Starting in 2014, the vehicle had widely spaced and random issues of not starting, but would start fine after an undetermined amount of time. At the time, I did not know that it was related to the pass lock system which will not allow a restart for a period of approximately 10 minutes. In the past month, I have had this problem approximately 12 or more times and finally found out that it was caused by the pass lock system. This condition is very dangerous because if the truck is shut off to save fuel in a traffic jam, or at a traffic accident, etc, it may not restart when the road then becomes open, leaving you stranded in a traffic lane. Because the problem is totally intermittent, you can't troubleshoot it because by the time you try to find out what is wrong, there is nothing wrong and it will restart fine. The problem can be in the ignition module (icm), the body control module (bcm) or a connector or wiring at any point in between as well as some other remote possibilities. This problem has caused me to late almost every time it has happened. The only solution offered by the dealership is replacing parts piecemeal starting at the cheapest and working up which can lead to expenses over $1000. 00 and will still not guarantee the problem is fixed.
