I would have to say that this concern is on too new a model for us to be very familiar with. I would definitely recommend a dealership look at your concern; show them first hand in the service drive what you are experiencing, perhaps ask for a tech to come witness it. This will help them pinpoint your issue, and solve your concern -- while under factory warranty!
Actually, as I'm doing some research, If you have an ALL WHEEL DRIVE version, it looks like TSB 10-22-4 may apply. It describes:
"a shudder/chatter/vibration driveline sensation during a tight turn, or a thump/clunk noise on light acceleration. These symptoms may also occur under 40 MPH on tip-in, driving uphill, or towing under heavy acceleration."
Suggests a defective PTU (Power Transfer Unit).
