I experienced this same problem over the last 2 mornings and want to see if anyone else have seen it, and what the solution may be to solve it. I always start my heater about 15 minute before driving off in the morning using the app. In the past 2 days, I noticed that the HVAC would turn on, but would turn itself off after 10 seconds. I tried it for like 5 times and same results. The car has good connectivity and remote honk works. I then go to the car, unlock it, and then turn it of from the console with (stay on) and it is just fine. Model S 100D 2017.50.3 Yesterday morning: Not plugged in 68% battery (HVAC turned off after 10s) Yesterday afternoon: Plugged in 80% battery (HVAC stayed on) Today morning: Not plugged in 47% battery (HVAC turned off after 10s) I rebooted the console when I got to work, will see if it is still a problem later.
