2006 Toyota Land Cruiser

WE CAME HOME LATE AT WEDNESDAY NIGHT SEPT, 07 2011 AROUND 9:00 PM, SAW THE TAIL LIGHTS AND FRONT AMBER LIGHTS OF THE 2006 LAND CRUISER PARK AT THE DRIVEWAY WAS ON. I WENT INTO THE HOUSE TO GET THE KEY TO UNLOCK THE DOOR AND LOCKED IT BACK. WE WENT INTO THE HOUSE FOR 10 MINUTES AND CAME OUT SIDE AND THOSE LIGHTS ARE TURN ON AGAIN. I GOT THE KEY AGAIN AND THIS TIME I UNLOCK THE DOOR AND TRY TO START THE CAR AND FOUND OUT THE BATTERY ARE DEAD, I TRY VERY THINGS I CAN THINK OF TO TURN THOSE LIGHTS OFF, NO LUCK, I END UP TO OPEN THE HOOD TO DISCONNECT THE NEGATIVE BATTERY CABLE AND FOUND THE PLASTIC HORN ON THE GROUND AND HAD BEEN MELTED OFF FROM THE METAL HORN ITSELF. THE NEXT DAY SEPT, 08 2011. I TOOK THE BATTERY OUT AND PUT IN THE GARAGE TO CHARGE THE BATTERY BACK UP. ON FRIDAY SEPT, 09 2011, I PUT THE BATTERY BACK ON THE VEHICLE AND TURN THE CAR OVER, I DROVE ALL THE WAY TO A LOCAL TOYOTA DEALERSHIP AND TOLD THEM THE PROBLEM AND MAKE AN APPOINTMENT WITH THEM ON NEXT MONDAY SEPT, 12 2011. DROVE THE CAR HOME , LOCK THE CAR ABOUT 2 HOURS LATER CAME OUT AND FOUND THE LAND CRUISER LIGHTS ON AGAIN, WENT TO GET THE KEY AND TURN ON THE ENGINE AND THIS TIME THE DASH BOARD LIGHT ALSO FLASHING, THE CAR ENGINE RAN FOR ABOUT 3 MINUTES AND SUDDENLY THE ENGINE REV UP BY ITSELF AND STAYED REV. I STEP ON THE BRAKE PEDAL NOTHING CHANGE, AND ALSO TRY TO STEP ON THE ACCELERATOR PEDAL AND FOUND OUT THAT THE GAS PEDAL HAD NO RESPOND WHAT SO EVER WITH THE ENGINE SPEEDING UP. STUCK ACCELERATOR CONTROL? WAS THERE ANY OF THIS BEEN REPORTED? WAS THERE A RECALLED? *TR
