Driving 70 mile in fwy my car engine just shut off completely I almost died out there because of cars behind me. I calmly changed steering wheel to right side of fwy with left over speed after 5 of vehicle behind me almost crashed me and each other. Turn off engine and started engine few time and it worked so I sent my car to shop and they said it's a 2 of sensor prob. And while he was moving my car, driver side seat switch button was on fire! fire! what is going on. I would have been killed out there if not for god. I see a lot of people complained on sensor prob with engine shut off, isn't this dangerous to drive???? risking all of people's lives????.
