Have you ever encountered such a situation? After you get in the car and insert the key, the key cannot be turned, the car cannot be started, and the steering wheel is locked. I didn’t know what to do when I encountered something like this. I thought there was something wrong with my car, and even hurriedly called for a repairman.
So the question is, what is the reason that causes the steering wheel to suddenly lock up while the vehicle is driving? Reason 1: Steering gear failure The official name of the steering gear is the steering gear, which directly controls the rotation of the wheels. The repair items for this Zhejiang car owner's vehicle at the 4S store were "steering gear removal and installation, and steering gear replacement."
At present, the steering systems of most household cars use mechanical hydraulic power steering systems, electro-hydraulic power steering systems or electric power steering systems. However, early mechanical steering gears have long been abandoned by most manufacturers due to difficult steering and other reasons. With the introduction of hydraulic structures and electronic units, the reliability of automobile steering systems has also decreased, and failures are inevitable.
According to professionals, the abnormal failure of the steering gear is most likely due to the unreasonable design of the water outlet duct at the bottom of the vehicle and the unreasonable design of the water outlet on the front windshield. In addition, the steering assist mechanism is not tightly sealed, causing water to enter the sensor wiring harness or inside. , which in turn causes the power steering to fail and "steering wheel locks" to occur. If this is the case, the vehicle may have a design defect. Of course, we do not rule out the possibility that problems such as the steering gear harness may cause such an incident.
