2003 GMC Sierra 2500 Owner Complaints

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.

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?

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.

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

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
