NHTSA Complaint #10633440 — 2003 MERCURY MOUNTAINEER

ON THE BALTIMORE-WASHINGTON PARKWAY (295 N ) NORTHBOUND, CHANGED LANES TO THE LEFT AND ACCELERATED. THE GAS PEDDLE WAS PUSHED TO THE FLOOR, STAYED THERE AND WOULD NOT RELEASE. I STOOD ON THE BRAKES, BUT ONLY SOMEWHAT SLOWIED THE ACCELERATION. THE VEHICLE CONTINUED UNTIL WE REACHED ABOUT 80MPH AND COMING CLOSE TO REAR ENDING THE VEHICLE IN FRONT OF ME. I WENT OFF ON THE SHOULDER AND TURNED OFF THE IGNITION KEY TO GET THE VEHICLE STOPPED. THE BRAKE OVERHEATED BRAKES. I COULD NOT SEE A PROBLEM. THIS WAS NOT CAUSED BY A FLOOR MAT. THE PEDAL WAS STUCK TO THE FLOOR. I WIGGLED AND PULLED AND IT COME BACK UP WITH A POP. IN DAYLIGHT THE NEXT DAY, I INSPECTED THE PEDAL AND PUSHED IT DOWN. IT AGAIN WENT TO THE FLOOR AND STAYED THERE. I SLID UNDER THE DASH AND FOUND THAT THE HORIZONTAL PIN THAT HOLDS THE PEDAL TO THE FLOOR BRACKET HAD BACKED OUT SIDEWAYS FROM RIGHT TO LEFT, ALLOWING THE PEDAL TO GO SOMEWHAT SIDEWAYS AND THE MOTOR FOR THE ADJUSTABLE PEDAL ASSEMBLY HAD CAUGHT ON A METAL BRACKET KEEPING THE PEDAL FROM RETURNING TO THE UP POSITION. I REMOVED THE PEDAL ASSEMBLY AND INSPECTED THE PROBLEM. THIS IS POOR ENGINEERING AND THERE SHOULD BE A RECALL.. THERE ARE NO CLIPS OR PINS TO HOLD THE PEDAL PIN IN PLACE ! ! ! THE ASSEMBLY RELIES ON SLIGHT INTERFERENCE BETWEEN SPLINES ON THE PIN AND SPLINES INSIDE WHERE IT GOES THROUGH THE PEDAL. WHAT HAPPENED WAS, THAT OVER A PERIOD OF TIME, FROM THE PEDAL WIGGLING, THE PIN BACKED OUT.FROM USE, ON ITS OWN. AGAIN, THIS NOT SUFFICIENT TO KEEP THE PEDAL ASSEMBLED. IT NEED CLIPS ON BOTH ENDS OR COTTER PINS ON BOTH ENDS OF THE PIN ASSEMBLY. A CONCERN IS THE USE OF PLASTIC BRACKET TO MOUNT THE PEDAL TO THE FLOOR. IN MY PAST EXPERIENCE, THE MOUNTING BRACKETS HAD BEEN MADE OF METAL. PLASTIC FATIGUES FASTER THAN METAL AND IS PRONE TO CRACKING AND BREAKING. *TR
