Plaid Vibration around 38-42MPH....
- Thread starter cytranic
- Start date
I am thinking the software would be an unlikely fix since in most cases the vibration is caused by imbalance in rotating components. It can be caused by the motor when its running on say power frequency it wasn't designed for but then all plaids would be having it unless there are certain batches of motors with a problem. Over on Taycan forums, they are replacing front motors to fix the vibration...
Ultimately I suspect they know what it is, but its too expensive to fix so they just punt it until you learn to live with it or force them to do buyback.

We've known for a long time that software can effectively hide the problem. If you put the car in track mode and rear torque bias the vibration goes away. They are essentially doing something similar in this update most likely. I agree the problem is hardware but I think it can be mitigated with a software fix.

I took 2023.44.1 on for another short spin. At least for me, the vibration at mid speed under mild acceleration is all but eliminated if not gone completely. It is a nonissue at this point for me. The initial vibration that goes away within a minute after a cold start seems to be reduced at least 50%, but this one was always a bit variable.
My biggest complaint at this point that comes to mind is the relative lack of functionality on the left driver display\screen and lack of customizable "cards" and data. So all in all not much to complain about at this point.

SMT is a bit buggy on the engine power number for Plaid. I guess in need to be checked on a LR with two motors? It was possibly change on the latest SMNT version but before thaqt the numbers shown was not really usefull.
Anyway, only delivering power to the rear motors will probably induce issues on winter roads (which I have 6 months a year).
Do not sound like a sulotion I would prefer. I went to 4WD vehicles >20 year back, and the change was due to a reason.
Currently away but I can check with SMT when back in the end of the week (currently on 32.9)
The service bulletin only mentions changing things on Plaid variants. So, it is possible there is no change for the LRs.

This will doubtless be a tough question to answer, given once you know, you know.., but do you think if you weren't aware of the vibration issue between ~37-50mph, would you (and you specifically), as a new driver on 2023.44.1, notice it at all now, moving forward?

You mean there's a chance us lowly LR folks will keep our range?
So that means that front motor is the problem. Batch of motors out of spec perhaps?

Maybe, but if you do not power the motor or redue power to it and vibration disappears and if you power it vibration appears its logical to assume it could be the motor...

I am fairly sensitive to noise and vibration but there's no way as a new driver with 2023.44.1 I would be aware if not for this thread.

Yes, absolutely. I've long thought it's the motor, and evidence suggests it most definitely is. My response is to your point about it being potentially a bad batch. I'm going to say nope, - it's a car-wide issue, which is why all Plaids from 2021-2023 are getting the update.
That's great to hear!

Don’t act surprised by the delay and wait. We all knew these are low volume cars that Tesla assigns next to no resources to. The spend goes on the high volume models that Wall Street tracks!

When it comes to FSDj and this vibration, I’m “two rays of sunshine”…. One ray is out of phase with the other - resulting in complete an utter darkness!

Logical, but if I recall, letting off power a bit at about 40, the vibes are still there. I don't know of that is true with foot fully off accelerator

I still don’t get why I feel it in the pedal but not on floor board, if the pedal is not physically linked to the non existing carburetor. It’s accelerator by wire right?
