Why Does a Tesla Make a Rattling Noise Under the Car When Turning the Steering Wheel?
2 Answers
Tesla makes a rattling noise under the car when turning the steering wheel for the following specific reasons: 1. The abnormal noise caused by a damaged turn signal switch return spring: This is a sound emitted from inside the car. If you hear this noise after operating the turn signal switch and then turning the steering wheel, it is the sound of the return spring in the turn signal auto-return mechanism, which is normal. 2. The noise from the steering column dust cover: Whether stationary or moving, if you hear a noise from below the steering wheel when turning it, you should check the steering column dust cover. A lack of lubrication in the steering column dust cover can cause dry friction noise. Applying some grease inside the dust cover will eliminate this noise.
I usually drive an electric car and have encountered this situation. When turning the steering wheel, there's a creaking sound under the car, which is mostly an issue with the steering system or suspension components. Tesla uses electric power steering, and if there's dust inside the motor or the bearings are worn out, it can easily cause friction noises when turning. If the suspension ball joints or shock absorbers are worn, rough roads can exacerbate the abnormal sounds. It's recommended not to delay and directly visit a Tesla service center for a professional inspection with specialized equipment. Such issues may affect steering precision, and prolonged neglect can lead to safety hazards. Regular maintenance can prevent these problems, such as quickly checking the chassis for looseness every month to avoid sudden malfunctions during long-distance driving, making repairs more straightforward.
