Can Electronic Power Steering Fail?
2 Answers
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.
