Why Did the Steering Wheel Suddenly Stop Turning?

[McNova]

There are several reasons why a car's steering wheel may become immovable: the steering lock mechanism is activated when the car is turned off; the steering gear lacks lubrication, the steering gear rubber boot has come off, or the steering gear teeth are loose. Below is additional information: Steering Lock Mechanism: The steering wheel may become immovable when the steering lock is activated after the car is turned off. If the steering wheel is turned while the car is off, the steering mechanism will automatically lock, making the steering wheel immovable. This issue can be resolved by turning the ignition key while simultaneously turning the steering wheel, which will release the steering lock and allow the car to start normally, with the steering wheel functioning as usual. It's important to note that if the brake pedal is pressed repeatedly while the car is off, it may also become stiff. This happens because repeatedly pressing the brake pedal while the car is off expels air from the brake booster, creating a vacuum inside, which makes the pedal hard to press. This is a normal occurrence, and the brake will return to normal once the car is started. Steering Gear Lacking Lubrication: If the steering gear lacks lubrication, the rubber boot has come off, or the gear teeth are loose, the steering wheel may also become immovable. In such cases, it is advisable to visit a repair shop or a 4S dealership for professional inspection and repair.
