I discussed this with Adam (our local tech) and he explained they had changed the fender liners. The previous ones were stiffer and did not need any support to stay up in the fenders. The changed ones were not as stiff and they had seen some of them doing exactly what ours are doing. There is an easy fix - applying a prime coat and then some epoxy type glue to the inside of the fender. He explained they had very good results from that. So tomorrow he will be working on the Alpine (volume keeps jumping up and then down by itself) and applying the fix to the fender liners.
Dragon, contact Tesla Support to get the fix.
