Have about 6000 miles on my 2019 GMC seirra denali 5.3. I've been experiencing a very troubling issue been to the dealership once already and had a hard time convincing them that something was wrong with the truck.every time I drive for long periods of time or idle for 10+ mins when I shift from park to drive I cannot go faster than 5 mph without the rear brakes locking up. I do not know if this is some kind of limp mode or what.
