Cooling fans running when they shouldn’t

It can be hard to tell because it's obviously not a big leak since you haven't noticed it until recently and probably only does it when it's hot. Is it better now after topping it off? If so, just monitor it and see if continues to drop. Like I mentioned before, the only common leaks I've heard are from the overflow tank fitting or at the water pump itself. Previous Ecoboosts also leaked at the turbos, but I haven't seen that much in the Gen2

 

So, I have experienced this exact same problem with my 2017. Loud as engine fan all the time even in cool conditions. Truck is under warranty and the dealer refused to recognize the issue. I've since switched dealerships, fyi. Ultimately I purchased a 170 F thermostat and replaced the stock thermostat and the fans have not come on since. DONE. I bought the SPD thermostat.
