The reasons for the failure of the multi-function steering wheel of the Baojun 730: Generally, it is due to the overload operation of the steering system, causing excessive wear of the stator and rotor inside the steering pump, resulting in irregular movement of the oil inside the pump and producing abnormal noise. Common problems with power steering failure include: heavy steering, abnormal noise during steering, and oil leakage in the steering system. Immediately lift the throttle: First, immediately lift the throttle and shift the gear lever into a lower gear. Second, evenly apply the parking brake. Third, when the speed significantly decreases, step on the brake pedal to gradually stop the vehicle. Issue warning signals: While taking emergency measures, it is necessary to issue warning signals to other vehicles and pedestrians on the road, such as turning on the hazard warning lights, headlights, honking the horn, or making hand gestures. Quickly release the throttle: If the power steering system fails and you suddenly find the steering is very heavy, quickly release the throttle, reduce the speed, forcefully operate the steering wheel, and park the vehicle at an appropriate location.
My Baojun 730's multi-function steering wheel has malfunctioned several times after prolonged use. Typically, button sticking or poor wiring contact are the main culprits, especially when dust gets into the button gaps causing insensitive contacts. Wires near the steering column tend to loosen, leading to disconnection on bumpy roads. Blown fuses are also common; replacing them in the small box under the driver's seat usually fixes it. When volume control, track switching, or call answering functions fail, I have to rely on manual operations via the center screen, which is inconvenient and distracting while driving. Disconnecting the battery for a few minutes sometimes helps, but frequent failures may indicate a faulty control module—best to visit a professional repair shop promptly to avoid erratic button responses interfering with driving. Regular cleaning of buttons with alcohol-dipped soft cloths and checking fuses ensures stable voltage.
