“The Automatic Emergency Braking system on my 2021 Nissan Leaf S Plus engaged erroneously (phantom braking) twice. One time was on a sunny day in August 2026 when I had just backed out of my driveway onto my residential street. There was a person walking well to the right side of the road about 100 feet ahead of me. I had just finished backing out and put the car in drive and stepped on the accelerator when the AEB system suddenly engaged despite there being nothing at all directly in front of the car. …”

“Brakes problem: During rain season the moisture can get into the brake system. When backing up, the brakes feel partially seized, and make squeeze sound. The problem is more serious when pulling the parking brake during overnight parking. Somehow the sound is coming out of front brakes. The sound will diminish after break several times during normal breaking. Forward Collision warning system: The system only alerts driver with deeps and lights on dashboard. It doesn’t enables the brake system to slow or stop the car.”
