Stop buying any 2015 and 2016 Yukon,Suburbans and Tahoes. If you already did purchase one then give it back, too many problems and there is no fix that Gm can offer especially with the wind noise in the cabin that is annoying and hurting my ears and major booming and vibration feelings. I have a 2015 Yukon XL SLT purchased at $85,000 on the road, not even worth that price. All of the parts on these new model SUV's are cheap quality exterior parts and will eventually start falling off like mine at 25,000km.Stay away from these 2015 and 2016 models untill GM solves the issues.
