2003 GMC Sierra engine problems

ENGINE

I WROTE GM ON OCTOBER 26, 2013 ABOUT MY 2003 GMC SIERRA DURAMAX DIESEL 6.6L 6L THAT JUST RECENTLY STARTED BILLOWING BLUISH BLACK SMOKE CONSTANTLY FROM THE EXHAUST AND COSTING AN EXORBITANT AMOUNT OF MONEY IN GAS. I TOOK IT TO THE DEALER (QUALITY BY DILORENZO IN ALBUQUERQUE, NEW MEXICO) AND THEY INFORMED ME THAT THERE WAS A BULLETIN ISSUED IN OCTOBER 2006 FOR LEAKING FUEL INJECTORS. THEY DIAGNOSED MY TRUCK WITH THE EXACT FUEL INJECTOR PROBLEM. THE TRUCK ONLY HAS 83,502 MILES ON IT AND I'VE BEEN INFORMED THAT THE NEXT TIME I TAKE IT FOR AN EMISSIONS TEST (A REQUIREMENT IN NEW MEXICO) IT WILL FAIL. I FINALLY SAVED UP ENOUGH MONEY TO GO AN OUTSIDE REPAIR SHOP ON JULY 15, 2014 TO GET MY FUEL INJECTORS REPLACED AND THE TOTAL CAME TO $4763.78. I FOUND OUT THAT THERE WERE TWO STRIPPED BOLTS INDICATING THAT THE FUEL INJECTORS WERE PREVIOUSLY REPAIRED (ADDITIONAL COST OF$12 EACH TO REPLACE THE 8 BOLTS). I CALLED THE ORIGINAL OWNER AND HE TOLD ME THAT THE INJECTORS WERE REPAIRED UNDER THE ORIGINAL BULLETIN (04039) IN JUNE 2005 AT TILLERY MOTORS IN BELEN NM. THEREFORE, THE FUEL INJECTORS WERE NEVER REALLY REPAIRED PROPERLY IN THE FIRST PLACE. I HAVE SPOKE TO ANOTHER WOMEN ([XXX]) AT THE GM CUSTOMER SERVICE CENTER. SHE IS AGAIN ELEVATING THIS ISSUE TO A SPECIALIST UNDER GM ID [XXX] FOR REIMBURSEMENT OF THE TOTAL COST (STANDARD 24-48 HOUR CALL BACK). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

MY VEHICLE BEGAN LOSING COOLANT. I TOOK THE VEHICLE TO A MECHANIC, WHO HAS TOLD ME THAT THE CYLINDER HEAD IS CRACKED AND LEAKING. THIS IS DUE TO FAULTY CASTING ON THE CYLINDER HEAD.THE COOLANT IS LEAKING INTO THE HEADS, AND CAUSING THE OIL TO LOSE IT'S ABILITY TO PROTECT THE ENGINE FROM WEAR. I HAVE SEEN THAT THERE ARE MANY PEOPLE WITH THIS ISSUE, AND IT IS A VERY COSTLY REPAIR.

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.

I OWN A 2003 GMC SIERRA WITH A DIESEL ENGINE. I HAVE HAD TO REPLACE THE BLOCK HEATER 5X IN THE LAST 3 YEARS. IT QUITS ABOUT EVERY 4 MONTHS DURING THE "WINTER MONTHS" OR THE FIRST TIME I PLUG IT IN AFTER THE SUMMER IT FAILS TO WORK.

DT: THE CONTACT COMPLAINED ABOUT MANY DEFECTS WITH THIS VEHICLE. THE SPEEDOMETER CONTINUALLY HAD AN INACCURATE READ OUT WHILE DRIVING. THE DEALERSHIP BELIEVED THIS FAILURE COULD BE RELATED TO THE WIRING HARNESS. SINCE THEY WERE UNABLE TO DUPLICATE THE PROBLEM NO REPAIRS WERE DONE. ALSO, THE VEHICLE STALLED AT VARIOUS SPEEDS WITHOUT WARNING. WHILE THE STALLING OCCURRED THE CONTACT PRESSED HARD ON THE BRAKES TO ELEVATE THE STALLING. HE BELIEVED THIS WAS DUE TO THE POWER BRAKES. THE VEHICLE STALLED ON OCCASION AND WOULD NOT IMMEDIATELY RESTART. THE DEALERSHIP MADE NUMEROUS ATTEMPTS TO CORRECT THIS PROBLEM W AND ALL ATTEMPTS HAVE BEEN UNSUCCESSFUL. THIS INCLUDED REPLACING THE FUEL PUMP AND ELECTRICAL CONTROL MODULE.

ON FEBRUARY 18, 2003 I PURCHASED A NEW 2003 TRUCK THE TRUCK CAME WITH THE SERVICE LIGHT ON. WHEN DRIVING THE 4X4 WHEEL LIGHT WOULD COME ON AS IF THE TRUCK WAS IN 4 WHEEL DRIVE. THE LIGHT WOULD GO OFF AFTER STOPPING AND SHUTING THE TRUCK OFF FOR AT LEAST 15 MINUTES. I WENT TO THE DEALER AND THEY SAID THERE WAS NO FIX AT THIS TIME AND THEY GAVE ME A SERVICE BULLETIN, FILE IN SECTION:4-DRIVELINE AXLE BULLETIN NO:03-04-21-001 DATE: FEBRUARY, 2003. I WAS TOLD THAT IF I WAS WORRIED ABOUT THE 4X4 ENGAGING ON ITS OWN WHILE DRIVING THE ONLY THING THEY COULD DO WAS TO DISENGAGE THE 4X4 WHEEL DRIVE AT THIS TIME.I NEED TO HAVE THE USE OF THE 4X4 WHEEL DRIVE AS I OWN A LARGE CONCRETE CONSTRUCTION COMPANY AND USE MY TRUCK ALL DAY LONG ON JOBSITES. I LEFT THE DEALER NOT KNOWING WHAT TO DO. I WAS WORRIED ABOUT DAMAGING THE 4X4 UNIT EVEN MORE ON MY NEW TRUCK. SO TWO WEEKS LATER I WAS TIRED OF WORRYING, SO I TOOK THE TRUCK BACK TO THE DEALER AND THEY DISENGAGED THE 4 WHEEL DRIVE. THE SERVICE 4X4 WHEEEL LIGHT IS STILL ON AT THIS TIME. I ALSO FILED A COMPLAINT WITH GMC ON 3/27/03 #1-85090755. I HAVE NOT HEARD FRON THE DEALER IN ONE MONTH.
