Hi there,

This sounds like a possible head gasket issue to me. The coolant leaking to an invisible location sometimes means it's leaking into the cylinder and then burning out with combustion. Typically what I would do would be a pressure test on the cooling system to see if I can locate the source of the leak. If it's not visible then its likely the engine is using it. The pressure cap can be tested as well of course. But since the car is losing coolant it seems to indicate a leak or burning it compared to just blowing back from the radiator to the overflow.

I would ask for a pressure test and go from there.
