Coolant intrusion on the third cylinder causing over heating and engine failure. Known design flaw by Ford and they only offered a customer service program and not a full recall.

- Hemet, CA, USA

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.

Coolant leak/known engine issue is now effecting my car. 3/31/26 my mechanic said to take it to an engine place as it will need a new engine due to this known fault. I am too late for their extended warranty which I was never notified of, including when I purchased the car in 2021 when the issue was already well-known.

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.

Car had a weird sound and was misfiring so was taken to a shop who diagnosed with coolant intrusion issues. This has been so much headache this car has so many issues with coolant intrusion and it-??s a safety issue since it is coolant IN THE ENGINE which can cause so many issues. this needs to be fixed

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)

Safety Risk: The vehicle suffered a sudden loss of power while driving. Without any warning light or prior symptoms, the car began "pulling". I was advised by mechanics that the vehicle was unsafe to drive due to the severity of the misfire. After two expensive spark plug repairs in six months, the engine light finally triggered during a trip, revealing that the internal defect was significantly worse than a simple maintenance issue. The problem began with a sudden, violent engine hesitation. A scan revealed a Cylinder 3 misfire (P0303), but there was no initial check engine light, leaving me unaware of the danger until the car began struggling to move. Over the next six months, the spark plugs were replaced twice. Despite these repairs, the car continued to struggle with acceleration and rough idling. A final diagnosis at Palmetto Ford confirmed coolant intrusion into the cylinders (TSB 22-2322). The engine is consuming coolant internally, which fouled the spark plugs and led to a mechanical failure leading to get over $11000 on repairs for a new engine.

With only 122,000 miles on the vehicle, the Escape is generating an error associated with a misfire in cylinder 1. New plugs were installed for the entire engine and the coil in cylinder 1 was replaced. A few days later, the error was generated again with an added warning to Server now. The service station that did the previous repair, stated that this was a known issue with this Ford engine and the Escape would need a new engine. If I don't replace the engine, this vehicle has been known to discontinue working while driving. The estimate for repairs are $10,300.

I went in to get a tune-up on car because a engine light came on which was a misfire. The mechanic had a hard time getting out one spark plug with a hard residue on it. I drove for a couple days after tune-up and engine light came on again. I then started the next day the garage filled with white smoke with a real weird smell. The car showed another engine light that said Engine fault service now. Car would not start. It was towed to Ford dealership. It is a coolant intrusion into the block. I have 110,000 on vehicle and had the 100,000 extended warranty. I now I need to fight Ford to get fixed. This is a known issue and there was not a recall on this. I am retired and I am forced into buying another vehicle on a fixed income. If Ford does not fix this, i will join the class action suit that will be heard in June 2026. I have bought Fords all my life and I am super disappointed that Ford did not recall this motor and replace. I have heard that alot of people with this problem with coolant intrusion in block if over 84,000 or 7yrs Ford will not replace. Shameful when they know there is this issue.

The engine has a coolant intrusion problem with a rough idle and potential for complete failure. This problem is documented as a known problem with this engine and Ford has in the past provided extended warranties including engine replacements. Ford had earlier released TSB 20-2100 and has acknowledged the problem.

- Seneca, SC, USA

At approximately 46,000 miles our 2018 Ford Escape experienced coolant intrusion in cylinders 2 and 3. The car has the 2.0 Liter EcoBoost engine. The car was out of warranty, requiring us to pay for the majority of the nearly $9,000 engine replacement. Additionally, we did not have the use of the car for over three months. We found that this a common problem with these engines throughout the Ford model lineup.

I am reporting a confirmed safety defect in my 2018 Ford Escape equipped with the 1.5L EcoBoost engine involving engine coolant intrusion into the cylinder bores. This appears to be a manufacturing defect associated with this engine design rather than a maintenance issue. I have exercised proper diligence as the vehicle owner and have two prior inspection reports (available upon request) that showed no indication of this issue before the failure occurred. I have a formal written diagnosis from a Ford Service Center confirming internal engine failure consistent with Ford Technical Service Bulletin (TSB) 22-2229. This defect allows engine coolant to leak into the cylinder bores, which can lead to misfires, overheating, severe internal engine damage, and eventual engine stalling or complete loss of engine power. This condition presents a serious safety hazard because it can cause sudden and unpredictable loss of engine power while the vehicle is in motion, including at highway speeds. A sudden stall in traffic significantly increases the risk of a crash and endangers the driver, passengers, and surrounding motorists. Ford-??s Customer Satisfaction Program 21N12 does not adequately address the severity of this defect. All these vehicles like mine even at only 101,000 miles are at risk with no warnings. Numerous owners have reported the same coolant intrusion failure in vehicles equipped with the 1.5L EcoBoost engine, suggesting a systemic manufacturing issue. There are also ongoing consumer complaints and civil litigation related to this defect. Because this issue has the potential to cause sudden loss of power without warning, I respectfully request your Administration investigate this defect and consider a mandatory safety recall to protect the entire public. Thank you.
