WITHOUT WARNING THE BRAKES FAILED. VEHICLE WAS IN MOTION AT TIME OF FAILURE, VEHICLE COULD NOT BE STOPPED AND AT 30 MPH RAN THROUGH THE RED TRAFFIC LIGHT AT A BUSY CITY INTERSECTION. FORTUNATELY, NO ACCIDENT OCCURRED. VEHICLE HAD TO BE TOWED TO DEALERSHIP. DEALER REPAIRED VEHICLE. INVOICE STATED: "BRAKE LINE WORE THROUGH FROM STEERING COLUMN RUBBING ON FLEXIBLE SECTION."
STEEL BRAKE LINES HAVE RUSTED THROUGH, CAUSING LEAKAGE AND TOTAL BRAKE FAILURE DURING APPLICATION. CALIPERS AND BLEEDER VALVES ALSO RUSTED, PREVENTING NEW BRAKE LINES FROM BEING RE-ATTACHED.
WHILE OPERATING THE VEHICLE ON A HIGHWAY I PRESSED THE BRAKE PEDAL AND SUDDENLY THE BRAKE PEDAL SUNK AND I LOST BRAKES. I NEARLY LOST CONTROL OF THE VEHICLE AND ALMOST DROVE INTO A GUARD RAIL. AFTER FURTHER INSPECTION I OBSERVE THE FRONT DRIVERS SIDE BRAKE WAS CORRODED CAUSING IT TO BREAK. THIS APPEARS TO BE AN ISSUE WITH GMC AND THE COMPANY SHOULD BE REQUIRED TO RECTIFY THE SITUATION. USING STAINLESS WOULD PREVENT INCIDENTS LIKE THESE AND POSSIBLE INJURIES OR DEATHS.
TL* THE CONTACT OWNS A 2004 GMC YUKON DENALI XL. THE CONTACT STATED THAT WHEN THE ACCELERATOR PEDAL WAS DEPRESSED DURING ACCELERATION, THE VEHICLE HESITATED AND THE TRACTION ACTIVE WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE AIR FILTER FAILED AND NEEDED TO BE REPLACED, THE BG FUEL INDUCTION SERVICED NEEDED TO BE DONE, THE FRONT BRAKE PADS AND ROTORS FAILED AND NEEDED TO BE REPLACED, AND THE REAR DIFFERENTIAL SERVICE NEEDED TO BE DONE. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 40,000.
DRIVING AT 35 MPH WHEN THE BRAKES SUDDENLY STOPPED WORKING WITH NO INDICATION PRECEDING INCIDENT. VEHICLE MADE CONTACT WITH CURB BEFORE COMING TO A COMPLETE STOP. DISCOVERED REAR BRAKE LINES HAD COMPLETELY CORRODED THROUGH AND VEHICLE WAS LOSING FLUID. APPARENTLY THIS IS A KNOWN PROBLEM THAT GM REFUSES TO FIX. *TR
HAD JUST BACKED OUR BAY BOAT INTO IT'S SPOT AFTER HAULING IT ON I95,THE BLUE ROUTE AND PA TURNPIKE .WHEN I RELEASED THE EMERGENCY BRAKE TO PULL AWAY FROM THE BOAT,THE SERVICE BRAKE LIGHT APPEARED,AND IMMEDIATELY LOST MOST OF MY BRAKING POWER .I FOUND THAT ONE OF THE BRAKE LINES HAD RUPTURED .IF THIS HAD HAPPENED ON THE HIGHWAY ,TOWING THE BOAT,IT WOULD HAVE BEEN CATASTROPHIC. I DIDN'T REALIZE HOW COMMON A PROBLEM THIS HAS BEEN UNTIL I FOUND UNTOLD NUMBERS OF OTHER OWNERS ON THE WEB WITH THE SAME ISSUE. *TR
THE BRAKE TUBING MOUNTED ALONG THE FRAME TOWARDS THE ABS AND AWAY FROM THE ABS ARE VERY RUSTED FLAKING ETC. THEY HAVE NOT BUSTED JET BUT COULD ANY MOMENT, I'M HAVING THEM CHANGED. AS MANY PEOPLE HAD BUSTED TUBING FOR ME IT IS A SAFETY ISSUE, I'M AN MECHANICAL ENGINEER AND I UNDERSTAND THE DEFECT. *TR
A VEHICLE IN FRONT OF ME STOPPED SHORT BECAUSE A CAR WAS MAKING A LEFT TURN IN FRONT OF HIM. I APPLIED THE BRAKES. I WAS ABLE TO STOP BUT IMMEDIATELY THERE WAS A WHITE SMOKE COMING FROM UNDER THE HOOD AND THE TRACTION CONTROL AND BRAKE LIGHTS CAME ON. I WENT TO DRIVE A FEW FEET AND TRIED TO STOP WHEN I REALIZED I HAD NO BRAKES AT ALL AND THE WHITE SMOKE WAS STILL COMING OUT. MY VEHICLE WAS TOWED TO A SHOP. THE BRAKES LINE FAILED BECAUSE OF CORROSION. THE BRAKE FLUID WAS SPRAYING ONTO THE EXHAUST MANIFOLD CREATING THE WHITE SMOKE. *TR
DUE TO CORRODED BRAKE LINES, MY BRAKES FAILED, CAUSING A CRASH. *TR
WAS PARKED ON A HILL, WHEN PULLING AWAY THE BRAKE PEDAL WENT TO THE FLOOR BUT PROVIDED ALMOST NO BREAKING POWER. A FEW MOMENTS LATER, MULTIPLE BEEPS OCCURRED WITH MESSAGES APPEARING ON DASH DISPLAY (AFTER THE FAILURE), ABOUT BRAKE SYSTEM NEEDS CHECKED OR SERVICED, AND STABILITY SYSTEM DISABLED. TO CATCH THE LEAKING FLUID, I PLACED THE PAN UNDER THE DRIVER'S SEAT AREA. LINES LOOKED TOTALLY RUSTED. *TR
BRAKE LINE FAILURE DUE TO CORROSION. *TR
I HAD BEEN DRIVING ON THE EXPRESSWAY, I EXITED AND STOPED AT A DRIVE UP WINDOW. AS I PULLED UP TO THE WINDOW MY BRAKE PEDDLE WENT TO THE FLOOR, I HAD TO PUT IT IN NEUTRAL AND USE THE EMERGENCY BRAKE TO GET THE CAR TO STOP. AFTER INSPECTION I FOUND THAT A LINE WITHIN THE CLUSTER OF FOUR HAD FAILED UNDER THE DRIVERS SIDE FRONT DOOR. ALL THE LINES NEEDED TO BE REPLACED DUE TO SEVERE RUST. *TR
THE BRAKE LIGHT CAME ON IN MY CAR AND WHEN I TOOK IT IN TO THE MECHANIC, I WAS TOLD THE BRAKE LINES WERE CORRODED. BRAKE FLUID WAS LEAKING THROUGH THE LINES AND IF I HAD DRIVEN FOR EVEN ANOTHER HOUR, I WOULD HAVE HAD NO BRAKES. I HAD THE LINES REPLACED, WHICH HAD TO BE CUSTOM BUILT. THE REPAIR COST ME $1188. *TR
HARD BRAKE LINES ON FRAME UNDER DRIVERS DOOR RUSTED THROUGH CAUSING BRAKE FAILURE. WHILE DRIVING STEPPED ON BRAKES AND BRAKE PEDAL WENT ALL THE WAY DOWN TO THE FLOOR AND VEHICLE WOULD NOT STOP. NOTICED BRAKE FLUID LEAKING FROM UNDER DRIVERS DOOR AND SAW THAT THE HARD BRAKE LINES ON THE FRAME WERE RUSTED THREW. I HAD LOTS OF OLDER VEHICLES AND NEVER HAD THE HARD BRAKE LINES RUSTED THREW ESPECIALLY IN A 9 YEAR OLD VEHICLE. COULD HAVE BEEN VERY SERIOUS ACCIDENT IF IT HAD HAPPENED ON A HIGHWAY. *TR
EXCESSIVE RUST BUILD UP ON BRAKE LINES, ROTORS AND CALIPERS. ROTORS & PADS PREVIOUSLY REPLACED IN SEPT., 2008. NEEDED REPLACEMENT AGAIN IN OCT., 2012 AFTER ONLY DRIVING 16,000 MILES. BRAKE LINES ARE SEVERELY CORRODED AND ARE IN NEED OF REPLACEMENT. CONTROL ARM LINKAGE ATTACHED TO HEIGHT SENSOR ACTUATOR ALSO BROKE AT ABOUT THE SAME TIME. *TR
TL* THE CONTACT OWNS A 2004 YUKON DENALI XL. THE CONTACT STATED THAT FLUID WAS LEAKING FROM THE HYDRAULIC BRAKE BOOSTER AND THE RELEASE VALVE. THE VEHICLE ALSO EMITTED A LOUD NOISE WHEN IT WAS STARTED. THE CONTACT TOOK THE VEHICLE TO AN INDEPENDENT MECHANIC, WHO INSPECTED THE BRAKES AND INFORMED THE CONTACT THAT THE HYDRAULIC BRAKE BOOSTER AND THE RELEASE VALVE NEEDED TO BE REPLACED.

THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 189,000.. UPDATED 05/17/12 *BF UPDATED 05/23/12.*JB

AS I WAS DRIVING HOME FROM WORK LATE THIS AFTERNOON ON JULY 05, 2011 ON RT 589 IN PASCO COUNTY FL, I WAS COMING OFF THE EXIT TO A RED LIGHT AND I COULD NOT STOP. I HAD TO PUSH THE BRAKE PEDAL TO THE FLOOR AND HOLD IT THERE IN ORDER TO STOP JUST SHORT OF THE INTERSECTION. LUCKILY THERE WERE NO CARS IN THE RIGHT LANE GOING THROUGH THE INTERSECTION AT THE SAME TIME. I PULLED OVER AFTER THE LIGHT TURNED GREEN AND NOTICED FLUID SQUIRTING OUT ABOVE THE PASSENGER REAR TIRE AREA. AFTER I MADE IT HOME I PULLED THE TIRE OFF AND LOOKED AROUND AND NOTICE TWO HEAVILY CORRODED LINES WHERE THE FLUID WAS COMING OUT.
MY 2004 YUKON THE PANEL WITH THE SPEED CONTROL STARTED DISAPPEARING. THEN IT WOULD COME BACK ON THEN DISAPPEAR AGAIN. NOW IT DON'T WORK AT ALL. I CANT TELL THE GAS AMOUNT, SPEED OR MILES. THE STABILITY LIGHT USE TO COME ON. *TR
