NHTSA Complaint #11478114 — 2016 FORD FUSION

I started getting a check engine light on the car, hooked up obd miss fire cylinder 3, changed ALL the plugs and coil pack for cylinder 3. Cleared codes, ran fine for about 5 days. Misfire on cylinder 3 again, swapped cylinder 2and 3 coil packs, still misfire on cylinder 3 pulled plug, brand new mind you, looked horrible, cleaned it and swapped it with cylinder 2 plug, still misfire cylinder 3, car seemed to run fine when at higher rpm, but at idle was rough. Wife went to leave later in car….. engine coolant over temp came on, I get to the house, and notice that the coolant tank was low, added some coolant, started it back up, coolant seemed to disappear. Checked the dipstick… oil was a milky color so it’s either bad head or bad gasket. Upon looking this problem up there seems to be A LOT of problems with this design on fords motors where coolant is getting into one of the cylinders and ruining the engine.
