THERE IS NO WARNING CODE FOR THE HYDRAULIC BRAKE BOOSTER WHEN IT STARTS TO GO BAD THAT SHOWS UP ON THE ABS/ODB SCANNER. YOU WILL BE DRIVING AND ALL OF THE SUDDEN YOUR STEERING GETS STIFF, THE BRAKE PEDAL IS HARD TO PRESS AND YOU CAN'T STOP AS GOOD AS YOUR USED TO IN THE VEHICLE. THIS ISSUE CAN CAUSE ACCIDENTS IF SOMEONE STOPS SUDDENLY IN FRONT OF YOU.

THE STABILITY CONTROL WARNING HAS COME ON SEVERAL TIMES ON MY VEHICLE. THE BRAKES DO NOT WORK, AS YOU HAVE TO PUSH ALL THE WAY TO THE FLOOR AND SOMETIMES IT TAKES TIME BEFORE THE VEHICLE STOPS. I HAVE HAD BRAKE LINES REPAIRS AND THE PROBLEM STILL IS THERE. WE CANNOT USE VEHICLE UNTIL THE ISSUE IS RESOLVED. OUR MECHANIC ADVISED US TO FILE A COMPLAINT ON THIS ISSUE BECAUSE IT IS AN ACTIVE ISSUE WITH GMC DENALI YUKON'S FOR YEARS. WE NEED ASSISTANCE TO HAVE THIS RESOLVED TO USE OUR VEHICLE.

VEHICLE POWERS DOWN WITHOUT ANY PATTERN, RHYME OR REASON. IT WILL DO IT AT 5 MPH, AND AT 55 MPH, WHEN DRIVEN A LOT, AND WHEN NOT. REDUCED ENGINE POWER LIGHT TURNS ON, VEHICLE SUDDENLY SLOWS TO 25 MPH MAX, STEERING BECOMES HARD, BRAKES TOO. THEN WILL TOTALLY SHUT OFF IMMEDIATELY. I HAVE REPLACED THE BATTERY, THROTTLE BODY ASSEMBLY AND WIRING HARNESS TWICE. FUSES, FUEL PUMP AND FILTERS, OIL, AND EVERYTHING ELSE AS RECOMMENDED. IT PUT ME IN THE DITCH. IT STRANDED ME IN THE CENTER OF A FREEWAY IN WINTER. WHEN IT SITS FOR A WHILE, IT RESETS, ONLY TO DO IT AGAIN. T/C LIGHT TURNS ON ALSO. I FOUND OUT THAT I CAN MANUALLY RESET THE REDUCED ENGINE POWER FOR A FEW MOMENTS (TO GET OUT OF THE CENTER OF THE ROAD) BY TURNING THE IGNITION SWITCH ON AND OFF VERY FAST. IT IS A EXTREME SAFETY HAZARD! I HAVEN'T DRIVEN IT IN MONTHS DUE TO ABSOLUTE FEAR FOR MY LIFE. WHEN ITS IN REDUCED ENGINE POWER MODE, I CAN'T GET IT TO GO ABOVE 25, AND GOING UP HILLS CAN'T GO ABOVE 5MPH. IF I AM PULLING A TRAILER, IT STARTS TO GO BACKWARDS. THIS THING IS GOING TO KILL SOMEONE! PLEASE HELP *TR

I WAS DRIVING DOWN THE ROAD TO WORK AND I HIT THE BRAKES AND THE BRAKE PEDAL WAS NOT FIRM. I HIT THE BRAKE PEDAL AGAIN AND THE BRAKE PEDAL WENT TO THE FLOOR. I HAD A HARD TIME STOPPING THE BIG SUV AND WOULD HAVE HIT ANOTHER CAR HAD THIS HAPPENED AT A STOP LIGHT OR ANYWHERE WHERE I HAVE TO RELY ON MY BRAKES AS THE STOPPING DISTANCE WAS EASILY QUADRUPLED IF NOT MORE. *TR

INTERMITTENTLY AT HWY AND SIDE ROAD SPEEDS, TRUCK WILL SHUT DOWN, CHECK ENGINE LIGHT COMES ON AND EXTREMELY ROUGH IDLE AND LOSS OF ENGINE POWER OCCURS. HAVE FOLLOWED ALL RECOMMENDED FIXES BUT PROBLEM PERSISTS. ENGINE CODE 1516, THROTTLE POSITION SENSOR OUT F RANGE +- .05 VOLTS. SCARY PROBLEM, AS THIS OCCURS WITHOUT WARNING AND CAUSES IMMEDIATE LOSS OF SPEED. MANY MANY COMPLAINTS POSTED ON THE INTERNET OF THIS SAME PROBLEM BUT NO GMC RECOMMENDED FIXES OR ASSISTANCE. REFUSE TO TAKE THIS TO A DEALER AND LET THEM POKE AROUND AT $95 / HOUR AND OR TO THROW PARTS AT TRUCK IN HOPES OF CORRECTING. GMC NEEDS TO ADDRESS THIS POTENTIALLY FATAL PROBLEM. *TR

DRIVING TO WORK AND "REDUCE ENGINE POWER" CAME ON. ENGINE STALLED OUT AND WOULD NOT GAIN SPEED. I WAS IN A LOT OF TRAFFIC WHEN THIS HAPPEN AND MY VEHICLE CAUSE A INCIDENT BECAUSE OF THE SUDDEN ENGINE REDUCED ALL SPEED. GMC SHOULD DO SOME RESEARCH ABOUT THIS PROBLEM AND INFORM THE PUBLIC OF ALL THE DANGERS THESE VEHICLES ARE CAUSING FOR PUBLIC TRANSPORTATION. THIS IS LUDICROUS THAT GMC DOES NOT HAVE THESE VEHICLE OFF HE STREETS AND DESTROYED KNOWING THAT THEY ARE PUTTING PEOPLE LIVES IN DANGER. I WILL NEVER EVER BUY A GMC VEHICLE AGAIN. *TR

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
