“My car turned off while I was driving and almost caused me to crash into an 18 wheeler. Thank God I turned on my emergency signal and the truck swerved!. I would of died. I was stuck in the middle of the road and luckily some passersby helped me push it into a commercial parking area. I tried to start it again and it wouldn't start. But, when I turn my key into the off position, my car tried starting by itself. It was scary. It was checked by a mechanic, prior to this happening, because the car was hard to start. The mechanic told me to find out if there is a recall. However, I did some research and there was a recall on the ignition switch and fuel pump. The ignition switch was faulty causing the car to turn off while moving and two people died as a result. I entered the VIN # and it didn't show any recalls.”
