Electric vehicle owners are seeing a new kind of dashboard warning: “Steering Assist Reduced” or “Steering Assist Failure.” If you’re getting this message repeatedly, or losing electric power steering unexpectedly, it can feel alarming and unsafe. This article explains how California’s Lemon Law can apply to EV steering assist issues and when it may be time to contact a California lemon law firm like ZapLemon for guidance.
California Lemon Law and EV Steering Assist Warnings
California’s Lemon Law (the Song-Beverly Consumer Warranty Act) protects consumers when a new or certified pre-owned vehicle under warranty has defects the manufacturer can’t fix after a reasonable number of attempts. In plain terms, if your car keeps going back to the dealer for the same problem and the problem affects the car’s use, value, or safety, you may have rights to a repurchase or replacement. This can apply to EVs just as it does to gas vehicles, including defects in electric power steering systems.
A “Steering Assist Failure” warning can be more than a nuisance. On many EVs, electric power steering reduces the effort needed to turn the wheel. When assist is lost, steering can become heavy—especially at low speeds or when parking—raising safety concerns. Owners often report intermittent warnings after DC fast charging, in cold weather, or following software updates, along with symptoms like steering wheel vibration, warning chimes, or a sudden increase in steering effort. The root cause may be software (EPS control module programming), a faulty torque sensor, rack-and-pinion issues, low or failing 12V battery, bad connectors, or a steering angle sensor that needs calibration.
California’s Lemon Law presumption may apply within the first 18 months or 18,000 miles if certain benchmarks are met, such as multiple repair attempts for the same defect or significant days out of service. Even outside the presumption period, you still may have claims if the defect persists during the warranty and the manufacturer can’t fix it after a reasonable number of tries. Over-the-air (OTA) updates, module reprogramming, and software “resets” done by the dealer can count as repair attempts, depending on the facts. The key is consistent documentation so your experience is clear and provable.
When to Call a California Lemon Law Firm Like ZapLemon
If the steering assist warning has appeared multiple times and the dealer hasn’t permanently fixed it, consider speaking with a California lemon law firm. Signs it may be time: two or more repair visits for the same steering issue, the vehicle has been in the shop many days total, or you’ve been told “no problem found” despite recurring warnings. Safety-related defects—anything that could compromise control of the vehicle—often warrant earlier action because of the potential risk.
Before you call, gather helpful information: photos or videos of the dashboard warning; dates, mileage, and driving conditions when it occurred; all repair orders (ROs) showing “concern, cause, correction”; and any dealer notes about software updates, TSBs (technical service bulletins), or parts on backorder. Save tow, rental, and rideshare receipts when the car is undriveable or at the dealer. Avoid clearing codes on your own—those freeze-frame data and fault codes can be important for diagnosis and your claim record.
A firm like ZapLemon can explain the process, timelines, and what “reasonable number of repair attempts” might mean for your situation. They can also help you understand options such as a repurchase, replacement, or cash-and-keep settlement, depending on the facts and the law. Every case is different, which is why a consultation is important.
