I have a brand new Yukon XL Denali, 3 weeks 1,200 miles on it and I confirm I have a light buffeting/rhythmic air pressure in ears too from 15mph to ca. 65mph. So seems I am case #2

I’m having the same issue in a 21 suburban LT literally from low speed to 45 seems the worst. It’s super annoying sounds like buffeting air pressure, booming but behind me.
Sound kinda like the headliner.
Already had all 4 tires road forced balanced, door alignment fixed on driver side but issue persists.
Anyone given a solution by a dealer yet?

I have a 2021 GMC Yukon XL and I have the exact same problem from 25mph+. Dealer is useless.

Here's a TSB that's worth investigating.
