Nissan Faces Class Action Suit For Vehicles That Brake For No Reason

A U.S. District Court judge will allow a class-action lawsuit to proceed against Nissan North America over what owners claim is a faulty Automatic Emergency Braking (AEB) system, reports CarComplaints.com. The lawsuit includes all 2017-2019 Nissans with AEB systems and alleges that the systems sometimes brake for things that don't exist.

AEB systems are there to alert drivers of a possible imminent frontal collision, braking if the driver doesn't respond to the warning by putting on the brakes themselves. Nissan's AEB systems use radar to determine pedestrians, other vehicles and other potential obstacles ahead of a car, and owners have complained of it malfunctioning while driving the car.

I have a Murano & recently returned a leased Maxima. The Maxima didn't have the radar-based AEB system.

However the 2018 Murano required 2 separate repair visits for the same malfunctioning radar component.

The auto cruise control, front collision detection, & AEB would suddenly "disable" while driving. The indicated error message: "Front Radar Unavailable Due to Obstruction" would either display or the corresponding indicator light would come on. The system would disable at random times, with no apparent cause - while driving on city streets or on the highway on a clear sunny day. If you were using cruise control, the system would drop out of the set cruise speed but not brake. And can only be reset by stopping & restarting the vehicle.

the Nissan dealers would initially say that the radar module was "blocked" by debris (leaves, dirt, snow, ice, etc. & tell customers to return when the error message came on again. now, they seem to know immediately what the issue is & will replace the radar sensor. but in some cases, the sensor may not be "aligned" correctly. and if your vehicle is out of warranty, it's a $1000 - $1500 repair bill to resolve.
