2003 Gmc Sierra 2500 problems

gmc logo

The Chevrolet Silverado is a range of trucks manufactured by General Motors under the Chevrolet brand. Introduced for the 1999 model year, the Silverado is the successor to the long-running Chevrolet C/K model line. Taking its name from the top trim level from the Chevrolet C/K series, the Silverado is offered as a series of full-size pickup trucks, chassis cab trucks, and medium-duty trucks. The fourth generation of the model line was introduced for the 2019 model year.

The Chevrolet Silverado shares mechanical commonality with the identically related GMC Sierra; GMC ended the use of the C/K nomenclature a model generation prior to Chevrolet. In Mexico, high-trim level versions of the Silverado use the Chevrolet Cheyenne name (not to be confused with the 2003 concept). Competing against the Ford F-Series, Ram Pickup, Toyota Tundra, and Nissan Titan, the Silverado is among the best-selling vehicles in the United States, having sold over 12 million trucks since its introduction in 1998 as a 1999 model year.

History

The Silverado nameplate made its debut for the 1975 model year, becoming the top trim level on all Chevrolet C/K trucks, slotted above Custom Deluxe, Scottsdale, and Cheyenne. For the 1968 model year (seven years before the Silverado), GMC C/K trucks used variations of the Sierra name (Sierra, Sierra Classic, Sierra Grande, and High Sierra). Even after the C/K series officially ended, GM still uses the CK and the CC in their current model codes, to denote a two-wheel drive (CC), and four-wheel drive (CK).

For the 1988 GMT400 model architecture, Chevrolet retained the C/K model nomenclature, with GMC branding its full-size line as Sierras. While sharing the same body and chassis, the model chronology of the Silverado and Sierra are different, with five generations of the Sierra, while four of the Silverado.

In 2018, at the NTEA Work Truck Show in Indianapolis, Indiana, Chevrolet unveiled the first medium-duty Silverado, expanding the model line to a 4500HD, 5500HD, and 6500HD chassis cab. Largely the successor to the 2003–2009 GMT560 chassis, the medium-duty trucks are exclusive to Chevrolet, with no plans for an equivalent GMC version. Instead, Navistar International (now partnering with GM) would sell the medium-duty trucks as a rebadged counterpart, called the CV. This is in fact a very similar nod to how the Avalanche did not have a GMC Yukon–based equivalent, but instead, Cadillac would take its place as the former's rebadged counterpart, the Escalade EXT.

Negative 2003 Gmc Sierra 2500 car reviews

  1. Desmond Wilkinson 2024-04-18

    This GMC may not be the flashiest ride, but it's got some power under the hood with a 6.0 liter engine and 4.10 rear end. While it may not be the most fuel efficient, averaging around 14 mpg, it has the potential to get up to 15 mpg on a flat highway. There have been a few minor issues, such as a jerky transmission, radio failure, rattle in the steering shaft, center console latch, and noisy heater fan, but overall, I'm pretty satisfied with my purchase and hoping for a long run.

Positive 2003 Gmc Sierra 2500 car reviews

  1. Florian Kilback 2024-09-07

    Overall, I'm pleased with the standard duty 2500. The truck seems to ride and handle much better than the 2500HD if you don't need the extra capacity.

  2. Jairo Moore 2024-09-05

    I haven't logged too many miles yet (about 1000), but my first impression is that this truck meets high quality standards. I haven't found anything that needs tightening, fixing, or changing, and I've looked under, inside, and around this vehicle.

  3. Triston Bashirian 2024-08-01

    Lately, I've been experiencing an issue where the 4WD light comes on intermittently. Unfortunately, the troubleshooting procedures from the Chilton manual didn't help much, and I ended up replacing the front diff actuator motor unnecessarily. After some investigation, it turns out that the real culprit is a sticky selector switch. It seems that humidity may be affecting this switch, causing the resistors to fail for each position and lose the ability to keep a voltage signal to the transfer case module. On the bright side, the original battery lasted an impressive 6 years! Additionally, I discovered a leak at the front differential. At first, I thought it was the output seal, but it ended up being the plastic vent cap that screws into the diff.

  4. Hadley Tremblay 2024-07-22

    Great truck! You've put 180,000 hard, heavy towing miles on it with very few problems. It's a 6.0 5-speed, 4x4, right?
