In most cases, Both to your last Question Mikey..

 

Mikey, I think the issue effects some differently. As I have stated in previous posts (much to the disbelief of some) I NEVER had a check engine light come on in the 2000 miles I drove it on my roadtrip which is when it happened. I got the OnStar report email containing the warning, a constant rough idle, and when I called OnStar to run a diagnostic, all they could say was it showed an "engine misfire code and an emissions isue."

 

Yup. I remember you saying that. That's why I asked. I have a feeling I may finally be coming down with it, which doesnt make much sense considering mine was belt after the supposed date range. I would like to just blow it off and say it's because the new built may be slipping, but I've driving almost 1000 miles since then and I think that's more then enough for a new belt to wear in. I'll put the OBD scanner to it later tonight and see what it comes back with. That's ALL I need now right

 

Mikey, your little Hummer isn't a hypochondriac is it? Boy, you and Killer seem to have the duds of the bunch eh?

 

Yeah, but keep in mind, we also drive our H3 more the probably anybody else on this forum. In 16 months I have put 30k miles on it. That's ALOT of driving. If anybody we are the test dummies lol. I take immaculate care of my vehicles I own and notice things most people wouldn't, and 99% of the time I'm right on the money with it comes to discovering and diagnosing repairs. With the exception of this on-going differential issue, I've been right every time. Now that I'm driving 100 miles a day to and from work, I'll really be working this baby lol.

I'll have to post a follow-up later and see if I'm getting any codes back. I surely hope not. At least I can bring it in to HummerMike now. I'll probably be his first customer lol.

 

I made a mistake. Mine was manufactured in Oct. '05.

 

See my latest post up above under warranty contact info [:@]

 

Yes. Very disturbing. Real NICE customer service. And then people wonder why Imports outsell American cars.

 

Well yes, they aren't going to give anyone anything that has not had this problem.

 

I'm not trying to be a pain but GM will take care of everyone. Everyone just relax,it will all work out.
