Why Does the Sunroof Rattle on Bumpy Roads?

[Deanna]

Sunroof rattling on bumpy roads can be caused by aging sunroof seals or gaskets, loose sunroof screws, or dust particles in the sunroof tracks. Below are detailed explanations of the causes of sunroof rattling: Aging Sunroof Seals or Gaskets: Sunroof seals are often exposed to rain or intense sunlight, which can cause them to deteriorate over time. Applying rubber conditioner can temporarily restore the seal's performance. Open the sunroof fully and spray the conditioner onto the seals. However, the most direct solution is to replace the sunroof seals. Loose Sunroof Screws: Loose screws can lead to rattling in the headliner or sunroof, and in severe cases, may even pose a risk of the sunroof detaching. The solution is simple: locate the sunroof screws and tighten them. Dust Particles in Sunroof Tracks: Repeated opening and closing of the sunroof can cause dust to accumulate in the track gaps. When enough dust builds up, friction occurs during operation, resulting in rattling. Use a cloth to clean out the dust and perform regular maintenance.
