I live in rural New England. I bought my M3LR last September. This summer the temperature has only rarely hit 90 degrees. Yet on numerous occasions, often with the air temperature under 85 degrees, I have walked out to the car and heard the ventilation fan running. Checking the car's state of charge, I have found that it has often lost several miles of charge while sitting in my driveway, even though the car is off. I don't have it in dog mode or any other mode that would keep the interior temperature level below a certain point. The only thing I haven't done, until recently, is to actually turn off the heating/AC system. I've resorted to doing that in the past week and no longer have the problem. But why should I have to turn off the HVAC system in the car when it is parked in my driveway? Is anyone else having this issue and do I need to call Tesla about this or is it to be expected?
