Common Hummer H2 sut problems
The Hummer H2 is known for its unique design and powerful performance, but it also has several common problems that owners often report. Here are some of the most common issues with the Hummer H2:
- Suspension System: The Hummer H2 is equipped with a sophisticated air suspension system that is designed to provide a comfortable ride, but it can also be prone to problems. Common issues include leaks in the air suspension system, which can cause the vehicle to ride unevenly or even sag to one side.
- Electrical System: Many Hummer H2 owners report issues with the battery draining quickly or not holding a charge, as well as problems with the vehicle's wiring and electrical components. This can lead to a variety of issues, including difficulty starting the vehicle or problems with the vehicle's accessories, such as the radio or air conditioning.
- Braking System: The Hummer H2 is a heavy vehicle, and this can put a lot of strain on its brakes. Owners often report that the brake pads and rotors wear out quickly, and that the brakes can feel spongy or unresponsive.
- Build Quality: Despite being a tough and rugged vehicle, some owners report that the H2 is prone to rust and corrosion, especially in areas where road salt is used during the winter months. Additionally, some owners report that the interior components of the H2 can feel flimsy or cheaply made.
These are just a few of the common problems that Hummer H2 owners often report.

- VIN: 5GRGN23U45H
- Components: AIR BAGS
- Summary: THE SDM (SENSING AND DIAGNOSTIC MODULE) ON MY 2005 HUMMER H2 IS NOT WORKING AND IS CAUSING MY AIR BAGS TO NOT WORK, AND ALSO CAUSES OTHER MODULES TO NOT BE ABLE TO COMMUNICATE AND CAUSE MY GAUGES AND OTHER ELECTRICAL ACCESSORIES TO NOT OPERATE (WINDOWS, LOCKS, ETC.) MANY OTHER HUMMER H2 OWNERS ARE HAVING THIS SAME PROBLEM. A NEW SDM WOULD FIX THE ISSUE, BUT GM FOR SOME REASON HAS DISCONTINUED MANUFACTURING THIS MODULE.
