2004 GMC Sierra

TL* THE CONTACT OWNS A 2004 GMC SIERRA. THE CONTACT STATED THAT THE BRAKE PEDAL BECAME STUCK TO THE FLOOR BOARD. THE VEHICLE WAS TOWED TO THE DEALER, WHO INSPECTED THE VEHICLE AND FOUND THAT THE REAR BRAKE LINE WAS LEAKING DUE TO CORROSION. THE REAR BRAKE LINE WAS REPLACED. THE MANUFACTURER WAS NOT AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 97,047 AND THE APPROXIMATE FAILURE MILEAGE WAS 99,000. UPDATED 11-04-13 *BF UPDATED 11/8/2013 *JS

VEHICLE IN FRONT OF ME STOPPED SUDDENLY. MY BRAKES FAILED AS MY FOOT/PEDAL HIT THE FLOOR. ALL I HEARD WAS BUZZING. I HIT THE VEHICLE IN FRONT OF ME. MECHANIC SHOWED ME THE RUSTED OUT BRAKE LINE THAT FAILED. ADVISED ME THAT THE ABS PUMP JUST PLAN EMPTIED MY MC TO MAKE UP PRESSURE LOSS. MY COMPLAINT ISN'T SO MUCH THE FACT THAT MY BRAKE LINE RUSTED OUT AS IT IS A 10 YEAR OLD TRUCK, (ALTHOUGH STAINLESS LINES WITH STEEL CONNECTORS WOULD BE A HUGE IMPROVEMENT). BUT MY COMPLAINT IS THAT THE ABS SYSTEMS IN THESE TRUCKS, AND MAYBE OTHER VEHICLES ARE FLAWED. BACK BEFORE ABS CAME OUT, IF A LINE WAS DAMAGED OR FAILED FOR WHATEVER REASON THE SEPARATED RESERVOIRS IN MC'S WOULD AT LEAST GIVE YOU FRONT OR REAR BRAKES TO STOP. THAT WAS THE BEST SINGLE DESIGN IMPROVEMENT MANUFACTURERS MADE TO BRAKES, AND I'VE BEEN DRIVING WHEN MC'S ONLY HAD ONE RESERVOIR. TO HAVE A COMPLETE MC DRAINED FOR A LINE FAILURE IS LUDICROUS. *TR

DRIVING ON THE FREEWAY, I STEPPED ON THE BRAKES TO SLOW DOWN AS TRAFFIC WAS HEAVY IN A AREA THAT IS SLOW IN THE MORNING. THE BRAKES STARTED TO SLOW ME DOWN, THEN WITHOUT WARNING THE PEDAL WENT TO THE FLOOR AND I COULD NOT SLOW THE TRUCK. I TOOK ACTION AND MOVED ONTO THE NEXT LANE TO AVOID A CRASH. I CONTINUED TO APPLY THE BRAKES WHICH ONLY WORKED A LITTLE BIT UNTIL I CAME TO A STOP. I HAD THE TRUCK TOWED TO MY HOUSE. UPON INSPECTION, ONE OF THE FOUR BRAKE LINES THAT RUN ALONG THE OUTSIDE OF THE FRAME UNDER THE DRIVERS SEAT HAD BURST DUE TO EXTENSIVE RUST. IN FACT ALL FOUR OF THE BRAKE LINES IN THIS LOCATION HAD EXTENSIVE RUST. I HAD TO HAVE ALL FOR REPLACED. *TR

UPON APPLYING BRAKES TO SHIFT INTO REVERSE, PEDAL WENT TO FLOOR AND ALL WARNING LIGHTS CAME ON. HAD TRUCK TOWED TO GARAGE, AND UPON INSPECTION A METAL BRAKE LINE HAD RUSTED OUT. AFTER REPLACING BRAKE LINE GARAGE WAS BLEEDING BRAKES AND ANOTHER LINE FAILED. WAS TOLD BY MECHANIC THAT I SHOULD HAVE ALL THE METAL LINES REPLACED BECAUSE OF SEVER RUSTING OF THE METAL. THIS SEEMS TO BE MORE PREVALENT IN GENERAL MOTORS THAN ANY OTHER BRAND. I WAS TOLD THAT THE USE OF SALT BRINE SOLUTION IN OUR AREA FOR WINTER FREEZING IS THE REASON BEHIND THIS. I WAS TOLD THAT THE MECHANIC IS SEEING AT LEAST ONE VEHICLE A WEEK WITH THIS PROBLEM. *JS

MY MOTHER BORROWED MY TRUCK TO RUN AN ERRAND ON HER WAY HOME SHE CALLED TO TELL ME THAT THE "SERVICE BRAKE SYSTEM" MESSAGE HAD APPEARED IN THE DIC. MOMENTS LATER THE VEHICLE LOST ALL STOPPING ABILITY. THANKFULLY DUE TO THE COMBONATION OF AN EMPTY ROAD GOOD DRIVING NO COLLISION OCURED. THIS MORNING I GO TO INVEGISTATE TO FIND COMPLETE RUST THROUGH ON TWO OF THE STEEL HYDRAULIC LINES LOCATED JUST BEHIND THE DRIVERS FRONT WHEEL. ALL STEEL LINES IN THIS TRUCK BRAKE, FUEL, AND, TRANSMISSION COOLER HAVE SIMILAR EXTENSIVE RUST DAMAGE. THIS IS EXTREMELY DANGERIOUS AND WILL BE EXPENSIVE TO REPAIR AS TO ENSURE SAFETY ALL METAL LINES WILL NEED CHANGING. I CAME TO FIND OUT THAT NOT ONLY IS THIS A VERY COMMON ISSUE WITH THESE TRUCKS BUT THAT GM IS DOING NOTHING TO HELP OWNERS NOR DO THEY OFFER CORRECT QUALITY OE STYLE REPLACEMENT LINES. I WAS QOUTED OVER $1000 BY TWO SEPERATE DEALERS IN MY AREA. MY TRUCK IS WELL TAKEN CARE OF AND IS DRIVEN MUCH LESS THAN THE NATIONAL AVERAGE THIS FAILURE HAS TRULY UPSET ME I DONT SEE BUYING ANOTHER GM PRODUCT IN THE FUTURE. *TT

I HAVE A 2004 GMC SIERRA THAT HAS AN ELECTRICAL ISSUE WITH THE ABS OR BRAKE SYSTEM. THE BRAKE LIGHT, ABS LIGHT AND SERVICE BRAKE SYSTEM LIGHT GOES OFF AT RANDOM TIMES. MIGHT HAVE SOMETHING TO DO WITH THE AIR CONDITIONING BECAUSE THE A/C DRAWS POWER FROM THE BATTERY AND I CAN SEE THAT A CERTAIN LEVEL THE INDICATORS GO OFF. MOST OF THE TIME THE LIGHTS CHIME AND BLINK WHEN I APPLY THE BRAKE BUT IT ALSO HAS HAPPENED WHEN JUST TURNED THE TRUCK ON. I'VE REPLACED THE ROTORS AND PADS TO STILL HAVE THE PROBLEM. I'M NOT SURE IF IT'S A GROUND OR SENSOR THAT IS FAILING. I'VE FOUND TSB FOR REGROUNDING, FAILING SENSORS, OR ECBM. STILL HAVEN'T FOUND THE CORRECT DIAGNOSIS. I JUST HOPE THE ABS FUNCTIONS WHEN I NEED IT. *TR

WHEN COMING TO A RED LIGHT I TRIED TO STOP MY TRUCK. UPON PRESSING THE BRAKE PEDDLE THE FIRST TIME I STARTED TO SLOW DOWN. UPON PRESSING THE BRAKE PEDDLE THE SECOND TIME, THE PEDDLE WHEN TO THE FLOOR AND DID NOT SLOW ME DOWN. I HAD TO RUN THE RED LIGHT AND US MY E BRAKE TO SLOW DOWN AND FINALLY STOP AT A GAS STATION. WHILE WAITING FOR AAA TO PICK ME UP NOTICED BRAKE FLUID COMING OUT FROM UNDER DRIVERS SIDE. TRUCK WAS TOWED TO MY SON'S HOUSE. AFTER LOOKING UNDER THE TRUCK HE TOLD ME THE BRAKE LINES FROM THE FRONT OF THE TRUCK HAD BROKEN. HE SUGGESTED WE REPLACE ALL THE BRAKE LINES, WHICH WE DID. ALL THE ORIGINAL LINES WERE ROTTING AWAY. WHEN WE REMOVED THE BRAKE LINES THEY ALL BROKE INTO PIECES . WE REPLACED ALL THE ORIGINAL LINES WITH STAINLESS STEEL LINES AT COST OF $400.00 PLUS I FOUND A FRONT AND A REAR CALIPERS FROZEN, SO I REPLACED ALL THE BRAKES AND CALIPERS. THERE IS NO WAY THE BRAKE LINES ON A 8 YEAR OLD TRUCK SHOULD BE FOUND IN THIS SHAPE. THE ORIGINAL LINES LOOKED LIKE ALUMINUM COATED STEEL. *TR

I LEFT MY HOUSE FOR WORK AND APPROX. 3 BLOCKS FROM MY HOUSE I ATTEMPTED TO SLOW DOWN TO MAKE A RIGHT HAND TURN. I PRESSED ON THE BRAKES AND THE PEDAL WENT ALL THE WAY TO THE FLOOR. I HAD NO BRAKES. AT THIS TIME AND THIS WAS THE FIRST TIME, THE BRAKE LIGHT ON THE DASH CAME ON. I WAS DRIVING AT 30 MPH WITH NO BRAKES, I COASTED INTO A PARKING LOT AND USED THE PARKING BRAKE TO STOP THE TRUCK. OUTSIDE AND UNDER THE DRIVERS DOOR OF THE 2004 SIERRA EXTENDED CAB THERE WAS BRAKE FLUID LEAKING. THE 8 YEAR OLD TRUCK HAD RUSTED BRAKE LINES THAT FAILED. MY CONCERN IS THAT I LOST ALL BRAKES WITHOUT WARNING. AFTER A LITTLE RESEARCH I NOTICED MANY OF THESE TRUCKS HAVE THE SAME PROBLEM. THEY ARE 5000 POUND TORPEDOS ON THE ROAD AND WITHOUT WARNING. WILL SOMETHING BE DONE BEFORE A SERIOUS ACCIDENT OCCURS? I TRIED CONTACTING GMC VIA THEIR WEBSITE E-MAIL BUT AN ERROR MESSAGE OCCURRED. TRY A COMPLAINT ON THEIR SITE.....IT DON'T WORK!!! *TR
