What owners say about the forward collision avoidance

Verbatim from NHTSA complaints, newest first
“The contact owns a 2020 Nissan Altima. The contact stated that the auto-braking system unexpectedly activated, and there was a grinding sound coming from the brakes; however, the vehicle failed to stop as needed. The ABS warning light was illuminated. While driving approximately 60 MPH, the brakes suddenly activated, and the instrument panel illuminated with a vertical yellow light. The vehicle was pulled over to the side of the road and waited for a while before restarting the vehicle to continue driving. The failure reoccurred the following morning while driving 35 MPH. There was no warning light illuminated. The vehicle was pulled over, turned off, and restarted to continue driving. The failure had occurred approximately 5 times. The contact stated that with the cruise control set to co-pilot, the steering and lane assist features failed to operate as intended, advising the contact to manually steer the vehicle. The failure became more persistent. The vehicle was not taken to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 120,000.”

“I was leaving for work, backing out of the driveway, and the brakes just locked up out of no where. I’ve done this multiple times and the brakes have never done this. I tried pulling up and trying again, turning the car off and back on, and backing a different way out of the driveway. It kept locking up on me and nothing was in the way. My husband had to eventually take me to work. The automatic braking system failed. I’m not sure if it is available for inspection upon request. At the time, my safety or anyone else’s safety was not at risk. I just worry about if it happens while I’m driving on the road. That could defiantly not only put me at risk but also other drivers. No the problem has not been reproduced or confirmed by a dealer. It just happened this morning. The vehicle has not been inspected. No warning lamps. It did pop up the car with the 3 blocks in front of it on the screen like I’ve seen before, prior to failure, but not the warning about the automatic braking system.”

“THE VEHICLE HAS ACTIVATED A FALSE AEB ON SEVERAL OCASSIONS SINCE I PURCHASED THE VEHICLE. I IMMEDIATELY TOOK IT BACK TO NISSAN AND THEY STATED THERE WERE NO RECALLS AND THE VEHICLE SEEMED TO HAVE NO ISSUES. I'VE HAD THE VEHICLE FOR 5 YEARS AND IT CONTINUES TO OCCUR, NEARLY CAUSING A TRAFFIC COLLISION. TWICE THIS YEAR, THE VEHICLE MADE A COMPLETE STOP ON THE HWY AND TOOK A MINUTE BEFORE I COULD RESUME DRIVING.”

“The contact owns a 2020 Nissan Altima. The contact stated while driving approximately 50 MPH, the vehicle lost motive power. The contact stated that the message "Engine Malfunction" was displayed, and the check engine, traction control, and Forward Collision Avoidance warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the mass air flow sensor needed to be replaced. The vehicle was repaired but the failure reoccurred days later. The vehicle was then taken to an independent machinic where it was diagnosed and determined that the battery needed to be replaced. The vehicle was repaired but the failure persisted. The contact stated that the battery was replaced three additional times by several independent mechanics; however, the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.”

“This car is going to kill me! It randomly hits the brakes on the highways! I am literally driving a deadly weapon. I turn the emergency brakes off and had it checked and STILL brakes. It break everytime I pass a shade spot on the road and even highway going over 60 miles per hour! It hits the breaks while I am in traffic making the driver behind me almost hit my car. It breaks whenever I go under a tree. It breaks when I am in a parking garage when there are NO cars around. It breaks randomly in traffic with no cars too close by to create a collision. It breaks in front of a school bus that was driving close behind me. It hit the breaks going 30 miles per hour. If the school bus would have hit me then that would be child endangerment. The bus driver thought I would break checking him but it was hard to explain it was my emergency breaks. It’s been getting so bad that I am writing a complaint until something can be fixed or changed. It’s ruined my breaks in general from always setting off the emergency breaks. It is not even emergency breaking, it’s breaking to kill at given moment. It’s ruining my car and my ability to drive! This is not correct and it’s keeps…”
