"I am reporting a severe, known manufacturing defect involving internal coolant intrusion on my 2018 Ford Edge 2.0L EcoBoost, which has caused total engine failure and rendered the vehicle entirely unsafe and completely inoperable. The vehicle began throwing codes P0300 (Random Misfire), P0302 (Cylinder 2 Misfire), and P0303 (Cylinder 3 Misfire) due to liquid coolant flooding the combustion chambers. The engine is now completely locked and will not start, stranding me at home with no transportation. This is a critical safety issue. Liquid coolant leaking into active engine cylinders poses an immediate risk of sudden engine stalling while driving, loss of motive power in traffic, and potential engine fire hazards. This failure matches Ford's own Technical Service Bulletin (TSB 22-2229), proving Ford has long-standing knowledge of this hazardous design defect. When I contacted Ford Motor Company corporate customer service for emergency assistance and towing to a dealership, Ford explicitly refused to assist me and instructed me to contact class-action plaintiff's attorneys instead. Ford is actively refusing to remedy a severe, known safety hazard for a stranded consumer. I request that the federal safety agency escalate its investigation into Ford EcoBoost coolant intrusion to force a mandatory safety recall before this defect causes a serious highway accident."

Check engine light appeared, heat stopped working, and received alerts for overheated coolant for 5 second intervals before it would disappear. Mechanic evaluation: Technician performed diagnostic inspection due to multiple engine fault codes, overheating, and engine misfire conditions. Upon inspection, technician found evidence of an internal cylinder head gasket failure allowing engine coolant to leak into the combustion chamber and cylinder wall area. Coolant intrusion into the affected cylinder is causing improper combustion, resulting in engine misfire, especially during initial start up. The internal coolant leak can also contribute to coolant loss, overheating, and internal engine damage.

The 2018 Edge has been having Engine misfires for at least 3 months. Edge has had rough starts in the AMs - Check engine has gone on and off. Two main concerns is that the issue with the 2.0 Eco boost is the coolant intrusion into cylinders causing a whole engine replacement. Currently the 2018 Edge only has 65,723 Miles Ford has quoted the repair at a cost of 11k I was prompted to take vehicle in because when I was driving on the Highway at 65mph the engine gives gives you a message the car is going to overheat - so it will automatically reduce engine power to not crack the engine block but not great when you are travelling at a high rate of speed.

My 2018 Ford Edge with the 2.0L EcoBoost engine has approximately 80,000 miles. The vehicle recently experienced a significant loss of engine coolant with no visible external leak found. The coolant level was extremely low when checked. While driving the vehicle, the engine began running very rough and the check-engine light started flashing, indicating a severe misfire. Because of the sudden change in engine operation and concern about possible engine damage or loss of power, I turned around and stopped driving the vehicle. It has not been driven normally since. The vehicle has not yet gone through Ford’s full diagnostic procedure for internal coolant intrusion. I am aware that Ford has issued TSB 19-2346 concerning coolant intrusion into the cylinders on certain 2015-2018 Ford Edge vehicles equipped with the 2.0L EcoBoost engine. Based on the severe coolant loss with no visible external leak and the subsequent misfire/flashing check-engine light, I am concerned that my vehicle may be experiencing the same condition. The vehicle is available for inspection. A Ford dealership recently inspected the vehicle for a separate flexplate concern and advised that it was not exhibiting the cracked-flexplate issue. The coolant-loss and engine-misfire condition occurred afterward. I am reporting this because a sudden severe engine misfire, overheating, or loss of engine power while driving could create a safety risk, especially if it occurs at highway speeds or in traffic.

My 2018 Ford Edge Titanium (2.0L EcoBoost) is experiencing internal engine coolant intrusion - the defect described in Ford Technical Service Bulletin 22-2229 (June 10, 2022), which covers 2015-2018 Ford Edge 2.0L EcoBoost vehicles for coolant leaking into the engine cylinders. The engine loses motive power without warning: it revs but the vehicle barely accelerates, including at road speed - a sudden loss-of-power hazard in traffic. Symptoms began approximately 09/08/2026. The check-engine light is illuminated with diagnostic codes P0300, P0302, P0303 (engine misfires, cylinders 2 and 3), P0316 (misfire on startup), P0217, P1285, P1299 (overheating - the computer has entered cylinder-head over-temperature protection mode), P0299 (turbo underboost), P0012 (cam timing), P0172 (rich condition), and P0420. This matches Ford's own bulletin identifying coolant intrusion into the cylinders, a condition the bulletin says may require complete engine (long-block) replacement. The selling dealer (JD Byrider) was formally notified on 09/29/2026 and I have requested cooling-system pressure testing and cylinder inspection. Exact current mileage is unknown - the vehicle is at the dealership.

Coolant leaking directly into the engine’s combustion chambers. Mechanical failure, not a simple leak: coolant crosses from the cooling jacket into the cylinders themselves, fouling combustion instead of regulating temperature. The defect traces to the engine block and cylinder head design, combined with a head gasket seal, inadequate. The resulting symptoms as a sudden, significant loss of power paired with an “Engine Coolant Over Temperature” warning on the dashboard, often followed by rough running once the engine cools and a check-engine light tied to a cylinder misfire. Stopped at a green light to turn left. When the oncoming traffic cleared. Hit gas and it almost stalled. Addition traffic approaching me had to slow down to avoid hitting me.

At a routine oil change visit, Akins Ford found the engine coolant low and added coolant. That had not happened before. Later, while my daughter was driving the vehicle, the check engine light came on and an engine warning message appeared. The engine lost power and the vehicle could not be driven normally. A scan tool read DTC P0303, cylinder 3 misfire detected. The vehicle was towed to Akins Ford in Winder, Georgia. On XXX Akins opened repair order 955703 and diagnosed a cylinder number 3 misfire caused by coolant intrusion into the cylinder. The dealer performed a borescope inspection and confirmed coolant in the engine. The dealer said the engine long block has to be replaced and estimated the repair at $9,051.31. The vehicle had approximately 83,931 miles. It is still at the dealership and has not been repaired. Ford issued Technical Service Bulletin 19-2346 on XXX, titled "2.0L EcoBoost - Coolant In Cylinders, White Exhaust Smoke And/Or Illuminated MIL." It covers 2015-2018 Edge vehicles with the 2.0L EcoBoost engine. It describes a low coolant level and a runs rough condition with DTCs including P0301 through P0304, states the cause may be coolant intrusion into the cylinder, and directs dealers to replace the long block engine assembly. My vehicle is within that range. My failure matches the bulletin on model year, engine, symptom and diagnostic code. I contacted Ford on XXX and asked for assistance. Ford denied assistance and said the vehicle was too old because it is more than six years old. The vehicle has under 100,000 miles. My Ford case number is [XXX]. I am reporting this as a safety problem because the engine lost power while my daughter was driving the vehicle. I understand the federal safety agency opened defect petition DP26008 on XXXcovering the 2.0L EcoBoost engine in 2015-2018 Edge vehicles. There was no crash, no fire and no injury.
