The addition of second-row captain's chairs, a heated, power-tilting steering wheel, and OnStar Destination Download combined with last year’s upgraded interior elevates the comfort and convenience of the 2009 HUMMER H2 to a level worthy of its retail price.
Even with the recently redesigned interior, however, you wouldn’t want to drive the 2009 HUMMER H2 on a long road trip—the H2's interior is cramped, and the effective use of space takes a backseat to the styling. A rear HVAC system is now standard, as is a Bose surround-sound system. The H2’s cabin also features a recently redesigned dash, squared-off seats, a third-row seat for two people, and a rear-seat DVD entertainment system. Cars.com says that in "addition to its more sensible, refined shapes, the dashboard features glowing blue gauges and trim that's among the best faux-metal finishes on the market."
The front seats are what Car and Driver appreciates, saying that "the front seats were comfortably reshaped for 2008." That's all well and good for the driver, but Kelley Blue Book brings bad news for passengers, stating that "the interior of the H2 is snug in the areas of rear-seat legroom and cargo space." A third-row seat has been wedged into the H2 HUMMER for the first time, but it’s tiny and difficult to reach.
Car and Driver mentions that "even the gangliest of staffers had a hard time getting into and out of the truck," but this can be mitigated with optional running boards. More minor complaints are raised about the wind noise and cabin height of the 2009 HUMMER H2. ConsumerGuide observes that "there's marked wind noise above 65 mph," but on the plus side, "engine noise is well muffled."
