I currently have a 2016 Ford Fusion SE with the 1.5L engine. Upon starting the car, the check engine light came on and idled roughly. After scanning the codes for the check engine light, it was determined that it was experiencing a cylinder 3 misfire. I took the car to the dealership and upon repair, they uncovered there was a coolant intrusion coming from the engine and either a "band-aid fix" was needed for $3,500 dollars or a full engine replacement for $8000+ dollars was needed. The dealership confirmed that they have seen this being a known issue for this type of vehicle/engine but there was no relief for the repair. After moving forward with the $3,500 repair to replace the head gasket, it was determined that even then the car was inoperable, and I was left without a vehicle and a bill to pay.
