Braking system activates when going under a bridge that is casting a shadow. This has happened multiple times
The vehicles automatic emergency braking system falsely triggers under certain conditions. It most commonly occurs when the the vehicle travels under bridges in sunny, clear conditions. Presumably, the vehicle believes that the shadow cast by the bridge is an object when it is in fact just a shadow. After this happened three times in a 20 mile stretch, the vehicle displayed a warning light saying that the system had malfunctioned and automatically turned the forward collision system off. The problem still occurs to this day when driving under the conditions previously described and has nearly caused a number of accidents. The vehicle is available for inspection upon request.

The emergency braking driver assist is panic braking going over railroad tracks. It is "seeing" the railroad tracks as a vehicle and emergency braking with no cars around. The problem is even when slowing to a crawl under 5mph it slams on the brakes. Any car following behind may hit the car as there is no reason for the braking. Any speed going over tracks will cause emergency braking, the safety issue is if going at any speed a car following behind may without warning or reason have this truck stop for no reason. This is a major accident waiting to happen. We ha e reported it to Nissan and now the 2nd service reporting it and they have been "investigating" is for over a year now. Multiple trucks have this issue. The sutherland nissan dealer had a tech see this happen to them. If the road is at an decline, and there are rxr tracks the metal in the tracks are seen as a car. The sensors /software need fixed. The only workaround now is to turn off the front end avoidance emergency braking (so why have it) and if there is an accident insurance will want to know why we turned it off.
