Lemon Law for Faulty Anti-Lock Brake Systems

Anti-lock brake systems (ABS) are designed to help you stop safely and stay in control during emergency braking. When the ABS malfunctions, drivers may experience longer stopping distances, skidding, or dashboard warnings—all of which can be alarming and dangerous. If repeated repair attempts don’t fix the problem, California’s lemon law may offer remedies. Below, ZapLemon explains how the law applies to faulty ABS and what practical steps you can take to protect your rights.

California Lemon Law for Faulty Anti-Lock Brakes

California’s Song-Beverly Consumer Warranty Act—commonly called the California Lemon Law—protects consumers when a vehicle has a defect that substantially impairs its use, value, or safety and the manufacturer can’t fix it within a reasonable number of attempts. ABS issues are often safety-related because they affect stopping performance and steering control under hard braking. If your ABS warning light keeps coming back, or if the system repeatedly fails despite repairs under the manufacturer’s warranty, the problem may qualify as a “nonconformity” under the law.

The law covers new vehicles sold or leased in California with a manufacturer’s warranty, and it can also cover certain used or certified pre-owned vehicles that are still under the original manufacturer’s warranty. California’s “Tanner Consumer Protection Act” presumption can help in some cases: if the defect appears within the first 18 months or 18,000 miles (whichever comes first) and the vehicle has had a reasonable number of repair attempts, it’s presumed to be a lemon. Generally, that presumption can be met if there have been two or more repair attempts for a defect that could cause serious injury or death (brake-related defects often fall in this category), four or more attempts for other defects, or more than 30 total days out of service for repairs. Specific notice requirements may apply, and the presumption is not the only way to prove a lemon.

If your vehicle qualifies, potential remedies under the law can include a repurchase (buyback), a replacement vehicle, or a negotiated cash settlement—though the right outcome depends on the facts of your situation and the applicable warranty. To support any claim, keep detailed records: repair orders, invoices, dates out of service, and communications with the dealer or manufacturer. Because the rules can be technical and deadlines may apply, consider speaking with a California lemon law professional. The team at ZapLemon can review your documentation and help you understand your options.

Signs of ABS Defects and Steps to Protect Your Rights

Common signs of ABS trouble include an illuminated ABS or brake warning light, the traction control or stability control light coming on, or unusual brake behavior—such as the pedal vibrating, going soft or hard, or feeling like it “falls” during stops. You might notice grinding or buzzing from the ABS pump, wheel-speed sensor faults that come and go, or the brakes locking up on slippery roads when they shouldn’t. Sometimes the ABS works intermittently, making it difficult to diagnose without careful testing.

If you suspect an ABS defect, prioritize safety. Avoid driving the vehicle if braking feels unsafe and consider using a tow to the dealership. Ask an authorized dealer to diagnose and repair the system under the manufacturer’s warranty, since warranty repairs and dealer work orders are important evidence. Check the National Highway Traffic Safety Administration (NHTSA) database for recalls, and ask the service advisor whether any technical service bulletins (TSBs) apply to your vehicle—these can signal known issues with ABS modules, hydraulic control units, or wheel-speed sensors.

To protect your rights, document everything. Keep copies of all repair orders that clearly describe your complaint (for example, “ABS light on; longer stopping distance; pedal pulsation”), the technician’s findings, parts replaced, and the dates your vehicle was in the shop. Note any days your vehicle was unavailable, even if the dealer was “waiting for parts.” Avoid resetting warning lights yourself, as that may erase diagnostic trouble codes the dealer needs to see. If problems continue, consider notifying the manufacturer in writing following the instructions in your warranty booklet and keep proof of delivery. Time limits can apply to warranty and lemon law claims; for personalized guidance, consult with a qualified California lemon law attorney.
