My 2006 H3 also needs a new cylinder head now. Has anyone started anything about this? I haven't contacted GM yet, because I'm waiting to get a cylinder leakage test done in Wednesday to ensure that this is the problem. If anyone has any information, please let me know. This shouldn't be happening on a vehicle like this. Thank you.

I have a H3 year 2006 with the same problem; #5 misfire due to the intake valve seat failure - engine cylinder. It should be a recall on the parts for all H3s to be fixed.

I would definitely join in on a class action suit as I am going down the same road.

I have a 2006 H3 which is also having this issue... I would very much so like to start a class action suit. We should be entitled to a recall. For a car like this, this is ridiculous.

I would love to join. My 2006 is having engine problems and it's Hummer's fault for building crap.
