While I was driving on the highway in the left lane, smoke came from the engine, then it started coming from underneath the car. The car turned off. I was forced to stop on the left lane of the highway and exit the vehicle and walk as far away as possible. I called 911, then I noticed fire coming from the engine. This was unsafe for myself as well as other riders on the highway. Firefighters came and put out the fire. Once they left, I was left by myself waiting for the tow truck to arrive. No police officers helped to keep myself safe while waiting on the left shoulder once the highway re-opened. When asked if I needed a police report, the police officer said no because it wasn't a crash. The vehicle was inspected by my insurance company and it was deemed a total loss. There were no warning signs or messages or symptoms prior to the failure at all.
