2004 GMC SIERRA 1500 Complaints

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
