2015 Nissan Leaf

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 while driving approximately 45 MPH, the engine temperature warning light was illuminated on the instrument panel. The contact depressed the brake pedal and pulled up the parking brake; however, both failed to operate as needed. The contact made a right turn safely and ran onto a curb to bring the vehicle to a stop. The contact drove safely to the destination. The warning lights disappeared. The failure recurred twice within two weeks with no warning light illuminated. The contact notified the manufacturer and was informed that a previous recall had been performed. The vehicle had been towed to the dealer to be diagnosed. The vehicle had not been repaired. The approximate failure mileage was 82,000.

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.

In minus 12 degree temperature, I traveled to a store without incident and parked. Upon returning to the car and starting it, several warning lights went on, including the brake warning light was red, the electric shift control icon was red, VDC indicator light was on, master warning light was red. (may have been other warning lights on). Message was displayed to use parking brake to stop the car.Before applying the parking brake I tried to drive cautiously as I was on a small slope and the display showed my battery level was ok, and ample for the miles to go home, When I tried the brake there was a clicking sound somewhere underneath the car. There was no brake action so I stopped by using the parking brake. I tried this slow roll out two or three times to confirm I could stop the car if I used the parking brake, and there seemed to be no other cautionary problems showing. I was able to drive home with my caution lights, driving on the side of the road, going no more then 15 miles per hour, and using the parking brake when I needed to stop. It was extremely unsafe but most of my ride was uphill going home, and on a Saturday morning at 9am, in sub zero weather, traffic was very calm. The realization of my drive coming into town with most of the trip downhill set in and realized how lucky I was, and how I could have put myself or others in severe danger. I am researching now and will need to find a dealer or independent service center to review the vehicle.

I was at Ralphs parking lot ready to leave last Friday (11/5/2021), as I turned on the car, BRAKE'S light got lit up and when I pressed my foot on Brakes and put it on R (Reverse), I realized the Brakes were not working and the car was going backwards beyond my control. I immediately pressed the button and turned the car off. I left the car at Ralphs parking lot and towed the car to Glendale Nissan (California) next morning. They checked and said the Brakes are running on a very low battery and it needs to be fixed. My car has a very very low mileage and this must be a manufacturing defect. Since there was no recall on my vehicle for this issue, they are charging me $450.0 to replace the battery, plus more for other adjustments, for the total cost of $1,200, As I searched the internet, it seemed that there were recalls for this exact issue for 2015 Nissan Leaf ( I have the same). How come my vehicle never received any recall notice for the same issue. I was lucky that this happened in a parking lot. If this had happened while I was driving or picking up my grandchildren, it would end with a devastating results. Please contact Glendale Nissan and let them know not to charge the customer for a manufacturing defect.
