I have the 2017 Tahoe LT with EOM tires and updated 18" wheels. Just went on a 800 mile road trip for Spring break and noticed no buffeting or vibration. Cruise control around 72-75 most of the trip and did get it up to 85 to 90 on a few "passing" zones. No issues.

2016 SLT, 19K Miles, sunroof, 20" OEM wheels - no issues I will say I do not like driving around town with it in 4cyl mode.
Turn it off - when driving off select transmission setting "L" and use toggle to advance gear to 7 (or 5 if 6 speed). Transmission will shift into the appropriate gear and AFM will remain off until transmission moved to "D" or 8.

None here with 3,000 miles. 2017 Denali 4wd, 22s.
I'm in the market for a Yukon Denali and test drove one today. I have been in the position of asking for help from a car company after paying for their product. It sucks. Now I'm in the position of power. I was looking for the "buffeting" as I've read all the posts about it. And I found it in a 2017 new with 256 miles on it. It had 22's.
It happened at about 50-65, 65-80 was better. It does indeed sound like a window is open, but not as bad as when a window is open in my Jeep GC for example... It is annoying. The fact that my fist test drive I easily noticed it as did the salesman, makes me think this is not a rare issue. It is not a tire or wheel issue.. It is a DESIGN FLAW!
So I asked the salesman... No clue. Manager, no clue... So we asked the guy who orders the trucks for the dealership... He showed me the vent to the inside just inside of the rear door of a Cadillac SUV (not escalade) and said they all have a vent now because they are so air tight, if you don't have one, the HVAC would not be able to pump air into the car... Makes sense. Even more important, if an airbag goes off, not sure what the heck would happen. He said on the Yukon, the vent is huge..
This makes perfect sense to me, and it seems defeatable or fixable... The "buffeting" is basically a window open as a vent in the rear to let air in and out. I have always been dubious of the wheel and tire balance fix because 1) so many people say it works somewhat but not completely, and 2) buffeting is different than wheel wobble. This feels like air pressure, not shake or vibration...
In all my searching, I hadn't heard this theory. Maybe it's correct...
It makes me more likely to buy a Yukon because I know I can work with this... ("Great Stuff" anyone??)..
Man that 6.2 kicks it!
Here's an interesting archival tidbit...http://www.f150online.com/forums/2004-2008-f-150/371087-dont-touch-your-cabin-vents.html
