RELAX! And don't seat in the car when it's parked in your garage. CO can kill you, you know.Guys,
Picked up my 2021 yesterday. Was sitting in the garage last night playing with the infotainment system. As I was sitting there, I kept hearing this deep rumbling sound. It sounds like when you are in a theater and you can only hear the bass of an explosion from the theater next to you. It came and went several times. Lasts just a few seconds. Today, I heard it again while I was at a stoplight. I'm guessing it's the heatpump cycling on and off since that's pretty much the only moving part while the car is sitting still. I'm sure the pump makes SOME noise, but this seems way too loud to be normal. Everything seems to be working fine, just the noise. Anyone else experiencing anything like this? It's loud enough that I can't believe it would normally behave this way.
Also, based on description and my experience if looks more like your battery management system ... but can be a heat pump too, the heat pump sounds more subdued though.
