Warning Light On problems of the 2009 Dodge Avenger

I was driving down the highway and getting back to speed and heard a bang. Didn't hit anything and the driver's and passenger side airbags deployed. I was not injured and injured no-one else. My windshield on the passenger side was severly cracked. Now I'm between a rock and hard place, my insurance says that it may not be covered since I didn't collide with anyone, and I'm over my 36000 miles by 260 miles. Please if you have a Dodge Avenger do not ignore the airbag warning light, I could've killed numerous people that day and by some higher power did not.
