Why doesn't the steering wheel move when the car is started?

Steering wheel not turning may be due to the activation of the car's anti-theft function, causing the steering wheel to lock. Below is relevant information about car steering wheels: 1. Steering wheel operation method: First, master a relatively safe steering wheel grip. That is, the left hand holds near the 9 o'clock position of the steering wheel, and the right hand holds near the 3 o'clock position. Both hands should firmly grip the steering wheel while remaining relaxed and not tense. The thumbs should naturally rest on the steering wheel. When turning the steering wheel, the hands should alternate in turning. When the steering wheel makes a full turn, the left hand turns halfway, and then the right hand immediately follows to continue turning. 2. Principle of the steering wheel: The rack and pinion gear set is enclosed in a metal tube, with each end of the rack protruding outside the metal tube and connected by tie rods. The pinion gear is connected to the steering shaft. When the steering wheel is turned, the gear rotates, thereby driving the rack to move. The tie rods at each end of the rack are connected to the steering arm of the steering shaft.

Last time I drove my friend's car, I also encountered the steering wheel not moving, which was really nerve-wracking! It might be an issue with the power steering system, like the electric power assist not activating or the hydraulic power pump not working. First, check the battery charge—low voltage can affect the power assist motor. Also, low or leaking power steering fluid can cause the steering wheel to lock up. If the undercarriage recently scraped over potholes, the rack might be damaged. For a quick self-check, see if the steering wheel warning light is on or listen for any motor sounds, but it's best not to force it—pull over safely as soon as possible. Some cars lock the steering wheel after turning off the engine, so try restarting to see if it unlocks. Safety first—take it to a professional shop for inspection. Regular maintenance of steering fluid and checking electrical wiring can prevent this issue.

The steering wheel not moving after ignition is quite common, mostly due to power steering issues. For hydraulic systems, check if the power steering fluid reservoir is low or leaking, which can cause the pump to suck air and fail to pressurize. For electric power steering, a blown fuse or faulty sensor signal preventing motor activation could be the cause. Mechanically, a stuck steering column or rusted tie rod may also cause stiffness. I recommend first opening the engine compartment to inspect fluid levels and the fuse box for steering-related fuses. Avoid forcing the wheel to turn, as damaging the rack would be more troublesome. Regular maintenance like replacing steering fluid periodically and checking tire pressure for balanced load can reduce risks. In emergencies, don't risk continuing to drive to avoid accidents. Remember, prioritize safety measures to ensure personal safety.

The steering wheel not moving is often related to the steering system, such as power assist failure. Electric power steering vehicles may experience issues due to motor failure, control module errors, or power loss. Hydraulic power steering can lose pressure if the power steering pump belt is loose or worn. Mechanical problems like a stuck steering gear or damaged universal joint can also be the cause. A drained battery might prevent electronic power assist from functioning. Having driven various types of vehicles, I've noticed that if dashboard lights are abnormal when starting the engine, it's usually an electronic control issue. Don't overlook simple checks: gently wiggle the steering wheel left and right to feel for power assist. Staying calm and safely parking is most important, followed by seeking professional diagnosis to prevent minor issues from escalating.
