I was driving with my cruise control set at 70 mph, on Highway 95 ( the speed limit ) While driving my vehicle suddenly dropped to 40 mph, all dashboard lights began to flash. I had problems with the steering as I attempted to pull over. I had a tractor trailer behind me on a major highway. When I came to a complete stop, my engine light kept flashing. I drove my car to the KIA dealership in GA, where they determined my engine failed ( software issues ) There were no prior warnings. My vehicle had been serviced just a few weeks prior. KIA is fully aware of these ongoing engine failures according to my local KIA dealer rep.
