Ask around on some Hummer forums, I have never heard of this or seen it.

Our 2006 H3, and 2004 Jeep Liberty both have this problem, it is specks of metal that stick to the clear coat, when they rust, it looks like the car is. I personally went out and bought ICE liquid clay bar, and it worked great. It actually looks better than when we bought it. But, it did take some work. Hope this solves your problem.

Also do the clay bar in the fall and the spring. Each time following it with a coat of wax!! It will shine like no other!

Once you get the "rust specks" off it is important to keep a good coat of wax on your vehicle.

Between waxes, pick up a bottle of something like express shine or a similar product, and give you car a quick spray & wipe after each wash. With all of the stuff in the air & atmosphere these days - it is a constant battle to protect your vehicle's finish.

I have a 2006 H3 with 47,875 miles. I had the head replaced under warranty last week. #2 cylinder had went out. Am debating whether to pay if off and keep it, or buy another used vehicle for the 14K that I owe. Other than that issue, it's been maintenance free.

I have a 2006 H3 Hummer. Hummer Mechanic informed me of factory default air intake system. GM would not honor, dealership wanted about $2000.00 to fix. Nothing but problems. They hit 50,000 miles, then nothing but problems.

No one even wants to take it on trade. If I can't get this matter resolved I'll never buy American again.

I own a 2006 Hummer H3, it currently has 54000 miles on it.

Within the last two weeks, I have had to have the transfer case replaced, the front differential replaced, the left front axle rebuilt (twice), and new brakes and rotors.

It is now back at the shop when the check engine light came on, mechanic said the first cylinder is not firing, and new spark plug and wires did not help. They are investigating the problem now and haven't told me the problem as of yet.

I am very disappointed in this vehicle. I don't believe a car should have this many problems with only 4000 miles beyond warranty. The fact that GM offered no help at all has led me to change my opinion of them and their product, I can't see myself purchasing another GM vehicle.

You title your review... "absolutely love it" huh... What makes you hate a vehicle? Rust and an engine rebuild at less than 40K miles would make me hate my car! It amazes me the level of poor workmanship people put up with, and continue to "love" their cars and dump more money into companies like GM, that continually put out poorly engineered products!

No wonder they survived for so long making sub-par, oversized vehicles... People just eat that stuff up, no matter how shoddy they are put together, don't they?

'06 HUMMER H3 with 67,872 miles... idling rough and hesitating upon acceleration. Took it to dealer and needs replacement head on cylinder #5. Warranty expired and will cost $3500! Called 1-800-HUMMER and referred to a district specialist who told me that I should have bought an '07 because it came with the 100000 mile powertrain (gee thanks). Reading online I have found that this is a known issue and GM is doing nothing to fix it. Both my parents and husband's parents retired from GM, but we won't be buying a GM vehicle ever again!

I have an 06 H3. I bought it with 44,000 miles. Had to have the head replaced out of warranty at 54,000. Then again at 59,000, and now needs it again at 64,000. I am very displeased, I love the way it rides and the security it provides in the foul New England winter weather, but I cannot get anyone to take it in trade in, and I will definitely not buy another GM product... it was a bad buy.

05 White BMW... same issue... solution, wax job as suggested.

I purchased a 2007 Red Hummer.

I've had no problems, until last week. I had noticed it idling rough. I took it to the dealer. They have had it over a week. They say the valves are being replaced. It only has 48,000 interstate miles.

Me and my husband have been loyal GM customers. But this bothers me. Wonder will I have more problems? I might consider trading it in. I have even taken it to the dealer for all services (oil changes, & tire rotations).

I'm shocked by this. "Foul New England winter weather"? I have lived in New England my entire life, and not once have I ever owned a 4WD vehicle, and I have only been in one accident due to winter weather in my entire 23 years driving. And that was in a Dodge Challenger with summer tires. It amazes me that people think they need something like a Hummer to get around in New England weather. Winter's here can be rough, but not that rough.

It's called slick marketing. This is why the roads are clogged with SUV's, because everyone thinks they need these big "safe" 4 wheel drive vehicles to get around in. This campaign has been going for decades now, and only slowed because of the fuel price increases. To feel you need to spend $1000's extra for a 4X4 for a couple of big snow storms per year is ridiculous. Here in NY, they clear the roads within 12 hours of any snowfall, so you may have a tough go of it for a short time, but never is it that bad that you can't get around in a normal car. Honestly, you should stay home anyway if the roads are not passable by anything but a 4X4. That's what personal days are for!

I have a 2006 H3, it has had multiple issues. At 80,000 mile the bracket that holds the front differential has broken. The dealer said they had never seen this in any other H3. Has anyone else had this issue with their H3?

31st Mar 2010, 22:20

I have a 2006 H3. It currently has 43K miles on it. No problems as of yet. I did purchase the extended warranty.

After the comments I have read, I am seriously considering trading it in for a new vehicle. I have had it off road and it did great. So to all of you with the problems, sorry for the trouble. If any issues do occur, I will be glad to report them.

2 weeks ago bought 2006 H3, with 54,000 miles.

First week the upstream O2 sensor went, dealer had it for 3 days. Got it back 2 days later, now it's a vent solenoid.

I was passionate about buying this vehicle, but WOW, not looking to drive the dealer's loaner more than my own vehicle. This will be the last try, if it goes back in the shop before its 30 days are up, it's back to Dodge for me :(

I am having the same problems with my 06 H3, we've sunk thousands into replacing part after part since they started happening 50 miles out of the 50k mile warranty. I'm organizing a class action law suit against these faulty vehicles and horrible co. GM is. Please contact me at sarofool151@yahoo.com ASAP and help us get back our lost monies. Thank you.
