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.
2006 Hummer H3Mc Lovin - Abilene,TX06/26/2009
Only had the H3 for a month, but am overall very satisfied. This is the first suv I have owned Ive always owned pickups, but suprisingly am not missing it. The H3 rides good on and off road and I have definitely tested the 4x4 capability to the max and can tell you that it does everything that Hummer says it will do. The only thing negative I could say about the H3 is that I wish it had a little more power. I have the I5 motor in mine and when you get into hills it tends to stay in passing gear a lot of the time. This is the first GM product I have owned and have got to say that their service department is the best I have seen. The dealership I went to had a friendly and professional staff and had one service writer dedicated to the Hummer brand.

This is the funnest vehicle I have ever driven and I have been driving for a ton of years.!
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.
