2023 Yukon Denali squeaky sound coming from back

[Bholcomb]

Have a brand new 2023 Yukon xl Denali and after only two weeks I started hearing a squeaky sound coming from the rear window (I think). It will happen over bumps or on a rough road. Sometimes if I open the lift gate glass and slam it closed it will stop but it eventually comes back. Very annoying! Any suggestions?

I get a noise in the back, too, in my 2021 Suburban.  I would characterize it as more of a "clunking" noise. 

It's either the lift gate glass or the doors on the deck floor.  I can't really nail it down.

It seems worse if I have gear in the back (which suggests the floor) but it also seems worse when I have the windows open (suggesting air pressure on the lift gate glass).
