Related to previous recall [xxx] I had the recall repair done. But my car with only 86,744 miles now has coolant in cylinder 3 and it's misfiring so badly the car shouldn't/can't be driven. Dealership says the entire engine needs to be replaced. I have never had a car this low of mileage that an entire engine needed replacement. This is a design flaw in the 2. 0 ecoboost and I now have a probably $20,000 or whatever it may have been worth when it ran. . . Paperweight. It's just sputtering and spitting out loads of smoke as described in original TSB. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The check engine light came on and car started to over heat when taken into shop was told need to replace entire engine this is a known issue in these make / model cars with these engines and it is not being addressed.

Purchased a 2019 Lincoln Mkc from Mazda and stokes on ashley phosphate in north charleston, south carolina. I was told that the vehicle had recalls and they identify the recalls about the battery and the rear camera when I asked was there anything else wrong with the vehicle, they said no when I drove the vehicle home after a few days the engine light came on. After doing some diagnostics at the dealership, it will discovered that there was a misfire in the engine. They did a complementary repair. It took a couple of days when I received the vehicle. I took it home and after about a week, the engine light came back on for the same problem after further diagnostic come to find out that if this problem persist is because of coolant intrusion come to find out that this is common among engines that are 2. 0 l eco boost engine engines in the 2019 Lincoln Mkc. I am making a complaint because I found out also that I will not get reimburse my money. Neither will they take the vehicle back. I called the Lincoln dealership and they will not do a goodwill repair so I purchased a car about three weeks ago with them, knowing this problem and did not disclose it to me or told me about it cause this is common knowledge for this vehicle and they sold it to me and now I have payments on a broke vehicle, which I can’t afford $11,000 new engine or a long block.

My 2019 Lincoln Mkc has the widespread coolant intrusion engine defect acknowledged by Ford. This is a premature internal engine failure due to design.

Ford's 2. 0l ecoboost engine has seen recalls and technical service bulletins (tsbs) primarily for coolant intrusion leading to engine failure, affecting models like the 2017-2019 Mkc with issues stemming from a block design flaw and faulty head gaskets that allow coolant into cylinders, causing overheating, corrosion, and potential engine fires. This vehicle is confirmed to have coolant intrusion in the cylinders, resulting in premature engine failure.

The contact owns a 2019 Lincoln Mkc. The contact stated that the messages "service advancetrac", "hill start assist not available", "system off - to save battery please turn off ignition or start engine" were displayed. The vehicle was taken to the dealer, where it was diagnosed, and determined that the battery and the battery monitor sensor had failed and needed to be replaced. The parts were ordered to repair the vehicle. The vehicle was not yet repaired. The contact related the failure to NHTSA campaign number: 23v378000 (engine); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 98,000.

Vehicle overheated, due to collant entering #1 cylinder. This coolant intrusion is apparently a well documented issue, from an acknowledged engine defect. (TSB 19-2346, TSB 22-2133) Ford dealership recommended an $11,000 + tax engine replacement, with no relief, as car is past its warranty. The vehicle has 58540 miles. Lincoln customer service also declined any goodwill repair. Independent service dealer (craig’s auto repair service 281-469-5949) first diagnosed the issue, recommended taking the vehicle to Ford dealership (tomball Ford).

Engine warning light went on. Replaced spark plugs and coil to cylinder # 2. Then, traction control light indicated system off. Technician advised the need for dealership software upgrade to abs. Dealership advised that engine block allowing coolant intrusion into #2 cylinder. Needs a new engine. And need for a new abs module, also defective.

I have a coolant leak and the dealership states that it's located in the engine.

Vehicle unresponsive after sitting idol at traffic light. When trying to accelerate, no power. Vehicle was still running, but unable to accelerate. Finally able to accelerate after rpms up to nearly 3000 rpms, and slow to respond and accelerate. Engine warning code on dashboard soon after. Error code is p0751, shift solenoid a performance stuck or off. Similar issue when under warranty in 2022 with 22,000 miles.

The head gasket has failed, leading to coolant intrusion into the number 2 cylinder. Several misfires occurred due to this. This is a known issue due to the design of the lower block, which uses a channel, thus causing a very small surface area for the head gasket between the channel and the cylinder, which accelerates wear. Spent $3,000 to fix this well-known design issue. Car at ~100k miles.

My 2019 Lincoln Mkc with only 52,200 miles experienced unrepairable engine damage due to an internal coolant intrusion condition that directly matches Ford TSB 22-2229. On or around Jan 1st or 2nd, a check engine warning light came on as I was driving home at night. I did not drive my car any further except to the dealership for service on 1/5/2026. The engine failure was diagnosed by the dealership on 1/6/2026. This engine failure occurred well below a reasonable engine life expectancy, and is caused by a documented design defect. The manufacturer’s refusal/delay in recalling these engines with a known design defect places drivers at risk of being stranded at any time of day or night, and drivers risk becoming a road hazard to themselves and others when experiencing complete engine failure.

The 2017 Lincoln Mkc requires a full engine replacement due to a serious, well-documented defect: coolant intrusion. This is a major issue that can destroy critical engine components, including the head gasket, cylinders, and even the engine block. Ford/Lincoln is aware of this problem. They issued multiple tsbs (22-2133 and 22-2229, to name a few), yet customers are not informed. Because there is no recall, if the car is out of warranty, dealers refuse to perform the necessary repairs unless the customer pays tens of thousands of dollars for something that is a known manufacturing defect, leaving them vulnerable to catastrophic engine failure and potential accidents, injuries or worse. This is a known manufacturing defect, and consumers should not bear responsibility for the resulting safety hazards. Ford/Lincoln must take immediate action and issue a recall before it leads to serious injuries or fatalities.

I was driving home from work on December 24th 2025 and my 2018 Lincoln Mkc 2. 3l shut off on me while I was in motion. There were several cars that had to swerve and not hit me. The car would not start but I was able to put the vehicle in neutral and roll to the shoulder of the road. I was very scared and angry because this vehicle only has 54,646 miles currently, give or take 50 miles. I had to get the towed to my home. This needs to be resolved and fird/Lincoln needs to faithfully fix this dangerous defect, I could have died. Please please do something because I do not want anyone else to deal with this.

2019 Lincoln Mkc with 96k mileage suddenly started running rough around 30mph and I was losing power as I was entering a highway on a ramp. Rpm needle was fluctuating between 2k and 3k. Immediately drove back home and towed it to Lincoln shop. They said its an issue with coolant intrusion into the engine compartment and would have to replace the engine block. Estimated at $11k. Extended warranty company said claim is likely to be denied as these ecoboost 2. 0l engines are notorious for these issues. It is a faulty manufacturing and there is no recall. Costing consumers thousands of dollars and also putting lives of passengers at risk.

My initial reason I took the car to the dealership, was because the vehicle would not want to start or stay running after fuel was put in. I aiso had a check engine light on. After the dealership performed diagnostics on it, they said the purge valve was bad which was the cause of it not starting. The check engine light was on because it was low on coolant. So I scheduled another appointment with wyatt Ford in manistee mi 49660 on Dec 1, 2025. They performed a coolant pressure test and determined that it is losing pressure after shutdown. They cannot find a leak. They removed the spark plugs, but #3 spark plug is "stuck" and they are attempting to remove it. If the spark plug breaks, they will take more of the engine apart to access it and attempt to "tap" out the threads of it. The technician (sherman) told me that the cause of it being stuck could be due to the fact of the coolant leaking into that cylinder. Sherman was able to remove the #3 spark plug and found coolant in that #3 cylinder. They are now saying that the engine does need replaced and it is not safe to drive. The service department (ava) gave me Ford customer service number to call to start a case. I called 800-392-3673 and spoke with alex. She told me she will do some further research and call me back in about two hours. It is now 12:30 pm east coast time. After returning a call from her, she said that there are no programs at this time with Ford to assist with replacing the engine. Only if there is a recall on this is when they would be able to replace it for us.

Engine failure due to known coolant intrusion defect documented under Ford ecoboost TSB guidance. Denied goodwill assistance despite defect being manufacturing-related.

Lincoln 2019 Mkc reserve head gasket problem check engine light on. Took to dealership and confirmed with compression test that it was TSB – 22–2229 had to replace engine with new long block. Lincoln corporate assistance paid some 2835. 10 I paid $4265. 05.

My car misfired, then the heat wouldn't work then started to overheat. The car is 2019 Mkc 2. 0l engine. Only 64k miles on it. I am the original owner. Took it to the dealership and they said the coolant has back up into the engine. I read that this has been a known issue with these engines and was never notified. It is going to cost 10k to replace this engine.

The 2019 Lincoln Mkc model made prior to April 2019 is part of a variety of Ford/Lincoln manufactured models that are known to have a coolant intrusion issue. This causes various issues within the engine system such as head gasket failure, cracked cylinders, and cracked engine block causing the coolant to leak and potential for fire risk. Although check engine light warning will be present, the code is presented as a misfire and the suggested fix is to replace spark plugs and coils. This will be completed, and seem to resolve this issue however, it is temporary and problems continue to persist. The car will loose power while driving and be unable to accelerate or continue to keep consistent speed such as when driving on freeway. Despite having a TSB 22-2133, customers are not made publicly aware of this issue and if they do not fit within warranty timeframe the dealer will not complete recommended service of the issue. Therefore, the customer is not at fault for the unsafe, known manufacturing issue and therefore Ford/Lincoln should make the effort in correcting this prior to serious customer injury/death.

The check engine light came on and it would run rough when started. It was determined the number four cylinder head was cracked, allowing antifreeze to leak into the engine block. I bought the car new in January 2019. The problem appeared with under 57,000 actual miles. The car has always been serviced on time at the dealership. The cost to fix the problem with a new engine is approximately $10,000. I bought the car new so that I would not have problems. It is my only form of transportation. In researching, I have found this is a reoccurring problem on the echo boost four-cylinder engine since 2017. It didn’t matter whether it was low mileage or high mileage the cracks would appear. There had been a recall on later models, but no recall for the 2018. I believe it should be under recall.

Engine seizes while driving and chokes due to engine misfire. First occurence was at 34kmiles in 9/2023 and when brought for emissions check mechanic said needed new spark plugs/coil so had them replaced for $800. 3-4months later after only 1k miles check engine light goes on again and car hums/rattles like it will stall. My brother runs diagnosis and same issue and that’s when I started to do research and found that Lincoln Mkc 2019 have known engine issues. As it was under warranty until Dec 2024, I brought to steven’s Ford in milford CT and raised this engine issue and specifically asked for full repair to ensure issue is fixed. 18 months later on 11/12/2025, while driving car the engine starts to hum and rattle feel like it will seize and check engine light goes on again. Same issue from when I had repair under warranty but Lincoln dealer claims it’s a parts issue and not an engine issue. These vehicles are dangerous and can cause accident due to engine just stopping. Dealership and Lincoln refuse to provide any support.

The contact owns a 2019 Lincoln Mkc. The contact stated that while driving at an undisclosed speed, the temperature gauge started to indicate that the engine was overheating, prompting the contact to discontinue driving the vehicle. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who determined that there was a misfire in cylinders #2 and #3. The contact was informed that the spark plugs needed to be replaced. The vehicle was repaired, but the failure reoccurred. The vehicle was not repaired. After investigating the failure, the contact related the failure to the customer satisfaction program: 21n12. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was 58,555.

Head gasket leaked coolant into the engine and now the engine is not working and needs replaced.

Coolant intrusion in engine.

Total engine failure due to coolant leak into the 2. 3l Ford motor. This is a known issue with the Ford motors and it is not covered. This eventual coolant leak makes the owner have to buy and replace the engine with one that has similar issues and costs $8300+. This is unacceptable and Ford needs to cover and address. Never had an engine do this to me before and it’s horrible. Please hold Ford accountable. Navy ad and with the shit down, this will be an expense I can not cover with 3 children, one in college. Was planning on keeping this car till the filter falls off… not anymore I guess.

My Lincoln Mkc 2017 is having a recurring problem with a misfire in the 3rd cylinder due to a hood gasket, a crack in the coolant, and leaking on the sparks and coils. I have had my mechanic work on and look at it, and it is a manufacturing defect. When I called, there was no recall listed for my vehicle except the backup camera. However, when you look at kelly blue book, it says there is more than one engine recall and issue, which is exactly what is happening to my Lincoln. The engine block heater may crack and develop a coolant leak, causing it to short circuit when the block heater is plugged in.

Car had engine light come on, was told from dealer need completely new engine despite only 70k miles. Is a known issue, please protect us consumers.

The contact owns a 2017 Lincoln Mkc. The contact stated that upon starting the vehicle, the check engine warning light illuminated on the instrument panel, followed by a coolant temperature message. The vehicle was taken to a dealer, where it was diagnosed with a hairline crack in the engine. The hairline fracture led to coolant intrusion inside cylinder #2, and the vehicle was diagnosed with engine failure. Upon investigation, the contact discovered technical service bulletins 19-2346 and 22-22229, which the contact linked to the failure. The contact called another dealer about the failure and was informed that there were no recalls on the vehicle related to the failure. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The failure mileage was 98,690.

The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. In addition, the contact referenced NHTSA campaign number: 25v685000 (equipment); however, the VIN was not included in the recall. The failure mileage was approximately 42,000.

The engine light came on. It was inspected and there is a coolant intrusion. Apparently, this was a known issue for this engine. There is an existing technical service bulletin (TSB) 22-2229 and a Ford customer satisfaction program (csp) 21n12 related to this issue the program indicates up to 7 years or 84k miles, which I believe this falls under (my mileage is 42k) providing a one-time repair program providing a no-cost short block replacement.  Ford is not cooperating.

Check engine light came on. The engine has coolant intrusion and the engine would have to be replaced, quoted me $17,240. 83 I called 888-214-2155 Lincoln client relationship center and I was told there was nothing they can do to help me. After doing some research, this has been a known problem by Lincoln and they have not put out any recalls. They also have a class action lawsuit against them.

I got out of work and went to start my car. At first it did not want to start, and it acted like the alarm system had an issue. I locked my car, then unlocked it with the key fob, and when it started, it ran rough and was smoking out of the exhaust. I turned it off and quickly checked the fluids. I noticed the antifreeze was low, and since I always carry fluids in the car, I filled up the reservoir and then tried to restart my car. It did the same thing, not wanting to start until I locked and unlocked with the key fob. I drove home, but the check engine light was on the entire time. The following morning, I started my car and it was blowing white smoke out of the exhaust. I turned it off and contacted a local auto repair shop. It had to be towed to the shop so as to not cause damage. The auto shop said it was the head gaskets and since there was a known problem with the coolant leaking, I would have to get a whole new (used) engine. The total would be over $8000. I called another repair shop to see if they would be willing to replace the head gaskets, and after they agreed, I had it towed to their shop. After diagnostics, (no negligence on my part) this shop also refused to just replace the gasket citing an ongoing class action lawsuit due to a known head failure, and the repair with a new engine would be over $9000. I had purchased an extended warranty (power train) when I purchased this vehicle, and it included seals and gaskets. . . So I thought I was covered for this problem. The warranty company refused to cover it since it was a head problem. I still have 2 years of payments left on this vehicle.
