I was driving on the freeway at roughly 60-70mph when the car suddenly began decelerating and not responding when the acceleration was pressed. This has happened 3 times since I have been on the roads. Kia is unable to find error codes or diagnose the issue even after providing them with video evidence.there have been multiple "computer glitches" but this has been the most severe.
