Brakes Failed problems of the 2015 Nissan Leaf

Electronic brake assist failed while driving in traffic, October 9th, 2020. Braking distance was extended and the brake pedal depressed much farther than normal, causing driver to stop car with emergency brake. Emergency lights illuminated on the dash. Errors codes indicate faults with the electronic driven intelligent brake control unit, the subject of safety campaign 16v119000. Subsequent Nissan recall, which applied 3nf9b firmware to the edib, had been applied 5/13/16. Failures re-occurred in cold weather in November 8th, 2020. Problem is sporadic and dealer cannot reproduce. However, a video of the failure was recorded and has been shown to them. Replacement part carries yet a new firmware, 4np3e. This firmware should be made available under the safety campaign if it more fully addresses the problem with the brakes.

Brakes failed to engage when changing from park to reverse. Foot was fully on brake when changing to reverse. Car lunged backwards almost hitting someone in parking lot. No indicators appeared before driving vehicle. Incident occurred again later the same day backing out of garage. Issue appears to be related to secondary battery failing but the brake booster should be on primary power system and not on secondary.

Occasionally, brakes fail to work properly when applied at normal (not abrupt) pressure. Then anti-lock brakes activate. This issues is all over the forums, and many have experienced this. Each time the car was brought in, Nissan says there is no issue. They reset all the lights and return the car. We have pictures of of warning and maintenance lights on the dash indicating a malfunction when this occurs. Then it comes back a few days, or sometimes a month later.

Upon starting my 2015 Leaf, with my foot on the brake, I was able to place the car in reverse; in spite of the brake being depressed, the car immediately began to move. With the brake pedal depressed to the floor, the car continued to move in reverse, until I frantically applied the emergency brake. All dash warning lights became illuminated and the car made a grinding sound, when I stepped on the brake. The tow truck driver had to put car in reverse and use the emergency brake to move the car into a towable position. Per Nissan, the intelligent brake control unit failed and would need to be replaced along with the associated harness. Nissan offered to pay $5,500, leaving me to pay $1,500 to cover cost of repair. This is a significant safety concern that the vehicle can have a catastrophic brake failure which completely disables the vehicle. I am very fortunate the failure occurred in an area devoid of any pedestrians and clear of any moving or parked vehicles. I expect that it won't be long before someone is seriously injured by this failure.

The morning of November 9th, 2018 I attempted to start the vehicle after having been parked overnight in our garage. When I pressed the brake pedal, I did not feel any resistance. After pressing the on button, I felt the pedal resist and vibrate. I heard a grinding sound from behind the pedal and warning lights illuminated for brakes and esc. The vehicle would not start so I had it flatbed towed to the Nissan dealership. They determined the electronic brake controller had failed and required replacement. The dealership and Nissan jointly covered the cost of the repair, to their credit. I am concerned this component could fail while driving and result in a loss of braking force, creating an unsafe situation.

I activated my vehicle by placing my foot on the brake pedal and pressing the ignition button. I placed the transmission in reverse. Immediately after, my vehicle began to move, but the brake pedal went all the way to the floor. At this point my vehicle would not stop and I frantically pumped the brake pedal. After about 5 or 6 feet of distance in reverse, my vehicle finally stopped and I placed it in park. Note: there were no prior warning lights or sounds before the brakes failed. The incident I experienced was a very close call. The parking lot I was located is frequented by many people taking exercise walks. If someone had been walking behind my vehicle when it malfunctioned, my vehicle would have struck them. Moreover, another parked vehicle was just a few more feet from where I eventually was able to stop. The dealership said the reason this happened was due to 12v auxiliary battery failure. I have asked Nissan consumer affairs department multiple times over the past month (email/phone) for an explanation and they have ignored me. I would like to find out if this is a problem that may occur again and/or how it can be fixed. They will not respond to my emails or voice mails. I hope you can help in some way to get information. At the very least, make you aware of this problem. Note: I have not experienced the problem again, but am especially concerned now because Nissan is ignoring me.

The contact owns a 2015 Nissan Leaf. The contact stated that the brakes failed to function while driving 20 mph. The failure occurred without warning. The vehicle was taken to the dealer where it was diagnosed that there was a software malfunction with the abs. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 23,000.

I've only had the car for 2 months, and the brakes have failed repeatedly, once about every 5 days on average. Every time they have failed, it was when I start up the car, and put it in either forward or reverse. I usually pull forward into a parking spot, so I go in reverse much more frequently after starting up, but it has happened when going forward too. This is the failure mode. I start the car, while holding down the brake pedal, and then I put it in reverse. At that point the car starts rolling backwards, even though I'm still holding down the brake pedal. The brake pedal gets soft and when I floor the brake pedal, the car finally slows down and stops. Another way to stop it is to put it back in park, but that causes it to jerk to a halt. Needless to say, this is a scary scenario, and this frequently happens at my kids' school, where there are many kids and parents walking through the parking lot. In addition, the car also has some other problems. It sometimes starts a long uninterrupted beep when I turn off the car to get out. The beep goes on for minutes, and sometimes I see a warning light on the dashboard. Finally, the card completely stopped working today. An error message of "t/m system malfunction" appeared on the dashboard, and I was not even able to put the car into neutral for the tow truck. The driver window did not work anymore. After attaching a battery charger to the 12v battery, I was able to put it into neutral, but not able to put it in reverse or drive, or even back in park. The car had more than half of its battery cells full, so the problem was not because it ran out of charge.

Brakes failed upon starting the car, though I didn't know it when I began to drive the car. I had several error lights come on, but I couldn't figure out what the error was, but then figure out as soon as put the car in reverse. I couldn't stop using the brakes and only got myself to stop by using the emergency brake. I was backing out of a parking spot onto a city street, but fortunately there were no cars parked behind me or any moving cars on the street. I also attempted to drive forward, albeit very carefully, assuming it was a strange one-time occurrence. But the brakes simply did not work. Upon inspecting and repairing the car (after being towed to a Nissan delership) Nissan informed me that the abs brake controller failed.

Tl- the contact owns a 2015 Nissan Leaf. The contact stated that while driving at 5 mph and attempting to park, the brake pedal was depressed and traveled to the floorboard causing the contact to crash into a brick wall. The brakes failed to respond. A police report was not filed and there were no injuries sustained. The vehicle was taken to the dealer where it was to be diagnosed and repaired. The manufacturer was made aware of the failure. The failure mileage was 3,000. Djr.

Purchased a brand new 2015 Nissan Leaf on September 12th, 2015 3 weeks later on oct 5th, 2015 brakes failed on this brand new car while driving in traffic on the freeway. As a result I ended up hitting a truck in the rear end at 55 mph. Inuries sustained in the accident and 2015 Nissan Leaf was totaled. I called this into Nissan and was told there was a service notice for this car for brake failure. This was never disclosed to me and the dealer had not performed this service work on the car prior to selling it to us. Please report and have all brake issues with the 2015 Nissan Leaf investigated.
