Not a vibrating sound but my drivers door weather striping creaks and squeaks like crazy. Almost like the door hinges are loose and the door is moving.

 

My cupholders drive me nuts when down and empty also lol maybe one of us should figure out this problem too haha

 

I love my Ram, in fact the only complaint I have about it is all the damn plastic that was used on the interior. Seems like you have to go over bumps with the utmost precaution or else the cab sounds like it is going to fall apart around you, the rattles that every panel makes is horrible. My mom bought a brand new '08 Sebring when they first came out and for a "luxury" car the amount of plastic that gets used is down right disgusting. From what I understand the new Rams have really refined the interiors but I've never been in a new one to see for myself the differences made.
