I noticed a ton of posts on this issue.
Is there a particular year, VIN number, model to avoid?
I notice there are STILL several 07's and 08's on my dealers lot!

 

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.

I do know of a couple people that had a bad valve spring with 07s and even an 08, but those are extremely rare.

 

I just boughta 2006 H3. I believe it was an early one. How do I know ifI qualify for therecall or extended warranty for the head issue that you mentioned above?

 

Anyone?

 

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.

Read this: Head and Valve Problems.

Good luck

 

Thanks for the reply. Well my H3 vin is below the mentioned above so it looks as if my H3 might have problems down the line. I have been reasearching the thread you provided the link for. However it seems as if the extended warranty coverage and length differs from member to member.

How can I find out what kind of extended warranty coverage my H3 heads have?

 

I have a early March 2006 production H3 and have had the head replaced twice. They would not give me any extension to the factory warrenty.
