RPM's revved as high as can be in park, reverse or randomly when driving. Took the car in for repair, accelerator pedal and sensor assembly was replaced. 4 days later car accelerated again on its own. Had to steer car into concrete barrier to slow down car. Injuries from accident. Towed car to Kia dealership. They report that the problem cannot be duplicated and car is safe to drive. Again, this acceleration issue happens at random times.
