Side/window Air Bag problems of the 2001 Dodge Ram 2500

I was driving home when I ran into some bumpy roads and I looked at my passenger side airbag control module in the dash and it was gone. The whole inner dash was broke loose and plastic parts were falling onto the floorboard. I've e-mailed Dodge and haven't received anything back from them yet. The dealership says it could be from $1000 to $7000 to fix. It had a few cracks in it before but now it seams to be just falling to pieces. I believe this could cause my airbags to deploy at any minute and this is a safety issue. In an accident how could you tell if the airbag deployed before or after the incident? could the airbag cause an accident? Dodge says it's out of warranty and I will have to fix it myself. I think with all the dash issues, Dodge should at least bare some of the responsibility. They won't even tell me if my truck is safe to drive? so it sets in back yard.
