Hazard Flashing Warning Light Unit problems of the 2014 Nissan Altima

Since the first week we owned the car, occasionally the screen(back up cam, radio. . . ) doesn't start, or fails within first mile of driving- maybe 10 times since purchase date. On July 29, 2015- morning- car upon start, no screen and no dashboard. Restarted twice and then fine. At 9:30 p. M. Same day-- close to home, side mirror failure warning showed on dash- and a subsequent failure of systems- including but not limited to- gps, screen, turn signals, headlights,hazard lights, all dash information. I pulled into parking garage and attempted to open window to use key fob for gate and had no operating windows, including sunroof or locks. Put car in park and could not get it into another gear. Trapped in car for 15 min. With car running- passenger door then unlocked. Aaa called. Car ran for 3 hrs. Aaa disabled the electrical operating the fuel pump. Car towed to cochran in pittsburgh. Since a restart resets the computer, no code on diagnostic would be found. Cochran considers the situation resolved. Nissan has a case # and several recorded (by Nissan) conversations have occurred with regional rep. And that rep. Will not send written findings of investigation (check the I key)as it is internal information and I will pay all diagnostic fees associated. Rep has no technical knowledge and has no explanation of what an I key is or how or for what it should be checked. There is a directive from Nissan regarding this problem as told to me by wright Nissan, but again nothing will be done without the code from diagnostic computer. This can't happen again- but it will and it could be catastrophic-the intermittent, random, systematic failure will happen- the extent and order of events unknown - leaving us an uncertain outcome and no plan for response in the given situation. We suspect the problem is the bcm as alerted by the internet research, the aaa driver and the cochran tech.
