2007 Hummer H2 problems
The Hummer H2 is an full-size off-road sport utility vehicle (SUV) that was marketed by Hummer and built in the AM General facility under contract from General Motors from 2002 until 2009. It is based on a modified GMT820 GM three-quarter-ton pickup truck in the front and a half-ton 1500 frame in the rear. A four-door pickup truck version with a midgate that opens the vehicle's interior to the external cargo bed was introduced for the 2005 model year as the H2 SUT (sport utility truck).
Background
In 2001 and 2002, GM allowed journalists to examine early versions of the Hummer H2, which were still under development at the time.
The H2 was built by AM General under contract with General Motors at AM General Commercial Assembly Plant in Mishawaka, Indiana.

Common 2007 Hummer H2 problems
The Hummer H2, a symbol of American vehicular excess, is known for its reliability and off-road capabilities. However, as with any vehicle, it can develop certain problems over time. Here are some of the most common issues reported by Hummer H2 owners:
- Gas cap issues: Many 2003-2009 Hummer H2 owners have reported problems with loose or worn gas caps. This issue can cause the check engine light to illuminate. While a gas cap problem is one possible cause, there are other issues that can trigger the check engine light, so it's best to consult a mechanic for proper diagnosis.
- Low oil pressure: Problems with oil pressure were among the top complaints for the 2006 model year. Repairs for this type of problem can reach up to $7,000. Many 2006 Hummer H2 owners reported loud knocking sounds along with coolant loss. In most cases, replacing the oil pump did not solve the issue, and some drivers had to replace their engines entirely.
- Engine stalling and low idle speed: Some 2003-2006 Hummer H2 owners have complained that their SUV is prone to engine stalling and low idle speed. Servicing the throttle body usually corrects the issue. Throttle body cleaning typically costs between $230 and $290. It's important to note that many underlying issues can cause the H2 to stall, so it's best to consult a mechanic for proper diagnosis.
These are some of the most common problems reported by Hummer H2 owners. To address these issues, it's crucial to consult a mechanic and consider the costs and potential solutions for each problem.
