2003 GMC Yukon Denali Xl

WHEN DRIVING AT LOW SPEEDS (LESS THAN 10 MILES PER HOUR) OR STARTING FROM A STOP, THE TRACTION CONTROL WILL AUTOMATICALLY ENGAGE WHEN THE GAS PEDAL IS APPLIED. WHEN THE TRACTION CONTROL ENGAGES, A TOTAL LOSS OF INPUT TO THE ENGINE RESULTS AND THE VEHICLE DOES NOT MOVE (IT ESSENTIALLY STALLS). I WAS ALMOST STRUCK IN AN INTERSECTION WHILE WAITING TO MAKE A LEFT TURN ON A GREEN LIGHT IN EARLY DECEMBER OF 2011. I WAS STOPPED IN THE MIDDLE OF THE INTERSECTION WAITING TO TURN LEFT. WHEN I ATTEMPTED TO TURN LEFT, I GAVE THE GAS PEDAL SOME INPUT, THE TRACTION CONTROL ENGAGED, AND MY VEHICLE STOPPED BECAUSE THERE WAS NO ENGINE INPUT AND WAS ALMOST HIT BY AN ON-COMING CAR. LUCKILY, THIS HAD HAPPENED BEFORE AND I KNEW TO EITHER FLOOR THE GAS PEDAL OR TO LET OFF THE GAS ENTIRELY AND THEN FLOOR IT AGAIN TO GET THE TRACTION CONTROL TO DISENGAGE AND GET POWER TO THE ENGINE. ANOTHER RELATED ISSUE IS THE ABS ENGAGING FOR NO REASON. THIS ALSO HAPPENS AT LOW SPEEDS (LESS THAN 10 MPH). WHEN THE ABS ENGAGES, THE VEHICLE WILL TRAVEL ANOTHER TWO TO THREE FEET PRIOR TO STOPPING. THE ABS ISSUE RESULTED IN MY HITTING A POLE IN A PARKING LOT. IT TOOK SEVERAL YEARS TO FINALLY DETERMINE WHAT THE ISSUE WAS AND IT TURNS OUT IT WAS A RESULT OF FRONT WHEEL SPEED SENSOR CORROSION AND AN INCREASED AIR GAP BETWEEN THE WHEEL SPEED SENSOR AND THE RELUCTOR RING DUE TO RUST AND DEBRIS BUILT UP ON THE SENSOR MOUNTING SURFACE. GM ACKNOWLEDGED THIS WITH A SAFETY RECALL (#05068C: PRODUCT SAFETY) FOR SOME VEHICLE MODEL YEARS 1999-2002. THIS IS A SERIOUS SAFETY ISSUE AND GM FAILS TO RECOGNIZE THAT VEHICLES LIKE MINE (A 2003) AND EVEN LATER MODELS HAVE THE SAME PROBLEM. WHAT IS EVEN MORE FRUSTRATING IS THAT THE DEALERSHIP COULD NOT PROPERLY DIAGNOSE THE PROBLEM FOR SEVERAL YEARS BECAUSE THEY COULD NOT "REPLICATE THE PROBLEM ." I WOULD ENCOURAGE THE NHSTA TO INVESTIGATE THIS ISSUE. *KB

I WAS DRIVING MY YUKON 2003 DENALI AND THE ERROR MESSAGE SHOWED UP "REDUCED ENGINE POWER". I WASN'T ABLE TO GET THE SPEED UP TO 30 MPH ON THE HIGHWAY. I PULLED INTO A PARKING LOT AND HAD SOMEONE COME PICK ME UP. WHEN I WENT TO PICK UP MY VEHICLE, THE MESSAGE NO LONGER APPEARED AND IT FUNCTIONED AT NORMAL SPEEDS. I AM NERVOUS ABOUT TRAVELING WITH MY FAMILY IN THE VEHICLE NOW. *TR

TL*THE CONTACT OWNS A 2003 GMC YUKON DENALI. WHILE DRIVING AT APPROXIMATELY 65 MPH, THE ENGINE SHUT DOWN COMPLETELY WITH NO PRIOR WARNING. THE CONTACT WAS ABLE TO GET THE VEHICLE TO THE SIDE OF THE ROAD AND HAD IT TOWED TO AN AUTHORIZED DEALERSHIP. THE DEALER STATED THAT ALTHOUGH NOT CERTAIN, THE FUEL TANK COULD HAVE CAUSED THE FAILURE.
