I'm replying to the Window gap in the rear left by the trunk people talk about. I have this as well and it seems common, but this isn't normal. Friend of mine has 2021 M3 he got a few months ago, his window gap is perfect.
From looking at it much closer, the entire rear glass pieces is slightly shifted at an angle. The gap gets closer/smaller on the left by the roof frame/line, and I assume that means the front glass roof is also misaligned, because it is fairly straight the gap between the rear window and sun roof glass.
Seems like the only true fix is the ability to actually suction cup/lift both pieces of glass off, and put new sealing for both and replace/set the pieces back into place aligned.
This is clearly a QC/alignment and poor tolerance issue with the factory. As I mentioned, and another person noted looking at a bunch, not all have this, and my friends has perfect alignment on his.
I have a service appt to have them look at this, the center console/driver's side rubbing...and also a similar gap another person mentioned at the front bumper by the right headlight/frunk where it meets, slightly raised and gap is larger compared to other cars, left side of it...friends car again for comparison.
Will report back, I have an appt and see what they say/do about any of this. Grey car is my friends M3 right next to me at the charger at work as gap reference.
Replying to my own issues as a follow up so others will know how Tesla responded to my issues. As usual, most are "in spec." Yeah right. If you say so.
Took me 6 weeks to get an appointment, they kept canceling it. Then they had to order a part which took a week or so. Speaker grill had dings in it when I picked it up at delivery. So that was replaced and they had nothing to say about that one.
My driver's seat, which many people have the issue with a big gap on the passenger side and the driver's side barely rubbing, service department of course said it was in spec, put "lube" on seat so if it rubs it won't be a wear spot/issue. All I know is that it is documented, so if there is a problem later, they are on the hook and not me with the "in spec" response.
Same for the Rear window misalignment. They say all Tesla's with power lift have that blah blah..when I know this is a complete lie. Coworker, and plenty of other Model 3 LR/SR vehicles with power lift for 2021 don't have this at all. Pretty obviously that if you get one piece of the glass on the roof, windshield, sunroof or rear window off, they are all going to be off. I sent them photos of my coworkers car which it is night/day. Clearly the windshield or sunroof is slightly off, to make the gaps nearly align, they put the rear window on and is is a few mm shifted to the right. No leaks though. We've had like 2ft of rain the past month since I picked it up in FL..if it was going to leak it would have happened. But...i isn't a huge issue, but again, if there are any leaks etc...I had it documented. They will need to deal with it worse case. That isn't spec.
They did fix my front bumper/quarter panel alignment issue and got it tighter and fixed the sunken door handle. Most of these things are all well documented with people and Tesla just refuses to perform and have any real quality/pride and tolerance with their product sadly compared to other "premium brand" of vehicles.
At least I did get a loaner 2018-2019, early VIN, must have been a 2018 M3 with full FSD. Realized what piece of garbage and how it isn't worth $20/month, nonetheless $200 or $10K.
You offer me Beta for $100 a month FSD, I will take them up on that. Pretty sad. So many silly things that FSD does besides trying to always stop at green lights, sketchy driving...and it is on the latest firmware...radar car obviously. Some good things though, like no auto wipers etc...otherwise...not impressed at all with FSD and what you get over regular autopilot.
Good luck.
