It is a design issue. The issue is that the fuel sensors malfunction/loosen and tip up. That results in the sensor’s bottom being higher than the tank’s bottom: showing “empty” when it isn’t. It also shows a faulty “xxx until empty” reading for the same reason. So... owners have 4-5 gallons left in tank, but the car thinks it’s empty. You could still drive 150-250 miles, theoretically. The problem is that they break off on random cars at random times, to various degrees, so it threw Toyota off. There is a fix out though. Takes 3 hours at the dealership.
