Driver assistance reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

So on October 1st, my car, my nissan Leaf went into turtle mode for the first time. And then yesterday, while I was on the highway, it went into turtle mode, dropped down to 50 miles per hour, and I got off the highway, and the car wouldn't move anymore. I had to turn off the car, wait a couple minutes, and turn it back on, and then it worked again. I was told to contact the dealer to get a car rental. The dealer said that they don't have any loaners available and that other customers are waiting. I contacted Nissan, and Nissan is using a third party called Morley to handle this, and Nissan's saying that Morley's in charge of it and Morley isn't responding. I have a car that's under warranty and has an approved battery replacement. They're trying to call buy the battery, and Nissan themselves says that they would provide a rental, but Nissan keeps referring me to Morley and the dealer is not providing me a rental. And I have a car that I believe is a Potential health hazard that I need to feel comfortable driving, and I don't feel like anybody's helping me.

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. The second incident was in August or September 2026 when I had come to a stop at a stop sign on a covered roadway just outside a parking garage. As soon as I stepped on the accelerator to make a left turn into the parking garage the AEB system suddenly engaged despite nothing being in front of the vehicle. I have owned this car since August 2023 and have not had any other incidents of phantom braking before these two incidents. I have had no accidents or any other incidents leading up to these incidents. I took the car to Nissan of Bellevue where they could not reproduce the issue. They ran diagnostic codes (none came up), checked the physical brakes and checked the 12 volt battery (not sure if they tested under load). They then said they could find no cause of the issue and returned the car to me.

A recall fix was done for the back up camera about a year ago. That was a national recall for an issue with the system. My car started the same exact issue about 3 weeks ago. No back up camera, pink or blue screen, glitchy. I contacted Nissan about it and it didn't seem like they wanted to make the repair again or fix the issue at no cost. I was wondering if other owners have had the same issue and if you can intervene. Thank you

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.

When backing up after opening or closing the trunk the backup camera flashes blue and green with lines on the screen. It sometimes worked again when the trunk is slammed or the car is restarted. The safety was put at risk because I was not able to see the ground when reversing and there was a blind spot that the camera usually fills in.
