Here's the story:

Last week I noticed the engine was running a little rough at idle.
The following day the engine light came on and would not go out. I took my H3 to the dealer the following morning. After about 30 minutes they came back and told me I had the same problem as two others they already had.

I'm not a engine expert to any means so I will do my best to explain what I was told.

To the best of GM's ability they think the computer is running the engine too lean causing a overheating condition in the cylinder. This causes the valves to burn and make it not seat well. This in return causes a low compression problem thus the computer engine light.

GM has told them to replace the entire head and everything related and update the computer code to fix the lean problem They have also been instructed to send in all replaced parts for them to examine.

That was Sat I called today to check and see the status and found out the now have 5 with this problem.

This is looking very bad.

I had 12,000 miles the previous two had 7 and 9 thousand.

He mentioned that they had a problem with the Colorado at one time with a similar issue but GM says this is different.

He told me that the head has to go into a machine shop to get worked when they get the parts.

GM told him they are getting more and more of these everyday.

I wonder how long it will be before they start a recall. I guess when they determine the exact course.

I wish I had never bought my H3. I shoulda known better.

Well...at least you learned your lesson. Now...go by a hybrid.
Idiot.

Thanks for your wonderful input. You are so helpful.

Kick a guy while hes down why don't you.

Don't get me wrong I love my hummer. But I'd really love it if I could drive it.

Gees can't a guy vent!

Sure doll. You want to vent, this is the place to do it.

You love your hummer, but wish you never bought it??

Don't mean to kick you while your down. I'm just feeling a little feisty today. Please..continue.

OK let me rephrase.

"I wish I had waited till there was a proven track record for the H3."

I'm thinking call me crazy but if there's 5 in my dealership in two weeks. There might be a problem.

I don't like the idea of my engine basicly being rebuilt after only 12000 miles.

Would you?

Hopefully they will nail down the problem and put out a fix so others will not have to go through this.

I only posted to see if others are having problems.

Besides I like em Fiesty.

fiesty or PMSing?

Thanks for the "heads up"

When your first post ends with that line, expect to get some sh!t for it.

Sucks you're having problems, but that's what warranty is for. Could you maybe go into more detail on the symptoms so others on here would know what to look for. Just in case this does become a common problem.

Good Boy. That's better.

Don't be ugly Mike. I know where you live!

I know I should of waited more than 2 minutes after getting off the phone with the dealer.I'm much calmer now.

The only symptoms were a rough idle (engine shimmy) Then the engine light came on within a couple of days. It did seem there was some power loss.

They said the compression on 2 cylinders was low 150 on one and 180 on another.

I think he said below 200 was a problem.

I just have to ask, "do you really believe what a dealer tells you."
Whether there is a problem or not with the cylinder head

"GM has told them to replace the entire head and everything related and update the computer code to fix the lean problem They have also been instructed to send in all replaced parts for them to examine."

Sending back parts can be a standard procedure, depending upon the parts. I haven't checked, but I'm sure this part is considered a core return part.

"He told me that the head has to go into a machine shop to get worked when they get the parts."

Now, I'll be honest, this line makes me laugh. If the dealer is getting a new head, there is absolutely no reason for them to send it out to a machine shop when received. The head will be ready to install right out of the box.

"I wish I had never bought my H3. I shoulda known better."

I guess all other trucks/SUVs/cars, etc., can never break...damn, wish I had known that.

Excuse me, but for some reason, I have a hard time believing a first post with the statements you have made. Either this is a troll post, or you are exaggerating the problems, or the dealer is really in bad shape.

My diagnosis: Troll Boy

I am a little confused or you are. The title AND you stated in your opening post that the head had to be replaced. Yet you followed that up with the fact that you are waiting because "He told me that the head has to go into a machine shop to get worked when they get the parts."

Apparently I am not the only one confused.

f5 nailed it

If he had gotten a Prius this would never have happened.

He said the head has to be fitted to the valves or something. Like they had to be matched. He said is more of a polish/sandpaper thing. He said he could do it in house but he has hired a local machine shop to do it because "they do it every day". Or maybe it's because they have 5 of them. I don't know.

This is a fairly large hummer dealer they sell 40+ H3's a month.

Hell I don't know maybe they are lying to me and their out muddin.

As far as the "I guess all other trucks/SUVs/cars, etc., can never break...damn, wish I had known that."

I have never had a vehicle with this large a problem after only 12000 miles. Actually never less then 130,000 miles. In fact I don't know of anyone with this large a problem on this many vehicles.

Maybe I've just been lucky

Come one 5 in two weeks?

this many vehicles ? you said you heard of two besides yours thats not many
