The coolant intrusion into cylinder #2. Very well known problem with Ford EcoBoost engines. This car has the 2.0L engine and there hasnt been a recall on it yet. It becomes a safety concern when the problem gets bad enough to allow oil to leak, causing a engine fire. The problem was diagnosed by a Lincoln dealer. No, it was not inspected by the manufacturer but my dealer did communicate the issue to Ford. There were check engine lights because this causes a cylinder misfire as the coolant leaking into the cylinders is burned. We already had the problem repaired by replacing the engine long block assembly which cost $8176.93.

There is a huge problem with my vehicle it started leaking coolant into the cylinder. The vehicle is using coolant and burning it through the exhaust. This defect in the engine block causes catastrophic failure if occuring during driving on highway can cause accident and fire.

Lincoln/Ford knowingly designed an engine where the head gasket is unable to properly seal and overtime causes intrusion of coolant into the cyclinder causing overheating. This results in the need to replace the ENTIRE engine block. They are aware of the issue and continued to build these engines with the KNOWN safety issue from 2017 - 2020 on not only Lincolns but Fords. The dealerships are aware of the issues, the corporate companies are aware of the safety issues and still there is no recall on these. They wont even help pay for the new engine. My car only has 43,000 miles on it! I should not be replacing an engine already for this known safety issue. This should be recalled immediately. I was driving my young children 3 and 1 around when the coolant overheated and it could have or ceised as I am driving or caught on fire. Someone should not have to die in order for a recall to happen. Lincoln/Ford need to make this right before someone dies. They knew of this issue when they designed it and continued to make them until 2020.

Started with a rough start in the morning. Check engine went on and took to Advanced Auto to have code checks: P0302 1/3 Stored Cylinder 2 Misfire Detected DTC Severity 2 of 3. Repair immediately if drivability issues are present. Threat to essential. I immediately went to our Ford Dealer who has been maintaining our vehicle. First thing they did was open the hood and told me to keep an eye open for the antifreeze level. He then told me that they have problems from 2017-2019 with these 2.0L Ecoboost engines - Coolant, white exhaust smoke and/or Illuminated MIL. He stated that they do not fix this engine, and provided me a 13 page report and wrote and estimate for $6,500 + tax to have the engine replaced. I have 60,000 miles on my 2017 Lincoln MKC. I drive 14 miles to work and back 3 times a week. I baby this car. This engine should not need to be replaced after 60,000. I bought the car in 2020. On December 19, 2019, Ford has technical service bulletin #19-2346 and it appears that do not disclose this to avoid fixing under their 6 year or 70,000 mile warranty. This is really unacceptable on Ford's part. Shame on Ford for not creating a recall for this engine failure. We customers should not have to pay for a newly designed engine after Ford knew that this engine was a failure. I am demanding Ford to look into this engine problem. This is unacceptable!!! I am requesting for Ford to pay for my newly redesigned engine. Bill Ford has a statement on Ford Motor Company's website: We see no conflict between business goals and social and environmental needs.

A great one delivers excellent products and services and strives to make the world a better place.

I purchased 2017 Lincoln MKC new almost immediately had electrical issues with it that has stayed throughout the vehicles life. At about 55,000 miles my car started acting up like it was misfiring. I took it to Lincoln and twice they said they couldn-??t feel anything. I left the car over night because it mainly happened in morning starting up and going a certain speed. Lincoln called me and said it was something with transmission and they would fix it. The problem did not get better. At approximately 70,000 miles my engine light came on and I took it to be read. It read cylinder 1 misfire. I changed out my plugs and coils and had light reset. Light came back on at 71,000 engine over heating. I added/filled engine coolant. Light came on off and it was chalked up to an electrical issue they couldn-??t find. I have had to refill my coolant several times as it drains quick in sumner heat and I have had to change my plugs and coils again. My car was recently at a Lincoln and they noted my spark plug and coils on the floor. They asked me about the radiator fluid and I explained what has been happening to my car since 55,000 miles. I was told that Lincoln is well aware that this is a problem with the MKC with radiator fluid leaking causing it to leak into out plugs, cause misfire and eventually seize the engine but there has not been a recall, leaving buyers stuck. My issue is that I went to dealership with these problems but was ignored and told it was something else. Lincoln purposly blamed the issue on something else so my warranty would be done and they wouldn-??t have to cover the cost. They knew about this issue and purposely pushed it off so they would not be responsible.

Car was misfiring, so I took the car to the dealership. There is coolant leaking into the engine cylinders and there is white exhaust smoke. They tell me that this is a known manufacturer defect. There is even a Technical Service Bulletin by ford recognizing the defect. TSB-19-2346. The repair requires the engine block to be replaced. Cost is over 6K.

Coolant leaks into the engine cause the engine to eventually breakdown and a whole new engine is needed.

Engine light came on.Noticed some hesitation. Took to the dealer. Was diagnosed as coolant intrusion into engine. Engine could have failed on the highway or exploded. After investigating & seeing other incidents like this on-line, I noticed there were fires & breakdowns that did occur. I called Ford/Lincoln to report. They are aware of issue, but would not cover the repair even though they have been aware of the issue for years. Bought my certified 2017 Lincoln MKC in 2020 with 25k miles with extended warranty; Currently has 68k miles. I had extended warranty thru Feb 2024, and was not aware it had expired. If my warranty was still current & had less than 70k miles, it would have been covered. I believe there should have been a recall on this type of engine. I believe that FORD/LINCOLN is responsible for the repair.

My engine kept misfiring upon starting and not accelerating while I was driving it. A coolant leak into the cylinder caused the engine to malfunction. I had to replace the entire engine block which cost over $7,000. The Ford repairman & service center told me that Ford had issued a service bulletin regarding this issue but then refused to pay for the engine damage. I only have 70K miles on the Lincoln.

2.0 Ecobooster engine. Coolant started leaking into engine right after an oil change at dealership. Now I need a new engine. I have researched that this is a known engine problem for Ford. We need a recall. I cannot afford a $9,000 repair for something Ford knew about.

My 2017 Lincoln mkc 2.0. My mechanic confirmed it has a coolant leak going into the engine. There is a known defect with the 2.0 engine.Which is requiring me to have to purchase a brand new engine with only 33,000 miles warranty expired 2023. The code that was present at the time was p0301. This is a safety concern this vehicle will leave u stranded and in worst case scenario dead because of engine failure. Lincoln should recall the engines on these vehicles!

In the ecoboost 2.0 models, The engine block has a failure point which Ford is aware of and coolant leaks into combustion chambers and causes misfires, constant loss of coolant, and possible total engine failure. The 1.5L engines were recalled for same exact issue. So far, Ford is unwilling to do anything about this potentially disastrous issue that affects thousands of ford/lincoln owners. Repair costs are over $9,000.

Coolant leakage into #4 cylinder due to the malfunction of the engine blocks gasket. Yes, the vehicle is available for inspection. I live in the country so if there is a breakdown the possibility of me being stranded on the highway or on some back road would be terrible. Yes, I had a mechanic look it over and confirm, Engine over heated on Saturday, daughter and son came to bring antifreeze and water. Had no idea where the coolant had gone, looked for a leak and found none. 2 days later the engine light came on, had mechanic come out and put code reader on it. The #4 cylinder we replaced spark plugs, 2 days later the engine light came on, mechanic replaced the # 4 coil. Nothing is working.

Blown head gasket

A couple weeks after recall of battery monitor sensor and an oil change was done (NHTSA CAMPAIGN ID: 23V378000) at a Lincoln dealership, cylinder 1 had a misfire and check engine light came and has stayed on. The vehicle has 61,000 miles and I am now told, by the dealership, it has coolant intrusion. Again the vehicle was taken to the same Lincoln dealership that did the original work. Research seems to show the 2017 Lincoln MKC has a known issue. Ford has technical service bulletin # 19-2346 released 19 December 2019 and it appears that do not disclose this to avoid fixing under their 6 year or 70,000 mile warranty. They redesigned the 2.0L ecoboost engine in 2020. Our engine could fail and put our 3 year old son at risk of injury.
