Newbie here, so be kind... Here's my story:
My dates have been all over the map too, but recent changes have been very exciting.
Model Y Long Range
Blue with black interior
19” wheels
OD: 12/13/2021
EDD: Feb 4 - 13 ! (as of 2/02/2022)
VIN : Yes! (as of 2/02/2022)
Pickup location: Mountain View, CA (16 road miles from Tesla Fremont Factory)
With tow
With FSD
At time of order, EDD was July 2022 and it stayed there for the next 2 weeks. Then, out of the blue, on 12/29/2021, I got a text saying I needed to complete my Tesla account setup to avoid delivery delays, so I did. The morning of 12/30/2021, I got another text saying I had been assigned a VIN, the car was being built that very day, and delivery would be the next day (12/31/2021). When I replied that I wasn't available on 12/31 and requested delivery first week in Jan, they asked again for 12/31. When I said again that no, that wouldn't work, they got quiet for several hours. After asking for an update, they finally said they had to release the car to someone else.
Clearly, my car was part of their end-of-quarter push, and when that wouldn't work, they were done with me - the VIN disappeared and my EDD was briefly pushed back to Jan 8 - 15, but then reset to July 2022.
During the month of January, my EDD has been bouncing around every week or so, with various 2-week windows in July, March, and lastly June.
That is until 2 days ago (2/02/2022), when I got another text saying my (new) VIN has been assigned and EDD is now Feb 4 - 13. As it's now late on Feb 4, this week seems pretty unlikely, but I'm hoping next week is it!
