What Causes the Electronic Power Steering Wheel to Feel Heavy?

[McAustin]

The reasons why the electronic power steering wheel feels heavy: 1. When the car's steering gear lacks lubrication, symptoms such as steering stiffness and a heavier steering wheel may occur. It is necessary to add lubricating oil, and in some cases, replace the power steering fluid; 2. When the tire pressure of the car is too low, the contact area between the tire and the ground increases, resulting in greater resistance during driving, making the steering wheel feel heavier. It is essential to inflate the tires promptly; 3. If the battery has been undercharged for a long time, the steering wheel will not receive assistance from the motor. In this case, the battery needs to be recharged; 4. If the car's electronic power assist fails, the steering wheel will become heavier, requiring inspection and repair at a 4S shop.
