2008 Kia Sorento vehicle speed control problems

“Even after having the ESC and relay box replaced the vehicle has become much worse. It's shuts down my accelerator pedal and won't move I have to shut it off completely for it to reset its extremely unsafe and is now affecting my job. And the ability to take car of my son. And Kia wants to charge me $200 plus for a diagnosis when it clearly keeps shutting down the vehicle and the esc off light is on. I even replaced the accelerator pedal assembly $180 and it did not fix the problem please help. Also this has been an on going issue since August 2020 and even after running diagnostic on it. I keep getting the run around from everyone stating a different issue each time.”

“WHEN IT'S HUMID OUTSIDE OR THERE IS ANY KIND OF MOISTURE IN THE AIR MY CHECK ENGINE LIGHT COMES ON ALONG WITH THE ESC LIGHT. THE CAR SEEMS BOGGED DOWN AND WONT GO ABOVE 2000 RPM. IT TAKES 15 MINUTES JUST TO GET THE CAR UP TO 50 MPH AND THATS WITH THE GAS PEDDLE PUSHED ALL THE WAY TO THE FLOOR. IT DOES IT MAINLY WHEN I'M DRIVING ON THE HIGHWAY WHICH IS SCARY. IT LOOSES MOST OF ITS ACCELERATION POWER”

“AFTER STOPPING AND LOOKING FOR ONCOMING CARS AND STARTING AGAIN, THE CAR JETTISONED CAUSING ME TO HIT ANOTHER CAR AND THE CAR WOULDN'T STOP FOR ABOUT A HALF BLOCK.”

“WHEN DRIVING UP HILL AT 35 MPH IN AUTOMATIC DRIVE OUR VEHICLE LOSES POWER. WHEN PUSHING DOWN ON GAS PEDAL, IT DOES NOT RESPOND. WE TOOK IT TO A LOCAL MECHANIC WHO TEST DROVE IT AND EXPERIENCED SAME PROBLEM. WHEN USING MANUAL SHIFT THE CAR DOE NOT LOSE POWER AND RESPONDS WHEN GOING UP HILL. WE WERE TOLD IT GOES FROM FIRST GEAR TO FIFTH GEAR IN ABOUT 500 FEET WHEN IN AUTOMATIC DRIVE. LOCAL MECHANIC CALLED KIA DEALS IN SPOKANE AND I WENT TO EDMARK KIA IN NAMPA EACH DEALERSHIP CLAIMS TO KNOW NOTHING ABOUT THIS PROBLEM. ESC LIGHT IS ALSO ON.”
