I too recently noticed a clicking noise on what seems to be coming from the front passenger side as best I can tell. It is more pronounced driving in L and when starting off and when letting of the peddle say up to 5mph say when driving through a parking lot. In D mode doing the same it is less prounced sound wise. Once driving, I don't seem to hear it. I too am wondering what to ask the dealer to check and avoid getting milked on nonesense for my 2014.
