It is still under factory warranty so take it to the dealership's service department.

As Bob said, bring it to the dealership under warranty. Unless you can see a visible leak, a new vehicle should not require more coolant in only 10K miles. YOu could have a problem with turbochargers. I believe Ford uses the engine coolant to cool the charger, could be a problem there.

Check your temperature sensor. 1299 code. Mine went bad. Changed it out and problem solved. It’s located on driver side next to your cylinder.
