What does it mean when a steering wheel-like light comes on in the car?

When a steering wheel-like light comes on in the car, it indicates a problem with the vehicle's power steering system. At this point, the steering wheel may become harder to turn or completely fail, requiring the vehicle to be stopped immediately for inspection and repair. The vehicle's steering gear requires regular replacement of lubricating oil, and the vehicle should be lifted periodically to check for oil leaks in the steering gear. Any issues should be promptly repaired or replaced. After replacing the steering gear, it is necessary to add power steering fluid and perform a four-wheel alignment before the vehicle can be used normally. If the vehicle's steering becomes heavy, the steering gear should be checked for problems.
That day I was driving on the highway when suddenly a steering wheel icon popped up on the dashboard, and my heart skipped a beat. This kind of warning light usually indicates an issue with the steering system, most commonly a problem with the electronic power steering. I've encountered it twice—the first time it was due to poor contact in the power steering motor sensor, and the second time was worse, with the steering column lock module failing outright. Pay attention to the light's color: yellow means you can drive slowly to a repair shop, but red requires pulling over immediately and calling a tow truck. If you keep driving, the steering wheel might suddenly become heavy or even lock up, which is extremely dangerous. I recommend checking the power steering fluid (for hydraulic systems) or electrical connectors (for electronic systems) right away. If you can't fix it yourself, get it to a repair shop immediately—never take steering issues lightly.
The other day when I started the car, a yellow steering wheel icon popped up. I checked the manual and realized it was a steering system fault warning. The mechanic said nowadays nine out of ten cases are due to electronic power steering module failure, especially for cars that are five or six years old. It could be sensors clogged with dust, or the steering angle calibration being off. He taught me a simple self-check: gently turn the steering wheel left and right while stationary to listen for any abnormal clicking sounds, then test if the steering effort has noticeably increased. He warned that if the light turns red or the steering becomes jerky, never drive the car further - some vehicles will directly enter protection mode and lock the steering wheel. He casually showed me repair photos on his phone, including cases with burnt wiring harnesses.
Old Zhang encountered this issue before. When the steering wheel warning light came on, he was puzzled at first. Then he almost couldn't turn the wheel during a bend. Later inspection revealed a short circuit in the electric power steering motor, costing over 2,000 yuan to repair. The technician said this light is often linked to the ESP system - if the stability control sensors fail, it can trigger the light too. Additionally, abnormal tire pressure or severe wheel alignment deviation may cause the ECU to misjudge excessive steering resistance, occasionally illuminating the warning light. The key is observing whether the light flashes or stays steady - flashing might indicate intermittent faults (try restarting), while steady illumination requires immediate attention. Remember, steering issues are never minor problems.
