I'm not trying to slam the X3 but I have my third or fourth different X3 loaner and I noticed that every window squeaks and creaks. Every bump or road imperfection I go over induces a whole bunch of noise. It sounds like the windows are all loose even though they are all rolled up. It actually sounds like rattling. The X3 I am in is a 3.0, non-sport, with only 3350 miles on the clock. I haven't heard this noise from any other X3 I have driven. Is this a common problem?
