a used vehicle priced at $50,000 or less can generally be returned within three days after signing, as long as it hasn’t been driven more than 400 miles, subject to a restocking fee. If a dealer misrepresented the car, you may have other ways to undo the sale.
