If your car has been in the shop over and over for the same issue, you’re likely wondering whether California’s lemon law can help. At ZapLemon, we hear the same questions every week: What counts as a “lemon,” how many repair attempts are enough, and what should I be documenting? Below, our lemon car lawyers outline California basics and practical steps you can take right now to strengthen a potential claim—shared in plain language and for informational purposes only.
California Lemon Law Basics: What You Must Know
California’s lemon law—part of the Song-Beverly Consumer Warranty Act—generally protects buyers and lessees of new and certain used vehicles that are sold or leased in California with a manufacturer’s warranty. In everyday terms, if your car has a defect covered by the manufacturer’s warranty and the automaker or its authorized dealer can’t fix it after a reasonable number of attempts, you may be entitled to a refund or a replacement. This can include issues like engine stalling, transmission slipping, power steering loss, electrical failures, or repeated check-engine lights that substantially impair the vehicle’s use, value, or safety.
What is a “reasonable number of repair attempts”? California uses a helpful guideline called the lemon law “presumption.” If, within the first 18 months or 18,000 miles (whichever comes first), either: the dealer tried twice to fix a defect that could cause serious injury or death; or tried four or more times to fix the same problem; or the vehicle was out of service for 30 or more cumulative days for warranty repairs, the law presumes the vehicle is a lemon. This is not a hard-and-fast requirement—claims outside these numbers can still be valid—but the presumption provides a useful measuring stick.
If the law applies, typical remedies can include a repurchase (refund of what you paid, with certain lawful deductions such as a mileage offset) or a replacement vehicle. Incidental expenses like towing or rental cars related to the defect may also be recoverable under the statute. Timelines matter: most lemon claims must be brought within a set period, often calculated from when the warranty breach became apparent. Warranty coverage, proper maintenance, and avoiding unauthorized modifications can all affect your rights. Because every situation is fact-specific, a consultation is important to understand your options.
Lawyers’ Tips to Document Defects and Repairs
Start a simple “defect diary.” Each time the issue appears, note the date, mileage, driving conditions, warning lights, sounds, smells, and how the defect affected use or safety (for example, “engine stalled while merging,” or “brakes vibrated at highway speed”). Take photos or short videos of dash messages, leaks, smoke, or infotainment glitches. Save towing receipts and rental or rideshare expenses when the car is down. Consistent, real-world details make patterns easier to prove.
Make sure every repair attempt gets a written repair order when you drop the car off and a final invoice when you pick it up. Use your own words to describe the complaint, and confirm that the service advisor writes it down clearly (“transmission shudders between 2nd and 3rd gear at 25–35 mph,” not just “customer states noise”). Each invoice should show your concern, the diagnosis, tests performed, parts replaced or software updates, dates in and out, and mileage in and out. If the dealer can’t duplicate the problem, ask them to document the symptoms you reported and the circumstances when it happens, and keep that invoice—“no trouble found” still counts as an attempt.
Keep your paperwork organized: purchase or lease contract, warranty booklet, registration, and all repair records. If defects persist, notify the manufacturer in writing (email or certified mail) and keep a copy of your letter and any responses. Avoid clearing codes or disconnecting the battery before service, which can erase useful data. If you receive a loaner, save those records too—they help show time out of service. When you’re ready to have your situation reviewed, a lemon law attorney can assess whether your documentation lines up with California’s rules and discuss next steps.
