I have 9000 miles on the truck and the issue has happened about 6 times. First time was within the first 400 miles. Last time was about 1 month ago. Had my 2021 GMC Sierra SLT 3.0 in the shop for about a week. Dealership had no knowledge of the issue and I supplied the service bulletin # for them. They dug all the way down to the "bent wheel" issue and visually inspected that it was not bent. So that was not the issue with my no start long crank problem. GM told them to put it back together and update the computer and give it back to me. It's been 1 week post "repair" and has not happened yet. Since it's intermittent I'm expecting it to happen again, but will probably be a while longer. I think at this point GM doesn't have a clue. I've reached out to other youtube people that reviewed these trucks/engines and had talked with the GM engineers in reviews past. The YouTube influencers are now saying that GM is keeping tight lips on this one! Just means they don't have a clue and they don't want the YouTube influencers jumping all over this.
