I own a new 2017 Armada SL by Nissan. Fuel tank is 99 litres. Driving to empty bottoms out at 66 to 70 litre usage only and gauge no longer gives your driving distance to empty..Why fill up a tank when 1/3 of the fuel tank capacity is unused.
Can the gauge be tweaked to better show gas tank empty. My mileage distance then should increase by 1/3 more miles or Kms

try a good reprogrammer, they can often reset values of sensors like fuel sender But really, that problem just shows the poor quality of modern nissans, i would take it back to the dealer and make them fix it right under warranty.
