What does an exclamation mark on the steering wheel indicate?
2 Answers
The exclamation mark on the steering wheel is the electric power steering system warning light. If the indicator light remains illuminated after the vehicle's ignition switch is turned on or during driving, it indicates a fault in the electric power steering system, which requires timely inspection and repair. Below are two scenarios when the electric power steering system warning light illuminates: 1. The warning light remains continuously on: This indicates a complete failure of the electric power steering system, requiring inspection and replacement of faulty components at a repair shop. 2. The light briefly illuminates for five to ten minutes and then turns off: This is caused by overheating of the electric power steering motor. In this case, the system enters an overheating protection mode, reducing or temporarily suspending motor assistance until the motor temperature decreases, after which normal assistance will resume.
When I see the exclamation mark on the steering wheel, my first thought is that there might be an issue with the steering system. Last time this light came on in my car, the steering wheel suddenly became very heavy, and I almost lost control while driving. I pulled over, opened the hood to check the power steering fluid reservoir, and found the fluid level was low—possibly due to a leak or long-term neglect. After adding the appropriate steering fluid, the light went off. A reminder to everyone: cars with hydraulic power steering often face fluid level issues, while those with electric power steering might have motor or sensor failures. Heavy steering at high speeds is particularly dangerous. If the light comes on, stop safely and address the issue immediately. Regularly checking the steering fluid level and inspecting the hoses for leaks during maintenance can prevent many problems.
