2015 Nissan Leaf

Just after starting my car, it began moving in reverse on its own even though the car was in 'park' and my foot was firmly pressed down on the brake pedal. It wouldn't stop moving, even with the brake pedal pressed down, until I lifted my foot completely off the brake pedal and then pressed it again. A few days before this happened, a few lights on the dashboard began randomly lighting up, but none seemed related the braking issue. The battery light was one of them. (I don't remember which other ones light up.) So, I tried changing the 12V battery and that fixed the problem. A vehicle moving on it own when it is not supposed to be in motion and the brake pedal not working at the same time is a very serious safety issue. It is not common behaviour for a vehicle to move on its own when the 12v battery is low. This unexpected behaviour could lead to serious accidents. I did not bring this to the dealer since i was able to replace the 12v battery on my own and it resolved my problem.

I was driving with one passenger going at very low speed. I began to turn into parking area and suddenly the car accelerated at an alarming speed. I applied total pressure on the brake to no avail, it did not override the acceleration. I steered into the back of another parked vehicle. The impact pushed the large heavy vehicle down into a ditch and deployed the airbags for both myself and passenger. 911 was called, Police arrived, tow trucks. My vehicle was totalled, and insurance now has the claim. If this has occurred on a highway or busy city street, many lives would have been at risk.

I was driving down the road and applied pressure to the brakes. The brakes did not respond and the dash lights lit up indicating several failures. It took 15-20 feet before I was able to completely stop. If this had happened on a busy street or freeway, the results would have been catastrophic. The vehicle is currently located a Nissan dealership and is available for inspection.

On Monday, 11/14/2022, while driving at 25 mph in approximately 28 degree temperatures, the brakes completely failed on my 2015 Nissan Leaf and the parking brake light, ABS light and traction control warning light suddenly illuminated on the dashboard. I glided to a stop in the breakdown lane, and while in both Drive and in Park when I pressed the brake pedal to the floor there were odd buzzing/knocking sounds towards the front of the vehicle (where the motor, etc. are located) and a vibration under foot accompanied by a clicking noise similar to that experienced during anti-skid braking. I turned the ignition on and off several times but the system malfunction was still present. I was able to drive 100 yards into a parking lot with minimal braking ability (the emergency brake served as a backup). I left the car parked, and when I returned two hours later to meet the tow-truck, the vehicle started normally with no lights on the dash. Brake functionality had returned, at least temporarily. I thus drove very carefully three miles home without incident. (However, had this occurred on the highway or while in traffic, a fatal accident could have occurred.) I have since found many reports from others who have experienced the same issue, which seems to be common enough to justify a recall, particularly as the brake failure reoccurs (see https://www.carproblemzoo.com/nissan/leaf/2015/service-brakes-problems.php). Tomorrow I bring the car to the dealer to diagnose the problem.

Complete brake failure due to the intelligent brake unit. Driving on the freeway when multiple warning lights flashed at once and I lost brake functionality. I used to emergency brake to slow to a stop. This is an intermittent failure because after it sat for 30 minutes brake functionality returned. I'm very concerned about this issue and have seen multiple people reporting this issue for Nissan Leafs.

The intelligent brake control unit has gone bad. I was driving home and I was preparing to stop at a stop sign . I pressed on the brake pedal and the would not stop. Luckily there were no other cars or else I would have been involved in a car accident. I had the car towed home then I drove it to the Nissan dealership. They ran a diagnostic and they said that they found multiple codes for the brake booster. They recommend that the intelligent brake control unit be replaced. At the time of the incident, the abs light went on, and the traction motor light went on. When I pressed on the brake there was a squealing noise coming from the pedal. That was the first time that ever happened. I reached out to nissanconsumeraffairs.com for assistance to help with the cost of the part. They said that they could not help. My case number is [XXX] and the person that was my contact was [XXX]. Her number is [XXX]. I have read various accounts of where the same part has failed on many Nissan LEAFs. This should be a recall where this part should be fixed for free. It is putting many lives in danger. I hope that you can help me out as well as the many people that drive this car make and model.

I was driving my 2015 Nissan Leaf and attempted to decrease my speed for an upcoming right turn. When I put my foot to the pedal i realized it became stiff and my vehicle was unable to slow or come to a stop. I was able to make the turn safely as I was not at an itial high speed, however, as I approached a red light, i continued to observe the spottiness of my brakes before ultimately pulling over at the nearest gas station about 10 ft further from the right turn where my brakes first failed.

This is to update my report from earlier this month, NHTSA ID Number: 11455211, because I don't see any way to revise it. The dealer repaired the brake failure at a cost to me of $4329, in addition to the $155 I had paid when they could not find the cause of the problem two weeks before. So my total cost is almost $4500 for what certainly appears to be a well-known manufacturing flaw affecting drivers around the world. The dealer told me in no uncertain terms that the car was unsafe to drive, and they knew of no other fix than to replace the entire Intelligent Braking Assembly, so I had no choice. I believe a recall is in order before there is a serious accident, if there hasn't already been one. Consumer stated he did not qualify to be part of that recall. Car has been repaired.

The contact owns a 2015 Nissan Leaf. The contact stated his wife was driving approximately 30 MPH as she was slowing for a traffic signal, the vehicle lost all brake function. The contact's wife safely steered the vehicle to the side of the road. The contact stated that he observed that the brake light, ABS light, and the traction control warning light were illuminated. Additionally, the contact noted that when he stepped on the brake pedal there was only a clicking sound and the pedal was depressed to the floorboard. The contact had the vehicle towed to his residence. The contact had not taken the vehicle to a local dealer to be diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 55,000.

On Feb. 16, in about 25 degrees F, my wife pressed the brake pedal and the car did not react at all. She then jammed the brake pedal to the floor and it seemed that the anti-lock brakes stopped the car. She turned the car off and on again, and drove right back home, only about a mile away. I drove the car carefully that day without incident. We took it to Middletown Nissan as soon as they could get us in, the next day. They could not duplicate the problem and tested various components. Everything passed their tests, so we assumed the problem was isolated. Then, today, March 4, at 29 degrees F, the brakes failed for me on a very busy road. Again, it was at a slow speed, as I was approaching a red light. Again, it took pushing very hard to the floor to get the car to stop. All the warning lights on the dash lit up, and there was an odd buzzing sound coming from under the hood. I drove the 3 miles home very slowly and carefully, and the brakes failed in this same way every time I tried them. I called Nissan customer service and they (Lydia) indicated that they had no information about this problem and suggested I go back to the dealership for further investigation. This is what I will do. I am waiting for a call back from them now, but it's Friday afternoon and I am not hopeful that they will be able to get my car in there today. It's very frightening and unsafe when you don't know if your brakes are going to work. I mention the outdoor temperatures because I've seen some information about 2015 Leafs being recalled for a cold-weather brake failure. It's not been in extreme cold that we have had the issue.
