Driveline vibration saga continued (aka, Update) -
Dropped my Plaid off at 7:45am this morning (Bellevue, WA SC), and was greeted at my car by the Sr. Service manager and shop manager - They came out to the car before I even got out of it (long story)! Good thing I brought two dozen "Top Pot" donuts with me!
1. Shop manager and I took a drive to confirm vibration. He said he has felt this before in earlier Plaids he drove, but I was the first in his shop to bring it in. I shared the TMC history and let him know more were coming to his shop the first week in December. He wasn't surprised, as he was expecting this. He will reach out to Tesla Engineering, so I guess I'm the test case. I shared with him that I'm taking a VIN poll on TMC, to help isolate the VIN range affected with this vibration. Please visit this thread and vote, if you have the issue described below (as I reported to the SC).
We are trying to understand how wide-spread this issue is, and to see if Telsa resolved the issue "in production" cars after a certain VIN range. Please provide as much color as you can, by commenting and voting! - jebinc

2. We also talked about HV pack replacements, and he said he has done two Plaid's already. No issue like this with mine, however.
3. The first thing he is going to do is to rule out bent rims; get this, by installing 21s on it! He doesn't think this is the problem, but needs to be able to tell the mothership what he already ruled out!
4. After 30 minutes of chit-chatting and driving, I left in a low mileage Raven, same color as my Plaid - nice touch.
As a reminder, description of the issue:
- Vibration felt in accelerator pedal; passenger’s also feel it on the floor and through the console.
- Occurs: between 38 – 58+ mph
- Conditions: Constant speed (e.g., holding 43-47 mph +/-), or under very slight acceleration in this range, especially after transition from regen (green bar) to slight acceleration (bit of gray bar)
- Frequency: Occurs more than 50% of the time; varies in intensity from drive to drive
- Started: Developed around the 2000 mile odo mark (for me)
- “Feels” more of an electrical issue (DU, inverter, controller of some sort) than mechanical, but Tesla SC “supposedly” replaced half shafts and did a 4-wheel alignment (Did not fix the problem)…
- Not tires as condition existed with delivered summer tires and Tesla Bellevue SC installed all season Continentals
- Not alignment as car tracks fine, although yoke is not centered; now skewed slightly right (after Renton SC visit).
