2005 Chevrolet Trailblazer engine problems

I was involved in an automobile crash in my 2005 chevy trailblazer. Upon impact, the car ignited under the hood and flames came up on the outside of the windshield while my family was still in the car. Fortunately I was able to get my family out of the car before it was totally engulfed in flames and destroyed by fire. I contacted GM and asked why my car burned. I told them I was concerned about the safety of my family since members of my extended family own similar GM suvs.

I bought my 2005 trailblazer the same year with 19+k miles. I started having it stall on me around 30k miles. I took it to hayward, ca chevy dealership because it was still under warranty. They said that they found nothing. I took in again because the engine light came up and they said the problem was the light only but, that's the light that would flash when it stalls. I took the car back in several times for the same situation.
