2020 Nissan Leaf

While driving with cruise control set to a certain speed (i do not recall the exact speed it was set to) I pressed the button that lowers the current speed it is set to, but instead of lowring by one mph it raised the speed, pressing again raised the speed again. this continued a few times until i turned off cruise control. The system has been buggy in the past, for example not responding to a button or raising by 2 or 3 mph instead of one (the Leaf goes one by one, not jumps like some vehicles). But this was the first time i saw it actually raise speed in response to a button that should lower it and that seems dangerous. The problem has not been reproduced or confirmed by a dealer or service center. It has not been inspected by anyone since the incident occurred. There were no warning lamps or messages. The overall bugginess has been noticeable for a long time (perhaps always?) but this occurred (raising the speed instead of lowering it) for the first time yesterday.

the front collision detection system frequently stops working, especially when there is wet weather. The little light on the dash comes on that shows it's not working. ALSO. My car has a serious battery issue that is not related to the fast-charging issue with the current recall. The battery frequently loses charge while driving, and I have to cut trips short and head home in "turtle mode".

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.

About 3 months ago, I took this car in after receiving a recall notice for unexpected acceleration while on adaptive cruise control even though this was an issue I had never experienced before. But on monday, driving in stop and go traffic in light rain (intermittent wipers on slow setting), all of a sudden the car started accelerating directly towards the car 20 feet or so in front of us; the brakes had to be manually slammed on to bring the car to stop with now only 2-3 feet or so between the two cars. This was very alarming. When I spoke to the dealership about them needing to fix this safety issue and how I thought it must be related to the recall, they said it could not be given it first happened 3 months later and I would have to pay for an evaluation and if they found anything wrong for the repair. I am reporting this and would like to know if other Nissan Leafs are seeing the same issue post-recall repair. I will say it doesn't happen all the time since I like and use adaptive cruise control regularly. I carefully tried it after this event but with much more distance between me and the car in front and it did slow the car down as it normally does when traffic slowed, but again, I never got as close to the car as this time and it was not raining so who knows. I have reported this to Nissan corporate and was told someone would call me back in the next few days.

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.
