My 2013 express suddenly went it to anti theft mode while driving. Truck had to be towed to nearest dealer. We were 3 hours from home and towing my sons 3 quarter midget race cars. Dealer got reset code from factory and it wouldn't accept it. Ended p doing an entire reset of the system to reconfigure it. I pick it up tomorrow, I was wondering if anyone else has experienced a similar issue. My concern is ...is it fixed or is it going to shut down again at some point? What may have caused it?
