The transmission would occasionally slip while in motion during acceleration. When the vehicle was brought into the dealer for an oil change, we brought the issue to their attention. Service department advised that a tcm software update was needed. I located a service campaign bulletin covering tcm reprogram covering 2013 vehicles (sb-10051662-4475). Nissan consumer affairs will not address the 2014 issue at this time.
