The steering wheel on my 2007 Tahoe squeaks when it is cold outside. I brought it into the dealer when it was under warranty and they temporarily fixed the issue. They said they took the steering column apart and greased a bunch of stuff. Needless to say the issue has returned and I am no longer under warranty. it really seems like it is the plastic from the steering wheel rubbing against the steering column, but I can't see where. Anyone else had this issue and/or no the best way to fix it?
