I'm in very similar situation to yours. On Feb 11th my EDD changed from 2/25-3/11 to 3/13-3/31. My OD is 10/18 and I'm also in Knoxville. Looks like they're trying to squeeze us into the EOQ rush. My info:
OD 10/18; PCD 10/18; White/Black; 19"; Tow; No FSD
EDD's so far:
July
June
October
February 25th – March 25th
February 4th – March 4th
March 12th – April 9th
April 7th – May 5th
September
April 4th – May 2nd
September
March 5th – March 31st
February 25th – March 11th
March 13th – March 31st
As shown above, my EDD has spanned from February 2022 to October 2022 at one time or another. This EDD roller-coaster makes it difficult to plan finances/trade-ins/disposal of other vehicles/travel planning, ect. I understand that it is difficult for Tesla to pin down EDD's given all the variables involved. We have no choice but to be flexible with whatever they do. Hopefully if the final delivery window happens to conflict with preplanned events in our lives, Tesla will be as flexible with us as we have been with them. It will be interesting to see how this plays out.
