My son and I were driving home from work on IH-35 and I noticed smoke coming from under my hood. Then within seconds, flames appeared moving quickly towards the windshield. I attempted to move to the shoulder and after doing so, I was unable to stop since the brakes were no longer working. I had to use the parking brake when it slowed down and then once stopped, my son and I jumped out of the vehicle and within 3-5 seconds, the entire car was overcome with fire which then exploded.
