1998 Dodge Dakota seat belts problems

Me and a friend were in a car accident .when we lost control of my 1998 dodge dakota and hit the side of a building at 40-45 MPH when we hit the air bags did not deploy and the seat belts did not lock up like they were supposed to in result we bounced or faces and heads off of the steering wheel and dash board and now having head neck and back problems.

I have had numerous problems with my 1998 dodge dakota. I purchased it brand new. 2 months after 8/98 purchase date, the transmission went out. The brakes have had to be replaced several times, the map sensor went out while driving down the highway causing the vehicle to shut down. I recently had to replace the lower ball joints. The seat belts come off entirely too easy. All of this and the vehicle only has 39,000 miles on it. I sent arbitration papers to chrysler twice with no response.
