Seatbelts, airbags, and the sensors that control them aren’t just features—they’re life-saving systems. When these safety restraints don’t work correctly, the problem can be scary and disruptive, and it may also raise important rights under California’s Lemon Law. This article explains how the law applies to safety restraint defects and what steps you can take to protect yourself and your claim.
California Lemon Law: Safety Restraint Defects 101
California’s Lemon Law, part of the Song-Beverly Consumer Warranty Act, can apply when a new or used vehicle (sold with the manufacturer’s new-vehicle warranty or a certified pre-owned warranty) has defects that substantially impair its use, value, or safety, and the manufacturer can’t fix them after a reasonable number of attempts. Safety restraint systems include more than just the seatbelt and airbag. They also include the pretensioners that tighten a belt in a crash, the seatbelt latch and retractor, the airbag control module (SRS/SDM), clockspring in the steering wheel, occupancy and weight sensors that control passenger airbag activation, seat position sensors, crash sensors, and even LATCH/child-seat anchor integrity.
Because restraint defects go to the heart of safety, they can weigh heavily in Lemon Law assessments. California’s Lemon Law “presumption” (often called the Tanner presumption) may apply during the first 18 months or 18,000 miles, whichever comes first. Under that presumption, a vehicle may qualify if: (1) two or more repair attempts were made for a defect likely to cause death or serious bodily injury if the vehicle is driven; (2) four or more attempts were made for any other defect; or (3) the vehicle was out of service for repairs for a total of 30 or more days. Airbag or seatbelt failures and persistent SRS warning lights can fall into the first category because they may indicate a risk of serious injury.
Real-world examples include an airbag light that keeps returning after “clearing codes,” seatbelt buckles that don’t latch, retractors that won’t hold during braking, pretensioner fault codes after a minor collision, airbags that fail to deploy or deploy unexpectedly, a passenger occupancy sensor misreading an adult as a child (disabling the airbag), ongoing clockspring faults affecting the driver’s airbag, or LATCH anchors that are loose or misaligned. Parts delays for safety restraint components are also common; if your vehicle sits at the dealership for weeks awaiting a replacement SRS module or harness, those days can count toward total days out of service.
Steps to Take and When to Contact ZapLemon for Help
If a safety restraint light comes on or you notice buckles, belts, or airbags acting strangely, schedule a dealer visit right away. Describe symptoms clearly: when the light appears, whether it’s intermittent, any noises or warning chimes, and what passengers or cargo were present. Ask the advisor to note your safety concerns on the repair order, and request that the dealer road-test and fully diagnose the system. Avoid DIY fixes or clearing codes yourself; it can erase data that helps document the problem.
Document everything. Keep copies of all repair orders, invoices, diagnostic reports, and warranty repair lines. Write down dates, mileage in and out, and the number of days your vehicle is at the shop. Take photos or short videos of warning lights or messages when safe to do so. If the dealer mentions a service bulletin (TSB) or recall, ask for the bulletin or campaign number. Save emails or texts with the service department or manufacturer. Consistent records help show the pattern and persistence of a defect.
Reach out to ZapLemon if you’ve had repeated repair attempts without a lasting fix, if your vehicle has been at the dealership for extended periods awaiting parts, or if the manufacturer has denied coverage while the issue persists. Timing matters—especially within the first 18 months/18,000 miles or while your warranty is active—so early guidance can be helpful. ZapLemon can review your repair history, discuss potential remedies available under California law (such as repurchase, replacement, or a negotiated cash payment), and explain next steps so you can make an informed decision after a consultation.
Safety restraint problems are among the most serious vehicle defects because they affect your protection in a crash.
