NHTSA Complaint #10508399 — 2006 DODGE DURANGO

THE VEHICLE, ON COLD START UP EXHIBITED A SURGING IDLE, FROM 500 RPM RANGING UP TO 2000 RPM. THE IDLE FINALLY LEVELED OUT AND SETTLED DOWN. WHILE DRIVING THE VEHICLE, I NOTED SOME SURGING PRESENT WHILE AT A STEADY SPEED. ONCE, WHILE SITTING AT A TRAFFIC LIGHT WHILE IN DRIVE, THE VEHICLE IDLE JUMPED UP AND CAUSED THE VEHICLE TO LUNGE INTO THE INTERSECTION. LUCKILY NO CROSS TRAFFIC WAS PRESENT AND APPLYING THE BRAKES VERY HARD STOPPED THE VEHICLE FROM COMPLETELY RUNNING THROUGH THE INTERSECTION. THERE WAS NO CHECK ENGINE LIGHT PRESENT, NOR HAS THE CHECK ENGINE LIGHT EVER ILLUMINATED ON THIS VEHICLE, (OTHER THAN THE BULB CHECK ON START UP), FOR ANY REASON. AS AN ASE MASTER AUTOMOBILE TECHNICIAN AND A FORMER CHRYSLER FACTORY TRAINED TECHNICIAN, I CONNECTED A SCAN TOOL TO THIS VEHICLE TO SEE WHAT WAS GOING ON. AS STATED, THERE WAS NO CEL, SO THERE WERE NO CODES ACTIVE, PENDING OR HISTORICAL. OBSERVATION OF THE LIVE DATA STREAM REVEALED NOTHING OUT OF THE ORDINARY. WITH ACCESS TO IDENTIFIX, I RESEARCHED AND FOUND SEVERAL OTHER INSTANCES OF THE SAME CONCERN WITH 2006 DURANGOS, WITH RECOMMENDATIONS OF REPLACING THE THROTTLE BODY ASSEMBLY DUE TO INTERMITTENT "GLITCHES" IN THE THROTTLE POSITION SENSOR SENDING FALSE READINGS TO THE PCM CAUSING THE IDLE CONTROL MOTOR TO INCREASE THE IDLE SPEED. I CURRENTLY HAVE THIS PART ON ORDER FROM MY LOCAL DEALERSHIP. ONCE RECEIVED AND INSTALLED I WILL DETERMINE IF FURTHER ACTION WILL BE REQUIRED. *TR
