Overview & Reviews

The Hummer H3 sees both aesthetic and functional changes for 2007. A new "H3X" trim level includes chrome accents (including front brush guard and wheels), embroidered headrests and unique colors. Stability control becomes standard, the engine becomes more powerful and the powertrain warranty is extended to five years/100,000 miles.

• Very capable off-road, smooth highway ride, stable handling, stylish interior with simple controls, comfortable seats.

• Tepid performance, low tow rating, lousy outward visibility for shorter drivers, below-average cargo space.

  A real Let Down - 2007 Hummer H3
  By engineer - January 22 - 7:19 am

  Bought this brand new 5 months ago... injector issues,misfires,horrible fuel economy with only 5k miles. The vehicle averages 11MPG city and 14MPG hwy. The ride quality is nice. The interior room is poor... even with the back seats folded down, there is no usable space. The 5 cyl engine is always straining to keep it moving and not having a 2wd only option eats the front tires. This vehicle has no tow abilities and with the spare tire mounted in the middle of the rear makes it tough to see out the rear window. Overall, I wish I had kept my Yukon.

  H3 - 2007 Hummer H3
  By bummerhummer - April 2 - 11:46 am

  Its a shame that after a year GM couldnt correct a problem that was occuring with their 5 cylinder engine. Maybe this is why the foreign cars are taking over the US market. H3 is not up with the times as far as technology and has poor engine performance.

  Slow Pretty Box - 2007 Hummer H3
  By Sgt. R - December 6 - 4:17 pm

  The H3 is underpowered. It barely can maintain 75 MPH on the highway and if you go up any incline the MPH will drop. The SUV gets poor MPG for a five cyl. engine. I like the look and it is nice off road but dont do any long distance highway driving. Interior is bland. Lots of mods available.It just isnt a real hummer. Should have more power and that would make things a lot better.

  buy American? - 2007 Hummer H3
  By timberridge101 - September 27 - 3:34 pm

  After having several German car.I thought Id try American. The trim, paint, body molding & overall fit are not what I expected for the top of the line limited H3X. Ill keep it if the weather requires emergency transportation. GM was going to offer after market kits to dress it up. I cant find any performance products that will fit. By the time I get this SUV set up the way I want. Ill just go back to Porsches SUV-S and drive.
