What Problems Does the 2004 GMC Sierra 2500HD Have?
The 2004 GMC Sierra 2500HD has several frequently reported problems. One prominent issue revolves around the Duramax diesel engine (LB7). Injector failures are common and costly to repair. Symptoms include rough idling, white smoke, and decreased fuel economy. Another frequently reported problem is with the fuel sending unit, leading to inaccurate fuel gauge readings. Transfer case issues, particularly in 4x4 models, are also reported. These can range from difficulty shifting to complete failure. Rust is a significant long-term reliability concern, especially in areas with salted roads. Check the rocker panels, cab corners, and frame for rust. Recalls for the 2004 model year included issues related to the fuel tank and possible steering shaft separation. Long-term, the electrical system can experience problems due to corrosion and aging wiring. Regular maintenance, especially fluid changes and inspection of suspension components, is crucial to mitigate potential issues and extend the truck's lifespan. The 2001-2004 LB7 Duramax engine is particularly known for injector problems, making careful inspection and maintenance records essential when considering a used model.
How long will the 2004 GMC Sierra 2500HD last?
With proper maintenance, a 2004 GMC Sierra 2500HD can easily exceed 200,000 miles or 20+ years of service. However, longevity heavily depends on maintenance habits. Neglecting fluid changes, ignoring warning signs, and infrequent servicing will significantly shorten its lifespan. Long-term durability is generally good, but weaknesses include rust, especially in colder climates, and the aforementioned issues with the Duramax diesel's fuel injectors. Front-end components (ball joints, tie rod ends) are also prone to wear due to the truck's weight and heavy use. Regular lubrication and inspection are crucial. Well-maintained models regularly see 250,000 miles or more.
What Technology & Safety Features are Included?
The 2004 GMC Sierra 2500HD offered relatively basic tech and safety features by today's standards. Standard features included a basic AM/FM radio, and optional features included a CD player, cassette player, and upgraded sound systems like a Bose system on higher trims. Driver-assistance features were limited; ABS was standard, but features like traction control were optional.
Entertainment options focused on audio quality and included available features such as:
In terms of safety, the 2004 Sierra 2500HD came standard with front airbags and antilock brakes (ABS). Driver-assistance features were sparse compared to modern vehicles. Electronic Stability Control (StabiliTrak) was available on some models. Crash test ratings from the NHTSA (National Highway Traffic Safety Administration) varied depending on the cab configuration. Some cab styles received 4-star ratings for frontal impact protection. Side impact testing was not as comprehensive. It's important to note that safety technology has advanced significantly since 2004, so this truck lacks many of the modern driver-assistance and safety features found in newer vehicles. Optional features included power windows, power locks, and keyless entry. The SLT trim offered features like automatic climate control and leather seats.

2004 GMC Sierra 2500HD Prices and Market Value
When new, the 2004 GMC Sierra 2500HD ranged from approximately $25,000 to $40,000 depending on the cab configuration, trim level, engine, and options. Currently, used market prices range from approximately $8,000 to $20,000+, depending on condition, mileage, and location. Depreciation has been significant, but the truck's inherent value as a work vehicle keeps prices relatively stable compared to other vehicles of the same age. Resale value is affected by factors such as engine (Duramax diesels command a premium), 4x4 capability, low mileage, clean title, and absence of rust. Well-maintained examples fetch higher prices. Trucks with documented maintenance history and desirable options also hold their value better.
2004 GMC Sierra 2500HD Cost of Ownership
The 2004 GMC Sierra 2500HD is not particularly economical to own. Insurance costs are moderate, but fuel costs are high, especially with the gas engines. Maintenance and repair costs can be significant, particularly for the Duramax diesel due to potential injector issues. Long-term ownership costs are higher than those of a smaller, more fuel-efficient vehicle. Regular maintenance, including fluid changes and inspections, is crucial to minimize expensive repairs. Rust prevention is also important. Overall, expect higher than average ownership costs.
