Yeah I'm a bit stumped as well. When the conditions were "normal" it was all the time...now more sporadic. I'm still thinking it's related to the vents or to a lesser extent,the air conditioning.

Hey everyone, First time poster and I found this forum because I was searching this exact topic. On Monday I brought my Yukon Denali to the dealership for this same pressure sensation that so many of you have described. The dealership told me that whatever I was experiencing was just me and thus extremely isolated. My comment back before storming out was that I didn't care if it was just me as it was still happening to me. The one thing I keep thinking about as the reason for this happening is that it must relate to the cause of buffeting in the first place...which is a loss or escape of pressure. As a result I'm convinced it must have something to do with the Vents in the vehicle. I don't know how many there are or where they're located, but just a thought. Would one of you be willing to drive at the speed that creates the pressure and then hit the button that closes the vents (recirculate button) to see if anything changes? I'm in Canada and with the recent snow fall im having trouble replicating the sound.
