My 2015 Pro-4X Xterra automatic will not shift out of 4wd Hi... unless I cut the wheel hard right or left while driving very slow. Even if I come to a complete stop and go again the front wheels on the 4wd/2wd indicator just keeps flashing. this is a new problem. It used to shift in and out on the fly with no problem at any speed below 62 mph. This is my 4th 2nd gen Xterra and I never had this problem with the others. Thanks.
