2003 Chevrolet Silverado 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.

Is a 2003 Chevy Silverado a good truck?
A solid mix of everyday comfort and sheer towing power. The 2003 Chevrolet Silverado is a roomy, capable full-size truck. If you can't find one with low mileage, the truck is definitely showing its age with expensive repairs piling up. The unwieldy cornering makes it a poor choice for city driving.

At 170,000 miles now, this truck runs like new. The 4.8 motor has plenty of power and still gets upwards of 22mpg, although it doesn't do as well in town driving (maybe 14-15 mpg). But compared to other full-size trucks that don't get as good mpg and some have less power, this truck is unbeatable.

You now have 185,000 miles on your truck and you pull a small trailer for work with no problems. It's normal for parts like starters, plugs, wires, tires, and brakes to need replacement, but overall it's a great truck!

Congratulations on your 4th Silverado! It's wonderful to hear that you love everything about it, from the Bose sound and 6-disc in-dash stereo to the comfortable interior. It's impressive that even with 106k miles on it, you haven't had any problems. Although you mentioned a minor issue with the face of the radio, it's great to know that the truck holds its value really well. Thank you for sharing your positive experience with us!

Hi there! I just wanted to share my experience with my truck. I bought it used with 69,000 miles 2.5 years ago and I've put on 115,000 miles since then. The best part? I haven't had any problems with it! I regularly tow a 3000 lb ski boat and have a truck camper in the bed and the 5.3 L has no problem handling it. It's been a reliable companion for all my adventures!

At 308,000 miles it still runs like new. I'm the 3rd owner. The previous owner did not service it, ran it hard, beat it up, and never got an oil change in the 5 years they owned it. Despite all that, it still runs great!

Real bad build quality. The brakes are horrible - expect to replace all rotors and pads especially the back every 20,000 miles. Items replaced under warrenty: Steering column (twice); passenger window motor + track; heater element. Here is what went after warrenty: anti-lock brake sensor (40,000 miles) ~ $250; water pump (48,000 miles) ~ $450; the steering column that was replaced twice is cluncking again. Numerous other defects too small to mention. This truck is literally garbage.

I bought my 03 2wd extended 4.8l ls in 07, so it's 15 years old now and has over 190,000 miles. Despite its age, it still runs great with no problems with the engine. The ride is pretty good, but unfortunately, these GMs are known for electrical problems. The instrument panel cluster has been repaired twice, but it still won't act right and drains the battery if I let the truck sit for a day or longer. It's a pain in the neck, so I just disconnect the whole thing and use my phone for my mph. I've had the water pump replaced, and it's rusting on the rocker panels. The engine does cut off on me mostly when I'm slowing down and making a turn. The wheel caps are a pain too. They're hard to put on, and they get loose after some time. I've lost 3-4 of these so far. I've replaced both power window motors, but all in all, it hasn't failed me hard, and nothing major has gone wrong. For its age, it's reliable, but nothing close to a Toyota, haha! Would I buy it again? Well, I'd get the older models from 90-98. I've heard they're built better.

4000 miles and minor problems. Both rear windows and seals have been replaced due to poor design with wind noise. The vibration/buzz in the gas pedal is currently being worked on, but I know there is a TSB from GM on this. This truck is really fun to drive, it's smooth and has plenty of power from the reliable 4.3L engine. My wife loves the room and the feel of a truck in the city.

I've had the pleasure of owning 6 Chevrolet pickups over the years, an 81, 83, 84, 87, 95, and 98. They were all great trucks that took a beating from me and kept on going. However, my seventh pickup, a 2003 Z71, has been a bit of a disappointment. While it had only 40000 miles when I bought it, I've already had to replace both front wheel bearings, the brakes (rear twice), transmission, two alignments, instrument panel cluster, radio, tie rods, and now it has a growling sound that drives me crazy. I'm a bit hesitant to push it too hard, as it doesn't seem as sturdy as my previous trucks. I'm disappointed to say that this will be the last GM vehicle that I will ever buy!

As a contractor, you've worked this truck hard, towing and hauling with it, and it has never let you down. It's comfortable, has a good ride, and nice features. Like all GM trucks of this era, the speedometer leaves a lot to be desired, but with 170,000 miles on it, it's still rock solid.
