While driving my grandbaby home I was unable to avoid hitting a deer when it ran into the road. Neither the automatic braking nor the airbags deployed when I hit the deer at the front left side. It destroyed the headlight and damaged the fender and quarterpanel lightly and slightly bent the hood. I was able to pull over safely. When I got out to look at the damage, I could not open the hood but I could see a small flame on the passsenger side of the engine (this would be on the other side of the engine from where I hit the deer.) I grabbed a fire extinguisher from the back of my car but could not get the fire out. I got my grandbaby out safely at that point. Another driver stopped and tried to get the fire out with his fire extinguisher but to no avail. We called 911 and the fire department promptly got there. By then the entire car was in flames. The fire dept put out the car and nearby weeds that were burning. Besides the safety equipment not working, what concerns me most is that a minor accident caused the entire car to become engulfed in flames within 3-4 minutes. I had enough time to get myself and my grandson out but not his carseat base or diaperbag. The car was burnt down to the frame.
