Forgot to mention, once this happens both times I have had to be drug out and shut the truck off, keys out, and let it sit for ten or so minutes before there is any function to the 4WD dial. Light goes out on the dial, and the truck shows it’s in 4WD^ on the offroad page but no power to the front wheels. Had I been alone I’d be writing off a truck and absolutely shafted.

Not to bring an apparently dead topic back into relevancy, but just had this same thing happen to me wheeling with some friends. 2015 Sierra SLE All Terrain. Pulled into a creek in 4Lo, sank into the silt and gave it consistent gas to pull my way through, started to slow and gave more gas to increase speed and on the up-rev got the “4WD OFF” message and bogged down in water midway up my doors? Jeep and 4Runner in front of me had to pull my heavy ass out and got through it no problem. Had to lean it down hill to get all the water to run out of the floor pans. This has happened before in the same situation while in mud in 4Lo and gave gas to keep moving and “4WD OFF” message and got bogged. Anybody know why this happens and if there’s an override?
