  BRAKE LINE RUPTURE, 2003 GMC SIERRA 2500HD PICKUP. TOTAL LOSS OF BRAKING WHILE STOPPING FOR TRAFFIC AT 60 MPH. ALL LINES WERE ROTTED AND HAD TO REPLACED. CRASH WAS AVOIDED BECAUSE OTHER CARS REALIZED I HAD LOST BRAKING AND MOVED OUT THE WAY. DID NOT REPORT UNTIL NOW(DEC 2010) BECAUSE I THOUGHT IT WAS AN ISOLATED INCIDENT. NOW FINDING OUT THAT IT IS PREVALENT, SO MUCH, THAT I HAVE WARNED FRIENDS ABOUT IT AND AM FINDING IT TO BE QUITE COMMON. *TR

  I OWN A 2003 GMC SIERRA 1500 Z71 OFF ROAD TRUCK. I'VE HAD IT IN THE SHOP FOUR TIMES NOW DUE TO THE SAME PROBLEM. THE PROBLEM CONSISTS OF EXCESSIVE PLAY/BACKLASH IN THE REAREND/DIFFERENTIAL ACCORDING TO THE DEALER. THIS EXCESSIVE PLAY/BACKLASH IS CAUSING THE TRUCK TO JERK AFTER SHIFTING FROM FIRST TO SECOND AND SECOND TO THIRD GEARS. THE DEALER AND MANUFACTURER SAY THIS IS NORMAL ACCORDING TO GM SPECS. AT ONE POINT, WHILE SITTING AT A TRAFFIC LIGHT, I PROCEEDED TO ACCELERATE AFTER THE LIGHT TURNED GREEN AND THE TRUCK DIDN'T GO ANYWHERE, BUT AFTER A FEW SECONDS THE TRUCK SLAMMED INTO GEAR AND SPUN THE REAR TIRES. THIS PROBLEM SEEMS TO HAVE BEEN CORRECTED AFTER REPLACING THE TRANSMISSION CONTROL SOLENOID FOR NOW, BUT THE CONSTANT JERKING OF THE REAREND/DIFFERENTIAL SEEMS TO BE WORSENING. WHEN DISCUSSING THIS PROBLEM WITH THE DEALERS SERVICE MANGER AND NOW FINALLY WITH THE GENERAL MANGER, THEY STILL SAY THIS IS NORMAL AND HAS BEEN FOR ALL 2000 THROUGH 2004 GMC SIERRA'S. THAT'S INTERESTING, BECAUSE I OWNED TWO 2000 GMC TRUCKS IN THE PAST AND NEITHER ONE OF THEM EXPERIENCED THESE PROBLEMS.

  THE REAR BRAKE PADS SQUEALED & WERE GRINDING & THE TRUCK HAD VERY POOR STOPPING POWER. THE TRUCK WAS TAKEN TO MY MECHANIC & HE WAS DOING THE BRAKE JOB; HE REPLACED ALL FOUR ROTORS BECAUSE THEY WERE RUSTED BEYOND REPAIR. THE PADS WERE REPLACED AS WELL. WHILE HE WAS DOING THE BRAKES HE OBSERVED THE BRAKE LINES WERE RUSTED TO A POINT THAT IT ALARMED HIM & HE SAID THEY SHOULD BE CHANGED. HE ALSO COMMENTED THAT THE BRAKES HAD WORN VERY UNEVEN. THE FRONT PADS WERE BARELY WORN & WERE ONLY MAKING CONTACT AT A SMALL AREA OF THE ROTOR (ABOUT 1/2" OF THE FULL FACE ON THE ROTOR). THE BACK PADS & ROTORS WERE COMPLETELY WORN DOWN & THE ROTORS WERE RUINED. SOME OF THE AREAS UNDER THE TRUCK LOOK AS NEW & OTHER PLACES; MAINLY THE A-FRAMES, BRAKE LINES, SOME FRAME MEMBERS, ETC. LOOK LIKE THEY ARE 15 YEARS OR MORE OLDER. THE BRAKES WERE PUT BACK TOGETHER & NOW THEY ARE SO TIGHT & WON'T RELEASE THE ROTORS, CAUSING THE ROTORS TO OVER HEAT. I AM NOW HAVING HIM REPLACE THE BACK TWO CALIPERS WITH REPLACEMENT CALIPERS THAT USE PHENOLIC PISTONS RATHER THAN STEEL & ARE NOT GM PARTS. *KB

  BRAKE LINE FAILURE DUE TO EXCESSIVE CORROSION OF THE LINE. AFTER REPLACING THE LINE MYSELF, I PERFORMED A TEST RUN AND YET ANOTHER LINE FAILED DUE TO THE CORROSION PROBLEM. THE ISSUE HAS BEEN ADDRESSED BY GENERAL MOTORS IN CANADA, BUT HAS NOT BEEN ADDRESSED IN THE US. I FEEL THAT TEN YEARS AND ONLY 84,000 MILES IS NOT AN ACCEPTABLE TIMEFRAME/MILEAGE TO BE EXPERIENCING BRAKE LINE CORROSION FAILURE IN THE STATE OF VIRGINIA. IN FACT THE ENTIRE UNDERCARRIAGE OF THE VEHICLE IS CORRODED FAR WORSE THAN MY 2000 HONDA CIVIC WHICH HAS 175,000 MILES ON IT. GENERAL MOTORS SHOULD BE FORCED TO ADDRESS THE CORROSION ISSUES WITH THE SIERRA PICKUP LINE IN THE US. *TR

I MADE AN APPOINTMENT WITH MY MECHANIC AND HE FOUND THE BRAKE CALIPER WAS FROZE UP AND SHEARED OFF THE BRAKEPAD AND THIS RUINED THE BRAKE ROTOR, THIS OF COURSE CAUSED THE LOSS OF BRAKES ON THE RIGHT REAR SIDE, WHICH MUST HAVE BEEN PULLING ME OFF THE ROAD.

THE DEALERSHIP BELIEVED THIS FAILURE COULD BE RELATED TO THE WIRING HARNESS. SINCE THEY WERE UNABLE TO DUPLICATE THE PROBLEM NO REPAIRS WERE DONE. ALSO, THE VEHICLE STALLED AT VARIOUS SPEEDS WITHOUT WARNING. WHILE THE STALLING OCCURRED THE CONTACT PRESSED HARD ON THE BRAKES TO ELEVATE THE STALLING. HE BELIEVED THIS WAS DUE TO THE POWER BRAKES.

  I HAVE A 2003 GMC SIERRA AND THE SPEEDOMETER IS STUCK AT 45-60 MPH, AND GOES UP PAST THE 120 MPH MARK WHEN IN MOTION. I BELIEVE THIS IS A SERIOUS SAFETY HAZARD, AND FROM A SEARCH ONLINE, I FOUND THAT THIS PROBLEM IS FOUND ON MANY OTHER 2003-2006 GM TRUCKS. THIS NEEDS TO BE RECALLED IMMEDIATELY DUE TO EXPIRED WARRANTIES FOR MANY OTHER GM TRUCK OWNERS THAT HAVE THIS FAULTY SPEEDOMETER PROBLEM, AND THE EXPENSIVE COST TO REPAIR/REPLACE. THANK YOU. *JB

  THE ABS ACTIVATES AT LOW SPEED BRAKING UNDER DRY ROAD CONDITIONS WITHOUT THE TIRES LOCKING UP. THE BRAKE PEDAL VIBRATES AS IF I WERE ON ICE WITH THE TIRES LOCKED UP. BRAKING EFFECT IS REDUCED UNDER THESE CONDITIONS. THIS HAPPENS RANDOMLY AND WHEN IT DOES I CANNOT BE SURE IF I CAN STOP IN TIME BEFORE HITTING THE VEHICLE OR OBJECT IN FRONT OF ME.

  WHILE HAVING MY VEHICLE CHECK OVER FOR THE WINTER, THE MECHANIC INFORM ME THAT THE FRONT BRAKE LINES ARE VERY RUSTY AS WELL AS THE FUEL LINES AND THE COOLING LINES GOING TO THE TRANSMISSION. THIS SITUATION IS VERY DISTURBING SINCE I HAVE VERY LOW MILEAGE. THE TUBING USED FOR THE BRAKE AS WELL AS THE FUEL LINES SHOULD BE ABLE TO WITHSTAND RUSTING FOR THE LIFE OF THE VEHICLE. IF THE MATERIAL USED BY GM WAS NOT UP TO SPECIFICATION AS FAR AS CORROSION PROTECTION EITHER COMPENSATION TO REPAIR IT IS IN ORDER A RECALL SHOULD BE MADE.

  THE PASSENGER SIDE CLIMATE CONTROL WOULD RECEIVE AN IMPROPER VOLTAGE READING. THE SYSTEM WOULD TURN TO ITS PRESET DEFAULT SETTINGS. (ON FULL HEAT) IT WAS THEN NECESSARY TO STOP THE VEHICLE, TURN OFF THE IGNITION SYSTEM. THIS WILL ALLOW THE CLIMATE CONTROL SYSTEM TO RESET ITS SELF. THIS HAPPENED ONLY ONE TIME PER DAY. (NOT ALWAYS AT THE START OF THE DAY.) TROUBLESHOOTING THIS SYSTEM WAS A TIME CONSUMING PROCESS. (5 TRIPS TO THE SHOP JUST FOR THIS) TO FIX THIS THE PASSENGER SIDE CLIMATE CONTROL SYSTEM WAS REPLACED.

IF YOU SWITCH THE IGNISTION OFF AND ON SEVERAL TIMES IT WILL EVENTUALLY GO BACK TO 0MPH. I WAS DOING SOME RESEARCH ON IT AND FOUND THIS WEB SITE WWW.TOPIX.NET. I FOUND OUT PRETTY QUICK THIS IS NOTHING NEW. THERE WERE SO MANY LISTINGS ON THERE FOR THE SAME PROBLEM THAT IT WAS UNREALISTIC. I HAVE ALWAYS OWNED CHRYSLER PRODUCTS UNITLL I PURCHASED MY GMC. I HAVE DONE NOTHING BUT BRAGG ABOUT HOWW I DON'T NEVER HAVE PROBLEMS WITH THIS TRUCK BUT NOW SEEING ALL OF THESE COMPLAINTS FOR THE SAME THING I KINDA FEEL LIKE AN IDIOT. THIS IS A VERY BIG SAFETY ISSUE EXSPECIALLY WHEN TRAVELING THE INTERSTATES. THIS COULD CAUSE SOME PRETY SERIOUS WRECKS WHEN YOUR SHOWING YOUR RUNNING 100MPH AND ONLY DOING 60MPH. THATS ASKING FOR A MAJOR REAR END COLLISION. IF ANY ONE IS LISTENING AND IS CONSERNED ABOUT THE CONSUMERS SAFETY THEN SOMETHING NEEDS TO BE DONE PRETTY QUICK. I HAVE READ WHERE CONSUMERS HAVE SPENT THOUSANDS OF DOLLARS TO MAKE THIS REPAIR. WITH AS MANY COMPLAINTS I HAVE READ THERE SHOULD BE SOMETHING DONE PRETTY QUICK BEFORE SOMEONE GETS INJURED OR EVEN KILLED. SO IF ANY ONE CARES DO SOMETHING ABOUT IT. *NM

I AM ADDITIONALLY CONCERNED THAT THIS FAILURE WILL OCCUR AFTER MY WARRANTY EXPIRES. I WOULD LIKE TO REQUEST THAT THE INJECTOR ISSUES BE RESEARCHED FOR 2003 DURAMAX ENGINES, AND THAT A RECALL BE ISSUED TO UPDATE VEHICLES WITH NEW INJECTORS THAT DON'T EXHIBIT THE SAME FLAWS/FAILURES, OR REQUEST THAT THE ENGINE WARRANTY BE EXTENDED TO 200,000 MILES AS WAS DONE ON THE 2001-02 MODELS.

  MY TRUCK ONLY HAS HALF OF IT'S BRAKING POWER. THE BRAKE PADS ARE RUSTED TO THE SLIDES & HAVE NOT MOVED FOR A VERY LONG TIME THE ROTORS ON ALL 4 WHEELS ARE COMPLETELY ENGULFED IN RUST. THESE ARE THE ORIGINAL BRAKES. I TOOK THE TRUCK TO GMC FOR SERVICE [OIL CHANGE] & THEY STATED THE REAR ROTORS WERE "VERY RUSTY". I ASKED THE SERVICEMAN WHAT TO DO & HE SAID EITHER I NEEDED TO HAVE THE ROTORS TURNED OR THE BRAKES WOULD WEAR OUT PREMATURELY. IT IS OBVIOUS TO ME NOW [AFTER LOOKING AT THE BRAKES PERSONALLY] THAT THEY WERE NOT WORKING OR THE ROTORS WOULDN'T BE RUSTY AT ALL. THERE WAS NEVER ANYTHING SAID ABOUT THE BRAKES NOT WORKING OR THE EXTREME SAFETY ISSUE OF A 3/4 TON TRUCK GOING DOWN THE ROAD WITH ONLY HALF OF IT'S BRAKING POWER. I TALKED TO THE BBB AND THEY SAID WHEN I TOOK THE TRUCK IN IT HAD 48000 MILES ON IT & WAS OUT OF WARRANTY. I HAVE NO DOUBT THAT THIS SITUATION STARTED BEFORE THE WARRANTY EXPIRED BUT I WAS NOT AWARE OF IT. MY TRUCK IS A 2003 AND I TAKE VERY GOOD CARE OF IT [SERVICED REGULARLY AND GARAGE KEPT] AND THERE IS NO REASON THE BRAKES SHOULD HAVE RUSTED THIS WAY UNLESS INFERIOR PARTS OR WORKMANSHIP IS INVOLVED. I KNOW TWO OTHER PEOPLE WITH SIMILAR TRUCKS AND ONE OF THEM HAS EXACTLY THE SAME PROBLEM AS MINE. WE LOOKED AT HIS AFTER I DISCOVERED MY PROBLEM. HE, AS I, WERE UNAWARE OF THIS DANGEROUS PROBLEM. I THINK THERE ARE A LOT OF GENERAL MOTORS TRUCKS OUT THERE WITH THIS SAME PROBLEM THAT PEOPLE ARE UNAWARE OF. I BELIEVE THERE SHOULD BE A RECALL OR AT LEAST AN INDEPENDENT STUDY ON THIS POTENTIALLY DEADLY SITUATION BEFORE SOMEONE DIES IF THEY HAVEN'T ALREADY.
