The cargo space issue is obvious. When a vehicle weighs 6,400 pounds and meets the heavy-duty vehicle classification (and therefore isn't subject to pesky EPA gas mileage estimates), you'd expect it to double as a moving van when needed. However, the H2's cargo bay is occupied by the aforementioned spare tire and third-row seat, and even on large grocery trips, one of these has to come out to get everything in. On the plus side, the 60/40 second-row seats fold easily to create a flat load floor.
Inside, editors noted GM's attempt to give the H2 a bold, masculine ensemble but wrote that the final product seemed like a rush job with various elements thrown in at the last minute. Low-quality materials certainly didn't help ? there was hard plastic in abundance, along with weak leather and vinyl trim and unconvincing faux metal where there should have been real stainless steel. "Nothing seemed worthy of such an expensive vehicle," one editor wrote in his evaluation. Build quality wasn't perfect, either; panel fits weren't all that tight and the shifter, one of the few stylish holdovers from the H2 concept truck's sharp interior, wiggled in its gate.
