2012 TOYOTA HIGHLANDER Fuelpropulsion System Problems

WHEN FILLING THE HIGHLANDER WITH FUEL, IT LOOKS LIKE A WATERFALL OF FUEL LEAKING ONTO THE GROUND. IT DOES NOT APPEAR TO BE A GAS TANK ISSUE BUT A PROBLEM WITHIN THE LINES? ONCE YOU STOP FUELING WITH THE MAJOR LEAK AND GO TO ANOTHER AREA THERE IS NO FUEL DROP UNDERNEATH THE TANK.

ON (OR ABOUT) THE LAST WEEK OF MAY 2015, I HAD MY AUTO SERVICED AT THE DEALSHIP. I WAS ADVISED THAT THE 'THROTTLE BODY' NEEDED 'CLEANING' AND THIS WAS DONE BY THE DEALERSHIP AT THAT TIME. ON JUNE 4, 2015, I WAS BACKING INTO A PARKING SPOT ON A PARKING LOT, WIITH THE CAR 'COASTING' BACK AND MY FOOT ON THE BRAKE. ABOUT HALF WAY INTO THE 'SPOT' THE CAR ENGINE SUDDELY ACCELLERATED AND I HAD TO USE EXTREME PRESSURE ON THE BRAKE PEDAL TO OBTAIN A 'MINIMUM' OF SLOWING. THE CAR ONLY CAME TO A STOP WHEN THE REAR TIRES, MADE CONTACT WITH AN 'IN-PLACE' CEMENT PARKING BARRIER AND THE ENGINE ACCELERATION ONLY CEASED WHEN I PUT THE CAR IN 'PARK' GEAR. IT HAS NOT OCCURED SINCE, NOR HAS IT EVER OCCURED WHILE DRIVING FORWARD. I AM A RETIRED POLICE OFFICER WITH YEARS OF TRAINING IN DRIVING AND DRIVER...

MY HIGHLANDER WAS AT THE AIRPORT FOR THREE DAYS PARKED. WHEN I WAS LEAVING THE LOT I WAS DRIVING SLOW IN THE LOT TO PAY MY PARKING. WHEN I GOT OUT OF THE LOT TO MAIN STREAM TRAFFIC I TRIED TO ACCELERATE AND THE CAR WOULD ONLY GO SLOW AS I KEPT PUSHING THE THROTTLE. THERE WERE CARS ON BOTH SIDES OF ME WITH NO ONE IN FRONT AND THEN THE CAR JUST TOOK OFF. IT DID STARTLE ME BECAUSE I WAS NOT EXPECTING THIS. THANK GOD NO ONE WAS IN FRONT OF ME BECAUSE I AM SURE I WOULD NOT HAVE REACTED FAST ENOUGH TO STOP BECAUSE OF THE RAPID ACCELERATION. SOMETHING IS WRONG WITH THE THROTTLE IN THESE VEHICLES. I DID NOT TAKE IT IN BECAUSE I AM SURE THEY WOULD NOT HAVE BEEN ABLE TO REPRODUCE THE PROBLEM. THIS HAS ONLY HAPPEN ONCE AND I HOPE IT...
