2018 Ford Edge

This is an issue that could lead to sudden engine failure while driving, causing a serious accident risk. A few months ago the engine sputtered while idle after starting and the heater wasn't working well. Noticed coolant was a low and topped it off. The issue seemed resolved after this. A few weeks ago the check engine light came on indicating a misfire in cylinder 2. We changed the spark plugs, but the issue returned shortly after. We swapped coil packs, but the issue returned, still for cylinder 2. We noticed at that time the coolant was very low. There were no puddles of coolant seen underneath the car in its usual parking spot. Pulled the spark plug and noticed white residue on the end of it. The vehicle was taken to a Ford dealership where we were informed there was a crack leading to coolant intrusion into cylinder 2, requiring engine replacement at over $10,000 cost. Online research has found this is a known issue affecting multiple Ford/Lincoln models spanning several model years and Ford has a few Technical Service Bulletins (#19-2346, 22-2133 and 22-2229) regarding it. This was not communicated to vehicle owners as a possible issue to have checked out. This problem will lead to inevitable engine failure. If this happens while driving, it could cause an accident as the vehicle could just come to a stop, possibly in the middle of an interstate highway.

Approximately 3–6 months ago, my 2018 Ford Edge (2.0L EcoBoost, ~86,650 miles) began exhibiting symptoms including repeated coolant loss requiring frequent top-offs with no visible external leak, a check engine light with misfire codes, and rough idle and rough running conditions. I brought the vehicle to a Ford dealership for diagnosis. The dealership confirmed coolant intrusion into the engine cylinder, consistent with the known defect described in Ford Technical Service Bulletin (TSB) #22-2229. The recommended repair per the TSB is a full long-block engine replacement, quoted at approximately $13,000. This issue affects 2015–2018 Ford Edges equipped with the 2.0L EcoBoost engine and is the result of a documented design flaw in which channels scored into the cylinder head allow coolant to degrade the head gasket seal and enter the cylinders. Ford redesigned the engine around 2020 to address this flaw but has not issued a recall or provided remediation for affected owners. My vehicle is out of warranty and Ford has declined to cover the repair despite acknowledging the defect in the TSB. I am filing this complaint to add to the documented record of this defect and urge NHTSA to investigate and require a recall. Coolant intrusion can lead to complete engine failure, overheating, and fire risk — posing a serious safety hazard.

The check engine light came on while the vehicle was being driven during a vacation. This happened after the vehicle had a maintenance-required tune-up performed by the dealership on May 19, 2026. The vehicle was not having performance issues at the time, but I did not want to drive home with the check engine light on. The very next business day, I took the vehicle to the dealership for inspection. The dealership advised me that the vehicle had coolant intrusion involving cylinder 4 and that the engine would need to be replaced. Because this was a serious diagnosis, I then took the vehicle to another reputable automotive repair shop for a second opinion. That shop also advised that the engine needed to be replaced due to the coolant intrusion issue. This creates a safety concern because coolant intrusion can lead to misfires, engine damage, overheating, loss of power, stalling, or engine failure while the vehicle is being driven. I was more than 250 miles from home and had to avoid driving the vehicle because of the risk of further engine damage or possible failure on the road. The vehicle is available for inspection upon request. The issue was inspected by the dealership and by an independent automotive repair shop. No crash, fire, injury, or death occurred. The check engine light came on while driving during a vacation. No other warning message is known at this time.

The check engine light came on 2 weeks ago, and I have had rough cold starts since then. Brought my car to the dealership after Autozone scanned the code and told me I need new spark plugs and an ignition coil. The mechanic at the Ford dealership determined that Coolant is leaking into the cylinders - I am being told I need to replace the whole engine. Apparently, this is a very common issue with my car, as well as many other Ford models

The engine continually exhibits cylinder #2 misfiring, disappearing coolant, and rough idling. Efforts have been made, but these issues relate directly to a cracked block allowing coolant into the combustion chamber. The car has about 93,000 miles on it and has been meticulously maintained, but still the issues are getting worse and more frequent.

The car is a 2018 Ford edge titanium 2.0L Eco Boost engine.After 75,600 miles the check engine light came on. After a local auto repair shop diagnosed the problem as a coolant contamination in cylinder 3, I was instructed to take the car to a Ford dealer because a new engine was needed. The dealer confirmed the coolant intrusion in cylinder 3 and a new engine has been ordered. After calling Ford Care, I was told that this is a known problem but because my warranty had expired there was nothing Ford would do. So I will need to spend $8,500 for the new engine and installation.

This 2018 Ford Edge of 65, 775 miles was loosing antifreeze, releasing white smoke out exhaust and would throw codes of overheating issues etc. Took vehicle to Pettus Ford in Fredericktown, Missouri for diagnostic of codes. It was noted that these codes are all related and owner must get a new engine to fix the problem. No other remedy was suggested. This seems to be a none problem with this year of vehicle with no recalls noted to date. There were a few different warning lamps that were displayed to notify owner.
