What Causes the Rattling Noise from the Sunroof on Bumpy Roads?

[Hubert]

The rattling noise from the sunroof on bumpy roads is caused by vibrations between the sunroof and its sliding rails. It is recommended not to fully open the sunroof on rough roads, as excessive vibrations between the sunroof and rails may lead to deformation of related components or even damage the motor. Below are some precautions to keep in mind when using the sunroof: 1. When opening the sunroof, ensure there are no obstacles on the roof that could hinder its upward or backward movement. Otherwise, the motor may overload and burn out, or the sunroof glass surface may get accidentally scratched. 2. Always operate the sunroof correctly when opening or closing it. Improper operation can cause excessive current in the sunroof motor, leading to motor burnout. 3. Avoid opening the sunroof when driving on extremely bumpy roads. 4. Do not direct high-pressure water jets at the sunroof's sealing strips when washing the car, as this may deform the seals and cause leaks.
