Same issue here on my 2015 Yukon XL SLT Its a very annoying clicking feel. Almost feels as the seat slightly shifts.

I just hit 3k on ours Am i supposed to be looking for a different humming noise than the 4 to 8 cylinder annoyance?

I couldn't read through all this as my a.d.d. kicked in. I was going to sayi have a deep humming sound that sounds and feels like pressure but I noticed the annoying sound comes on when car kicks in to 4 cyl from 8. Is that what we are taking about here?
