I am shopping for an h3 but concerned about the valve seat/head issues i have heard about. Do all years have this issue and is it pretty much guaranteed to happen? Any help or advice would be appreciated.
Thanks,
greg

 

mostly 06, discussed here a million times. do a search and find vin #s
by now most bad ones were probably fixed...

 

The answer to your question regarding ... paranoid misinformation ....

From an almost 10 year 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.

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."

There are I5 H3s, Colorados & Canyons out there chugging along with 300k miles on the ticker.
