This may be a bit long winded so please bear with me.

2015 RAM, Sunday morning I go to start the truck and the starter made about one revolution and stopped. I thought that was odd, but turned the key off and tried again and this time it started as normal. Now Monday morning I go to leave for work and notice as I'm driving the check engine light is on. I called the dealer when I got home and made an appointment for Thursday morning. While dropping the truck off the lady used her tablet on the OBDII port and said the truck had a powertrain software upgraded that was needed. Tech scanned the truck and performed the software upgrade, no other codes shown.

I checked the vehicle information center display and all the engine temps & oil pressure were fine, no messages shown either. Truck drive the same as always, so I had no signs that performance wise there was anything wrong.

Service lady said that apparently some of these trucks had an issue which I think she said was some sort of start fault requiring the ECM reflash.

My service ticket says "C 18 Flash Software 1 Software Flash for PCM".

Just below it is also says "Cause: F"

Just curious if anyone else had run into this situation?
