yesterday i went into my garage and my model S was off and plugged in on a trip charge. There was a soft wlectricwhining noise I hadn’t heard before. It kind of sounded like the whine you get when the A/C is on all the way but a little different. I took our ICE on the trip, didn’t want to break down on the road. After I go home tonight it was louder than yesterday....plugged in and turned off. Anyone else had this? What is it? I HATE that I can’t talk to my local service center BTW. You sit on hold for over a half an hour to speak to the national call center....and Tesla no longer washes or vacuums the cars when they’re in for service...and they didn’t supply me with either new battery for my fobs like they said they would when I was in the last time. Service has gone down hill but I digress.....
