Parked the car in the garage after a 20 miles easy drive today. Plugged in. The temperature outside ~78F, and ~68F inside the garage. About 6 hours later I'm still hearing a faint humming noise, the kind I usually notice when the car is being charged at home off the HPWC (the car is not charging during this time per schedule) and when the battery is being preconditioned. I've never heard this noise going for this long in 4 years of ownership. It also like the car is not going to sleep (the app connects to it instantly) and has drawn about 5 miles in 6 hours so far (it's not drawing power from the HPWC). I also noticed the front air intake flaps are closed (not sure if it's normal in this scenario). Submitted a bug report per Tesla support line. The sound is still going and not sure if it would ever stop. My guess is the coolant pump or faulty thermostat, but I'm not sure. Whatever keeps running should not be on for this long.
Any help would be appreciated.
