Automatic emergency braking (aeb) system warning light (if so equipped) I purchased my 2018 Nissan Kicks in Feb of 2019, and have been experiencing issues with the warning light that looks like two cars colliding randomly appearing along with a message "unavailable front radar obstruction." These warning lights can come on at any given time during the time in which the vehicle is driven, and began shortly after purchase of the vehicle. Weather conditions, etc have no effect on this issue. The warning light/message has come on when it's sunny. It can come on when changing lanes, and not even having a vehicle directly in front of you. I monitored the behavior for quite awhile in order to confirm this was an actual defect. My vehicle is garaged most of the time, and there has been no damage to it whatsoever. After further research, I checked the owners manual then realized the warning light that I have been seeing is actually the automatic emergency braking (aeb) system warning light. The message that appears on the dash indicates a front radar obstruction, or impact near the front of the car as well. These may be two separate issues, but they occur at the same time everytime. I always see the aeb light, and the front radar obstruction warning simultaneously. I have also had problems with the blind spot warning lights randomly appearing, and my back up cam glitching out/freezing in the process of backing up.

The Nissan emergency braking system is giving out false warnings. The system on my car has given me hundreds of false readings and warnings while in motion, mostly on highways and expressways. Nissan refuses to say they have a problem with this. I fear that the system will malfunction and stop me for no reason on the expressway.

Nissan aeb (automatic emergency braking) has a serious issue that could leave people seriously injured that could be fatal. The aeb system sometimes malfunctions on a broad range of Nissan causing them to abruptly stop while stopping. This is only supposed to occur in an accident.

Within the first 300 miles the sensors started to malfunction. The dealer replaced the side sensors. The the front sensor relating to the aeb started to malfunction. I now have 6000 miles on the car it has been in and out of shop with no clear solution to the problem. They replaced the front sensor, but within 24 hours it was malfunctioning again. I was involved in an accident 6 days ago, the aeb did not engage, the sensors did not engage. When this first started (2 days after purchase) it was drizzling, but I was stationary when sensor malfunctioned. It would also malfunction on a dry sunny day in a parking lot. There was no rhyme or reason to the sensor going off or on.
