Summary Verdict

The 2009 Hummer H3T presents a mixed reliability profile. The powertrain, particularly the 3.7L inline-5 engine, can experience cooling system and oil cooler line leaks, while the automatic transmission may develop shifting issues. Suspension components like ball joints and leaf springs are also noted for potential wear. Electrical gremlins, such as failing window regulators and sensor malfunctions, can occur. However, the exterior and interior generally hold up well, with no widespread critical failures reported. Owners should be mindful of the potential for leaks and transmission problems, budgeting for these repairs if they arise.
