Brake Sensor problems of the 2016 Nissan Rogue

2016 Nissan Rogue sl awd forward emergency breaking system gives warning when there is nothing in front of the vehicle. This happens sporadically, day or night, wet or dry atmosphere, and at multiple locations (straight stretchs of highway, 4 way intersections, stoplights, railroad crossings, bridges/overpasses). It has been taken to my local Nissan dealership where I purchased the vehicle multiple times as well as another local Nissan dealership expressing this issue. I have been told that my sensor was bad so it was replaced and the codes were erased from the system. This issue still happens after that repair. I have been told by service advisors that it's because the sensor is dirty or it's something that just happens. I have contacted Nissan consumer repair who state they are willing to work with me but they only keep my car for a few hours or a day and have a technician drive it to duplicate the issue with no success. I have been told that if they cannot duplicate the issue then there is no repair for it. I understandt that but, I am scared that it is going to actually activate while I am traveling to and from work on major highways at high rates of speed. My "I thought it was safe based of safety features vehicle" does not feel so safe anymore. I will not let anyone ride in the vehicle me out of fear that I may cause them harm with this issue.
