  TL* THE CONTACT OWNS A 2003 GMC YUKON DENALI. THE CONTACT STATED THAT THE TRACTION CONTROL AND THE REDUCED ENGINE POWER WARNING LIGHTS ILLUMINATED AND CAUSED THE VEHICLE STALLED. THE CONTACT WAS ABLE TO RESTART THE ENGINE, WHICH RESUMED NORMALLY. THE FAILURE WAS RECURRING. THE VEHICLE WAS TAKEN TO THE DEALER, WHO WAS UNABLE TO DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 213,000.

• 12/30/2011· SERVICE BRAKES, HYDRAULIC,ENGINE AND ENGINE COOLING,VEHICLE SPEED CONTROL,ELECTRONIC STABILITY CONTROL (ESC)Crash

  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

• 12/30/2006· ELECTRICAL SYSTEM

  IN OCT 06 MY SPEEDOMETER STARTED STICKING AND 120+ EVEN WHEN SITTING STILL. I CHECKED WITH A LOCAL SHOP AND WAS ADVISED IT WOULD NEED TO BE RECALIBRATED WHICH INVOLVED TAKING THE DASH APART SENDING IT OFF AND BEING WITHOUT A VEHICLE FOR 5-7 DAYS. I COULDN'T DO THAT AT THE TIME. SEVERAL WEEKS LATER IT JUST STARTED WORKING AGAIN AND HAD WORKED FINE UNTIL 12/22/06 AND NOW IT IS DOING IT AGAIN ALL THE TIME. I JUST THINK FOR WHAT THESE VEHICLES COST THESE KIND OF PROBLEMS SHOULD BE TAKEN CARE OF. I FEAR EVERYDAY OF GETTING A TICKET, BUT AT THIS TIME I CANNOT AFFORD THE REPAIR OR BEING WITHOUT MY VEHICLE FOR A WEEK. *NM

• 12/29/2006· ELECTRICAL SYSTEM

  IT STARTED THIS FALL MAYBE CLOSER TO WINTER. BUT ALL OF A SUDDEN THE SPEEDO STUCK AT ABOUT 70 MILES AN HOUR. AT FIRST I THOUGHT IT WAS A GLITCH BUT WHEN IT HAPPENED MORE AND MORE NOW I KNOW THAT IT IS A PROBLEM. THE SAFETY ISSUE IS THERE ARE OTHERS OUT THERE HAVING THE SAME PROBLEM AND WHEN YOU THINK YOU ARE GOING A CERTIAN MPH AND YOUR REALLY NOT SOME MIGHT GET FRUSTRATED WITH OTHERS EVEN THOUGH THEY MAY BE IN THE WRONG. I CAN JUST SEE ALL THE ROAD RAGE HAPPENING BECAUSE THEY THINK THEY ARE GOIND 70 AND THEY ARE REALLY GOING 80 OR MORE. I HAVE BEEN WATCHING MY TACHOMETER BUT I DONT KNOW WHAT OTHERS ARE DOING. THIS NEEDS TO BE ADDRESSED. BECAUSE I AM BEING TOLD THAT IT WILL COST 600+ TO FIX. HOW MANY OF THOSE HAVING THIS PROBLEM ARE GOING TO SPEND THAT KIND OF MONEY TO FIX A SPEEDOMETER?

• 12/29/2003· POWER TRAIN

  WE PURCHASED A 2003 GMC YUKON. BEFORE IT HAD REACHED 3000 MILES THE NEUTRAL LIGHT CAME ON ON THE 4X4 UNIT. FROM THERE IT WOULD SHIFT ITSELF INTO 4 LOW. WE HAVE HAD IT INTO THE DEALER A TOTAL OF 6 TIMES NOW AND THEY HAVE REPLACED ONE OF THE COMPONENTS 3 TIMES, TWO OF THE OTHER COMPONENTS ONCE. AFTER THE SECON D REPLACEMENT IT STARTED SHOWING NEUTRAL AGAIN ON THE 4X4 UNIT. IT SEEMS AS THOUGH THE PROBLEMS DO NOT ARISE UNTIL AFTER 1000 MILES. THE DEALERSHIP SERVICE DEPARTMENT TOLD ME THAT THEY HAVE HAD A LOT OF PROBLEMS WITH THESE UNITS. WE ARE TRYING TO DO A BUY BACK BUT GM IS DRAGGING THINGS OUT AND GIVING US A HARD TIME.*AK

• 12/27/2013· SERVICE BRAKES

  I WAS TRAVELING ON A TWO LANE COUNTY ROAD LOCATED IN OLDHAM COUNTY KENTUCKY AND UPON APPROACHING A CURVE, I ATTEMPTED TO APPLY THE BRAKE TO SLOW THE VEHICLE BUT THE BRAKE PEDAL WENT TO THE FLOOR AND PROVIDED NO BRAKING ACTION (SEVERELY RUSTED BRAKE LINES BURST AND RESULTED IN TOTAL BRAKE FAILURE ). THE CURVE WAS FOLLOWED BY AN INTERSECTION WITH A STOP SIGN IN MY LANE. LUCKILY THERE WERE NO VEHICLES IN FRONT OF ME AND NO OPPOSING TRAFFIC AT THAT MOMENT, WHICH ENABLED ME, THROUGH THE USE OF GEARS AND THE EMERGENCY BRAKE, TO GET THE VEHICLE STOPPED JUST BEYOND THE STOP SIGN. IT WAS MY UNDERSTANDING THAT MODERN VEHICLES WERE DESIGNED WITH REDUNDANCY IN THE BRAKING SYSTEM WHICH WOULD PREVENT TOTAL BRAKING FAILURE, BUT APPARENTLY THAT IS NOT TRUE WITH THIS VEHICLE. I HAVE READ SEVERAL ACCOUNTS OF SIMILAR FAILURES WITH THIS FAMILY OF VEHICLES AND I THINK ACTION NEEDS TO BE TAKEN QUICKLY AS THE NEXT VICTIM MAY NOT BE AS FORTUNATE AS ME AND MY 10 YEAR OLD GRANDDAUGHTER WERE THIS PAST WEEK. *TR

  MY HEATED SEATS STOPPED WORKING. WHEN MY TRUCK WAS IN THE SHOP WITH MY MECHANIC I ASKED IF HE COULD LOOK AND SEE WHAT THE ISSUE IS. WHEN HE TOOK APART THE SEAT THE HEATING PAD WAS BURNT TO A CRISP. HE CALLED THE GM DEALER NEAR BY AND ASKED WHAT THE ISSUE COULD BE AND THEY SAID A SHORT IN THE HEATING PAD WIRE. THIS PART OBVIOUSLY CAUGHT FIRE IN MY VEHICLE. I CALLED GM CORPORATE TODAY AND THEY SAID SINCE THE REPAIR WAS NOT DONE AT GM THERE IS NOTHING THEY WILL DO FOR ME. MY CAR COULD HAVE COMPLETED CAUGHT FIRE WITH MYSELF AND MY DAUGHTER IN IT. JUST BECAUSE THE REPAIR WAS NOT DONE THERE BUT THE PARTS WERE BOUGHT AT THE GM DEALER THEY WONT REIMBURSE ME FOR THE PARTS AND LABOR. THIS IS NOT A RECALL ITEM FROM WHAT I CAN SEE ONLINE. *TR

• 12/16/2011· ENGINE AND ENGINE COOLING,ELECTRICAL SYSTEM,ELECTRONIC STABILITY CONTROL (ESC)

  I HAVE HAD MULTIPLE ONGOING ELECTRICAL ISSUES WITH THIS VEHICLE. STARTING IN 2005, THE EXTERIOR ELECTRONICS (I.E. SIGNAL LIGHTS, STOP LIGHTS, HEAD LIGHTS, ETC) BEGAN TO MALFUNCTION. FOR EXAMPLE, I WOULD TRIGGER THE SIGNAL FOR ONE DIRECTION AND ALL OF THE SIGNALS FOR ALL DIRECTIONS WOULD TRIGGER... EVEN PRESSING THE BRAKES TRIGGERED ALL OF THE EXTERIOR SIGNALS. THE DEALER HAD A HARD TIME ISOLATING MY PROBLEM, BUT AFTER SEVERAL VISITS, THE DEALER WAS FINALLY ABLE TO DIAGNOSE AND RECTIFY IT... THEY ISOLATED IT TO A JUNCTION BOX WHERE ALL OF THE ELECTRONICS TERMINATE. HOWEVER, BY THIS TIME, MY VEHICLE WAS OUT OF WARRANTY, SO I HAD TO COVER THE COSTS FOR REPAIRING THE PROBLEM MYSELF. MY MOST RECENT ISSUES, WHICH, BY THE WAY, SEEM TO BE COMMON ISSUES, ARE TRIGGERED BY A MESSAGE STATING, "REDUCED ENGINE POWER". THIS PARTICULAR ISSUE DOES NOT ALWAYS RENDER THE SAME RESULTS... SOMETIMES THE VEHICLE'S SPEED WILL SIGNIFICANTLY DECREASE TO NEARLY A HALT, BUT OTHER TIMES I MAY JUST EXPERIENCE INCREASED IDLING OF THE ENGINE, EVEN IF I AM AT A COMPLETE STOP. MY UNDERSTANDING, ACCORDING TO HUNDREDS OF REPORTS THAT I HAVE READ ON THE MESSAGE BOARDS, IS THAT THIS ISSUE IS CAUSED BY EITHER A WIRING HARNESS THAT LEADS FROM THE ACCELERATOR TO THE THROTTLE BODY OR IT'S A DEFECTIVE THROTTLE BODY ALTOGETHER. I HAVE EXPERIENCED INTERMITTENT ELECTRICAL PROBLEMS WITH MY WINDOWS AS WELL, BUT THIS APPEARS TO BE A MINOR ISSUE WHEN COMPARED TO THE OTHER TWO THAT I ADDRESSED ABOVE. I WILL FILE A FORMAL COMPLAINT WITH GMC CORPORATE OFFICE TODAY AND SEE WHERE THAT GOES. *TR

  ALL AUTOMOBILES IN NORTH-AMERICA SHOULD HAVE STAINLESS STEEL BRAKE LINES AND FUEL LINES TO PREVENT CORROSION, IT ONLY MAKES SENSE AND ITS NOT THE END OF THE WORLD AS FAR AS COST; BRAKE FAILURE IS PROBABLY THE MOST DANGEROUS THING THAT CAN HAPPEN THAT CAN BE LIFE THREATENING. I AM AWARE THAT AUTO MANUFACTURERS WANT US TO REPLACE COMPONENTS AND MAKE MONEY DOWN THE LINE, BUT BRAKE COMPONENTS SUCH AS BRAKE LINES HAVE TO BE EXCLUDED FROM THIS. *TR
