I have the same issue on my 2020 SLT. Get the service ESC, service parking brake, steering assist limited messages across the dash with the service engine light. Also get a cylinder 8 misfire code. Bought the truck 3 months ago problems started around 1500 miles going back to the shop for the 3rd time. First time they replaced the fuel injector on 8th cylinder. Second time pretty much replaced everything to do with the 8th cylinder while they had the engine opened up. Got the truck back and 3 days later same problem. Disappointing to have to bring a brand new truck back already. Been in the shop a total of 17 days so far. We will see what the next visit adds. Pretty sure I'm going to be pursuing lemon law soon.
