Does California's Lemon Law Cover Used or CPO Cars?

Whether California's lemon law covers your vehicle depends on what kind of vehicle it is and how it was sold — and a 2024 California Supreme Court decision significantly changed the answer for one common category. Here's where used, certified pre-owned, demo, and loaner vehicles stand today.

Used Cars With the Remaining Factory Warranty: The 2024 Rodriguez Decision

On October 31, 2024, the California Supreme Court issued its unanimous decision in Rodriguez v. FCA US, LLC (2024) 17 Cal.5th 189. The Court held that a used motor vehicle purchased with only the remaining balance of the manufacturer's original new-car warranty does not qualify as a "new motor vehicle" under the Song-Beverly Act, and therefore is not entitled to the full lemon law remedies.

This decision expressly disapproved the long-standing 1995 precedent from Jensen v. BMW of North America, Inc., which for nearly 30 years had treated used vehicles sold with remaining factory-warranty coverage as qualifying for full Song-Beverly protection. In short, simply buying a used car that still has time left on the original warranty no longer guarantees lemon law coverage on its own.

Certified Pre-Owned (CPO) Vehicles

Certified pre-owned vehicles remain protected under California's lemon law, known as the Song-Beverly Act. Because a CPO vehicle is sold with a manufacturer's warranty, a substantial defect that the manufacturer cannot repair after a reasonable number of attempts can entitle you to a buyback, replacement, or cash settlement — with the manufacturer paying your attorney fees.

Demo and Loaner Vehicles

Demonstrator ("demo") and loaner vehicles are also covered under the Song-Beverly Act, as long as you are the first retail buyer of the car. These vehicles are driven before sale, but a first retail purchaser still receives the law's full protections against substantial, unrepaired defects.

Not Sure Where Your Car Stands?

The rules around used and pre-owned vehicles are more nuanced than they were a year ago, and the specifics of how your vehicle was sold and warrantied matter. A free case review is the quickest way to find out whether your vehicle qualifies under California's lemon law.
