good luck dude, sorry to hear it.

[Desert Dan]

I feel your pain dude.

Mine goes into the shop monday am for the head replacement.
Get on the phone with GM and get a file started now.

Request extended coverage on the engine.

Sorry to welcome you to the club.

Got mine back from the shop today, ten days after dropping it off.

Seems to be running OK, a little rough if you ask me. I guess I'll see if it smooths out.

Hummer extended the engine coverage to 7 years/100,000 miles after opening a case.

I got the Engine Light Warning this morning, idling rough, turned it off, let it sit, tried again, same thing. Called OnStar, they didn?t tell me anything, accept take it in to the dealer NOW. I was still able to drive it, but the computer limits your power, so I could only do a slow crawl down the feeder roads, until I got to the dealer, luckily for me it?s only 5 miles away. They haven?t called me yet, to tell me what?s wrong. When they do I?ll try and keep you informed on my outcome.

Did anyone change there PCM, or have it tuned and then have the Head problem come up? I?m asking because I had my PCM tuned and installed it last week ?everything has been running GREAT? until my problem this morning. I have a ?06 with 33000 miles.

[f5fstop]

Has nothing to do with the PCM or the calibration. Totally a cylinder head issue.

[D-Lux]

Thanks, that's good to know. I didn't want to take that PCM out again, that was a pain plugging it back in.

My head cacked at about 19k miles. I am over in Gmbh and can't get to my vin # right now but I know my Hummie rolled off the line in Sept 05', so it was one of the first, and like I said in another post my Hummer Dealer has seen a lot of the first ones with these "weak" heads and customers cracking them because of either towing, or high stress on the engine. He took 4 days to do mine, but I also had him do the 20k service and fix a rattle in the rear passenger door. I know he also replaced some other parts on the engine, but can't recall what they where.
When I get back to the states will get my paperwork and see what else he replaced, but all I know is my mpg almost doubled after I got it back.

ok, then drive the mother! I got a 07 now so i don't care anymore

I would love to see the last eight of the VIN. Reason: Dealer is full of poopie, I did some checking today, and there are only two cases of cracked heads. Damaaged heads due to abnormal wear of the valve guides is very common on early heads, but cracked....dealer BS. (Not you, dealer. You are only repeating what a dumb a&& dealer is telling customers; thinking it makes them feel better.)
