After talking to Mopar.com they confirmed at present there are no Mopar splash guards available for the 2015. The part number for the 2014 does not fit. The front splash guard for the 2014 does fit the 2015. Just an FYI for anyone with a 2015 wanting Mopar splash guards. Below is what they sent me:
