19 of the
97 complaints about the 2003 GMC Yukon Denali are about the
braking system — 20% of everything
reported for this model year.
Half of the failures with a mileage on record happened before
78,000 miles.
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)

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.

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.

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.

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.
