Tesla did recently replace my whole body seal since my original had a similar divot and I played with it too much probably making it worse they also tightened the glass. My window seems to stick out farther than the b pillar though, I noticed in your video your window seems to "sink" under the b pillar so i'm curious if they could have tightened it more or moved in the door further because my passenger window goes way farther into the car when I run my finger from the b pillar to the window it sinks in. Where as my driver side window humps up over the b pillar which leads me to believe that also might be the source of it.
This form has been a huge help as well! I got mine used with 25k miles, The original owner wrapped it with a matte grey wrap and some other mods like painted calipers which is why I initially got it, I assume some of the modifications they made like wrapping it possibly caused the issues. But I got a Model 3 with the acceleration boost / premium interior and rear heated seats included for 31k last year including the wrap and mods I really liked so I couldn't pass it up lol. Luckily it still had warranty + the used warranty on it.
