I was driving down the road and all of the sudden it was if my transmission disengaged and my car lost power. It then automatically came back on and the �service stabilitrak� lights came on. I nearly avoided an accident and was able to pull off onto the side of the road.

On two separate occasions my truck has acted like it is in neutral while driving. The drive system disengages and the engine just revs. Once this happened while driving down the road, the other when the truck was stuck in snow. When it was stuck it disabled the 4wd system completely, rendering the vehicle stranded.
