Count me in on this noise also. I have under 600 miles on mine and it bugs the crap out of me. Plus I live in Palm Desert where 110 degree temps are normal . I came from Mercedes ML so I assumed things would feel a little cheaper in a GM car but this rediculous. I'm glad it's not normal. I will watch this thread and wait until the updated part is available before I bring it in.

Just bought my '07 H3 Lux on June 30th, already have noticed the problem with less than 500 miles on it. Thank God for this forum, I thought I was crazy imagining it until I saw this post. You guys are great! Sounds like there's quite a few folks on here that bought from Sewell Hummer, guess I'll get in line on the waiting list for the new and improved part.

Hi JC. Welcome to our forum. Yes, there are quite a few members that purchased their Hummer from your dealer.
And, just so you know..........

Mine is doing the same thing. I have an appointment on Saturday morning to have mine checked out.
How can you tell the manufacture date? And what production dates are having the problems?

You can find the manufacture date on the manufacturer's sticker on the driver's side door jamb. As far as I've heard, it's been all 07 H3s. There was a slight model change this spring where they moved the window switches further up the door, along with a few other changes, but I doubt they changed the steering. They did announce a big change to the steering for the 08 H3 lineup.
My dealer got the part in today; I have an appointment for August 1 since that's the earliest I can get in.

I just talked to the service advisor at Sewell in Plano and he said they are starting to get the new replacement parts in. I got on the list, he said probably about a week until they get to me.

I took my h3 in for the rattle also.....at first they could not find the problem.....I had to go there myself and take the service manager for a ride......It finally made the noise. They called me yesturday and said it is a bad drive train and it needs to be replaced.....funny thing is, if they know about it, why would they say at first that they did not know what the problem was?......that pissis me off more...........just like my old truck, toyota tundra, there was an issue with the brakes system, and they tried to charge me. Lucky i found a forum like this and it talked about a recall for the brake system.....printed it out and took it to the dealer...........hes like umm.....this is the first i heard of this.........dumb a$$e$

I moved my appointment up from Aug 1 to yesterday.
I think I got the “early” fix for the clunking in the H3, mostly because 40 minutes after I left the dealer on a 100 degree day the clunking had returned, albeit a bit lighter. They left a copy of the service document in the truck for me so I’m retyping it below. I did not get a chance to talk to my service guy. And there's a reference to an updated part number becoming available so I guess I'll be going back in sometime. I'm taking my H3 offroad a bit today so if that issue is there I'll know after some building up lots of heat offroading in the desert.
Document ID# 1993018
2007 Hummer H3
Subject: Clunk or knock heard and felt through the steering wheel or brake and accelerator pedals – keywords intermediate rattle shaft #PIT4448 – (06/27/2007)
Models: 2007 Hummer H3
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern A clunk or knock noise is heard and felt through the steering wheel or brake and accelerator pedals, the cause is a slip/stick condition in the lower steering shaft. This is a temperature sensitive issue and usually requires the vehicle to have been driven for a period of time to increase under hood temperatures.
Recommendation/Instructions Replace the lower steering shaft part no. 25776339. There is a high probability that replacing the shaft will correct the condition as there are only a small percentage of parts that exhibit this condition. This PI will be updated when a new part number becomes available. And then some GM mumbo-jumbo at the bottom.

Mine was mfg 1/07. I do not have any noise at all, brake pedal is fine, but........... I did notice on a few hot days in the past, when on a cement roadway, when you go over the joints you could feel a click every joint in the gas pedal. Thought I was just freekin out, started to drive with my pinky toe lifted up while on the pedel, really thought maybe I was imagining it? Didn't think too much of it until I read this thread. When GM does whatever it is that they do to deal with this I will be in on it. Pretty minor now, but only could get worse if I do nothing. I have 5575 miles and just noticed it the end of June here when we had a heat wave. Been prety cool last couple weeks so has disappeared lately. Gremlins can come and go, but seems we are on to this one.

I took mine in today and the service manager said he call the Main Hummer service officials and they said they did not know what the problem actually was and that there was no fix for it yet but they are working on it. Seems we are getting conflicting answers from various dealers. My service tech said he thought the noise was coming from the shaft hitting the firewall causing the feeling through the brake and gas pedal. Well, anyway, I have it documented that there is a problem and will be on a list when the fix is in. He said there were no safety issues which is a good thing. Mine was produced 09/06.

It's amazing just how clueless some of these dealers are. Not only that some seem to have no idea what's going on, but that they're wasting their (and their customer's) time attempting to fix the issue w/o NEW replacement parts. Replacing with the same parts does nothing, as the current steering shaft assembly design is faulty. Thus, until a NEW design is implemented, how can they "fix" it? Crazy.
For anyone watching this thread, here's what I know. My dealer seems to be on top of it as best they can. Which is to say that they, like everyone, are basically waiting for the new steering shaft assembly before doing any more "repairs". Initially, GM had stated that dealers should start receiving the new parts sometime this week, but that appears to have been pushed back. Word has it that the new assembly is being tested and, barring any unforseen issues, will begin to be produced and distributed in the coming weeks. Unfortunately, no one seems to know how long exactly.
DO NOT waste your time having the dealer look at it or attempt to fix it. If they are aware of what exactly is going on, they should be putting everyone on a list to notify you when the new assembly is in and schedule your service.
If they seem clueless (which would be baffling at this point) as to what is going on- point them to this thread and tell them to get on the ball.
Hope this helps for some that are not getting helpful info from their dealer.

I'm still waiting as well. DOH! At least I got a step further, and was verified that I had the problem  Granted, it's nowhere near as bad as you folks, but it's there.
