2018 Nissan Leaf

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.

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)

The incident occurred at a stop sign where I was waiting behind one other vehicle. The vehicle ahead of me accelerated from the stop sign to turn into traffic, but abruptly slammed on their brakes. I had began accelerating up to the stop sign and was unable to stop before impacting the car in front of me. As soon as I saw the vehicle was braking, I immediately slammed on the brake pedal. Braking did not immediately occur. My wife said she was afraid that I had slammed the gas pedal because she could hear my foot hit the brake pedal and neither of us felt any braking. The Nissan Leaf was in Eco Mode and ePedal at the time of the incident. I believe that the transition from regenerative braking to mechanical braking delayed the stopping of my vehicle. We were lucky that this happened in a very low consequence situation, but if this happened with a pedestrian or at a higher speed where emergency braking is required, this delay in braking could be dire. In addition, this vehicle is equipped with automatic emergency braking. I have heard this feature go off before in this specific car when a car is braking faster than I am. In this case, the alarm and assisted braking did not go off, despite a car stopping within extremely close proximity.

Twice now - both times on the South Bound Richmond Bridge, the Automatic Emergency Braking lights came on and slammed on my brakes for me, as if I was about to crash when I was going 65 mils per hour, no one in front or behind me and no traffic, accident or reason. I almost lost control of the vehicle and would have caused an accident had anyone been closer to me.

I was pulling slowly into a parking spot. The vehicle accelerated all of a sudden on its own very fast. I slammed on the brakes and the vehicle did not stop. It ran us on a sidewalk and crashed into a pole. Luckily no one hurt. Progressive is calling the car a total loss, but they have done nothing The car is still at a parking lot near the crash. Nissan is also doing nothing. I feel that I deserve better treatment. I have a good driving record and my rates are going to go up. I have not been offered a replacement car. The car is very dangerous and I would never drive another Nissan

On may 12, I was in a long line of cars at a red light , stopped. all of a sudden my car started moving and accelerating toward the car in front of me. When I got over the initial shock, I started stamping on the brake (2-3x) and nothing happened. I clipped the other car as I yanked the car out of line into the turn lane. I turned off the car and shook. Then I handled the insurance stuff with the other guy. I did NOT take my foot off the brake. (I reported this incident to the NTSB, BTW.) I wanted the collision center and Nissan to look at the black box, but the garage didn't and Nissan said that was no black box.

I was stopped at a light, in a long line of cars, my foot on the brake, a few feet away from the car in front of me, and the same in back. All of a sudden, the car started moving, accelerating, jerking forward. I was shocked, pushed down on the brake, nothing happened. starting pulling the car out of line because I was going to hit the car in front of me. I was pumping the brake, and NOTHING HAPPENED. Clipped the car in front's rear left bumper, wrecked my front right bumper. Finally pulled into the turn lane and finally the brakes caught. It was like someone had taken a gizmo and turned on my car (like the OnStar mess a few years ago.). Nothing like this has ever happened to me, in any car, including this one, until 5/12 at 2:00 pm. It was terrifying.

Around 45 degree weather, while driving on the freeway, a warning light indicating the AEB had been turned off started flashing on my dashboard without any collision, jerky movements, sudden stops, or changes to settings. At the same time this happened, my electric battery mileage started to fluctuate erratically (73% to 8% to 14% back to 70% and finally to 60%). This is extremely concerning because of the car immediately brakes or if the battery dies on the freeway, it could cause a major collision.
