Coolant is leaking into the engine (1.5 liter Ecoboost) in my 2015 Ford Escape (less than 50,000 miles). After the check engine light came on recently (within the last week) the code was read by a local auto repair shop and a Ford dealer. Both confirmed (codes P0302, P0316). I initially went to my local mechanic before going to Ford dealership. He found the coolant was low and the engine was running rough. He topped off the coolant. He mentioned that there was a known problem with some Fords with coolant leaking into the cylinders. I then went to a Ford dealership for service when the light came on a second time becuase I have an extended warranty. The Ford service tech said I need a new engine becuase coolant is leaking into the cylinder. I’m reading about this now when I researched it. I never received a Customer Satisfaction Program 21N12 letter from the Ford dealership I purchased this from in 2021. My Ford was manufactured in Louisville which seems to be common in Fords with this problem. Someone from the warranty company will inspect the car to confirm within 24 to 48 hours.
