I have not received any VIN information from you, so let's get that straight. Plenty of other people here have emailed me or sent private messages, so that is not the problem. But just in case, here is my address

Now, as for the cylinder head, to my surprise it is serviced as a bare head (why they do this amazes me). So, the dealer tech has to assemble with new valves, springs, head, etc., if the entire assembly was returned.
If there is this problem you are saying, the engineers would want the head back all in one piece, they would check it out. If nothing comes of the checks, they might have it installed on a test vehicle and driven to see if they can verify the original problem.
As for you, the take a logical view of your original post, and the mentions of recalls, the high number of vehicles (for one dealer this is high), and your now infamous last sentence, then you could draw the same conclusion that the rest of us did in the beginning. It looks like a troll post; especially since it was your first post.
We have quite a few trolls hit this website, as do other websites.
As for problems, from what I learned today, there is no large problem with the head. As in anything man made, some will break, some calibrations will go haywire, etc. This is not to say there won't be a problem in the future, but from what I learned today, the labor op for head replacement on this vehicle is very, very low. And labor ops are the main trigger for a problem, other than TAC input.
But TAC is not that reliable, especially since they are a contract firm, and not GM employees. In addition, there are NO preliminary investigations at this time on cylinder head issues on the H3 or on any other vehicle using this engine. A preliminary investigation is initiated by TAC to get info out to the field.
So, whether you send a VIN or not, is up to you, but stop saying I have it, because I don't. Personally, I have decided this thread is no longer any more fun, or informative, so since
I'm out of here. My dog wants to go play in the snow.
