Got the notice in an email about a week before I got the letter in the mail (email was not from Nissan but a 3rd party). Basically on the 2018 and 2019's, if you change the settings with the camera on, it remembers those settings, so if you shut the camera off while in reverse, the next time you go to reverse the camera will stay off. The recall is to do a software update to where every time you go into reverse it will default to camera on.
