Anyone else know about the known issue with coolant leakage into the 4th cylinder? I have a Ford Fusion 2017 with 100,800 miles. Immaculately cared for until engine light turned on a few months ago. Took it to 2 Ford dealerships and they all said the same thing. Sent a letter to Ford Motor Company in Dearborn and they said they can't do anything unless a recall is called for, in which case to save my receipts.
