2003 GMC Sierra 2500 Problems

BRAKES ARE SPONGY NOT RIGHT POWER STEERING WHINES AS DO BRAKES

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.

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?

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.

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.

I OWN A 2003 GMC DURAMAX 167000 MILES, IT HAS BEEN A GREAT TRUCK UNTIL RECENTLY, AFTER ENGINE GETS HOT IT WILL NOT START BACK UP UNTIL IT HAS COOLED OFF! HAVE NOT BEEN ABLE TO FIND THE PROBLEM YET, BUT FOUND A LOT OF COMPLAINTS ONLINE FROM PEOPLE WITH THE SAME PROBLEM, [INJECTORS], VERY EXPENSIVE TO REPAIR!!! THIS PROBLEM IS VERY FRUSTRATING, WOULD BE GREAT IF GENERAL MOTORS WOULD CORRECT THIS PROBLEM!!!! *TR

I HAVE A 2003 SIERRA PICKUP 4X4, 64,000 MILES. IT HAS NEVER BEEN OFF ROAD. 4 WHEEL DRIVE HAS ONLY BEEN ENGAGED LESS THAN A DOZEN TIMES SINCE THE VEHICLE WAS PURCHASED. I AM THE ORIGINAL OWNER. MILEAGE HAS BEEN APPROX 50/50 BETWEEN HIGHWAY AND CITY DRIVING. ON A RECENT TRIP FROM PRESCOTT AZ TO PHOENIX AZ, THE PASSENGER SIDE HUB ASSEMBLY FAILED ON 2003 GMC SIERRA PICKUP; 2500HD WITH DURAMAX DIESEL ENGINE. ONCE HUB ASSEMBLY FAILED, THE RIGHT FRONT AXLE BROKE AND BASICALLY ALLOWED FOR THE WHEEL TO BECOME DETACHED FROM THE VEHICLE. THE HUB ASSEMBLY FAILED WITHOUT WARNING AND HAD IT FAILED APPROX 10-15 MILES EARLIER IT WOULD HAVE RESULTED IN LOSS OF CONTROL OF THE VEHICLE COMING DOWN THE MOUNTAINS BETWEEN PRESCOTT AZ AND PHEONIX AZ. THE VEHICLE HAS BEEN MAINTAINED ACCORDING TO FACTORY SPECIFICATIONS. I HAD THE VEHICLE TOWED TO THE DEALER I PURCHASED IT FROM; PEORIA PONTIAC GMC, PEORIA, AZ. THE SERVICE DEPARTMENT DIAGNOSED THE HUB ASSEMBLY FAILURE AND AXLE BREAKAGE ON THE PASSENGER SIDE. I ASKED THEM TO CHECK THE DRIVER'S SIDE HUB ASSEMBLY; IT WAS ALSO BAD. I ASKED THE SERVICE PERSON IF THERE WAS SOME ADDITIONAL MAINTENANCE THAT I COULD HAVE DONE TO PREVENT THIS PROBLEM. THE RESPONSE WAS A DISCONCERTING NO; THIS JUST SEEMS TO HAPPEN ON SOME OF THE PICKUPS. I HAVE PAID TO HAVE BOTH FRONT HUB ASSEMBLIES REPLACED AND THE PASSENGER AXLE; APPROX $2500. MY BIGGER CONCERN IS FIRST THAT 65000 CITY & HIGHWAY MILES SEEMS PRETTY LOW FOR A FAILURE POINT OF SOMETHING SO CRITICAL AS THE STEERING AND CONTROL OF THE VEHICLE. SECONDLY THAT THERE IS APPARENTLY NO FIX OR ADDITIONAL EXPLANATION OF HOW TO AVOID THIS PROBLEM ON THIS VEHICLE. MY IMMEDIATE SUSPICION IS THAT GM INADEQUATE HUB ASSEMBLIES ON THEIR DIESEL PICKUPS AND ARE NOT ABLE TO HANDLE THE ADDITIONAL STRESSES OF THE HEAVY WEIGHTS AND TORQUES, ETC. I WAS TRAVELING WITH MY ELDERLY PARENTS AND WE WERE LITERALLY LUCKY THAT THE FAILURE OCCURRED ON A FLAT OPEN AREA OF ROAD AND I WAS ABLE TO GET THE VEHICLE TO A SAFE STOP. *JB

TL* THE CONTACT OWNS A 2003 GMC SIERRA 2500 HD. THE CONTACT STATED THAT THE ENTIRE BOTTOM OF THE TRUCK BED WAS RUSTED, INCLUDING THE FUEL TANK. THE VEHICLE WAS TAKEN TO A DEALER (FREEDOM CHEVROLET, 7052 W 48TH ST, FREMONT, MI 49412, 321-403-0016) WHERE IT WAS DIAGNOSED THAT CHEAP METAL WAS USED ON THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND DID NOT PROVIDE ANY ADDITIONAL INFORMATION. THE FAILURE MILEAGE WAS APPROXIMATELY 120,000.

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

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

I ENTERED THE TRUCK STEPPED ON THE CLUTCH PEDAL, SHIFTED INTO REVERSE AND STARTED TO EASE THE CLUTCH OUT WHEN THE PEDAL WENT ALL THE WAY TO THE FLOOR BOARD. THE VEHICLE IMMEDIATELY CHIRPED THE BACK TIRES AT NO MORE THAN 950 R.P.M.'S AND BEGAN TO IMMEDIATELY GO BACKWARDS TOWARDS ANOTHER VEHICLE IN MY DRIVEWAY. I QUICKLY STEPPED ONTO THE BRAKE AND STALLED THE VEHICLE TO A STOP. I THEN PROCEEDED TO LOOK UNDER THE DASH TO SEE WHAT HAD "POPPED" AND FOUND THAT I COULD SEE LIGHT THROUGHOUT THE FIREWALL, AS I MOVED THE PEDAL UP AND DOWN. I OPENED THE HOOD TO FIND THAT THE BLACK PLASTIC FLANGE THAT THE CLUTCH MASTER CYLINDER MOUNTS TO HAD BROKEN OR SHATTERED RELEASING THE MASTER CYLINDER THEREFORE, COMPLETELY DISENGAGING THE CLUTCH. HAD I NOT BEEN QUICK TO REACT, I WOULD HAVE STRUCK ANOTHER VEHICLE IN THE SIDE CAUSING EXTENSIVE DAMAGE. HAD I BEEN IN 1ST GEAR WHEN THE FAILURE OCCURRED I WOULD HAVE LUNGED FOWARD AT THE END OF MY DRIVEWAY AND OFF A 10' LEDGE STRAIGHT DOWN INTO MY NEIGHBORS BACKYARD, RESULTING IN PERSONAL AND PROPERTY DAMAGE. THIS VEHICLE HAS ONLY APPROX 104 THOUSAND MILES. THIS WAS A POOR DESIGN AND HAS FAILED IN A VERY DANGEROUS MANNER. THIS NEEDS TO BE RECALLED IMMEDIATELY. *TR

WHILE DRIVING IN RAIN WITH WIPERS ON INTERMITTENT, THEY SUDDENLY RAN FULL-TIME AND WOULD NOT SHUT OFF. ONLY WAY TO TURN OFF WIPERS IS PULL THE FUSE. WITH FUSE OUT, WIPERS DO NOT WORK AT ALL, AND DRIVER'S DOOR MUST BE OPENED TO ACCESS FUSE AREA. THIS IS A HAZARD, AS WIPERS ARE NOT AVAILABLE WHILE DRIVING WITHOUT OPENING DOOR. *TR

DT*: THE CONTACT STATED THE EXTERIOR PASSENGER SIDE REAR MIRROR WAS ROUNDED AND DID NOT HAVE A STATEMENT INDICATING OBJECTS IN THE REAR VIEW MIRROR MAY APPEAR CLOSER THAN THEY ARE. DUE TO THE ROUNDED DESIGN, IT CREATED A BLIND SPOT. THE MANUFACTURER WAS ALERTED.

THE VEHICLE HAS HAD FAILURE OF THE AIR CONDITIONER AND HEATING. RESULTED IN FIRED IN THE DASH BOARD WIRING TWICE. HAD BEEN IN THE SHOP FOR HEATING AND AIR CONDITIONER EIGHT TIMES. *JB

INSTRUMENT PANEL CLUSTER COMPONENTS FAILED THUS ALL GAUGES ON DASH BOARD WENT "FLAT"/BACK TO -0-; VEHICLE DID OPERATE HOWEVER COULD NOT EVEN READ HOW MUCH GAS WAS IN TANK. ALSO AS OF MILEAGE OF 13312 NOTICE VEHICLE BEGAN TO USE OIL, AS OF 26300 AFTER WATCHING THE VEHICLE NOTICED THAT IT WAS EXTREMELY LOW; APPARENTLY THE VEHICLE HAS BEEN LEAKING OIL ON THE INTAKE - LOOSING ALMOST 2 QUARTS OF OIL - ON A NEWER VEHICLE IT SHOULD NOT BE USING THIS MUCH OIL. *LA

I WAS HEADING NORTH BOUND ON I-45 NEAR NORTH AVENUE IN MILWAUKEE, WI WHEN IT BEGAN TO RAIN SLIGHTLY. IT WAS APPROXIMATELY 3:28 AM. I SLOWED DOWN TO 50 THE SPEED LIMIT WAS 55 AND THE I TURNED ON MY FOG LIGHTS TO HELP ME SEE BETTER BY THE TIME I GOT TO CAPITAL DRIVE IT WAS A COMPLETE DOWNPOUR. RAINING VERY HARD. I WAS IN THE VERY INSIDE LANE IE: "THE FASTLANE" I WAS APPROACHING THE HAMPTON AVENUE EXIT AND THERE WAS A SEMI ON MY RIGHT HIS REAR TANDOM AXLES WHERE JUST TO THE RIGHT OF MY PASSENGER SIDE FRONT TIRE AND HE WAS COMING OVER TO MY LANE. I HIT THE BREAKS AND WAS STEERING TO THE RIGHT TO GO TOWARDS THE MIDDLE LANE. MY BRAKES LOCKED UP AND THE ABS BRAKES NEVER TURNED ON. THIS IS A 2003 GMC 2500 HD CREW CAB ALL THE WEIGHT IS IN THE FRONT AN THE CAB. WHEN I HIT THE BRAKES I WAS HEADING FOR THE RIGHT LANE AND THE TRUCK TURNED 90DEG TO THE LEFT AND HIT THE CONCRETE DIVIDER WALL. AT FULL 50 MPH SPEED AND THE PASSENGER REAR CAME AROUND AND HIT THE WALL AS WELL. THE AIR BAG NEVER DEPLOYED. I HIT THE WALL WITH SO MUCH FORCE THAT THE BED OF THE TRUCK EMBEDDED IN THE REAR OF THE CAB. MIND YOU THIS WAS A 3/4 TON TRUCK IT TAKES A LOT OF FORCE TO HAVE THIS HAPPEN. I FEEL THAT IF MY ABS BREAKS HAVE PULSATED 10 TIMES PER SECOND PER WHEEL I WOULD HAVE CAME TO A CONTROLLED STOP ON THE RIGHT SHOULDER OF THE ROAD WITH THE TRAJECTORY I WAS HEADING. THE AIR BAGS NEVER DEPLOYED. GOOD THING I WAS WEARING MY SEAT BELT. THE TIME OF THE CRASH WAS. 3:45 AM. *JB

I HAVE A 2003 GMC 2500 HD DURAMAX DIESEL. MY COMPLAINT IS THE AIR CONDITIONING DOESN'T SEEM TO COOL VERY WELL. I HAD A 2002 MODEL AND IT COOLED ALOT BETTER. I AM NOT SURE WHAT WAS CHANGE OTHER THAN THIS IS A DUAL ZONE SYSTEM BUT IS NOT FOR THE BETTER. I WOULD LIKE IF GMC WOULD CHANGE IT BACK TO THE WAY IT WAS IN 2002, ESPECIALLY FOR THOSE WHO LIVE IN THE SOUTHERN STATES. I AM A PROFESSIONAL AND WHEN I CLIMB INTO MY TRUCK ON A HOT DAY I SOAK A PERFECTLY GOOD SHIRT WAITING ON IT TO COOL DOWN IN THE CAB. THIS IS PATHETIC TO THINK THAT GMC'S SLOGAN IS "PROFESSIONAL GRADE" NOT AS FAR AS THE AC! *NLM
