general problems of the 2019 Lincoln MKC - part 1

Engine failure TSB 19-2346, a known/common issue with this engine. The car only has 73,790 miles on it. The car started shaking when started, engine light on, empty coolant reservoir and off then parking brake came on randomly several times , and the brakes locked up twice, which resulted in going over a curb. Discontinued driving the vehicle after that incident obviously due to safety. Ford service center gave a $13,000 repair estimate. The vehicle is still at Ford and available for inspection.

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.

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.

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.

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

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.

The contact owns a 2019 Lincoln Mkc. The contact stated that while driving at an undisclosed speed, the vehicle briefly vibrated, prompting the contact to discontinue driving the vehicle. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer, who determined there was coolant intrusion into the cylinders resulting in engine damage. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. After investigating the failure, the contact related the failure to 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 83,000.

My 2019 Lincoln Mkc with a 2. 0l ecoboost engine experienced coolant intrusion into cylinder 2, leading to engine misfire, check engine light, and severe vibration. The dealership confirmed the issue and recommended a full long block engine replacement, estimated at over $11,000. This failure occurred at only 48,000 miles. This appears to be the exact issue described in Ford TSB 19-2346, which covers 2017–2019 model year vehicles with the 2. 0l ecoboost engine, including the Lincoln Mkc and mkz. The TSB acknowledges a design-related coolant leak into the engine cylinders that can cause white smoke, misfire, rough running, and warning lights. Ford’s recommended repair is to replace the long block assembly. I believe this is a widespread design defect and request NHTSA’s investigation to ensure proper manufacturer accountability.

The engine on my 2019 Lincoln Mkc (2. 0l ecoboost) suffered a sudden internal failure without warning shortly after the factory powertrain warranty expired. The vehicle had no prior drivability issues, no warning lights, and had been maintained on schedule. While driving, the engine began running roughly and quickly lost power. The vehicle became unsafe to operate and had to be towed. The dealership diagnosed the engine as having internal mechanical failure requiring complete engine replacement. I was told the failure was not due to maintenance and that the engine could not be repaired. The failure occurred only weeks after the 6-year/70,000-mile powertrain warranty period ended. This appears consistent with other reported ecoboost engine failures involving internal defects such as coolant intrusion, low-tension piston rings, or block-related issues. A sudden loss of power while driving presents a safety hazard, especially in traffic or at highway speeds. I am submitting this complaint so NHTSA is aware of this engine failure pattern and the safety risk associated with unexpected engine shutdowns on these vehicles.

Only 69,000 miles and have engine failure. Car shut down on the highway and put me and my child in a very dangerous situation. Dealership diagnosed it as coolant intrusion into the engine. Seems to be a widely known problem with the Mkc. The engine now must be replaced and the cost is more than the car is worth.

2019 Mkc - purchased from Lincoln last year used 20k. Known coolant intrusion into the engine. Clouds of white smoke in exhaust and coolant leak. Misfire. Requires replacement per TSB Ford replaced defective engines with exact same problem; customer satisfaction program 21n12 certain 2017-2019 model year fusion and escape vehicles equipped with a 1. 5l gtdi engine – short block replacement after coolant intrusion, program terms this program provides a no-cost, one-time repair (if needed) to the 1. 5l short block, due to coolant intrusion to the cylinder bores, for 7 years of service or 84,000 miles from the warranty start date of the vehicle, whichever occurs first. . . . . . . . . . . . But has not helped Lincoln customers with the exact same issue.

Was uninformed about previous recalls to this same make and model that took place prior to me getting this vehicle. Was told by Ford dealership recently once I took the vehicle for diagnostic for engine light being on that coolant has been leaking into the engine and would require a brand new engine. This has been a manufacture issue that Ford has been made aware of years ago and has done absolutely nothing about.

I started my car with no prior warning light or malfunction alerts on my dashboard or Lincoln phone app. Upon shifting into drive, the vehicle began shaking severely, accompanied by a loud rattling noise for the first time. I had the car towed to a Lincoln dealership, where they evaluated the issue (see attached file for their conclusion). Seeking a second opinion, I had it towed again to an independent service center, where they determined that a cracked electrical plug caused a transmission fluid leak. The defect put our safety at risk, as I was unknowingly driving with transmission fluid levels below the minimum and blackened oil. As a result the transmission had to be replaced.

Coolant intrusion to cylinder in the engine.

Engine misfires, using up antifreeze po302 po316 took to dealer, wanted to replace engine but I am 3 months out of warranty.

My Lincoln Mkc 2019 2. 0 ecoboost with just 37k miles show and engine light. Dealership diagnostic was pc0301. Misfire on the cylinder number 1. The solution? engine replacement with a cost of $9,000 usd. Due to a well know problem. Coolant leak. I can not afford to pay this amount, and unfortunately the vehicle is not under warranty. Ford motor company knows this issue and still isn’t doing anything to help owners that are out of warranty. Surely is not a problem cause by the user, is a defect from factory. This problem also affects canadian market and mexico.

Vehicle shaking when trying to start with me and my children in vehicle. Error code misfire of cylinder 1 and then smoke from exhaust. Just had it repaired in July.

Misfire of cylynder 1 and then had it replaced. Still losing coolant and rough start intermittently. White smoke from exhaust.

The coolant/ transmission fluid is found to be leaking into the engine. Now I to pay for a new engine when I have had the car 1 year and 8 months. I still owe $22,000 on the vehicle, and while it’s said that Lincoln knew about this problem, no recall was ever issued. I am 3,000 miles over the warranty, but there are no security message popping up to say this is a problem. The dealership said nothing is firing of to warn of a problem in the computer either. I had the oil changed 1 month ago but was not told or warned of an engine defect either ( I was under mileage that time). I am asking for assistance to replace this engine. I feel there should have been a recall to replace the models effected. Others have had their engines replaced free of charge I asking to extended that same courtesy free of charge. And a recall should be issued for theses bad engines when the problem was known prior to sale. I have purchased Ford vehicles in the past and but I was married at the time but he too has a lmkc right now. Please advise on some type of assistance. Thank you.
