2004 GMC Sierra Review

Classic good looks, powerful drivetrains, and lots of options.

Reviewed by Automotive on


It’s impossible to have any interest in full-size trucks and not be familiar with the GMC Sierra family of trucks. These trucks have been offered for many years and continue to be the mainstay of the working class. The Sierra often appears on farms, construction sites, and as delivery or small business vehicles. The 2004 GMC Sierra makes no exception. This truck comes in a variety of body styles and has a long list of standard equipment and options to choose from.

The Range

Body Styles: full-size pickup truck
Engines: 4.3-liter V-6, 4.8-liter V-8
Transmissions: five-speed manual, four-speed automatic
Models: GMC Sierra Work Truck, GMC Sierra, GMC Sierra SLE, GMC Sierra SLT, GMC Sierra Denali

What's New

For 2004, GMC makes several changes to the Sierra family of trucks. The Professional Package retires this year and the Quadrasteer Package drops the need for additional trailer equipment. All four-wheel-drive models come equipped with 17-inch wheels as well. On the base, chrome bumpers, grille, and wheels enhance the model, along with standard cruise control. The Work Package becomes available on all trim levels. Finally, the crew cab 1500 with a 5.5-foot bed joins the lineup to replace the 1500HD.


GMC offers an attractive and impressive line with the Sierra family. From the lower trim levels, up the Denali, these trucks look attractive in the classic GMC way with assertive front ends and dramatic grilles. The GMC logo sits obviously in the center of the grille. Depending on the trim level and body style chosen, the 2004 GMC Sierra features strong, clean lines down the body of the truck. Naturally, the larger extended cab and crew cab body styles look a bit different. GMC offers its Sierra trucks in a variety of color options, including Marine Blue Metallic, Sand Beige Metallic, and Polo Green Metallic just to name a few.


One of the biggest complaints about the 2004 GMC Sierra concerns the interior materials, some of which seem of poor quality. Even with that said the truck line comes well-equipped for the consumer and feels as comfortable as possible. In the base, the cloth seats split 40/20/40 and offer a decent amount of head and legroom. It also comes equipped with cruise control and air-conditioning. However, other comfort features remain relatively sparse.

For the SLE, things get a bit more luxurious. It uses the same front-seat design as the base, but it includes power accessories, cabin storage with the center console, and a leather steering wheel. For true comfort and luxury, GMC offers the Denali. This features leather bucket front seats with heating and height adjustment. A leather steering wheel with audio controls and a seven-speaker sound system come standard.

Performance & Handling

For the most part, the GMC Sierra has had a long reputation for reliability and performance. The 2004 GMC Sierra makes no exception. Equipped with powerful drivetrains and a solid suspension and braking system, this truck feels right at home working the farm, at the construction site, or on the highway. The impressive work capacity and performance rank among the traits that ensure the Sierra stays at the top of its class. It makes an excellent choice for anyone looking for a quality vehicle.


Safety features mark an important aspect of any vehicle and the Sierra series has several innovative standard features. Anti-lock brakes, a post-collision safety system, and child seat anchors comprise the list. The 2004 GMC Sierra also has an occupant-sensing airbag for the passenger seat that deactivates the airbag in the absence of a passenger.

EPA Fuel Economy

GMC Sierra 4.3 liter V-6: 14/19 mpg city/highway
