Pros: What do you like about your 2006 Hummer H3? The exterior design. The overall steering tightness. Gear ratios (I have the adventure series, standard 5 speed). The road respect (no cutoff's, tailgater's, etc.). Its 4x4 ability. Comfort of driving especially on a trip. Towing the trailer.
Cons: How would you improve your 2006 Hummer H3? Correct the fact that the vehicle cannot sustain a "3" mph front end hit without the rack and pinion coming apart and you have severely impaired steering ability. As well as the front wheels coming unaligned. Loose the blind spot at windshield ends. Bigger, and or magnified mirror glass (whole and small spot) to cover blind spots in back and sides. Move the spare, it makes the door too heavy, and you lose any option as to door configuration. Side by side- vertical or horizontal. As the "Adventure Series" a few more standards should be included. Such as a roof rack, or at least rails, back-up light.
2006 Hummer H3 Review: Very Poor, based on the fact that the vehicle cannot sustain a front end bump (3mph) without jeopardizing the driver's, any passengers', or other vehicles' and peoples' safety. Regardless of the situation at that force of impact. The 3 star on performance rating dropped on my experience with the rack and pinion breaking so easily. That one factor dropped my rating 2 stars, and the cost of $900.+ to me. Be careful folks !! Offroader's, be very careful !!! I was lucky, in a sense, I wasn't in the woods farther than one could walk. I'm a 100% Disabled Vet. Thanks Hummer, Thank God I flew Hueys.
