For earlier Pathfinder model years (2005-2008), a defect in the radiator allows engine coolant to leak into the transmission. However this defect doesn't appear to affect Pathfinders from 2009 & later. Nissan did include the 2009-2010 models when they extended their radiator warranty on 2005-2010 Pathfinders to 8 years/80,000 miles in response to the transmission defect.
heat would not blow warm when idling or in neutral
I have a 2009 Nissan Pathfinder SE with ~90,000 miles. Bought it in late summer 2015. When winter hit, I noticed that the heat worked great when driving but would blow ice cold when idling at a traffic light or when in park. Repair folks said it had an air bubble in the system. The bled the line and now it produces 140 degree heat. Cost me $50.
