Over the past 10 years my wife and I have purchased a new Fully Loaded 4x4 Denali every 2 years... until now. We have had 1500s, 2500 HD L5P, and most recent a Yukon. After the lack of response and crappy service from GM (not the dealership) following a blatantly obvious noise/pressure issue, we were fed up. A vehicle is not supposed to hurt your ears and give you headaches and the manufacturer keep saying “it is functioning as designed” BS!!
For the high cost of the new GM SUVs, we instead went with a 6 seater (3 rows of bucket seat option) 2020 Mercedes GLS580. Our 2012 E550 AMG Cabriolet (same engine) has been great for 80k miles and the GLS is longer than the K2 Yukon but Shorter than the 2021 Yukon. It rides SO much smoother, tighter, and quieter and with more tech and better build quality and materials, all with Mercedes 7 year 100k mile warranty (if we keep it that long). Been with GM since 1990 (RC Sierra GT Stepside) and still have the Sierra AT4 and 2007 Sierra 1500 SWB RC though...for now.
