2003 GMC Yukon Denali Xl

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 A LITTLE BIT OF 'STOPPAGE' THOUGH THE PEDAL WAS TO THE FLOOR. I REALIZED IT TOOK 50-100 YARDS TO STOP THE VEHICLE WITH BRAKE FULLY PRESSED AND NO GAS WHEN WE WERE GOING 20-25 M/H. *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

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
