Air Bag Not Deploy problems of the 2012 Chrysler Town & Country

I got into a car accident hit from side my car sustained over 5,000 of damage my children and I were in the car at the time the airbags did not deploy. I reported this to Chrysler they just advised me to go to dealer to have airbags checked. Never offered to do any further inquiry. Currently, my van starts at times and at others does not my new battery which was costly continues to be drained I called Chrysler they said it would cost 145. Just to diagnose the problem I don't have that kind of money available to check the car I said to the service dept. "you know these vans are experiencing these problems yet you still charge me so much to have a known problem checked?" they said yes do you want to make an apt. ? of course I did not.
