California Lemon Law for Traction Control Failures

When the traction control light keeps flashing, the car cuts power during normal driving, or the system disables itself in wet or icy conditions, it’s more than a nuisance—it can affect safety and confidence behind the wheel. In California, the Song-Beverly Consumer Warranty Act—often called the California Lemon Law—may offer protections when a traction control defect persists under warranty despite repeated repair attempts. This article explains the basics and outlines practical steps you can take, all in plain language.

California Lemon Law Basics for Traction Control Failures

Traction control (often labeled TCS) works with your vehicle’s anti-lock braking system (ABS) and electronic stability control (ESC) to prevent wheel spin and help maintain grip. Common signs of a traction control problem include a warning light that stays on, sudden power reduction, grinding or pulsating sensations, or the system deactivating even in normal conditions. These issues can stem from faulty wheel-speed sensors, wiring problems, a bad steering-angle or yaw sensor, software glitches, or a defective ABS/ESC module.

Under the California Lemon Law, consumers may have remedies when a covered defect substantially impairs the vehicle’s use, value, or safety and the manufacturer or its authorized dealer can’t fix it after a reasonable number of attempts. The law typically applies to new vehicles and many used vehicles that are still under the manufacturer’s warranty. As a general guide—not legal advice—California has a “lemon law presumption” that may apply during the first 18 months or 18,000 miles if certain thresholds are met (for example, multiple repair attempts for the same problem or significant days out of service), but claims can also exist outside that window depending on the facts.

If traction control failures persist, potential outcomes under the law can include a repurchase (buyback), a replacement vehicle, or a negotiated cash-and-keep settlement. Any remedy is fact-specific and may involve deductions such as a mileage offset. Because every situation is unique, a consultation is the best way to understand how the law may apply to your particular vehicle, warranty, and repair history.

Steps to Take if Traction Control Problems Persist

Document everything from day one. Note when the warning light appears, road conditions, speed, and any loss of power or stability. Each time you visit the dealer, request a detailed repair order that lists your complaint, the technician’s findings, diagnostic trouble codes (DTCs), software updates, and parts replaced. Saving photos or short videos of the symptoms can be helpful, and checking for recalls or Technical Service Bulletins (TSBs) through NHTSA’s website can provide context you can share with the service advisor.

Work through the authorized dealer so repairs are tied to the manufacturer’s warranty. Explain the symptoms clearly and consistently, and ask that “unable to duplicate” or intermittent behavior be noted accurately on the repair order. If the issue returns, go back promptly and keep your paperwork organized in date order. If repairs drag on, ask the dealer to open a case with the manufacturer and record the case number; keep notes of dates, names, and what was discussed. Track total days your car is out of service, as that can matter under California law.

When repeated repair attempts aren’t solving the traction control defect, consider speaking with a California lemon law professional. Time limits may apply, and getting tailored guidance early can help you understand your options without making promises about outcomes. For safety-related concerns, follow manufacturer guidance in your owner’s manual and prioritize your safety while you explore next steps with a qualified team like ZapLemon.
