NHTSA Complaint #11610842 — 2013 FORD ESCAPE

My 2013 Ford Escape SEL FWD has been having warning light to "check engine" for a while. Mechanic read a misfire and changed thing. As it continued, Mechanic said computer needed to be "flashed" since it was not an engine problem they found. It went into check engine between 48-55 mph. Later the engine just quit with hot engine warning and antifreeze was empty. Refilled, drove home. The car continually runs our of fluid without obvious signs of leakage. This antifreeze problem continues, occasionally we see smoke from the engine but cannot find a source when we pull over to look. Smells like antifreeze. The car can drive 50-60 miles on a full antifreeze reservoir before getting too hot. I see multiple concerns over this issue but no recall.
