During random driving the forward collision sensor comes on stating that forward collision is unavailable. Sometimes the sensor will go off 1-2 times or up to 6 times in one day. This sensor controls the (aeb) automatic emergency braking. Nissan has acknowledged this issue in several cars but no recall has been issued. This vehicle is my work vehicle and my personal Nissan pathfinder has already had the part replaced with less than 10,000 miles. Currently my vehicle is out of warranty and they want $1700 for repair of faulty safety parts. I've been driving in perfectly sunny days, on bumpy back alley, just driving on the highways and the sensor goes off. I believe that this issue is more widespread than they acknowledge. Our fleet of company cars are experiencing the same problem with the rogue, Altima.

This is an issue that has been continuously happening since I purchased the vehicle with about 2500 miles on it, it currently has about 6500 miles on it. The emergency braking system continues to turn on and off at various times but has continued to get worse over the few months that I have owned it. The worst situation I have had was recently on a 300 mile round trip when the emergency braking would activate and deactivate every few minutes, in which it would flash on the dash saying the system was obstructed, and the warning light showing it deactivated would turn on, the cruise control would shut off and a keeping sound would turn on. This was happening with no apparent particular incident. The trip took some back roads, a lot of highway (2 lane and 4 lane) and a moderate in city driving. The weather was clear, the sun was out with partial clouding, it was around 40 degrees outside, the roads were dry, some were rough some smooth, other than in the city there was little stop and go traffic. The worst incident was during the return trip, we were on a 2 lane highway that was pretty smooth. There was no one in front of us we were doing approximately 70mph with traffic behind us, we had the cruise control on and were just going along a straight flat stretch of road when the system once again deactivated, beeped then reactivated and beeped and then slammed on the brakes on us. It was only an instant and created no situation of danger based on our position, and as it was instant I was able to step on the gas again and we only dropped from 70 to about 50mph in the period. This was the worst situation I have run into with the issue so I looked it up on the internet and found it is stated as an issue on the Sentra. This unexpected deceleration on a freeway could have been a devastating accident.

After hitting breaks many times and slamming them the car would still not stop

While driving during rain conditions, the forward radar repeatedly disables itself with an "obstruction" warning, which also disables the automatic emergency braking function. This issue does not present during dry weather conditions, and does not happen while transiting through a car wash. This problem was first noted in October 2018 when driving in rainy weather for the first time. The vehicle was new, with 00004 miles on the odometer, at the time of first possession in May 2018. As of 1-10-2019, the odometer reads 14970.

The front radar aeb keeps going out, almost the reason for my vehicle to not stop in an emergency situation. This feature was the complete reason I bought it now I feel like it is dangerous. I am considering asking for complete buy out of my loan. I have taken the car back 3 times in 3, Nissan has no answers other than keep replacing faulty sensor with more faulty sensor.

Car would not brake and hit a pole. The vehicle is supposed to have emergency brakes, but did not work. Often would get a message across my dashboard saying it was unavailable.
