Driving at highway speed, the vehicle began to make a loud rattling noise that came from under the vehicle. A passerby pulled even with my car and began frantically gesturing. After a few seconds of confusion, me daughter said the she thought the man was saying "it's on fire." We pulled over to the shoulder of the road, exited quickly and realized there was fire visible in the engine area, seen through the grill. A good samaritan attempted to suppress the fire with an exstinguisher but moments later, it was fully engulfed.
The vehicle was not even 3.5 years old, it had been serviced in February 2023 and there was no warning before the fire began. The vehicle stopped accelerating and I immediately pulled over. The fire began as soon as I stopped the car and the vehicle was engulfed within minutes. My daughter and I were in the car. We barely escaped before the vehicle was on fire. I did not have a vehicle hitch on the vehicle and this was unrelated to the vehicle recall notice that I received several weeks after my incident.

The engine light consistently comes on and off. When you go to diagnose problem it would read- because the engine light would stay on. Two mechanics looked at it, and are saying it's a failing fuel pump. And it's not working correctly. The car just shut off and stopped working while exiting a busy freeway. Just cut off in the middle of the exit/road.
As I was driving down the street it sound like I ran over something but it was actually my engine failing, then caught on fire. I was able to pull over and used water bottles to let out the fire. My vehicle had to be towed to the repair shop because the engine wasn't able to restart.
