I am going to address some forensic fire evaluations I have been involved in. You should find them interesting because no matter how you slice it, the conclusions are beyond question.
There are structure fires, forest fires and car fires. No, a fire is not just a fire! Vehicle fires are by themselves.
Facts surrounding the fire: Fire self suppressed because it was covered with a heavy car cover (thick insulated blanket). Engine started and fuel filler door button accidently pushed. It is possible that because cover was on vehicle there was too much resistance in the filler door opening, but no matter what it illustrated a dangerous design issue. In the left rear quarter were two foam insulator bags wrapped in polyethylene (extremely flammable) plastic bags. All this designed on a poly carbon Corvette body. Fuel filler door made of steel. Wiring and opening actuator mounted directly above the insulator/ sound deadener bags.
The fire marshall that examined the fire could not reach a conclusion.
The origin of this fire was at the filler door area. Flames were venting from this area melting the 1/4 panel in the area.
Research on consumer complaints turned up complaints of filler door sticking and binding through auto service bulletins.
Service manual cited extreme warnings of heat or direct flame being anywhere near the foam bags.
