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.

If your steering wheel feels sluggish in returning to center, start with the simplest checks. First, see if you have a heavy steering wheel cover or some odd decorative disc installed—these extra weights can affect its return. Next, try inflating both tires to the standard pressure; a difference of over 0.3bar between the left and right tires can pull the steering wheel. It’s not uncommon for the steering column cover to get stuck by floor mats, so bend down and check for any interference. Those who’ve upgraded to larger wheels should take note: overly heavy rims can also increase the return burden. Lastly, a reminder for those in northern regions: thickened grease in the steering system during winter is another common cause.

Slow return of the electric power steering system is mostly related to sensor signals. If the steering angle sensor under the steering wheel gets damp or has loose connectors, the ECU won't know whether to stop. Some vehicles even adapt to driving habits - long-term one-handed steering might make it mistakenly think you dislike quick return. Loose steering gear mounting bolts can also cause weak return, which becomes obvious when the car is on a lift. By the way, have you recently replaced any suspension components? Overly raised body modifications can alter steering angles, naturally affecting return force. If the cause remains elusive, try resetting the power steering system by disconnecting the negative battery terminal for three minutes and reconnecting it.
