When driving straight along an interstate with my cruise control set to the speed limit, a loud bang came from under the hood of my kia, the check engine indicator turned on, and smoke began to pour out from under the hood and inside my car through the air vents. when i pushed the gas pedal gently, there was a low guttural noise and my car was not picking up speed. i put my car into neutral and coasted to the shoulder with low visibility as the smoke became more dense and darker in color. i brought my vehicle to a full stop on the shoulder and put it into park before turning it off and removing my key from the ignition. upon exiting the car i noticed the smoke was even more intense than before and promptly called 911 and gave my location and situation information to the 911 representative. as i was speaking, i narrated in horror as flames became visible from under the car itself and under the hood as well, in as little as one minute after exiting my car. by the time the fire department got to the vehicle, the flames were over 20 feet tall and the heat was unbearable; i relocated myself farther and farther away to stay cool and safe as the time went on. nobody was burned, hurt, or injured as a result of the incident, but only my mere coincidence.
