2018 Ford Escape

I bought the vehicle used with 98,000 miles. After a few months of driving and reaching 103,000 miles is when the problem occurred. As active duty military I was in the field for 2 days. When I had gotten out of the field I started the car and was sitting there for about 2 minutes and seen the temperature gauge starting to rise. So I turned the heat on full blast and started to drive, then the temperature gauge went all the way to the hot position and went into limp mode. I turned the car off popped the hood and seen it drank all of the coolant. So I refilled the coolant and let it sit for about 24 hours. The next day i turned the key over to supply battery and seen it was still completely hot. I’ve done some research and believe I’m experiencing the beloved coolant intrusion.

My car experienced a sudden internal engine failure due to a known manufacturer design defect causing coolant intrusion into the engine cylinders. A Ford dealer service center diagnosed the issue with Diagnostic Trouble Code (DTC) P0303, confirming a Cylinder 3 misfire caused by coolant leaking into the block. The vehicle requires a total engine replacement at just ~66000 miles at a cost of over $9000. This internal coolant leak poses a severe safety hazard, including sudden engine stalling, loss of motive power while driving, and potential thermal runaway/engine fire risks. The vehicle is currently rendered unsafe to drive.

I bought a 2018 Ford Escape SEL 4WD in March of 2019 ( I think ) it already had about 1240 miles on it but was sold to me as new. At the time of purchase I also bought a 7 yr warranty because of my age. Only my wife and I drove the car. In March of 2026 the engine block failed due to a manufacturing error concerning coolant getting into the piston chambers. The SUV only had about 15,800 miles on it. The 1.5 liter eco boost engine block had to be redesigned to allow coolant to flow around the cylinders. All this info is on the internet. I never received a letter from Ford about this potential engine failure. The engine light came on and the book said take it to the dealership which I did. They diagnosed the problem as stated above. If I had not have purchased the xtra warranty I would have been on the hook for 6 or 7 thousand dollar engine replacement as it was out of the 3 yr warranty at the time of purchase. In my opinion only, my guess is that Ford gambled that the engine would last thru the initial warranty period and maybe fail some time after but this is just conjecture on my part. On top of this they lost the first block they ordered by mistake ? and had to order another which took extra weeks of waiting, then it came in and then they found problems with the phasers and camshaft and then there was a dispute I presume between the Dealership, Ford Motor Co. and the warranty people as to who would pay for what. So in the end of my statement we got our car back 12 days before 3 mo's in the shop and many calls to the service dept. and to say that I was upset would be an understatement as I was having to pay insurance for nearly 3 mo's on a car I could not drive.

I have a vehicle whose refrigeration is going into the motor. It started with the check engine light came on notifying the third spark plug was damaged and showed the codes P0303, P04DB, P0316, P0339. Later a warning sign came on the dashboard with the phrase "ENGINE MALFUNCTION, SERVICE NOW". It had a recall almost immediately after it was acquired and was seen by the manufacturer about two years.

Due to faulty manufacturing by Ford Motor Company the coolant leaked into cylinders 2 and 3 of the engine. Ford is aware of this issue and has issued a technical service bulletin stating that the only fix is to replace the engine however they have not issued a recall. The leak has been confirmed by two mechanics. Blacks Tire and Auto and is currently at the Ford dealership. The check engine light came on and I researched the code and found many stories of people having the same issue.

When checking the oil, realized that there was no antifreeze in the reservoir. I went ahead and filled it to the max line, as the antifreeze didn't even come up to the minimum line of the reservoir tank. My gut was telling me that I need to every so often check the antifreeze, there was no apparent leak, there was nothing on my garage floor to indicate that there was a leak. Every time I checked the antifreeze, it was below the minimum line. I had also been noticing that my car was shifting hard. the rpms were randomly jumping higher than normal when I was maintaining a normal speed. When I go to start my car, the whole car shakes as though the engine is misfiring. When I took the car in to a mechanic, they looked it over and I was told that I needed to replace the long engine block due to a coolant intrusion into the cylinder. The car will sometimes show the check engine light and sometimes it just goes off. I had the check engine light come up before and was told after having it hooked up at Auto Zone that I just needed a tune up.

2018 Ford Escape: engine coolant intrusion resulting in a completely failed engine. Took it to a local Ford dealership for evaluation. Confirmed this was the issued. Quoted over $14,000 to replace with a re-manufactured engine. This issue causes misfire, smoke and could catch on fire. Contacted Ford and was told while we qualify for mileage for the customer service program 21N12, it does not qualify based on expiration despite knowing this is a faulty part.
