Can Electronic Power Steering Fail?

Electronic power steering can fail. The electronic power steering system can be adjusted via software. During low-speed driving, the steering feels lighter, while at high speeds, the vehicle's handling performance is better. The driver can experience a clear road feel, with good steering wheel return performance, enhancing the vehicle's stability. The electronic power steering mainly consists of a torque sensor, speed sensor, electric motor, reduction mechanism, and electronic control unit. The power steering systems configured in vehicles are generally categorized into: mechanical hydraulic power steering system, electro-hydraulic power steering system, and electric power steering system.

Last time I was driving, the steering wheel suddenly became heavy, and I almost lost control during a turn. Only then did I realize the electronic power steering system had failed. This system uses a motor and control module to assist with easy steering, but it can malfunction due to motor overheating and burnout, aging wires causing short circuits, or software errors in the control module. The repair shop I visited mentioned common warning signs include difficulty steering, unusual noises, or warning lights turning on. Ignoring these can be especially dangerous in rainy weather or at high speeds. It's advisable to pay attention to any changes in the steering wheel's feel and have a professional technician check it during regular maintenance—don't wait until an accident happens to regret it. Repair costs typically start at a few hundred yuan, and replacing parts could cost over a thousand. Addressing issues early can save you more in the long run.

Electric power steering systems can indeed fail, which directly impacts driving safety. I once experienced a sudden steering hesitation that scared me into pulling over immediately. Common failures include torque sensor malfunctions, insufficient power supply, or motor wear, leading to heavier steering or even loss of control. Prolonged aggressive driving or rough road conditions increases failure risks. If problems occur, immediately visit a professional repair shop to diagnose error codes. Never underestimate this issue—it concerns your safety and others on the road. We recommend monthly steering response checks to detect abnormalities and prevent problems proactively.

Preventing electric power steering failure is quite simple. I usually pay attention to avoiding sudden steering wheel movements or high-speed cornering, as these actions put extra stress on the system. During regular maintenance, I focus on battery condition and wiring connections since they are the power source. When minor symptoms like slightly heavier steering occur, immediate inspection can prevent more severe damage. Basic maintenance includes cleaning sensors and tightening connectors – you can perform some simple checks yourself, but professional diagnostics once a year is ideal. Maintaining good habits will significantly extend the system's lifespan.
