2019 Lincoln MKC Engine Problems

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.

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.

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

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 FAILURE DUE TO COOLANT INTRUSION TSB22-2229 DEALER SAID THIS TYPE OF FAILURE IS NOT COVERED BY MY EXTENDED WARRANTY AND FORD/LINCOLN CORP REFUSES TO PAY FOR THE REPAIR .

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.

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.

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.

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.

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.

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.

Coolant leak, no warning overheating car turned off,needs new engine,coolant leak into cylinder ,only 62000 miles on the car

There’s a cracked block/head gasket causing coolant to leak into the cylinders and now my engine needs to be replaced.

The vehicle has now been at the dealership for almost two weeks. I drove the car in under its own power and was shocked to learn that it needs a new engine (long block) due to a known issue described in a Technical Service Bulletin (TSB) 19-2346 After doing my own research, I discovered that this is a widespread problem with the Ford 2.0L engine, and the dealership confirmed this by stating they’ve replaced hundreds due to this defect. I then contacted Ford directly, but was told by customer service that the vehicle is out of warranty, and nothing could be done. The Ford case number is [XXX]. Let me be clear: this is not normal wear and tear. A major engine failure at only 63,000 miles is completely unacceptable — especially in a Certified Pre-Owned (CPO) vehicle, which I was sold as reliable transportation. I now realize that Ford and its dealers have been knowingly selling vehicles with a manufacturing defect, without taking responsibility when those vehicles inevitably fail. This is a documented defect in the engine block, as acknowledged by Ford in the TSB. Yet there is no recall. Why? This issue poses a serious safety risk, not to mention a massive financial burden for consumers who trusted Ford’s certification and quality standards. It is deeply concerning that Ford has chosen to avoid accountability, leaving owners like myself to pay for expensive repairs stemming from your own design flaw.

On or about July 29, 2025, the check engine light illuminated in my 2019 Lincoln MKC Sport with a 2.0L EcoBoost engine. A mechanic inspected the vehicle on August 4, 2025, and confirmed coolant is entering cylinder one, likely due to a blown head gasket or, less likely, an engine block crack. Symptoms include coolant loss, potential misfiring, and the check engine light activation. The issue was identified through diagnostic testing (e.g., borescope inspection or compression test, pending specific results). No external coolant leaks were observed, indicating an internal engine failure. The vehicle has 89,516 miles and was purchased three months ago on May 5, 2025, from Ford City in Champaign, Illinois. Safety Concerns: Coolant intrusion into cylinder one risks engine misfiring, rough idling, or sudden power loss, which could cause engine stalling or failure during operation. This poses a serious safety hazard, as it may lead to loss of vehicle control, particularly at highway speeds or in traffic, endangering the driver, passengers, and other road users. The defect compromises the reliability of the 2.0L EcoBoost engine and requires costly repairs. Additional Context: • No known history of severe overheating exists, but maintenance records prior to purchase are unavailable. • The vehicle has no aftermarket modifications. • No crashes or injuries have occurred, but the issue emerged shortly after purchase, suggesting a possible pre-existing defect. • Similar coolant intrusion issues have been reported in earlier 2.0L EcoBoost engines (e.g., 2013–2016 Ford models), and this may indicate a recurring defect in the 2019 MKC. • I urge NHTSA to investigate whether this engine issue warrants a recall due to its potential safety impact.
