Well I finally took my H3x in to the dealership to see what that noise is. It only happens when i get up past 65 mph. But the manager at the dealership took it for a spin, and when he got back he said they will take out the windshield and put new filling that they use on the '08 along with putting new marker lamps on it just in case that was teh problem. I'll let you know how it turns out!

 

Just to let everyone know I got my H3 back today and i'm going up the highway at 70 mph without a sound. So they think my windshield had an airleak or something. Moore Cadillac and Hummer in MD does a great job of taking care of their customers!!

 

sweet,i noticed mine did it for like 10 seconds the other day,but quit,i hope it dont come back

 

I have it at speeds over 70. I figured it was the black plastic trim on the "A" pillar. Only seemsto be on the left side though. I was going to fill the gap with black silicone.

Maybe I should take it to the dealer instead?

 

i've been experiencing the same time of airleak sound in my 08, will have the dealer ride along next time I go back

 

Mine just started vibrating over the wekend in the area of the drivers-side windshield, but it seems to startat about 55 MPH, and doesn's change no matter how fast I drivefor a mile or two and then it stops.Think it might be the same thing??

 

Yea could be, I suggest u take it in to the dealer. Hopefully your dealership is as good as mine. The also put all new silicon and marker lamps on!

 

Thus far, Bob Moore Hummer has been very helpful!! Guess I'll see how they do with this.
