2018 Ford Escape

Component or System: Engine – Coolant intrusion into the combustion chamber (cylinder 2). The vehicle and documentation (dealer diagnostic report, photos) are available for inspection upon request. Safety Risk: Coolant intrusion causes engine misfires, loss of power, and rapid coolant loss, which can lead to sudden engine stalling or hydrolock at highway speeds. A stall could result in loss of power steering and braking assist, creating a serious crash risk for occupants and others on the road. Confirmation: The problem has been reproduced and confirmed by a Ford dealership using a borescope inspection. Inspection: A Ford dealership service department has inspected the vehicle. They confirmed coolant pooling in cylinder 2. Warning Signs: The check engine light first appeared in early July 2025 with a misfire on cylinder 2. Spark plugs and other components were replaced, but the issue returned within two weeks. The engine misfired, produced white exhaust smoke, and lost coolant over time.

My check engine light came on Saturday August 23rd. I took my car to my local Ford dealership on Monday August 25th and on Wednesday, August 27th the Ford technician verified a misfire and found coolant was low. They removed the spark plug and found cooling system was under pressure. They found coolant entering into the cylinder via the cylinder head and that my vehicle now needs a new engine. This problem has been confirmed by the dealership and my only option is to purchase a brand new engine for my 2018 Ford escape that has less than 40,000 miles on it. An engine failure at just 40,000 miles is simply unacceptable and raise serious concerns about the reliability of this model. I am aware that engine issues on certain Ford escapes have been the subject of multiple customer complaints and I strongly believe that this may be part of a broader quality or manufacturing issue. There are numerous reported cases from 2018 Escape owners describing engine failures, tied to coolant intrusion and instances where an engine fails unexpectedly often linked to coolant, entering the cylinder and requiring full engine replacement, which seems to be a common pattern in these 1.5 L and occasionally the 2.0 eco-boost. While no formal recall exists for this Ford has implemented a customer satisfaction program 21N12 which addressed coolant intrusion into the engine, especially affecting 1.5 L eco-boost engines.

Had a lot of knocking in the engine on startup and sometimes driving down the road. Engine check light went on, used code reader to diagnose and it said misfire on cylinder 2. Replaced spark plugs and ignition coils to solve problem. Ran well for about a week, week and half before had the same issues pop up again. Then all of the sudden I’m driving down the road and the temp spikes in the engine and warning light comes on about car overheating and to pull off the road . I was on the highway so I let off the gas and the temp came right back down. Took the car to a Tire Kingdom to get it checked out and the coolant is almost all gone, it’s leaked back into the engine and the head gasket needs replaced. Call Ford to see if they would cover service and the dealer and Ford corporate both said it would not be covered, despite TSBs being out about this issue.

Due to a known manufacturing defect in the casting of the engine block, coolant leaked into the #2 cylinder causing failure of the engine. Due to the fact that this is a known issue by Ford, they will do nothing as the vehicle is no longer under warranty. The extended warranty we purchased will not cover the damage or repair as it is a "known issue from Ford." Vehicle is available upon request, if catastrophic failure of the engine had occurred possible loss of power and or control of the vehicle, vehicle was inspected at a certified Ford dealership, check engine and a lot of white smoke the day of service appointment, rough idle the day prior

MY FORD ESCAPE IS A 2018 WITH 54,000 MI AND COOLANT WAS LEAKING IN THE CYLYDERS. IT WAS SOLD TO ME AS A LOW MILAGE MINT COND. SUV THROUGH CARMAX WHO DID NOT DISCLOSE THIS PROBLEM AND ALSO FORD. NOW ITS SITTING AT THE FORD DEALERSHIP FOR 2 WKS WITH NOTHING DONE AND "WAITING TO HEAR" FROM FORD. THEY SAY THE JOB COULD BE UP TO $11,000.

A cracked engine block caused coolant intrusion into my Eco Boost engine resulting in overheating engine. I was almost stranded in the Cascade mountains. Randy Wright at Bill Pierre Ford of Seattle says he sees a Ford Escape with this problem once a week. After multiple conversations with Ford corporate, it appears Ford is aware of the problem but unwilling to issue a recall for these dangerously defective engines. The vehicle gave no prior warnings before the overheating took place.

In 2021 my engine was replaced by the dealership I purchased it from, with a manufacturer made engine. The issue was that the coolant was leaking into the cylinders causing the engine to overheat which is a potential risk of fires. It was under warranty for 5 years or 50K miles whichever came first. Today, I was notified by the dealership that my engine needs to be replaced AGAIN for the SAME ISSUE as 4 years ago. Coolant leaking into cylinder causing misfire. I was charged $1400 for repairs that DID NOT HAVE ANYTHING TO DO WITH THE ISSUES. Ford is now telling me there is nothing they can do for me and my car is safe to drive so long as I keep it filled with coolant.
