Hey Guys
I'm noticing a vibration in my new 07 H3. it happens between 45 and 55 mph. I can feel it on the floor and through the gas pedal. If I remove my foot from the gas it stops. There is no noise, just a tight vibration. It goes away above 55 mph. I noticed that the transmission shifts at about 45 mph. Any help? I'm planning on taking it to the dealer this week, but I would like to go in there with a little knowlege. Thanks

 

Have you checked out this thread yet? Does it sound like this? https://www.hummerforums.com/m_67824/tm.htm

Thanks for posting that link. I did read that earlier when I was doing a search on this. I don't think I have the same problem. This vibration almost feels like a buzzing. I don't know if I'm describing it right or not. My first thought was that it might be a motor mount.
