Hello Everyone thank you helping me out. I went to Firestone and they say my 2006 H3 troublelight is low pressure in cylinder #3. "Take it to a dealer because the heads have been subject to a recall." The dealer knows nothing about a recall for the H3 heads (of course) and I cannot believe Firestone would make this up. I know the heads are used on other models then Hummer could the recall be engine specific and not Hummer specific or something? A company recall and not a federal recall? I read a couple of blogs that say the valve springs were bad that year and subject to recall but nothing concrete. Any advise would be helpful.

 

Do a search on the issue on this forum and you will find out everything you need to know about the head issue including the VIN Numbers involved. Happy hunting.

 

Rk I did an inital search for "H3 Heads" and came up empty. I then tried again "Heads" and found one thread...any other links you might have would really help!

 

You can search here for recalls for your vehicle.

Vehicle Owners | Safercar -- National Highway Traffic Safety Administration (NHTSA)

I think the only one I have is for the hood and I didn't want glue all over my hood.

 

thanks guys you are awesome...yeah the only federal recall is for the hood...but I thought (dreamed) that GM might have some voluntary recall on the heads...RJ is right, there are many complaints about them-bad guides not springs like I first thought

 

On this forum, go to the Hummer H3 section. At the bottom of the page there is a section that say "Display Options" Unless you changed the last item there, you only searched the last 2 months. There was never a recall as GM figured the defective heads would show up under warranty due to the weight of the vehicle. They did give some of the lighter Colorado/Canyon owners with the same engines a 100,000 mile warranty but not Hummers. As you will read, some were replaced after the warranty ran out but on a case to case basis.

 

just out of "motorhead"curiosity id like to know specifically what goes wrong mechanically when the head is defective. ive heard guesses

 

I saw my old head, the valve seats were worn away. The valves were sitting so far up in the head.....

 

I discussed my recent experience here the other week
