WE HAVE A 2004 HYUNDAI XG 350, ON AT LEAST A HALF A DOZEN OCCASIONS, WHILE COMING TO A STOP, THE CAR WOULD SUDDENLY ACCELERATE AND WOULD NOT STOP WHILE PRESSING ON THE BRAKE, LUCKILY WE WERE ABLE TO AVOID ANY ACCIDENTS. WE TOOK IT TO OUR LOCAL HYUNDAI DEALER ON 10/20/10, THEY TOLD US IT WAS THE THROTTLE POSITION SENSOR, THEY REPLACED IT, SAID IT WAS FIXED. YESTERDAY, 11/28/10, IT DID THE EXACT SAME THING AGAIN, ONLY THIS TIME WE WEREN'T AS LUCKY. MY HUSBAND TRIED TO STOP AS HE PULLED INTO OUR DRIVEWAY, THE CAR SUDDENLY ACCELERATED, AND HE RAN INTO THE FRONT OF OUR HOUSE. THE FRONT BUMPER OF THE CAR HAS MINIMAL DAMAGE, OUR HOUSE HAS A HUGE DENT IN THE FRONT OF IT. NEEDLESS TO SAY, IT COULD HAVE BEEN MUCH WORSE, HE WASN'T INJURED, BUT HE OR SOMEONE ELSE COULD HAVE BEEN. THE CAR IS CURRENTLY AT OUR LOCAL DEALERSHIP AGAIN, THEY CALLED TODAY AND SAID THEY COULDN'T FIND A PROBLEM WITH IT AND HYUNDAI SAYS THEY HAVE NO RECORD OF THIS PROBLEM ON THIS MODEL OF CAR, SO IMAGINE MY SURPRISE TO FIND SEVERAL COMPLAINTS ON THE NHTSA WEBSITE. SOMEONE IS COVERING UP THIS PROBLEM SOMEWHERE, I HOPE IT DOESN'T TAKE SOMEONE GETTING SERIOUSLY INJURED OR KILLED FOR SOMETHING TO BE DONE ABOUT IT. *TR
