Wanted to share a similar issue I had with our 2020 Model X. I'll try to make a long story as short as possible. At delivery, we had some paint issues on the back left lower quarter panel and some other issues on the back bumper. This also was noted on the due bill and we made the decision to take delivery and keep the car with the hope that Tesla would take care of the problem.
Took the car in three weeks ago and we were eventually told that they couldn't fix the issues on the back bumper, they had to completely repaint the rear bumper. After about 2 weeks the car was ready and when I went to inspect it, the rear bumper looked worse than when we dropped it off! There were a minimum of 6 places where there was dust/dirt under the clear coat that was clearly visible. The car is white, so this certainly makes them more visible, but still. Not to mention that the colors were pretty obviously not a good match. On top of that, they had scratched the back left tail light and rear hitch! Needless to say, I was furious. Told the service manager I wasn't sure I even wanted the car any longer, but we struck a deal to try and let the body shop fix it again.
Fast forward one week, I go back (mind you, it's 100 miles each way for me to get to the local Tesla 'dealership') after the service manager says that the car is ready and "I inspected it and didn't see any issues you should be concerned with". I got on site on a Saturday morning and, upon inspection, there was STILL debris visible under the clear coat of the paint and the color difference between the bumper and the quarter panel is visibly different. In fact, one of the areas I pointed out to them was not even fixed during the 2nd visit to the body shop.
My wife and I absolutely love the car, but I'm fit to be tied at this point. I feel like all of these issues have diminished the value of a brand new car, and I'm waiting to hear back from them as to what the solution to the problem might be. I've told them as much and stated that we'd like to have a new vehicle, but I don't have much hope this will happen. I don't want any more repairs done by a local body shop, to be sure. Maybe take a factory painted bumper replacement? But that doesn't give me much comfort with all of Tesla's documented paint issues.
I've threatened the lemon law as a previous poster has suggested and I think may end up having a case. We are in WV and the lemon law kicks in after 30 days in the shop or three attempts to fix the same issue.
Appreciate all of the good advice above and just wanted to share our story with everyone, for better or for worse.
