2022 Nissan Leaf Brakes Problems

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.

It has happened multiple times that if I hit a pothole while braking, the brakes stop working until reapplied.

The contact owned a 2022 Nissan Leaf. The contact stated that while his wife was driving at an undisclosed speed, the brake pedal was depressed but failed to work properly causing her to crash into the vehicle in front. No warning lights were illuminated. The contact stated there was a minor scratch on the front bumper. No injuries were sustained. No police report was filed. The manufacturer was made aware of the failure and sent an engineer to the dealer to diagnose the vehicle. The vehicle was diagnosed, and the contact was advised that braking did occur during the impact via the black box. The contact sold the vehicle back to the dealer. The failure mileage was 24,795.

I was driving on the highway when the car in front of me applied their breaks - I took my foot off of the accelerator but the car did not slow down. I applied the breaks but they did not work - in fact, the car seemed to accelerate. I heard the collision alarm sound but the automatic emergency braking system did not engage or stop the car, so I crashed into the car in front of me. Air bag deployed and then the car filled with smoke from the batteries but I couldn't get out as the power locks didn't work or allow me to open the door. The EMT's had to break the rear window to get me out of the car

On my 2022 Leaf I use the epedal system, which is supposed to operate as a one-pedal driving, meaning when you the car is in epedal mode, you can drive the car with one pedal. When you press the accelerator the car will move forward and when you let go of accelerator the car will come to a stop. However, sometimes the car does NOT come to a stop and it will coast as if the epedal is not engaged. This happens regardless of the batteries SOC (state of charge), weather, angle of the road, temperature, or road condition. When epedal is engaged and you lift off the accelerator, the car should always come to a stop, and it doesn't. This is dangerous because there have been many times where I have ran a stop sign or almost hit the car in front of me because I've had to slam on the brakes at the last seconds. Sometimes the epedal system works great and the car will come to a stop, but many times it does not. The braking should always be consistent and it is not, making this feature dangerous to use because you can easily hit the car/something in front of you. I know how the system works because this is my second Nissan Leaf. In my 2018 Nissan Leaf, the epedal was consistent with the braking; it always braked, no matter the situation. The 2022 does not, and it's dangerous. I brought the car to the Nissan dealer and of course they can't find anything wrong with it. There are several others I've found online that have the same issue: epedal braking is NOT consistent and it should be. There are no warning lamps or messages that come up on the dash. I'm asked to provide a date, but this happens every day. Every day the braking is inconsistent. his has been happening since the first day I bought the car in November of 2021.

I had an accident that totaled the Leaf the day after I bought it. It was dark. The road was more congested than usual and a dog ran out into the road. According to eye witnesses, three vehicles including two Honda SUVs (the first vehicle that stated the whole mess didn't stay) managed to brake to a complete stop without rear ending one another. The Nissan Leaf could not brake quickly enough and I rear ended a CR-V with enough force that the Leaf airbags deployed and I could tell the Leaf was totaled at the scene. The emergency braking system never engaged and the brake pedal felt the same from beginning to end. I was not tailgating. The Leaf felt enough like my 2020 Kia Niro that I made the mistake of not being more cautious with a vehicle that was new to me. Bottom line: I expected the Leaf to behave in an emergency the same as a vehicle I had been driving without incident for 18 months and it didn't. My 2020 Kia Niro does not have emergency braking and I hadn't planned to test it out with the Leaf. Being dark, I saw the instant the vehicle in front of me slammed on their brakes and slammed on mine, but it felt the Leaf wasn't slowing down fast enough. Not nearly as quickly as the Honda.

The E-pedal was on. Trying to park car and it jumped the curb when it lurched forward and brakes would not engage so I had to hit a tree to stop the car.
