NHTSA Complaint #11712595 — 2016 FORD ESCAPE

I have a 2016 Ford Escape SE with the Ecoboost engine. I have been experiencing the same issue with misfires in port 4 which also shows an open circuit every time as well for over the past year. The dealership has replaced everything underneath including but not limited to my spark plugs, wires, coils, and even my entire wiring harness. The issue is still happening and they do not know what is causing it. I think my vehicle may fall under the complaint failure FORD currently has on their 1.5, 2.0, and 2.5 Ecoboost engines. It has been to the dealership for the same repairs over 8 different times. When is enough actually enough. I have lost power several times in traffic and it's like slamming on my brakes. This is how bad the misfire is. My check engine light has been flashing due to this issue as well as being on solid. Please help or advise.
