I just bought a 2017 Ecodiesel. It has 19k miles on it. Yesterday after letting it idle for a bit while I was in a store, my check engine light came on as I drove away. I turned around and went back and asked them to scan the code. It came up Service Shifter and Service Trailer Brake System. I was about an hour and a half from home. Drove all the way home with no issues with the truck. Check engine light stayed on -- did not blink. Am going to call a dealership tomorrow. In the meantime, has anyone else experienced this?
