I was driving my 2012 hyundia Sonata down the road, and all of a sudden, the whole car shut off. This caused the steering wheel and the brakes to fail. Fortunately, I was able to make it to the side of the road, and I smelled smoke. At first, I thought the engine was overheating, so I opened the hood to see what was going on. I saw a ball of fire, and quickly grabbed my 4 year old and 10 year old out of the car. By the time I got them out of the car, the whole engine bay engulfed in flames. After telling my story, I have had multiple people reach out to me with similar stories.
