Driver assistance
Vehicle aggressively and without cause engaged the Automatic Emergency Braking System causing the driver to be slammed against her seat belt and almost having the car in back of us to almost rear end our vehicle. This has happened in the past but it has been a manageable slight deceleration when going around a gentle curve or at the railroad overpass. . This time the incident was intense almost causing a rear end collision. I would add that this severe incident happened when approaching the same railroad overpass in the rain. This has also happened at this intersection in good weather. Under all circumstances there were no obstructions I front of the vehicle. I have read that this problem has occurred in earlier years of Nissan products. In all instances the appropriate system warning light illuminated.
