WHILE ATTEMPTING TO SHIFT FROM THIRD TO FOURTH THE ENGINE APPEARED TO HAVE A STUCK THROTTLE CABLE. PULLED THE TRUCK SAFELY OFF THE ROAD AND CHECK THE THROTTLE CABLE MAKING SURE IT WAS NOT BROKEN OR KINKED. I RESTARTED THE TRUCK AND THE RPMS AT IDOL WERE AT 2000 AND THEN I PLACED THE TRUCK INTO FIRST GEAR AND BEGAN TO MOVE FORWARD TOWARDS MY HOME. AS I SHIFTED FROM 1 TO SECOND THE RPMS BEGAN TO RISE. AS I PLACED THE TRUCK INTO NEUTRAL THE ENGINE CONTINUED TO INCREASE IN RPMS TO 3000 AND THEN ONTO 4000. I PLACED THE TRUCK IN NEUTRAL AND ALLOW THE MOTION OF THE ENGINE TO PUSH THE TRUCK FORWARD AND USING THE BRAKES I WAS ABLE TO KEEP SPEEDS BELOW 45 AND WHEN THE TRUCK CAME TO A COMPLETE STOP THE ENGINE RPMS CONTINUED TO RISE ABOVE 4000. AFTER GETTING THE TRUCK HOME AND INSPECTION OF THE THROTTLE BODY, A HALF CUP MOVABLE PLATE WAS FOUND ATTACHED TO THE BUTTERFLY..THIS HAD PREVENTED THE BUTTERFLY TO CLOSE AND HAD TORN FROM THE BUTTERFLY PLATE. I HAVE NOT FOUND ANY DOCUMENTATION ON THIS PLATE OR CUP ON ANY SITES NOR IS IT MENTIONED IN ANY OWNER MANUALS. I WAS LUCKY, BUT OTHERS WHO ARE NOT MECHANICALLY INCLINED MAY NOT KNOW WHAT TO DO OR EVEN AN INCREASE CHANCE OF AN ACCIDENT WHICH COULD RESULT IN A DEATH OR INJURY. *TR

I HAD AN ACCIDENT AT LOW SPEED BECAUSE OF UNWANTED (ABS) BRAKES ACTIVATION. I CONTINUE TO HAVE PROBLEMS AS I STOP AT LOW SPEED MY TRUCK MOVES FORWARD AGAIN AFTER THE STOP CAUSING A POSSIBLE ACCIDENT. I BOUGHT MY TRUCK IN FLORIDA. FOR THIS REASON MY VIN NUMBER IS NOT ON A RECALL LIST DUE TO THE FACT I PURCHASED IN A NON CORROSIVE STATE. I HAD TO COME TO OHIO QUITE OFTEN TO CARE FOR MY ILL MOTHER STARTING IN 2009. I ALSO HAVE EXPERIENCED PROBLEMS WITH THE SENSORS RECALLED, THE TAILGATE RECALLED(ACTUALLY FELL OFF THE TRUCK 3 TIMES WHILE I WAS ENROUTE), THE FUEL TANK PRESSURE SENSOR RECALL( NOT LETTING ME KNOW WHETHER I HAD GAS OR NOT), THE SEATS RECALL. ALL OF THIS DUE TO FAULTY PARTS CORRODING, AFTER I CAME TO OHIO, WHICH IS INCLUDED IN THE RECALL. I NEED MY VIN NUMBER ADDED TO THE RECALL SO I CAN HAVE THESE THINGS REPLACED BY A DEALER. I CANNOT DRIVE MY TRUCK NOW BECAUSE IT ISN'T SAFE. I HAVE TO TRANSPORT MY LITTLE GRAND CHILDREN AND ITS THE ONLY TRANSPORTATION I HAVE. *TR

WHEN HE HAD DIAGNOSED, THE DIAGNOSIS WAS A BAD CHIP OR ELECTRICAL PROBLEM, OR SWITCH. IT WOULD BE EXPENSIVE TO FIX.AT THIS TIME I WAS DIAGNOSED WITH BREAST CANCER & UNDERWENT SURGERY $ MOS. OF CHEMO. MY HUSBAND,MILITARY RETIREE, STAYED WITH ME IN HOSPITAL. AFTER MY CHEMO, HE HAD BOTH HIPS REPLACED AND WAS BEING TREATED UNTIL 2013 FOR SPINAL INJECTIONS. IN JULY 2013, HE WAS DIAGNOSED WITH STAGE 4 CANCER & PASSED AWAY IN AUGUST. IN THE MEANTIME, WHEN HE DROVE THE TRUCK HE RECORDED MILEAGE AFTER A FILL IN ORDER TO KEEP TRACK OF AMT. OF FUEL.I ALWAYS WORRIED ABOUT THIS AS BEING NON-SAFE, BUT HE COULD ONLY GET INTO A TRUCK BECAUSE OF HIS MEDICAL CONDITION, SO OUR CHOICES WERE LIMITED.NOW AFTER HIS PASSING, THE TRUCK IS IN MY NAME BUT I DO NOT DRIVE IT BECAUSE I AM AFRAID FOR MY SAFETY BECAUSE OF THE DEFECT.I AM STILL UNDER THE CARE OF AN ONCOLOGIST AND NEED THE TRUCK AT THIS TIME. ARE YOU ABLE TO HELP WITH THIS PROBLEM? IT WOULD RELIEVE THE STRESS & GIVE ME PEACE OF MIND REGARDING MY SAFETY. I AWAIT YOUR RESPONSE. I WAS REFERRED TO YOU BY THE NHTSA. *TR

ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.
