Being new to this site, which appears to have a lot of resourceful, intelligent, and helpful users, I must say this particular thread is of concern to me. We just took delivery of a leftover '15 Yukon Denali at the end of the year. We've put on approx. 700+ miles. The only thing that I've noticed from the beginning is a, what I feel is a driveline vibe, most noticeable at highway speed (50-60 mph). Felt in steering wheel and seat. It's the same vibe felt when a u-joint is starting to fail, or an unbalanced driveshaft, but doesn't do it all the time. This is the best way that I can describe it. As for the cabin boom issue, thanks to this damn forum , I've noticed that slightly also. Nothing even close to what's being described by other users (yet). This is very disappointing to me. The amount of money that we pay for these vehicles IMO should equal a top quality product. Don't get me wrong, I'm realistic. I understand that all vehicles/manufacturers have their issues, but this too me, seems to be a major issue for GM, for whom I've been loyal for almost 30 years. That may change now. I just cringe at the thought of my new vehicle and other users' vehicles being used as "test" vehicles to "research" possible fixes. Disassembling of a vehicle interior is usually never a good idea unless you know a responsible, caring, dealership technician. All it does is cause more problems with panel fit, noise/rattles, dirt/grease marks. This is all UNACCEPTABLE. Did they not spend enough time on R & D? I'd hope that GM didn't release these vehicles knowing of these issues, gambling that only few would complain. Ok, that's enough venting for now. I'm going to hold off on my vibration issue until there is proof of a definite fix. I'll keep an eye on GM's bulletins and this forum, of course. I'm also going to remain hopeful and optimistic of GM's commitment to quality and customer satisfaction. Time will tell. Thank you for your time - Jack
