California Lemon Law Coverage for Traction Control Issues

If your traction control light keeps flashing, your vehicle shudders when turning, or you lose stability in wet conditions, you’re not imagining it—traction control and stability systems are critical safety features. In California, repeated problems with these systems can fall under the state’s lemon law if they occur under warranty and the manufacturer cannot fix them after reasonable attempts. Below, ZapLemon explains how California’s lemon law treats traction control defects and how to document your repair history to protect your rights.

Does CA Lemon Law Cover Traction Control Defects?

California’s lemon law (the Song-Beverly Consumer Warranty Act) generally applies when a vehicle has a defect covered by the manufacturer’s warranty that substantially impairs the car’s use, value, or safety, and the manufacturer can’t repair it within a reasonable number of attempts. Traction control and electronic stability control are safety-related systems that work alongside ABS, wheel-speed sensors, yaw sensors, and the powertrain. When these systems malfunction—think persistent “Traction Control,” “ESC,” or “Stability Control” warnings, unexpected power cut, or fishtailing in normal driving—they may meet the “safety” impairment threshold.

A “reasonable number of repair attempts” depends on the facts. California’s lemon law presumption (which applies within the first 18 months or 18,000 miles, whichever comes first) is triggered if: there are two or more repair attempts for a defect likely to cause death or serious injury, four or more attempts for the same issue, or 30 or more cumulative days out of service. Even if your car falls outside the presumption window, it may still qualify based on the overall repair history. Example: you’ve returned three times for a traction control warning, the dealer replaced a wheel-speed sensor and a steering angle sensor, but the warning and loss of power persist—this pattern may be enough to explore lemon law remedies.

If your vehicle does qualify, potential remedies can include a repurchase (buyback), a replacement vehicle, or a negotiated cash-and-keep settlement. Any repurchase usually involves a mileage offset for the use you received before the first repair attempt. You may also be entitled to reimbursement for reasonable towing and rental expenses tied to the defect. Every case is different, and manufacturers may point to software updates, recalls, or “normal operation” explanations, which is why reviewing your specific facts and records matters before deciding on next steps.

How to Document Traction Control Repairs in California

Start with clear, consistent repair documentation. Each time you visit the dealer, ask the service advisor to write your complaint in detail: exactly which lights or messages appeared (“Service ESC,” “Stabilitrak,” ABS), the driving conditions (rain, freeway speed, turning left, accelerating from a stop), and the symptoms (wheel slip, engine power reduced, braking pulsing, steering pull). Make sure the repair order lists your mileage and the in/out dates so you can track total days out of service. Before leaving, verify that the final invoice shows what the dealer did (diagnostics performed, codes pulled, parts replaced, software versions, road test results).

Gather supporting evidence between visits. Take photos or short videos of the dashboard warnings and any messages on the instrument cluster or infotainment. Note the time, weather, speed, and road surface when the problem occurs. If you have access to a scan tool, record stored diagnostic trouble codes (for example, wheel-speed sensor or ABS/ESC communication codes), but avoid clearing them before service. Keep copies of recall notices, technical service bulletins provided to you, towing receipts, rental car invoices, and any messages or emails with the dealer or manufacturer.

If the issue persists, escalate politely but firmly. Open a case with the manufacturer’s customer care line and write down your case number. Consider sending a written notice (certified mail) describing the ongoing traction control defect and your repair history, and request that the manufacturer perform a final repair attempt under warranty. Keep using an authorized dealership for repairs, avoid modifications that could complicate diagnostics, and continue documenting every visit.
