Air Bag On-off Switch problems of the 2001 Chevrolet Impala

I was driving on the freeway in traffic and I switch lane to carpool lane. As I was picking up speed when I was rear ended from behind pushed down forward further and my car turned and slammed onto the center divider lane. After my car struck center divider lane same car who hit me has not slowed down and hit me again on high impact behind driver side passenger door and gas tank smashing onto my rear wheel. None of the air bags deployed in my car. I am 5'1 in height and weight about 133lb. We bounced around as well as my backseat passenger who is my daughter who was seating in a booster seat and we were both wearing seat-belts. When the car hit us sideways and jerked us around my head slammed by the door panel and busted my head open which caused it to bleed badly. Believe it was the initial impact from the rear my keys flew out of the ignition and on to the floor in the backseat floor firefighter had to search because I told them as soon as they showed up "my car is still running I don't know where the keys are at!" the ignition was still in on position as if the key was in it. My doors on driver side and behind driver side was smashed and my car shifted out of its alignment that even my daughter who was in the rear seat behind the front passenger side of my car her door could not be opened by the fire department. We were both removed from the front passenger side door and ambulance transported us to hospital. My daughter who is 10 years of age was shaken up sick to her stomach dizzy with minor bruises. I suffer bruises on top of my foot. Bruises on my thigh my legs bounced up and hit the stirring wheel. Bruises on both my arms and my draughts arms and elbow! we are both tender and soar all over the bodies but, praise god we are alive! by the way my car is totaled and its paid for. Pls give advice on this situation.

Security light comes on, traction light comes on, rpm's drop to 0, gas drops to 0, constant draining of battery and is dead after 10 or so hours. Many people on forums are all complaining of the same thing and even mechanics say that this is a very common problem with these cars yet there is no recall! I have spent as of now 1000 dollars on this problem and my dealer is telling me that might not fix the problem completely!!! I have put in a new alternator, new battery, new bcm, and now a new ignition switch! I currently have the old bcm and the new one is in my car.

Consumer stated that while driving down the road lost power, all of the dashboard lights were gone. Electrical systems failed on the dashboard, but no where else. He was still able to roll the electrical windows up and down, and radio still came on. Also, airbag light came on, indicating there was a problem. Sometimes when this happened air conditioner did not work. This happened 3 times in the last 2 months. Consumer had taken vehicle to dealer/mechanic, and was told to disconnect the battery. This happened to reset the computer. But when this happened a second time , he took vehicle back to dealer/mechanic. They put vehicle on the computer, and could not find anything wrong with it, but yet they changed the ignition switch, which they said could be bad.
