I JUST PICKED UP MY SON'S VEHICLE FROM THE SERVICE GARAGE WHERE I HAD JUST HAD NEW BRAKES AND ROTORS INSTALLED FOR HIM. I WAS ON THE WAY TO MEET MY HUSBAND AT THE GROCERY STORE BUT NEEDED TO DROP OFF SOME LETTERS AT THE OUTDOOR MAIL BOX AT THE POST OFFICE WHICH WAS < 1/4 MILE FROM THE SERVICE GARAGE. AS I PULLED UP TO THE POST OFFICE DROP BOX, I HAD MY FOOT ON THE BRAKE AND WAS GOING JUST A FEW MILES AN HOUR. ALL OF A SUDDEN THE ENGINE REVVED LOUDLY AND THE VEHICLE LURCHED FORWARD. I PUSHED HARDER ON THE BRAKE BUT IT WOULDN'T STOP! THANK GOD THERE WAS NO ONE IN FRONT OF ME OR IN THE PARKING LOT, SO I JUST STEERED THE VEHICLE AROUND THE LOT CONCENTRATING ON NOT HITTING ANYTHING! ALL THE WHILE TRYING TO BRAKE THE VEHICLE TO A STOP. IT TOOK ABOUT 10-15 SECONDS AND THE ENGINE FINALLY REVVED BACK DOWN (TO THE NORMAL SOUND) AND THE BRAKES WORKED AND I WAS ABLE TO STOP THE VEHICLE. I WAS ABLE TO DRIVE THE CAR TO THE GROCERY STORE WITHOUT ANOTHER INCIDENT. THIS HAS NEVER HAPPENED BEFORE (MY SON WAS GIVEN THE VEHICLE AT ABOUT 50,000 MILES) ACCORDING TO MY SON. IT WAS VERY FRIGHTENING-I AM SO GLAD NO ONE WAS IN FRONT OF ME. I JUST WANT SOME KIND OF RECORD OF THIS, IN CASE SOMETHING HAPPENS LATER. IS THERE ANY OTHER COMPLAINTS OF THIS? *TR
