I have a 2007 Yukon Denali with 187K miles and have the same noise as the you tube video. Usually occurs at 1800 rpm around 70-75 mph. I have taken to dealer for test drive so they could hear it twice and it did not create the sound. both times it was a rainy day. Anyone notice this either their issue? Reading these posts definitely seems like a systemic issue. hope somebody has figured it out.
