Problems With 4wd Controller

About a year ago my truck was stuck in 4WD Hi and wouldn't go back to 2WD. I took it to the dealer and they said there was a TSB for the controller and they re-programed it. Since then I have had an intermitten problem with it starting in 4WD when I start it up in my driveway. I didn't have it in 4WD when I parked it. I do know that colder weather makes it happen more often but I have yet to replicate the problem at the dealer. I was wondering if anyone else had this problem and if it might be an indication that I need a new control unit. It doesn't give me any problems switching in and out of 4WD so it seems to work properly I just don't want to be stuck somewhere and not be able to get it out of 4WD Lo someday.

Your push-button controls may be going out...Do the lights blink when any mode is active? I know there's some built in protection that if the 4wd controls start malfunctioning the truck will default to 4hi.
