GC has the panoramic sunroof. Whenever the vehicle is warm, i.e. come back from shopping and outside is 80 degrees or above, the sunroof makes a horrible grinding noise. I have taken it to the dealership twice for the issue and it still is not fixed. The second service I explained it happens when it is warms first time they "could not replicate issue" and showed them the video I took of it happening with sound. When I picked up the car, hopped in and popped the sunroof, grinding noise still there. I did not drive away with the vehicle, still in dealership.
