The 2008 HUMMER H3, a smaller sibling to the H2, offered a more approachable entry into the HUMMER brand. It's a mid-size SUV with distinctive HUMMER styling. Model years ran from 2006-2010. Key trims included the base H3, Adventure, and Luxury. Pricing ranged from around $30,000 new to $8,000-$15,000 used, depending on condition and mileage.

What Problems Does the 2008 HUMMER H3 Have?

Frequently reported problems with the 2008 HUMMER H3 include issues with the four-wheel-drive system, particularly the transfer case. Some owners have reported premature wear or failure of the transfer case. Electrical issues, such as problems with the window regulators, door locks, and the HVAC system, are also common. The ignition switch has been known to cause problems, leading to starting issues or the engine stalling.
Cooling system problems, including leaks from the radiator and water pump, have been reported. The 3.7L inline-five engine can suffer from head gasket failures and timing chain issues, leading to costly repairs. Rust is a concern, especially in areas with harsh winters and road salt usage. Check the undercarriage and body panels for rust.
While specific recalls may have been issued, it's crucial to check the NHTSA (National Highway Traffic Safety Administration) website for the most up-to-date recall information based on the vehicle's VIN. Long-term reliability can be a concern due to the age of these vehicles and the potential for deferred maintenance. Careful inspection and a thorough pre-purchase inspection are crucial before buying a used 2008 HUMMER H3.

How long will the 2008 HUMMER H3 last?

Given their age, many 2008 HUMMER H3s have accumulated significant mileage, often ranging from 150,000 to 250,000 miles or more. With diligent maintenance, some owners have reported reaching well over 200,000 miles. However, long-term durability is dependent on maintenance habits. Regular oil changes, fluid checks, and timely repairs are essential to extending the vehicle's lifespan. Weaknesses over time include potential for increased oil consumption, worn suspension components, and continued electrical gremlins. Rust is a significant long-term threat, especially in regions where road salt is used during the winter.

What Technology & Safety Features are Included?

The 2008 HUMMER H3's built-in tech and entertainment features were relatively basic for its time. Standard features included an AM/FM radio with a CD player and auxiliary input. Higher trims offered a premium sound system with a subwoofer. Navigation was an available option. Driver-assistance features were limited compared to modern vehicles. It included standard antilock brakes (ABS) and stability control.
Safety features included front and side airbags, as well as side curtain airbags for head protection. Optional features included OnStar for emergency assistance and remote door unlock. Crash-test ratings from the NHTSA (National Highway Traffic Safety Administration) and IIHS (Insurance Institute for Highway Safety) should be consulted for specific scores. Keep in mind that crash test standards and vehicle safety technology have advanced significantly since 2008. The H3 offered decent protection for its time, but lacks the advanced safety features found in newer SUVs, such as automatic emergency braking or lane departure warning.
While it lacked advanced technology, the HUMMER H3 focused on ruggedness and off-road capability rather than cutting-edge tech. The simplicity of the systems also made them less prone to failure than some more complex, feature-rich vehicles.

How Does the 2008 HUMMER H3 Compare to Other Sport Utility Vehicle?

The 2008 HUMMER H3 competed with mid-size SUVs like the Jeep Grand Cherokee, Toyota 4Runner, and Nissan Xterra. In terms of performance, the H3's base engine was often considered underpowered compared to rivals' offerings. The 4Runner offered superior reliability and resale value.

In terms of features, the H3 was generally comparable to its competitors, although some offered more advanced technology or comfort features.
