Common California Lemon Law Filing Mistakes

Waiting too long to take action is one of the biggest pitfalls. California’s lemon law generally applies to vehicles with defects covered by the manufacturer’s warranty, and there are deadlines that may apply to your claim. If you delay reporting issues, skip service visits, or wait months to document problems, it can be harder to show a pattern of defects or that the problem arose during the warranty period.

Another frequent mistake is poor documentation. Service advisors don’t always write your complaint the way you describe it, and “could not duplicate” notes can appear even when the problem is real. If you don’t keep every repair order, note dates and mileage, and save photos or videos of the defect (for example, a dashboard warning, stalling, or a transmission shudder), you might not have the clear paper trail needed to demonstrate repeated repair attempts or long periods out of service.

A third mistake is only talking to the dealership and never notifying the manufacturer. Many warranties require you to give the manufacturer an opportunity to repair, and in some cases a written notice can be important. Consumers also sometimes sign paperwork they don’t fully understand—like broad releases, mandatory arbitration agreements, or “goodwill” settlements that can limit options later. Before you sign anything that could affect your rights, take time to understand what it means.

How to Spot and Avoid Costly Lemon Claim Pitfalls

Start by recognizing patterns that may qualify under California’s lemon law (often called the Song-Beverly Consumer Warranty Act). Red flags include recurring defects that affect use, value, or safety—such as engine stalling, brake failure, airbag or ADAS warnings, transmission slipping, electrical shutdowns, steering pull, or water leaks—especially when the dealer has attempted repairs multiple times. Extended time in the shop can also matter; long stretches without your car are worth tracking.

Build a strong record from day one. At each visit, ask the advisor to write your complaint exactly as you reported it (“vehicle stalls at stoplights,” “infotainment reboots while driving,” “hybrid battery warning under load”). Keep copies of all repair orders, tow receipts, rental car invoices, and any emails or texts with the dealer or manufacturer. Use your phone to record videos of the issue, note dates and mileage, and store everything in a dedicated folder. Verify warranty coverage in your booklet, check for recalls or technical service bulletins, and avoid aftermarket modifications that could complicate warranty arguments.

Consider next steps before accepting quick fixes. Manufacturer programs (including informal dispute procedures) can be an option, but they may not fit every situation. California’s lemon law can provide remedies such as repurchase, replacement, or a cash settlement in certain circumstances, but the best approach depends on your facts and timing. Because these decisions can be complex, many consumers choose to consult a California lemon law attorney. ZapLemon can explain your options in a consultation so you can decide what’s right for you—no promises or guarantees are made or implied.
