Hi:
When your vehicle says : unknown driver, instead of Driver 1 or driver 2, you have had your battery totally dead. so dead that all the programming was lost, the part about not staying started, or not going into gear is a bit baffling, unless your alternator is the real problem, and the battery has just enough charge to barely start your truck, and may need to be fully charged first and stay running . You will need to do remote and seat reprogramming, when you get this figured out

SOURCE: airbag light stay on 2003 chevy tahoe

The air bag light will remain illuminated if a fault has been detected in the air bag system.
The onboard computer will need to be interfaced with diagnostic equipment to read the fault.
This is also the only way to reset the light.
Good luck, I hope this helped.

SOURCE: power door locks on a 2004 chevy tahoe don't work

The door locks on my 1999 tahoe stopped working and I checked the fuse, which was fine. The problem turned out to be that the fuse for my cigarette lighter was bad and for some reason it also must be working in order for the door locks to work. Put in a new cigarette lighter fuse and the door locks worked again!
