When a modern car’s steering sensor acts up—think steering angle sensors, torque sensors, or the electronics that power electric power steering—drivers can experience anything from sudden loss of assist to constant warning lights and disabled lane-keeping features. If these issues keep coming back despite visits to the dealership, California’s Lemon Law may come into play. This article explains, in plain language, how the law can apply to malfunctioning steering sensors and what steps to take to document repair attempts, all from the team at ZapLemon.
How CA Lemon Law Covers Faulty Steering Sensors
Steering sensors sit at the heart of today’s steering and stability systems. When they malfunction, you might notice a steering wheel warning icon, an EPS or ESC light, a pull to one side, intermittent heavy steering, or messages like “Steering Assist Reduced” or “Lane Keep Assist Unavailable.” These issues can make your vehicle feel unsafe or unreliable and can disable safety features you rely on. Because these symptoms affect both safety and drivability, they’re often more than just an annoyance.
California’s Lemon Law (the Song-Beverly Consumer Warranty Act) generally protects consumers when a vehicle under the manufacturer’s warranty has a defect that substantially impairs its use, value, or safety—and the manufacturer (through its authorized repair facilities) doesn’t fix it after a reasonable number of attempts. In many cases, the law may provide remedies such as repurchase or replacement if the criteria are met. There’s also a “rebuttable presumption” for problems occurring within the first 18 months or 18,000 miles, where certain patterns—like repeated repair attempts or 30 or more total days out of service—can help show the vehicle qualifies, but the specifics depend on the facts and the law.
Steering sensor defects fit into this framework when they are persistent and documented. Examples include repeated failures of a steering angle sensor, recurring EPS fault codes after software updates, or ADAS features that repeatedly shut off due to steering calibration errors. Coverage questions can involve warranty status, whether repairs were done at an authorized dealer, and whether the defect substantially impairs use, value, or safety. Technical Service Bulletins (TSBs) or recalls don’t prevent a valid claim; in fact, they can reinforce that the issue is known. Because outcomes depend on details, a consultation is the best way to evaluate your situation.
What to Do and Document for Steering Sensor Repair Failures
First, prioritize safety. If the steering becomes unpredictable or hard to control, pull over safely and arrange for towing. When you schedule service, describe the symptoms in everyday terms: when the warning lights appear, what speed it happens, whether the steering gets heavy, and if lane-keeping or stability control shuts off. Ask the service advisor to include your exact complaint on the repair order before you sign.
Next, build a clean paper trail. Keep copies of every repair order and invoice, noting dates, mileage in/out, the technician’s findings, diagnostic trouble codes, and parts replaced or software versions installed. Track days out of service, towing records, loaner or rental receipts, and any out-of-pocket costs. Photos or short videos of dashboard messages, warning lights, or steering behavior can be very helpful. Save emails and texts with the dealer and manufacturer, and ask for a manufacturer case number if you escalate concerns.
Be proactive during repairs. Ask the dealer to document root cause—not just “performed calibration”—and request alignment specs, calibration printouts, and any TSBs applied. If the issue returns, return to the dealer promptly so the record reflects recurrence. Avoid aftermarket modifications that could complicate diagnosis. Check your warranty booklet for coverage terms and consider a second authorized dealer if you’re not getting traction. When repeated attempts aren’t resolving the steering sensor problem, consider speaking with a California lemon law attorney about your options. ZapLemon can review your documents and help you understand next steps.
