2003 GMC YUKON DENALI Recalls, Complaints & Safety

LOSS OF POWER WITHOUT WARNING , WHILE ON HIGHWAY. FROM 65MPH TO 0 WITHOUT WARNING. ALMOST CAUSED A CRASH PILE UP....WAS ALMOST REAR ENDED. VERY DANGEROUS...WHOLE FAMILY CHILDREN AND ALL WAS IN THE VEHICLE.

I LIVE IN FLORIDA- IT WAS APPROX 8 AM, SITTING OUTSIDE DRINKING COFFEE ON MY PORCH. VEHICLE HAD BEEN PARKED SINCE PRIOR AFTERNOON AND WAS LOCKED (ALARM ENGAGED). SUDDENLY, MY REAR WINDOW SPONTANEOUSLY 'EXPLODED'. THERE WAS GLASS EVERYWHERE BOTH INSIDE AND OUTSIDE OF THE VEHICLE. AFTER RESEARCHING WHAT COULD'VE CAUSED SOMETHING LIKE THIS TO HAPPEN, THERE ARE INNUMERABLE REPORTS OF THIS HAPPENING TO OTHER GMC OWNERS WITHOUT ANY PLAUSIBLE EXPLANATION. THIS IS A VERY CONCERNING ISSUE AS GLASS FLEW EVERYWHERE IN AND AROUND MY VEHICLE AND IT IS BY PURE LUCK THAT MY 15 YEAR OLD DAUGHTER AND USUALLY AT LEAST 1-2 OF HER FRIENDS, ALONG WITH MY ONE YEAR OLD DAUGHTER, WHO NATURALLY, IS IN THE REAR OF THE VEHICLE. MYSELF OR ANYONE ELSE MERELY WALKING BY THE VEHICLE COULD'VE BEEN INJURED JUST WALKING BY. HAD SOMEONE BEEN NEAR MY VEHICLE IN A PUBLIC PLACE, I.E. GROCERY STORE PARKING LOT, ETC. THEY COULD'VE BEEN INJURED BY THE SHARDS OF GLASS THAT SHOT OUT AND LANDED 4+ FEET FROM THE VEHICLE, LEAVING ME AT RISK OF FURTHER CIVIL ACTIO AND POSSIBLE SUIT. I AM ALSO A PROTECTIVE INVESTIGATOR FOR THE STATE OF FLORIDA AND OFTEN TIMES HAVE OTHER CHILDREN IN MY VEHICLE. THIS IS BOTH A HUGE CIVIL, AND MOST IMPORTANTLY, SAFETY CONCERN. THIS IS NOT OKAY AND IS NOT A FLUKE INCIDENT BASED UPON SO MANY REPORTED INCIDENTS FROM SO MANY OTHER GMC OWNERS. GMC REFUSES TO HELP. A RECALL ON THESE REAR WINDSHIELDS ARE A MUST AND I CANNOT BELIEVE THAT ONE IS NOT BEEN ISSUED IN ALL OF THE YEARS THAT THIS HAS BEEN HAPPENING TO PEOPLE. THIS IS NOT OKAY.

I HAVE A 2003 YUKON DENALI I PURCHASED AND IT HAS GIVEN ME THE REDUCED ENGINE POWER LIGHT AND ALMOST HAD A FEW ACCIDENTS ON THE HIGHWAY BECAUSE IT DROPS THE SPEED TO 20 MPH ALSO IT HAS THE CHECK ENGINE CODES AS P0120 AND P2135 I HAVE BEEN AWARE THAT GM HAS NOT FOUND A SOLUTION TO THIS AND WANTED TO SEE IF THERE IS ANY RECALLS AS I AM VERY AFRAID OF BEING IN A VERY SERIOUS ACCIDENT WITH MY CHILDREN IN THE CAR. THE CONSUMER STATED THE VEHICLE WAS REPAIRED AND REQUESTED WITHDRAW THE COMPLAINT. *JS

MY VEHICLE, DUE TO FACTORY ALARM SYSTEM, IS UNSAFE AND UNFIT TO DRIVE -- A DEATH TRAP ON WHEELS. IT TURNED THE VEHICLE OFF, WHILE DRIVING, AND LOCKED ME INSIDE! I WAS THANKFULLY DRIVING DOWN THE FL KEYS, ON A BRIDGE BUT AT THE END OF THE BRIDGE, SO I WAS ABLE TO COAST DOWN AND OFF THE BRIDGE TO A SHOULDER... IF IT HAD DIED ANYWHERE ELSE ON THE BRIDGE OR ON AN FLAT ROAD I MAY HAVE BEEN STUCK THERE, BLOCKING TRAFFIC AT THE MINIMUM, IN AN ACCIDENT AND DEAD IF REAR-ENDED AND PUSHED OFF BRIDGE...BECAUSE THE DOORS LOCKED AND I WOULD HAVE BEEN UNLIKELY TO ESCAPE MY SINKING TRUCK...TO SAY NOTHING OF THE FALL ITSELF. IF I HAD BEEN GOING ON THE INTERSTATE AND I WAS IN A MIDDLE LANE FOR EXAMPLE, I COULD HAVE EASILY DIED BECAUSE MY TRUCK SUDDENLY STOPPED, WITHOUT INDICATION, AND I GOT REAR ENDED BY ANY NUMBER OF VEHICLES, INCLUDING LARGE SEMI TRUCKS. IF I HAD A DEAD KEYCHAIN FOB FOR THE ALARM, I WOULD HAVE BEEN LOCKED INSIDE THE TRUCK AS WELL -- BECAUSE ONLY THE KEYCHAIN WAS ABLE TO UNLOCK THE DOORS. IF MY PHONE HAD DIED OR I HAD NO SIGNAL, I WOULD BE TRAPPED INSIDE AS WELL IF AND UNTIL HELP ARRIVED UNLESS I GOT DESPERATE ENOUGH TO SMASH OUT A WINDOW. ALL THE MECHANICS I HAVE TAKEN IT TO HAVE STRUGGLED TO RESOLVED THE ISSUE, BUT IT IS SOMETHING THE TRUCK SHOULD HAVE BEEN RECALLED FOR AND FIXED FOR FREE BY GMC -- A SERIOUS SAFETY ISSUE. I HAVE RESEARCHED AND SEEN OTHER SIMILAR TRUCKS BY GMC HAVING THE SAME PROBLEM WITH FACTORY ALARMS AND MY MECHANIC SAYS HE HAS HAD 2 OTHER, DIFFERENT MAKES/MODELS, JUST ARRIVE WITH NEARLY SAME PROBLEM, AS IF BY FATE AND HE IS HAVING TROUBLE FIXING THOSE AS WELL -- BECAUSE ITS A FACTORY EMBEDDED ALARM PROBLEMS. IT REMAINS UNFIXED TO THIS DAY AND I AM NOT ABLE TO DRIVE THE VEHICLE UNTIL IT IS FIXED.

I WAS TRAVELING SOUTH ON SUMMIT CROSSING RD. FREDERICKSBURG VA. 22408 AT APPROX.45 MIL.PER HR. ,WHEN I HEARD A BIG BANG ,THE STEERING LOCKED ,THE VEHICLE WENT DIRECTLY HARD LEFT,AND STRUCK LARGE TREES DESTROYING THE FRONT END. ABOUT 3 MINUTES AFTER THE CRASH THE STEERING WHEEL AIR BAG WENT OFF IN MY FACE.I EXITED THE VEHICLE TO FIND A DAMAGED FRONT WHEEL AND BROKEN AXLE ASSEMBLY NEAR THE VEHICLE.

Crash

BRAKES LINES RUSTED WHICH LED TO CATASTROPHIC FAILURE OF BRAKE SYSTEM. REPAIR COST $1,000. THERE ARE MULTIPLE THOUSANDS OF COMPLAINTS REGARDING THIS TYPE OF BRAKE FAILURE IN THIS MAKE, MODEL, & YEAR. THIS SHOULD BE A MANDATORY FACTORY RECALL. SOMEONE IS GOING TO DIE BECAUSE GM IS NOT BEING FORCED TO FIX THEIR FAULTY EQUIPMENT. MY VEHICLE WAS IN MOTION AND WHEN I DEPRESSED THE BRAKE PEDAL THE PEDAL WENT COMPLETELY TO THE FLOORBOARD. I WAS DRIVING STRAIGHT AHEAD IN MODERATE CITY TRAFFIC & NARROWLY MISSED STRIKING THE VEHICLE IN FRONT OF ME ON A CITY STREET. MY MASTER CYLINDER WAS COMPLETELY EMPTY OF BRAKE FLUID WHEN EXAMINED. I WAS TRAVELING 25 MPH AND MY VEHICLE HAS 110,000 MILES. (THE NEXT PAGE WOULDN'T ALLOW ME TO ENTER THE SPEED & MILEAGE INFORMATION WHERE IT WAS REQUESTED)

BRAKES FAILED WHILE DRIVING ON CITY STREET WITH NO WARNING COULD NOT STOP AT RED LIGHT. IMMEDIATELY PULLED OVER AND NOTICED BRAKE FLUID LEAKING FROM LEFT SIDE OF VEHICLE FROM A BROKEN BRAKE LINE.

TRUCK STARTED TO HAVE MAJOR ELETRICAL ISSUES. BLUBS BURNING OUT OFTEN SOCKETS BURNING OUT HAD TO REPLACE TOO OFTEN. LIGHT COVERS MELTING. HEADLIGHTS OUT AND WILL NOT COME BACK ON FOR DAYS, HAVE TO TAP THEM TO GET THEM TO COME BACK ON. HORN BLOWS FROM ALARM ALL TIMES OF THE DAY AND NIGHT. INSIDE LIGHTS ON DASH, STEERING WHEEL AND DOORS WILL NOT WORK AT TIMES ALL LIGHTS ARE NOT FUNCTIONING CORRECTLY. LIGHTS AT TIMES TOO OFTEN WILL NOT WORK AT ALL. STABILITY WARNING LIGHT COMES OFTEN. AFRAID TRUCK WILL CATCH FIRE FROM THE ELECTRICAL ISSUES.. PLEASE HELP!!!!

MY WIFE WAS DRIVING 75 MPH ON THE INTERSTATE WHEN SHE HEARD A "DING" AND THE INFORMATION CENTER SAID "SERVICE STABILITY" "ENGINE POWER REDUCED" IT THEN TOOK ALL ENGINE POWER FROM THE VEHICLE IMMEDIATELY CAUSING IT TO SLOW TO A VERY UNSAFE 20 MPH ALMOST INSTANTLY AND CAUSED HER TO NARROWLY AVOID BEING HIT FROM BEHIND. THIS HAPPENED SEVERAL MORE TIMES. WE TOOK THE VEHICLE IN FOR SERVICE AND WERE TOLD WE NEEDED A NEW THROTTLE BODY CABLE WHICH WE BOUGHT AND HAD THEM INSTALL, BUT THE PROBLEM HAS NEVER GONE AWAY. I HAVE READ MANY MANY COMPLAINTS ABOUT THIS ON THE INTERNET BUT AFTER YEARS OF COMPLAINING NOTHING HAS BEEN DONE. DOES SOMEONE HAVE TO DIE BEFORE SOMETHING IS DONE? IT CERTAINLY SEEMS LIKE IT. I FILED A COMPLAINT WITH THE GOVERNMENT SEVERAL YEARS AGO ABOUT THIS ISSUE AND I AM SURE MANY OTHERS HAVE AS WELL. NOTHING HAS EVER BEEN DONE. TO CAP IT OFF, AND THE REASON I AM ON THIS AGAIN, IS BECAUSE THIS PAST WEEKEND I RENTED A BUICK ENCLAVE FROM BUDGET RENTAL CARS IN LITTLE ROCK ARKANSAS. THIS WAS A NEW VEHICLE THAT HAD ONLY 5 MILES ON IT WHEN I LEFT THE LOT. AT AROUND 65 MILES LATER THE VEHICLE DID THE SAME EXACT THING, AND REDUCED MY SPEED TO 25 WITH AN 18 WHEELER BEHIND ME THAT HAD TO SWERVE TO MISS ME AS I SWERVED TO THE SHOULDER TO GET OUT OF THE WAY. PLEASE DO SOMETHING BEFORE SOMEONE IS KILLED!!! *TR

MY DAUGHTER WAS DRIVING AND WHEN SLOWING DOWN THE BRAKES FAILED TO WORK. THE VEHICLE WAS NOT ABLE TO STOP AND COLLIDED WITH THE VEHICLE IN FRONT. LUCKILY NOBODY WAS INJURED IN THIS COLLISION. AFTER INSPECTION, I NOTICED FLUID ON THE GROUND AT THE REAR LEFT (DRIVER'S SIDE REAR), AND LOOKED UNDER THE VEHICLE TO SEE WHERE THE FLUID MAY BE COMING FROM. I SAW THAT THERE WAS FLUID COATING A LARGE AREA OF THE UNDERBODY, AND ALSO SEE THE BRAKE LINE ATTACHED TO THE FRAME AS WET AND RUSTED. I HAVE PICTURES SAVED AS A REFERENCE. *TR

Crash

TL* THE CONTACT OWNS A 2003 GMC YUKON DENALI. THE CONTACT STATED THAT THE VEHICLE DECELERATED AND STALLED. THE REDUCED ENGINE POWER INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO THE DEALER SIX TIMES TO REPAIR THE THROTTLE BODY, PEDAL SWITCH, AND WIRING HARNESS, BUT THE FAILURE RECURRED. THE FAILURE MILEAGE WAS 220,000. UPDATED 10/02/14*LJ UPDATED 3/9/2015 *JS

WE HAVE A 2003 YUKON THAT WILL SHUTS DOWN ANYWHERE AND ANYTIME, THE FOLLOWING EXAMPLE HAS HAPPENED MORE THAN ONCE. WE WERE DRIVING ON THE HIGHWAY WHEN "REDUCED ENGINE POWER" "STABILITY TRACTION LOSS" APPEARED ON DISPLAY - I PRESSED THE ACCELERATOR AND THE VEHICLE WOULD NOT MOVE. I HAD TO COMPLETELY SHUT DOWN THE ENGINE WAIT A FEW MINUTES THEN RESTART IN ORDER FOR THE VEHICLE TO OPERATE CORRECTLY AND A COUPLE MILES DOWN THE ROAD, IT HAPPENED AGAIN. IT WAS A SNOWY MESS OUT SIDE WHICH MADE THE SITUATION WORSE. THIS IS A MAJOR SAFETY CONCERN AS I AM UNABLE TO ACCELERATE IN ORDER TO AVOID AN ACCIDENT. I GET SCARED BECAUSE THERE COULD BE A SEMI BEHIND US AND IT WILL JUST PLOW INTO US BECAUSE WE CAN NOT DO ANYTHING UNTIL WE SHUT DOWN THE ENGINE AND RESTART. VERY SCARY. WE RESEARCHED THIS ISSUE TO FIND OTHER PEOPLE ARE IN THE SAME SITUATION AND NO ONE SEEMS TO KNOW HOW TO FIX IT. THIS IS A LONG STANDING ISSUE, GM IS AWARE OF THIS ISSUE BUT WILL NOT ISSUE A RECALL. GM SEEMS TO BE HAVING ALOT OF PROBLEMS THAT THEY ARE NOT DEALING WITH. SHAME ON GM! *TR

ENGINE LEAKING OIL REAR CRANK SEAL AND PLATE. GMC SAID SEAL WILL NOT BE ENOUGH, NEED TO REPLACE PLATE. DEFECTIVE. MY MECHANIC CHARGED ME $710.41. GMC SHOULD BE REIMBURSING ME. *TR

DRIVING ALONG WHEN ALL OF A SUDDEN I NEEDED TO BRAKE FOR CURVE AND THE BRAKE PEDAL WENT DOWN TO THE FLOOR. I RAN OFF INTO A GRASSY FIELD TO PREVENT A SERIOUS INJURY. *TR

Crash

DRIVING ON HWY GOING APRX 65MPH. VEHICLE SAID REDUCED ENGINE POWER AND STARTED SLOWING DOWN. I HAD TO PULL TO SIDE OF THE ROAD. I MANAGED NOT TO BE REAR ENDED. THIS HAS HAPPENED OFTEN. IT IS A POTENTIALLY LIFE THREATENING SITUATION. GMC KNOW ABOUT THIS PROBLEM AND HOW DIFFICULT IT IS TO FIND THE PROPER FIX. SOMEONE IS GOING TO DIE DUE TO THEIR LACK OF ACTION. IT'S NOT SAFE. *TR

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.

THE SERVICE ENGINE LIGHT AND TRACTION CONTROL TURN ON AND THE INFORMATION CENTER ON MY CLUSTER READS "ENGINE POWER REDUCED" AND "STABILITY SYSTEM DISABLE", THEN MY SPEED IS REDUCED AND ONLY RUNS BETWEEN TEN AND TWENTY MILES PER HOUR. I HAVE TO TURN OFF MY TRUCK AND TURN IT BACK ON AFTER A FEW MINUTES TO CONTINUE, BUT THIS PROBLEM HAS HAPPENED ON A DAILY BASIS. I THINK GMC IS RESPONSIBLE FOR THIS AND MORE SIMILAR PROBLEMS. *TR

I WAS DRIVING APPROXIMATELY 65 MPH UPHILL WHEN MY ENGINE AND TRACTION LIGHT CAME ON. MY SPEED WAS IMMEDIATELY REDUCED TO ABOUT 35 MPH EVEN THOUGH I TRIED TO ACCELERATE. I DROVE HOME ABOUT 8 MILES AT A REDUCED SPEED BECAUSE I HAD MY CHILDREN IN THE TRUCK AND IT WAS RAINING. I TOOK THE TRUCK TO A MECHANIC THE NEXT DAY AND HE REPLACED THE THROTTLE BODY. I PICKED UP THE TRUCK THAT EVENING AND AS I WAS DRIVING HOME THE SAME THING HAPPENED AGAIN. I TOOK THE TRUCK BACK TO THE MECHANIC, THE CHECK ENGINE LIGHT AND TC LIGHT WAS ON AGAIN HOWEVER HE SAID THAT THERE WAS NOTHING WRONG. HIS THOUGHT WAS TO REPLACE THE THROTTLE BODY AGAIN. TWO REPLACEMENTS LATER, THE PROBLEM REMAINS. *TR

I WAS DRIVING HOME AT NIGHT AFTER GETTING GAS IN THE MIDDLE OF THE GAS SHORTAGE DURING THE MAJOR SNOW STORM IN THE NORTH EASTERN UNITED STATES. AS I WAS APPROACHING A LIGHT I PRESSED ON THE BRAKES AND IT WENT STRAIGHT TO THE FLOOR. I THEN BROUGHT IT TO A MECHANIC AND WHEN IT WAS PLACED ON A LIFT THEY NOTICED THE ENTIRE BOTTOM OF THE CAR WAS RUSTED INCLUDING THE BRAKE LINES. THEY ENDED UP REPLACING THE ENTIRE BRAKE LINE SYSTEM DUE TO EXCESSIVE RUST. *JS

AFTER STEPPING ON MY BRAKES AGGRESSIVELY TO STOP FOR A DOG CROSSING THE ROAD. I RECEIVED A BRAKE STABILITY NOTICE ON MY DASH. SINCE I WAS IN THE MIDDLE OF THE ROAD, I PUT THE CAR INTO DRIVE TO GET OVER TO THE SIDE OF THE ROAD. THE CAR DID NOT SLOW DOWN AFTER I PUMPED THE BRAKES, AND TRIED TO THROW THE CAR IN REVERSE TO REDUCE THE SPEED. I COASTED INTO A PARKED SUBARU ON THE SIDE OF THE ROAD AND BECAUSE OF THE REAR IMPACT THE SUBARU THAT I HIT PUSHED INTO TOYOTA HIGHLANDER IN FRONT OF IT. THEREFORE THREE CARS AFFECTED BY THE ACCIDENT. MY CHILDREN WERE IN THE CAR WITH ME AND THAT WAS THE WORST PART, I WOULD HAVE COASTED RIGHT INTO A BUSY INTERSECTION ON MAIN STREET HAD I NOT STOPPED THE WAY THAT I DID. AFTER TAKING THE TRUCK TO MY MECHANIC HE MENTIONED THAT I POPPED TWO BRAKE LINES. *TR

Crash

I WAS TRAVELING DOWN A CITY STREET AND WENT TO STOP AT A RED LIGHT. I APPLIED THE BRAKES AND THE PEDAL WAS VERY SOFT SO I PUSHED A LITTLE HARDER AND THE PEDAL WENT TO THE FLOOR. I HAD TO SWERVE INTO A GAS STATION PARKING LOT TO AVOID AN ACCIDENT AND APPLY THE EMERGENCY BRAKE TO STOP THE VEHICLE. I CRAWLED UNDER THE VEHICLE AND SAW THAT THERE WAS BRAKE FLUID DRIPPING FROM THE FLOOR AND THE HARD LINES UNDER THE DRIVER SIDE FLOOR. IT IS GETTING TAKEN TO THE DEALER TONIGHT TO HAVE THE ISSUE FIXED. PLEASE MAKE GM RESPONSIBLE FOR THIS ISSUE AND TO PAY US BACK AS THIS IS A VERY DANGEROUS PROBLEM AND VERY EXPENSIVE TO FIX. IF I WOULD HAVE HIT THE BRAKE A COUPLE SECONDS LATER I WOULD HAVE MISSED THE ENTRANCE TO THE GAS STATION AND REAR-END THE VEHICLE IN FRONT OF ME. *TR

I HAVE A 2003 GMC YUKON DENALI, IT RECENTLY BEGIN A SKIPPING LIKE MOTION ON THE SPEEDOMETER. THEN AFTER ABOUT A WEEK IT STARTED READING OFF BY ABOUT 30 MPH NOW WHEN DRIVING ITS SITS AT ZERO 90 PERCENT OF THE TIME, THE OTHER 10 PERCENT OF THE TIME IT STAY AT 15 MPH NO MATTER HOW FAST OR SLOW I AM MOVING. *TR

THE SEAT BELTS IN MY 2003 GMC YUKON DENALI KEEP COMING UNBUCKLED. NO MATTER HOW MANY I REPLACE. ALSO I'VE HAVE A PROBLEM WITH THE TRACTION CONTROL COMING ON. IT'S ALMOST CAUSED A COUPLE OF ACCIDENTS. I'VE TAKEN THE VEHICLE TO THE GMC DEALERSHIP AND THEY'VE INFORMED ME THAT THEY'VE COME ACROSS THIS ISSUE A NUMBER OF TIMES AND HAVE NEVER FIXED THE ISSUE AND TO JUST TAP MY GAS PEDAL TWICE TO TAKE THE VEHICLE OUT OF THE TRACTION CONTROL. *TR

TL* THE CONTACT OWNS A 2003 YUKON DENALI. THE CONTACT STATED THAT THE ENGINE WAS STARTED AND BOTH THE DRIVER AND PASSENGER SIDE FRONTAL AIR BAGS DEPLOY INADVERTENTLY. THE VEHICLE WAS NOT TAKEN TO THE DEALER TO HAVE A DIAGNOSTIC PERFORMED. THE VEHICLE WAS NOT REPAIRED. THE CONTACT WAS NOT INJURED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE CURRENT AND FAILURE MILEAGE WAS 113,000.

RUSTED BRAKE LINES CAUSED IMMEDIATE LOSS WITH NO WARNING. LOSS OF BRAKES WERE CATASTROPHIC WITH ONLY EMERGENCY BRAKES AVAILABLE. CAR CAME TO A CONTROLLED STOP ON MEDIAN BUT COULD OF BEEN MUCH WORSE GIVEN NO OTHER VEHICLES IN THE VICINITY. *TR

BRAKE LINE BURST WHILE UNDER A HARD BRAKING SCENARIO. FURTHER INSPECTION REVEALED ALL LINES UNDER AND UP TO THE PROPORTIONING VALVE ARE ALL ROTTING TO THE POINT OF NEEDING TO BE REPLACED. *TR

TL* THE CONTACT OWNS A 2003 GMC YUKON DENALI. THE CONTACT STATED THAT WHILE DRIVING 20 MPH, SHE ATTEMPTED TO BRAKE BUT THE VEHICLE DID NOT BRAKE. THE CONTACT HAD TO REMOVE HER FOOT FROM THE BRAKE PEDAL TO STOP THE VEHICLE. THE FAILURE OCCURRED WITHOUT WARNING. THE VEHICLE WAS THEN TOWED TO THE DEALER. THE DEALER STATED THAT THEY NEEDED TO REPLACE THE BRAKE LINES. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE AND CURRENT MILEAGES WERE 120,000.

TL* THE CONTACT OWNS A 2003 GMC YUKON DENALI. THE CONTACT WAS DRIVING 60 MPH WHEN ALL OF THE GAUGES ON THE INSTRUMENT PANEL BECAME STUCK AND SOME WERE PROVIDING INACCURATE READINGS INCLUDING THE FUEL GAUGE AND THE SPEEDOMETER. THE VEHICLE WAS TAKEN TO THE DEALER BUT WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE 90,000.

OFF AND ON SINCE LAST YEAR I HAVE HAD PROBLEMS WITH MY ELECTRICAL SYSTEM. JUST OUT OF THE BLUE THE CHECK ENGINE LIGHT WILL COME ON AND THE "REDUCE ENGINE SPEED" MESSAGE WILL SHOW UP ON THE DASHBOARD. AND MY SPEED WILL SHUT DOWN AND THE VEHICLE WILL ONLY GO ABOUT 25MPH. WE HAD TAKEN IT IN TO A SHOP AND THEY WERE UNABLE TO FIND THE ISSUE AND SAID IT WAS JUST A LOW BATTERY. WELL AFTER REPLACING THE BATTERY IT CONTINUES TO DO THIS OFF AND ON. ONCE THE CAR IS SHUT OFF AND RESTARTED IT WOULD BE FINE UNTIL THE NEXT INCIDENT. NOW WHILE DOING RESEARCH ON THIS ISSUE I HAVE READ THAT MANY PEOPLE ARE HAVING THIS PROBLEM. SOME PEOPLE HAVE EXPERIENCED THIS WHILE ON THE FREEWAY GOING 65MPH. THE ENGINE WILL JUST REDUCE SPEED AUTOMATICALLY. WHY IS THIS NOT A RECALL FOR SAFETY REASONS? WHAT HAS TO BE DONE FOR THERE TO BE A RECALL ON THIS ISSUE?

TL* THE CONTACT OWNS A 2003 GMC YUKON DENALI. THE CONTACT STATED THAT WHILE DRIVING 20 MPH, THE BRAKES WERE APPLIED AND FAILED AND THE BRAKE PEDAL WAS DEPRESSED INTO THE FLOORBOARD. THE CONTACT HAD TO UTILIZE THE EMERGENCY BRAKE AND THE VEHICLE WAS TOWED TO A LOCAL MECHANIC. THE MECHANIC DISCOVERED THAT THE BRAKE LINE WAS RUSTED AND LEAKING BRAKE FLUID. THE MECHANIC REPAIRED THE ENTIRE BRAKE LINE AND MASTER CYLINDER. THE CONTACT DID NOT CALL THE MANUFACTURER. THE FAILURE MILEAGE WAS 78,000. THE VIN WAS NOT AVAILABLE.

WE WERE DRIVING AT HIGHWAY SPEED AND LOST POWER WITH NO WARNING. I COASTED TO THE SIDE OF THE HIGHWAY AVOIDING ONE COLLISION. I HAD IT TOWED BACK TO HOME. THE DEALER HAD TO CLEAN THE THROTTLE BODY. I CONTACTED GM AND ASKED WHERE WAS THIS CLEANING FOR PREVENTIVE MAINTENANCE. THEY COULD NOT ANSWER. I AM FEARFUL FOR OTHERS WHO HAVE THIS TYPE OF VEHICLE. WITHOUT CLEANING THE THROTTLE BODY OTHERS WILL HAVE THIS PROBLEM TOO. I WENT TO SEVERAL INTERNET FORUMS AND MANY OTHERS HAVE STATED THIS PROBLEM. HTTP://TOWNHALL-TALK.EDMUNDS.COM/DIRECT/VIEW/.F0E807E/227 PLEASE HELP! [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

TOTAL BRAKE FAILURE AFTER A LONG TRIP. *TR THE CONSUMER STATED THE BRAKE FAILURE WAS A RESULT OF RUSTED BRAKE LINES. UPDATED 05/08/12

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
