2018 Hyundai Accent Electrical System

My 2018 Hyundai Accent caught fire in motion on the way to get gas on June 21, 2021. The car had no recalls and no electrical issues prior to the explosion. Fire department ruled the accident as electrical, I had the vehicle for 6 months. A loud explosion sound came from the hood, it started smoking and we pulled the car off the road, moments later it caught fire and created an explosion spreading from the hood to the back of the car. Because i dont have a car, I had temporarily close my small online business, this has been a nightmare.

I'VE HAD MY CAR FOR LESS THAN 2 YEARS AND THE BATTERY COMPLETELY DRAINED/DEAD. HYUNDAI REFUSES TO COVER IT UNDER THE 3 YEAR WARRANTY DUE TO MY CAR HAVING OVER 36K MILES. THE CAR WAS BRAND NEW WHEN I PURCHASED IT AND I'VE NEVER HAD A CAR BATTERY DIED SO FAST EVER IN MY LIFE. ALSO, SOMETIMES THE BACKUP CAMERA WON'T TURN OFF AND WILL STAY ON EVEN AFTER DRIVING FROND FOR MORE THAN 10 MINUTES. IT WILL ONLY TURN BACK OFF IF I TURN THE CAR COMPLETELY OFF AND THEN BACK ON AGAIN.
