Question Asked: what would make my suburban go into 4 wheel drive on it's own?

On about three occasions my suburban went into auto 4 wheel drive on its own; however, I was able to go back to 2 wheel drive without a problem. Then one time it went into 4 wheel drive on its own, I could not get it out of 4 wheel drive until I shut the truck off. Could this be the control module for the 4 wheel drive?
