When the truck is turned off it sometimes can take anywhere from 2 minutes to over 1 hour to restart. When this issue occurs and the key is turned to start the vehicle all you will hear is a "click" sound coming from what I assume is the starter. While not starting, everything else electrical in the vehicle seems to be working fine. Although this truck was delivered new in December of 2017(build date of 8/17), it was not put on the road and in service(built out as a tow truck) until mid may of 2018. Although this starting issue did not begin with my truck until sometime in February/March 2019, we have another truck that is the exact same model (build date of 2/18) that has been experiencing the same issue for about 7 months now. That second truck was finally taken to the dealer and they could not find a specific problem so they replaced the started. The problem still exists. The driver recently replaced the battery just to try to eliminate the potential cause of this issue but that yielded no positive results either. We are at a loss and this issue is literally costing us money!! in general, this non-starting issue happens a couple times a week.
