When problems show up
No complaints for this year listed a mileage, so we can't say when problems show up.
Questions to ask the seller
- Were recall 10V240000 (electrical) done? Ask for the dealer printout, or check the VIN.
- Any oil burning, leaks or check-engine lights? Ask for oil-change records.
- Any slipping, hard or late shifts, or a transmission warning light? Ask for transmission fluid service records.
- Hummer sent dealers 986 repair notes for this car. Was this one done: “Flare and or harsh 2-3 shifts”?
From this year's own recalls, top problems, top repair bills and Hummer's repair notes. Recall repairs are free at any dealer.
How serious. Out of all 1 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

Every Hummer H2 year. 2009 is highlighted. Lower is better.
Newest year first. Red = worse than average, gray = about average or too few complaints to score. #1, #2… = that year's YouTube rank among the 7 Hummer H2 years with enough videos (#1 = the year owners and reviewers talk about most positively). It is not a reliability rank.

What Hummer H2 year is better than the 2009?

The Lemon Index counts owner complaints filed with the U.S. government (NHTSA) in a car's first 3 years, per car sold, against the average car of the same model years (100 = average, lower is better). It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
