2018 Ford Escape

Coolant Leaking into Cylinders: 1.5L EcoBoost engines are known for head gasket failures that allow coolant to enter the engine cylinders, which can cause white smoke from the exhaust, "low coolant" warnings, and cylinder misfires. Engine Overheating: A lack of coolant, often with no visible external leaks, causes the car to overheat suddenly, sometimes leading to engine failure.

My 2018 Ford Escape equipped with a 1.5L EcoBoost engine experienced complete engine failure due to coolant intrusion into the engine cylinders on 3/29/26. This is a known design and manufacturing defect in the engine block, documented by Ford in Technical Service Bulletins 19-2375, 19-2346, 22-2322, and 22-2134, and addressed under Customer Satisfaction Program 21N12 (GTDI Engine – Short Block Replacement After Coolant Intrusion). Ford performed a preventive software update under CSP 19B37 on this vehicle, confirming that Ford identified this VIN as having the at-risk engine. Despite this measure, the engine failed from the exact defect 19B37 was designed to prevent. The engine block’s thin-walled cooling passages between cylinders cracked, allowing coolant to enter the combustion chambers, causing misfires, overheating, and catastrophic engine failure. This engine failure occurred without adequate warning while the vehicle was in motion. Sudden loss of engine power on public roads poses a serious safety risk to the motorists and pedestrians. Ford’s own TSBs describe this as a progressive failure, but coolant loss is internal and may not trigger warning lights until the engine is already critically damaged. Ford has addressed this defect through multiple TSBs and a Customer Satisfaction Program for some VINs, but has not issued a formal recall covering all affected vehicles. Thousands of 2013–2019 Escapes, Fusions, Edges, and Lincoln MKC/MKZ vehicles with 1.5L, 1.6L, and 2.0L EcoBoost engines remain on the road with this defect. A class action lawsuit has been filed regarding this issue. I urge NHTSA to investigate and require a formal recall. This vehicle was purchased used from an authorized Ford dealership at 54,677 miles ( 7/2/2022). The dealer had full access to Ford’s OASIS system and did not perform the CSP 21N12 short block replacement or disclose the known coolant intrusion defect. As the owner, I was never notified by Ford or the dealer about 21N12.

Ford Escape has experienced coolant intrusion into the engine cylinders, a known issue affecting this model year. The vehicle began misfiring and consuming coolant without external leaks. The dealership confirmed a Technical Service Bulletin applies to my VIN. This defect can cause engine failure while driving, creating a serious safety risk. The engine shudders so bad I cannot drive the car. I have also had to replace the transmission a few years back. It became a safety hazard. I was driving it and it wouldn't get up to speed and it was stalling on the road with traffic. This vehicle has several know issues, the cost to upkeep and constantly replace things to maintain safety is unaffordable for anyone. Children and people ride in these cars. These cars are unsafe to be on the road for those in them and around them. I still owe money on mine and can't even drive it due to its safety hazards with the engine and the coolant intrusion. I do not have a repair invoice as I decided to not drop anymore money into this car. Its unfortunate I am still paying on the loan for it.

Starting in Oct or Nov 2025 I noticed that my car was not starting right away when i put the key in the ignition, then a couple of weeks later my car began to shake when i started to drive and then would stop. My dad who is a retired mechanic stated that i was low on coolant, so he filled it and the car stopped shaking and drove fine, then the very next day the car would not start right away and it began to shake, my dad checked and the coolant was low again. We filled the tank back up to the correct level and the car stopped shaking. A couple of days later the car began to shake again and the coolant was low this went on from 2025 to March 2026, i took the car to the ford dealership and they stated that i have a coolant intrusion in cylinder 2. I can not drive my car due to the shaking and car not starting correctly.

My 2018 Ford Escape, which has experienced catastrophic engine failure due to the well-documented coolant intrusion defect in the 1.5L EcoBoost engine. In early March 2026, without any prewarning or engine light, my vehicle displayed an “Engine Fault Service Now” warning and stored diagnostic trouble code P2601 (Coolant Pump A Control Circuit Performance/Range). I immediately took the vehicle to Bidwell Automotive in [XXX] , where on March 10–11, 2026, technician Gannon performed a thorough inspection. The findings were as follows: the coolant level was critically low; the water pump showed signs of leaking; the top of the piston in the affected cylinder appeared washed clean (a hallmark of coolant entering the combustion chamber); and the technician detected an odor consistent with combustion gases in the cooling system. The diagnosis was a suspected failed head gasket consistent with internal coolant intrusion. I then brought the vehicle to Future Ford Lincoln of Roseville, your authorized dealership, on March 12, 2026 (RO #XXX, Service Consultant [XXX] , Certified Technician [XXX] ). Future Ford verified the coolant intrusion into Cylinder 2 by removing the spark plugs and performing a borescope inspection. The dealership’s own technician referenced TSB 22-2322 and recommended either a short block replacement ($9,396.45) or a long block replacement ($13,331.01). The dealership confirmed that my vehicle has no remaining warranty coverage and offered no assistance beyond the paid repair estimate. Ford’s Documented Knowledge of This Defect Ford Motor Company has long been aware that the 1.5L EcoBoost engine in 2017–2019 Escape vehicles suffers from a structural design defect in the engine block’s cooling passages that causes coolant to intrude into the cylinders. Ford’s own actions confirm this knowledge. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
