What are the solutions for the sunroof noise in ATSL?

If the Cadillac ATSL has sunroof noise, you need to clean the sunroof rubber seal and spray some rubber protectant to solve the problem. If the noise is caused by loose sunroof structure, the method of adding non-woven fabric can be used to fix it. Precautions for using the sunroof: 1. Before opening the sunroof, make sure there are no obstacles on the roof that may hinder the sliding of the sunroof. 2. Try not to use the sunroof on bumpy roads to avoid damage to the sunroof and sliding rail components due to vibration. 3. It is strictly forbidden to open the sunroof on rainy days or when washing the car to prevent rainwater or water droplets from causing the rubber seals and metal parts inside the sunroof to age and rust easily.
I also encountered the issue of ATS-L sunroof rattling, and it took me several attempts to fix it. First, check if there are any small stones or dust stuck in the tracks. Clean them thoroughly with a soft brush and apply specialized grease—the effect is immediate. If the rubber seals are aging and creaking, try applying some rubber protectant. Later, I discovered that the rear bracket screws were loose, and the noise only stopped after removing the sunroof glass and tightening the screws. If these methods don’t work, it might be due to a deformed sunroof frame or worn sliding tracks, in which case you’ll need to visit a 4S shop. I recommend regularly cleaning and maintaining the tracks, especially for those who park under trees often, as accumulated tree sap and dust can quickly lead to rattling.
