This morning I remote started my truck and as I got closer it shut off. That's never happened. When I got in and started the truck it displayed multiple errors dealing with stability track, parking assist, ABS. I also noticed the gear indicator is not working. When I put it in gear (Allison 6 speed) it went into gear hard which it never does. I pulled away and it was in either 2nd or 3rd gear from a standstill, which has also never happened. When I stopped and put the truck in park it does not unlock the doors like it is supposed to do. Any ideas on what might be wrong? I've never had any problems at all with the truck until this. Any help is appreciated.
