2008 Ford F-450 Sd

I TRAVEL FOR WORK AND DRIVE MANY DIFFERENT TYPES OF RENTAL CARS. I HAVE HAD THE FOLLOWING OCCUR IN MORE MODELS THAN I CAN REMEMBER. VEHICLE ACCELERATES WHEN YOU APPLY THE BRAKES. ROOT CAUSE: THE ELEVATION / SPACING RELATIONSHIP BETWEEN THE BRAKE PEDAL AND THE ACCELERATOR. OPERATOR ERROR CONTRIBUTES TO THE PROBLEM ALSO. PEOPLE HAVE A TENDENCY TO ROLL THEIR FOOT FROM THE GAS PEDAL TO THE RIGHT HAND SIDE OF THE BRAKE PEDAL. DEPENDING ON THE ANGLE OF THEIR FOOT, THE EDGE OF THEIR SHOE WILL HANG OVER THE GAS PEDAL. WHEN THEY APPLY THE BRAKE THEY ALSO APPLY THE GAS. THE ENGINE TORQUE OVER COMES THE BRAKE FRICTION AND THE CAR ACCELERATES. MOST OF THE TIME WHEN THIS HAPPENS I CAN REMOVE MY FOOT, RELOCATE IT ON THE BRAKE PEDAL AND SAFELY STOP. SEVERAL TIMES MY SITUATION REQUIRED ME TO HOLD THE BRAKE / GAS PEDALS IN POSITION AND QUICKLY USE MY LEFT FOOT TO APPLY THE BRAKE TO PREVENT AN ACCIDENT. WEARING MY HEAVY BOOTS WITH A LARGE SOLE INCREASES THE FREQUENCIES OF THESE INCIDENTS. *TR

HAVE HAD ACCELERATION ISSUES WITH THIS FORD F-450 SINCE APRIL OF 2010, THE FIRST TIME THE DRIVER WAS ABLE TO STOP THE VEHICLE WITHOUT INCIDENT BUT THE ENGINE BLEW UP WHEN HE PUT IT IN NEUTRAL TO STOP THE VEHICLE. IT WAS AT THE FORD DEALERSHIP FOR 6 WEEKS, I RETRIEVED THE VEHICLE, WHILE ON THE WAY HOME THE ENGINE FAILED AGAIN, IT WAS TOWED BACK TO THE DEALERSHIP. 1 WEEK LATER I RETRIEVED THE VEHICLE AGAIN, 2 DAYS AFTER THAT THE ACCELERATOR STUCK ONCE AGAIN WHILE HAULING A TRAILER LOADED WITH A RENTAL TRENCHER. THIS TIME THE RESULT WAS A TRAFFIC ACCIDENT THAT SENT ONE OF MY EMPLOYEES TO THE HOSPITAL AND CAUSED MAJOR PROPERTY DAMAGE, THE VEHICLE WAS TOWED BACK TO THE DEALERSHIP AND HAS BEEN THERE EVER SINCE. THEY HAVE REPLACED THE SHORT BLOCK, INJECTORS, AND OTHER VARIOUS ENGINE COMPONENTS. *TR

TRUCK HAS A DEAD THROTTLE W/O ANY NOTICE. I CAN DRIVE MY KIDS AROUND ALL DAY AND TRY TO CROSS TRAFFIC AND I HAVE LOST THROTTLE RESPONSE. THIS FIRST OCCURRED WHEN TRUCK HAD ABOUT 800 MILES ON IT. IT NEVER FLASHED A CODE SO I WAS SENT AWAY WITH A BUTTON TO PRESS WHEN IT WOULD DO IT AGAIN. AFTER WEEKS IN SERVICE THE MAP SENSOR WAS CHANGE. PROBLEM WAS FIXED BUT OCCURRED AGAIN WITHOUT NOTICE ABOUT A YEAR LATER. MAP SENSOR WAS CHANGED AGAIN PROBLEM FIXED. TRUCK IS ONCE AGAIN EXPERIENCING THIS DEAD THROTTLE CURRENTLY AND AM NOT SURE WHAT TO DO. I TOOK IT TO THE DEALER AND THEY SAID NO CODES CAME THROUGH. I AM DRIVING A POTENTIAL DEATH TRAP. *TR
