Hey Everyone, was just searching around for this same problem and came upon this thread. I have a brand new 2020 Chevy 2500 Gas (had 80 miles on it when i got it). Steering didn't really fee correct from the beginning. I have had a 2016 Denali 1500, 2018 SLT 1500 and never experienced this before. So I took it in for steering wheel shake and what seemed to be an alignment issue on Nov 19th . They did the alignment, but it didn't really help all that much- seemed better but not much. When driving down the highway at 65 plus, the steering feels loose and sometime cocks the wheel left or right 1-2 degrees. I also notice the clunking when at low speeds when pulling out of my driveway and it only happens in the morning when its cold and at less that 15 mph. When doing a search I ran across this bulletin as well. So wondering if its related or not. Its an official service bulletin from GM so i would suspect they are starting to investigate it. Hopefully they do something fast. Im not into buying expensive trucks that should work properly right out of the gate. At the price point, the damn thing should be just about flawless.
