I have a 2019 GMC Sierra 1500, with all of the same issues, it started when the truck had approx. 1500 km it, now it has 39,000 km and the issue is ongoing with no resolution in sight. This truck has had 4 recalls on it and the transfer case was one of them, still happening almost every time I use 4 wheel drive. I feel your pain I live in Northern Alberta Canada and there is a reason I bought a truck with 4 wheel drive, because I want/need to use it.
