What Causes Steering Wheel Failure?
1 Answers
Steering wheel failure is caused by steering gear malfunction or anti-theft system activation. Below are the details about steering wheel failure: 1. Steering gear malfunction: The steering gear, officially known as the steering mechanism, directly controls the rotation of the wheels. Abnormal failure of the steering mechanism is likely due to an improperly designed drainage outlet at the bottom of the vehicle from the windshield washer tube, combined with poor sealing of the power steering system. This can cause water to enter the sensor wiring harness or internal components, leading to power steering failure and "steering wheel lock." If this is the cause, the vehicle may have a design defect. Of course, the possibility of steering mechanism wiring harness issues causing such incidents cannot be ruled out. 2. Anti-theft system activation: Generally, when the car is turned off, rotating the steering wheel in one direction by a certain angle will produce a "click" sound, after which the steering wheel can no longer be turned—it is now locked. The principle is that there is a pin inside the steering wheel; when the key is removed, even a slight rotation of the steering wheel causes the pin to pop into a hole, locking the steering wheel. In this state, the steering wheel cannot be turned, and the ignition switch cannot be operated, ensuring that malicious individuals cannot steal the car.
