AFTER TAKING TWO SHORT 90 DEGREE TURNS AT A PARKING FLOOR (4TH FLOOR), THE VEHICLE WAS HALF WAY IN THE PARKING SLOT WHEN IT SUDDENLY PICKED UP SPEED AND CRASHED INTO WIRE CABLES AND A CONCRETE POST. THIS TYPE OF SPEED HAD HAPPENED TWICE IN THE PAST WITHIN THREE MONTHS OF PURCHASING THE CAR AS A NEW VEHICLE (BROUGHT IN JAN 2010). AFTER THE 2ND SUCH INCIDENT THE VEHICLE WAS TAKEN TO THE DEALER. THEY COULD NOT DUPLICATE THE ISSUE. THE VEHICLE HAD BEEN TAKEN IN THE PAST FOR GPS CHECK AS WELL. SUBSEQUENTLY THE VEHICLE WAS ASKED TO BE BROUGHT IN FOR A RECALL SERVICE AND THAT WAS COMPLETED AS WELL. THIS INCIDENT WAS THE NEXT TIME WHEN TRYING TO BRAKE TO COME TO A SLOW SPEED IT PICKED UP SPEED. WROTE TO TOYOTA WITH ALL DETAILS BUT THEY SAY THAT THEY COULD NOT DUPLICATE THE ISSUE AND THE VEHICLE DOES NOT SEEM TO HAVE FAULTS. OUR CONCERN IS JUST THAT - THEY CANNOT DUPLICATE THE ISSUE WHICH MEANS IT CAN HAPPEN ANYTIME WITHOUT ANY WARNING. WE ARE 100% SURE THIS WAS NOT DRIVER ERROR AND THAT IT WAS IDENTICAL TO THE PAST INSTANCES. TOYOTA EXPECTS US TO DRIVE THIS VEHICLE WE BELIEVE HAS SOME FORM OF A FAULT. THEY WERE NOT WILLING TO DRIVE IT TO AND FROM THE TEST LOCATION EVEN AFTER THEY SAY THE TEST REVEALED NO FAULTS - THEY HAD IT TOWED BOTH WAYS. THIS IS A PURE SAFETY ISSUE AND THIS CAR SHOULD NOT BE ON THE ROAD EVER AGAIN. MANY PEOPLE CAN GET HURT OR DIE DUE TO PURE CALLOUSNESS OF A VEHICLE MANUFACTURER. TOYOTA MAY MANUFACTURE AND DESIGN GREAT VEHICLES BUT THEY SHOULD ALSO TAKE RESPONSIB
