If your car keeps going back to the shop for the same problems, you’re not alone—and California’s Lemon Law may offer options. Under the Song-Beverly Consumer Warranty Act, certain recurring defects in new and used vehicles sold or leased in California may qualify for remedies when manufacturers can’t fix them within a reasonable number of attempts. Below, ZapLemon explains the types of defects that commonly qualify and what to watch for, in plain language.
Common Defects That Qualify Under CA Lemon Law
California’s Lemon Law generally focuses on defects that substantially impair a vehicle’s use, value, or safety while it’s under the manufacturer’s warranty. That includes new vehicles and many used or certified pre-owned cars that still have warranty coverage. If a defect keeps coming back after reasonable repair attempts, or your car sits in the shop for extended days, you may be looking at a potential lemon—depending on your specific facts and documentation.
Common qualifying issues include safety-related defects like brake failures or steering problems, drivability issues such as stalling or hesitation, and electrical faults that affect core functions. Recurring check-engine lights, hard starts or no-starts, overheating, transmission slipping, and faulty airbags or seatbelt sensors are examples that can substantially impact use, value, or safety. Persistent water leaks, mold, or severe wind noise can also count when they significantly reduce the vehicle’s value or make it unusable.
California law has a “presumption” that can help consumers in certain cases: if the problem occurs within the first 18 months or 18,000 miles, and the manufacturer or its authorized dealer has had a reasonable number of attempts to fix it (for example, two or more attempts for a defect that could cause serious injury or death, four or more attempts for the same issue, or 30+ total days out of service), the vehicle may be presumed a lemon. This is not the only path to a claim, and every case turns on its facts. Keep detailed repair orders, dates, mileage, and descriptions of symptoms. If a dealer says “no problem found,” ask them to write your description of the issue on the repair order anyway.
Defects Often Covered: Engine, Brakes, Transmission
Engine problems are among the most frequent issues we hear about. Symptoms might include rough idling, misfires, power loss, excessive oil consumption, overheating, or recurring check-engine lights. These can stem from faulty sensors, fuel system defects, timing component failures, or internal engine damage. If your vehicle has been in multiple times for the same engine issue and it still isn’t resolved, keep each repair order and note whether the dealer performed software updates, technical service bulletin (TSB) procedures, or replaced parts.
Brake defects directly affect safety and often escalate the urgency of a claim. Watch for soft or sinking brake pedals, grinding or pulsation even after repairs, longer stopping distances, ABS or brake system warning lights, or repeated brake booster/ABS module failures. If the dealer says the condition is “normal,” yet the symptoms persist, request a road test with a technician, describe when and how the issue occurs (e.g., “after freeway driving, at low speeds”), and ensure that detail is documented. Save any towing receipts or incident notes if you experienced near-miss situations.
Transmission issues can make a vehicle unpredictable or unsafe to drive. Common signs include slipping between gears, hard or delayed shifts, surging, shuddering, sudden loss of power, or transmission-related warning lights. CVTs and dual-clutch transmissions are frequent sources of complaints, often involving software updates followed by repeat concerns. Document each visit, including any reprogramming, fluid changes, or component replacements. If the vehicle has been out of service for many days across multiple visits, add up those days—cumulative time in the shop matters under California law.
