I have the same noise in my 2011, its so annoying. I took it in to the the dealership and they said they adjusted the "column finisher," whatever that means. But guess what? They didnt fix a god damn thing cause as soon as i got back in the truck and turned the steering wheel...clicking... clicking left...clicking right... so what did they actually do except bill nissan for an hour on something they didnt fix. So now I have to go back and lose the truck for another day. I personally think its the spiral cable getting hung up on something behind the steering wheel, but what do i know..
