Ordered my Model Y in January 2022. Just had multiple email exchanges today with my Tesla sales guy in the greater Seattle area about whether they would honor their representation at the time of the order that the charging cable was included. Response I got back was that he is as confused as many of us are and was not willing to make any statement until he gets more info from Tesla.
All I can say is that I wish I were an attorney as I can see a lucrative class action suit developing if Tesla backs out on providing people who have had cars on order for months with a means to charge their cars, particularly given that the necessary items are currently out of stock. It's like a dealer delivering a conventional car without a gas tank, and telling me I can purchase one, but they are on back order.
