Adaptive Cruise Control problems of the 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.

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.
