Overview & Reviews

A new "Alpha" trim level debuts for the 2008 Hummer H3, giving the pudgy SUV what it needed most -- a serious infusion of power via a 5.3-liter V8. Other notable changes this year include standard side curtain airbags and the availability of a rearview camera.

• Serious off-road ability, smooth ride on pavement, stable handling, simple cabin controls, comfortable seats.

• Tepid performance with inline-5, poor outward visibility for shorter drivers, subpar cargo space, terrible gas mileage.

  More comments on Hummer than C6 - 2008 Hummer H3
  By LuvsHummers - November 2 - 2:00 am

  As a previous owner of an Escalade and BMW X5 I am impressed. The Alpha has plenty of power when you need it and cruises smooth at 85-90. This thing is build very tough and think it is the ideal vehicle for anywhere. If the term MPG is even a worry keep looking, while I do get 15-16 hwy it isnt pretty when driving in traffic. Overall I think this is a nice all around vehicle but not quite the space of larger suvs. Went between this and a H2 and chose the smaller, and am happy with that choice.

  Wish they still made them - 2008 Hummer H3
  By warmhiker - September 14 - 2:00 am

  We bought our first H3 in 2006 and just bought another used for me in 2010. I SO wish they still made these! Most comfortable SUV out there. Absolutely love the drive and I dont get run off the road out here in TX! Only complaint is takes forever when you step on the gas, but put in a shot of Gumout fuel injector cleaner, and gave me a little more umph! Despite be the best vehicle Ive ever owned (out of 10!), if you get a chance, get the extended warranty. After 4 yrs., the security system and engine coil had to be replaced ($1200), but thats about it. If they still made these things wed get another. Wish someone would buy Hummer and keep in American!

  Best Looking SUV Out There! - 2008 Hummer H3
  By H3 Owner - August 5 - 2:44 am

  Just bought my H3 luxury with 40,000 miles. I love the exterior and interior design. The engine is only a 3.7 and its a little underpowered but its not TOO bad. I think GM should of put a bigger engine in it. The fuel economy is whats expected from a mid- size suv. Im getting about 17 mpg combined. I think the interior set-up is one of the nicest from GM. The visibility is not great but not a big issue for taller drivers. The leather is very comfortable and the sunroof is huge! The monsoon system is banging. It turns heads like crazy! I love this car and wont get rid of in until the wheels fall off!

  Confident Truck for a family guy - 2008 Hummer H3
  By HuskerHummerowner - January 12 - 12:50 pm

  As a former single Dad and now father of 8 I wanted a truck that never let me down regardless of road conditions so I could always get to my kids or get them where they need to be. H3 is for me! Comfortable, fun, unique, and the power of a full-size truck without the waste of a flat bed I didnt need. Sightlines are nice, ride sits high, and people who know how to use mirrors should have no problem with the Hummer. Back-up assist is nice, but not required if you use your mirrors. Do not buy this truck if you are going to stress about gas! Love the combination of substance under the hood and style throughout! The 4Runner is great under the hood, but cant touch the H3!

  Hummer Alpha V8 - 2008 Hummer H3
  By Offroading - December 7 - 9:56 am

  Excellent vehicle ... lots of power for passing and going uphill with the v8 power. Simple instrumentation and large knobs make it easy for adjusting when the vehicle is going offroad. Get the BF Goodrich tires TA K/O .... better traction

  Hummer Alpha 5.3 V8 - 2008 Hummer H3
  By Great - December 1 - 2:59 pm

  4runner owner before ... great to have a V8 powered vehicle ! much more power for towing. Instrumentation is well layed out ... but could use more convenient features on the steering wheel like the H2. Memory front seats would be a nice feature. Ipod and USB ports for the stero system is missing.

  Hummer Alpha 5.3liter V8 - 2008 Hummer H3
  By Lee - December 1 - 2:39 pm

  Vehicle is very comfortable for long rides, visibility for the driver is limited but you get use to it. The V8 engine is great for passing and climbing up hills. There is some wind noise but to be expected from a Hummer. Suggest to use BF Goodrich TA tires ... better traction than the Goodyear all terrain tires. Door side pockets could be bigger to hold more stuff.

  Windshield - 2008 Hummer H3
  By Kurt Watson - November 6 - 11:51 am

  This is my first Hummer and I am impressed with everything. The only complaint I have with my Hummer is the windshield. I am on number three in less than two years. The design of a flat glass gives Hummer that "look" but it is a sacrifice to rock chips and easy breaks in the hot Texas sun. A nice option would be high impact or bullet proof glass.

  No Regrets - 2008 Hummer H3
  By scout70 - October 8 - 12:12 am

  During the 1970-1980s I owned several International Scout vehicles. They were tough and unstoppable off road. Thereafter no vehicle really took its place. Jeeps just dont cut it and are of the cookie cutter variety. My Hummer is big, tough and safe. Fun to drive and I have been caught in several big snow storms. The H3 can go anywhere and is always reliable. I have no regrets about buying this car. Mine is loaded with all of the options which makes it nice. Dealer support is excellent.

  2008 H3 - 2008 Hummer H3
  By Karen Kraft - September 28 - 1:08 pm

  Bought this for my daughter who is a brand new driver. Wanted a "tank" to protect her - we LOVE IT. It rides great and I feel better knowing she is in a tank. Handles really well - didnt know much about these but since most of the new inventory at the dealerships were low and they werent dealing because of the cash-for- clunkers, we went the used route. Went looking for a truck - buying the hummer h3 was a whim but we are very happy with the vehicle.
