2014 Jeep Cherokee air bags problems

My daughter was stopped at a traffic light and a car hit the truck behind her and pushed it into her and pushed her into the car in front of her. She seen the car coming and not stopping so she hit the brakes hard, so she didn't hit the car in front of her hard. The air bags didn't deploy and she hit her head and sustained a very bad concussion and lost the hearing in her left ear. She hit her head so hard it has a white matter spot on her brain.

Backed out of driveway then warning light/symbol and tone came on that the 4 wheel drive system was unavailable and service required, service airbag warning came on as well as service parking brake, limped back into driveway barely. Turned vehicle off restarted still getting warnings and tried to move vehicle motor revved but vehicle didn't move forward or reverse. Got another warning to put vehicle into park then select gear. Currently waiting for tow truck. Jeep won't move in drive or reverse now.
