What does the exclamation mark next to the steering wheel mean?

The exclamation mark on the steering wheel indicates the Electric Power Steering (EPS) warning light, which disappears immediately after the engine starts. Electric Power Steering (EPS) is a power steering system that directly relies on an electric motor to provide assistive torque. Compared to the traditional Hydraulic Power Steering (HPS) system, EPS offers numerous advantages. The EPS system mainly consists of a torque sensor, vehicle speed sensor, electric motor, reduction mechanism, and Electronic Control Unit (ECU). The Electric Power Steering system evolved from the traditional mechanical steering system. It utilizes the power generated by an electric motor to assist the driver in steering operations. The system primarily comprises three major components: signal sensing devices (including torque sensor, steering angle sensor, and vehicle speed sensor), steering assist mechanism (motor, clutch, and reduction transmission mechanism), and electronic control unit. The motor operates only when assistance is required. When the driver turns the steering wheel, the torque and steering angle sensors generate corresponding voltage signals based on the input torque and steering angle. The vehicle speed sensor detects the speed signal, and the control unit issues commands to control the motor's operation based on the voltage and speed signals, thereby generating the required steering assistance.

That exclamation mark next to the steering wheel basically indicates a problem with your power steering system, likely signaling a failure in power assist. When I first saw this light, I tested it by driving, and sure enough, the steering wheel became extremely heavy, almost impossible to turn, which gave me a real scare. There are many possible causes, the most common being low power steering fluid—you’ll need to pop the hood and check the fluid level in the small reservoir. Alternatively, it could be a damaged steering pump or a faulty sensor that’s not responding properly. If not addressed immediately, you risk losing control when turning, especially at high speeds, and it becomes a major safety hazard, particularly in rainy or slippery conditions. My advice is to pull over first, check the fluid level yourself, and top it off if needed (most auto shops sell it). If that doesn’t help, head to a professional repair shop right away—don’t delay. As a side note, regular maintenance checks on the steering system can prevent such issues, saving you both hassle and money.

The exclamation mark light next to the steering wheel is on, indicating a problem with the power steering system, and the power assist may be lost. I encountered this last week while driving. At first, I thought it was a minor issue, but suddenly the steering wheel locked up, and I almost had an accident. Fortunately, I reacted quickly and pulled over. Typical causes include low power steering fluid, a faulty pump, or even a short circuit in the electronic system. Checking it yourself is simple: park the car, turn off the engine, open the hood, and locate the power steering fluid reservoir. If the fluid level is low, buy some and top it up. However, if the fluid level is normal, don’t tamper with it—take it to a mechanic. Remember, this issue shouldn’t be delayed. At best, it might cost a few hundred dollars to fix; at worst, it could lead to an accident, endangering your family’s safety. Make it a habit to check the dashboard lights before driving to ensure the steering system is functioning properly—it’ll give you peace of mind and save you trouble.

The exclamation mark indicator light next to the steering wheel flashing or staying on usually warns of a power steering system malfunction, which may cause difficulty in turning the steering wheel. Possible reasons include low steering fluid level, pump or gear issues, sensor false alarms, etc. It is recommended to stop the vehicle immediately to avoid steering failure causing a collision. Check the steering fluid reservoir level yourself; if abnormal, try restarting the vehicle to see if the light turns off. If not, contact repair services. In short, safety first, don't underestimate this light.
