My H3 has hit 63k miles and I started having head issues shortly after hitting 50k. hummer wont fix it and the estimates are over 3000$. it is shuddering violently and I've been on the phone with hummer and they said its out of warranty. seeing how its the inline 5 that is having trouble across different makes and models I dont understand. Any Suggestions? btw heads 2,3,5 are all misfiring, obviously a manufacturing issue. my build date was in 07/05 and the vin starts with a 1.

Excuse me for asking, were you on the planet when GM, the manufacturer of Hummer H3s, went bankrupt this year?? The limit of your claim is warranty, when it's gone, you have nobody to sue, debts and liabilities are discharged in bankruptcy.
Hummer is not going out of business, it is in the process of finalizing its sale to a new company.

No problems since. Now have 65,000. Did get extended engine warranty to 100,000.

[QUOTE=Doc Olds;207545]There is a search feature here, like every other forum I can think of.
The S/Ns affected is any 2006 H3 lower than 287591 .... the first one started with 100,001, your truck build date will be Nov. 06 or earlier. Not all have the problem, but some could. The head issue affected not only the I5, 4s and 6s were subject to the same issues.
