I was stopped at an intersection at a traffic light & when the light turned green, i turned left & i'm uncertain if my emergency brakes kicked on or if my car simply stalled out, but my car suddenly would not move. my purse, in the passenger seat flew forward & hit the floor of the vehicle. the car behind me at the light nearly rear ended me, but fortunately did not. we brought the vehicle to jim ellis buick to be serviced, but they said it appeared fine & was confused. i definitely was not in any danger of hitting anything when turning at the intersection. this incident has made me uneasy when operating my car.
