So today I got in my truck tried to turn on Tow/Haul mode and it wouldn't work. Tried the traction control and the exhaust brake and the same thing. I had to restart my truck three times before they started working again. Has anyone else had this issue. Also if you have had the issue what was the fix. Also talked to the dealer and they acted like I was making it up. I'm beginning to regret getting rid of my old 12 valve it was simple.
