I sold my 2015i (2015.5) Yukon XL Denali on Friday Feb 20, 2015. I picked it up on December 22, 2014 (Oct 18 build date). Several dealers could not solve a high pitched noise / whistle coming from the right front passenger side of the vehicle. They also couldn't get the right front passenger door from rattling when the stereo was at medium to high volume.
Took a bath on the vehicle. Glad it is gone. Unlikely to buy another GM product -- this was my 6th Tahoe/Yukon in 14 years.
