2020 Nissan Leaf

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.

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.
