I just scanned over 35 H3's in Rochesters Hummer Dealership and I did not see any Roof Dents on any HUmmers (H3'S). I was on the Hummer Roof with the owner of the dealership and he stated he has not had any Roof Dent issues in any of the 143 H3's the dealership has Sold. Sorry-Peter

When I picked mine up a little while ago I looked over some of the H3s they had on the lot. Was hard to tell without going around and climbing up on each one which I didn't have time for. From what I could tell, looked like about 80% of those with sunroofs had the dent but none of the ones without did. Again, it was hard to tell from the ground while the sun was starting to go down.

Not trying to imply in any way that the owner would lie about it but I would be surprised if 10% of the people that have the dents even know they are there let alone the dealer. That is cool that you were able to go on the roof and check the lot and from what you could see none had them. That is just about the only way you are going to see it. Wonder what is causing it. Like someone said, could be happening on the transporter but I think it has something to do with the sunroof and/or it's install.

I agree :-) so I have contacted the Hummer Mechanics from the shop. Since I have bought 7 Hummers in the past few years from the dealership I have had a great relationship with the Mechanics and so far no one has had any Roof Dent issues. However I sent an email to a few more friends of mine at 3 other dealerships to look for the issue. Please note that out of 35 H3'S only 11 were sunroof models. I agree that this may be a sunroof installation issue.

Let us know what you find out. This isn't something that I am ever going to worry about getting fixed but I just started to get curious when I saw another with the same dent yesterday. The only reason I noticed it on mine is because the back door I use at our office overlooks where I park. When I looked at it up close yesterday, I couldn't even see it, though it was covered in pollen Maybe that is why nobody seems to be noticing it. I just assumed it was just something that happened to mine until seeing that one. It is strange though.

Just sent a few photos to the quality folks working on this project. I'll let you know what i find out. Probably won't do any good for those of us with the dent, but at least they'll stop from happening for future buyers.

Just saw another H3 sitting outside with the same dent. This one doesn't have the sunroof though.

Sounds like the sunroof installer sits his fat axx on roof while working on it.

Re: Roof Dent
 

I wonder if it's also temperature related. If the roof gets hot and wants to expand and the glass sundroof installation won't let it. Maybe on a cool day it goes away. Just a thought.

Re: Roof Dent
 

I noticed not so much a dent, as a subtle warping when it sat in the driveway, i chalked it up to the heat on the black metal, it goes away when it cools off.

The fat sunroof installer got my vote!
