With you being there and me being here all I can do is ask a few questions.
Does your vehicle have redundant steering wheel controls - radio volume etc?
There is a ribbon inside of the assembly that feeds power to those controls, that is usually what goes bad and makes the squeaking noise.
Yes it is nice to get things fixed while it is still under warranty, but when the design is poor and even if they replaced the ribbon assembly, in about the same amount of miles as when it went bad the first time, it will go bad again.
The worst part about working on those vehicles is the Air Bags.
Once the wheel is off, the repairs is not that hard to do.
Might I suggest that you find a good local mechanic who is good at repairs on new vehicles and is reasonable. You are going to need his services more then once in the next couple of years, if you plan on keeping this vehicle for any period of time.
I would not suggest that you try to repair this on your own unless you have the proper tools and equipment and a through knowledge of mechanic's.
About the only other thing you can do is buy a used steering column and take your chances that it won't do the same thing that this one is doing.
