What owners say
while i was driving, the front collision warning and emergency brake went off out of nowhere when there was no cars in front of me as the street was empty.
Collision mitigation goes off all the time in the rain when it’s reflecting, the brake light of the car in front of me on the road which caused my car to slam on the brakes because it automatic emergency brake
Forward collision warning light came on as I was driving w/ no cars in front of me. The car jerked as if i slammed on my brakes. As I was pulling into my driveway, Malfunction See owners manual showed along w/ AEB warning light. I waited a while then came back outside to start car and the brakes were stiff and it wouldn't start. Malfunction see owners manual showed again along w/ AEB warning light and Engine light blinking. Then it started to make a constant, solid beeping type noise and shut off. I literally just found about the recall as I never received any type of notice. It took Google to tell me this which brought me here.
The contact owns a 2019 Nissan Sentra. The contact stated while driving 45 MPH and exiting the highway, the Forward Collision Avoidance Automatic Emergency Braking feature engaged inadvertently and the vehicle stopped abruptly, causing the vehicle to fishtail. The contact stated that an unknown red warning light was illuminated. The contact stated that there were no other vehicles nearby at the time of the failure. The next day, the contact notified the dealer of the failure and made an appointment to have a diagnostic test performed. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 56,000.
Even a small bump in the road (not even a big speed bump) sometimes causes the front bumper to rise and strike the bracket holding the forward collision warning sensor. That throws the sensor out of calibration and makes it unreliable. The tech at auto nation collision in las vegas told me this is a common problem. He said the bumper and the bottom of the bracket are too close together so the bracket gets hit often and damages the sensor. This is a safety issue. You think you have a collision waring system but you don't or the sensor reports a collision when none has happened.
My car frequently chimes with the forward collision warning / emergency brake assist as though there is a chance of a collision. When it does this, there is absolutely nothing in front of my car! When leaving work 2 days ago, I started to cross a little bump in the road that I cross daily with no issues; this particular instance however, my car decided that it was an apparent collision because my car came to a dead stop from about 15-20 miles per hour. Fortunately my husband and I were both wearing our seatbelts, and no one was behind us as it would have certainly caused an accident. The sensor/radar for the forward collision/emergency brake assist is a hazard in my opinion. The concept is fantastic, but if it's not going to work properly, then it needs to be removed from vehicles, or at least be able to be disabled indefinitely, not just while you're operating the vehicle only to have to remember to disable the function next time you're driving.
Front radar collision warning active, it does not slow or stop the car in event of obstruction.it goes off every time I start the car and within 5 minutes of driving it fails and deactivates the auto stop function.
