Yes, for my configuration with links. I had most all of it gone with my links, then came the update and I notice it much more. Different frequency and slightly higher speed range. It’s annoying af!

Plaid Vibration around 38-42MPH....

Plaid, white on black, CF, 8/27/21, Track Pack
Seems my car doesn’t suffer from the root cause of the vibration the software is masking

Then it must not bother you that much then.
If it were me and the "new" vibration was "annoying af!" I would do everything possible to see if I can eliminate it. But, that's just me I guess.
You can stop whining about it now since "you can't be bothered".

“Can’t be bothered” because I know it would be a waste of time; time that I would never get back!Then it must not bother you that much then.

Yes, “annoying af”! My solution is to walk past the PoS as I hop into a problem-free Rivian R1T. If my $145k PoS were not only worth $53k (per Tesla), I would unload it, post haste. That’s also “annoying af”!!

Yes, same as before. The vibration completely disappears at 100% rear bias. Linear decrease as you move the slider rearward.
So totally not related to phase differences between the two rear drive units. Has this problem been seen on the MSLR?

The cold-start vibration is really, really odd. I'm probably one of the few who owned a 2021 Plaid and now a 2022 Plaid. The 2021 never did it - no 2021 does as far as I'm aware. So what is going on with the 2022-and-newer Plaids that it has this even occur? It's only a minor annoyance, of course, given it only does it for the first few minutes of a cold drive, but even so - why?
Yeah it's very strange in general. I'd be curious if anyone with a 2021 had to have their front motors or inverters replaced, and whether or not the vibration came after that. But who knows how many such individiuals are out there.

That's true! Tesla blew up my 2021's front motor while in service for the 700th time (for something unrelated). It did not have the vibration after that motor was replaced. To be fair, it was replaced before the 2022s hit, as I recall.
My MXP had the cold start grind that lasted for a minute and then abruptly stops. I always assumed it was some sort of startup calibration. It was glass smooth at any speed and any acceleration including the speed range that is the topic of this thread.

Yeah, strange considering the half shafts are the same. There are some sites that suggest something changed in the drivetrain between 2021 and 2022.

Suggesting? I can (pretty much) guarantee it. Something is obviously different in these drivetrains to lead to the start-up vibration.

Yep, it’s worse in my 2021 Plaid as well. Reported this on day one, after the supposed “fix” - when everyone else was drinking “placebo Koolaid.”
