While driving down the road, my dash just randomly shuts off, my doors re-lock and my stabilitrak turns off. I don't lose any power but I have noticed that it's more sluggish when accelerating than usual and the transmission is slamming into gears randomly as it never has before. Does anyone know what it could be? Any information would be helpful!

How old is the vehicle battery?
Have you checked and cleaned battery connections?
