I Love when the service department a) changes the rules as they go and b) know nothing of a on going head issue. They had been real good abou tcoming to pick up my H3 from work saving me an hour drive and having to take work off but he said they changed thayt rule just this morning...

I then asked them of they had any ideas and they said it is probably just a plug wire. I asked them about any one else having trouble with the head and their answer was, we have never even heard of that. I asked them if they have any one that follows any of the HUMMER fourms and he said that there would be no reason to do such. I guess no one would benifit from keeping the pulse of teh owners

Thats sucks man. Sounds like Cerritos Hummer. You should print out some of the forum transcripts of all the head threads, for them to read. see what they say. Good luck brotha!

They haven't heard about the head problem? My dealership service department discusses it freely without me even bringing it up.

if it's the misfire just work with onstar, they will arrange a tow to the dealer via Hummer roadside asststance and you get a rental at no charge. Educate your dealer if this is the problem. when rental charges are racking up things start to happen.

Welcome to the head club. I traded my 06 so hope it went away with that.

Plugs wires - the H3 doesn't have plug wires. I forget the proper name (maybe coil on plug??). The coil connects directly to the plug.
