general problems of the 2019 Lincoln MKC - part 2

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.

My car has been in and out of the shop since I purchased it, while still under the company’s warranty. I have went months without my vehicle at times. I feel these issues were directly related to a known engine failure/faulty engine by the manufacturer. My car was in a shop for nearly two months due to a rough idle without any diagnosis because it wasn’t producing a code. I brought the vehicle back in around a month later due to the same rough idle and was told the vehicle needed a new purge valve. Currently, my vehicle is at a Ford dealership waiting for a new engine to be installed. My vehicle was misfiring at start up, but my check engine light never illuminated. My coolant reservoir was completely empty. I found out that coolant was leaking into the engine compartment. I have been without my vehicle for a month now. At minimum Ford/Lincoln should be reimbursing the cost of my replacement engine since this is a known issue. Overall, I feel this should fall under a recall. I have a two year old daughter and driving this vehicle was a safety risk. Had I known about these issues I would not have purchased the vehicle. Ford/Lincoln failed to disclose that these vehicles have a defect that causes coolant to leak into the engine’s cylinders, which can cause corrosion, oil dilution and contamination, and engine failure. Ford/Lincoln failed to disclose these defects create a safety risk, because the lack of coolant created by the leaks causes overheating and can result in the cylinder head cracking, total engine failure, and/or engine fires.

One morning I started the car and it was running rough. Soon after the engine light went on. We contacted the Ford dealership and they advised us that they could not examine the vehicle until next week and advised us to go to the local car dealership who would run a diagnostic and we code take the results to the dealership and they would check the error code for what may be causing the engine light to come on. We took the car to a local car parts store who ran a diagnostic then took the error code to the local Ford dealership who informed us that the error code showed a problem with misfire of some kind and they could not look at the car until the follwowing week. The dealership stated it was okay to drive the car until next week when they can look further into the problem. We drove the car for a few days when the car showed that it was overheating. We then took the car to a car parts store near by (different from the previous car part store) who found the car was low on antifreeze and refilled the car with antifreeze. A few days later the Ford dealership examed the car and found the engine was leaking antifreeze into the cylinder. The dealership infomed us that service advisory that this was a know problem with this make and model of vehicle and stated this was a "design flaw" with this engine.

The contact owns a 2019 Lincoln Mkc. The contact stated that after the vehicle was parked, the following day, he attempted to start the vehicle, but the vehicle failed to start. The contact stated that after several attempts, the contact notified a friend, and the vehicle was jumpstarted. No warning lights were illuminated. The vehicle was not diagnosed or repaired. The contact received notification of the NHTSA campaign number: 23v378000 (engine). Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 51,000.
