Common Questions About California Lemon Law

If a new or used vehicle in California keeps going back to the shop for the same problems, you might be wondering whether it qualifies as a “lemon.” California’s lemon law can offer strong protections, but the rules can be confusing when you’re dealing with warranty terms, repair attempts, and time limits. This article answers common questions in plain language so you can better understand what to look for and what to document.

What Qualifies a Car as a Lemon in California?

In California, the lemon law (part of the Song-Beverly Consumer Warranty Act) generally applies when a vehicle has a substantial defect that affects its use, value, or safety, the problem arises within the manufacturer’s warranty period, and the manufacturer or its authorized dealer can’t fix it after a reasonable number of attempts. “Substantial” doesn’t mean perfect; it means the issue meaningfully interferes with driving, safety, or ownership. This can include repeated stalling, transmission failures, serious braking problems, steering defects, or electrical issues that cause the vehicle to shut down or lose key functions.

Coverage is broader than many people think. The law can apply to new and used vehicles sold or leased in California that are covered by a manufacturer’s written warranty, including many certified pre-owned vehicles still under warranty. Certain small business vehicles may also qualify (for example, under 10,000 lbs. GVWR and owned by a business with a small fleet). Generally, the problem can’t be the result of abuse, neglect, or unauthorized modifications, and repair work should be done by an authorized dealership or facility.

Real-world examples can help. If your SUV’s transmission slips, the dealership attempts multiple repairs, and the problem keeps returning, that could be a qualifying defect. Repeated check-engine lights that lead to rough running or stalling, persistent brake shudder or ABS faults, or a power steering failure that wasn’t fixed after several tries are other common scenarios. Minor annoyances like a rattling trim piece may not qualify on their own. The key is consistent, well-documented symptoms and repair attempts within the warranty period.

How Many Repairs or Days Out Qualify as a Lemon?

California has a legal “presumption” that helps consumers within the first 18 months or 18,000 miles (whichever comes first). During that window, your vehicle is presumed to be a lemon if: (1) the same serious safety defect—one that is likely to cause death or serious bodily injury—has been subject to at least 2 repair attempts and still isn’t fixed; or (2) the same non-safety defect has been subject to at least 4 repair attempts; or (3) the vehicle has been out of service for repair for a total of 30 or more cumulative days. The manufacturer must have an opportunity to repair, and in some cases notice requirements in the warranty or owner’s manual may apply.

Importantly, not meeting the presumption doesn’t end your rights. You may still have a valid claim outside the 18-month/18,000-mile window or with fewer than the listed attempts if the problems are significant and the manufacturer had a reasonable chance to fix them. “Reasonable” can depend on the severity of the defect, how frequently it occurs, and its impact on use, value, or safety. Days out of service are counted cumulatively and can include multiple visits for the same nonconformity; extended parts delays or wait times can matter too.

Practical tips make a difference. Keep all repair orders and note dates, mileage, symptoms, and what the repair facility did. Make sure your complaint is written on the work order in your own words. If your warranty requires written notice to the manufacturer, send it and keep proof. Don’t delay addressing warning lights or recall notices. If the car is undriveable, note any towing and rental-car details. These records help show the number of repair attempts and days out, which are central to lemon law evaluations.
