Ford Focus burnt out

I bought a 2016 Ford Focus eco boost hatch back automatic on the 26 Jun 2023 second hand. On the 7th of December 2023 I experienced the my worst nightmare. After I done 12hr shift I drove from work to home. And inside the car no alarms showed of any problems. When I arrived at home I parked my car in front of my garage, got out and went into my home, then I realized I forgot my work bag in the car. As I went out to get my bag my car was flames, literally on flames, the car automatically caught fire. I notified the fire brigade to assist. I lost my car.
