2004 GMC SIERRA Service Brakes Problems

I HAVE A 2004 GMC SIERRA AND ALL OF A SUDDEN MY AIRBAG LIGHT AND ABS LIGHT CAME ON TOOK IT IN TO HAVE IT LOOKED AND THE AIRBAGS ARE NOT COMMUNICATING WITH THE SENSOR AND THEY WOULD HAVE TO GO MORE IN DEPTH ON THE ABS BUT TO GO MORE IN DEPTH THEY CHARGE $80.00 AN HOUR JUST TO BE ABLE TO FIGURE IT OUT. I HAVE SEEN SIMILAR RESPONSES ON THE AIRBAG LIGHT FOR THIS VEHICLE PLEASE HELP.

RUSTED OUT/ CORRODED BRAKE LINES BURST WHILE STOPPING FOR A DEER RUNNING OUT ON THE ROAD. WAS WARNED OF THIS PROBLEM UPON PURCHASE OF THE VEHICLE IN 2010 AND PERSONALLY COATED ALL BRAKE LINES B4 WINTER EVERY YEAR...NEVER SAW WORSE LINES! I OWN CLASSIC CARS THAT ARE TWICE AS OLD WITH SHINEY ORIGINAL BRAKE LINES. THE FUEL LINES ALSO ROTTED OUT SPILLING FUEL OVER THE TOP OF THE FUEL TANK AND ON THE GROUND WHILE FILLING UP. ALL FUEL LINES AND FUEL PUMP CONNECTIONS WERE SEVERELY ROTTED. WORST I HAVE SEEN. DASH CONSISTENTLY CHANGES LANGUAGES RENDERING ODOMETER NON FUNCTIONAL. SPEEDOMETER IS INACCURATE SOME TIMES NOT EVEN WORKING ESPECIALLY ON COLD DAYS. HMMMM ROTTED BRAKES+NO SPEEDOMETER+LEAKY FUEL LINES=CRASH,BANG BOOM!..AND I HAVE A CAR SEAT IN MY VEHICLE! LUCKLY I PERFORM PREVENTATIVE MAINTENANCE AND DRIVE SAFELY. STILL WONDER HOW THESE ISSUES GOT SWEPT UNDER THE RUG.

RUSTED BRAKE LINE

Mileage: 111,500

I EXPERIENCED A BRAKE LINE FAILURE ON MY 2004 GMC SIERRA CREW CAB PICKUP TRUCK. I WAS TRAVELING AT A SLOW RATE OF SPEED AND COMING UP TO A TRAFFIC LIGHT AND THE BRAKE PEDAL PUSHED ALL THE WAY TO THE FLOOR BOARD. THE REAR EMERGENCY BRAKE WAS USED TO STOP THE VEHICLE. I FOUND THE AREA AROUND THE BRAKE MODULE, IN THE FRAME AREA UNDER THE DRIVER'S AREA, SOAKED WITH BRAKE FLUID AND CORRODED BRAKE LINES.

ON DECEMBER 28, 2014 I WAS DRIVING MY 2004 GMC PICK-UP TRUCK AND SUFFERED TOTAL LOSS OF BRAKES. THIS HAPPENED AS I WAS APPROACHING AN INTERSECTION AND I NARROWLY AVOIDED AN ACCIDENT. THERE WAS NO WARNING PRIOR TO THE BRAKE FAILURE - NO WARNING LIGHT WAS ON, AND NO GRADUAL DECREASE IN BRAKING ABILITY. AFTER THE FAILURE, I DETERMINED THAT THERE WAS A SUDDEN AND MASSIVE LEAK OF BRAKE FLUID FROM A RUSTED BRAKE LINE. PREVIOUSLY, IN APRIL OF 2014 I HAD MY PICK-UP TRUCK SERVICED AT AN AUTHORIZED GMC SERVICE CENTER. AT THAT TIME, THE SERVICE TICKET REFERENCED CONDITION OF BRAKES TO BE IN YELLOW REQUIRING FUTURE ATTENTION. IT WAS MY UNDERSTANDING THAT THE ISSUE AT THAT TIME WAS BRAKE ROTORS WOULD NEED TO BE REPLACED AT THE NEXT SERVICE INTERVAL. THERE WAS NO MENTION OF ANY POTENTIAL DANGER FROM BRAKE LINE RUSTING/FAILURE. UPON RESEARCHING VEHICLE ISSUES ON THE WEB I HAVE DISCOVERED THAT THERE SEEMS TO BE AN INORDINATE NUMBER OF BRAKE LINE FAILURES FOR VEHICLES OF MY TYPE. IT APPEARS GMC HAS REFUSED TO ISSUE A RECALL. I HAD MY VEHICLE TOWED TO THE GMC DEALER AND HAD THEM REPLACE RUSTING BRAKE LINES ($801.64). THE REPLACEMENT GMC BRAKE LINES INSTALLED ARE OF A DIFFERENT (IMPROVED) DESIGN - THEY HAVE A PAINTED/PROTECTIVE COATING ON THEM, WHICH APPEARS TO BE AN ATTEMPT TO ADDRESS PAST PREMATURE BRAKE LINE FAILURE ISSUES.

AGAIN. MY TRUCK HAD COMPLETE BRAKE FAILURE AGAIN DUE TO CORROSION ON THE STEEL LINES. THIS IS AN OTHERWISE NICE TRUCK WITH BRAKE LINES THAT LOOK LIKE THEY'VE BEEN IN THE OCEAN THEIR ENTIRE LIVES. GM DEALER QUOTED OVER $1,700 TO FIX. GM OWNED WARRANTY COMPANY REFUSES TO COVER REPAIR. GM CUSTOMER SERVICE TELLS ME TO POUND SAND. *TR

DRIVING ON WEST STONE DRIVE KINGSPORT, TN, A VEHICLE CUT ME OFF TRYING TO GET THRU A TRAFFIC LIGHT, I LOCKED MY BRAKES DOWN HARD AS I COULD, I COULD FEEL THE ABS SYSTEM WORKING, I WAS ABLE TO STOP ABOUT 12 INCHES FROM THE OTHER VEHICLE. WHEN I PULLED OUT AFTER THE LIGHT CHANGED TO GREEN, I WAS TRAVELING DOWN A SLIGHT GRADE, DEPRESSING MY BRAKE PEDAL LIGHTLY, THE PEDAL WENT ALL WAY TO THE FLOOR BOARD.. I TOOK THE TRUCK TO A LOCAL SHOP TO HAVE IT CHECKED, ONE OF THE BRAKE LINES BEHIND LEFT FRONT WHEEL HAD RUPTURED. WHEN THE MECHANIC STARTED THE REPAIRS, HE CALLED SAID ALL LINES ON THIS TRUCK WERE EXTREMELY RUSTY, (HE ASKED WHAT I WANTED TO DO) I SAID FIX IT RIGHT. IN MAKING THE REPAIRS ALL LINES WERE REPLACED.. I HAVE PICTURES OF ALL LINES THAT CAN BE SENT. I ALSO HAVE ALL OF THE BRAKE LINES THAT CAN BE LOOKED AT AND OR ANALYZED. *TR

AFTER HAVING A GM DEALER PERFORM OIL CHANGE, PERHAPS 1/4 MILE DOWN THE STREET FROM THEIR FACILITY ENCOUNTERED TRAFFIC STOPPED AT AN INTERSECTION IN FRONT OF ME. APPLIED THE BRAKES TO FIND THAT THEY FELT MUSHY, AND BEFORE COMPLETELY STOPPING WENT TO THE FLOOR. I USED THE PARKING BRAKE TO BRING THE VEHICLE TO A STOP WITHOUT CRASHING INTO THE CARS IN FRONT OF ME. WHEN THE LIGHT TURNED GREEN I NURSED THE VEHICLE INTO A PARKING LOT USING THE PARKING BRAKE AND LOOKED UNDER THE HOOD AND COULD FIND NO ISSUE, THE WEATHER WAS VERY WET AND SLOPPY, AND LIGHT SNOW SO I COULD NOT SEE THE TELL TALE FLUID LEAKAGE FROM A BRAKE LINE. BECAUSE I HAD LOST ALL BRAKING I ASSUMED THAT THE MASTER CYLINDER HAD FAILED. I HAD CHANGED ALL CALIPERS, ROTORS AND PADS SEVERAL MONTHS BEFORE, AND AT 140,000 THOUGHT THAT THE MASTER CYLINDER FAILING WOULD BE UNUSUAL, BUT THE ONLY THING THAT WOULD CAUSE COMPLETE FAILURE. AFTER REPLACING THE MASTER I ATTEMPTED TO BLEED THE SYSTEM ONLY TO FIND THAT THE PROBLEM REMAINED. NOW THAT THE UNDER HOOD AREA WAS COMPLETELY DRY IT WAS CLEAR THAT THE FAILURE WAS RUST THROUGH AT A POINT THE LINE TO THE LEFT FRONT WHEEL WAS IN CONTACT WITH THE FRAME RAIL BELOW THE MASTER CYLINDER. THE OIL CHANGE HAD PROBABLY CAUSED MOVEMENT OF THE LINE RESULTING IN THE FAILURE. MOVING SOME OF THE OTHER LINES MADE IT APPARENT THAT ALL OF THE HARD LINES WERE SHOT. THE SLIGHTEST MOVEMENT CAUSED THEM TO FRACTURE. WORSE THAN THAT, THEY WERE ALL ENCASED IN A "SHELL" OF RUST FROM ONE END TO THE OTHER, CONCEALING HOW FRAGILE AND DANGEROUS THEY REALLY WERE. REPAIR ESTIMATES WERE ANYWHERE FROM $800 (LOCAL MECHANICS) TO $3,400 (GM DEALER). LOVELY. I HAD A 1994 S10 BLAZER THAT I SOLD A COUPLE OF YEARS AGO WITH 290,000 MILES ON IT, ORIGINAL BRAKE LINES AND ALL. CHANGED THE LINES MYSELF IN A WEEKEND FOR $120.00, THE GM PARTS GUY NEW EXACTLY WHAT I NEEDED AND HAD THE "KIT" IN STOCK, WHAT A SURPRISE. *TR

STARTED OUT WHEN BRAKE FLUID STARTED LEAKING FROM THE TRUCK. BRAKE PEDAL WENT TO THE FLOOR. LUCKILY DID NOT HAPPEN WHEN WAS DRIVING. FOUND OUT THE BRAKE LINES WERE RUSTED AND WAS LEAKING AND THE REPAIR COST WOULD BE OVER $1200. LOOKING ON THE INTERNET THIS LOOKS TO BE A KNOWN FOR CERTAIN GMC/CHEVY YEAR TRUCKS. *TR

I WAS DRIVING IN A 40 MPH STREET WHEN I NOTICED THE TRAFFIC SIGNAL WAS ABOUT TO TURN RED WHEN I APPLIED THE BRAKES THE PEDAL WHEN DOWN TO THE FLOOR I LOST ALL BRAKES I SLOWED DOWN BY DOWN SHIFTING THE TRANSMISSION AND APPLYING THE EMERGENCY BRAKE. WHEN I PULLED OVER THERE WAS BRAKE FLUID LEAKING ALL OVER UNDER DRIVERS SIDE DOOR. UPON INSPECTION I NOTICED THE BRAKE LINES RUSTED OUT AND LOST ALL FLUID. I COULD HAVE BEEN KILLED THERE WAS NO WARNING. I NEEDED TO HAVE MY BRAKE LINES REPLACED I BELIEVE THIS IS A START OF SOMETHING BAD IF GM DOESN'T ACT ON THIS PROBLEM. *TR

I WAS TAKING MY 4 YR OLD TO SCHOOL THIS MORNING WITH HIS 1 YR OLD SISTER WHEN THE BRAKES COMPLETELY FAILED. UPON APPROACHING A RED STOPLIGHT AT 30 MILES PER HOUR WITH THREE CARS STOPPED AHEAD OF ME I PRESSED THE BRAKE PEDAL AND IT WENT COMPLETELY TO THE FLOOR. I PULLED GEARSHIFT TO THE LOW POSITION AND SWERVED INTO THE VACANT LEFT HAND TURNING LANE TO AVOID THE CARS STOPPED AT THE LIGHT. THEN TURNED HARD RIGHT AS TO NOT ENTER THE BUSY INTERSECTION IN FRONT OF ME WITH NO AVAIL. SOMEHOW WE WERE NOT HIT BY ANOTHER VEHICLE. AT THAT TIME I PULLED VEHICLE OVER TO THE SHOULDER OF THE ROAD WHICH ENDED ABRUPTLY AND TURNED INTO A GRASSY AREA OF A BASEBALL FIELD WHERE THE VEHICLE FINALLY CAME TO A STOP.GM STATES THAT IF THERE IS A BRAKE LINE FAILURE THE VEHICLE STILL HAS BRAKING ABILITY. I CAN TELL YOU FIRST HAND THAT IS A TOTALLY FALSE STATEMENT. MY VEHICLE DASH DID NOT DISPLAY ANY PROBLEM PRIOR TO THIS INCIDENT. WHEN VEHICLE WAS TOW TO MY HOME I PUT KEY IN THE IGNITION TO CHECK MY MILEAGE AND NOW A BRAKE FAILURE MESSAGE IS DISPLAYED.I AM VERY ANGRY WITH GM FOR NOT NOTIFYING ME OF THIS PROBLEM AND NEVER HAD ANY IDEA THERE WAS AN ON GOING ISSUE UNTIL TODAY. MYSELF AND MY TWO CHILDREN COULD HAVE BEEN KILLED TODAY BECAUSE OF THIS NEGLECT. PLEASE DO SOMETHING TO RECTIFY THIS PROBLEM BECAUSE MANY MORE GM VEHICLE WILL HAVE THIS PROBLEM AND INNOCENT PEOPLE AND THEIR FAMILIES WILL BE HURT OR EVEN DIE. *TR

BRAKE PEDAL HAD NO PRESSURE AND WENT TO THE FLOOR. TRUCK WOULDN'T STOP. LATER I NOTICED A BRAKE FLUID LEAK. THERE WAS NO LEAK BEFORE THE INCIDENT AND BRAKES WORKED PERFECTLY EARLIER IN THE DAY. IF I HADN'T BEEN IN A PARKING LOT AND OUT ON THE ROAD, THERE WOULD CERTAINLY HAVE BEEN AN ACCIDENT. *TR

THE BRAKE LINE RUPTURED ON MY 2004 GMC SIERRA 1500 PICK UP TRUCK - INSPECTED BY A CERTIFIED MECHANIC, ALL REMAINING LINES NEED TO BE CHANGE DUE TO CORROSION. *TR

ALL FUEL AND BRAKES LIKE ROTTED. THE BRAKES FAILED FOR THE SECOND TIME. ONE BRAKE LINE WAS PREVIOUSLY REPLACED APPROX. 1 YEAR AGO. BOTH TIMES VEHICLE NEEDED TO BE TOWED FOR REPAIR. TOTAL COST FOR MOST RECENT REPLACEMENT/REPAIR WAS $1202.13. *TR

I HAD NOT DRIVEN MY TRUCK IN A FEW MONTHS DUE TO OTHER PROBLEMS WITH THE VENTILATION CONTROLS. WHILE BEGINNING TO PREPARE THE TRUCK TO TOW A 3500 POUND BOAT I NEEDED TO REPOSITION THE TRUCK IN MY DRIVEWAY. THE DRIVEWAY SLOPES DOWN TO THE STREET. WHILE MOVING THE TRUCK, ON MY DRIVEWAY, THE BRAKE PEDAL WENT COMPLETELY TO THE FLOOR. PUMPING THE BRAKES WAS NOT ABLE TO STOP THE TRUCK THAT WAS TRAVELING AT IDLE SPEED. ALL BRAKING WAS GONE AND THE TRUCK ROLLED DOWN THE DRIVEWAY AND INTO TRAFFIC ON MY STREET. BY TURNING OFF THE ENGINE AND COASTING TO A STOP (IN GEAR) JUST AVOIDED AN ACCIDENT. AFTER GETTING THE TRUCK BACK IN MY DRIVEWAY I FOUND TWO DISTINCT PUDDLES OF BRAKE FLUID UNDER THE TRUCK. INSPECTING THE BRAKE LINES SHOWED THAT THERE WERE AT LEAST TWO DIFFERENT FAILURE POINTS IN THE BRAKE LINES. ONE CLOSER TO THE MASTER CYLINDER AND ANOTHER A FEW FEET FURTHER BACK. I BELIEVE ONE FAILURE OCCURRED IN THE FRONT BRAKE CIRCUIT AND THE OTHER WAS IN THE REAR BRAKE CIRCUIT WHICH LED TO THE *COMPLETE* LOSS OF BRAKING. THIS IS CONTRARY TO GM CLAIMS THAT THIS FAILURE CAN NOT LEAD TO TOTAL BRAKE LOSS. I HAVE PICTURES AND VIDEO OF THE FAILURE POINTS THAT I CAN FORWARD IF NEEDED. *TR

I HAD JUST HAD THE TRUCK INSPECTED. WAS DRIVING HOME AND TWO BLOCKS FROM THE INSPECTION STATION WHEN I CAME TO A RED LIGHT. WHEN I STEPPED ON THE BRAKES THE PEDAL WENT TO THE FLOOR. FORTUNATELY I REACTED QUICKLY ENOUGH TO USE THE PARKING BRAKE TO STOP THE TRUCK AND KEEP FROM REAR ENDING THE CAR THAT WAS ALREADY STOPPED. AFTER PULLING INTO PARKING LOT AND INSPECTING THE BRAKES I NOTICED A PUDDLE UNDER THE FRONT LEFT OF THE TRUCK. LOOKING CLOSER I FOUND THE BRAKE LINE HAD RUSTED THROUGH. I RETURNED TO THE SHOP WHERE I HAD THE INSPECTION DONE. HE REPAIRED THE ONE LINE THAT HAD BURST. I WAS INFORMED THAT THE OTHER LINES LOOKED RUSTED AND READY TO BURST AT ANYTIME. *TR

Mileage: 104,000

TRAVELING SOUTH, NY RT. 12. ATTEMPTED TO SLOW FOR A RIGHT TURN. SIGNAL ON, TOWING AN EMPTY TRAILER APPROX WEIGHT 2000 LBS. APPLIED THE SERVICE BRAKE FOR THE TURN, PEDAL WENT TO FLOOR, NO BRAKES. LUCKILY NO INCIDENT. EXAMINED THE UNDERNEATH AND FOUND THAT THE STEEL BRAKE LINES WERE ROUTED OVER THE FRAME ON THE DRIVER SIDE (UNDERNEATH BODY UNDER THE DRIVER DOOR.) WHEN BRAKE LINE(S) FAILED, THERE WERE NO SIGN OF ANY BRAKING ABILITY. BOTH THE FRONT AND REAR BRAKE SYSTEMS WERE INOPERABLE. THE LINES HAD RUSTED THROUGH FROM APPARENTLY ROAD SALT OR (?), CREATING A VERY DANGEROUS SITUATION. SINCE THE INCIDENT I HAVE SPOKE WITH SEVERAL OTHER DRIVERS WHO HAVE EXPERIENCED THE SAME FAILURE. *TR

I WAS I 91 SOUTH HEADING IN TO HARTFORD CT, TRAFFIC WAS HEAVY AND AS A RESULT I WAS TRAVELING APPX 20 MPH AS I ENTERED THE RAMP EXIT LANE. I STEPPED ON BRAKE PEDAL AND THE PEDAL WENT TO THE FLOOR, FORTUNATELY I WAS ABLE TO VEER INTO THE BREAKDOWN LANE AND AVOID HITTING OTHER CARS. I SLOWLY MADE IT TO MY PLACE OF EMPLOYMENT AND LATER HAD THE TRUCK TOWED HOME. AS IT TURNS OUT I DISCOVERED THE ALL BRAKE LINES HAD CORRODED AND HAD TO BE REPLACED. I CONTACTED GM AS I THOUGHT IT VERY UNUSUAL FOR ALL BRAKES LINES TO BE SO SEVERELY CORRODED. THEY ATTRIBUTED THE SEVERE CORROSION TO THE FACT THAT THE TRUCK WAS 10 YEARS OLD AND REFUSED TO COVER THE EXPENSE AND CONSIDERED THE CASE CLOSED. BY DOING A SIMPLE INTERNET SEARCH I FOUND THAT THIS SAME PROBLEM IS QUITE COMMON AND MY MECHANIC ALSO INFORMED THAT GM ( POSSIBLY AS A RESULT OF THIS BEING A COMMON ISSUE) HAS MADE A AVAILABLE A BRAKE LINE REPLACEMENT KIT. *TR

AFTER EXITING ONTO THE HIGHWAY AND ATTEMPTING TO BRAKE TO MAKE A RIGHT TURN I EXPERIENCED CATASTROPHIC BRAKE FAILURE. WHEN THE BRAKE PEDAL WAS APPLIED THERE WAS NO PRESSURE, AND THE PEDAL WENT STRAIGHT TO THE FLOOR. NO WARNING LIGHTS OR SENSORS WERE ACTIVATED BEFORE THE TOTAL BRAKE FAILURE. THE VEHICLE WAS TOWED TO A LOCAL GMC DEALERSHIP. THE DEALERSHIP ADVISED ME THAT THE BRAKE LINE "BLEW OUT" FROM THE FRONT LEFT CALIPER BECAUSE OF RUST. I RESEARCHED SUCH PROBLEMS AND FOUND THAT SIMILAR COMPLAINTS WERE NUMEROUS AND THAT THE NHTSA HAD INITIATED AN INQUIRY/INVESTIGATIONS INTO EXCESSIVE RUST ON BRAKE COMPONENTS OF GMC VEHICLES CAUSING THIS TYPE OF TOTAL BRAKE FAILURE. *TR

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

Mileage: 82,000

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

Mileage: 94,000

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

I WAS LEAVING MY DRIVEWAY AND COMPLETELY LOST ALL BRAKES AND COULD NOT STOP. I HAD TO SLAM ON THE PARKING BRAKE TO STOP. A BRAKE LINE BLEW. ALL THE BRAKE LINES AND FUEL LINES ARE COMPLETELY ROTTED.THIS VEHICLE ISN'T EVEN 10 YEARS OLD YET. THE FUEL LINE AND BRAKE LINES ARE A MAJOR SAFETY ISSUE. THIS TRUCK IS A 2500 AND I USE IT FOR TOWING TRAILERS IF THAT BRAKE LINE WENT WHILE TOWING IT WOULD HAVE BEEN A MAJOR ACCIDENT. THE ENTIRE UNDERNEATH OF THIS TRUCK IS SO RUSTED THE FRAME BRAKE LINE AND FUEL LINES ARE TERRIBLE. SOMEONE IS GOING TO GET KILLED FROM GM'S CHEAP STEEL. *TR

ALL BRAKE LINES ARE RUSTED ABOUT INTO... ONE BUSTED, I HAD BEEN ON INTERSTATE FOR TWO HOURS AND LUCKILY I PULLED INTO MY DRIVEWAY AND LOST ALL BRAKES. BRAKE LINES SHOULD NOT BE IN SUCH A RUSTED STATE FOR THIS TRUCK, GM SHOULD BE MADE TO RECALL FOR THIS PROBLEM ... THIS IS LIFE THREATENING UNDER SUCH CONDITIONS!

I WAS COMING DOWN A HILL NEAR MY HOME & TAPPED ON THE BRAKES TO SLOW DOWN. SUDDENLY ALARM BELLS STARTED DINGING, THE ENGINE WARNING LIGHT CAME ON & "SERVICE BRAKES IMMEDIATELY" POPPED UP ON THE MESSAGE CENTER. THE BRAKE PEDAL WAS SLIGHTLY SOFTER THAN NORMAL BUT I MADE IT HOME OK. THE FOLLOWING DAY I TOOK THE TRUCK TO MY MECHANIC TO HAVE HIM CHECK OUT THE PROBLEM. MUCH THE SAME AS MANY OTHERS HAVE COMPLAINED ABOUT, ALL FOUR BRAKE LINES BETWEEN THE MASTER CYLINDER & THE ABS CONTROLLER WERE BADLY RUSTED OUT WHILE ONE HAD FAILED COMPLETELY (CAUSING THE ALERT/ALARM). THE LINES FROM THE ABS CONTROLLER TO THE INDIVIDUAL WHEELS ARE ALSO COMPLETELY RUSTED BUT AS OF NOW HAVEN'T FAILED. HE REPLACED THE ONE RUPTURED LINE & SUGGESTED THAT I HAVE THE OTHERS DONE AS SOON AS POSSIBLE AS THEY ALL LOOK VERY BAD. LOOKING AT THE UNDERCARRIAGE OF THE VEHICLE THERE WAS VERY LITTLE OVERALL RUST ON ANY OTHER COMPONENTS OR THE FRAME, JUST ON THE BRAKE LINES. ESTIMATED COST FOR REPLACING ALL THE LINES AS NEEDED - $800. *TR
