GOING DOWN THE ROAD PULLING A TRAILER, WENT TO BRAKE AND THE BRAKES WENT TO THE FLOOR. ENDED UP HAVING TO USE THE TRAILER BRAKES TO STOP. *TR

FIRST INCIDENT WAS A BRAKE LINE BURSTING IN MY DRIVEWAY. I HAD IT REPAIRED AT MY LOCAL GARAGE. AT THAT TIME HE TOLD ME THAT ALL OF THE BRAKE LINES WERE IN BAD SHAPE. SECOND INCIDENT, WHILE I WAS DRIVING UP THE ROAD AT APPROX 55 MPH WITH MY 19' BOAT IN TOW I REALIZED I HAD NO STEERING OR BRAKES. I WAS ABLE TO COAST TO A STOP AND PULL THE VEHICLE OFF THE ROAD TO A SAFE LOCATION. THE FAILURE WAS ATTRIBUTED TO A ROTTED LINE TO THE POWER STEERING COOLER. LASTLY, I AM NOT ABLE TO GET A SAFETY INSPECTION STICKER BECAUSE MY BRAKE LINES IN SUCH BAD CONDITION. ESTIMATED COST TO REPAIR $800-$1500 DOLLARS. I WILL ADD THAT THE TRUCK LOOKS LIKE NEW, SPENDS MOST OF IT'S TIME IN THE GARAGE AND IS USED PRIMARILY TO GO TO THE LOCAL DUMP, PLOW MY DRIVEWAY ONLY AND OCCASIONALLY TOW MY BOAT TO THE LAKE! MILEAGE REFLECTS THIS.DATES MAY NOT BE TOTALLY ACCURATE BUT THE BEST OF MY RECOLLECTION. *TR

DUE TO CORROSION THE BRAKES LINE BURST CAUSING A COMPLETE BRAKING FAILURE - NO WARNING LAMPS ILLUMINATED!!! THE LINES CORRODED COMPLETELY IN THE HOLDERS WHICH ATTACH TO THE VEHICLES FRAME. UNDER MODERATE STOPPING PRESSURE THE LINES BURST! ALL METAL LINES NEED TO BE REPLACED FROM THE FRONT OF THE VEHICLE TO THE REAR. TRUCK HAS NEVER BEEN EXPOSED TO EXTREME WEATHER OR SALT WHILE IN MY OWNERSHIP. THIS IS COMPLETELY AND UTTERLY UNACCEPTABLE. *TR

TRUCK WAS ENTERING MAJOR HIGHWAY,TRAFFIC BEGINS TOO SLOW DUE TO RUSH HOUR ,SEEING THIS OCCUR I STEPPED ON BRAKES EXPECTING TO SLOW DOWN ,UNTIL I REALIZED PEDAL HAD GONE ALL THE WAY TO FLOOR,THEN I LET UP AN PUSHED TO FLOOR AGAIN-NO BRAKES NO ROOM TO GO LEFT OR RIGHT IMPACT WAS UNAVOIDABLE,IMPACTED CAR TWICE WHICH PUSHED THAT CAR INTO ANOTHER THIS TRUCK WAS SERVICED BY GM DEALER FOR TRANSMISSION COOLING LINE AND ENGINE COOLING LINES MONDAY TUESDAY AND WEDNESDAY, NO MENTION OF BRAKE LINES ISSUE, ACCIDENT OCCURRED ON FRIDAY.

I WAS DRIVING DOWN MY STREET AND TRIED TO STOP AT THE STOP SIGN. THE BRAKE PEDAL STARTED TO STOP THE VEHICLE AND THEN SUDDENLY WENT STRAIGHT TO THE FLOOR. I DROVE THE ONE BLOCK BACK TO MY HOUSE AND PARKED THE VEHICLE. I OBSERVED A LARGE PUDDLE OF BRAKE FLUID UNDER THE DRIVERS DOOR. UPON INSPECTION, I SAW A BUNDLE OF RUSTY BRAKE TUBES RUNNING DOWN THE FRAME RAIL OF THE TRUCK. I HAD THE TRUCK TOWED TO MY MECHANIC. *TR

PUMPING UP BRAKES IN DRIVEWAY WHEN BRAKE LINE BURST ENDED UP WITH NO BRAKES AT ALL FRONT OR BACK COULD ONLY USE EMERGENCY BRAKES TO POSITION TRUCK TO BE TOWED. *JS

NOTICED A LARGE PUDDLE UNDER MY TRUCK IN THE DRIVEWAY. DISCOVERED IT WAS BRAKE FLUID THAT WAS LEAKING FROM RUSTED BRAKE LINES. I WAS TWO WEEKS FROM DRIVING FROM FLORIDA TO MID-MICHIGAN..THROUGH THE MOUNTAINS..PULLING A TRAILER. COST $340 TO GET IT REPAIRED NOT REPLACED. *TR

TL* THE CONTACT OWNS A 2003 GMC SIERRA DENALI. WHILE DRIVING 35 MPH, THE CONTACT HEARD A SQUEAKING SOUND IN THE REAR OF THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHO ADVISED THE CONTACT THAT THE REAR AXLE BEARING NEEDED TO BE REPLACED; HOWEVER, THE CONTACT WAS INFORMED BY THE DEALER THAT THE PART WAS NOT BEING MANUFACTURED AND THE FAILURE COULD NOT BE REPAIRED. THE CURRENT AND FAILURE MILEAGES WERE 105,000.

2003 GMC SIERRA PICK-UP 4WD EXTENDED CAB. BRAKE LINE FAILURE DUE TO CORROSION. DATE OF FAILURE 2/27/12 MILEAGE 23068 COST OF REPAIR $1283.82. MY NEIGHBOR HAS A 2004 GMC AND ALSO NEED TO REPLACE HIS BRAKE LINES. *TR

AT 81,000, MILES THE REAR STEEL BRAKE LINE FROM THE FRAME TO THE REAR END RUSTED OUT AND BURST. AT 83000, MILES 3 OF THE STEEL BRAKE LINES, LOCATED UNDER THE DRIVERS DOOR AREA AT THE LEFT FRAME RAIL IN A BUNDLE OF 6 LINES, RUSTED OUT AND BURST. LUCKILY I WAS ABLE TO STOP MY TRUCK EACH TIME BY USE OF THE PARKING BRAKE AND DID NOT CRASH. ALL THE STEEL BRAKE LINES ARE RUSTED VERY BADLY AND NEED REPLACING. MY LOCAL DEALER QUOTED ME $2270.00 DOLLARS TO REPLACE ALL THE LINES. *TR

BOUGHT THE TRUCK RECENTLY FROM VINCE WHIBBS GMC PENSACOLA FL. HAD SOME FRONT END WORK DONE BUT ALSO THERE IS A LOOSE STEERING SHAFT THAT IS A COMMON DEFECT WITH THIS YEAR AND MODEL TRUCK. WHILE CORNERING THE TRUCK AT LOW SPEEDS AND GOING OVER BUMPS THERE IS A LOOSE FEELING FELT IN THE STEERING. *TR

THE REAR BRAKE PADS SQUEALED & WERE GRINDING & THE TRUCK HAD VERY POOR STOPPING POWER. THE TRUCK WAS TAKEN TO MY MECHANIC & HE WAS DOING THE BRAKE JOB; HE REPLACED ALL FOUR ROTORS BECAUSE THEY WERE RUSTED BEYOND REPAIR. THE PADS WERE REPLACED AS WELL. WHILE HE WAS DOING THE BRAKES HE OBSERVED THE BRAKE LINES WERE RUSTED TO A POINT THAT IT ALARMED HIM & HE SAID THEY SHOULD BE CHANGED. HE ALSO COMMENTED THAT THE BRAKES HAD WORN VERY UNEVEN. THE FRONT PADS WERE BARELY WORN & WERE ONLY MAKING CONTACT AT A SMALL AREA OF THE ROTOR (ABOUT 1/2" OF THE FULL FACE ON THE ROTOR). THE BACK PADS & ROTORS WERE COMPLETELY WORN DOWN & THE ROTORS WERE RUINED. SOME OF THE AREAS UNDER THE TRUCK LOOK AS NEW & OTHER PLACES; MAINLY THE A-FRAMES, BRAKE LINES, SOME FRAME MEMBERS, ETC. LOOK LIKE THEY ARE 15 YEARS OR MORE OLDER. THE BRAKES WERE PUT BACK TOGETHER & NOW THEY ARE SO TIGHT & WON'T RELEASE THE ROTORS, CAUSING THE ROTORS TO OVER HEAT. I AM NOW HAVING HIM REPLACE THE BACK TWO CALIPERS WITH REPLACEMENT CALIPERS THAT USE PHENOLIC PISTONS RATHER THAN STEEL & ARE NOT GM PARTS. *KB

TL* THE CONTACT OWNS A 2003 GMC SIERRA. THE CONTACT WAS EXITING A DRIVEWAY AT 5 MPH WHEN THE BRAKES WERE APPLIED AND THE VEHICLE EXHIBITED AN ABNORMAL POPPING. THE CONTACT THEN REVERSED INTO THE DRIVEWAY AND UPON INSPECTING THE VEHICLE, DISCOVERED BRAKE FLUID WAS LEAKING FROM THE VEHICLE INTO A LARGE PUDDLE. HE THEN NOTICED THAT THE FOUR BRAKE LINES RUNNING ALONGSIDE THE FRAME WERE RUSTED, CAUSING THE LEAK. THE VEHICLE WAS TOWED TO A MECHANIC WHO INSPECTED THE FAILURE AND ADVISED THAT THE PARTS NEEDED FOR REPAIR WOULD ARRIVE IN ONE WEEK. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE.

MY 16 YR. SON WAS DRIVING HOME FROM WORK, WHEN HE LOST HIS BRAKES. FORTUNATELY HE IS A CAUTIOUS DRIVER AND WAS ABLE TO AVOID STRIKING THE VEHICLES IN FRONT OF HIM IN TRAFFIC. ALL OF THE BRAKE LINES ARE RUSTED. *TR

TOTAL BRAKE FAILURE WHILE DRIVING VEHICLE. HAD TO USE EMERGENCY PARKING BRAKE TO STOP. ALL BRAKE LINES ARE HEAVILY CORRODED AND COVERED IN RUST. BRAKE LINE THAT FAILED WENT TO RIGHT FRONT BRAKE. PIN HOLE IN BRAKE LINE COULD BE SEEN WHEN PUMPING BRAKES. FORTUNATELY BRAKES FAILED AT SLOW SPEED AND WAS ABLE TO STOP. I HAVE NEVER SEEN SUCH A BUILD UP OF RUST ON BRAKE LINES.

METAL BRAKE LINES RUPTURED DUE TO CORROSION. IT IS EVIDENT WHEN OTHER METAL UNDER BODY COMPONENTS ARE COMPARED TO THE BRAKE LINES THAT THE CORROSION IS EXCESSIVE. IT IS READILY APPARENT THAT INFERIOR ALLOYS WERE USED ON THIS VEHICLES BRAKE COMPONENTS. THE BRAKES FAILED WHILE THE VEHICLE WAS BEING BROUGHT TO A STOP. THESE SUBSTANDARD COMPONENTS CLEARLY REPRESENT A SAFETY HAZARD. I AM THE VEHICLES ORIGINAL OWNER AND IT HAS BEEN OPERATED IN THE NEW ENGLAND AREA AND MAINTAINED EXTREMELY WELL. *TR

THE BRAKE LINE RUPTURED CAUSING COMPLETE BRAKE SYSTEM FAILURE. LUCKILY I WAS IN MY DRIVEWAY AND ONLY TRAVELING VERY SLOW. I CAN SEE BRAKE FLUID PUDDLING UNDER THE DRIVER SIDE DOOR AREA. *TR

TL* THE CONTACT OWNS A 2003 GMC SIERRA. THE CONTACT STATED THAT THE VEHICLE FAILED TO ACCELERATE WHEN THE ACCELERATOR WAS DEPRESSED. THE VEHICLE WAS TOWED TO THE DEALER AND THE MANUFACTURER WAS CONTACTED, BUT THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 78,000 AND THE CURRENT MILEAGE WAS 79,059.

TL* THE CONTACT OWNS A 2003 GMC SIERRA. WHILE APPLYING THE BRAKES, THE BRAKE PEDAL WAS DEPRESSED STRAIGHT INTO THE FLOORBOARD. THE CONTACT STATED THAT THE DEFECT WAS A RESULT OF RUSTED BRAKE LINES. THE DEALER AND MANUFACTURER DENIED ANY ASSISTANCE WITH REPAIRS TO THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 76,667.

FAILED COMPONENT 1: DRIVING AT SLOW SPEED, REDUCED POWER LIGHT ENERGIZED AND ENGINES GOES TO IDLE SPEED WITH NO FUEL PEDAL RESPONSE. FAILED COMPONENT #2: EXHAUST MANIFOLD BOLTS IN CYLINDER HEADS BROKEN ON BOTH SIDES OF ENGINE, PASSENGER EXHAUST MANIFOLD CRACKED, EXHAUST IS LOUD WITH EXHAUST FUMES IN CAB. DEPENDING ON WHAT IS CAUSING THE FUEL SYSTEM FAILURE AND WHETHER THE CYLINDER HEADS HAVE TO BE REMOVED TO REMOVE THE BROKEN BOLTS, THESE REPAIRS COULD COST THOUSANDS.

TL* THE CONTACT OWNS A 2003 GMC SIERRA. THE CONTACT WAS DRIVING 10 MPH WHEN THE BRAKES WERE APPLIED BUT DID NOT RESPOND. THE CONTACT CONTINUED TO REPETITIOUSLY PUMP THE BRAKES UNTIL THE VEHICLE COASTED TO A STOP. THE VEHICLE WAS TOWED TO THE DEALER WHERE CORROSION WAS DISCOVERED ON THE BRAKE LINES. THE DEALER MADE REPAIRS TO THE BRAKE LINE AND ADVISED THAT THE CONTACT COULD HAVE BEEN INVOLVED IN A SEVERE CRASH IF HE WERE TO HAVE BEEN DRIVING AT HIGHWAY SPEEDS. THE FAILURE MILEAGE WAS 57,000. THE VIN WAS NOT AVAILABLE.

2003 GMC SIERRA PICK-UP I WAS DRIVING TODAY ABOUT 45 TO 50 MILES AN HOUR AND WAS RUNNING GREAT AND ABOUT AN HOUR LATER, MY SPEEDOMETER WENT UP TO 120 MILES AN HOUR AND WOULD NOT GO BACK DOWN. WHEN I GOT HOME AND PUT MY VEHICLE IN PARK, THE SPEEDOMETER WOULD ONLY GO DOWN TO 70 MILES AN HOUR. I HAVE ALMOST 68,000 MILES ON IT. WHAT IS WRONG AND WHAT CAN I DO TO GET THIS FIXED IMMEDIATELY BEFORE I GET A TICKET? *TR

TRUCK TIRE TREAD SEPARATED TWICE AND SIDEWALL BLOWOUT FROM THE INSIDE. *TR

I PURCHASED A 2003 GMC SIERRA (USED) -CHECKED IT OUT AFTER A MECHANIC TOLD ME ABOUT BRAKE LINE PROBLEMS. MY TRUCK HAS EXTREMELY BAD RUST ON THE PORTIONS OF LINE I CAN SEE (LOOKS LIKE CLAMSHELLS OPENING). I HAVE DONE SOME RESEARCH AND HAVE FOUND YOU HAVE AN OPEN INVESTIGATION ON THIS PROBLEM. I OWN 1966 AND 1980 VEHICLES WITH ORIGINAL TUBING IN BETTER CONDITION. MY QUESTION TO YOU IS SIMPLE. A RECALL WAS ISSUED FOR AFTERMARKET FUEL FILTERS THAT MAY LEAK AND CATCH ON FIRE IF YOU PARK OVER AN IGNITION SOURCE BUT NO RECALL ON A MAJOR ISSUE CONCERNING BRAKES. I AM PRETTY SURE MORE PEOPLE USE THEIR BRAKES MORE OFTEN THAN PEOPLE CHANGE FUEL FILTERS. P.S. MY NEIGHBOR HAS A 2005 DODGE THAT HAD A LINE RUPTURE-LUCKY FOR HIM HE WAS IN HIS DRIVEWAY! *TR

I HAVE 2 GM PRODUCTS, A 1996 CHEVY IMPALLA & A 2003 GMC TRUCK. BOTH HAVE THE SAME PROBLEM. AT VARIOUS TIMES AND WITHOUT NOTICE THE POWER STEERING WILL LOCK UP AND WON'T TURN FOR A BRIEF TIME. AFTER A FEW SECONDS IT WILL GO BACK TO NORMAL. ALSO IF YOU ARE STANDING STILL AND TRY TO TURN TO THE LEFT THE WHEEL IS VERY HARD TO TURN OR WON'T TURN AT ALL. FORTUNATELY THIS HAS NOT CAUSED AN ACCIDENT OR INJURY, BUT I COULD SEE A SITUATION WHERE UNDER THE WRIGHT CONDITIONS THIS COULD BE LIFE THREATENING.

TL*THE CONTACT OWNS A 2003 GMC SIERRA. WHILE THE CONTACT WAS EXAMINING HIS VEHICLE HE NOTICED THAT THERE WAS OIL DRIPPING FROM THE TRANSFER CASE UNDER THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE CONTACT WAS INFORMED THAT A COVER SHOULD BE PUT ON THE TRANSFER CASE TO STOP THE LEAKING. THE VEHICLE WAS SERVICED BY THE DEALER AND THERE WERE NO PRIOR WARNINGS. THE CURRENT AND FAILURE MILEAGES WERE 76000.

WHEN TRAVELING AT A SLOW SPEED, LESS THAN 10 MILES PER HOUR, IF BRAKE IS APPLIED THE PEDAL RUMBLES AND THE TRUCK CONTINUES TO MOVE UNLESS I PUMP THE BRAKES. THIS IS HAPPENING DURING CLEAR DAYS NO RAIN, SNOW OR LOOSE GRAVEL. THIS INCIDENT IS VERY SIMILAR TO THE ONE DESCRIBED IN CAMPAIGN NUMBER: 05V379000. *TR

DRIVING 2003 SIERRA 2500 HD 4WD CREW CAB AND ALL OF SUDDEN THE SPEEDOMETER NEEDLE QUIT STOPPED ON ZERO AND NEVER MOVED. THEN THE INSTRUMENT GAUGES OR CLUSTER COMPLETELY STOPPED WORKING. THE DEFECTIVE STEPPER MOTOR IN THE CLUSTER IS THE PROBLEM. *TR

SPEEDOMETER FAILS TO WORK. IT OCCURS CONTINUOUSLY. NOTHING HAS BEEN DONE TO FIX THE PROBLEM. *TR

TL*THE CONTACT OWNS A 2003 GMC SIERRA. WHILE DRIVING LESS THAN 10 MPH IN A BUSY PARKING LOT, THE CONTACT DEPRESSED THE BRAKE PEDAL BEFORE COMPLETING A LEFT TURN AND FELT THE BRAKES SHAKING. THE BRAKE PEDAL EXTENDED TO THE FLOOR. HE WAS ABLE TO MANEUVER THE VEHICLE TO SAFETY AND CONTINUED TO APPLY THE BRAKES. HE ALLOWED THE VEHICLE TO COAST UNTIL IT CAME TO A COMPLETE STOP. THE DEALER STATED THAT THE FAILURE OCCURRED DUE TO CORROSION OF THE BRAKE LINES. THE MANUFACTURER WOULD NOT ASSIST WITH THE REPAIRS DUE TO THE CORROSION. THE FAILURE AND CURRENT MILEAGES WERE 87,974. UPDATED 12/17/08. *LJ THE REAR MAIN SEAL WAS LEAKING OIL. THE WHEEL SPEED SENSOR WAS REPLACED, DUE TO THE ABS LIGHT ILLUMINATING. UPDATED 12/18/08. *JB

SUMMER 2007 WE RECEIVED A NOTICE FROM GMC FOR OUR 2003 GMC SIERRA THAT STATED "YOUR VEHICLE COULD DEVELOP A CONDITION WHERE ONE OR MORE OF THE INSTRUMENT PANEL GAUGE NEEDLES MAY STICK, FLUTTER, OR BECOME INOPERATIVE. THIS MAY CAUSE INACCURATE READINGS, INCLUDING THE SPEEDOMETER AND THE FUEL GAUGE." THEY OFFER TO CORRECT THIS PROBLEM IF IT OCCURS IN VEHICLES WITHIN 7 YEARS OR 70,000 MILES, WHICHEVER IS LESS. OUR GMC SIERRA DEVELOPED THIS CONDITION RECENTLY AT 5 YEARS AND 90,000. THE SPEEDOMETER BEGAN TO DISPLAY INACCURATE SPEEDS AND EVENTUALLY STARTED ERRATICALLY PULSING AND SOMETIMES DISPLAYING NO SPEED. THIS IS VERY UNSAFE TO HAVE THIS HAPPEN WHEN YOU ARE DRIVING. THERE ARE NUMEROUS ENTRIES ONLINE INDICATING THAT THIS HAS HAPPENED TO MANY OF THE VEHICLES IN THE 5 YEAR RANGE, MANY JUST AFTER THE MILEAGE CUT OFF. DISPLAYING PROPER SPEED IS IMPORTANT TO SAFETY AND IF THEIR INSTRUMENT PANELS ARE FAILING ON MULTIPLE VEHICLES THE MANUFACTURER SHOULD BE RESPONSIBLE FOR REPLACING THEM REGARDLESS OF AGE OR MILEAGE. *TR

INSTRUMENT CLUSTER INOPERATIVE. 2003 GMC SIERRA PICK UP. RECEIVED A LETTER FROM GM AND DUE TO THE MILEAGE THEY WILL NOT REPAIR THE CLUSTER EVEN THOUGH THE VEHICLE IS WITHIN THE DATE RANGE. THE MILEAGE LISTED IS NOT REASONABLE SINCE THEY ONLY ALLOW 10K PER YEAR. THEY WERE CALLED WHEN I RECEIVED THE LETTER AT 104K AND NOW AT 111K THEY CAN ONLY APOLOGIZE FOR THE PROBLEM BUT NOT FIX IT UNDER WARRANTY. I FEEL IT IS A SAFETY ISSUE BUT THEY DO NOT. SO I AM HAVING IT FIXED FOR ALMOST 600 DOLLARS WITH NO HELP FROM GM. THIS SHOULD BE A RECALL SINCE THEY KNEW OF THE PROBLEM AND IT HAS OCCURRED ENOUGH TO WARRANT SENDING OUT LETTERS NOTIFYING THE OWNERS OF A POTENTIAL PROBLEM. *TR

THE STEERING COLUMN MAKES A POPPING SOUND AS IF SOMETHING IS LOOSE IN IT. THE PROBLEM WAS SUPPOSEDLY FIXED WHILE THE VEHICLE WAS UNDER WARRANTY. AFTER WARRANTY RAN OUT THE PROBLEM CAME BACK. I WAS THEN CHARGED $60 TO GET THE STEERING COLUMN GREASED. THIS WORKED TEMPORARILY AS BEFORE. *TR

1. STARTED VEHICLE AND SPEEDOMETER INDICATED 50 MPH. SPEEDOMETER INCREASED AS SPEED INCREASED AND DECREASED AS SPEED DECREASED. WHEN VEHICLE IS TURNED OFF SPEEDOMETER INDICATES 50 MPH. 2. UNABLE TO CORRECTLY DETERMINE TRUE SPEED OF VEHICLE. 3. NONE. *TR

SPEEDOMETER FAILURE WHILE DRIVING.. HAD NO IDEA HOW FAST I WAS GOING, ENDED UP GETTING A SPEEDING TICKET AND HAD TO GET IT REPAIRED PER POLICE OFFICER. *TR

TL*THE CONTACT OWNS A 2003 GMC SIERRA. THE CONTACT STATED THAT THE SPEEDOMETER FAILED AT VARIOUS SPEEDS. WHILE IDLING AT A STOP SIGN, THE SPEEDOMETER WOULD DISPLAY 160 MPH. WHILE DRIVING, THE SPEEDOMETER WOULD REMAIN AT ZERO. THE FAILURE BEGAN ON SEPTEMBER 27, 2007 AND HAS BEEN OCCURRING INTERMITTENTLY. THE VEHICLE WAS TAKEN IN FOR REPAIR ON OCTOBER 1, 2007. THE CURRENT AND FAILURE MILEAGES WERE 11,108.

TL*THE CONTACT OWNS A 2003 GMC SIERRA. THE CONTACT STATED THAT THE VEHICLE SPEED CONTROL NEEDLE STOPPED WORKING AND IT IS CURRENTLY STUCK AT 120 MPH. WHILE DRIVING 30 MPH, THE VEHICLE SPEED CONTROL DISPLAYED 80 MPH. THE VEHICLE WAS TAKEN TO THE DEALER FOR REPAIR AND THEY STATED THAT IT WOULD COST $600, IN WHICH HE WOULD BE RESPONSIBLE FOR PAYING. THE GM MANUFACTURER ALSO STATED THAT HE WOULD BE LIABLE FOR THE SPEED CONTROL REPAIR. THE CURRENT AND FAILURE MILEAGES WERE 44,550.

DAY TIME RUNNING LIGHT BURNED OUT. WHEN I REPLACED IT THE BOTTOM OF THE BULB WAS BURNED AND THE PLASTIC WIRING SOCKET WAS PARTIALLY MELTED AND BRITTLE AROUND THE BULB BASE. I CHANGED THE BULB AND THE LIGHT STILL WORKS. HOWEVER, I ALSO HAD TROUBLE WITH ONE OF MY TWO HORNS NOT WORKING, BUT AFTER REPLACING THE BURNED OUT BULB, BOTH HORNS WORKED. WIRING SEEMS TO BE IN SERIES WITH HORN(S) AND BURNED OUT BULB DISABLES HORN. *JB

TL*THE CONTACT OWNS A 2003 GMC SIERRA. WHILE DRIVING APPROXIMATELY 65 MPH UNDER ANY CONDITIONS, THE VEHICLE'S ODOMETER FAILS. THE FAILURE OCCURS WHEN THE VEHICLE STOPS AND STARTS. THE CONTACT WOULD HAVE TO SHUT THE VEHICLE OFF AND RESTART IT IN ORDER TO MAKE THE SPEEDOMETER WORK PROPERLY. THE FAILURE OCCURS INTERMITTENTLY. THE DEALER STATED THAT THE INSTRUMENT PANEL NEEDED TO BE REPLACED. THE CURRENT AND FAILURE MILEAGES WERE 27,051. THE SPEEDOMETER WOULD NOT FUNCTION AFTER DRIVING 45 MINUTES WHEN ON CRUISE CONTROL. UPDATED 06/13/07. *JB

ABS BRAKE SYSTEM ACTIVATES DURING LOW SPEED STOPPING ON DRY PAVEMENT. *TR

4 WHEEL DRIVE TRANSMISSION WILL SHIFT FROM 2 WHEEL TO 4 WHEEL LOW WHILE DRIVING. SOMETIMES IT WILL SHIFT TO NEUTRAL. THIS CAN BE VERY DANGEROUS. YOU BASICALLY DON'T HAVE THE CONTROL OF THE VEHICLE THAT YOU THOUGHT YOU HAD. *JB

AFTER SITTING IN STOP-AND-GO TRAFFIC I NOTICED THAT THE SPEEDOMETER WAS READING AT 100 MPH AND I WAS AT A STOP LIGHT. AT THE TIME, I HAD LESS THAN 50,000 MILES ON MY TRUCK. SINCE THEN THE SPEEDOMETER WAS ALMOST ALWAYS INCORRECT. IT HAS OCCASIONALLY FIXED" ITSELF, BUT USUALLY DID NOT LAST MORE THAN A DAY OR TWO. THE NEEDLE WAS OFTEN BURIED PAST 120 MPH. A NUMBER OF MY FRIENDS AND RELATIVES WITH SIMILAR VEHICLES HAD THE SAME PROBLEM. CURRENTLY I HAVE NOT PAID TO HAVE THE PROBLEM FIXED, BUT HOPE THAT IT WILL BE RECALLED AT SOME POINT SOON.*AK

I OWN A 2003 GMC SIERRA WITH 39,543 MILES AS OF 3/5/07. A COUPLE OF MONTHS AGO THE SPEEDOMETER BEGAN READING ERRATICALLY AND HAS NOW COMPLETELY QUIT WORKING. IN DOING SOME RESEARCH ON THE INTERNET I SEE I'M NOT THE ONLY PERSON THAT IS HAVING THIS PROBLEM. *JB

SPEEDOMETER FAILURE. REPLACED AT A COST OD APPROXIMATELY $450.00. FAILURE ON MY OTHER TRUCK. GMC 2500HD 4X4 IN 2006. *JB

THE TRANSMISSION CLUNKS WHEN SHIFTING FROM 2ND - 3 RD AND AT TIMES THE ENGINE WILL REV AND FINALLY IT WILL TAKE OFF, THIS HAS CAUSED AN ISSUE WHEN GOING THROUGH AN INTERSECTION. THE DEALERSHIP ATTEMPTED FOUR REPAIRS AND IT IS NOT FIXED. THE ISSUE STARTED WHEN THE VEHICLE HAD 6K MILES ON IT AND IT IS GETTING WORSE. THE SPEEDOMETER IS SPORADIC IN THAT IT WILL SHOW SPEED REDUCTION/INCREASE IN SEGMENTS - AS IF IT WERE STICKING. THE ERRONEOUS SPEED INDICATION CAUSES AN ISSUE WHEN GOING TOO SLOW OR TOO FAST IN TRAFFIC. *NM

TRAVELING 47 MPH OR HIGH, WIPER BLADE LIFTS OFF WINDSHIELD AND DOES NOT COME INTO CONTACT TO CLEAN WINDSHIELD. *JB

THE SPEEDOMETER ON MANY OF THE 01-06 MODEL GMC/CHEV TRUCKS INCLUDING MY 2003 GMC SIERRA WILL GO OUT. THE FAILURE STARTS WITH THE SPEEDOMETER STICKING 20-30 MPH HIGH AND WILL FUNCTION CORRECTLY WITH THAT DELTA. EVENTUALLY THIS DELTA WILL GROW AND CAN ONLY BE REDUCED BY STARTING THE ENGINE REPEATEDLY. THE SPEED WILL GO DOWN BY A CONSTANT 5 MPH EACH TIME YOU RESTART BUT THIS WILL EVENTUALLY LEAD TO BURNING A STARTER. THIS ALSO LEAVES THE DRIVER TO GUESS WHAT THE CORRECT DELTA IS. THIS MORNING THE SPEEDOMETER CONTINUED TO CLIMB EVEN THOUGH I WAS GOING A CONSTANT 30 MPH ON A CITY STREET. I KNOW THIS BECAUSE I WAS SPOKE A FRIEND THAT IS A COUNTY SHERIFF THAT WAS CLOCKING TRAFFIC AT THE TIME. THE SPEEDOMETER CONTINUED TO CLIMB UP TO THE LIMIT SPEED OF 120 MPH WHILE I WAS STILL GOING 30 MPH. THE SPEEDOMETER EVENTUALLY PASSED 120 MPH AND RESTED AT 245 DEGREES FROM THE 0 POSITION. THIS LEFT ME WITH ZERO SPEED INDICATION WHETHER IT BE A DELTA OR TRUE. THIS WAS A SIGNIFICANT SAFETY EVENT AND I DIDN'T FEEL VERY SAFE DRIVING THE VEHICLE THIS WAY. AFTER I ARRIVED AT WORK I BEGAN SEARCHING THE WEB TO FIND A SOLUTION, AND THAT I DID. I HAVE FOUND HUNDREDS OF PEOPLE THAT HAVE HAD THE SAME PROBLEM IN MANY GMC/CHEVROLET TRUCKS. HTTP://WWW.TOPIX.NET/FORUM/AUTOS/CHEVROLET-TAHOE/T2BGKBGI55EKNU77C/P5 THIS WIDESPREAD PROBLEM MUST BE REVIEWED AND IN MY OPINION (I AM A MECHANICAL ENGINEER FOR A LARGE MANUFACTURER) THIS SHOULD BE FIXED BY THE COMPANY AT FAULT WHICH IS GM. THIS VEHICLE WILL BE PARKED ONC

SPEEDOMETER ON 2003 GMC SIERRA FAILS CONSTANTLY AND WHEN IT WORKS, IT WORKS ERRATICALLY THE HEAT GAUGE, AND BATTERY GAUGE WORK PART OF THE TIME OR ERRATICALLY OR DO NOT WORK AT ALL. I'VE READ MESSAGE BOARDS OF OTHERS THAT HAVE COMPLAINED OF THE SAME PROBLEM ON 2003 GMC. *JB
