Gocowgirl, You need to do what doc stated above. Contact GM with your vin# If yours has the right numbers it should be covered. I recently had an issue with my radiator that they did not want to pay for either. You have to stick to your guns. Let them know that they have paid for thousands of other engines with this issue, and do not take no for an answer. You have to or they will walk all over you. They have stiffed a lot of people with the 2006 engine issue and the radiator issues as well because people give up too easily. Stick to your guns and they will fix it. If it is in the right vin #.

From an old post of mine:
"The S/Ns affected is any 2006 H3 lower than 287591 .... the first one started with 100,001, your truck build date will be Nov. 06 or earlier. Not all have the problem, but some could. The head issue affected not only the I5, 4s and 6s were subject to the same issues. Call GM with your vin# and build date (from the sticker in the driver's door jam) and ask.

Just in case you're gonna say, wow they didn't even build that many 3s? The VINs are assigned at the same Shreveport plant building Colorados and Canyons. Their VIN sequence unit #s are mixed in and subject to the same TSB re: the head/valve issue.

The recall and extended warranty was for very early 2006s, those with the 3.5L L52 Motors built before March 31, 2006. That is not to say some 3.7L LLRs have never had a valve or head issue. All the Atlas motors built since 4/1/06 have the new hardened valve seats."

Can ypou provide additioanl details on the extended warranty? I'm looking at purchasing a 2006 H3 with 69k miles. It recently threw a P0300 code that the dealer fixed by replacing the spark plugs. It is not currently displayinga check engine light but it has only been driven ~330 miles since the plugs were replaced. Not sure how long it might take for the P0300 to reappear if the real issue is the intake valve seats.

Oh, and the VIN is lower than 287591 so this H3 is susceptible. A technician at the Cadillac dealer indicated that in the majority of cases, this issue occurs around 20-40k miles. He seemed to think the chances of hitting the issue past 69k was unlikely. Thoughts?

My H3 does fall into the lower numbers, GM is not budging. They will pay for 60%, we can pay for 40%. I have contacted more people than I care to ever talk to, it's disgusting. GM now has a new scale they use, a guideline for warranties Since my warranty was up in June, they feel 60% is fair. Now, I learn I'll have to deal with the radiator as well. Seriously. If I had any idea the H3 and GM was going to be such a pain, I would have never got the Hummer. I am saddens they will not stand behind their product.
