mine inaccurate also at times
If I fill up, and top it off more, the gauge registers full and then at some point id say sometime within a half hour i'll look down and it'll be on empty. The mfd will not show a range either. I have to pull over, turn off the car and start it again and its fine. This only happens when i topped off on a long drive (you know, its not good enough that I can get 650 miles on a tank, I need to squeeze a few more!)
