NHTSA Complaint #11585809 — 2018 FORD ESCAPE

I took my wife car to Ford in Yuba City for a engine light for P1450 Unable to bleed up fuel tank vacuum. I had the dealership pick up my car and take to the dealership to replace the purge valve. The quoted me 1 hr and changed me two. On the paperwork they said there was an engine misfire which nobody said anything to me and I didn't ever had that error on this car. They drove my car to my house like this. I looked at paperwork and was surprised so I checked the car out and got a code po302 for cylinder 2 misfire. I popped the hood and saw that the cable was put in there lazy and there was a gap i the air tube to the air filter. I talked to the dealership and brought it in and they told me I have coolant in my motor and will need a short block replacement. I had no issue before the purge valve and with the on going issues with the coolant in motor issues with this type of engine. I feel ford should take car of it. I bought this car with 36 miles on it and it currently is at 96k or so. I know there was a free replacement for 7 year or 84 years of warranty. Is there anything Fork can do since I really don't want to go the legal route but will if I have to
