2003 Gmc Sierra 1500 problems
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.

I'm glad to hear that you found the perfect truck for you and your wife! After researching and test driving many trucks, the GMC stood out as the clear winner. It's great that the truck is easily accessible both inside and out. Although you experienced some minor issues, it's good to know that they were covered under warranty. While the fuel economy may not have been as good as you hoped, it's important to remember that you have a V8 engine and a towing package. Overall, it sounds like you're very happy with your purchase and even plan to upgrade to an extended cab in 2008.

This is a great truck! The ride is smooth and comfortable with great pick-up. My average fuel mileage is around 15 mpg...not real great. Turning radius is wide (watch out in those parking lots). Very nice interior with comfortable seats. Controls are easy to reach and intuitive.

Hi there! I wanted to share a bit about my vehicles with you. My first car was a 1966 Pontiac LeMans, which I still have to this day. However, I needed something with more hauling power, so I decided to get a truck. While the body styling on GMC's may not be as flashy as Chevy's or Ford's, I have been extremely pleased with my truck's performance. In fact, after adding a Hypertech power programmer to the engine, the output has been amazing! Although my gas mileage has dropped a bit to about 16/20, I don't mind it at all when I'm enjoying the performance. Thanks for listening!

Truck.........Nothing else that you could ask for! It handles great, drives like a car, but works like a truck.

I have been a loyal Ford man for 15 years. This time, I shopped around and found that there were great incentives available. The Sierra caught my attention with its solid build and quiet ride. The windnoise on Ford's trucks was the deciding factor for me. Although GMC is a great drive with a quiet ride, super performance, and great looks, I ultimately chose the Sierra. Best regards, A Ford Use To Be....

Although my experience with this vehicle has been less than satisfactory, I am confident in my assessment of its performance. Despite having only 8000 miles, it has required multiple repairs and has not met my expectations. The rattling, malfunctioning brake cylinder, faulty passenger window, and leaking rear axle seals are all issues that have negatively impacted my experience with this U.S. built auto. Based on my experience, I cannot recommend purchasing this vehicle.

The wind noise from the passenger side wing window is unacceptable. Despite three trips to the dealer and the replacement of the entire window, the issue persists.
