I have a 2010 limited with 27K on it and the noise was light at idle louder at highway speeds 60-70mph noise came from the primary took it to the dealer and they could not find it to start with so they threw parts at it until they fount it come to find out it was the cluch bearing so I hope this will help someone else on the good side of the coin I got all the up grades in my primary thanks to HD waranty.
