I love the look of the Hummer H3. It just has a great presence. However, that said, engineering wise they didn't do a great job. For instance, I have heated seats and they repeatedly go on when getting into the vehicle, both driver and passenger sides. Also, the metal whip antenna hits low hanging branches often. This is an off-road vehicle so why have that extra interferrence. The Typhoon radio is awesome with a separate sub-woofer but they didn't include an i-pod interface or even a play connection. The vehicle is heavy yet it corners unbelievably and has a great turning radius. Gas mileage is no worse than say a Jeep. About 14-15 mpg around town. Havn't check highway trip mileage yet. The engine is sluggish but then I didn't buy it for performance.
Overall, with the exceptions noted, the H3 has been very good. No issues so far. Luckily still under full warranty for peace of mind. Too bad they (GM) didn't have the time to let the engineering evolve.
I owned it for 3 months and had to get rid of it, it was becoming too much of a problem. It was in the shop for 2.5 of those three months I owned it. The sunroof repeatedly leaked and was repeatedly repaired. The drainage issue also caused water to get inside the vehicle constantly and left aweful odors. The engine light came on for a temp sensor, needed an alignment, brakes and rotors right away, the ignition had to be replaced as it left me stranded several times due to passlock failure, the windshield wipers would intermittently work or not work. The last straw was more electrical issues. The blower motor would intermittently work, all tue lights kept turning off and on, the door locks would lock and unlock themselves, ecu went bad.

What a excellent vehicle! It has a substantual feel - very solid. For a four by four the ride is very good. Excellent space for others and gear. It has to have the best stock stereo system ever. It will blow you out! Off road, it can handle more than I feel comfortable trying to drive over. Would like a little better milage per gallon, but all in all, I would not want to drive anything else.
They’re big. They’re bold. They’re kinda in your face. Tall pickup trucks and SUVs have the kind of ride height that gets you over, through, and around the kind of rough terrain which stops other vehicles in their tracks. If you live in a place with lots of snow, mud, or uneven ground, ride height (defined as the distance between the bottom of your truck’s tires and the lowest point on the underside) is probably more important to you than road-hugging and handling characteristics and strong fuel efficiency.
