I've been reading about the buffeting interior noise issue and people getting headaches in their Yukons/Tahoes/Escalades. Looks like the Bose ANC may be to blame. I'd like to ask the community.... is this really an issue with these vehicles? I've got a Yukon Denali on order and am becoming increasingly paranoid. I realize if this is a real big problem, I would hear more from the thousands of others who own these SUV's. I personally did not hear the problem on my test drive (though I never knew to look for it then).
