I bought a used 2016 Yukon XL Denali with 7800 miles. Have had this problem since I bought it and the local dealer keeps giving me the run around. Finally I found the following bulletin on line from GM regarding the noise issue from the rear. The actual GM bulletin is: Document ID 4421703. #PIT5291B: Wind Whistle Noise At Highway Speeds From Left Or Right Rear Quarter Glass Area Here is a link. https://ww7.oemdtc.com/6731/wind-whistle-noise-at-highway-speeds-from-left-or-right-rear-quarter-glass-area-2015-2019-chevrolet-gmc NHTSA ID Number: 10160978 Manufacturer Communication Number: PIT5291E The local dealer said it would cost me an estimate of $550 to repair and maybe more. They allegedly have never heard of this complaint from anyone, though he confirmed the noise in a test drive with me when he sat in the back. I may have to address this on my own.
