2004 GMC Yukon Denali Xl

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

THE INSTRUMENT PANEL GAUGES WILL JUST GO TO ZERO AS YOU'RE DRIVING DOWN THE ROAD. THEY MAY COME BACK ON IN A FEW MINUTES OR AFTER YOU SHUT DOWN THE VEHICLE. ALL FUSES ARE GOOD. ALL INDICATOR LIGHTS WORK I.E. TURN SIGNALS, HIGH BEAM, & HAZ. DURING RESTART THEY FLASH AS THEY WOULD NORMALLY BUT THE GAUGES MAY OR MAY NOT COME BACK ON LINE. AN INTERMITTENT PROBLEM.

THIS HAS OCCURRED SEVERAL TIMES SINCE THE INITIAL OCCURRENCE. AT VARIOUS SPEEDS (5-55 MPH) THE STEERING GOES OUT AND YOU CANNOT MOVE THE STEERING WHEEL. OUR VEHICLE HAS BEEN IN THE SHOP MULTIPLE TIMES OVER THE YEARS TO CORRECT THIS. THE MECHANICS CANNOT FIND ANYTHING WRONG, AND SINCE THIS IS NOT A CONTINUOUS PROBLEM, THEY ARE UNABLE TO EXPERIENCE IT. IT'S A FRIGHTENING EXPERIENCE WHEN YOU ARE ON THE BELTWAY AND NEED TO TAKE AN EXIT, OR FOLLOW THE BELTWAY BEARING RIGHT OR LEFT AND YOU HAVE NO CONTROL OF YOUR STEERING. MORE FRIGHTENING IS WHEN YOU HAVE YOUR CHILDREN IN THE VEHICLE. I'VE HAD ONE MINOR INCIDENT/ACCIDENT WHILE BACKING UP TO PARK MY TRUCK AT A CAMPGROUND. I DID NOT HAVE MY FOOT ON THE GAS AND WAS DRIFTING. THERE WAS A TREE BEHIND ME, WHICH I NEEDED TO PARK NEXT TO, AND THE STEERING WENT OUT AND MY LEFT BUMPER EDGE CAUGHT THE TREE, WHICH PUSHED THE BUMPER IN SLIGHTLY. THIS CAUSED THE RUBBER TRACK ON THE TOP OF THE BUMPER TO POP UP AND IT CANNOT BE REATTACHED. ADDITIONALLY THERE ARE NASTY SCRATCHES ON THE BUMPERS EDGE. *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

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 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 DEALER WAS NOTIFIED AND STATED THAT THERE WAS A RECALL ASSOCIATED WITH NHTSA CAMPAIGN ID NUMBER 05V043000 (SERVICE BRAKES, HYDRAULIC). THE VIN WAS NOT INCLUDED IN THE RECALL. 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
