Yes, finally, I thought I was the only one taking crazy pills! I have experimented with waiting till my fuel tank hit empty as well and blinking yellow and the most I ever got was 13 gallons. Now, if you look at the Quick Reference Guide that came with your 2013 Ford Fusion, or you can check it out on the Ford Owner website, it says "Your vehicle has a fuel tank capacity of 13.5 gallons (51.1 liters)." When I saw that, I was like, uh.. that has to be a typo so I googled and everybody and and their mother says it is 16.5. Now, if the fuel tank capacity really is 13.5, then that would explain A LOT, 13 gallons, with .5 gallon as reserve makes more sense, than say 13 gallons with 3.5 gallons in reserve. However, if there is a 3.5 gallon reserve I would MUCH rather know that, and have the comfort level of knowing that, rather than guessing that my fuel tank is not doing what it is suppose to do. But if that's not the case, that is straight up false marketing. I don't know what to do yet, I've taken my car in for the recalls and now this potential problem. And since it's not just me and it seems like a lot of people, this might be an actual and not potential problem. I hope somebody can get some answers to this so we can all decide where to take it in to be looked at... but this is the first new car I ever bought and I always feel like I'm waiting for the next shoe to drop from Ford.
I absolutely love my car but I'm now thinking I should have just stuck to Boringville and bought the 2013 Honda Accord.
