Some update: I dropped my car off to have the new design / tolerance half shafts installed. Let's hope it works!
Interesting: My loaner car is a '23 Model S LR with 3k miles.
It has absolutely no vibration. I tried everything to get it to vibrate but couldn't find any. I drove in medium, even high (from below 35 mph) and there is no vibration at all.
Built 12/22. Running 2023.2.12 software. 19" wheels.
Of course, it still has other issues, like the seat belt was installed backwards at the factory.... But you can't have everything.
