2008 Chrysler Town And Country body & structure problems

My wife was stopped on the I-94 freeway in detroit, mi. A vehicle was closing in behind her at a high rate of speed, and crashed into the rear end of the vehicle. Her vehicle then lunged forward and hit the vehicle in front of her. The front and rear of the vehicle experienced significant damage, yet none of the airbags in the vehicle deployed. My wife's head contacted the steering wheel. She was transported by ambulance to the hospital for evaluation.

After 6 weeks of owning the vehicle I noticed that the sliding doors were not operating correctly. They would open or close on their own. It started off being only once or twice a month to now an almost everyday occurrence. I have taken it back to the dealership and they sent it to another dealership and I am being told "they can't get it to duplicate" well al I can say is what is it going to take for them to fix the problem, a child getting badly hurt or killed.
