2003 GMC Sierra Complaint Log

UNKNOWN

HAD INJECTORS REPLACED UNDER WARRANTY AT 50000 MILES AFTER NOTICING EXCESS EXHAUST SMOKE ON STARTUP AND ALSO POWER STEERING HOSES WERE LEAKING, AGAIN AT 105000 MILES THEY TOTALLY FAILED AS I WAS BRINGING MY WIFE HOME FROM HOSPITAL ON I-15 IN CA. UP CAJON PASS AND HAD TO BE TOWED TO DEALER, BUT GM DEALER WOULD NOT COVER INJECTORS UNDER WARRANTY AS TRUCK WAS11 YEARS OLD AND THEIR COVERAGE WAS FOR 7 YEARS ONLY, NOW AGAIN HAD TO HAVE THEM REPLACED AT 147000 MILES BECAUSE OF EXCESSIVE SMOKE ON STARTUP. THIS TIME I WENT TO AN INDEPENDENT SHOP AS THEY WERE $1000 CHEAPER AND STATED THESE UPGRADED INJECTORS SHOULD LAST 150000 MILES NOT 50000. HAD TO HAVE POWER STEERING HOSES REPLACED AGAIN ALSO ALONG WITH POWER BRAKE SERVO BECAUSE THEY WERE LEAKING AGAIN AT 157000 MILES. I HAVE ALL OF THIS DOCUMENTED IN WRITING BY SERVICE DEPTS.

HYDRAULIC BRAKE LINES CORRODED CAUSING LEAKS AND BRAKE FAILURE

BLOWER MOTOR RESISTOR DOES NOT OPERATE. UPON INSPECTION, HARNESS AND FINAL STAGE ARE DAMAGED DUE TO EXCESSIVE HEAT. I NEED TO REPLACE BOTH COMPONENTS BECAUSE I FEAR IT WILL CAUSE A FIRE. MANY POSTS ON THE SAME THING. WHY IS THERE NOTHING DONE ABOUT THIS? MY BMW HAD SAME ISSUE BUT IT WAS A RECALL ON THEIR CARS. WHY IS IT NOT A RECALL ON GM? IS IT BECAUSE THEY ARE AN AMERICAN CAR COMPANY?

THE HORN QUITS WORKING AND THIS CREATES A HUGE SAFETY ISSUE. ONLINE SEARCH SHOWS THIS IS A COMMON PROBLEM AND THE DEALER IS UNABLE TO FIX IT.

76000 MILES; ISSUE ONGOING BEGINNING IN NOVEMBER 2018 ON DRY PAVEMENT AT LOW SPEED (UNDER 10 MPH) BRAKING IS COMPROMISED BY ABS SYSTEM ENGAGEMENT ISSUE. BELOW 10 MPH, THE ABS SYSTEM ENGAGES CAUSING DRY PAVEMENT BRAKING TO BE DOUBLE OR TRIPLE THE NORMAL DISTANCE TO STOP PRIOR TO THE ABS ISSUE. THIS IS A SAFETY ISSUE SINCE ABS SYSTEM PULSING OF THE BRAKES AT SLOW SPEEDS ON DRY PAVEMENT IS UNEXPECTED. AT A STOP SIGN/CROSSWALK, THIS HAS CAUSED A VERY CLOSE ENCOUNTER. VEHICLE HAS LESS THAN 80000 MILES AND HAS BEEN SERVICED ROUTINELY BY A CERTIFIED MECHANIC. REPLACEMENT/SERVICE OF ABS SPEED SENSORS AND RUST ISSUE DID NOT CORRECT THE PROBLEM. I HAVE NEVER BEEN CONTACTED REGARDING THE RECALL THAT EXISTS FOR THIS ISSUE. REQUIRE ASSISTANCE TO DETERMINE WHY A VEHICLE WITH THIS MILEAGE HAS THIS OBVIOUS SAFETY ISSUE AND GM HAS PROVIDED NO RELIEF.

WHILE DRIVING APPROXIMATELY 35 MPH IN TOWN, THE VEHICLE IN FRONT OF ME SIGNALED TO MAKE A LEFT HAND TURN. I BEGAN TO SLOW DOWN THE VEHICLE AND THEN I LOST ALL BRAKE PRESSURE. I WAS UNABLE TO STOP THE TRUCK TO AVOID AN ACCIDENT DUE TO COMPLETE BRAKE FAILURE! THERE WERE NO PREVIOUS LIGHTS OR WARNING SIGNALS NOTIFYING OF A BRAKE PROBLEM PRIOR TO THIS. THE WARNING LIGHT CAME ON AFTER THE ACCIDENT. THE BRAKE FLUID RESERVOIR WAS FULL. AFTER FURTHER INVESTIGATION, IT APPEARS THAT THE BRAKE LINES WERE CORRODED CAUSING THE BRAKE FAILURE.

TL* THE CONTACT OWNS A 2003 GMC SIERRA 1500. WHILE DRIVING APPROXIMATELY 15 MPH IN A PARKING LOT, THE CONTACT SLAMMED ON THE BRAKE PEDAL TO AVOID ANOTHER VEHICLE THAT ABRUPTLY PULLED IN FRONT OF HIS VEHICLE. THE BRAKE PEDAL TRAVELED TO THE FLOOR WITHOUT STOPPING THE VEHICLE IMMEDIATELY. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE DEALER WAS NOT CALLED; HOWEVER, THE CONTACT SPOKE TO A TECHNICIAN WHO STATED THAT HE COULD REPAIR THE FAILURE BY CUTTING OUT THE ROTTED SECTION OF THE BRAKE LINE AND REPLACING IT WITH A NEW SECTION. THE FAILURE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND DID NOT ASSIST. THE FAILURE MILEAGE WAS 127,600. THE VIN WAS NOT AVAILABLE.

LOSS OF BRAKES DUE TO RUSTED THROUGH BRAKE LINES. WHILE PULLING A TRAILER WITH PONTOON BOAT, ALL OF A SUDDEN WHEN STOPPING I SUDDENLY HAD NO BRAKES. JUST CAME OFF THE FREEWAY BUT WAS GOING SLOW WHEN THE FAILURE OCCURRED. NEED TO REPLACE NOW. ALSO, RUSTED THROUGH POWER STEERING LINES. ALREADY REPLACED. ALSO, RUSTED TRANS COOLER LINES. WILL NEED TO REPLACE SOON.

COMPLAINT INVOLVES REDUCED POWER MODE WHILE DRIVING. THIS HAS BECOME A SAFETY CONCERN BECAUSE OF THE RAPID DROP IN SPEED WHILE DRIVING. IT IS UNSAFE TRYING TO EXIT TRAFFIC LANES WITH NO RESPONSE FROM THROTTLE PEDAL AND APPEARS TO BE A COMMON PROBLEM WITH DRIVE BY WIRE VEHICLES PRODUCED BY GENERAL MOTORS. VEHICLE HAS BEEN TO DEALERSHIP TWICE WITH NO RESOLUTION OF THE PROBLEM. THIS FAILURE HAS OCCURRED AT VARIOUS SPEEDS, TIMES OF DAY, TEMPERATURES ETC. IT WILL ENTER REDUCED POWER ONCE TO TWICE A DAY. THANK YOU FOR YOUR TIME.

BRAKE FAILURE UPON SLOWING DOWN AT OFF RAMP. AVOIDED ACCIDENT BUT HAD TOTAL BRAKE FAILURE. PULLED INTO PARKING LOT, CHECKED FLUID LEVELS, WERE OK, TRIED BRAKES AGAIN AND THEY WERE WORKING. HAVE NOT HAD A PROBLEM SINCE.HAVE HEARD REPORTS OF SIMILAR NATURE. SOME THINK IT IS A PROBLEM IN THE VALVING.HOPE YOU CAN FIND A CURE.

An accident has not occurred yet, but it something I'm concerned deeply about. Awhile back there was a recall on the instrument cluster of the gmc Sierra 1500 (possibly othets on the list, im sure). I did wind up having the cluster replaced, there didn't seem to be any issues at the time. Now...the replacement cluster has gone haywire. I notice no issues with operations at this time. But the cluster doesn't register certain things or it fluctuates on and off, or doesn't read correctly at all. Is it possible that the replacement could have been bad as well?

TL* THE CONTACT OWNS A 2003 GMC SIERRA 1500. THE CONTACT OBSERVED AN ABNORMAL SOUND FROM THE REAR BRAKES WITHOUT WARNING. THE CONTACT TOOK THE VEHICLE TO THE LOCAL DEALER (BETTEN BAKER GMC LOCATED AT 749 W MAIN ST, LOWELL, MI, 49331) WHERE IT WAS DIAGNOSED THAT THE REAR BRAKES HAD FAILED. THE VEHICLE WAS REPAIRED. TWO WEEKS LATER, THE CONTACT OBSERVED A PUDDLE UNDER THE FRONT DRIVER DOOR AND REALIZED IT WAS BRAKE FLUID. IN ADDITION, THE CONTACT OBSERVED THAT THE PAINT ON THE FRAME WAS FAILING AND WAS WET DUE TO THE EXCESSIVE LEAKAGE OF THE BRAKE FLUID. THE CONTACT RESEARCHED ONLINE TO SEE THE COMPLAINTS ON HIS VEHICLE AND FOUND A CLOSED INVESTIGATION DUE TO BRAKE LINE CORROSION UNDER NHTSA ACTION NUMBER: EA11001 (BRAKES). THE VEHICLE WAS NOT DIAGNOSED AGAIN. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 117,000.

MY TRUCK HADN'T BEEN DRIVEN FOR A COUPLE OF WEEKS, BUT THERE WAS NO INDICATION OF ANYTHING AMISS THE LAST TIME I DROVE IT. THE TRUCK IS PARKED AT THE TOP OF A APPROX. 40FT. LONG DRIVEWAY THAT IS MODERATELY STEEP. I STARTED THE TRUCK AND SLOWLY BEGAN BACKING DOWN THE DRIVEWAY AND THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR. IT FLEW DOWN THE DRIVEWAY, GOING BETWEEN A PARKED CAR AND ANOTHER STEEP HILL, WINDING UP IN MY NEIGHBORS FRONT YARD, WHERE I MANAGED TO ABRUPTLY TURN IT AND BRING IT TO A STOP BEFORE GOING THRU HIS LIVING ROOM. FREQUENTLY, THERE ARE AS MANY AS 6TO8 KIDS PLAYING THERE, BUT BEING A BAD WEATHER DAY(COLD),, LUCKILY, THERE WAS NOBODY THERE. THE POSSIBILITIES OF A TERRIBLE DISASTER ARE FRIGHTENING. AS IT STANDS, THE ONLY 'DISASTERS' ARE THE RUTS IN MY NEIGHBORS YARD, A DESTROYED RECYCLING CONTAINER AND MY BANK ACCOUNT,-TO A TUNE OF JUST OVER 1700$. MY MECHANIC SAYS HE HAS DONE OVER A HALF DOZEN OF THESE REPAIRS LATELY. TO MY WAY OF THINKING, GM IS SERIOUSLY NEGLIGENT REGARDING THIS PROBLEM, WHICH I HAVE DISCOVERED IS FAIRLY COMMON. ARE THEY WAITING TO SEE HOW MANY HORRIFIC EVENTS OCCUR BEFORE ADDRESSING THIS? AT THE VERY LEAST, THEY SHOULD GIVE REIMBURSEMENT TO THOSE OF US THAT HAVE GONE THRU THIS. AND WHERE IS NHTSA'S ACTION ON THIS ISSUE??? *TR

I HAVE A 2003 GMC SIERRA 1500. WHEN TURNING AT LOW SPEED AT TIMES THE POWER STEERING GOES OUT FOR A FEW SECONDS THEN COMES BACK. YESTERDAY I ALMOST HIT A CAR HEAD ON DUE TO THIS PROBLEM. I WAS TURNING INTO A GAS STATION AND THE STEERING WENT OUT. A CAR WAS PULLING OUT OF THE STATION AS I WAS PULLING IN AND THE POWER STEERING WENT OUT. I WAS GOING STRAIGHT AT AND I STRUGGLED THROUGH IT TO MAKE THE TRUCK TURN. IF MY WIFE WOULD HAVE BEEN DRIVING THE TRUCK, THERE WOULD HAVE BEEN AN ACCIDENT. THIS NEEDS TO BE RECALLED AND FIXED BEFORE SOMEONE GETS KILLED. THIS HAS BEEN GOING ON FOR THE LAST 6 MONTHS BUT YESTERDAY WAS A CLOSE CALL. *TR

STARTED MY VEHICLE APPLIED THE BRAKE TO SHIFT TO DRIVE AND THE BRAKE PEDAL WENT TO THE FLOOR. I GOT OUT OF THE VEHICLE AND THERE WAS A PUDDLE OF BRAKE FLUID ON THE GROUND ON THE DRIVER SIDE UNDER WHERE THE DRIVERS SEAT IS. THERE WAS BRAKE FLUID DRIPPING FROM A RUSTED BRAKE LINE. I'M LUCKY THIS HAPPENED WHEN THE VEHICLE WAS STOPPED AND NOT WHILE I NEEDED STOP BECAUSE IT WAS A COMPLETE LOSS OF BRAKES.

I WAS DRIVING ON I 75 DOING 70 MPH I HAD TO COME TO A SUDDEN STOP I APPLIED BRAKES AND THERE WAS NO BRAKES., I ENDED UP PUTTING TRUCK IN THE DITCH TO AVOID SERIOUS ACCIDENT. IT ENDED BOTH BRAKE LINES FROM MASTER CYLINDER BOTH BLEW UP FROM CORROSION THESE LINES WENT TO THE ABS MODULE. I WAS SOME WHAT INJURED. *TR

ABS COMES ON AT LOW SPEED.. IT INCREASES STOPPING DISTANCE.. I HAVE ONCE REAR ENDED A VEHICLE BECAUSE OF THIS. THERE WAS NO DAMAGE TO EITHER VEHICLE.. ALSO MY ABS LIGHT COME ON FOR A FEW SECONDS MAYBE TWO OR THREE TIMES A MONTH..

BRAKES FAILED WHILE ON BOAT RAMP CAUSING BOAT TO KNOCK ME DOWN UNDER TRAILER AS I WAS PULLING DRAIN PLUG .DRIVER WAS ABLE TO APPLY PARKING BRAKE AND PUTTING TRUCK IN DRIVE . BRAKE LINES FAILED BRAKE PETAL WHEN TO FLOOR RUSTED LINES . THEN FOUND OUT THAT IS VERY COMMON WITH GM TRUCKS IN THIS YEAR . RESULT I AM PISSED , A NOTICE FROM GM WOULD HAVE BEEN NICE . WHAT WOULD HAPPEN IF I HAD TO STOP AT A INTERSECTION OR ON THE INTERSTATE.

BRAKE LINE FAILED, NO BRAKES WHILE HEADING FOR A RED LIGHT. DRIVE OFF ROAD TILL VEHICLE STOPPED. BRAKE LINE FROM MASTER CYLINDER TO ABS CONTROL , ROTTED OUT. UPON FURTHER INSPECTION, ALL BRAKE LINES ARE ROTTED OUT. MY MECHANIC STATES THEY ALL NEED TO BE REPLACED, IT WILL HAPPEN AGAIN.

SEVERELY RUSTED BRAKE LINES THAT SPLIT. MAIN LINE FROM MASTER CYLINDER TO ABS MODULE AND REAR LINE JUST INBOARD OF LH REAR TIRE. PEDAL WENT TO THE FLOOR ON CITY STREET WHEN DRIVING.

THE ABS ACTIVATES AT LOW SPEED BRAKING UNDER DRY ROAD CONDITIONS WITHOUT THE TIRES LOCKING UP. THE BRAKE PEDAL VIBRATES AS IF I WERE ON ICE WITH THE TIRES LOCKED UP. BRAKING EFFECT IS REDUCED UNDER THESE CONDITIONS. THIS HAPPENS RANDOMLY AND WHEN IT DOES I CANNOT BE SURE IF I CAN STOP IN TIME BEFORE HITTING THE VEHICLE OR OBJECT IN FRONT OF ME.

82K MILES, ORIGINAL OWNER, WELL MAINTAINED AND GARAGED. HAD TO STOP AT A RED LIGHT AND THE PEDAL WENT TO THE FLOOR AS I WENT INTO THE INTERSECTION.LUCKILY NO OTHER CARS WERE AHEAD OF ME AND NOBODY WAS HURT. DIC LIGHTS CAME ON AND BRAKES HAVE NOT WORKED SINCE LIMPING MY VEHICLE BACK HOME.

BRAKE LINE FAILURE COMPLETE LOSS OF BRAKES WHILE DRIVING ON HWY OFF RAMP.

PULLING TO A STOP IN MY DRIVEWAY MY BRAKES SLOWED THE TRUCK AND THEN COMPLETELY GAVE WAY WITH THE PEDAL HITTING THE FLOOR. I STOMPED ON THE EMERGENCY BRAKE PEDAL TO KEEP FROM HITTING THE PORCH. I AM SO LUCKY TO HAVE THAT HAPPEN AT LOW SPEED OFF THE ROAD. THAT COULD HAVE BEEN A TRAGEDY ON THE HIGHWAY. TURNS OUT THAT MY BRAKE LINES ARE SEVERELY RUSTED AND ONE OF THE 2 LINES COMING OFF THE MASTER CYLINDER NOW HAS A PINHOLE LEAK IMMEDIATELY ABOVE THE FRAME WHERE IT BENDS 90 DEGREES TO GO BACK TO THE ABS MANIFOLD. APPLYING THE BRAKES JUST SQUIRTS FLUID OUT OF THE LINE. I THOUGHT A SINGLE FAILURE WAS SUPPOSED TO RESULT IN REDUCED BRAKING POWER, NOT COMPLETE LOSS OF BRAKES. NOTE THAT MY TRUCK IS IN OTHERWISE GREAT SHAPE AND I SIMPLY HAD NO IDEA. IT IS CLEAR THAT THE NHTSA HAS BEEN BAMBOOZLED BY GM. BRAKE LINES ARE A CRITICAL LIFE SAFETY SYSTEM, INSTALLED ON AND IN SOME PLACES IN THE CHASSIS BEFORE THE VEHICLE BODY AND BED ARE ATTACHED. IT IS NOT ROUTINE MAINTENANCE TO RINSE THE BRAKE LINES LET ALONE REPLACE THEM. GM PUSHING THIS BACK ON THE CUSTOMER IS COMPLETE BS. YOU CAN BUY NYLON COATED OR STAINLESS STEEL BRAKE LINES FOR LESS THAN 100 $. THE INCREMENTAL COST TO GO FROM STEEL TO SOMETHING THAT WOULD LAST THE OPERATIONAL LIFE OF THE VEHICLE IS LESS THAN 50 $. I'M WAITING ON AN ESTIMATE FROM MY NON-DEALER SHOP, BUT A DEALER CHARGING 3600 $ IS NOT SURPRISING CONSIDERING THE AMOUNT OF LABOR THAT MUST BE INVOLVED. THE NHTSA DECISION ON THE ISSUE IS UNCONSCIONABLE. GUESS IT MIGHT HAVE BEEN DIFFERENT IF THEY HAD RUN OVER A CHILD AT A CROSSWALK OR IF THEIR CHILD WAS MOWED DOWN BY CORPORATE GREED. HOPEFULLY THAT NEVER HAPPENS, BUT WITH SO MANY ROTTING GM TRUCKS ON THE ROAD, WE WILL HAVE TO KEEP OUR FINGERS CROSSED.

I WAS ON MY WAY HOME RUNNING 45 MPH IN LIGHT TRAFFIC. WHEN I WENT TO MAKE A LEFT HAND TURN AND MY BRAKE PEDAL WENT TO THE FLOOR. SCARED THE HELL OUT OF ME. I WAS ABLE TO PUMP THEM ENOUGH TO MAKE THE TURN AND LUCKILY I WAS ONLY THREE BLOCKS FROM MY HOME. I WAS ABLE TO COAST IT HOME. I RAISED THE HOOD AND ALL THE BRAKE LINES ARE SO RUSTY. I HAD MY WIFE STEP ON THE BRAKE AND YOU CAN SEE ONE LINE BUSTED. I CHECKED WITH DEALER AND THEY DON'T OFFER REPLACEMENT PARTS. YOU HAVE PAY SOMEONE TO MAKE THE LINES FOR YOU.

TURNING INTO AN AUTO PARTS STORE, FROM THE HIGHWAY, WHEN I APPLIED THE BRAKES THE PEDAL WENT CLEAR TO THE FLOOR. MY TRUCK SLOWED BUT NOT ENOUGH IF ANYONE WALKING OR A CAR HAD BEEN THERE I WOULD HAVE HIT THEM. I WAS VERY LUCKY. OF THE FOUR BRAKE LINES ONE BURST, TWO WERE SEEPING, BUT NOT DRIPPING AND THE REAR LINE WAS ALMOST AS BAD AS THE OTHER LINES AND ITS A WONDER IT DIDN'T BREAK AT THE SAME TIME. GOING HOME I WOULD HAVE GONE DOWN A VERY STEEP HILL WITH A STOPLIGHT AND A VERY BUSY INTERSECTION. IT COULD HAVE BEEN A DISASTER. THIS IS A LOW MILEAGE TRUCK, SELDOM DRIVEN IN SNOW.

I WAS DRIVING HOME FROM WORK ON I-75 AND STARTED DETECTING A STRONG SMELL OF GASOLINE. I PULLED OVER AND INSPECTED THE VEHICLE. I FOUND THAT THE FUEL LINE HAD RUSTED AND WAS SPRAYING GAS EVERYWHERE. UPON FURTHER INSPECTION, I FOUND THAT ALL THE LINES FOR THE FUEL AND BRAKE SYSTEM WERE SEVERELY RUSTED AND WILL NEED TO BE REPLACED TO AVOID CATASTROPHIC FAILURE THAT COULD RESULT IN SERIOUS INJURIES TO MYSELF AND OTHERS ON THE HIGHWAY. I HAVE RESEARCHED AND FOUND THAT THERE HAVE BEEN THOUSANDS OF COMPLAINTS FILED, BUT NO ACTION TAKEN. AS AN ADDED NOTE...I BOUGHT THE TRUCK NEW, IT IS KEPT IN THE GARAGE MOST OF THE TIME, AND I DO NOT LIVE IN A STATE THAT IS KNOWN FOR HEAVY SNOW FALL OR SALT USAGE. I ALSO HAVE A 1965 MODEL CAR THAT HAS NEVER HAD THE FUEL LINES OR BRAKE LINES REPLACED.

EXITING OFF FREEWAY RAMP IN INDIANAPOLIS BRAKE PEDAL WENT TO THE FLOOR WITHOUT NOTICE AND NO BRAKE FLUID LOSS, NEARLY CRASHED CROSSING 5 LANES OF CROSS TRAFFIC JUST LUCKY I WASN'T BROADSIDED BY CROSS TRAFFIC. I RECEIVED NO NOTICE OF HAZARD FROM GM, NO RECALL AND ONLY LEARNED OF THIS PROBLEM ONCE RESEARCHING ON WEB. I AM LUCKY TO BE ALIVE.

I WAS TOWING MY 33' TRAVEL TRAILER WITH MY VERY WELL MAINTAINED 2003 GMC SIERRA 1500 PICK UP TRUCK. AFTER A FOUR AND A HALF HOUR TRIP ON THE INTERSTATE HIGHWAY DOING 65 MPH, I ARRIVED AT MY CAMPGROUND. AS I WAS BACKING MY TRAILER INTO MY CAMP SITE, MY BRAKE PEDAL WENT TO THE FLOOR AND MY DASHBOARD LIT UP WITH WARNING LIGHTS. I HAD COMPLETE BRAKE FAILURE. I PUT THE TRUCK IN PARK AND GOT OUT TO LOOK UNDER THE TRUCK. RIGHT BELOW THE DRIVER SEAT, BRAKE FLUID WAS POURING OUT OF THE BRAKE LINE WHICH HAD BURST OPEN. I HAD NO BRAKES. THANK GOD THIS HAPPENED WHILE I WAS BACKING THE TRAILER IN AT 2 MPH. MINUTES PRIOR TO THIS I WAS GOING 65 MPH ON THE HIGHWAY, TOWING A 33' TRAILER. I SHUTTER TO THINK WHAT COULD HAVE HAPPENED IF THIS LINE BURST WHILE AT HIGHWAY SPEEDS. MY WIFE AND I WERE FREAKED OUT FOR DAYS THINKING ABOUT WHAT COULD HAVE HAPPENED. WE HAD TO HAVE THE TRUCK TOWED TO A REPAIR SHOP AND ENDURE A VERY EXPENSIVE REPLACEMENT OF ALL THE BRAKE LINES, WHICH WERE COMPLETELY CORRODED. WHILE THE TRUCK WAS BEING FIXED I DID SOME RESEARCH ON THIS PROBLEM AND FOUND THAT THERE WERE MANY, MANY, COMPLAINTS ABOUT THIS EXACT SAME PROBLEM CONCERNING 1999 - 2003 GMC AND CHEVY PICK UP TRUCKS AND OTHER MODELS. GM CLAIMS THAT YOU WOULD STILL HAVE SOME BRAKES BECAUSE THERE ARE SEPARATE BRAKE LINES TO THE FRONT AND REAR BRAKES. THIS IS TRUE, BUT I LOST SO MUCH FLUID, SO FAST, I HAD NO BRAKES. DOES SOMEONE ALWAYS HAVE TO DIE BEFORE THEY FORCE A RECALL? THERE ARE SO MANY COMPLAINTS ON THIS MATTER AND I KNOW THERE IS AN ON GOING INVESTIGATION BY THE NHTSA. ENOUGH INVESTIGATING, FORCE THE RECALL BEFORE SOMEONE DIES IF THEY HAVEN'T ALREADY.

ON 8/9/15 AT APPROXIMATELY 3:25PM AN INDIVIDUAL PULL OUT IN FRONT OF ME. WHEN I APPLIED THE BRAKES TO KEEP FROM HITTING HIM, THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR BOARD. I NOTICED AT THE TIME THE "SERVICE BRAKE SYSTEM" INDICATION WAS SHOWING ON THE DRIVER CID. I WAS ABLE TO DRIVE THE TRUCK TO A SAFE LOCATION AND PARK IT. I LOOKED UNDER THE VEHICLE AND NOTICED BRAKE FLUID ON THE GROUND UNDER THE RIGHT FRONT WHEEL. THE TOW TRUCK DRIVER ALSO CHECKED AND NOTICED BRAKE FLUID SHOOTING UP WHEN THE HOOD WAS UP. AT THAT TIME, HE NOTICED THE RIGHT FRONT BRAKE LINE HAD RUSTED THROUGH. THE TRUCK WAS THEN TOWED TO CUNNINGHAM GMC IN SPRINGFIELD, TN.

I WAS APPROACHING A STOP LIGHT DRIVING ON A 4 LANE 55 MPH SPEED ZONE. AS I WAS APPROACHING THE STOP LIGHT I STARTING PRESSING ON THE BRAKE PEDAL. THE PEDAL HAD NO RESISTANCE IT KEPT GOING TO THE FLOOR. I STARTED PUMPING THE PEDAL TRYING TO SLOW MY TRUCK DOWN, NO USE. I PUSHED PEDAL ALL THE WAY TO THE FLOOR. THIS SLOWED A LITTLE. BUT NOT ENOUGH. I DOWN SHIFTED THE AUTOMATIC LEVER AND STARTING GUIDING THE TRUCK OFF THE ROAD TO AVOID THE STOPPED VEHICLES. I MISSED THE VEHICLES. LUCKILY I WAS ONLY 3 MILES FROM HOME. I MANAGED TO LIMP HOME BY DRIVING VERY, VERY SLOW AND USING THE GEAR SHIFTER TO SLOW ME DOWN. WHEN INVESTIGATING THE CAUSE AT HOME I FOUND THE BRAKE LINE ON THE RIGHT FRONT HAD RUSTED THROUGH AND THERE WAS A LEAK. ALL THE BRAKE LINES ON THIS TRUCK ARE RUSTED AND IN BAD SHAPE. I CALLED THE DEALER GLENN BUICK GMC WHERE I PURCHASED THE TRUCK NEW IN 2003. I SPOKE TO THE SERVICE PERSONAL "COREY" ABOUT REPAIRING THE RUSTED LINES. HE SAID GMC WAS NOT STANDING BEHIND THIS "FAILURE" ! I WAS ON MY OWN ! SEEMS GMC KNOWS OF THESE FAILURES AND SO DO YOU AND YOU HAVE AGREED NOT TO MAKE THEM STAND BEHIND IT AND YOU HAVE CHOSEN TO ALLOW MORE ACCIDENTS TO HAPPEN ! YOU = NATIONAL HIGHWAY SAFETY WHAT A SHAME ! SHAME ON YOU AND GMC ! HAD I NOT BEEN "LUCKY" THIS COULD HAVE BEEN A TERRIBLE ACCIDENT! ANY HELP IN RESOLVING THIS ISSUE WOULD BE APPRECIATED! THIS ISSUE WILL ONLY GET WORSE ! AS I AM SURE THERE ARE OTHER TRUCKS WITH THIS POTENTIAL PROBLEM WAITING TO HAPPEN!

BRAKE LINE RUSTED THROUGH AND LOST ALL BRAKING CAPABILITY. LUCKLY IT HAPPENED PULLING INTO MY DRIVEWAY AND NOT ON THE HIGHWAY! FUEL LINES RUSTED THROUGH AND LEAKING FUEL PUDDLING ONTO THE GROUND.

TL* THE CONTACT OWNS A 2003 GMC SIERRA. WHILE DRIVING APPROXIMATELY 45 MPH, THE RPMS INCREASED TO 3,500 WITHOUT WARNING. THE DEALER DIAGNOSED THAT THE FUEL LINES WERE RUSTED, FRACTURED, AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 157,000.

I WAS MOVING THE VEHICLE IN THE DRIVEWAY WHEN THE BREAK PEDAL WENT TO THE FLOOR. THE TRUCK STOPPED SO I GOT OUT AND LOOKED UNDER IT AND SAW BREAK FLUID POURING OUT OF A BREAK LINE THAT HAD COMPLETELY RUSTED THROUGH. THE FORMER OWNER HAD ALREADY HAD ANOTHER BREAK LINE REPLACED BECAUSE HIS BREAKS HAD RUPTURED DUE TO THE LINES RUSTING THROUGH WHILE DRIVING AT HIGHWAY SPEEDS AND TOWING A FIFTH WHEEL CAMPER. HE WAS ABLE TO AVOID WRECKING AND CAME TO A STOP. THIS TRUCK HAS LOW MILES AND ABOUT 90% OF ITS USE HAS BEEN DURING THE SUMMER SO IT HAS HAD LIMITED CONTACT WITH SALTED ROADS YET THE ENTIRE UNDERCARRIAGE OF THE VEHICLE IS RUSTING AT AN INCREDIBLE RATE. I AM FORTUNATE THAT I WAS SIMPLY MOVING THE TRUCK RATHER THAN HAULING MY CAMPER ON THE HIGHWAY WHICH IS IT'S TYPICAL USE; I AND/OR OTHERS COULD HAVE BEEN SEVERELY INJURED OR KILLED. THE RUSTING THROUGH OF THE BREAK LINES IS A SAFETY ISSUE!

(ELECTRICAL) AS AN ONGOING ISSUE, THE DASHBOARD GAUGES/INDICATORS (I.E. TACH, SPEEDOMETER, ETC..) WILL SOMETIMES NOT REGISTER UNTIL SEVERAL MINUTES AFTER THE VEHICLE HAS BEEN RUNNING (THIS COULD BE FOR UP TO MILES) IT HAS NOT AFFECTED VEHICLE PERFORMANCE TO DATE. (FUEL/PROPULSION SYSTEM) I HAVE BEGUN HAVING ISSUES WHERE IT GOES INTO "REDUCED ENGINE POWER". FURTHER DIAGNOSTIC ATTEMPTS HAVE LED ME TO BELIEVE THAT IT IS DUE TO A FAULTY THROTTLE POSITION SENSOR (PART OF THE THROTTLE BODY), TAC MODULE, OR APP ASSEMBLY (ACCELERATOR PEDAL). MOST LIKELY CAUSE MAY BE DUE TO THE THROTTLE POSITION SENSOR, AS THIS ISSUE HAS HAPPENED WHEN THE VEHICLE IS ON "CRUISE CONTROL". HOWEVER, DUE TO THE INFERIOR DESIGN OF THE THROTTLE BODY UNIT ITSELF, THE MANUFACTURE HAS MADE IT DIFFICULT OR IF DESIGNED TO BE IMPOSSIBLE TO REPLACE JUST THE TPS, BY RIVETING THE TPS TO THE THROTTLE BODY, AND MAY HAVE TO REPLACE THE WHOLE THROTTLE BODY. I AM HAVING THE VEHICLE SERVICED FOR A COMPLETE DIAGNOSTIC AND REPAIR, AND WILL ELABORATE FURTHER UPON SUCCESSFUL REPAIR IF DESIRED. *TR

COMPLETE BRAKE FAILURE. ALL BRAKE LINES RUSTED OUT. HAD TO USE THE EMERGENCY BRAKE TO STOP. BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR. ALL THE BRAKE FLUID WAS GONE. SPENT $1008 TO FIX THE VEHICLE. NO PREVIOUS WARNING, NO MESSAGE UNTIL THERE WAS THE COMPLETE BRAKE FAILURE. *TR

TL* THE CONTACT OWNS A 2003 GMC SIERRA 1500. WHILE DRIVING AT 65 MPH, THE BRAKE PEDAL WAS DEPRESSED BUT THE VEHICLE FAILED TO STOP. THE CONTACT HAD TO ENGAGE THE EMERGENCY BRAKE IN ORDER TO STOP THE VEHICLE. IN ADDITION, THE CONTACT STATED THAT BRAKE FAILURE WAS DISPLAYED ACROSS THE MESSAGE BOARD AND A CHIME WAS HEARD. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC. THE MECHANIC DIAGNOSED THAT THE BRAKE LINES WERE CORRODED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 112,000. ..UPDATED 05-26-15 *BF THE CONSUMER STATED BOTH BRAKE LINES FAILED. UPDATED 11/20/2015*JS

TL* THE CONTACT OWNS A 2003 GMC SIERRA. WHILE DRIVING APPROXIMATELY 60 MPH, THE BRAKES WERE DEPRESSED AND TRAVELED ABRUPTLY TO THE FLOOR. THE VEHICLE FAILED TO COME TO A STOP UNTIL THE EMERGENCY BRAKE WAS ENGAGED AS THE BRAKE PEDAL WAS APPLIED. THE VEHICLE WAS TOWED TO THE RESIDENCE. THE CONTACT DISCOVERED THAT THE ENTIRE BRAKE LINES FRACTURED DUE TO CORROSION. THE VEHICLE NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 73,000.

CAME TO INTERSECTION FOR TURN, BROKE AND PEDAL WENT TO FLOOR. *TR

WHILE DRIVING TO THE STORE I APPLIED THE BRAKE AND IT WENT STRAIGHT TO FLOOR WITHOUT ANY PRE-WARNING OF A BRAKE ISSUE. I WAS ABLE TO STOP WITHOUT CRASHING AND FOUND THAT THE BRAKE LINE ROUTED OVER THE GAS TANK RUSTED THROUGH SPILLING OUT BRAKE FLUID WHICH CAUSED THE BRAKE RESERVOIR TO EMPTY. AFTER DOING SOME RESEARCH NHTSA IS WELL AWARE OF THE RUSTED BRAKE LINES ON GM MODELS, SO I AM NOT TELLING YOU ANYTHING NEW. I EXPECT ALTERNATORS, STARTER MOTORS, AND OTHER MECHANICAL COMPONENTS TO FAIL AND NEED REPLACED BUT BRAKE LINES SHOULD BE MANUFACTURED USING STAINLESS STEEL. HOW CAN THIS BE ANY DIFFERENT THAN A CAR IGNITION TURNING OFF CAUSING POTENTIAL CRASHES AND LOSS OF LIFE. NHTSA SHOULD HAVE GM RECALL VEHICLES AND/OR REIMBURSE OWNERS FOR THIS HIGHLY POTENTIAL SAFETY ISSUE. *TR

WHILE TRAVELING IN MY 2003 GMC SIERRA TRUCK AT APPROXIMATELY 45 MPH I STEPPED ON THE BRAKE PEDAL TO STOP AT A STOP SIGN AND THE PEDAL WENT 3/4 OF THE WAY DOWN TO THE FLOOR, THEN THE BRAKE LIGHT CAME ON AND THE TRUCK DID NOT STOP AS QUICKLY AS IT USUALLY DOES ( GLAD I WAS NOT GOING ANY FASTER) . UPON CHECKING THE TRUCK IT WAS DISCOVERED THAT THE FRONT DRIVERS SIDE STEEL BRAKE LINE HAD A HOLE IN IT DUE TO CORROSION AND THERE WAS NO BRAKE FLUID IN THE MASTER CYLINDER . *TR

TL* THE CONTACT OWNS A 2003 GMC SIERRA 1500. WHILE DRIVING 40 MPH, THE CONTACT'S VEHICLE CRASHED INTO THE PASSENGER SIDE OF ANOTHER VEHICLE. THE AIR BAGS FAILED TO DEPLOY. THE CONTACT SUSTAINED INJURIES TO THE FACE, KNEE, AND BACK THAT REQUIRED MEDICAL ATTENTION. IN ADDITION, THE PASSENGER SUSTAINED HIP AND SHOULDER INJURIES THAT REQUIRED MEDICAL ATTENTION. A POLICE REPORT WAS FILED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 177,000.

TRUCK WAS BEING DRIVEN IN TRAFFIC AND AS APPROACHING STOP LIGHT AND BRAKES WERE APPLIED PETAL WENT ALL THE WAY TO FLOOR AND HAD TO SWERVE TO MISS STOPPED TRAFFIC. UPON INSPECTION BRAKE LINE ON DRIVERS FRONT SIDE OF TRUCK AND LAYING ON TOP OF THE FRAME WAS RUSTED ALMOST COMPLETELY IN HALF! QUICK THINKING AVOIDED ACCIDENT .THIS TRUCK HAS ONLY BEEN DRIVEN ON CITY STREETS AND NEVER OFF ROAD FOUR WHEELING AND FEEL THIS IS MANUFACTURING DEFECT AS STAINLESS STEELS LINES SHOULD NOT RUST IN HALF IF IN FACT THEY ARE STAINLESS STEEL TO BEGIN WITH.TRUCK IS AT GMC NOW TO BE REPAIRED. *TR

WHILE HAVING MY VEHICLE CHECK OVER FOR THE WINTER, THE MECHANIC INFORM ME THAT THE FRONT BRAKE LINES ARE VERY RUSTY AS WELL AS THE FUEL LINES AND THE COOLING LINES GOING TO THE TRANSMISSION. THIS SITUATION IS VERY DISTURBING SINCE I HAVE VERY LOW MILEAGE. THE TUBING USED FOR THE BRAKE AS WELL AS THE FUEL LINES SHOULD BE ABLE TO WITHSTAND RUSTING FOR THE LIFE OF THE VEHICLE. IF THE MATERIAL USED BY GM WAS NOT UP TO SPECIFICATION AS FAR AS CORROSION PROTECTION EITHER COMPENSATION TO REPAIR IT IS IN ORDER A RECALL SHOULD BE MADE.

I WAS TRAVELING IN RULE AREA OF MICH. AFTER DARK,A DEER JUMP OUT IN FRONT OF ME! I HIT THE BRAKES,A BRIEF BRAKE SURGE, THEN THE PEDAL WENT TO THE FLOOR! NO BRAKES! THE BRAKE LINES UNDER THE DRIVERS SEAT AREA WERE RUSTED THROUGH! I STOP AT A GAS STATION. I FOUND BRAKE FLUID ALL OVER AND A MAN ASKED ME WHAT HAD HAPPENED,I TOLD HIM WHAT I FOUND , HE AND I COULDN'T BELIEVE THEY WERE SO RUSTED OUT ! MY TRUCK IS IN VERY GOOD SHAPE! EXCEPT FOR THE BRAKE LINES! IT'S GOT A STAINLESS STEEL EXHAUST SYSTEM BUT THEY SCRIMP ON ONE OF THE MOST CRITICAL SYSTEMS FOR SAFETY ! UNBELIEVABLE! BY THE GRACE OF GOD I DIDN'T HIT THE DEER! BUT WHAT IF IT HAD HAPPENED IN TOWN OR IF THE DEER WAS A CHILD! THANK GOD IT HAPPENED THE WAY IT DID AND NO ONE GOT HURT! *TR

TL* THE CONTACT OWNS A 2003 GMC SIERRA. WHILE DRIVING APPROXIMATELY 25 MPH, THE BRAKE LINES FRACTURED WHEN THE BRAKE PEDAL WAS DEPRESSED. THE CONTACT USED THE PARKING BRAKE TO STOP THE VEHICLE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS UNKNOWN.

BRAKE LINES ARE HEAVILY RUSTED, TRUCK IS BEYOND WARRANTY, DEALER WILL NOT REPLACE UNLESS RECALLED. *TR

ON 11/11/2014, TRUCK SUDDENLY VEERED TO LEFT, CROSSED MIDDLE OF ROAD AND WENT HALFWAY INTO DITCH, ROAD DID HAVE A SMALL AMOUNT OF SNOW[1/2 INCH], THIS HAPPENED JUST AS I TOPPED A SMALL HILL. ON 11/16/2014 AGAIN AS I TOPPED A HILL ON A CURVE THE TRUCK SUDDENLY VEERED TO THE LEFT, CROSSED THE MIDDLE OF THE ROAD AND DID GO COMPLETELY IN THE DITCH. ON 11/30/2014 AS I BACKED OUT OF THE GARAGE, THE BRAKE PEDAL WENT TO THE FLOOR AND HAD A HORRIBLE NOISE WHEN I APPLIED THE BRAKE. I MADE AN APPOINTMENT WITH MY MECHANIC AND HE FOUND THE BRAKE CALIPER WAS FROZE UP AND SHEARED OFF THE BRAKEPAD AND THIS RUINED THE BRAKE ROTOR, THIS OF COURSE CAUSED THE LOSS OF BRAKES ON THE RIGHT REAR SIDE, WHICH MUST HAVE BEEN PULLING ME OFF THE ROAD. LUCKILY WE SUFFERED NO SERIOUS INJURIES AND NO OTHER VEHICLES WERE ON THE ROAD. *TR

LOUD NOISES FROM LEFT REAR WHEEL, LIKE A LOOSE PART, THEN A GRINDING SOUND. SUSPECT IT WAS NOT FIXED IN RECALL. *TR
