Bad head

Read F5's comments above. March 31 cutoff date for the new head design. And I'd say we've seen maybe <100 of these here. There were what maybe 20-30k hummers sold before then (including mine). Chances are small (unless it happens to you in which case they aren't).

Do I worry? Sure, I'm concerned it's gonna go, but realistically if it goes, I call hummer customer service have it towed to the closest dealer, get a rental, have it fixed, call GM get my drivetrain warranty extended to 100k, have a new head, a longer warranty, and get to beat the **** out of a rental car for free!!

oops! my bad! March 31-that's what I get for paying attention!

The extended warrenty I got from GM after I had the head replaced TWICE was only for the engine NOT the entire drivetrain. I asked for them to include the entire drivetrain but they would not do it.

hmmm, interesting since I know other posters on the topic have gotten the entire drivetrain. No biggie though, realistically the only thing you'd need to extend the warranty would be the engine (and I would have asked for the emmissions too, since bad valves may affect the cats if the problem is not fixed for a long long time).

I got the H3 back on Saturday (sooner than promised) and it immediately ran a little hotter than before the head replacement (just above the half way mark instead of just below). Took it back into the dealer this morning, they hooked it up and no codes showed up. The service guy said the new heads are prone to do that and not to worry unless it runs in the red. It's good to have it back and I hope it's a long time before I see the dealership again.
