2003 GMC SIERRA 2500 Complaints

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 2500. THE CONTACT STATED THAT AFTER INSPECTING THE VEHICLE, HE NOTICED THAT THE OIL LEVEL WAS ELEVATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE FUEL INJECTORS NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE RECURRED AFTER APPROXIMATELY 30,000 MILES AND THE VEHICLE WAS EMITTING SMOKE. THE VEHICLE WAS REPAIRED WITH NEW FUEL INJECTORS BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 209,000.

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.

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

TL* THE CONTACT OWNS A 2003 GMC SIERRA 2500. WHILE DRIVING VARIOUS SPEEDS, THE CONTACT NOTICED EXCESSIVE FUMES COMING FROM THE EXHAUST OF THE VEHICLE. THE VEHICLE WAS TAKEN TO A DEALER. THE TECHNICIAN DIAGNOSED THAT FOUR FUEL INJECTORS NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED, HOWEVER, THE FAILURE RECURRED ON MULTIPLE OCCASIONS. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 118,736.

THE FRONT AND REAR BUMPERS HAVE RUSTED SO BAD THAT THEY HAVE BIG HOLES IN THEM. I WAS TOLD I HAVE TO REPLACE THEM BOTH BEFORE I CAN GET AN INSPECTION STICKER ON THE PICK UP, AT THE COST OF OVER $1000.00 FOR PARTS AND LABOR. I HAVE SEEN MANY MORE PICK UPS WITH THE SAME RUSTED BUMPERS. IS THERE A RECALL FOR BUMPER REPLACEMENT ON THESE PICKUPS?? *TR

BRAKE LINE LEAKS, BRAKE STOPPED WORKING BECAUSE OF RUSTED BRAKE LINES. ALSO FUEL AND TRANSMISSION LINES ARE RUSTED BADLY. *TR

COMPLETE BRAKE FAILURE WHILE PULLING A 10000 POUND TRAILER IN CAMP GROUND. THE BRAKE LINES UNDER THE DRIVERS SIDE BROKE APPEARED TO BE CORROSION. TRUCK WAS TOWED TO REPAIR LOCATION. ALL BRAKE LINES WERE REPLACED, COST $ 950 DOLLARS. *TR

II PUT NEW BRAKE CALIPERS ON MY TRUCK TODAY AND HAD MY WIFE PUMPING THE BRAKE PEDDLE AS I BLED THE BRAKES AND GOT TO THE LAST CALIPER REARS THEN THE 2 FRONTS WHEN SHE TOLD ME THE BRAKE PEDDLE WAS NOT HOLDING LIKE IT WAS , AND THEN SMOKE CAME OUT FROM UNDER THE TRUCK AND I LOOKED UNDERNEATH & SEEN BRAKE FLUID EVERYWHERE BELOW DRIVERS DOOR THE FLUID UNDER PRESSURE BLEW OVER AGAINST THE HOT ENGINE COMPONENTS AS U HAVE TO RUN ENGINE WHEN BLEEDING THE LINES LUCKY I GUESS IT DID NOT CATCH FIRE, BUT AFTER I GOT ON THE INTERNET TRYING TO FIND A REPLACEMENT I FOUND THAT IS A COMMON PROBLEM , I DID SEE THE OTHER LINES LOOKED BAD ALSO THE FUEL LINES LOOKED THE SAME GOOD THING IT HAPPENED IN THE DRIVEWAY AT HOME . MAYBE WOULD HAVE BEEN BETTER OFF IF IT BURNT DOWN , G.M SHOULD FIX ALL OF THESE PROBLEMS WITH THESE TRUCKS ON THEIR DIME AS MUCH AS THESE TRUCKS COST. !! *TR
