Folks, I'm still struggling with this problem. My "whistling" noise is 100% from the rear hatch somewhere. I tried taping off all the areas in question and no such luck. At last service appointment, the noise ironically stopped when I drove with the tech! Of course, soon as I got home, it starts again. I'm not sure what else to do. I have a 2022 which does not have the Tesla lettering on the rear, so it's not that. It sounds like air is getting into the car somewhere through a small hole in one of the seals. But I cannot locate it.
Thoughts??
