What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2009 Hummer H2, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
SINCE AUGUST OF 2009, HAVING PROBLEMS WITH ENGINE/TRANSMISSION. VEHICLE "DIED IN FLIGHT" IN AUGUST, VEHICLE COUGHS, STUTTERS, AND STALLS OUT EVERY DAY AT FIRST START-UP, AND I'M EXPERIENCING HARSH SHIFTING DAILY. I'M ADVISED THERE IS NO RESOLUTION TO THE DAILY STALL-OUT PROBLEM EVEN THOUGH THE VEHICLE HAS BEEN IN TO THE SERVICE DEPARTMENT FOUR TIMES SINCE 8/6/09. ON LAST VISIT TO SERVICE DEPARTMENT I WAS ADVISED THAT "GM IS AWARE OF THE PROBLEM BUT HAS NO FIX FOR IT" (CASE #11074714). *TR

Suspension
Reports naming suspension components — springs, struts, shocks, control arms and related hardware.
From owner reports, verbatim
BOTH REAR LEAF SPRINGS BROKE RIGHT AT THE FRONT "SPRING EYES", CAUSING THE REAR TO SHIFT TOWARDS THE BACK OF THE VEHICLE, THUS ACTIVATING THE EMERGENCY BRAKE AND CAUSING THE VEHICLE TO BECOME INOPERABLE. I'VE READ OTHER SIMILAR COMPLAINTS ON THE VEHICLE THAT SHOWS THAT THIS THE LEAF SPRING DESIGN WAS CLEARLY A MANUFACTURER DEFECT.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
