How California Lemon Law Protects New Car Buyers

Buying a new car should be exciting—not a recurring service appointment. California’s Lemon Law, part of the Song-Beverly Consumer Warranty Act, is designed to protect new car buyers when a vehicle has serious, repeat problems that the manufacturer can’t or won’t fix within a reasonable time. This article explains what typically qualifies as a “lemon” in California and outlines practical steps you can take if your new car keeps breaking down, so you can make informed decisions about what to do next.

What qualifies as a lemon under California law

In California, a new vehicle may qualify as a lemon when it has a defect that’s covered by the manufacturer’s warranty and that substantially impairs the vehicle’s use, value, or safety. Think of issues like brakes that pulsate or fail, engines that stall or overheat, transmissions that jerk or won’t shift, or electrical systems that repeatedly cut out—problems that go beyond mere annoyances. The key is that the defect isn’t fixed after the manufacturer or its authorized dealer has a reasonable number of attempts to repair it.

California has a “lemon law presumption” to help consumers during the first 18 months or 18,000 miles (whichever comes first). During that period, your vehicle is presumed to be a lemon if, for example, the dealer tried to fix the same problem four or more times, or two or more times for a defect that could cause serious injury or death, or if the car was out of service for more than 30 cumulative days for warranty repairs. This presumption is not the only way to prove a lemon case—it simply makes it easier during that early window.

Even outside the 18-month/18,000-mile presumption, you may still have rights if the defect arose and was reported during the warranty period and wasn’t fixed after reasonable attempts. If your car qualifies, potential remedies can include a manufacturer buyback (refund minus a mileage offset for use), a replacement vehicle, or in some situations a cash settlement to keep the car. Every situation is different, and outcomes depend on facts like the nature of the defect, repair history, and warranty terms.

Steps to take if your new car has recurring defects

Start by documenting everything. Each time a problem occurs, note the date, mileage, and symptoms, and take photos or videos when safe to do so. Bring the car to an authorized dealership for diagnosis and repair, describe the issue clearly, and ensure the repair order lists your concern in your own words. Keep copies of all repair orders, invoices (even for “no problem found”), towing receipts, loaner/rental records, and communications with the dealer or manufacturer.

Review your warranty booklet to confirm coverage and follow any instructions for obtaining repairs. If the problem continues, contact the manufacturer’s customer care line to open a case and give them an opportunity to resolve it. Ask for all updates in writing and track how long your vehicle is out of service. Do not stop making loan or lease payments while your case is pending—missed payments can harm your credit and complicate your options.

If repairs aren’t successful after reasonable attempts, consider speaking with a California lemon law attorney about your situation. California law may require the manufacturer to pay reasonable attorney’s fees and costs if you prevail, but a consultation is necessary to evaluate your options. Some manufacturers offer arbitration programs; these can be quicker but are not always the best fit, so it’s wise to learn how they work before deciding. Throughout the process, keep your records organized—strong documentation often makes all the difference.
