If your “new-to-you” car keeps stalling, the transmission shudders on every commute, or your EV’s battery range drops dramatically, you may be wondering whether California’s lemon law can help. The state’s Song-Beverly Consumer Warranty Act protects buyers and lessees when a vehicle under warranty has persistent defects that substantially impair use, value, or safety. Filing a claim, however, can be confusing—so here are eight common mistakes Californians make and how to steer clear of them.
8 Lemon Law Filing Mistakes Californians Make
A frequent misstep is (1) waiting too long to act. Time matters: delays can make it harder to gather records, lose leverage, or run into deadlines tied to warranties and statutes of limitation. Another is (2) failing to document problems and repairs. If you don’t have repair orders that list your complaints, mileage, dates, and the dealer’s findings, you’re relying on memory instead of evidence. A third is (3) using independent shops for warranty repairs. For lemon purposes, manufacturers typically require that you give an authorized dealership the chance to diagnose and fix the defect.
Many people also (4) stop returning when the problem comes back. One visit is rarely enough—lemon claims often hinge on a “reasonable number” of attempts for the same or related issue, or days out of service for repairs. Another common misunderstanding is (5) assuming any annoyance qualifies. Rattles or cosmetic issues may not rise to “substantial impairment,” while safety-related problems—like engine stalling, loss of power, brake failures, steering pull, airbag warnings, or repeated infotainment reboots that affect backup cameras—often do. Then there’s (6) modifying, neglecting, or abusing the vehicle. Performance tunes, lift kits, or skipped maintenance can give the manufacturer an argument that the defect wasn’t their responsibility.
Finally, many owners (7) don’t provide clear written notice to the manufacturer beyond talking to the service advisor. If you never escalate, you may miss internal review processes that lead to buybacks or replacements. And (8) signing quick “trade assists,” extended warranties, or broad releases without understanding the terms can lock you into a less favorable outcome. Lowball offers may not account for taxes, registration, finance charges, or negative equity, and selling or transferring the vehicle mid-claim can complicate your options.
How to Avoid Pitfalls That Jeopardize Your Claim
Start by building a clean record. Keep a defect diary that notes symptoms, dates, weather conditions, dashboard lights, videos or photos, and how the issue affects driving. Save every repair order and make sure the advisor writes your complaint in your own words (for example, “vehicle hesitates shifting 2–3,” “vehicle stalls at stops,” or “range drops 40% after update”). Check your warranty booklet so you know what’s covered and confirm you’re using an authorized dealership for warranty repairs. If the problem returns, schedule follow-up visits promptly and describe that it’s the same recurring issue.
Communicate clearly and in writing. In addition to dealer visits, contact the manufacturer’s customer care line, get a case number, and send a brief written summary (email or certified mail) of the defect history, including dates, mileage, repair orders, and days out of service. Ask for assistance consistent with California’s lemon law process. Be cautious with offers that aren’t transparent—politely decline to sign anything you don’t understand, especially releases. Consider consulting a professional before you agree to a settlement so you know what you’re giving up and what’s included.
Protect your vehicle and your timeline. Avoid aftermarket performance modifications while the defect is unresolved, follow the maintenance schedule, and complete recall or technical service bulletin updates the dealer recommends. Don’t wait—acting earlier helps preserve evidence and options under California law. Gather key documents now: purchase or lease agreement, registration, warranty booklet, and your repair file.
