2005 Hyundai Sonata Speed Control & Cruise Problems

WHILE DRIVING ON THE FREEWAY THE CAR STARTED ACCELERATING ON ITS OWN. TRIED PUMPING THE GAS PEDAL TO RELEASE IT, CAR STILL ACCELERATED. BRAKES DID LITTLE GOOD. WAS ABLE TO DOWN SHIFT INTO FIRST GEAR, THEN INTO NEUTRAL AND UTILIZING THE EMERGENCY BRAKE WAS ABLE TO GET THE CAR SLOWED DOWN ENOUGH TO CUT THE ENGINE. SOME PROBLEM HAPPENED IMMEDIATELY WHEN I TURNED THE CAR BACK ON TRYING TO GET IT OFF THE FREEWAY OFF RAMP. WAS ABLE TO STOP SAFELY IN A PARKING LOT WITHOUT HITTING ANYTHING. HAD THE CAR TOWED TO THE DEALERSHIP, WHERE THEY SAID IT WAS A PROBLEM WITH THE THROTTLE. *TR
