2014 Nissan Rogue electrical system problems

Vehicle was being parked. As driver applied brakes, vehicle accelerated forward, jumping sidewalk curb and collided with tree at approximately 10MPH. Engine continued to run, driver managed to gear to reverse and backed vehicle away from tree, off the sidewalk, back over the curb, and into parking slip. The manual supplied with the vehicle claims that it is equipped with event data recorder capable of storing information prior to and during an accident. Dealership claims the vehicle is not.

I have qty 2, 2014 nissan rogues, both have the $1420 navigation system and neither of them work. The directions are not accurate and can be off by miles, or just out of the area altogether. It will not display sub streets and just tells you to get to a main road. The nav, radio and control module reboots often. I have had the dealer look at it and in one of them they upgraded the maps data file, this did not help.
