On my Model Y the panel fit issues include: The driver's door right edge sticks out, above the rear door about 4 mm, the thickness of the panel. The rear left door looks like it is rotated clockwise, so tight gap at the top wide gap at the bottom. Like some huge weight yanked it down when it was open. These flaws are readily noticealbe from a distance. There are several other discrepancies. And while I'm function over form (If I could save $1000 buying a dented Model Y, I'd have done it) these are noticeable and unacceptable.
In a YouTube video there was discussion of Tesla panel fit. A friend of the video maker pushed Tesla's service about as far as it could go, and then he took his Tesla to a body shop and they tweaked it that last bit. In another video the Tesla service techs were yanking and hammer (malleting?) to align the panels. It's definitely a skill that grows with experience.
One might think it's just bad quality control, but I suspect that Tesla is trying to produce cars as fast as they can and these mostly cosmetic aspects are being tolerated so as not to slow down the line. Eventually I expect Teslas will come off the line more perfect than any other car. And you might think, well there ought to be a few teams working their way through the Tesla lot fixing the panels on the new cars - and I'll bet there are, it's just they can't keep up with production and deliveries.
I've hung a lot of house and building doors. It's a three dimensional problem. A door in your house I could probably tweak into place within minutes, on a car... you don't want to make the panel look right and end up with a gap in the seal.
