What does a steering wheel with an exclamation mark mean in a car?

A steering wheel with an exclamation mark in a car is the electric power steering system warning light, indicating that there is a fault in the car's electric power steering system. If the indicator light stays on after the vehicle's ignition switch is turned on or during driving, it means there is a fault in the electric power steering system, and it is necessary to promptly go to a repair shop for inspection and repair. The steering wheel is the wheel-shaped device used to control the direction of cars, ships, airplanes, etc. The function of the steering wheel is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. It is mainly composed of a skeleton, foam, and the corresponding installation clips or screw holes for the driver's airbag (DAB).
I've been driving an old car for a while, so I'm quite familiar with this steering wheel plus exclamation mark icon on the dashboard. It indicates a steering system warning, commonly seen in power steering failures or electric power steering system issues. The steering wheel will become particularly heavy, especially during turns or parking. Possible causes include power steering pump failure, insufficient steering fluid, sensor false alarms, or wiring short circuits. If you see this light on, it's recommended to immediately slow down and stop at a safe location for inspection; avoid continuing to drive to prevent the steering wheel from completely locking up. Safety first - promptly contact a repair shop to check the fault codes with diagnostic tools. Remember, regular checks of steering fluid and components can prevent such unexpected occurrences.
The other day while driving, this warning light came on and the steering wheel suddenly became very heavy, which really scared me! I asked a mechanic and learned that a steering wheel with an exclamation mark indicates a power steering system alert. It could be due to an EPS module failure or sensor issues, causing loss of power steering. The solution is simple: after stopping, check for any abnormal noises or leaks; if none, try restarting the engine which might clear the light, but it's still best to visit a 4S shop. Safety-wise, ignoring this warning is very dangerous as it makes steering difficult at high speeds. I recommend installing an OBD monitor to keep an eye on such warnings.
