I was driving on Interstate 64.im Norfolk when the car started to smoke, I just made to the side of the road and my car turned off. My dad told me that I he had the same thing happen to him on his 2011 optima his car turned off on the road. Kia had a recall on Kia optima engines. I spoke to another person that has a sol the same thing happened to them and there car only had 70,000 miles. Kia has put bad dangerous engines in there cars.
