When pulling into a parking spot and with my foot on the break, the car suddenly accelerated. The car did not react to my breaking. The car kept moving forward over a sidewalk, over the curb on the street, into the back end of a pickup parked on the road I was facing, and started heading across the street toward another parked truck. Luckily there was no one on the sidewalk, no one was hurt. This has not happened before or since. No warning signs. When I took the car in to get an alternator replaced, the initial shop said they could not fix it bacause of codes that came up concerning the electrical system. I then had the car towed to a Kia dealer. They fixed the alternator but never mentioned the other codes. Suspecious.
