Add gas to the tank the gauge will show empty for a while and then will gradually over one to two days get to the "right" amount in the tank. Tank does not reset show empty when fuel. Eventually reset to correct status the next does. Distance till empty does not reset. I found numerous complaints about this on the internet and the dealer acts like I am the first one to bring this issue to them. This creates a huge safety risk of not knowing what the correct volume is. Many Nissan owners are reporting this issue and nothing is being addressed.
