upon starting the vehicle, , immediately get a “reduced power warning” message on the dash and the truck was idling roughly and no power on steppping on the gas, nothing. Started stopped 6 times no change. Finally pulled some fuses including a 50amp off passenger side fuse panel and it cleared it, drove home with check engine light on. Pull power to the battery and it cleared the light. Anyone experience this? Or just lucky me.
Prior to this, had power windows issues and vehicle collision alert went off last software update might have remedied windows, not sure yet

Yeah there are some other reports like this. Some have software issues, while other have hard parts failing like the fuel pump control module. Best to get it to the dealer for proper diagnosis and service with significant issue.
