2020 FORD F-350 Forward Collision Avoidance Warnings Problems

Computer-dash info screens and drive modes. I am unable to change or check onboard dash info upon starting vehicle. Dash does not hold settings one day to the next. Unable to get into or change settings such as trailer settings-so can’t change braking effort-dangerous when hauling 20,000# trailer! Cannot put truck in tow mode or any other mode-defaults to slippery road mode. Again dangerous. Says hill start assist, hill descent assist and pre-collision assist is unavailable . This is all very potentially dangerous especially when hauling! Dealer cannot find problem. After truck is driven a while settings can be re-entered-truck has to be turned off first. Unable to load video of start up.

THE VEHICLE UPON STARTING WILL GIVE TWO WARNINGS: PRE COLLISION NOT AVAILABLE AND STEER ASSIST FAULT SERVICE REQUIRED. THIS DOES NOT HAPPEN ALL THE TIME I TURN VEHICLE OFF AND IT RESETS. I WILL NOT THIS MESSAGE FOR AWHILE AND THEN WILL OCCUR AGAIN I HAVE ALSO NOTICE THAT MY THROTTLE APPEARS TO RAISE ON ITS OWN WHILE DRIVING. THE TAIL GATE ALSO JUST OPENS ON ITS OWN.
