I am experiencing a popping sound from sunroof area when the car goes on an uneven surface. For example when going up a steep driveway and I guess the chassis is bending slights. I hear this strong pop/ cracking noise only once and then it won't appear for a day or so till other uneven road surface... Anybody else experience that?

Do a search in the forums. This is a common problem with the pano roof and I believe there is a service bulletin about the issue. I had mine fixed under warranty and I believe they used some new screws, lubed and retightened everything. Problem fixed.
