Help! 4wd disengages

My 4wd disengaged 4 times in some pretty bad mud Saturday night. I got stuck 4 times and had to leave the truck Sat night. Got back in it Sunday morning and still no 4wd. Twice I was wenched 1 foot and the 4wd started working again. ABS, traction control, stabilitrak and brake warning lights were all on. All lights turned off after moving 1 foot. I was in 4 low which turns the traction control and stabilitrak off. I would get a message saying the 4wd was off. Any ideas on stopping the disengage?

Take it to the dealer.

I just got a call from my dealer with a recall on the 4x4 system. It has something to do with engage / disengage programming. That is probably your issue.
