Help After Car Explosion: Support Needed

My car just randomly exploded while driving home on a 4.5-hour trip. I got 2 hours in, pulled into a gas station, and my car started smoking. Someone screamed at me to get out. I grabbed my dog and my cat, and we ran out. I had not even made it 5 feet from the car when it blew up. My insurance says they cannot do anything for me. They won’t cover a cent of the damages and loss.

Anything you could give would be so greatly appreciated.
