2008 Kia Sportage Cruise Control Problems

While driving on the highway with cruise control set at 65 mph, your car unexpectedly accelerated on its own. Pressing the brake and turning off cruise control only temporarily slowed it down — once you released the brake, it accelerated again. Even after stopping the vehicle completely and putting it in Park, the engine raced to full throttle by itself. After restarting the engine, it behaved normally for about 10 minutes, but then the problem returned with unintended acceleration occurring again. This issue likely involves a malfunction in the cruise control system or engine throttle control that needs professional diagnosis and repair.
