I have a 2016 5.0 6 speed. Recently I had just put the truck in drive when I released it wouldn’t accelerate and a message reading “see manual” popped up on my dash. Turn the truck off. Back on worked as normal. I started to have cruise control randomly quit on me while high way driving. Then today I received a blink spot fault message on my dash then my dash began to “glitch” while driving down the highway it would light each of the “P R N D M 1 2” I’m afraid I felt it trying to actually attempt at switching to a few of those destinations while traveling at 55 mph. I took it straight to a dealership and they were not helpful in dissecting my experience. Any guesses? Any similar findings?
