“I was driving my mercedes E350 on I-95 north bound somewhere near philadelphia. My family including my wife and my two sons were also on the car. Somehow, all of sudden, the vehicle was not under control, which is, the vehicle quickly slowed down and despite the fact that I kept pressing the gas pedal, the vehicle did not move (I believe that the engine was shut down for some reason). I had to use hazard signals to warn the vehicles of the drivers behind me. Meanwhile, my son advised me to press the sos button of my vehicle. …”
