  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

  not so great H3 - 2006 Hummer H3
  By kris karpinsky - October 30 - 11:53 am

  Engine is way too weak for a truck this size 3.5 l. 5cyl its a JOKE!!! This truck is clearly made for women driving to and from grocery stores Every single friend of mine who was driving my H3 is saying same thing great handling more like a car not truck, quiet and comfy inside, good looking interior but engine is so weak !!! beige leather got dirty after two weeks of driving ( Im driving to work 22.5 miles one way) probably because my black leather belt and jeans believe me Im using AC and Im not over weighted & 200lb. (by the way enough space inside to get in and out)

  Needs V8 - 2006 Hummer H3
  By Ryan - March 10 - 9:03 am

  Test drove H3 and as I expected, way underpowered. I am a V8 kind of guy and a truck as heavy as this needs alot more than a 5 cylinder with HP and torque in the low 200s. Will consider purchase when a real engine is put in vehicle.

  Not safe for children - 2006 Hummer H3
  By DAWN JANNUCCI - October 27 - 4:40 pm

  My husband bought an h3 for me for christmas coming from a ford expedition i was really disappointed. The h3 is cute from the outside ,but it is really small, worst part the h3 does not i repeat does not have child safe rear doors. which means that a child can unlock the door from the inside back seat of the vehicle . I called the number in the back of my owners manual and was told that hummer could not even install them for me. I do not believe that a car that a child can open that easily is even remotely safe for them.

  Not worth the name - 2006 Hummer H3
  By Sheila - April 15 - 9:56 am

  The truck has been nothing but problems. We had a Trailblazer which had a lot of problems so we leased an H3 because of Hummers reputation. It has 27K miles, they have already replaced all 5 cylinders, worked on tire pressure monitor, it does not start whenever it does not feel like it and now the heating and air conditioning does not go on, no blower, nothing! They really just beefed up a regular SUV and called it a Hummer. Shame on GM.

  Not Happy! - 2006 Hummer H3
  By Not Happy !!!!!! - January 24 - 1:42 pm

  Ive had my H3 now for 19 months and it has been in the shop 4 times. TV monitor went out, heated seats quit working. Ive had it in 3 times just for the 5 speed manual. It wont go into 1st, 2nd or reverse gears..I have to almost brake the gear shift to get it to go into gear. I get stuck at lights and traffic with people blowing their horns because I cant get it into gear. I took it in twice and they said it was fine, they couldnt find anything wrong until I went for a test drive with a mechanic and he said they would replace the stick shift. It worked great for 2 weeks and now Im back to not being able to get it into gear. Doors lock & unlock by themselves now, eletrical problem.

  Gm swings and misses - 2006 Hummer H3
  By Car lover - June 12 - 8:06 am

  Owned the the car for 3/4 of a month. She looks good and rides as comfortable as my gramps caddy. But the onstar never worked!!!! She is a slow as a snail!! I understand the idea was mileage, but 0-60 is only .2 seconds faster than my 1995 ford explorer. Also the cargo room is horrible! When your in colledge 55ft aint cuttin it! Further more my salite radio broke recently, Yet GM is still makin me pay for it. It seems to me that until GM can get its costs down and build things right you should look but dont buy!!!!!!! Until these GM reliabilty/build quality issue have proven themselves fixed I am questioning the thought of buying that corvette I was thinking about.

  What a joke? - 2006 Hummer H3
  By spdrmanus - May 23 - 6:45 pm

  I bought this so called Hummer and within 3 months sold it. It is totally lacking enough power for the weight ratio. Had it stuck on numerous occasions all because it did not have the power necessary to pull out. Traded it in on the H2, spend the few extra dollars and get the real thing not the wannabe.

  my post repair review - 2006 Hummer H3
  By Car lover - September 4 - 9:56 pm

  Last time I wrote I was annoyed at some technogly issues. The Hummer sevice people fixed them. Now I will objectively state the pros and cons of the H3 based on mine.The are pros good gas mileage for an SUV, show stopping looks , nice interior for GM , decent handling characteristics , roomy back seat, and the ride comfort of (I have ridden in both of these cars) a Lincoln Town Car and Cadillac Deville/DTS . The cons are not enough horse power and torque for sporty driving , getting to highway speeds easily, or towing, poor rearward visablity , and poor cargo room. I consider eather waiting for the SRT8 Jeep(45k). If you can afford it the Range Rover Supercharged(90k)the best SUV in the world
