What Problems Does the 2004 GMC Sierra Have?
Frequently reported problems for the 2004 GMC Sierra include transmission issues, particularly slippage or hard shifting, especially in models with higher mileage. Rust is a significant concern, particularly in areas where road salt is used, affecting body panels, frame, and brake lines. Electrical problems, such as malfunctioning gauges, power windows, and door locks, are also common. HVAC issues, including blower motor failure and problems with the temperature controls, are frequently reported. There were some recalls issued for the 2004 GMC Sierra, including issues related to the fuel system, airbags, and brake lights. Check the NHTSA website for a complete list of recalls by VIN. Long-term reliability can be affected by the issues mentioned above, particularly rust and transmission problems. Proper maintenance and addressing problems promptly can help mitigate these concerns. The earlier years of this generation (1999-2002) experienced some issues which were addressed in later models, but it's still important to inspect any used 2004 Sierra thoroughly before purchasing.
How long will the 2004 GMC Sierra last?
With proper maintenance, a 2004 GMC Sierra can easily exceed 200,000 miles or more. Many owners report reaching 250,000 to 300,000 miles with regular servicing. Maintenance habits play a crucial role; consistent oil changes, transmission fluid flushes, and addressing repairs promptly are essential. Long-term durability can be affected by rust, as mentioned earlier. Transmission issues also tend to emerge over time. Weaknesses include potential for wear and tear on suspension components and the aforementioned electrical gremlins. Careful ownership and preventative maintenance are vital for long service life.
What Technology & Safety Features are Included?
The 2004 GMC Sierra's built-in tech and entertainment features are relatively basic by today's standards. Standard features typically included an AM/FM radio with a cassette player, and optionally a CD player. Higher trims offered features like a Bose premium sound system. Driver-assistance features were limited; options included cruise control and daytime running lights. Safety features included standard airbags, anti-lock brakes (ABS), and optional traction control. There were no advanced driver-assistance systems (ADAS) like lane departure warning or blind-spot monitoring available.
Crash-test ratings from the NHTSA varied depending on the cab configuration. Extended cab models received lower ratings than regular cab models in some tests. The IIHS (Insurance Institute for Highway Safety) ratings should also be consulted if available, although their testing methodologies have evolved over time. Keep in mind that safety technology has significantly advanced since 2004, so these vehicles offer a lower level of protection compared to modern vehicles. Optional features also included OnStar, which provided emergency assistance and vehicle diagnostics, a significant feature for its time. Stability control was not widely available on this model year.

2004 GMC Sierra Prices and Market Value
When new, the 2004 GMC Sierra ranged in price from approximately $20,000 to $40,000, depending on the trim level, cab configuration, and options. Current used market prices vary widely based on condition, mileage, and location. Expect to find them ranging from $5,000 to $15,000, or even lower for high-mileage or poorly maintained examples.
Depreciation has been significant, as with most vehicles of this age. Factors affecting resale value include the truck's overall condition (rust is a major detractor), mileage, engine type, drivetrain (4WD models typically command higher prices), and trim level. Well-maintained examples with lower mileage and desirable options (like leather seats or a tow package) will fetch the highest prices.

2004 GMC Sierra Cost of Ownership
Insurance costs for a 2004 GMC Sierra are generally moderate, varying based on driving record and coverage levels. Fuel costs can be significant, especially with the V8 engines, due to their relatively poor fuel economy. Maintenance costs are moderate, with readily available parts.

How Does the 2004 GMC Sierra Compare to Other Truck?
The 2004 GMC Sierra's key rivals included the Ford F-150, Dodge Ram 1500, and Chevrolet Silverado (its GM twin). In terms of performance, the Sierra's V8 engines were competitive with those offered by Ford and Dodge. Feature-wise, it was generally on par, although some competitors might have offered slightly different option packages. Reliability is a mixed bag; the Sierra has a similar reliability record to the Silverado, but the F-150 and Ram 1500 had their own sets of issues. Price-wise, the Sierra was typically similar to the Silverado and F-150.
Alternatives to the 2004 GMC Sierra include the 2004 Chevrolet Silverado (virtually identical mechanically, so it comes down to styling preference). The 2004 Ford F-150 offered a more modern interior design and, depending on the engine, similar performance. The Dodge Ram 1500 might be considered if styling is a priority. If reliability is paramount, consider a Toyota Tundra of similar vintage, although it might be more expensive to purchase. The Nissan Titan is another option, offering robust performance, but parts and service might not be as readily available.

Final Verdict: Is the 2004 GMC Sierra a Good Truck?
The 2004 GMC Sierra is ideal for someone seeking a capable and relatively affordable used truck for work or occasional hauling/towing. It's worth buying if you can find a well-maintained example with documented service history and minimal rust. Avoid trucks with obvious signs of neglect or transmission issues. Look for SLE or SLT trims for enhanced comfort features. Given its age, buying a 2004 Sierra is strictly a used proposition. It's a decent option for budget-conscious buyers who need a truck, but be prepared for potential maintenance and repair costs. Have it inspected by a trusted mechanic before committing to a purchase. A 4WD model is preferable if you live in an area with snow or require off-road capability.
