I had a few issues (including the pano creak) with my MS and called Tesla service. Since I live 150 miles from the closest service center they came and put my car on a flatbed. The list of fixes included pano creak, air leak from side triangle shaped window on drivers door, check lugs on wheels (which they said were tightened to 175nm), rotate the tires, AC compressor sound (which is now louder than it was before it went in) and a ding in the trim around the touch screen (they declined to fix it citing difficulty of reinstalling a new piece, though the car had a ding in the trim when I got it). I also asked if they could try and fix a key that we accidentally left in the laundry ( they stated goodwill replacement, but nothing was included when the car was dropped off today).
The work order stated they did the shim fix for the pano creak, and on my test drive I did not hear a single creak. So, at least for now, it seems to have fixed the problem. They also updated my firmware from 4.4 to 4.5. As I mentioned, they did not replace the trim piece or the key (at least not yet). The side window wind leak is fixed. The car was also washed. All in all I am pleased so far. I do wish they would have replaced the trim, but I can live without it. The key was my fault, so if they end up not replacing it I have no room to complain. The AC noise apparently a known issue as many have said it is common on the MS. I'll update how the pano creak fix is holding up in the next few weeks.
