2015 FORD FUSION with 103000. miles

Just got this Ford vehicle a couple months ago and for some reason my car wouldn't start. I ran a diagnostic and had numerous codes P0300, P0301, P0302, P0303, P0304, P0030, C0014, P0047, P0141, and a few others. I looked for loose wires, checked fuses, plugs etc. The only thing at this point i noticed was two cracked spark plugs, so i replaced all off them. After that the car started so i thought it was fixed. Closed the hood turned the car to off, then tried to start it again. It did not start. So i checked all the fluids and seen the antifreeze disappeared, i had previously filled it. I looked for any visible leaks, puddles, and checked for wet carpet and found nothing. I went and bought another large jug of antifreeze put it in and watched it all disappear before my eyes. I could not figure it out, but i got the car started and still continued to get massive error codes, white smoke, rough sound, etc. Then searched more and found it sounds like blown head gasket, i checked and the oil had a milky tint. This i then found was a recall for my vehicle, so i spoke with someone from Ford on march 20, 2021 and they said they needed to check if my local Ford dealership had the parts to get my car in or if they needed to order the parts. I was suppose to get a call back but have not heard anything. I have not been driving, i did use leak fix it seemed to stop the leak and clear the codes but my dash check engine light keeps flashing so i didn't want to cause further damage. The recall number i found was nhtsa id number: 10174400, my car is a 2015 Ford Fusion ecoboost 1.5l, vin number# [xxx], and my local Ford is in heath, ohio 43056 at mathews Ford. I am getting the impression this is going to be at my cost after contacting Ford again, now telling me that it will need diagnosed at Ford, and may be at my cost. Why doesn't the recall list under my vin? Information redacted pursuant to the freedom of information act (foia), 5 u.S.C. 552(b)(6).
