This will be my fourth Tesla. My first 2012 MS85 was a nightmare experience because the company was brand new and everything was difficult, and understandable and forgivable. They missed a half dozen delivery estimates, but the car finally arrived and I absolutely loved it. My second MS delivery was a piece of cake. Ordered the car and took delivery in less than one month on 2015 MS85D. Our third Tesla was also a piece of cake with no glitches or delays on 2018 RWD LR M3. So our previous two Tesla deliveries were flawless with no problems. This last experience has been the absolute worse nightmare experience of my lifetime, and has left a very bad taste in my mouth. I fully understand Tesla is experiencing supply chain issues similar to other Auto OEMs, but the lack of communication with customers like me who have been loyal and faithful to the brand is entirely unacceptable. I have had my last three EDD's yanked away at the point I reached the front end of the delivery window with no explanation. Entirely unacceptable. I gave the Tesla representative an earful yesterday, but do not expect any positive changes. I sold my MS in August in anticipation of LR delivery, and have been without a car for 5+ months now.
