yes we're having the similar issues, ours is a 2018 and initially we appealed to Tesla because the paint was wearing off and the bottom panels along both sides of the car, especially where it bow out, were fading from our gray color to almost a white, or very very light gray, That was in October of 2019. They recommended that we put on mud flaps, which we did after it was painted. In a years time that has worn off again. Now, the paint is actually chipping off on the front quarter panels, both sides. I strongly feel that the paint jobs on the Tesla were poorly done and we need to figure out how to get them to make it right.
