Just want to cross-check this with other owners: I'm assuming when it's hot in the cabin and the AC is trying to catch up and cool down everything, I hear a pretty loud "whizzing" sound from outside the car (kind of like a propellor plane, or a blender). It seems to be coming from the frunk and is maybe the AC compressor. I was pretty surprised at how noticeable it was and, not surprisingly, I'll often find it doing this as I approach my car after I've been pre-cooling the cabin from the app. I believe it is louder than what I would hear on an ICE car, even factoring in the ICE sound... It will cycle off, but maybe b/c I am looking for it, I can hear it coming on again from in the cabin while driving or at a stop and even feel it a bit through my foot on the accelerator. So, just want to see if others have this as well, or is it something that needs to get checked out. In this video, the car is in an opened garage, so the sound may be amplified a bit: if above doesn't work, here's a link: TMS AC Sound Video by dockhoa | Photobucket Thanks!
