Automatic Emergency Braking problems of the 2020 Nissan Leaf

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.

A yellow warning ?? and two cars crashing comes on and during driving the car applies sudden breaking. I took the car in for repairs but no time line was given for repairs or parts. Also even though it's under warranty the dealer and the headquarter would not give me a rental car until the repairs are made.

What component or system failed or malfunctioned, and is it available for inspection upon request? aeb may have malfunctioned. Yes, I will provide the car for official inspection. How was your safety or the safety of others put at risk? possible injuries from abrupt braking; possible and likely rear-end collision if drivers behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? no. I have not contacted Nissan. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no. I have not contacted any gov agency or insurance carrier. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? yes. I saw three red flashes and associated sounds warning of imminent collision - even though nothing was in front of the car that would cause the aeb to engage. Below is my incident description: my work has an underground garage. I was entering the garage, went down one level, and then on my way back up the next level. There are speed bumps going down and going up, so you cannot go very fast. On my way back up (incline), the aeb unexpectedly activated with red buttons flashing about three times with sound (as if I was about to crash into something) and then the car abruptly stopped. I stepped on the accelerator to try and go and it would not budge. I'm still on the incline. If there were cars behind me, I would have most likely been rear-ended because this incident came out of nowhere and my car just stopped. There were no moving cars in front of me that would indicate a near collision, only parked cars. I had driven this route in the past so I don't know what was different today. Car just stopped. I am still on incline; placed car in park; waited few seconds; placed car in drive and was finally able to move the car.

"automatic braking system failed to engage" on a offramp lane from freeway 5 southbound to crown valley parkway off ramp while traveling approximately 25mph I rear ended a vehicle that was at dead stop and that vehicle rear ended a second vehicle. California highway patrol was called and report was documented which is attached. This happened on December 22,2020 at about 7pm, dark clear evening in the city of mission viejo. It was on the straight freeway lane leading to the offramp with other lanes on the freeway moving freely. Upon discussion with Nissan investigation (claim no. 42994813) 615 725 7590, they summarized 10 page disclaimer from owners manual stating that braking system is not 100%. Its understandable if the vehicle was old but this is a new vehicle with what is advertised as a automatic braking system and that system did not work. I manually braked to a crash.
