What are the common causes of frequent electronic power steering issues in the Hongguang S?
3 Answers
Common causes of electronic power steering failures are as follows: Air in the system: A large amount of air in the power steering system can cause abnormal car steering. Electrical faults: Poor contact in the internal connectors or motor of the electronic power steering. Control valve failure: Foreign objects in the steering hydraulic lines can cause the steering pump flow control valve to stick, or excessive wear of the steering gear piston cylinder and poor sealing of the oil seal, leading to control valve adhesion or damage. Hydraulic system failure: Loose connections in the power steering system can cause steering fluid leakage, overloading the steering system, resulting in excessive wear of the stator and rotor inside the steering pump, leading to irregular oil movement and abnormal noises.
My Wuling Hongguang S has been running for over three years, and the electric power steering has been acting up from time to time. At first, the steering wheel became extremely heavy, making turns particularly difficult. Later, when I took it to the repair shop for a check-up, the mechanic said it was due to dust accumulation on the steering torque sensor causing inaccurate signals. This part is located under the steering column and is especially prone to dust. Additionally, the steering wheel position sensor might also be problematic, as it can get damp and short-circuit during rainy days. The most annoying issue is the poor wiring connections—loose plugs or aging wires can cause the power assist to come and go. Some in the car owners' group have even experienced control module burnout, especially noticeable in summer when the AC causes voltage fluctuations. Remember to regularly maintain and inspect these critical parts—don’t wait until the steering wheel locks up to regret it.
Recently resolved the power steering issue on my Wuling Hongguang S, and I've identified four common failure points: First, sensor sensitivity degradation is quite common, especially in older vehicles; second, electrical circuit problems including fuse blowouts and wire oxidation are particularly noticeable during rainy seasons; steering motor brush wear can also cause jerky sensations, which requires professional equipment for diagnosis; controller program abnormalities may lead to random malfunctions, and firmware updates can resolve this. Avoid holding the steering wheel at full lock for extended periods when parked, regularly clean engine compartment debris to maintain cooling, and refrain from forcing through water during rainy days. It's advisable to have the power steering system's operating voltage checked during every maintenance service.
