Quick background on my scenario, rented multiple 2015+ GM full size for work / family vacations and never experienced either. Bought a 16 Denali over labor day with an extensive test drive to eliminate any issues and so far so good. Yet I feel bad for folks who have to deal with the known issues. Swapping the Bridgestones for Goodyear and/or tire balance is one thing. But shooting in the dark on everything else would drive me nuts, esp if the dealer was giving me the run around. But it sounds like there are as many stand up dealers as those looking to pass the buck.
My background is high tech and when something of this magnitude presents itself all hands are called to deck to root cause the issue. And nothing stops until it's done. How can it be that GM has not nailed this? Or have they and are avoiding the worst case scenario of buy backs? Are the buffeting and vibration issues less from 2015 to 2016? And gone by 2017? And is there an idea on % of owners having the issue? Only reason I bring all of the above up is I'm confused that in this day and age it's still an ongoing issue for GM and their full size SUVs which drives most of their profit.
