Hummer H3 sut problems
The Hummer H3 is an off-road vehicle that was produced from 2005 to 2010 by General Motors. The smallest model of the Hummer lineup, it was offered as a 5-door SUV or a 4-door pickup truck known as the H3T. Unlike the larger H1 and H2 models, the H3 was not developed by AM General. It was introduced for the 2006 model year, based on a modified GMT355 that underpinned the Chevrolet Colorado/GMC Canyon compact pickup trucks that were also built at GM's Shreveport Operations in Shreveport, Louisiana and the Port Elizabeth plant in South Africa. While mechanically related to the Colorado and Canyon, GM claims they share only 10% of their components, with the chassis modified and reinforced for heavy off-road duties.
Powertrains
The H3 was launched with a 3.5 liter straight-5 cylinder L52 engine that produced 220 hp (160 kW) and 225 lbf⋅ft (305 N⋅m) of torque and was mated to a standard five-speed Aisin AR5 manual transmission or an optional Hydra-Matic 4L60-E four-speed automatic transmission. In 2007 this engine was replaced by the 3.7 liter LLR that produced 242 hp (180 kW) and 242 lbf⋅ft (328 N⋅m) of torque, figures that were revised in 2009 to 239 hp (178 kW) and 241 lbf⋅ft (327 N⋅m). Under revised EPA testing standards when equipped with either transmission this straight-5 engine achieved 14 mpg‑US (17 L/100 km) in the city and 18 mpg‑US (13 L/100 km) on the highway with a combined average of 15 mpg‑US (16 L/100 km).
Available solely with the 4L60-E automatic transmission, a 5.3 liter LH8 V8 engine producing 300 hp (224 kW) and 320 lbf⋅ft (434 N⋅m) of torque was added in 2008 for the Alpha model. The V8 version had lower fuel economy, estimated at 13 mpg‑US (18 L/100 km) in the city, 16 mpg‑US (15 L/100 km) on the highway, with a combined average of 14 mpg‑US (17 L/100 km).
In 2007, a H3X edition was added. It included the luxury package, 18-inch chrome wheels with unique center caps, chrome trim, chrome tube steps, a body-colored grille and a hard tire cover. The H3X also came with exclusive colors of Sonoma Red Metallic or Desert Orange Metallic.

Common Hummer H3 sut problems
Based on the complaints from owners of the Hummer H3 SUT cars, several common problems have been reported:
- Oil Light Illumination: Some owners have reported the oil light coming on, particularly after the engine has warmed up. The light tends to illuminate when coming to a complete stop and accelerating again, indicating potential low oil pressure. Despite regular oil checks and maintenance, the issue persists, leading to speculation about faulty sensors or the oil pump.
- Engine Stalling and Low Idle Speed: Another common problem reported by owners is engine stalling and low idle speed, especially in older models of the Hummer H3. This issue has been linked to throttle body problems, requiring servicing that can cost a few hundred dollars.
- Mode Door Actuator Failure: For 2003-2009 Hummer H2s, mode door actuator failure has been a widely reported issue. This problem can lead to HVAC temperature and air delivery issues, requiring diagnosis and repair that can cost owners around $50 to $70.
- Gas Cap Issues: Owners have also faced complaints related to loose or worn gas caps in the 2003-2009 Hummer H2 models. This issue often triggers the check engine light, necessitating a visit to the mechanic for proper diagnosis and potential replacement of the gas cap.
- Oil Pressure Problems: In some 2006 Hummer H2 models, oil pressure problems have been prevalent, with loud knocking sounds and coolant loss reported by owners. Repairs for this issue can be costly, sometimes requiring the replacement of the oil pump or even the engine in severe cases.
These common problems with the Hummer H3 SUT cars highlight the need for owners to be vigilant about maintenance and prompt repairs to ensure the longevity and performance of their vehicles.
