Has anyone else had to have the entire head replaced? I smell recall.

Call Customer Assistance at 1-866-HUMMER6 and open a case. Demand was probably the wrong word to use. But explain what problems you've had and what you have been through. Then ask them to upgrade your warranty. Obviously, there's no guarantee they'll give you anything. They may just offer GMPP or service vouchers, or just extend the warranty on the parts that have failed. And yes, some of us have been compensated in some way when we had major recurring problems.

I called Customer Assistance yesterday and today they gave me an 84 month 100,000 mile warrenty extension on the engine only. Seems fair, I did ask for the warrenty to be extended to the entire drivetrain but they weren't willing to go that far.

I got my H3 back today, after almost three weeks in the shop. The new head is performing perfectly so far.

Thanks for the suggestion, it certainly paid off for me!

I noticed originaly heads went bad with lower miles,now I see some have higher miles.
Im at 24,000 miles no problems.

Im curious though ,Has anyone with a bad head been using synthetic oil ?
It might take longer for problem to come up.
I have been using synthetic since the 2nd oil change.

Yea, I've noticed higher mileage H3''s reporting the problem. But so far I've had no problems at 31,000 hard miles.

I have used synthetic oil since my second oil change. Just had the second head put on at 37,200 miles.

fourfourto, I have had synthetic oil since the first oil change around 5000 miles. I have now about 24000 miles and my car will go to the shop tomorrow for the first head replacement. my production date is approx. april/may 2005.

I just returned from the dealership with some bad news.

My check engine light was on, engine was running rough, onstar reported a misfire problem, and the dealer diagnosed the codes which require a head replacement as per the service bulletin.

He ordered the parts, (head, gasket & 16 bolts?) and said the truck would probably be in the shop for a week for repair.

He gave it back to me and will call when the parts arrive. About 10,800 miles on mine w/ 2 oil changes @ 5000 & 10,500 w/ regular oil.

VIN # is below the number indicated on the post.

Add another to the replacement list. 36k miles. 11/05 build date.

Check engine light came on and codes indicated misfire on #4 cylinder. Dealer informed me I was getting excessive blowby on that cylinder. Waiting on a final resolution from the dealer but will likely be a head replacement.
