got my check engine light this morning in traffic

I'm seeing more posts about head problems.
When are the build dates of these vehicles? And is there a fix that was put into effect after a certain VIN #, that would exclude these later VINs from the Head issues?

The reasons for trading in my 06' for an H2 just keep mounting.

well i have never had any starting issues or whatnot, it seems to have all of its power, altho i did notice that sitting at lights idling the motor will have just an almost unnoticable rough spot every 20 seconds or so. basically they said one of my cylinders is leaking, so it needs a new head, and to go ahead and drive it and they will give me a rental car when i bring it in for service.

Now as to opening a case, what do you mean by that? i called hummer yesterday and was talking to the guy and said "so i gotta get a new head and im worried this will happen in the future, where do we go from here" and he said i got the 4yr 50k warranty and if it happens again they will put a parts note on that part i guess and extend the warranty on that part. how do i get the extra coverage you guys are talking about? pm me if its best kept off the forum.

I had the cylinder head replaced not too long after I bought my H3, but they wouldn't give me anything as a warranty extension. They said, "It's fixed and you won't encounter the problem again." The Service Mgr said they had several H3's in for the problem, so they were aware of what needed to be done. Thankfully I haven't had the problem come back (at least not THAT one ..lol). That was about 1.3 years ago.

We have a company vehicle that has been running for about 7K now, with the cylinder head issue. I know a few who have traveled well over 3K with the cylinder head issue. So, it appears some can.

As for cutoff. The new cylinder head for the 3.5L went into production March 31, 2006. So, vehicles with engines built after that date would have the new cylinder head. However, the plant could have had some of the older engines on site so I do not have a VIN cutoff for vehicles.

F5, There are small white sticky bar coded labels all over the truck, hidden away in the dash, and on parts of the chasis indicating the date and various times for different items. One example wasn't really secured so I pulled it off and kept it in my file for reference.
It says, " D8X 00503671 3/27/2006 12:41:32 PM Commodity: Steering Column" .
I am guessing that this was the Build date for my truck, and the various times indicate when that componnent was installed on the line?

Based on this, I must have an old style head. Should this be a concern? Is the problem wide enough spread that there may be a recall for the '06 Heads?

My last eight are ...68282011

Sorry, Neo, but you're still at risk...

Took my H3 in today for a tire rotation & full checkup before heading out West next month, dealer called & said they read error messages, my head's gone. They said I had a valve hanging, sounds like worn guides.

Built July of 2005, I got 41000 mi & thought I may be safe.

Good news? I can have it back tomorrow. Sweeeeet.
