California Lemon Law Coverage and How to File

California’s Lemon Law exists to protect people who buy or lease vehicles that spend more time in the shop than on the road. If your car, SUV, truck, or van keeps having the same covered problem and the manufacturer can’t fix it after multiple tries, you may have options under the Song-Beverly Consumer Warranty Act—often called the California Lemon Law. This guide from ZapLemon explains what the law generally covers and excludes, and outlines practical steps for starting a claim.

What California’s Lemon Law Covers and Excludes

California’s Lemon Law typically applies to new and used vehicles purchased or leased in California that come with a manufacturer’s warranty. That includes many dealer‑sold used cars (such as certified pre‑owned vehicles), demonstrators, and lease returns—so long as they still have an active manufacturer warranty. The law generally requires a “substantial” defect that is covered by the warranty and that impairs the vehicle’s use, value, or safety. If the manufacturer or its authorized dealer can’t fix that defect after a reasonable number of repair attempts, legal remedies may be available.

There are helpful guideposts for what counts as a “reasonable number” of repairs. California has a legal presumption that can make a claim easier to prove if, within the first 18 months or 18,000 miles (whichever comes first): the dealer tried to repair the same issue at least four times, or at least twice for a defect likely to cause serious injury or death, or the vehicle was out of service for repairs for a total of 30 or more days. Even if your situation falls outside those numbers or timeframes, you may still have a viable claim—the presumption is a shortcut, not the only path.

The law does not cover everything. Problems caused by abuse, neglect, collisions, or unauthorized modifications are generally excluded, as are issues that aren’t covered by the warranty or that don’t materially affect use, value, or safety. Private‑party sales of “as‑is” vehicles usually don’t qualify unless a manufacturer warranty still applies. Certain vehicles are treated differently: small business vehicles can be covered if they weigh under 10,000 pounds GVW and the business has five or fewer vehicles registered in California; motorhomes may be covered for the drivetrain/chassis but not the living quarters; motorcycles have protections but under different rules. Always check your warranty booklet and repair orders to see what applies to your specific vehicle.

Steps to File a California Lemon Law Claim

Start by organizing your paperwork. Gather your purchase or lease agreement, warranty booklet, and every repair order and invoice—each should list the customer complaint, the technician’s findings, the work performed, the dates, and the mileage in and out. Make a simple timeline noting each repair visit and the days your vehicle was in the shop. This recordkeeping is one of the most helpful things you can do, and it costs nothing.

Next, continue to bring the vehicle to an authorized dealership for warranty repairs and clearly describe the problem each time. Avoid “no problem found” outcomes by demonstrating the issue if possible and asking the service advisor to accurately document your complaint. If the issue persists, notify the manufacturer in writing (email or certified mail) and keep copies. Some manufacturers offer California‑certified arbitration programs; these can be faster and free, though you are not required to use them before speaking with an attorney.

When you’re ready to explore your options, consult with a California lemon law attorney. A lawyer can review your repair history, warranty status, and timelines, including the four‑year statute of limitations that generally runs from when you knew or should have known the warranty was breached. While outcomes vary and no result is guaranteed, an attorney can explain potential remedies under the law, such as a repurchase (often called a “buyback”), a replacement vehicle, or payment for incidental expenses where allowed.
