I believe CR.... I had a 2015 Yukon Denali... The Transmission failed/replaced 2x. Fuel rail system replaced, steering column 2x, 2 valves bent, and after repair burnning oil. Finally GM bought it back for 69k but I had it for 4 years and about 75k miles on it. Strange as it sound I loved my Yukon!
Got the 69K check and bought a fully loaded 2020 2500HD Duramax Denali. Yesterday I notice oil in my drive way! LOL LOL . My first diesel and I love it.
Just placed an order for 2022 Yukon Denali and now debating to order it with the duramax or not. Hummm..
