2004 GMC SIERRA 2500 Service Brakes, Hydraulic Problems

THE COMPLAINT IS THAT THE BRAKE LINES FAILED AND ARE MADE OF VERY POOR MATERIAL. THE BRAKE LINE FAILED ON MY WAY TO WORK ONE DAY ON MARCH 10,2015.

BOTH FRONT HYDRAULIC BRAKE LINES CORRODED ON DRIVERS SIDE, WITH LOSS OF BRAKING, ON CHASSIS TOP REAR OF FRONT WHEEL. IT APPEARS THAT THERE IS A LARGE WIRING LOOM (1 1/2" O.D.) CLIPPED ON TOP OF HYDRAULIC LINES, ONE TO LF AND RF WHEELS. CORROSION ON BOTH LINES ARE AT THE CONTACT OF THE LOOM AND LINES. VIBRATION MAY HAVE CAUSED THE LOOM AND LINES TO RUB AND ALLOWED MOISTURE TO CORRODE THE BRAKE LINES. *TR

MY TRUCK IS A WORK TRUCK DRIVEN BY AN EMPLOYEE, I HAVE JUST RECENTLY BECOME AWARE OF A CONDITION REGARDING THE INSTRUMENT CLUSTER, WHEREIN THE WHOLE PANEL DOES NOT WORK, I WAS ADVISED BY THE EMPLOYEE THAT THIS HAPPENED QUITE SOME TIME AGO, BUT WAS NEVER MADE AWARE. I CONTACTED GMC BUT APPARENTLY, BECAUSE THIS IS CONSIDERED A SPECIAL POLICY RECALL (ONLY IF SOMEONE COMPLAINS - AND WITHIN A SPECIFIED TIME PERIOD 7 YRS OR 80,000 MILES) THEY WILL NOT REPAIR THIS DEFECT. I NEVER RECEIVED A NOTICE, NOR WAS I AWARE OF THE PROBLEM WITHIN THAT TIME PERIOD. I WAS FURTHER INFORMED BY MY WORKER THAT AT THE TIME THE PANEL WENT OUT, THE FAN FOR THE HEATER/AIR CONDITION UNIT APPEARED TO SMOKE AND NOW IT DOES NOT WORK. HERE AGAIN, I HAVE NOT RECEIVED ANY RECALL NOTICES FOR THIS DEFECT EITHER. FINALLY, IN MY ATTEMPTS TO GET THE CLUSTER REPAIRED, I HAVE BEEN INFORMED THAT THERE IS A RECALL ON THE HYDRO BOOST ACCUMULATOR... I HAVE NOT ONCE RECEIVED A RECALL NOTICE ON THIS VEHICLE AND I PURCHASED THIS VEHICLE NEW. MY VEHICLE HAS 101,000 MILES ON IT. YOU WOULD THINK THAT A VEHICLE OF THIS NATURE WOULD LAST LONGER THAN 100,000. BUT APPARENTLY NOT... ALSO, WHEN THESE IS SUCH A MAJOR RECALL OUT ON A VEHICLE YOU WOULD THINK THAT GMC WOULD CONTACT YOU AND ADVISE YOU OF THIS PROBLEM.. *TR

WHEN COMING TO A STOP THE PEDAL WENT TO FLOOR AND HAD NO BRAKES. LUCKILY I WAS ABLE TO SWERVE AND MISS THE VEHICLE IN FROM OF ME. BUT HAD TO RUN THROUGH THE FOUR WAY STOP AND WAS BLESSED TO HAVE NO OTHER VEHICLES IN WAY. THE BRAKE FLUID WAS LEAKING FROM UNDER THE DRIVER SIDE ABOUT WHERE THE SEAT IS. UPON INVESTIGATION, THE LINES ARE ALL CORRODED AND RUSTING. OBVIOUSLY IT ONLY TAKES ONE TO LEAK BUT ALL NEED TO BE REPLACED. THIS IS SUCH A SURPRISE BECAUSE THIS TRUCK SITS IN THE GARAGE MOST OF THE TIME AND HAS VERY FEW MILES ON IT. *TT

BRAKE LINES ARE ROTTED OUT. I PUSHED ON MY BRAKE PEDAL WHILE COMING TO A RED LIGHT AND IT WENT TO THE FLOOR, THE RUSTED LINES HAD BROKEN AND MY BRAKES DID NOT WORK. LUCKILY I WAS NOT GOING TO FAST OR TO CLOSE TO THE CAR IN FRONT OF ME SO I WAS ABLE TO SLOW ENOUGH TO TURN OFF THE ROAD BY PUSHING IN MY PARKING BRAKE. *TR

WHILE TOWING 4000# BOAT, APPROACHED TRAFFIC SIGNAL AND APPLIED BRAKES WHILE MOVING AT APPROX 10 MPH, THE BRAKES APPLIED AND THE PEDAL THEN BOTTOMED OUT ON THE FLOOR.

THIS COMPLAINT COVERS MY 2004 GMC SIERRA 2500HD CREW CAB 4WD. ALMOST ONE YEAR AGO I HAD A MAIN BRAKE LINE BLOW UNDERNEATH THE DRIVERS SIDE OF THE TRUCK. THE LINE WAS SO CORRODED IT WAS NO WONDER. THIS INCIDENT HAPPENED ON 9-7-10. I WAS HOOKED TO MY FIFTH WHEEL CAMPER AND WAS PREPARING TO PULL OUT OF DRIVEWAY AND WHEN I PLACED FOOT ON BRAKE TO SHIFT INTO DRIVE IT BLEW. THANKFULLY I WAS JUST BEGINNING TO MOVE. I HAD THE TRUCK TOWED TO MY LOCAL MECHANIC AND HE REPLACED THE LINE AND FLUSHED SYSTEM. NOW AGAIN ON 8-22-11 SAME SITUATION OCCURRED. THE LINE BLEW IN EXACTLY THE SAME POSITION AS FIRST TIME ONLY A DIFFERENT LINE THIS TIME. NOT TO MENTION THE OTHER CORROSION ON THE BRAKE CALIPERS AND HARDWARE THAT RENDERED MY REAR BRAKES USELESS. HAD TO REPLACE ROTORS AND PADS DUE TO STICKING BRAKE PAD WEARING TO POINT OF METAL TO METAL CONTACT. DID I MENTION I PURCHASED THIS TRUCK NEW AND IT NOW HAS ONLY 38,500 MILES. RARELY DOES IT GET DRIVEN IN SNOW AND SALT. I HAVE ALL RECEIPTS FOR PARTS THAT THIS PROBLEM HAS CAUSED ME. IM JUST THANKFUL THAT I WASN'T TOWING AS I USUALLY DO WHEN IM DRIVING THIS TRUCK. I'VE TALKED TO MY LOCAL DEALERSHIP DON HALL IN ASHLAND, KY AND THEY CITE HUNDREDS OF TRUCKS HAVING THIS SAME PROBLEM. WHEN ARE THEY GOING TO DO SOMETHING ABOUT THIS. I AM A LOYAL GM FAN BUT I WORKED AT A TOYOTA DEALERSHIP FOR TWO YEARS SELLING USED VEHICLES. I MADE IT A HABIT OF CHECKING ALL OF OUR GM TRUCK TRADE-INS FOR THIS RUST PROBLEM AND THEY TOO HAD THIS. I SAW EVEN TWO TO THREE YEAR OLD VEHICLES RUSTED TO THE POINT OF COLLAPSE. ONE OF THESE BEING A $65000 CADILLAC ESCALADE. APPALLING. *TR

I OWN A 2004 GMC SIERRA 2500HD 4WD TRUCK. IT HAS 90,500 MILES ON IT. MULTIPLE BRAKE LINES UNDER THE DRIVER SIDE DOOR HAVE RUSTED AND ARE LEAKING BRAKE FLUID. THE VEHICLE IS UNSAFE TO DRIVE AT THIS POINT UNLESS REPAIRS ARE MADE COSTING ME OVER $1000. I CANNOT DRIVE THE TRUCK UNTIL REPAIRS ARE MADE. IT APPEARS AFTER DOING SOME ONLINE RESEARCH THAT THERE IS ALREADY A NHTSA INVESTIGATION CONCERNING PREMATURE BRAKE LINE RUSTING/FAILURE ON GM TRUCKS. I HAVE DRIVEN CARS THAT ARE OVER 30 YEARS OLD AND THEY DO NOT HAVE THE KIND OF RUST I HAVE ON MY GMC SIERRA THAT IS ONLY 7 YEARS OLD!!! PLEASE MAKE GM DO A RECALL ON THIS DESIGN FAILURE. THEY ARE ENDANGERING THE LIVES OF THEIR CUSTOMERS! *TR

LOST BRAKES WHILE DRIVING 35 MPH WAS ABLE TO STOP AND NOTICED BRAKE FLUID DRIPPING FROM ABOVE GAS TANK JUST FORWARD OF REAR AXLE ON DRIVERS SIDE.

NEW LINE IS SEVERELY CORRODED AT EACH GREEN PLASTIC CLIP AFTER ONLY 7 MONTHS.

I WAS APPROACHING AN INTERSECTION IN MY 2004 GMC SIERRA 4X4 2500HD PICKUP TRUCK WITH A 2800 POUND TRAILER WHEN I PRESSED THE BRAKES TO STOP. THE BRAKE PEDAL WENT TO THE FLOOR AND I WAS UNABLE TO STOP. THE TRAILER BRAKES WERE NOT ENOUGH TO STOP THE VEHICLE AND I CONTINUED INTO THE INTERSECTION AND WAS ALMOST STRUCK BY TWO OTHER VEHICLES. THEY JUST MISSED HITTING MY VEHICLE AND CAUSING SERIOUS INJURIES TO MYSELF AND MY PASSENGER, AS WELL AS THEMSELVES. WHEN I OPENED THE HOOD THERE WAS BRAKE FLUID ALL OVER THE DRIVERS SIDE OF THE ENGINE COMPARTMENT. I HAD THE VEHICLE TOWED TO THE NEAREST GMC DEALER. THE DEALER TOLD ME THAT A BRAKE LINE HAD BURST AND NEEDED TO BE REPLACED. HE ALSO STATED THAT ALL THE BRAKE LINES WERE CORRODED AND NEEDED TO BE REPLACED AT $750.00 PER SIDE. HE TOLD ME THAT THIS WAS A COMMON PROBLEM FOR THESE VEHICLES AND THAT THESE LINES ONLY LAST 4-7 YEARS ON AVERAGE. THERE IS ALSO SIGNIFICANT CORROSION ON THE FRAME. MY VEHICLE IS ALWAYS GARAGED AND REGULAR MAINTENANCE IS DONE. THE DEALER THEN TOLD ME THAT SINCE WE LIVE IN A SNOW BELT STATE THAT I SHOULD EXPECT THIS AND THAT GMC WILL NOT HELP WITH THE REPAIR. I TOLD HIM THAT I AM VERY UPSET AND THAT I HAVE BEEN A FIREFIGHTER/PARAMEDIC FOR OVER 25 YEARS, AND IF WHAT HE JUST SAID WAS TRUE, THEN I WOULD HAVE HAD TO RESCUE AN AWFUL LOT OF PEOPLE FROM THEIR CRASHED VEHICLES IF ON AVERAGE BRAKE LINES ONLY LASTED 4-7 YEARS. I FEEL THAT THIS NEEDS TO BE REPORTED AND INVESTIGATED BECAUSE IT IS A VERY SERIOUS SAFETY ISSUE AND PEOPLE ARE GOING TO GET HURT IF WHAT THE DEALER TOLD ME IS TRUE. I WOULD APPRECIATE IT IF YOU WOULD LOOK INTO THIS MATTER. AT THIS POINT MY VEHICLE IS SITTING AT THE DEALERSHIP IN AN UNREPAIRED CONDITION UNTIL FURTHER ACTION BY EITHER GMC OR NHTSA HAPPENS. *TR

1. APPLIED BRAKES WHEN LEAVING DRIVEWAY. 2. BRAKES FAILED COMPLETELY. 3. BRAKE LINES COMPLETELY RUSTED OUT. RIGHT FRONT FAILED ALLOWING BRAKE FLUID AND REQUISITE PRESSURE TO ESCAPE. I REPLACED THE FAILED SECTION. *TR

TL*THE CONTACT OWNS A 2004 GMC SIERRA 2500 HD. THE CONTACT STATED THAT BOTH REAR BRAKE PADS AND ROTORS WERE WORN, IN ADDITION TO THE FRONT PASSENGER SIDE BRAKE PAD AND ROTOR. THE CONTACT FEELS THAT THE BRAKE PADS AND ROTORS SHOULD NOT HAVE FAILED AT 36,000 MILES. THE MANUFACTURER TOOK A REPORT AND STATED THAT THE FAILURE WAS NOT A DEFECT, BUT RATHER A PART OF NORMAL MAINTENANCE. THEY REFUSED TO ASSIST WITH THE REPAIR. THE VEHICLE HAS NOT BEEN REPAIRED. THE CURRENT AND FAILURE MILEAGES WERE 36,000. UPDATED 11/14/08 *CN THE CONSUMER STATED THE BRAKE PADS WOULD NOT MOVE ON SLIDES. UPDATED 11/19/08. *JB

WHEN SLOWING USING THE BRAKE SYSTEM, THE VEHICLE ACTUALLY LOSES BRAKING EFFECTIVENESS FOR A SHORT TIME (LESS THAN 1 SECOND) JUST BEFORE THE VEHICLE ACTUALLY STOPS- AT ABOUT 3 TO 5 MPH. THE IS THEN A PULSING FEEL IN THE BRAKE PEDAL AND THE VEHICLE THEN STOPS. THE POINT IS THAT THERE IS ACTUALLY A MOMENTARY LOSS OF BRAKING EFFECTIVENESS IN THE LAST FEW MOMENTS OF A NORMAL STOP. FORTUNATELY, THEM, ONLY "LOW SPEEDS" ARE INVOLVED; UNFORTUNATELY, THIS IS VERY UNSETTLING WHEN STOPPING AT A BUSY INTERSECTION OR IN CONGESTED TRAFFIC. IT LEAVES ONE WONDERING IF/WHEN THE BRAKE FUNCTION WILL ACTUALLY FAIL ALTOGETHER. I HAD THE PROBLEM INVESTIGATED BY MY DEALER AND WAS TOLD THAT IT INVOLVED THE ANTI LOCK SENSORS WHICH MAY BE FIXED BY CLEANING. IF THAT WOULDN'T FIX THE PROBLEM, THE SENSORS WOULD HAVE TO BE REPLACED. COSTS: CLEANING $160; REPLACEMENT: $1250. CLEANING DID NOT CORRECT THE PROBLEM. *TR

THE PROBLEM PERSISTED, AND HE RETURNED TO THE DEALER. THE DEALER PERFORMED A DIAGNOSTIC TEST THAT PRODUCED NORMAL CODES. THERE WAS TECHNICAL SERVICE BULLETIN PIT3310 , AND THE CONTACT FELT THIS WAS RELATED TO THE ONGOING PROBLEM. NO FURTHER REPAIRS HAVE BEEN MADE. *AK
