I asked the same question a month or so ago. Mine is a '22 as well and has been doing it since day one. I had a 2020 with the 2.7l turbo as well and there was no such noise, I know they have revamped the engine since then, so I don't know if that has something to do with it. I've gotten used to it, but it's still a bit concerning. The feedback through the radio speakers comment nails it, I couldn't really figure out a good way to describe it. Hopefully it's nothing that's going to cause problems down the road.

After listening to all the videos and audio clips in this thread, your whine is definitely different than mine. Mine only makes a whine when I am accelerating, and its definitely the turbo spooling. The whine in this thread sounds more like an electrical whine or something. Hope you get it figured out soon.
