    After driving a few hours in tow/ haul and then restarting( after turning off engine) the tow function will not work. If I let the truck sit for a few hours and then the tow will work, any comments, besides not stopping, Henry.

    That's pretty much going to be a GM dealer service thing. They would need to check with their scan tool if the computer modules associated with this are malfunctioning.
