general problems of the 2003 Dodge Grand Caravan

I purchased my Dodge Grand Caravan sport 2003 brand new off the lot in Nov. 2002. I kept it in mint condition with all maintenance logs filled out. At the time of incident there were only 95,000 miles on the van. It had never been in a wreck before. On Jan 18 2015 while driving in the mountains I hit black ice and lost control of the vehicle. It flipped front to back, did a 180 mid air, landed on wheels then rolled at least once to the left, landing on the wheels again. The airbags never deployed. My passenger and I both had our seatbelts on however I still lifted up and hit my head on the roof and the windshield. We are still assessing our injuries. I am extremely concerned as to how I lifted out of my seat, basically the seatbelt did not tighten to me. Also why didn't the airbags deploy? has there been a recall concerning the airbags or seat belts or other that I was never informed of?.
