When a vehicle has a chronic safety defect under warranty—think brakes that fade, airbags that fail to deploy, power steering that cuts out, or engines that stall without warning—it can feel frightening and frustrating. California’s Lemon Law, part of the Song-Beverly Consumer Warranty Act, provides powerful protections for consumers facing these kinds of recurring, safety-related problems. At ZapLemon, our California lemon law firm helps drivers understand their options so they can decide what to do next.
We’ve written this guide to explain how chronic safety defects are treated under California law, what “under warranty” really means, and how a lemon law claim is typically evaluated. It’s educational in nature and designed to help you recognize when it may be time to speak with a lawyer about your situation.
If you’re dealing with repeated safety issues in a car, truck, SUV, motorcycle, or EV that’s still under the manufacturer’s warranty, the information below can help you prepare—especially around documentation, communication with the dealer, and understanding timelines.
Chronic Safety Defects Under Warranty in California
A chronic safety defect is a recurring problem that affects your vehicle’s safe operation or significantly increases the risk of injury—issues like brake failure, steering loss, airbag malfunctions, fuel leaks, electrical shorts leading to smoke or fire, unintended acceleration, sudden stalling, or defective seatbelts. When these defects happen more than once and aren’t fixed after repeated trips to the dealership, they may meet the “substantial impairment” standard under California’s Lemon Law. The key is that the defect must arise during the manufacturer’s warranty period and the dealer must have had a reasonable number of chances to repair it.
California’s Lemon Law includes a “presumption” period that commonly references repairs during the first 18 months or 18,000 miles, whichever comes first. While every case is different, the law generally presumes a vehicle is a lemon if certain thresholds are met—for example, multiple repair attempts for the same issue, two or more attempts for a defect likely to cause serious injury or death, or the vehicle being out of service for repairs for 30 or more cumulative days. These rules are not the only way to prove a lemon, and they don’t guarantee outcomes, but they can be helpful guideposts for consumers.
“Under warranty” doesn’t only mean brand-new vehicles. Many certified pre-owned cars and used vehicles still carry a manufacturer’s warranty. What typically matters is whether the defect appeared and repairs were sought while the manufacturer’s warranty was active, and whether the authorized dealer had the chance to fix it. If you’re unsure about your coverage, check your warranty booklet, call the manufacturer’s customer care line, and keep a folder with all repair orders, invoices, and correspondence. Clear records make it easier to show a pattern of chronic safety issues.
How Our California Lemon Law Firm Reviews Claims
At ZapLemon, we start with a straightforward intake to understand your situation: what the safety defect is, when it began, and how many times you’ve gone back for repairs. We review your purchase or lease agreement, warranty booklet, and—most importantly—your repair orders. Those repair records tell the story: dates in the shop, mileage at each visit, the dealer’s notes, diagnostic codes, and whether parts were replaced or software updates were performed.
Next, we assess whether the facts suggest a chronic safety defect under California’s Lemon Law. We look at whether the defect occurred under the manufacturer’s warranty, whether the dealer had a reasonable number of repair attempts, whether the vehicle was out of service for 30 or more cumulative days, and whether the issue poses a genuine safety risk. We also consider special situations like intermittent problems, “no trouble found” notes, or repeated software updates that don’t solve the root cause—common scenarios with modern vehicles and EVs.
If the claim appears viable, typical next steps may include notifying the manufacturer, gathering any missing records, and discussing routes such as informal dispute resolution programs, negotiations, or filing a lawsuit when appropriate. Possible outcomes under the law can include a repurchase (commonly called a “buyback”), a replacement vehicle, or a cash-and-keep settlement—each with pros and cons. Because every case turns on its own facts, we can’t promise a result, but we can explain the process, timelines, and documentation that can help position your claim.
Practical next steps for consumers include: keep every repair order and invoice; describe symptoms clearly and consistently; note dates, mileage, and safety concerns; take photos or videos when possible; and verify that repairs are performed by an authorized dealer while the warranty is active. If a serious safety issue persists, avoid driving the vehicle until a professional advises it’s safe.
