So i have taken my car in twice for my sunroof rattling alot, and each time the dealership said that its because its winter and it cold, which could be it. but this past week has been warmer, like 40-50, and it still rattles. So i go to work today, and when i leave its raining out, and on the drive home the sunroof is still rattling, and then i start to feel water dripping on my hand. Im like wtf. So when i get home, i start checking things and water keeps dripping from the onstar speaker that is next to the sunroof button, and i see water stains in the headliner. so this time they cant tell me stupid **** that its winter and cold. I just needed to vent.

 

wow...i hope they make it right. fortunately i have not had an issue with mine leaking

 

Sunroof drains are plugged or pulled off....common problem it appears. They should fix that no problem.
The rattling....who knows, my sunshade rattles like a bitch but I am going to get it fixed (I hope) once it warms up a bit here. -26*c this morning, brrrrrrr.

 

needs a sunroof module and glass adjustment...2-3 hour job
