I just got off work and got in my car to leave. I turned on the car and everything seemed normal. I pulled out of the parking lot and as soon as I pulled up to the light, which was 1block away, my car shut off. I was just at the red light waiting then my car turned off and would not turn back on. All the power in the car was there but my car would just not turn back on, my vehical was being operated in the automatic position. This was dangerous because it was a Friday afternoon during the 5 o'clock traffic and I had all these vehicals lined up behind me honking and I had to push my vehicals off to the side and call a tow truck. My vehical was luckily on the city street.
