The fuel gauge is also not linear. There is more fuel in the top quarter of the gauge and it proportionally reduces with each quarter which is why when you are past the half way mark, the amber warning comes on quickly and the red even more alarmingly quickly! The NAFTA fuel gauge software update is to do with something about refuelling under specific conditions.
On my 2.0 it says around 50 miles usually when amber light comes on (2 bars) and depending on how you are driving updates the "estimate". If you are driving a lot of urban or start-stop the estimate usually turns to --. But when I am cruising at steady speed which means steady fuel consumption, the computer decides this is enough and gives a better estimate. Most occasions when it turns red, the estimate disappears but not always (cruising). The best estimate I have had when red is around 35 miles when doing an average of 40mph in my usual commute. The 2.0 engine needs time to settle and the consumption usually improves once you have a few thousand miles in the bank.
As posted by MacGeek on the US forum:
"Published today, for incorrect fuel level readings in specific conditions.
The specific conditions include being parked on a grade of more than 10 degrees, staying in that position for a long enough period of time (approx. 30 minutes), and having a tank filled between 50-75%. At this point, the vehicle will think it went through a refuel and add a notch or two to the fuel gauge upon restart. This additional fuel reading will persist until an actual refuel takes place; after which, the fuel reading will be accurate once again.
Fix is a software update."
