NHTSA Complaint #11546699 — 2017 FORD FUSION

I purchased a used 2017 Ford Fusion SE Ecoboost with 77790 miles on August 4, 2023. 2 days after purchase, the check engine light illuminated. I brought it into a local mechanic to run a diagnostic test. The diagnostic showed “misfire-cylinder 1”. The mechanic recommended replacing all spark plugs and the cylinder 1 coil pack. Repair was done and seemed to have been running well. 2 days later, the check engine light came back on. Brought it back into the same mechanic. The diagnostic showed “misfire in cylinder 2”. The mechanic recommended replacing the remaining coil packs but thought that the problem could possibly be a blown head gasket. I decided to replace the remaining coil packs in hopes that this would remedy the issue. 2 days after bringing the car home, check engine light came back on. I brought the car to a different mechanic for a second opinion. This mechanic diagnosed that “misfire in cylinder 2” was happening again. They mentioned that this ecoboost model is known for issues with carbon buildup. They used an intake cleaner to clean out the carbon and saw noticeable improvement. Later that afternoon, I came to pick up the car, and noticed that the cold start was much rougher than before. Once again, when driving home from the mechanic, the check engine light came on. Next day, took a short drive and a warning stating that the engine was overheating and coolant was low appeared. I filled the coolant and brought car to another mechanic. That’s when I was told that the engine needs replaced due to coolant leaking into cylinders. Still waiting to hear back from Ford to see if they will help with cost of repairs. Quoted $6300 to fix. This is my primary source of transportation and now I’m without a vehicle. This is also a hardship due to the fact that this vehicle was just purchased with no additional funds to pay for repairs. Please help!
