My 2015 Yukon XL I ordered should be in next week. After reading this, I will be taking it on an extensive test drive before I sign any papers. The only thing that worries me is some people are experiencing it after a few weeks of ownership. During my test drive I want to do my best to try and hear the noise if it is present. In order to have the highest probability of replicating the sound, I should drive around 40 mph and what else, windows up or down, ac on or off, radio on or off?
I ordered a SLT with 18" wheels, max trailering package, navi, and cross bars.
Thanks
