2023 Mazda MAZDA3

I was driving on the highway and decided to switch int the left lane so I sped up and heard a big bang and what sounded like my bumper being dragged against the ground. I see on my dashboard that there’s an electrical and engine malfunction so I pullover and pop the hood. A bunch of smoke comes out and i see a little fire so me and my friends run and call the police. The police and firefighters arrived just as the fire was getting large and it had engulfed the front right side of my car. If the notification that there was a malfunction didn’t come on, I feel as if we could’ve been hurt much worse or even have died. I’m not much of a person that knows about cars and it sounded like my bumper was scraping and by the amount of times i’ve scraped my bumper, i believed it until I saw my notification. The vehicle is still being inspected for cause of fire and this vehicle has never had this problem before.
