I'm having that same sound on my 2011 2LT ... reminds me of a hamster wheel ... sort of a wobbling whiney noise. Is it a known issue?? Thanks for posting that video, I had been trying to explain it to others ... this video is spot on with my noise. Not sure where to find a good dealer to take it too though. I've asked around a bit, waiting for some recommendations.
Update - have a monday morning appt to have it looked at :-)
