Abnormal Noise from WM Motor's Panoramic Sunroof?

[DeJuliette]

To address the abnormal noise from WM Motor's panoramic sunroof, the first step is to determine whether the issue lies with the sunroof sliding rails or the sunroof hardware. Applying lubricating oil for lubrication and reinforcing the hardware can resolve the problem. Below is additional information regarding sunroof noise: 1. Most modern passenger cars utilize unibody construction, where the materials used for the body differ from those of the sunroof frame and glass. Different materials exhibit varying degrees of deformation, leading to noise when the body twists and deforms on uneven roads. Additionally, the sunroof contains numerous internal components that may loosen over time due to prolonged driving on rough surfaces, making sunroof noise a relatively common issue. 2. In many cases, the noise is caused by friction between the sunroof glass seal and the metal roof panel. This can typically be resolved by spraying dashboard wax on the external seal or by cleaning the seal thoroughly and applying hand cream (such as those used by women). 3. Another possible cause is loose internal trim panels within the sunroof, which can be addressed by inserting non-woven fabric as a buffer.
