I have a 2017 MX and I have been waiting three weeks now for replacement plastic rear wheel fender flare moldings that surround the wheel openings. When my Mt Kisco, NY SC placed the order they originally quoted me no more than a few days to get these parts but as each week passed their story has changed. They are now telling me that this is a third party supplier part and none of their distribution centers nationwide have these spare parts in stock right now, and thus the delay. I challenged that explanation by saying that that cannot be correct because brand new MXs are coming off the assembly line with these parts as we speak so the supplier must be currently making them available. The SC was not able to form a response to this and I'm still waiting on the parts. In short, my conclusion is Tesla is not providing spare parts out to their distribution centers in order to meet their new unit production numbers and thereby short-changing all current owner cars causing part delivery delays. Is/has anyone else experienced similar part delays for either their Model S/Xs and are you being "fed" the same story through your SC? My concern is if I ever have a more serious accident it could take many months before all the correct parts could be sourced to fix the car down the road.
