I'm up to page 4 of the linked thread. There are more photos of a problem area on the perimeter of a door skin (unsure if it is a front or rear door).
To me ... it looks like they are not hemming the door skin around the door inner properly, leading to the door hitting the adjacent panel when opening or closing the door if the panel gap around the door isn't properly set.
Page 5 of linked thread ... There is a seam which appears to be under the top edge of the trunk lid adjacent to the corner of the window glass, which is visible with the trunk open, which looks like dog crap. I know it's not visible with the trunk closed, but sheesh, that's bad.
I've said this before ... Tesla should have contracted-out manufacture of the bodyshells to Magna, or some other company that is well experienced in doing this, although I have a hard time thinking of what other Tier 1 could do it. (again, full disclosure, anyone out there with a BMW SUV has a vehicle in which most of the bodyshell parts came from a huge Magna plant that has been one of my customers ...)
