MY WIFE WAS PARKING OUR 2008 TOYOTA SIENNA WITH OUR 3 YOUNG BOYS IN THE AUTOMOBILE. SHE SLOWLY BROUGHT THE VEHICLE TO A COMPLETE STOP; NEVER USING GAS, JUST COVERING AND TAPPING LIGHTLY ON THE BRAKE. ONCE THE AUTOMOBILE CAME TO A STOP MY WIFE PRESSED THE BRAKE A LITTLE MORE IN ORDER TO PUT THE VEHICLE IN PARK. AT THAT MOMENT THE VEHICLE ACCELERATED INCREDIBLE FAST, JUMPED OVER AN 8 INCH CONCRETE PARKING LOT DIVIDER AND CRASHED INTO A TREE ABOUT 10 - 15 FEET FROM THE CONCRETE DIVIDER. WE ARE CERTAIN THAT THIS WAS A "SUDDEN UNINTENDED ACCELERATION" INCIDENT CAUSED BY SOME MECHANICAL, ELECTRICAL, PROGRAMMING OR OTHER DEFECT IN THE '08 SIENNA. THIS WAS NOT "DRIVER ERROR"! MY WIFE DID NOT CONFUSE THE GAS PEDAL AND THE BRAKE. THIS WAS NOT CAUSED BY A FLOOR MAT OBSTRUCTING THE GAS PEDAL. THIS WAS CAUSED BY SOME TYPE OF A DESIGN OR COMPONENT DEFECT. HOW CAN W BE SO CERTAIN? MY WIFE AND I HAVE PARKED IN THIS PARKING SPOT (LOCATED IN OUR APARTMENT COMPLEX) HUNDREDS OF TIMES. TO PARK IN THIS PARKING SPOT YOU FIRST HAVE TO MAKE A LEFT HAND TURN AT A STOP SIGN. THIS STOP SIGN IS ABOUT 30 - 40 FEET FROM THE PARKING SPOT, WHICH REQUIRES THAT YOU MAKE A SHARP RIGHT TURN. ONCE YOU PRESS THE ACCELERATOR SLIGHTLY TO MAKE THE LEFT AT THE STOP SIGN, YOU DO NOT USE THE GAS AGAIN. YOU SIMPLY TAP AND COVER YOUR BRAKE UNTIL YOU MAKE THE RIGHT INTO THE PARKING SPOT. OUR VEHICLE CAME TO A STOP. IN FACT, UPON "STOPPING" ONE OF OUR 3 BOYS REMOVED HIS SEAT BELT IMMEDIATELY BEFORE THE VEHICLE ACCELERATED
