ON MONDAY JULY 29,2013 WHILE I WAS SET ON 70 MPH CRUISE CONTROL, MY TOYOTA COROLLA SUDDENLY SURGED FORWARD. I HAVE NO IDEA HOW FAST IT MADE THE CAR GO ,BUT I HAVE NEVER BEEN IN ANYTHING GOING THAT FAST. I HAD TO TAKE THE CAR INTO THE GRASS MEDIAN TO AVOID HITTING ANOTHER CAR WHEN THE BRAKES WOULD NOT STOP MY CAR. WE STILL FLEW DOWN THE GRASS MEDIAN LIKE A SPEED BOAT HITTING WAVES, WE WERE BOUNCING, THE CAR WAS BOUNCING, I HAD SEVERE CRAMPS AND STABBING ACROSS MY LOWER KIDNEY AREA WHEN WE FINALLY CAME TO A STOP. I HAD TO HOLD THE BRAKE PEDAL TO THE FLOOR FOR WHAT SEEMED LIKE ETERNITY. BEFORE IT FINALLY STOPPED. I REPORTED THE INCIDENT IN GREAT DETAIL TO TOYOTA CORPORATE AND MY CASE WAS #1307291802.(THIS CASE # IS NO LONGER VALID) I WAS TOLD AT THAT TIME IF I FELT SAFE, I COULD TAKE IT TO MY DEALER IN D.M.,IOWA WHERE I LEASED THE CAR IN 2010, OR IF I FELT UNSAFE, I COULD TAKE IT TO ADAMS TOYOTA IN LEE'S SUMMIT, MISSOURI. THEN, MY DAUGHTER-IN-LAW CALLED ADAMS ON MY BEHALF AND THEY GAVE HER AN ENTIRELY NEW CASE NUMBER BECAUSE THE FIRST REP WHO TOOK THE REPORT DID NOT UNDERSTAND THERE WAS DAMAGE .MY NEW CASE # IS 1308011967. I FELT I NEVER WANT TO BE IN THAT COROLLA AGAIN, SO I DID TAKE IT TO ADAMS AND THEY PROVIDED ME WITH A SCION RENTAL TO GET BACK TO HOME AND WORK IN IOWA. TOYOTA HAS INSPECTED THE CAR AND HAS UP TO 30 DAYS TO GIVE ME THEIR REPORT. I AM TO RECEIVE A COPY OF THE DATA IMAGING EXTRACTED FROM THE BLACK BOX ALSO.
