Some vehicles do, for a fact, have problems but not all do, IMO. I read about and knew issues prior to purchasing so I drove and looked for what I had read about. I bought a 2016 GMC Yukon with 31K miles but prior to finding it, I drove a 2015 Tahoe with 55K miles that was almost flawless (wind noise by drivers window) but sold for more than I felt it was worth. I also drove a 2015 Tahoe that made me nauseated so bad that I couldn't finish the test drive and it affected me for hours after. When I found the Yukon, I drove it over varied road surfaces at all speeds. I've got an additional 1K miles on it and am very happy.
I believe the buffeting is true and wheel size and options like sunroof may exasperate the issues. I don't believe it occurs in all vehicles although some say it is in every vehicle just varies to the extent it is a problem. I didn't want a sunroof since they have only proven themselves problematic with our teenagers, glad I found a vehicle without one! I have 18" wheels on mine although I'd love to have 20 - it's not a deal killer. I went from an 03 Yukon XL to a Jeep and just pleased as punch to be back in my GMC. I am not concerned with noise from AFM - I came out of a Jeep Grand Cherokee Limited with Hemi engine - now THAT had MAJOR issues with AFM (my son's 4 cylinder Jetta could handle a highway incline better than my Jeep with Hemi!) and if you want POOR customer service, check out Chrysler. While I put a ton of miles on that vehicle, my warranty was worth gold - got used pretty much every oil change and Chrysler refused to address issues even when the mechanic and dealer could easily replicate. I did not experience 'booming' in any of the vehicles I drove.
