  By Hummerfan - October 27 - 7:56 am

  Purchased new almost 9.5 years ago and have put on 148,000 miles. It has been a GREAT vehicle with no problems. Have only replaces tires, battery, water pump and brakes. Really a fun and luxurious vehicle. Still commands looks!

  Love the hummer - 2006 Hummer H3
  By jdicataldo - August 5 - 1:13 pm

  I owned a hummer h3 2006 for over 6 years. I drove over 150k miles on it. When I reached the 100k I took it to the mechanic asking to check it for any maintenance since the mileage of the car and basically just replaced the spark plugs. Nothing else. I change my first set of pads (brake pads, no rotors} on 110k miles on the front wheels, and on 130k miles on the rear wheels. Just had to believe but true. Sold it on 2013 with over 170k miles and running perfect. I missed it so much that I just bought my second h3 a month ago same year with just over 100k miles. Took it to the dealer to do whatever needed to have the peace of mind and runs incredible smooth (even better that my last one since I put four new Michelin on this one). Super smooth ride and very happy with it. I m just buying all the option that I used to have on my first one. I recommend this suv to anyone. The look is great, the comfort, the driving position, everything. Some complaint for poor visibility but with big rear mirrors as it has and back up camera that I added I feel very confident parking or anything. Not very powerful acceleration but small engine gives you better MPG so something has to give up. Anyway is enough power for everyday needs.

  Best SUV Ive Owned - 2006 Hummer H3
  By jusncsu - January 28 - 12:15 pm

  I own a 2006 H3 w/ adventure package. I bought the vehicle used in 2009 with approximately 30K miles and an existing factory warranty. Hands down this is the best SUV Ive ever owned. Its extremely comfortable, performs as needed and has been nothing but reliable. Ive never had anything other than routine maintenance performed (knock on wood). My only complaint (if I had to give one) is that it doesnt have a ton of cargo space. My wife and I didnt have any children when we bought the car. However, we recently had our second child, and with double strollers, etc. are in need of a bigger SUV. However, I am not going to trade or sell the H3 Ill be keeping it forever!

  Hummer time - 2006 Hummer H3
  By prodigy1 - October 10 - 1:19 pm

  I bought a 06 h3 adventure package with 80k miles on it and was surprised at how well it rode and performed with the mileage it had. Every one gave me hell about having a hummer but I loved it. Driving it makes you feel like a kid driving a tonka toy. The Mpgs where average for its class 18-22 mixed driving. It was comfortable on short and long drives. It never gave me any issues and it never got me stuck off road. If your debating between an h3 or a wrangler, get a h3. You get more for the money and insurance is less. You get better Mpgs and a nice comfy ride when youre not plowing through the woods or mountains. Its a solid ride.

  2006 Adventure Package - Love this Car!! - 2006 Hummer H3
  By jusncsu - December 5 - 1:11 pm

  Ive owned it for a few years now (did a great deal of research to ensure that I wasnt purchasing a lemon) and I love this car more and more the longer I own it. One of the commenters on here had a great point. Get it serviced at your Cadillac or GM dealership, and keep up the maintenance!! Ive heard a few comments regarding the lack of power/acceleration due to the size of the engine. This thing isnt a sports car! As others have said, it will easily get up to over 100mph. However, you shouldnt expect to get there in 6 seconds - who buys an SUV with that in mind?? Great car, Im keeping mine forever!!

  American Collectors Item - 2006 Hummer H3
  By ghostrider8 - July 18 - 12:14 am

  I was by a bank that Hummers are investments as the demand for Hummers is huge.The H3 has been a great, fun, rugged,strong & qaulity.The engine has pep in town,but most of the power is torque for pulling & climbing in hard terrain.Most that complain about them either have not taken proper care nor servced at a Cadillac or other GM desler.I had to cut off road in terrain that big 4x4 trucks could not go in,the H3 went through with no problems without even having to use 4 wheel drive.H3 is heavy & is designed to basically go anywhere,it is not a Ferrai,it is a Hummer built to in the harshes environment & it delivers.Open speed the H3 has no problem cruising at 100 mph.It is just cool.

  giant piece of junk - 2006 Hummer H3
  By lodown - June 7 - 2:44 am

  Bought this pre-owned at 5 years old. Conveniently everything started going down the drain at that point. Stupid things would break like the door... couldnt open the driver door from the inside. Sunroof leaks, passenger will randomly get quite soaked. It seemed like every week something would go wrong. Key fob just doesnt work... tried changing the battery..nothing. One day I tried to go to work and the truck locked me in park! Couldnt move the vehicle! Extremely unreliable. One day hazard lights just turned on its own and wouldnt turn off. Cant even drive up hills without a hard time. No interior lights that turn on when door opens - stupid. Poor handling.

  The True All American SUV! - 2006 Hummer H3
  By ghostrider8 - June 3 - 2:57 am

  (Note mine is automatic,online drop box only gave one option.)The style & design of the H3 is a head turner,it is unique,rugged,&can practically go any place. IF YOU BUY ONE, ONLY SERVICE IT A GM DEALER LIKE CADILLAC THAT DEALS WITH ESCULADES,BUT STAY OUT OF OIL LUBE & TUNE SHOP.The H3 is a fun vehicle to drive,has the most powerful A/C & Heater I have ever had.It is well built & reliable. They are now becoming some what of collectors items where Hummer Owners Clubs are growing & it has been speculated to be one vehicle that will increase in value.

  Never Again! - 2006 Hummer H3
  By attaboy33 - May 14 - 10:45 pm

  My happiness last for about 3 months until the sunroof began to leak and hasnt stopped since. I have taken it in 5 times and each time they only want to replace the drain hose. I bought it preowned and learned after 2 years of ownership that the problem existed prior to purchase and it was never disclosed, now the warranty is up and they refuse to fix it. The leaks have caused stains on the seats, a foul odor, possible rust. It is now currently under investigation by GM. Not to mention all the other problems listed below: tire monitor unsteady alignment hood latch recall 2 new batteries electrical issues 2 a/c issues repaired rattles shocks have gone out and I only weight 175

  Road King - 2006 Hummer H3
  By k0pir - April 29 - 2:10 pm

  Whether your on the highway or on a dirt road this hummer h3 is a road king. I love my 2006 Hummer H3 Luxury. From the heated leather seats to the big open sunroof, this is one amazing vehicle. Its not a car, its not a truck, its not like any other SUV, its "like nothing else." Go any where, do any thing, they completely make an average trip a real adventure. If you like the outdoors, camping, getting away into the wilderness and dont mind getting stares from bystanders on the street, youll love the H3.
