ALSO HAD CONTACTED GM ABOUT ORIGINAL WORK RE: POSSIBLE WARRANTY. *TR UPDATED 07/25/12 *BF THE CONSUMER HAS SINCE TRADED THE VEHICLE. UPDATED 07/31/12

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

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. *NM

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...
