“My 2005 toyota Scion TC turned off while I was driving. I put vehicle in park and re started it. Moments later the brakes failed and I turned into a plaza. At that point the steering failed. I did not know the vehicle was on fire until this point. I had no control of the car so I reached back and grabbed my two year old who was strapped in her car seat. Right before we jumped out the car stopped completely ( tires melted) , the flames were visible in front of me and the car filled with smoke. We jumped out and ran. Moments later the entire car was in flames. …”

This causes the car to overheat blow the engines. This is a safety issue as many people have had this happen in the middle of the road and at intersections where the car dies. …”
