High pitch noise when driving over 40mph

[sc_buffalo]

I've been intermittently hearing a high pitch noise when driving (2024 R1T) over 40mph. Thought it might be the widow and had a service tech come out and ruled that out. He confirmed hearing it too and said he thinks its from the propulsion system but wasn't sure (also wasn't something he had encountered before too).

Anyone else have a similar issue? I can't seem to narrow down when/why it occurs. I've tried testing the AC, accelerating, etc. Only thing is that it can happen starting at 38mph, consistent at over 40mph.

Pretty obscure issue but thought I'd ask here. Thanks all!

Issue with the tires maybe? Check the tread, rotate and see if the noise changes?

I'll also add, I took it to the service center and as expected it didn't occur. Tech who did hear it seemed to rule out ball bearings so
