Started up truck to warm up after about 3 minutes heard bang and both front airbags had deployed for no reason. Prior to this had issue with intermittent dash board lights (battery, speed odometer, seatbelt and airbag lights) being on. GM refuses to cover because I did not take to "dealer". I took it to my local mechanic instead who could find no issue other than corroded grounds. Currently it is being repaired by my insurance company.

I was driving a Chevy Trailblazer rented from hertz on December 29, 2004. On highway 285 near mile marker 189.5, I encountered black ice on a curve. The vehicle started a 4-wheel drift into the oncoming lane. I attempted to avoid colliding with another vehicle that had spun out. The ABS did not work. There was no stability control. I struck an embankment and the vehicle flipped over. Although there was both frontal and side impact, no airbags deployed. It is my belief that the Chevy Trailblazer is inherently unsafe. There is no way this vehicle should have rolled over at the speed at which I was driving.
