My hypothesis based on what Rambino said is that the vibration is caused by changes to the algorithms which control torque vectoring. It seems plausible, but frankly I have no idea. You could be right.

Plaid Vibration around 38-42MPH....

It just doesn’t hunt for me, that master six sigma black belt (“MSSBB”) story. Many of us have driven the same routes and in the same conditions for 1000-3000 vibration free miles (and we were looking for it the whole time). Then, on those same routes and conditions, the vibration appears and stays going forward. In my case, I would say it’s getting more pronounced as the miles add up. If the MSSBB were correct, this would not be the experience.

I agree. Mine only started after 800 miles too. I was really looking for it earlier. I think something must be wearing in or loosening up.

To confirm, those of you who had the items replaced in the screen shots from several threads back, the vibration issue has been resolved? I just wanted to make sure before I schedule a service appointment.

No, not for me. I believe only one person has claimed a successful fix, where both front and rear half shafts were all replaced. A total of four.

Which part numbers were used on your car? My local service center is asking me for them so they can incorporate into my existing reservation on Jan 4th.

I found the info several threads back and sent to my SC. Thanks!

@theslimshadyist Be prepared for your SC to reject replacing these parts, as there is no "official" fix from Tesla Engineering. Don't ask me how I know....

Was it all four half shafts? The parts list shows 2x "FR, LH" and 2x "FR, RH" half shafts, but only 2 nuts and washers?

Coming up on it since the repair !!!! I am very confident mine is fixed. My VIN is 035 so one of the first delivered cars at the event in Fremont so I have been complaining about this issue since June. This is the first time despite numerous other tries I am confident

Awesome! I will recommend that, hopefully it will fix mine.

Service refused to acknowledge the vibration. They said,
"when test driving vehicle i found vehicle suspension was left on high. put suspension in normal and
left in plaid mode could not duplicate concern. when in plaid mode and using heavy acceleration
recommend suspension to be in low or normal."
Ok, that's just stupid. The car can't be driven above 15 mph in high. It automatically lowers to normal.
How did you get service to acknowledge the vibration?

FYI my plaid DID NOT have this issue the first few thousand miles but started the other day. I was able to duplicate it pretty much every time somewhere between 40-50. It was very slight but definitely didn't do that the first few thousand miles as I looked for it constantly. Anyway, I went to my service center yesterday for a couple other small issues and mentioned the vibration. A tech walked up as I was talking to service manager and knew immediately what I was talking about. He said only one other refresh has come in with it and it was a plaid. He took it for a short test drive to verify. Later they told me Tesla engineering asked them to replace both front half shafts and to send them the originals so they could inspect. Basically engineering is still trying to figure it out. They replaced with the part numbers referenced previously and the problem seems to be gone for now. The techs told me it could come back so it may not be the end all fix but I can't seem to duplicate it at the moment. We shall see. I'm not that confident and neither were they but it was very minor on my car and good for now.
