TL* THE CONTACT OWNS A 2004 GMC SIERRA 1500. THE CONTACT STATED THAT HE HAD TO TURN THE IGNITION SWITCH VARIOUS TIMES IN ORDER FOR THE VEHICLE TO START. THE VEHICLE WAS NOT TAKEN TO A DEALER FOR DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 62,000. THE CURRENT MILEAGE WAS APPROXIMATELY 70,000. UPDATED 05/28/14 MA

BRAKE FLUID LINE RUSTED COMPLETELY THROUGH. LOST BRAKES WITH FAMILY IN TRUCK WHILE AT 45 MILES AN HOUR AND THREE (3) MILES FROM HOME. DROVE HOME ON SHOULDER OF ROAD WITH DRAG ON TRANSMISSION TO STOP. VERY DISAPPOINTED THAT THIS HAS NOT BE RECALLED SOONER. *TR

THE GAUGES BEGAN TO SPIN AND NOT WORK PROPERLY OR NOT FUNCTION AT ALL. ALSO THE BRAKE LIGHTS DO NOT FUNCTION WHEN THE GAUGES AND DASH LIGHTS FLASH OR REMAIN ON. THE ABS LIGHT BRAKE LIGHT AND THE BATTERY LIGHT AND THE SECURITY LIGHT ALL COME ON. ALSO ALONG WITH ALL THE OTHER PROBLEMS WHEN ALL THIS HAPPENS THE HEADLIGHTS DIM THE FOURWHEEL DRIVE DOESN'T FUNCTION AND THE VOLUME LEVEL ON THE STEREO CHANGES. *TR

ALL OF THE VEHICLE INSTRUMENT GAUGES GO INOPERATIVE INTERMITTENTLY WHILE DRIVING. I HAVE OWNED THIS VEHICLE SINCE NEW. THERE HAS BEEN A GM ACTION OF SORT ON THIS, OF WHICH I AM NOT SURE. HOWEVER, I WAS NEVER NOTIFIED AND CURRENTLY AM EXPERIENCING THE PROBLEM. WE TOOK THE VEHICLE TO A GM DEALERSHIP THEY SAID THE MAINTENANCE ACTION(WHATEVER IT IS) EXPIRED IN 2011. SO THE REPAIR IS TOTALLY UPON US TO FIX, SOME $540. *TR

TL* THE CONTACT OWNS A 2004 GMC SIERRA 1500. THE CONTACT WAS DRIVING 35 MPH WHEN THE BRAKES FAILED. THE VEHICLE WAS DRIVEN AT A LOW SPEED TO THE CONTACT'S RESIDENCE AND WAS NOT INSPECTED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE INCIDENT. THE APPROXIMATE FAILURE MILEAGE WAS 77,000.

CRACKED CYLINDER HEADS, ALSO KNOWN AS CASTECH HEAD CASTING #706 THESE HEADS CRACK ON THE ENGINE CAUSE ANTIFREEZE TO MIX WITH THE OIL AND DESTROY THE ENGINE, I HAVE CONTACTED GM AND THEY WILL DO NOTHING FOR ME, EVEN THOUGH THERE HAS BEEN LAWSUITS AND ITS A VERY WELL KNOWN PROBLEM WITH THE VORTEC 4.8 AND 5.3L GM ENGINE. *TR

WHILE BACKING IN DRIVEWAY, BRAKE PEDAL HIT THE FLOOR WITH NO PRESSURE. LOST ALL FLUID IN SYSTEM. 3 BRAKE LINE TO BREAK IN 4 YEARS. *TR

I WAS BACKING OUT OF MY GARAGE WHEN SUDDENLY THE BRAKE PEDAL WENT TO THE FLOOR. AFTER THE BRAKE PEDAL WENT TO THE FLOOR THE ABS BRAKE WARNING LIGHT AND SERVICE BRAKES LIGHT CAME ON. I WAS ABLE TO PUSH DOWN ON THE EMERGENCY BRAKE PEDAL BEFORE STRIKING MY OTHER TRUCK WHICH WAS PARKED BEHIND ME. BEING SOMEWHAT MECHANICALLY INCLINED, I SAW A LINE OF BRAKE FLUID ON THE GROUND IN FRONT OF THE TRUCK EXTENDING BENEATH IT. I LOOKED UNDERNEATH THE TRUCK, ALMOST DIRECTLY BELOW THE DRIVERS SEAT AND SAW A BUNDLE OF STEEL BRAKE LINES THAT WERE NOTHING BUT A SOLID MASS OF RUST AND DRIPPING BRAKE FLUID! THE RUSTING IS SO BAD THAT I CAN'T TELL WHETHER IT'S ONE OR ALL OF THE BRAKE LINES RUSTED THROUGH! SINCE I'M RETIRED (AND DON'T HAVE TO DRIVE IN BAD WEATHER) AND HAVE ANOTHER OLDER TRUCK I DRIVE MOST OF THE TIME, THE GMC HAS RARELY SEEN BAD WEATHER (I PURCHASED IT NEW) AND WHEN IT DID IT WAS ALWAYS PRESSURE WASHED (UNDERNEATH) AT THE CAR WASH IMMEDIATELY AFTER THE SNOW OR ICE HAD ENDED! MY BROTHER WHO IS A MECHANIC RECENTLY HAD TO REPLACE ALL THE RUSTED BRAKES LINES ON A 2005 CHEVY TRUCK. *TR

04 GMC SIERRA 1500 EXTENDED CAB FRONT STEEL BRAKE LINES CORROSION/RUSTED AND BURST CAUSED SUDDEN FLUID LEAKAGE AND FAILURE TO STOP PLACED ME IN A DANGEROUS/HAZARDOUS SITUATION. FINDING A RELIABLE SHOP, EXPENSIVE TOWING AND REPAIRS CAUSED TREMENDOUS BURDEN AND INCONVENIENCE. *TR

BRAKES WORKED PERFECTLY TO STOP VEHICLE ON A STEEP DOWNWARD HILL IN ORDER TO OPEN A GATE AT THE BOTTOM OF THE HILL OF MY DRIVEWAY. AFTER THE GATE WAS OPENED THE VEHICLE PROCEEDED DOWN THE HILL COASTING AND THERE WAS A TOTAL BRAKE FAILURE WHEN TRYING TO SLOW DOWN. THE PEDAL WENT TO THE FLOOR WITH NO BRAKES WHATSOEVER. THE VEHICLE CRASHED INTO A TREE TO AVOID GOING OVER A CLIFF. THE VEHICLE HAS BEEN WELL MAINTAINED WITH NO WARNING OF BRAKE FAILURE. FRONT AND REAR BREAKS FAILED AT THE SAME TIME. NO WARNING BRAKE LIGHT INDICATOR ON DASH EVER WENT ON. THIS OCCURRED ON MY PROPERTY AND DRIVER AND A PASSENGER WERE BOTH INJURED. BODY SHOP INDICATED THAT THE BRAKE LINES RUSTED OUT. THIS COULD HAVE BEEN A FATALITY IF THE FAILURE TOOK PLACE ON THE ROAD. *TR

FRAME RUST. *LN

I PURCHASED BRIDGESTONE DUELER ALENZA HL TIRES AT 42509 ON 06/10/2009 AND ON 04/10/2011 I HAD A SLOW LEAK AND WENT TO BRIDGESTONE DEALER FOR REPAIR BUT NOTICED CRACKING IN TREAD. I WAS TOLD THIS WAS NORMAL! IN MAY 2013 MY MECHANIC SAID THIS CRACKING WAS DRY ROT AND I VERIFIED WITH OTHER TIRE DEALER TRUCK HAD 70693 MILE. THIS IS A 65000 MILE TIRE AND I ONLY HAD 14000 MILES BEFORE CRACKING STARTED- THIS IS A SAFETY HAZARD. I DID NOT GO BACK TO BRIDGESTONE DEALER BECAUSE I WAS GIVEN INACCURATE INFO AND I BOUGHT MICHELIN INSTEAD. I CALLED BRIDGESTONE AND THEY TOLD ME THERE WAS NOTHING THEY COULD DO AND "HAVE A NICE DAY."!!!! GOOD LUCK IF YOU BUY THESE! *TR

THIS OCCURRED ON 8/13/2013 IN CENTRAL VIRGINIA AND THE TRUCK HAD 93461 MILES ON IT. WHILE MOVING MY 2004 GMC SIERRA 1500 TRUCK IN MY DRIVEWAY, MY BRAKE PEDAL WENT TO THE FLOOR BECAUSE THE REAR PASSENGER SIDE BRAKE LINE HAD BURST. THERE WAS NO WARNING LIGHT OR CHIME INDICATING A BRAKE SYSTEM ISSUE. THE DUAL MASTER CYLINDER SYSTEM ONLY PROVIDED ENOUGH BRAKING TO SLIGHTLY SLOW THE VEHICLE DOWN AND THE PARKING BRAKE DIDN'T HELP MUCH. I HAD IT TOWED TO A SHOP AND THEY SAID IT WAS DUE TO A CORRODED STEEL BRAKE LINE. THEY TOLD ME THAT THEY HAVE HAD TO REPLACE THESE LINES FREQUENTLY IN A LARGE NUMBER OF CHEVROLET AND GMC PICKUP TRUCKS. THEY REPLACED THE LINE AND I HAD PLANNED TO REPLACE ALL OF THE OTHER LINES IN A FEW MONTHS. TWO WEEKS AFTER THE REPAIR WAS DONE AND APPROXIMATELY 50 MILES LATER, ANOTHER LINE FAILED WHILE I WAS DRIVING APPROXIMATELY 45 MPH. AGAIN, THERE WAS NO WARNING LIGHTS OR CHIMES AND THE PEDAL WENT TO THE FLOOR. I ESTIMATE THAT THERE WAS APPROXIMATELY 5 TO 10% BRAKING POWER AND WAS UNABLE TO STOP THE VEHICLE. THE PARKING BRAKE DID HELP SOME BUT IS NO A SUBSTITUTE FOR A REAL EMERGENCY BRAKE THAT THE OLDER VEHICLES USED TO HAVE. ADDITIONALLY, IT IS NOT EASY TO LIFT YOUR FOOT UP TO IT AS THE PEDAL IS MOUNTED SOMEWHAT HIGH OFF THE FLOOR. THE REPAIR SHOP SAID THAT THIS TIME IT WAS A STEEL LINE RUNNING TO THE MASTER CYLINDER AND COULD BE SEEN LEAKING FLUID FROM INSIDE THE ENGINE COMPARTMENT. I HAD THEM REPLACE ALL THE LINES. I DON'T UNDERSTAND WHY THE NHTSA HASN'T DEMAN

I WAS PARKING OUR 2004 GMC SIERRA PICK UP TRUCK WHEN MY FOOT WENT RIGHT TO THE FLOOR. AFTER GETTING OUT OF THE TRUCK, I NOTICED ALL THE BRAKE FLUID DRAINING OUT OF THE BRAKE LINE ON TO THE GROUND. WHEN OUR MECHANIC LOOKED AT IT, HE SAID ALL THE BRAKE LINES WERE RUSTED OUT AND THAT THE WHOLE UNDERCARRIAGE OF THE TRUCK WAS ENTIRELY RUSTED OUT. WHAT A DISGRACE. *TR

TL* THE CONTACT OWNS A 2004 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 5 MPH UPHILL, THE BRAKE PEDAL WAS DEPRESSED WITHOUT ANY RESPONSE FROM THE VEHICLE. THE EMERGENCY BRAKE WAS ENGAGED IN ORDER TO STOP THE VEHICLE FROM ACCELERATING ANY FARTHER. THE CONTACT PARKED THE VEHICLE AND NOTICED THAT THE BRAKES LINES WERE COMPLETELY CORRODED DUE TO EXCESSIVE RUST. IN ADDITION, BRAKE FLUID WAS LEAKING. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC AND REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 60,600.

GOT IN MY CAR AND PROCEEDED TO GO DOWN THE ROAD I WAS DOING ABOUT 45 MILES AN HOUR I HIT THE BRAKES TO SLOW DOWN AND THE BRAKE PEDAL WENT THE WHOLE WAY TO THE FLOOR AFTER I GOT STOPPED AND CHECKED IT OUT THE BRAKE LINES ARE COMPLETELY RUSTED THROUGH. *TR

INCIDENT #1 WHILE TRAVELING AT 50 MPH ON A COUNTRY ROAD I APPLIED BRAKES TO DECELERATE FOR A 75 DEGREE RIGHT HAND BEND IN THE ROAD. THE BRAKE PEDAL WENT TO THE FLOOR. I HAD TO COLUMN SHIFT DOWN THROUGH THIRD, SECOND, AND THEN TO FIRST GEAR, TO SLOW DOWN. I WAS UNABLE TO GET TO EMERGENCY BRAKE. FORTUNATELY IT WAS ON A LIGHTLY TRAVELED ROAD AND THERE WAS NO ON COMING TRAFFIC AS I HAD TO VEER INTO THAT LANE TO MAKE THE TURN. I WAS ABLE TO HOBBLE HOME, WITH HAZARDS ON, BY DOWNSHIFTING TO SLOW DOWN. THE TRUCK WAS TOWED TO LOCAL REPAIR SHOP. THE REAR BRAKE LINES HAD FAILED AND WERE REPLACED. INCIDENT #2 WHILE TRAVELING AT 30 MPH TRAVELING DOWN HILL A RACCOON RAN ACROSS THE ROAD. I APPLIED BRAKES IN A DEFENSIVE MANNER AND THE PEDAL WENT TO THE FLOOR. I AGAIN HAD TO COLUMN SHIFT THROUGH THIRD, SECOND, AND THEN HOBBLE DOWN HILL IN FIRST GEAR. I WAS UNABLE TO ENGAGE EMERGENCY BRAKE. I WAS ABLE TO HOBBLE HOME DOWN SHIFTING THROUGH THE GEARS. THE TRUCK WAS AGAIN TO SAME SHOP AND I HAD THEM REPLACE ALL BRAKE LINES. *TR

I WAS APPROACHING A STOP SIGN DRIVING APPROXIMATELY 45 MPH. WHEN I APPLIED THE BRAKES THE PEDAL WENT TO THE FLOOR, AND THE VEHICLE WOULDN'T STOP. I MANEUVERED PAST SEVERAL VEHICLES ALMOST STRIKING THEM. I WAS ABLE TO APPLY THE EMERGENCY BRAKE TO STOP THE VEHICLE AFTER SOME DISTANCE PAST THE INTERSECTION. I AM A POLICE OFFICER WITH 25 YEARS ON THE JOB. I HAVE ATTENDING VARIOUS DRIVING COURSES RELATED TO MY PROFESSION. IF A LAY PERSON WAS IN THIS SITUATION A SERIOUS ACCIDENT WOULD HAVE HAPPENED. I BARELY ESCAPED THE ACCIDENT DUE IN PART TO TRAINING AND A LARGE AMOUNT OF LUCK. ON THE DAY OF THE INCIDENT THE VEHICLE HAD STOPPED NORMAL AT THREE PRIOR INTERSECTIONS WITHOUT GIVING ANY WARNING OF A POTENTIAL PROBLEM. I HAVE READ ON LINE THE THEORY ABOUT THE SALT CAUSING THE DAMAGE TO THE BRAKE LINES. I HAVE NEVER DRIVEN THIS VEHICLE IN THE SNOW SINCE IT IS A SPARE VEHICLE. THE VEHICLE HAS 72000 MILES A LARGE MAJORITY OF THOSE MILES DRIVEN ON THE HIGHWAY (SUMMER AND FALL). I BOUGHT THIS VEHICLE NEW FROM THE DEALERSHIP IN 2004. THE COST TO REPAIR THE BRAKE LINES WAS $1,100 DOLLARS. A RECALL SHOULD BE MADE IN REGARDS TO THIS DEFECT BEFORE SOMEONE IS KILLED OR SERIOUSLY INJURED. I HAD A MECHANIC SHOP REPAIR THE VEHICLE SINCE THE DEALERSHIP CLAIMED THEY HAD NO OTHER REPORTED FAILURES ON THIS VEHICLE. A QUICK LOOK ON VARIOUS WEBSITES SHOWED THAT TO BE A FALSE CLAIM. ANYONE DRIVING THESE TYPES OF VEHICLES PLEASE HAVE YOUR BRAKE LINES INSPECTED BY A MECHANIC. *TR

TL*THE CONTACT OWNS A 2004 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE THE BRAKE PEDAL WAS DEPRESSED, THE ABS SYSTEM ACTIVATED WITHOUT WARNING. THE VEHICLE WAS NOT TAKEN TO THE DEALER TO HAVE A DIAGNOSED PERFORMED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 97,000 AND THE CURRENT MILEAGE WAS 98,000.

WHILE EXITING THE HIGHWAY DRIVER PRESSED BRAKE PEDAL WHICH SANK ALL THE WAY TO THE FLOOR WITH APPROX 5 PERCENT BRAKING POWER. DRIVER LIFTED OFF AND REAPPLIED THE BRAKES IN AN ATTEMPT TO FIX PROBLEM AT THIS POINT A DASH LIGHT AND ALARM ILLUMINATED TO WARN OF BRAKE ISSUES; BRAKING POWER WAS STILL ONLY 5 PERCENT. DRIVER WAS ABLE TO STOP BEFORE AN ACCIDENT OCCURRED BUT ONLY BECAUSE OF LIGHT TRAFFIC AND PLENTY OF RUN OFF AREA. UPON INSPECTION OF VEHICLE IT WAS EVIDENT THAT THE BRAKE LINES HAD CORRODED AND RUPTURED UNDER THE DRIVERS DOOR. VEHICLE WAS TAKEN TO DEALERSHIP WHERE 6 BRAKE LINES WERE REPLACES DUE TO CORROSION. VEHICLE WAS NOT DRIVEN IN NORTHERN WINTERS AND HAS NOT BEEN ON ANY BEACHES. *TR

WHILE COMING TO AN INTERSECTION THE BRAKES WERE APPLIED AND THE PEDAL BECAME SOFT AND WHEN TO THE FLOOR, WITHOUT SLOWING THE VEHICLE DOWN. THE TRANSMISSION WAS SHIFTED INTO NEUTRAL AND THE EMERGENCY/PARKING BRAKE WAS APPLIED IMMEDIATELY IN ORDER TO STOP THE VEHICLE. THE VEHICLE WENT TO THE LOCAL DEALERSHIP WHERE THE DIAGNOSIS WAS A BRAKE LINE HAD RUPTURED DUE TO CORROSION (RUST) ON THE DRIVER SIDE REAR LINE. THE OTHER THREE LINES WERE IN A SIMILAR STATE AND HAD THE POTENTIAL TO FAIL AT ANY TIME. THERE WAS NO INDICATION ON THE MESSAGE CENTER THAT THERE WAS EVER INADEQUATE PRESSURE TO STOP THE VEHICLE WITH THE HYDRAULIC BRAKE SYSTEM EVEN WHEN IT WAS STEERED TO THE SIDE OF THE ROAD AND THE BRAKE PEDAL WAS APPLIED TO PUT THE TRANSMISSION INTO PARK. *TR

THE BRAKE LINES ON MY TRUCK ROTTED OFF AND IT COST OVER A GRAND TO FIX THEM. THERE SHOULD BE A RECALL. *TR

TL* THE CONTACT OWNS A 2004 GMC SIERRA 1500. THE CONTACT STATED THAT THE BRAKE LINES WERE DETERIORATING AND THE MATERIAL WAS RUSTED. AS A RESULT, BRAKE FLUID WS CONSTANTLY LEAKING AND THE BRAKES HAD BECOME HARD TO ENGAGE. THE VEHICLE WAS NOT TAKEN TO THE DEALER OR A PRIVATE MECHANIC. THE MANUFACTURER WAS NOTIFIED WHO STATED THAT THERE WERE NO RECALLS FOR THE VEHICLE AND OFFERED NO ASSISTANCE. THE VIN WAS NOT AVAILABLE. THE FAILURE AND THE CURRENT MILEAGE WAS 78,000.

EXHAUST MANIFOLD BOLTS BROKE OFF CAUSING THE DRIVERS SIDE HEAT SHIELD TO FALL AND JAM UNDER THE STEERING LINKAGE. THIS CAUSED ME TO ALMOST DRIVE OFF THE ROAD. I HAD TO FORCE THE STEERING WHEEL TO GET THE VEHICLE TO TURN. *TR

REGARDLESS OF TYPE OF ROAD, I.E. HIGHWAY OR CITY ROADS, AND REGARDLESS OF SPEED, THE VEHICLE WILL STALL AND SHUT OFF. *TR

VEHICLE WOULD STALL AND EVENTUALLY SHUT OFF, REGARDLESS OF TYPE OF ROAD, I.E.HIGHWAY OR CITY STREETS, AND REGARDLESS OF THE SPEED. *TR

VEHICLE WOULD STALL AND EVENTUALLY SHUT OFF, REGARDLESS OF TYPE OF ROAD, I.E.HIGHWAY OR CITY STREETS, AND REGARDLESS OF THE SPEED. *TR

ALL OF THE BRAKE LINES BELOW DRIVERS SIDE DOOR BECAME EXTREMELY RUSTED, THUS BUSTING AND RELEASING ALL THE BRAKE FLUID AT ONCE, LEAVEINGTHE VEHICLE INOPERATIVE. *TR

TL* THE CONTACT OWNS A 2004 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE APPROACHING A TRAFFIC STOP, HE ATTEMPTED TO ENGAGE THE BRAKES BUT THE PEDAL WAS DEPRESSED INTO THE FLOORBOARD ABNORMALLY. IN ADDITION, THE CONTACT APPLIED THE EMERGENCY BRAKE TO NO AVAIL. THE CONTACT STATED THAT IN ORDER TO STOP THE VEHICLE, HE HAD TO DRIVE THE VEHICLE ALONGSIDE THE SIDEWALK. AFTER INSPECTING THE VEHICLE, HE DISCOVERED THAT THE BRAKE LINES WERE COMPLETELY CORRODED. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE AND THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 80,000.

TL* THE CONTACT OWNS A 2004 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 50 MPH AND DEPRESSING THE BRAKES, THERE WAS AN ABNORMAL INCREASE IN STOPPING DISTANCE AND TIME. THE VEHICLE HAD NOT BEEN INSPECTED BY A DEALER NOR REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE WAS APPROXIMATELY 15 AND THE CURRENT MILEAGES WERE APPROXIMATELY 61,000.

WHEN THE WEATHER IS BELOW FREEZING THE TURN SIGNALS DO NOT WORK UNTIL THE VEHICLE HAS WARMED UP FOR ATLEAST 20 MINUTES. ALSO THE SPEEDOMETER DOES NOT WORK, AND WHEN IT DOES START WORKING IT IS NEVER THE CORRECT READING. IT WILL STICK AS HIGH AS 70 MPH, AND TO BRING IT DOWN I HAVE TO KEEP RESTARTING AND SHUTTING OFF THE ENGINE. *TR

I OWN A 2004 GMC K1500 WITH ABOUT 70000 MILES ON IT NOW. ON 10/17/11 AT 67410 MILES I WAS DOING A NORMAL OIL CHANGE WITH THE VEHICLE ELEVATED ON A RACK. I NOTICED FLUID DRIPPING ON ME FROM UNDER THE DRIVERS FLOOR AREA. UPON CLOSER INSPECTION I FOUND ALMOST ALL OF THE BRAKE LINES LEADING FROM THE FRONT OF THE TRUCK TO THE ABS UNIT RUSTED BADLY AND LEAKING. AS I WAS MOVING THE VEHICLE FROM THE RACK THE BRAKE PEDAL WENT TO THE FLOOR. WITH VERY CAREFUL OPERATION AND USING THE PARKING BRAKE I WAS ABLE TO GET THE TRUCK BACK ON LEVEL GROUND. I REPLACED ALL THE LINES LEADING FROM THE ABS UNIT TO THE FRONT OF THE TRUCK REROUTING THEM ALONG THE FRAME. IF THIS FAILURE HAD OCCURRED ON THE HIGHWAY OR WHILE PULLING MY TRAILER A SERIOUS ACCIDENT MAY HAVE RESULTED. THIS PROBLEM IS A MANUFACTURING/ENGINEERING DEFECT IN MANY OF THESE VEHICLES. YOU SHOULD NOT LOSE ALL OF YOUR BRAKES WHEN A LINE RUPTURES. THE DUAL MASTER CYLINDER SHOULD ALLOW YOU TO HAVE BRAKES ON THE OPPOSITE SIDE, GM SHOULD RECALL THESE VEHICLES AND REPLACE THE BRAKE LINES WITH STAINLESS OR ANOTHER ENGINEERING FIX. *TR

FUEL TANK HAS RUSTED STEEL SUPPORT STRAPS; REAR STRAP BROKE AND TANK DROPPED A FEW INCHES PLACING ADDITIONAL PRESSURE ON RUSTED FRONT SUPPORT STRAP. TANK WOULD BOUNCE UP AND DOWN DUE TO BUMPS IN ROAD. FORTUNATELY MY FRIEND, FOLLOWING MY TRUCK, ALERTED ME AND WE SECURED TANK WITH A LENGTH OF ROPE. HAD HE NOT ALERTED ME IT IS LIKELY FRONT STRAP WOULD HAVE FAILED, DROPPING TANK ONTO PAVEMENT. THE DEFECT WAS NOTED JUST BEFORE I WAS ABOUT TO PROCEED ONTO INTERSTATE 93. HAD THE FRONT STRAP FAILED, THE FUEL TANK WOULD HAVE DRAGGED FOR A DISTANCE AT HIGH SPEED, POSSIBLY CAUSING AN EXPLOSION/FIRE. THIS IS THE FIRST TIME I HAVE EVER HAD A FUEL TANK DISLODGE AND I NORMALLY KEEP VEHICLE FOR 150,000 MILES AND 10 YEARS. HIGHLY RECOMMEND VEHICLES WITH STEEL FUEL TANK SUPPORT STRAPS BE RECALLED FOR INSPECTION; IN NORTHEAST WHERE SALT IS USED ON HIGHWAYS, STEEL ON THE UNDERCARRIAGE OF A VEHICLE WILL RUST. FUEL TANK SUPPORT STRAPS SHOULD BE MADE OF STAINLESS STEEL OR ANOTHER MATERIAL THAT IS NOT SUBJECT TO DEGRADATION/CORROSION DUE TO ROAD SALT. OCCUPANTS OF VEHICLES, FIRST RESPONDERS AND OTHERS ARE AT RISK DUE TO THIS DESIGN FLAW. *TR

SPEEDOMETER FLUTTERS AND NOW GIVES ERRONEOUS READING, GAS GAUGE GIVES FALSE READINGS. I DID SOME ONLINE RESEARCH AND FOUND THAT THERE WAS A PROBLEM WITH THE INSTRUMENT PANEL CLUSTER AND A LETTER WAS SENT BY GMC. I AM THE ORIGINAL OWNER AND NEVER RECEIVED A LETTER AND NOW MY INSTRUMENT CLUSTER IS FAILING. AND NOW AM PAST MILEAGE/YEARS TO FIX, BECAUSE I NEVER GOT THE ORIGINAL LETTER AND NEVER NEW THERE WAS A PROBLEM. *TR

TL* THE CONTACT OWNS A 2004 GMC SIERRA 1500. THE CONTACT STATED THAT THE RADIATOR DID NOT HAVE A PEACOCK TO DRAIN ITS COOLANT FROM. AN AUTHORIZED DEALER WAS NOTIFIED AND THE CONTACT WAS INFORMED THAT THE MANUFACTURER STOPPED USING PEACOCKS TO SAVE MONEY. THE CONTACT EXPRESSED CONCERN OVER THE SITUATION BECAUSE IT COULD LEAD TO A FAILURE OF THE RADIATOR. THE FAILURE AND CURRENT MILEAGES WERE 28,000. THE VIN WAS UNAVAILABLE. I WAS INFORMED THAT THE LOWER RADIATOR HOSE MUST BE REMOVED TO CHANGE COOLANT. IN DOING SO THE HOSE CAN BE DESTROYED AND COOLANT COULD BE SPILT ON THE GROUND. UPDATED 10/11/2011 *LN *TR

TL* THE CONTACT OWNS A 2004 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE DRIVING 20 MPH, HE HEARD A NOISE COMING FROM THE ENGINE. THE VEHICLE WAS TAKEN TO THE LOCAL MECHANIC, WHO STATED THAT THE FAILURE WAS DUE TO THE CYLINDER HEADS BEING CRACKED, CAUSING THE ENGINE TO LOSE OIL AND COOLANT. THE LOCAL MECHANIC REPLACED THE CYLINDER HEADS, THE GASKET KIT, BOLTS AND NUTS. THE MANUFACTURER DENIED ASSISTANCE WITH THE REPAIRS. THE FAILURE MILEAGE WAS 78,000 AND THE CURRENT MILEAGE WAS 79,520.

I GOT INTO MY 2004 GMC SIERRA 1500 PICKUP TRUCK AND WENT TO STOP. THE PETAL WENT TO THE FLOOR. I DISCOVERED THE BRAKE LINES WERE RUSTED AND CREATED A LEAK CAUSING LOSS OF THE BRAKES. THE VEHICLE HAS NO RUST IN ANY OTHER AREAS. IT IS OBVIOUS THE BRAKE LINES WERE CORRODED WELL BEFORE THE NORMAL LIFE OF VEHICLE BRAKES. I WAS ABLE TO STOP THE VEHICLE BEFORE AN ACCIDENT WAS CAUSED DUE PRIMARILY TO MY EXPERIENCE AS A LONG TIME POLICE OFFICER. THIS TYPE OF BRAKE FAILURE COULD CAUSE ACCIDENTS AND FATALITIES. *KB

I HEAR A TAPPING OF THE VALVES WHEN THE CAR IS ON. ALSO THE SPEEDOMETER WILL STOP REGISTERING HOW FAST I AM GOING. *TR

TL* THE CONTACT OWNS A 2004 GMC SIERRA 1500. THE CONTACT WAS DRIVING APPROXIMATELY 30 MPH WHEN THE VEHICLE EXHIBITED AN ABNORMAL RATTLING FROM THE STEERING WHEEL.

THE MANUFACTURER WAS CONTACTED AND STATED THAT THE PART HAD BEEN REPLACED AND THEY COULD NOT OFFER ANY FURTHER ASSISTANCE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 26,000.

I HAVE A 2004 GMC SIERRA 1500. I AM HAVING SEVERAL PROBLEMS WITH THE INSTRUMENT PANEL, SPEEDOMETER NOT READING PROPERLY, TEMP GAUGE WRONG READINGS. THE DEALERS WANT $750.00 TO REPAIR IF THE VEHICLE IS OVER 75,000 MILES. THEY HAVE SAID THEY SENT RECALL INFORMATION FOR THIS PROBLEM, I HAVE NEVER RECEIVED ANYTHING OF THE SORT. FOR A VEHICLE I PAID 32, 000 FOR I FIND THIS TO BE UNSAT. GMC NEEDS TO FIX THIS PROBLEM FREE OF CHARGE FOR THERE CUSTOMERS, I WOULD EXPECT THIS TREATMENT FROM A FORD DEALER. *TR

IN MY 2004 GMC SIERRA THE WIRING HARNESS FOR THE A/C DOWN NEAR THE PASSENGER FLOORBOARD SMOKES AND I SMELL BURNING PLASTIC AND MY A/C DOESN'T WORK AND I TALKED TO A FEW OTHER GMC AND CHEVY OWNERS AND THEY HAVE THE SAME PROBLEM.

ON MY 2004 GMC SIERRA 1500 NOV 10, 2010 THE SPEEDOMETER JUST QUIT WORKING WHILE BACKING OUT THE YARD IT JUMPED UP TO 70MPH AND NOW THIS HAPPENED AND THE RPM METER IS STUCK AT 0 ALSO COULD THIS BE A SERIOUS PROBLEM BECAUSE MY WIFE USE THIS VEHICLE TO DRIVE TO WORK. *TR

2004 GMC SIERRA EXT CAB WITH 40K MILES HAS SERIOUSLY DEGRADED BRAKING POWER. UPON SUDDEN STOPS THE VEHICLE WASN'T TO KEEP ROLLING TAKING FAR TO LONG TO STOP. THE PEDAL GOES ALMOST TO THE FLOOR AND YET THE TRUCK IS STILL MOVING. THE ABS SYSTEM DOES NOT INDICATE IT IS WORKING BUT THE WHEEL S DO NOT LOCK UP TO A SKID, IN FACT, I CAN'T GET THE TRUCK TO SKID OR INVOKE THE ABS SYSTEM NO MATTER WHAT I DO. I CALLED THE DEALER WHO SAID NO RECALLS WERE OUT FOR THIS PROBLEM BUT THIS IS DEFINITELY NOT RIGHT. DEALER SAYS IT'S NORMAL BUT I CAN BRING IT IN FOR AN INSPECTION ( $100) BUT ANY REPAIRS ARE NOT COVERED BY GM, HE ACTED LIKE HE NEVER HEARD OF THIS BEFORE? I HAVE HEARD OF SEVERAL OTHER GMC TRUCK OWNERS THAT SAID THEY HAD SIMILAR ISSUES ONLY TO BE CHARGED $800 OR MORE WITH LITTLE IMPROVEMENT. I CANNOT KEEP THIS TRUCK LIKE THIS, I AM AFRAID I WILL ROLL INTO THE BACK OF SOMEONE AND I CANNOT TOW MY TRAILER ( SMALL BIKE TRAILER) FOR FEAR OF THE SAME. WHEN WILL GM WAKE UP? *TR

KNOCKING IN THE STEERING SHAFT ASSEMBLY BEGAN AT 20,000 MILES. STEERING SHAFT HAS TO BE GREASED BY SERVICE CENTER EVERY 10K MILES TO PREVENT KNOCKING. SPEEDOMETER, ODOMETER, AND ENGINE TEMPERATURE GAUGES STOPPED WORKING. SPEEDOMETER USED TO REGISTER MAX MPH WHEN DOING 70MPH THEN STOPPED WORKING AT ALL. *TR

AIR BAG SENSOR ICON STAYS ON SHOWING A PROBLEM WITH THE FRONT PASSENGER AIRBAG. DON'T KNOW WHAT THAT MEANS OTHER THAN THE AIR BAG IS CONTINUALLY OFF NO MATTER WHAT YOU DO, ON THE PASSENGER SIDE. VEHICLE WAS NOT IN A WRECK OR CRASH OR FIRE. IT JUST CAME ON BY ITSELF A COUPLE OF MONTHS AGO AND CAN;T BE MADE TO GO AWAY AND HAS STAYED ON CONSTANTLY. MY CONCERN IS THE PASSENGER SEAT IS NOT COVERED BY AN AIR BAG IN CASE OF A CRASH . DEALER SAID AIR BAG SENSOR IS NOT COMMUNICATING WITH THE COMPUTER. SENSOR IS $900.00 TO REPLACE. THERE ARE MANY COMPLAINTS ABOUT THIS SAME PROBLEM ONLINE WITH OTHER GMC SIERRAS PICK UPS AND GMC VEHICLES. THERE IS A PROBLEM HERE. CAN YOU HELP? *TR

I HAVE A 2004 GMC SIERRA PICKUP AND THE SPEEDOMETER BROKE ABOUT 4 MONTHS AGO. CAN ANYTHING BE DONE BY THE COMPANY THAT WONT COST ME OVER 400 DOLLARS. *TR
