I last drove my car on March 11 and was away until last night - March 22. My car was plugged into the HPWC in my garage. I got iPhone notifications on (at least) Mar 15, 17 and 19th that the car had completed charging but strangely the Mar 17 and 19 notifications came much later than they should have since charging is scheduled to start at 4:30 am and should take only a few minutes if it hasn't been used. These notifications were 4 and 6 hours after charging was supposed to have started. Last night after I got home I noticed that the car wasn't on my wifi network. So I went into the car and I noticed that the main dashboard (not the 17" screen - the main dashboard) seemed to reboot as it was dark and a Tesla logo came up - I have never seen this before. But everything looked fine and it was now connected via wifi. But at 7:00am I couldn't connect to the car from my iPhone to turn the climate on to pre-heat as it was cold today in Toronto - I never have this problem when the car is at home as it generally stays connected to my wifi. I left at 7:30 and the car was okay and didn't appear to be in a state of deep sleep. I am now able to connect to my car with the app. Can anyone explain this behaviour? Note that I have Power Saving turned off and Always Connected checked.
