2003 Gmc Gmc truck problems
GMC (formerly the General Motors Truck Company (1911–1943), or the GMC Truck & Coach Division (1943–1998)) is a division of American automotive manufacturer General Motors (GM) for trucks and utility vehicles. GMC currently makes SUVs, pickup trucks, vans, and light-duty trucks. In the past, GMC also produced fire trucks, ambulances, heavy-duty trucks, military vehicles, motorhomes, transit buses, and medium duty trucks.
While many of their vehicles are mechanically similar, GMC is positioned as a premium offering to the mainstream Chevrolet brand, and includes the luxury trim Denali. In North America, GMC vehicles are almost always sold alongside Buick (another premium brand) vehicles at multi-brand dealerships.
History
Roots to the GMC brand can be traced to 1900, when the "Grabowsky Motor Company" was established by brothers Max (1874-1946) and Morris Grabowsky, in Detroit, and renamed Rapid Motor Vehicle Company in 1902 when the brothers moved operations to Pontiac, Michigan. In 1909, William C. Durant gained control of Rapid Motor Vehicle Company and made it a subsidiary of his General Motors Company.
In 1911, General Motors formed the "General Motors Truck Company" and folded Rapid and Reliance Motor Car Company (another early commercial vehicle manufacturer that Durant had acquired in 1908) into it. In 1912, the Rapid and Reliance names were dropped in favor of "GMC". All General Motors truck production was consolidated at the former Rapid Motor Plant 1 in Pontiac, Michigan.
GMC maintained three manufacturing locations in Pontiac, Michigan, Oakland, California, and St. Louis, Missouri .
In 1916, a GMC truck crossed the country from Seattle to New York City in thirty days, and in 1926, a 2-ton GMC truck was driven from New York to San Francisco in five days and 30 minutes. During the First World War, the company provided the Model 16 3/4-ton truck, and modified its production to provide 1-ton troop carriers and aviation support vehicles, and by 1918, more than 90 percent of GMC truck production was for military use. GMTC provided a total of 8512 trucks to the U.S. government during the war years and earned a Distinguished Service Award. During the Second World War, GMC Truck produced 600,000 trucks for use by the United States Armed Forces.
In 1923, GMC trucks were exported to Japan to help recovery and reconstruction as a result of the Great Kantō earthquake, and the company continued to provide vehicles as the transportation infrastructure was rebuilt. Before the earthquake struck, most of Japan's transportation of commerce and people was by wooden carts and government owned railroads, which were severely damaged when the train tracks were twisted beyond use. Autonomous trucks were much more effective at traveling to heavily damaged areas.
In 1925, GM purchased a controlling interest in Yellow Coach, a bus and taxicab manufacturer based in Chicago, Illinois which was founded by John D. Hertz. The company was renamed Yellow Truck & Coach Manufacturing Company (YT&CMC), an affiliated subsidiary of General Motors. All manufacturing operations of General Motors Truck Company were placed under YT&CMC. In 1928 Plant 2 opened and all headquarters staff moved to the administration building at 660 South Boulevard E in Pontiac, MI. In 1943, GM purchased the remaining interest in YT&CMC and renamed it GMC Truck and Coach Division.
In 1981, GMC Truck & Coach Division became part of GM Worldwide Truck & Bus Group. Bus production ended in May 1987 and the division name was changed from GMC Truck & Coach to GMC Truck Division. The Canadian plant (in London, Ontario) produced buses from 1962 until July 1987. GM withdrew from the bus and coach market because of increased competition in the late 1970s and 1980s. Rights to the RTS model were sold to Transportation Manufacturing Corporation, while Motor Coach Industries of Canada purchased the Classic design. In 1998, GMC's official branding on vehicles was shortened from "GMC Truck" to simply "GMC".
In 1996, GM merged GMC Truck Division with the Pontiac Motor Division in order to "give the combined division a brand image projecting physical power and outdoor activity". This coincided with many GMC dealerships merging with Pontiac dealerships, allowing a single dealer to offer both trucks and entry-to-mid-level cars, using a similar approach already in use by Chevrolet.
In 2002, GMC celebrated its 100th anniversary and released a book entitled GMC: The First 100 Years, a complete history of the company.
In 2007, GMC introduced the Acadia, a crossover SUV, which was the division's second unibody vehicle (after the Vandura) whose predecessor, the GMT-360 based Envoy, was discontinued with the closure of GM's Moraine, Ohio plant on December 23, 2008.
In 2009, GMC ended production of medium-duty commercial trucks after over 100 years. They became exclusive to Chevrolet with the launch of the 4500HD/5500HD Silverado in 2018. Also in 2009, GMC introduced the Terrain, a mid-size crossover SUV based on the GM Theta platform shared with the Chevrolet Equinox. It replaced the Pontiac Torrent after the brand's demise.
In 2020, General Motors announced the return of the Hummer nameplate, this time as a sub-brand of GMC instead of a stand-alone division. The Hummer lineup includes two models, an electric pickup truck and SUV, to be sold as the "GMC Hummer EV". According to GM, the Edition 1 production electric pickup truck will feature 1,000 horsepower, hit 60 mph in 3 seconds and is scheduled to launch in late 2021. The new Hummer EV was revealed on October 20, 2020.
In 2022, the GMC brand was introduced in South Korea as a subsidiary of GM Korea.

- Summary: BRAKE LINES, TRANSMISSION LINES AND ENGINE COOLANT LINES ALL FAILING ON 2003 GMC 2500 HD SIERRA AS WELL AS ON 2004 CHEVY SILVERADO HD 3500. THESE PROBLEMS HAVE CAUSED NUMEROUS AMOUNTS OF TIME TO REPAIR AND REPLACE, AND TODAY THERE WAS A CATASTROPHIC BRAKE FAILURE ON THE 2003 HD GMC WHICH ALMOST RESULTED IN A DEADLY ACCIDENT. THESE LINES SHOULD NOT HAVE RUSTED THEY WAY THEY ARE ESPECIALLY ON TWO (2) DIFFERENT VEHICLES FROM THE SAME MANUFACTURER. THESE VEHICLES WERE PRODUCED WITH INADEQUATE PARTS FOR ALL LINES ON THE UNDERSIDE OF VEHICLE. THERE SHOULD NOT BE 1,000 PLUS COMPLAINTS FROM CONSUMERS REGARDING THE RUSTING OF THESE COMPONENTS, OF WHICH HAVE CAUSED SEVERAL MAJOR AND LIFE SAFETY ISSUES. THE BRAKE LINES ARE AN INTEGRAL PART OF ANY VEHICLE AND TO HAVE THEM RUST THRU TO THE DEGREE OF ALL THE COMPLAINTS THERE IS OBVIOUSLY AN ISSUE WITH THE COMPONENT THE MANUFACTURER INSTALLED ON THESE VEHICLES. BETWEEN OUR 2003 AND 2004 GMC AND CHEVY TRUCKS RESPECTIVELY, WE HAVE REPLACED ALL OF THE TRANSMISSION COOLANT LINES IN BOTH VEHICLES, OIL ENGINE LINE IN 1 VEHICLE, READY TO CHANGE IN OTHER VEHICLE DUE TO RUST, AND NOW BRAKE LINES IN THE 2003 AND WILL NEED TO REPLACE IN 2004 DUE TO RUST AS WELL. THE ENTIRE UNDERSIDE COMPONENTS ARE COMPLETELY RUSTED THROUGH. IN ADDITION, THE STRAPS THAT HOLD THE FUEL TANK ARE ALSO NEEDING TO BE REPLACED DUE TO RUST. *TR

THE SPEEDOMETER REGISTER ERRATICALLY AND SOMETIMES STAYS ON 0 MPH WHILE DRIVING DOWN THE HIGHWAY. I HERE THE FUEL GAUGE IS NEXT TO GO BAD. THESE TWO PROBLEMS TOGETHER ON A BUSY HIGHWAY CAN AND WILL CAUSE ACCIDENTS WHERE SOMEONE WILL GET HURT OR KILLED. GM HAS AGREED TO RECALL THESE VEHICLES WITH UNDER 70,000 MILES AND 5 YRS. OLD. THIS DOES NOTHING TO THIS SAFETY PROBLEM BUT LOWER THE ODDS A LITTLE BIT. WHAT ABOUT THE SAFETY OF THE BALANCE OF OWNERS OF THE REMAINING VEHICLES AND EVERY PERSON ON US HIGHWAYS? DOESN'T ANYONE CARE? PLEASE LOOK INTO THIS SAFETY PROBLEM FOR IT HAPPENS ALL OF THE SUDDEN. THIS FAILURE HAPPENS AND THEN IT WORKS FINE OFF AND ON OR IT JUST TOTALLY FAILS ALL AT ONCE. YOU HAVE NO IDEA HOW FAST YOU ARE DRIVING WHICH AFFECTS PUBLIC SAFETY AND RUNNING OUT OF FUEL ON A SNOW COVERED OR DRY FREEWAY OR RTE. AND NOT BEING ABLE TO STEER THE TRUCK CAN DEFINITELY CAUSE ACCIDENTS. PEOPLE HAVE NO CLUE WHEN OR WHERE THESE PROBLEMS WILL OCCUR. I HOPE THAT YOU ARE ALSO CONCERNED ABOUT THE VEHICLES WITH THIS PROBLEM ON THE ROADS WITH MORE THAN 70,000 MILES AND OLDER THAN 5YEARS. I AM A CERTIFIED AUTOMOTIVE MECHANIC AND HAVE BEEN FOR 30 YEARS. WHAT SCARES ME IS THE OLDER THE VEHICLE THE MORE CHANCE OF HYDRAULIC BRAKE LINES FAILING FROM RUST AND NOT KNOWING IF THEY ARE DRIVING TOO FAST FOR CONDITIONS WITH A BRAKE LINE FAILURE IS GOING TO HAPPEN IF NOT ALREADY. PLEASE PROTECT EVERYONE AND YOURSELF FROM GENERAL MOTORS CORPORATION'S SHOTTY RECALL. *TR

- VIN: 2GTEC19V131
- Components: ELECTRICAL SYSTEM
- Summary: SPEEDOMETER FAILURE IN 2003 GMC SIERRA, I FEEL THAT THIS TYPE OF FAILURE SHOULD BE CONSIDERED A SAFTEY DEFECT AND BE COVERED BY THE GM CORP. I HAVE BEEN FIGHTING WITH THE CORP FOR THE PAST THREE MONTHS TO COVER THIS IT WAS A DEFECTIVE STEPPER MOTOR IN ALL THE INSTRUMENT CLUSTERS AND THE PART NUMBER WAS XC5-168 THE NEW PART NUMBER IS X25-168 WHY WAS THIS NEVER CONSIDERED A SAFTEY RECALL, IS THE SPEEDOMETER NOT CONSIDERED PART OF THE SAFETY RECALLS ON OUR ROADWAYS? THE FACT THAT I CAN DRIVE DOWN THE HIGHWAY AT "ACCORDING TO MY SPEEDOMETER" AT 120 MPH AND CARS ARE PASSING ME, OR THE FACT THAT I MIGHT BE DOING ONLY 30MPH IN THE SAME SITUATION, IS THIS NOT CONSIDERED PART OF A SAFTEY RECALL? IT IS AND HAS BEEN KNOWN THAT THESE STEPPERS MOTORS IN THE INSTRUMENT CLUSTERS HAS BEEN BAD, AND NOT THE FAULT OF ANY DRIVER BUT THE FAULT OF THE GM CORP., DO WE HAVE TO WAIT UNTIL SOMEONE IS KILLED BY SOMETHING LIKE THIS THINKING THAT THER ONLY DOING 30MPH BUT IN FACT ARE RUNNING DOWN THE ROAD AT 80MPH.... SURE THE MORE EXPERIENCED DRIVER MIGHT KNOW THE DIFFERENCEBUT WHAT ABOUT THE LESS EXPERIENCED, LIKE YOUR CHILD? I WOULD NEVER WANT THIS TO HAPPEN, AND YOU HAVE TO ADMIT THAT IT COULD, SOMETHING SHOULD BE DONE ABOUT THIS... A SAFTEY RECALL, NOT JUST SOME SERVICE BULLETIN, THAT THE DEALER MAILS TO SOME OF THE OWNERS, IF IN FACT THEY HAVE THE NAME ON FILE, SOMEONE COULD HAVE BOUGHT THIS USED FOR THIER CHILD.

THE FAILURE OCCURRED ONE YEAR AFTER THE VEHICLE WAS PURCHASED. THE RACK AND PINION HAS BEEN REPLACED FIVE TIMES. THE BEARINGS AND SHOCKS HAVE ALSO BEEN REPLACED. OVER ONE YEAR LATER, THE FAILURE HAS RECURRED. THE DEALER HAS MADE NINE UNSUCCESSFUL ATTEMPTS TO DIAGNOSE THE CAUSE OF FAILURE. GM STATED THAT THE FAILURE COULD BE RELATED TO THE STEERING GEARS AND ADVISED THE DEALER TO REPLACE THEM INSTEAD OF LOOPING THE GEARS. THE MANUFACTURER ALSO AUTHORIZED THE DEALER TO REPLACE THE SHOCK AND SPRING MOUNTS. THERE WAS AN ATTEMPT TO REPAIR THE BEARING GEAR INSIDE THE RACK AND PINION, BUT THE FAILURE CONTINUED. THE VIN AND FUEL SYSTEM WERE UNAVAILABLE. THE CONTACT HAS COPIES OF THE RELATED INVOICES. THE CURRENT MILEAGE IS 33,000 AND FAILURE MILEAGE WAS 12,000.

SOMETIMES IT FLUCTUATES BETWEEN 70 AND 120 + BUT IT IS NEVER CORRECT. THIS SEEMS LIKE A HUGE SAFETY ISSUE AND IT APPEARS FROM READING ONLINE THAT THERE ARE TONS OF OTHER PEOPLE OUT THERE WITH THE SAME PROBLEM. THIS SEEMS LIKE SOMETHING THA GMC SHOULD FIX FOR FREE CONSIDERING THE SAFETY ISSUES. WE DONT HAVE THE MONEY TO SPEND ON SOMETHING THAT IS OBVIOUSLY THE MANUFACUTRERS FAULT.

POWER TRAIN PROBLEM
- Date Of Incident: 2005-11-17
- VIN: 2GTEK19V631
- Components: POWER TRAIN
- Summary: LOUD CLUNK IN DRIVETRAIN WHEN TRANSMISSION UPSHIFTS 2-3 AND DOWNSHIFTS 3-2. VEHICLE IS 2003 GMC PICK-UP TRUCK 4X4. DEALER #1 REPLACED DRIVESHAFT. NO CHANGE. DEALER #2 DIAGNOSED THE CLUNK AS A MOMENTARY TORQUE REVERSAL OF THE OUTPUT SHAFT WHEN THE CLUTCH IS APPLIED AND THE 2-4 BAND RELEASED. SEE GM INFORMATION BULLETIN #01-07-30-042C (SEPT. 27, 2005) GM SAYS THIS IS NORMAL AND NO REPAIRS SHOULD BE ATTEMPTED. THIS CONSTANT CLUNKING IS NOT NORMAL AND IS AGGRAVATING TO THE DRIVER AND OWNER. A NEW VEHICLE SHOULD BE FREE OF MECHANICAL DEFECT AS THE WARRANTY STATES. THIS CONDITION MAY BE WORSE IN 4X4 VEHICLES DUE TO TOLERANCES IN THE TRANSFER CASE. GM WILL NOT RECTIFY THIS DEFECT WHILE UNDER ORIGINAL WARRANTY. IT IS THEIR DUTY TO SELL A DEFECT FREE VEHICLE. I HAVE DISCUSSED THIS PROBLEM WITH GM, BBB, A TRUCK DEALER AND A TRANSMISSION REPAIR SHOP. MY CONCLUSION IS THAT A REPROGRAMMING OF THE BANDS IN THE TRANSMISSION CASE WILL CORRECT THIS DEFECT. GM IS NOT WILLING TO MAKE THIS REMEDY AVAILABLE TO THE VEHICLE. MY EXPECTATION IS THAT THE VEHICLE SHOULD BE DEFECT FREE DURING WARRANTY PERIOD. THE STANDOFF! THE FEDERAL GOVERNMENT SHOULD PROTECT THE UNWITTING BUYER FROM THE FAILURES OF AUTO MAKERS TO WARRANT A DEFECT FREE PRODUCT AS THEY CLAIM WHEN THEY SELL THE PRODUCT. OTHERWISE, IT IS A GROSS MISREPRESENTATION OF A PROMISE AND FRAUD. *JB

I TOOK IT TO MY LOCAL GM DEALER AND THEY INFORMED ME THE FAN CLUTCH HAD FAILED AND REPAIRED IT FOR OVER 700$. UPON RESEARCH LATER ON THIS PART I NOTICED PEOPLE SAYING THESE ARE FAILING AT A REGULAR BASIS. NOW, I'M NOT A MECHANIC, BUT I THINK HAD I NOT THE KNOWLEDGE I DO OF AUTOMOBILES, I WOULD HAVE CONTINUED TO DRIVE AND POSSIBLY COULD HAVE HAD A MAJOR ENGINE FAILURE OF SOME SORTS. THIS COULD HAVE RESULTED IN A SERIOUS INCIDENT ON THE ROADS. MY VEHICLE HAD ONLY 40,000 MILES ON IT. NOT MANY, CONSIDERING THE IMPORTANT OF OPERATION OF THIS PART. *NM
