2003 GMC Yukon Denali XL

THE CLUSTER FROM ALL THE DASHBOARD HAS STOP WORKING THE SPEEDOMETER THE GAUGES EVERYTHING

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.

I LET MY FREIND TAKE VEHICLE AND SHE SAID WHEN SHE BRAKED THE PEDAL WENT TO FLOOR.SHE WAS HALF MILE AWAY AND MADE IT BACK .I LOOKED AT LEVEL IN MASTER CYLINDER AND HAD TO PUT FLUID IN.NOTICED BRAKE FLUID ON THE UNDERCARRIGE WHICH LED ME TO RUSTED BRAKE LINE UP FRONT.

I WAS DRIVING WITH MY 14MONTH OLD BABY IN THE CAR AND ALL OF A SUDDEN I HAD NO BRAKES AT ALL. MY PARKING BRAKE COULDN'T STOP ME EITHER SO I PUT THE CAR IN NEUTRAL AND THEN FORCED IT INTO PARK SO I DIDN'T CRASH. THE BRAKE LINES ARE COMPLETELY CORRODED AND I DIDN'T HAVE ANY NOTICE OR IDEA UNTIL THE BRAKES WERE ALREADY GONE.

JUST BOUGHT CAR ELECTRICAL HAS BEEN ACTING UP FOR A WHILE NOW (30 DAYS) AND NOW DASH HAS GONE OUT SUNROOF WONT OPEN PR CLOSE AND DRIVER SIDE PASSENGER WINDOW DOESNT WORK AUTO STORE WONT FIX OR TAKE BACK CAR

A DOG RAN OUT IN FRONT OF ME I APPLIED MY BRAKES AND THE PEDAL WENT TO THE FLOOR HAD IT CHECKED AT BALE CHEVROLET IN LITTLE ROCK ARK. WANTED TO CHARGE ME 6800.00 TO REPAIR HAD IT TOWED BACK TO IL. WHERE I LIVE THAT COST WAS 500.00 BESIDES 200 MILES THAT WAS COVERED BY AAA I,M A 62 YR OLD WOMAN HAD MY GRANDCHILDREN WITH ME IN LITTLE ROCK ARK THIS EXPERIENCE WAS THE SCARIEST TIME IN MY LIFETIME NO WARNING JUST ALL OF A SUDDEN NO BRAKES IN THE WORST TRAFFIC EVER. THE MONEY SPENT ON THIS TRIP WAS VERY EXPENSIVE NOT TO MENTION THE STRESS. *TR

VEHICLE WENT INTO REDUCED ENGINE POWER AND STABILTRAK WARNING LIGHT CAME ON. REDUCED SPEED FROM 60 TO 10MPH. NOW OCCURS ON A REGULAR BASIS. *TR

BRAKE PIPE BLEW OUT FROM CORROSION... LIGHT FRONT DAMAGE TO GMC AND REAR END DAMAGE TO CAR IN FRONT FROM LACK OF BRAKING POWER. *TR

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

THE PROBLEM: BRAKES FAILED WHILE VEHICLE WAS RUNNING. AFTER A HARD BRAKE AT A STOPLIGHT AND DRIVING BRIEFLY, THE BRAKE PEDAL WENT STRAIGHT TO THE FLOOR BARELY STOPPING THE VEHICLE. BRAKES WERE EXTREMELY MUSHY TO NON-EXISTENT AT TIMES. REPAIR WORK: LOCAL GMC SERVICE DEPARTMENT INDICATED THE BRAKE LINE HAD RUSTED OUT AND THEY REPLACED IT FOR CLOSE TO $1,600. PER THE INVOICE REPAIRS INCLUDED: BRAKE SYSTEM REPAIR/LABOR, BRAKE FLUSH KIT, PIPE KIT AND FLUID. (WHEN ASKED ABOUT BRAKE LINE ISSUES LATER, THE DEALERSHIP STATED THEY HAVE NEVER HEARD OF ANY PROBLEMS REGARDING THEM WITH GMCS.) HOW IT HAPPENED: WHILE DRIVING WITH MY WIFE AND CHILDREN IN THE VEHICLE, I HAD TO BREAK HARD WHEN I CAME AROUND A BEND TO A RED STOPLIGHT. THOUGH THE BRAKES WORKED, THEY FELT LIKE THEY WERE GIVING JUST A LITTLE AFTER I FINALLY CAME TO A STOP. WE PRECEDED ANOTHER 15-MILES WITH NO INCIDENT AND PULLED INTO RESTAURANT DRIVE-THRU. WHILE SITTING IN THE DRIVE-THRU LANE WITH THE VEHICLE IN GEAR AND MY FOOT ON THE BRAKE, ALL OF A SUDDEN MY FOOT WENT TO STRAIGHT TO THE FLOOR AND THE VEHICLE JUMPED FORWARD. THANKFULLY THERE WAS ENOUGH SPACE BETWEEN MY VEHICLE AND THE VEHICLE IN FRONT OF ME SO THAT I DIDN' HIT THEM. I IMMEDIATELY SHIFTED IT OUT OF GEAR TO STOP THE VEHICLE FROM MOVING FORWARD. AT THIS TIME I NOTICED A WARNING LIGHT HAD COME ON INDICATING TO CHECK BRAKES AND THAT THE ABS WAS OFF. I TESTED THE VEHICLE IN A NEARBY EMPTY PARKING LOT TO SEE IF IT WAS STILL DRIVABLE AND THE BRAKES APPEARED TO HAVE ONLY

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

THE BRAKE LINES ON THE ENTIRE VEHICLE WERE FOUND TO BE SEVERELY RUSTED AFTER THE REAR LINES BURST WHILE ATTEMPTING TO STOP FROM 25 MPH. *TR

HAVE A 2003 YUKON DENALI AND WHEN IT HIT THE 131000 MILES MARK THE FUEL GAUGE STOPPED WORKING LEAVING ME TO TELL HOW MUCH GAS I HAD LEFT USING THE AUTOMATIC COMPUTER TELLING YOU HOW MANY MILES TO EMPTY. NEXT THE OIL GAUGES STOPPED WORKING. MY SPEEDOMETER QUITE WORKING LEAVING ME TO NOT KNOWING THE SPEED I AM TRAVELING THIS QUITE WORKING WHILE I WAS DRIVING DOWN A HIGHWAY. TO MAKE MATTERS WORSE MY RPMS ARE STARTING TO GO GOOFY WHICH MEANS THAT TO IS GOING TO STOP WORKING AS WELL. I WAS TOLD THAT HAVING MY DASH TAKEN OFF AND FIXED COULD RUN ANYWHERE BETWEEN 700$ NOT INCLUDING LABOR FEES. WHICH IS CRAZY THAT GMC DOESN'T STAND BEHIND ITS WORK. PEOPLE CANT AFFORD TO BE PAYING FOR THIS TO GET FIXED LET ALONE SPEEDING TICKETS. I BELIEVE SOMETHING NEEDS TO BE DONE AFTER READING ABOUT SO MANY PEOPLE HAVE THIS SAME PROBLEM WITH THE ALL HAVING THE SAME YEAR YUKON DENALI.. YOU PAY ALL THIS MONEY FOR A VEHICLE AND SOMETHING LIKE THIS HAPPENS!!! *TR
