Lemon Vehicle Complaints: What Counts as a Safety Defect

If your car keeps going back to the shop and you’re worried about whether it’s safe to drive, you’re not alone. Many California drivers wonder when a recurring problem becomes a “safety defect” under the state’s lemon law. This article explains, in plain language, how California defines safety defects and how common issues like brakes, steering, and airbags can fit into a lemon claim. It’s meant to help you spot red flags and get organized—not to provide legal advice for your specific situation.

What California Lemon Law Calls a Safety Defect

Under California’s Song-Beverly Consumer Warranty Act (the “lemon law”), a defect can qualify in two closely related ways: it can substantially impair the vehicle’s use, value, or safety, or it can be a “serious safety defect.” A serious safety defect generally means a problem that is likely to cause death or serious bodily injury if the car is driven. In practical terms, that goes beyond annoyances like a sticky cupholder—it’s about conditions that make the vehicle dangerous to operate.

California also recognizes a “lemon law presumption” during the first 18 months or 18,000 miles (whichever comes first). Under that presumption, the law may assume the manufacturer had a reasonable number of repair opportunities if, for example, a serious safety defect was subject to two or more repair attempts, the same non-safety defect was attempted four or more times, or the vehicle was out of service for 30 or more total days for warranty repairs. You can still have a valid claim outside these time and mileage limits, but the presumption makes the path clearer within them. New and used vehicles can qualify if covered by the manufacturer’s warranty when the repair attempts occurred.

If you suspect a safety defect, act quickly and document everything. Take the car to an authorized dealership, describe the symptoms in detail, and request a repair order every time—even if the shop “cannot duplicate” the problem. Keep photos or videos of the issue, note warning lights and driving conditions, and save all communications with the dealer and manufacturer. Check for recalls or technical service bulletins, verify your warranty coverage, and avoid driving the vehicle if it seems unsafe.

Real-world Examples: Brakes, Steering, Airbags

Braking issues are among the clearest safety concerns. Warning signs include a soft or sinking brake pedal, grinding or pulsation, ABS or brake warning lights, longer stopping distances, or fluid leaks. Failures of components like the master cylinder, brake booster, ABS module, or calipers can create dangerous stopping conditions. If the dealer has tried to fix the same brake problem multiple times or you’ve been without your car for extended periods due to brake repairs, that pattern can support a safety-defect complaint.

Steering defects can make a vehicle unpredictably hard to control. Common symptoms include intermittent or total loss of power steering assist, EPS or steering warning lights, difficulty turning the wheel, “notchy” or wandering steering, strong pulls to one side, or clunking from the steering rack or tie rods. Some issues appear only at certain speeds or temperatures, or after longer drives. Document when the problem occurs, the speed, road surface, temperature, and whether the steering wheel re-centers properly. Persistent steering problems—especially those that affect lane keeping or emergency maneuvers—often fit squarely within the concept of a safety defect.

Airbag and seatbelt systems (SRS) are critical safety equipment. Red flags include an illuminated airbag/SRS light, airbag deployment without a crash, failure to deploy in a crash, or faults involving sensors, clocksprings, seat weight sensors, or seatbelt pretensioners. Because SRS relies on crash sensors and control modules, some problems won’t show obvious symptoms until scanned; ask the dealer for pre- and post-repair diagnostic reports and don’t clear codes yourself. Airbag defects can trigger the presumption after two repair attempts within the 18 months/18,000 miles window because of the risk of serious injury.
