There is an annoying an intermittent "Unknown Driver" flag that comes up on my display if I accidentally hit seat position settings on the door or it decides to act up. When this situation occurs it locks out all of the systems such gauge cluster, door locks, windows and etc.. Most of the time the truck won't start but it has done this while running and could not roll up the widows prior to an oncoming rain shower!! Good thing is that it decided to reset a few minutes after, other times I had to disconnect the battery. GM with their electrical problems. They make the best engines money can buy and are a on the cutting edge but they still haven't go a hold some of age old problems. I know things fail but it shouldn't be like this.
