The vehicle was taken to a dealer where it was diagnosed that the brake module booster needed to be replaced. The vehicle was not repaired. The contact researched and was made aware of NHTSA Campaign Number: 16V119000 (Service Brakes); however, the VIN was not included in the recall. The manufacturer was notified of the failure. The failure mileage was unknown.
NHTSA complaint #11756786 — an unverified report by a vehicle owner.
The car was parked in a parking lot, and when we turned it on and pulled out of the space, the brake light, ABS light, and other warning lights came on and the brakes went soft. We pulled back into the space and tried again, thinking it was a fluke and heard a strange noise coming from the car when it started. Again the lights came on and the brakes did not work. We had it towed to our normal mechanic and then to the dealership when the mechanic was unable to figure out what was wrong. The brakes looked to be in good repair. The Nissan dealership was unable to reproduce the problem and found only old codes in the system. The codes listed on the receipt were FFD high key cycle counts, C118A, U1000 (ABS, EV/HEV), P3195, B29C1 However, after I saw similar complaints related to the battery in this car and told them about it, they found that the 12V battery was leaking. They replaced the battery and flushed the brake line to be safe, but did not charge us the diagnostic fee since they were unsure if they fully fixed the issue. I had recently felt like the brakes took more pressure than normal (all the way to the floor) to stop on the highway once recently and so did my husband but we both thought we were imagining things. 2 years ago we had a similar issue happen but the mechanic just sent us back home after not being able to find anything. The codes on the receipt from 2024 are not very legible but I think they say "41000Gn Comm Circuit" "C118A EAS System" and "41100 Electronic Back Return."

THIS HAS HAPPENED TO ME intermittently AT FIRST ... NOW permanently AND CANNOT BE DIAGNOSED BY NISSAN. IHAD TOTAL BRAKE FAILURE WHILE ON THE FWY AT 60MPH, THE DASH LIGHTS FOR ALL BRAKE COMPONENETS CAME UP WITH TIRE AS WELL...ALMOST ALL WARNINGS LIT UP AND THE BRAKE PEDAL WENT TO THE FLOOR AND I HAD TO PRESS THE BRAKES VERY HARD AND CAR WOULD NOT STOP BUT EVENTUALLY DID ON SIDE OF ROAD. VERY BAD LOUD GRINDING MALFUNCTIONING SOUND. WHEN I WAS GETTING IT TOWED I TRIED TO TURN ON JUST TO CONFIRM STILL BROKEN STATUS, HOWEVER CAR RAN PERFECTLY TILL THE NEXT INCIDENT WITH SAME DIAGNOSIS. NISSAN 777 HAS GIVEN ME 4 DIFFERENT DIAGNOSTIC PROBLEMS WITH ESTIMATES AT $5,900 MASTER CYLANDER, $3,800 BRAKE ASSEMBLE AND A VERBAL ONE SAYING IT IS THE ACTUATOR. THEIR PARTS DEPT IS incompetent AS NISSAN HAS BEEN ABOUT THIS ISSUE FOR 6 MONTHS NOW. THIS IS BY FAR A TRAFFIC SAFETY ISSUE AND NISSAN IS FAILING TO RECOGNIZE THE PROBLEMS WITH THIS NISSAN LEAF. REDDIT HAS SEVERAL PEOPLE CLAIMING SAME ISSUE AND NISSAN IS IGNORING IT.

I was at a red light on a slight decline with my foot on the regular brake. I am 99% certain the Epedal was on. Something startled me and I took my foot off the regular brake, but the Epedal should have held the car still. It didn't, and I rolled into a Jeep SUV, smashing in the front of my car where the charging port is. Progressive Insurance says my car is totalled. The airbags did not deploy, and no one was hurt, but my passenger, an 89-year old with a recent hip replacement, could have been compromised. I am researching Black Box retrieval options, but they appear to cost more than my deductible. There were no warnings that the system was faulty.
NHTSA complaint #11745363 — an unverified report by a vehicle owner.
This is the third time my brakes have failed while driving, which seems to have something to do with the 12-volt battery. At least at first, I disconnected my 12-volt battery and reconnected it; this fixed the issue, at least for a while. The other day, I was driving down a road near my house and the brakes failed right before I came around a bend. I had to quickly press the e-brake to slow down, or I would have run right off the road. This is definitely a dangerous issue. Please issue a recall for this because I've noticed many other people complaining about the same issue—the same sound, feeling, and symptoms. It appears the brakes are malfunctioning due to a communication error, or a low voltage issue to the brake computer systems?
NHTSA complaint #11733315 — an unverified report by a vehicle owner.
I was driving on city streets at 25 mph or less, using the Nissan Leaf e-pedal system (which automatically slows the car to a stop when you let off the accellerator), when an alert flashed up on my dashboard, saying something like: “e-pedal system disconnected, use brake pedal to stop”. There was also a check engine light and an ABS warning indicator on. When I pushed down on the brake pedal I felt no resistance and no braking action. When I put the brake pedal to the floor, there was a vibration and a little bit of braking, but somewhat ineffective. I drove slow speed to a safe place to stop, and turned the car off. After calling for a tow, I turned the car back on and the brake system functioned normally. I had the car towed to a Nissan Dealership service department. The dealership read code C118A-97 stored as a “past code”. They erased the codes and performed DTC confirmation procedure and code did not return. Dealership service department road tested vehicle and no signs of malfunction. They inspected brake fluid level, level was normal but was dirty. I authorized service department flush and replace the brake fluid, which they did. They again road tested the vehicle, and I picked up the vehicle later.

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.
NHTSA complaint #11712902 — an unverified report by a vehicle owner.
This vehicle is equipped with a feature known as "e-pedal" also known as one-pedal driving which is quite common on EVs. When this mode is activated, the accelerator pedal acts as a speed command (vs. power) and when the pedal is not depressed, the vehicle applies brakes until it comes to a standstill. Recently, the system has demonstrated a fault condition, where the Vehicle Control Module (VCM) issues a fault warning and disengages the e-pedal mode. This appears to occur randomly after the vehicle has been at a standstill for over one minute (e.g. waiting at a traffic signal) where the driver is using the one-pedal system vs. continuously applying pressure to the brake pedal. The safety issue is that when the system detects a fault and disengages e-pedal, the vehicle starts to move forward, requiring the driver to take immediate action to stop unwanted motion. This can lead to a collision with a vehicle or pedestrian in front of the vehicle. The desired behavior is that when the VCM detects a fault with the e-pedal system, it should engage the Park mode and prevent the vehicle from moving forward. The driver must then depress the brake pedal and affirmatively command the Drive mode before moving. Just disengaging the e-pedal (brake) without prior warning of a fault is a safety hazard.

NHTSA complaint #11704452 — an unverified report by a vehicle owner.
While driving normally, yellow brake warning lights came on but I arrived home without incident. Next time I drove, the warning lights were all off, but suddenly the brakes failed almost completely. I pushed the pedal to the floor and heard a grinding/clicking sound, and barely any stopping power. I was only going 25 mph, and was able to stop after 5 seconds of high foot pressure. At the same time, red brake warning light came on. I was able to get the car home very slowly, and strangely I had adequate braking power for the remainder of the short trip (although red and yellow brake warning lights remain on). I am happy to provide the car for inspection. This was extremely dangerous to the nearby pedestrians because I could not have stopped the vehicle had one been crossing in front of me. Had this happened at highway speeds, my passenger and I would have been in great danger, as would have other vehicles.

The high-voltage battery on my 2022 Nissan Leaf is subject to Recall 25V655. The recall notice states that the battery cells can develop excessive lithium deposits, which increases electrical resistance and can cause rapid battery heating during Level 3 fast charging. Nissan instructs owners not to use Level 3 charging at all until a “remedy” is available. The issue is that the remedy described by Nissan is not an actual repair of the battery defect. Nissan states it will install software that monitors for “state-of-charge fluctuation” and, if detected, will prevent the vehicle from restarting or recharging in order to avoid a thermal incident. This means the defect inside the battery cells is still present, and the car may disable itself if the defect begins to appear. The recall materials also state there is no warning before overheating occurs. This creates multiple safety concerns: • The underlying battery defect remains uncorrected. • The vehicle can become immobilized (unable to restart or recharge) if the software detects the condition. • Loss of Level 3 charging capability affects the ability to travel safely or plan charging when needed. • A battery fire risk exists during Level 3 charging if the defect is not detected in time. Nissan’s documents state that the software is meant only to prevent the “progression” of a thermal incident, not to repair the defective battery. I am concerned that my vehicle contains a known hazardous defect that has not been physically repaired and that the software-only response is inadequate to ensure safety. I am filing this complaint so NHTSA is aware that the remedy being offered does not address the internal battery defect itself and may leave owners exposed to continued safety and reliability risks.
NHTSA complaint #11702082 — an unverified report by a vehicle owner.
My Intelligent Brake Unit failed. I was slowing down at a major intersection to stop. The ABS system activated and the brakes did not respond appropriately. The pedal went soft. Multiple lights on the dashboard lit up. My two year old child was in the vehicle with me, and we are still recovering from this traumatic experience. I considered the car disabled and had it towed to a mechanic. I then brought it to a Nissan dealership who identified that the entire intelligent brake unit needs replacing for $5,500, which is more than half of what I paid for the vehicle.

On Monday, I was departing from the supermarket parking lot. As I was waiting at the stop sign to exit the parking lot, my 2020 Nissan Leaf SV vehicle shuttered and there was a blinking notification on the dashboard stating: TM System Malfunction EPedal Failure Suddenly my ability to stop the vehicle was compromised. I turned onto the surface street and continued to pump the brakes with no response. I turned back into the supermarket parking lot and continued to pump the brakes but there was no engagement. I slowly drove around the parking lot trying to stop with no success. I eventually had to turn on the emergency brake and then force the vehicle into park. It was a very scary scenario. I called the dealership to explain the situation and the service advisor suggested that I have the vehicle towed to the dealership for a diagnostic evaluation. After sitting in the car for 30 minutes with it turned off, I turned it back on and drove the vehicle on surface streets to the dealership with no breaking incident. The next day, the service department performed a diagnostic inspection and determined that the 12 volt battery was the cause and needed to be replaced. I was relieved that this was the issue. The technician kept the vehicle one more day to drive it and be sure it was operational. In the end, I purchased a new battery. I am writing your organization to report this incident to try to avoid any injuries or deaths in the future. This incident happened to me without any warning and could have been very dangerous if I was at a busy intersection or on the freeway. There was no warning on the dashboard about the battery or maintenance warning to see the dealer. This needs to researched with Nissan Motor Company.

NHTSA complaint #11666440 — an unverified report by a vehicle owner.
I was driving about 30mph and suddenly out of nowhere my brakes went out. They went out for about 1 second and some lights went out - then I slammed on the brakes, skidded to a halt and stopped in the. middle of the road, nearly crashing. We took it to the garage and they ran two codes and told us to take it to the dealer. The dealer quoted us about $8,000 and said it needed to "replace electrically driven brake control unit AND e-harness (engine room harness) (240123nh1d)". This makes the car dangerous to drive due to failures beyond our control or regular maintenance. This is a car failure and should be covered by a recall. It is simply not safe to drive. Looking online, this has happened to other Nissan Leafs of the same year/model as well.

Hello. I have a 20/20 Nissan Leaf SV Plus. This morning I had a total brake failure for lack of a better term. The E-Pedal system, which I always use, suddenly failed while I was driving, showing a warning on screen that said E-Pedal system malfunction... Please use pedal to break. When I went to use the pedal to break nothing happened except for this horrible sound and feel in the pedal. It barely just finally grabbed a little bit enough to stop before I hit the car ahead of me. But it was nothing short of a total brake failure, both E-Pedal and manual pedal. Extremely distressing. What I want to know is how on earth when the E-Pedal fails, the normal manual brake pedal doesn't work either. One thing to note, I let it sit almost all day while I was at work, went out and tried it, and it suddenly was working. I drove around the parking lot, turned it off...back on ..and then The E-Pedal warning came up again. I then went and purchased a 12 volt battery, as I read in some forums that it's possibly due to that. That also did nothing. Got the same E-pedal malfunction. The main reason I'm letting your agency know, is because I would consider this a total break failure, and completely unacceptable. By sheer luck I was only going about 5 mph when it first happened, and I could still barely break in time. Any help on the Federal level...would be great. Thank you so much for your time.

I was driving my vehicle and the brakes suddenly stopped working. Upon failure, the ABS warning light as well as the braking system warning lights came on. I had to use my emergency brake to stop the vehicle. I had my vehicle towed to Nissan. The Nissan dealership mechanic said it was a Master Cylinder Brake Controller malfunction. It is currently at the dealership and available for inspection. The cost to repair the brake system exceeds the value of the car. This put my safety at risk because I could not safely stop my vehicle. I was minutes away from merging onto the freeway. Had I been traveling at high speeds without any braking system, my life and others would have been at risk.
NHTSA complaint #11635776 — an unverified report by a vehicle owner.
On 3 occasions the brakes have randomly failed when traveling. In 2 cases, stopping ability was non-existent except for the use of the parking brake. In the other case, stopping was significantly decreased. 13-Jan-2025, when traveling straight on a 40mph road towards a busy intersection, when the brakes were applied to slow to the intersection they failed and a red indicator light came on. Stopping ability was significantly reduced, but not completely gone. The car was able to safely divert into a parking lot without incident. When the car was powered off then on, the error went away and the brakes functioned. There were 2 other incidents prior to this, traveling at low speeds in residential areas. Braking was completely gone and I had to use the parking brake pedal to stop the vehicle. Again, after powering the car off then on, the braking system functioned normally.

Car was descending towards Kailua on the [XXX] on Oahu, HI. Dash lit up with warnings and acceleration and brake pedals stopped working. Brake pedal went to the floor with erratic pulsing sensation and very little brake power. Driver drove car into jersey wall to slow and stop vehicle. Battery state was 60% and battery was replaced under warranty about 1 year ago. While waiting for tow, powered on vehicle and symptoms remained as far as I could check. Brakes had no power and had to use ebrake to keep vehicle from rolling. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
