you have a failing body control module. you can try to reboot it by taking off a battery cable and installing it to see if anything comes back. if not, you need a shop to verify, replace and flash for you.

i usually disconnect the battery and it will undo everything but once i start the car it will go back into service vehicle soon key fob battery low rear parking lamp out but all the things it says is wrong are workin fine.
