2003 GMC SIERRA 2500 Recalls, Complaints & Safety

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?

THE HORN QUITS WORKING AND THIS CREATES A HUGE SAFETY ISSUE. ONLINE SEARCH SHOWS THIS IS A COMMON PROBLEM AND THE DEALER IS UNABLE TO FIX IT.

BRAKES ARE SPONGY NOT RIGHT POWER STEERING WHINES AS DO BRAKES

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.

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.

TL* THE CONTACT OWNS A 2003 GMC SIERRA 2500. WHILE DRIVING AT ANY SPEED, THE VEHICLE STALLED, LOST POWER, AND THE SERVICE ENGINE LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO WAS UNABLE TO DIAGNOSE THE FAILURE. THE FAILURE RECURRED.

Fire

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

CAME TO INTERSECTION FOR TURN, BROKE AND PEDAL WENT TO FLOOR. *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

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

TL* THE CONTACT OWNS A 2003 GMC SIERRA 2500 HD. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 10 MPH, THE BRAKE PEDAL TRAVELED TO THE FLOORBOARD WHEN DEPRESSED. THE VEHICLE EVENTUALLY CAME TO A STOP AND WAS TAKEN TO AN INDEPENDENT MECHANIC. THE TECHNICIAN DIAGNOSED THAT BOTH REAR BRAKE LINES WERE CORRODED AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOT NOTIFIED OF THE DEFECT. THE APPROXIMATE FAILURE MILEAGE WAS 150,000. UPDATED 08/12/2014*LJ

WHEN PLACED IN PARK THEN TURNED OFF THE KEY WOULDN'T COME OUT OF THE IGNITION, WHEN PLACED IN DRIVE WHILE RUNNING THE KEY WOULD COME OUT FREELY. *TR

TL* THE CONTACT OWNS A 2003 GMC SIERRA 2500. THE CONTACT STATED THAT THERE WAS A LOSS OF POWER WHILE TRAVELING AT ANY SPEED. THE WARNING LIGHT ILLUMINATED FOR LOSS OF POWER INTERMITTENTLY. THE CONTACT HAD TO DEPRESS THE ACCELERATION PEDAL TO THE FLOORBOARD TO ACCELERATE ON MORE THAN ONE OCCASION BUT TO NO AVAIL. THE VEHICLE CONTINUED TO STALL WITHOUT WARNING. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER MORE THAN FIVE TIMES, WHO WAS NOT ABLE TO REPLICATE OR DETERMINE THE CAUSE OF THE FAILURE. THE VEHICLE HAD ALSO BEEN TAKEN TO THE DEALER FOR DIAGNOSIS BUT TO NO AVAIL. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS NOT AVAILABLE.

DRIVING TO WORK ONE DAY, A CAR IN FRONT OF ME SUDDENLY STOPPED TO TURN LEFT. I HIT MY BRAKES AND FELT A "POP" AND THE BRAKE PEDDLE WENT STRAIGHT TO THE FLOOR, NO BRAKES. I WAS TRAVELING ABOUT 55 MPH SO AT THAT POINT, I AM A 55 MPH SPEAR ON WHEELS. I SWERVED TO THE RIGHT AND DROVE ACROSS SOMEONE'S DRIVEWAY AND THROUGH THEIR YARD. THIS WEEKEND WAS THE CITY WIDE GARAGE SALES, AND THANKFULLY, THESE FOLKS WERE NOT HAVING A SALE IN THEIR DRIVEWAY OR YARD, OR ELSE THIS COULD HAVE BEEN A TERRIBLE ACCIDENT. THE ONLY RUST ISSUE WITH THIS TRUCK IS THE BRAKE LINES AND FUEL LINES. IF YOUR LINES RUST BEFORE YOUR BODY RUST, THEN I FEEL THERE IS A SERIOUS DESIGN FLAW. IF IT WAS SOMETHING ELSE RUSTING THEN IT WOULDN'T BE AS BIG OF A DEAL. BUT WHEN YOU ARE TALKING BRAKE LINES, IT IS JUST A MATTER OF TIME BEFORE THIS FLAW CAUSES ANOTHER CATASTROPHIC BRAKE FAILURE, LEADING TO AN ACCIDENT INVOLVING SERIOUS INJURY OR DEATH. A 10 YEAR OLD TRUCK SHOULD NOT HAVE THIS PROBLEM. I HAVE OWNED VEHICLES THAT WERE 15, 20 YEARS OLD AND HAVE NEVER HAD TO REPLACE BRAKE LINES. SOMEONE'S LIFE IS WORTH SO MUCH MORE THAN A CHEAPLY MADE BRAKE LINE. *TR

I WAS DRIVING MY 03 SIERRA, APPROACHING A STOPLIGHT AT A BUSY INTERSECTION WHEN I APPLIED THE BRAKES. THE TRUCK BEGAN TO SLOW AT FIRST BUT THEN THE PEDDLE IMMEDIATELY WENT COMPLETELY TO THE FLOOR. I BEGAN TO PUMP IT BUT THERE WAS NO RESPONSE. I WAS HEADING TOWARD THE INTERSECTION, THE LIGHT WAS RED, WITH BUSY CROSS TRAFFIC. THE STREET I WAS ON IS NARROW AND STEEP AND I BEGAN TO PICK UP SPEED. I SHIFTED THE TRANS INTO THE LOWEST GEAR AND STEPPED ON THE EMERGENCY BRAKE. THE TRUCK FINALLY CAME TO A STOP IN THE MIDDLE OF THE INTERSECTION, AS ONCOMING CARS LUCKILY AVOIDED HITTING ME. WHEN I WENT TO MY MECHANIC TO ARRANGE TO HAVE THE TRUCK TOWED, HE KNEW IMMEDIATELY WHAT THE PROBLEM WAS. HE TOLD ME, SIGHT UNSEEN, THAT THE BRAKE LINE UNDER THE DRIVER'S SIDE HAD RUPTURED. LATER, UPON INSPECTION, HE WAS CORRECT. HE ALSO TOLD ME THAT THIS WAS A VERY COMMON PROBLEM WITH THAT YEAR. HE REPLACED THE LINE AND I THOUGHT THAT HAD SOLVED THE PROBLEM; UNTIL TWO DAYS AGO. AGAIN, I AM DRIVING DOWN A HILL AND THE SAME THING HAPPENED. I WAS TOWING A VERY LARGE TRAILER THIS TIME AND THE EMERGENCY BRAKE HAD LITTLE AFFECT. LUCKILY, THERE WAS LITTLE TRAFFIC AND I WAS ABLE TO RIDE IT OUT WITHOUT INCIDENT. I HAVE SINCE DISCOVERED THAT THIS IS A PROBLEM WITH NOT ONLY THE 03 YEAR BUT 4 OR 5 YEARS PRIOR ALSO. ANOTHER MECHANIC TOLD ME THAT THE ENTIRE SYSTEM OF LINES SHOULD BE REPLACED SINCE GM USED A UNCOATED STEEL WHICH BEGINS TO BE COMPROMISED WITHIN JUST A FEW YEARS WHERE SALT IS HEAVILY USED IN THIS AREA. IT IS OBVIOUS THAT GM USED UNCOATED STEEL INSTEAD OF COATED OR STAINLESS TO SAVE A FEW DOLLARS. HAD MY 17 YEAR OLD SON BEEN DRIVING, THE OUTCOME COULD HAVE BEEN DISASTROUS. THIS IS ONLY ONE OF MANY PROBLEMS I HAVE HAD WITH THIS TRUCK. ANOTHER IS ERRONEOUS SPEEDOMETER READINGS. I WILL ADDRESS THESE IN ANOTHER POST. *TR

ISSUE WITH THROTTLE BODY REDUCED ENGINE POWER WHEN DRIVING THROWS OUT CHECK ENGINE LIGHT. THOUSAND OF PEOPLE HAVE THIS SAME ISSUE MOST HAVE JUST STOPPED DRIVING THEIR VEHICLE LIKE I HAVE BECAUSE IT'S UNSAFE TO DRIVE. I HOPING NOT JUST FOR ME BUT EVERYONE OUT THERE WITH THIS SAME ISSUE TO GET A RECALL BEFORE IT KILLS SOMEONE. I HAVEN'T BEEN ABLE TO DRIVE MY TRUCK IN THREE YEARS. *TR

I WAS DRIVING DOWN THE ROAD WHEN MY BRAKE PEDDLE WENT TO THE FLOOR, I HAD TO USE MY EMERGENCY BRAKE TO STOP MY VEHICLE. LUCKILY I SWERVED TO AVOID TRAFFIC IN FRONT OF ME AND WAS ABLE TO STOP SAFELY. UPON HAVING MY TRUCK TOWED, MY MECHANIC SHOWED ME THAT MY BRAKE LINE FROM MY MASTER CYLINDER HAD RUSTED OUT CAUSING BRAKE FAILURE. *TR

TL* THE CONTACT OWNS A 2003 GMC SIERRA 2500 HD. THE CONTACT STATED THAT WHILE TRAVELING VARIOUS SPEEDS, THE VEHICLE SUDDENLY STALLED. THE CONTACT ALSO MENTIONED THAT THE VEHICLE FAILED TO START. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT CONTACTED ABOUT THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 90,000.

I CROSS THE ROUTE 18 ON MASSACHUSETTS WHEN THE BRAKE IS COMPLETELY GONE ALMOST INVOLVED IN ACCIDENT. *TR

WHILE DRIVING, LARGE AMOUNT OF SMOKE CAME OUT. TOOK IT TO GM DEALER WHO SAID THAT IT THE FUEL INJECTORS WERE LEAKING. LOOKED ONLINE AND NOTICED HUNDREDS OF REPORTS OF THE SAME ACTION. GMC APPARENTLY DID AN EXTENDED WARRANTY FOR THE ISSUE, BUT ONLY COVERED IT FOR 7 YEARS FROM TIME OF PURCHASE AND UP TO 200,000 MILES. TALKED TO LOCAL DEALER WHO DENIED THE SERVICE AND GM WONT REPLACE THE FUEL INJECTORS. *TR

I HAD STOPPED AT A GAS STATION AND WHEN I LEFT I WAS GOING APPROXIMATELY 35 MILES PER HOUR WHEN I PUT PRESSURE ON THE BRAKES AND THE BRAKE LINES RUPTURED . WAS ABLE TO GET TO A REPAIR SHOP AND THEY SAID THAT THE LINES HAD RUSTED THROUGH. ALL LINES HAD TO BE CHANGED, *TR

2003 GMC SIERRA 2500HD THE INJECTORS WANT BAD WAS TOLD IT WAS THE FUEL HOUSING. SO CHANGED THAT NOW HAVING TO CHANGE INJECTORS. *TR

I KEEP GETTING REDUCED ENGINE POWER P1516 CODE . READING THE POST'S ON THE INTERNET THIS IS A REAL COMMON PROBLEM.ALSO THE SPEEDOMETER WILL DISPLAY 120 MPH SITTING AT A TRAFFIC LIGHT.
