I’ve had three of these in a week. Truck will
Only go 15-20 mph. Brought to the Ford dealership each time. They’ve reset and can’t identify what the issue is.
I had the same thing happen. No power and one of the cylinders was off line. Found out that the new Ford vehicles receive automatic updates, if you interrupt the update, strange things can happen. I took mine directly to the dealer and they finished the update and all has been good. Have since programmed the vehicle to only update the system on Sundays at 1 AM. 2021 F150 XLT Leadfoot.
