    Forgive me if this was already covered- my 60 makes a loudish humming sound while parked and the humming sound revs up a notch when I begin charging. Normal? Thank you in advance for any feedback. Love the vehicle beyond words, just getting used to all the newness!

    Totally normal. Pumps and fans regulate cooling/heating of the pack, I presume.

    Yep. Normal sounds. Once sleep mode is brought back it will only make those sounds right after being driven, if it's really cold, or when charging. For now they are on all the time (hence the Vampire Drain loss of range when sitting).
