If you tried the above below is my experience and what cured the NAV.
I had problems for a long time with my '14 Limited. The problem was the TMC avoidance was on for one or more items including traffic. You have to find this under nav/settings/guidance. There are a few settings that will reroute the jeep based on traffic, even if the traffic isn't really obvious. Once I turned those all off I regained control of my NAV.
This of course assumes you have this feature, otherwise can't help you.
