Open the full vehicle complaint log (all categories)Several times the car has accelerated without me pushing on the gas pedal. Kia has been unable to find a problem.
THE SPEED CONTROL BRAKES WERE TRIGGERED BY A LOADED BNSF CONTAINER TRAIN ABOUT 50 YARDS TO THE LEFT OF AND PARRALELLING THE VEHICLE. THERE WAS NO TRAFFIC AHEAD OF OR BEHIND OUR CAR AS WE CAUGHT UP WITH THIS TRAIN AND THEN THERE WERE RAPID BEEPS FROM THE DASH AREA AND THE BRAKES WERE FIRMLY APPLIED AS THEY WOULD BE IF WE WERE APPROACHING A SLOWED VEHICLE ON THE ROAD. THIS REPEATED UNTIL I TURNED OFF THE CRUISE CONTROL. THE TRAIN LATER GOT AHEAD OF US AND WHEN WE CAUGHT UP WITH IT THE PROCESS REPEATED. NO OTHER TRAIN HAD THIS EFFECT NOT HAS THE PROBLEM RECURED. THIS WAS ON US 84 BETWEEN TEXICO AND MULESHOE, TX.
CRUISE CONTROL DOES NOT WORK, DEALERSHIP SAID KIA IS AWARE OF THE PROBLEM BUT HAS NOT FIXED IT. *TR
