I leased a 2016 Yukon denali xl on 9/15/15. It has two major problems. 1. Buffeting/pressure noise - a noise as if a window is cracked, except it's not cracked. This occurs at speeds from 24mph and up and causes ears to pop and is noticeable to virtually every passenger I have had. 2. Whole-truck vibration - occurs between 70-80mph in entire vehicle. Wheel replacements, tire replacements, road-force balancing, driveshaft replacement, driveshaft "balancing", etc. . . . Nothing has fixed it. I have driven 13 2016 Yukon, Yukon xl, tahoe and suburbans. Every single one has the buffeting issues. All but one has the vibration issues. Gm has issued a pi stating that the roof bows may have come disconnected and they need to be reattached. The issue here is that reattaching them doesn't fix the buffeting issue. I have a date-stamped log of every dealer visit, conversation, email, etc. And am glad to share it. These issues are ridiculous to occur in any car much less a 75k flagship car that pulls in 3-7k in profit for gm/dealers per vehicle.
