Why is the Electric Power Steering Wheel Slow and Weak to Return?

[StLaila]

Here are the reasons why the electric power steering wheel is slow and weak to return: 1. Insufficient oil pressure in the power steering pump, caused by insufficient power steering fluid or pump wear. If it's not power steering, first confirm the four-wheel alignment, and if there are no issues, proceed to check the steering clearance. 2. Wear on the steering switch return tab or the steering wheel return slot. 3. Every vehicle has angles such as front wheel toe-in and camber. When no force is applied to the steering wheel, the return force generated by the front wheels, if greater than the resistance of the mechanical steering wheel itself, will cause it to return automatically. When the angle is small, there is no return function, and speed should be considered—faster speeds make the steering wheel lighter and harder to control, with slight movements causing more significant deviations.

I've encountered the issue of weak steering wheel return before. To put it simply, it's the steering system giving you trouble. The most common cause is misaligned wheel alignment - problems with the front wheel toe angle can make the steering wheel particularly difficult to return by itself. Next, you should check the steering column bearings and universal joints; if these parts are rusty or lack lubrication, they can become stiff and unresponsive. The electronic power steering system might also be to blame: if there's a delay in the torque sensor signal, the computer won't react quickly enough to provide the right amount of assistance for wheel return. Also, many new cars have steering mode adjustments - if accidentally set to comfort mode, the return speed will slow down. Next time you're getting maintenance, remember to have the mechanic check the steering system data stream with a computer; both alignment parameters and sensor status can be clearly seen.

My car had the same issue last time, the steering wheel was sluggish to return after turning. Later I found tire problems can also cause trouble: when the tire pressure is severely low, the tread sticks to the ground like chewing gum. If the wheel hub bearings are loose, the wheel will wobble and struggle to rotate. Also, pay attention to the chassis components - if the ball joint of the steering linkage lacks lubrication or the rubber boot is aged and cracked, there will be friction and resistance during steering. If the steering wheel not only returns slowly but also vibrates with a buzzing sound, it might be internal wear in the electric power steering motor. Get it checked at a reliable repair shop immediately - steering issues are nothing to take lightly.
