NHTSA Complaint #11636177 — 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.
