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.

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.

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

- Absecon, NJ, USA

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.

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.

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.

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.

- Secane, PA, USA

Coolant leaked into the emgine block that resulted in the engine being damaged so it needed to be replaced at my expense. The car was purchased on July 2022 and only has 17500 miles on it. This is a know problem with many Lincoln kmc's. I think Lincoln should pay for engine replactment.

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.

engine misfires, using up antifreeze PO302 PO316 Took to dealer, wanted to replace engine but I am 3 months out of warranty

- Dunnellon, FL, USA

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.

- Albuquerque , NM, USA

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

The contact owns a 2019 Lincoln MKC. The contact stated while driving at an undisclosed speed, the vehicle overheated. The contact allowed the vehicle to cool down and restarted the vehicle; however, the temperature level immediately registered from cold to hot. The contact stated that the failure reoccurred three times and the process was repeated; however, the vehicle remained inoperable. The vehicle was towed to the dealer where it was diagnosed with a failed engine. The contact was informed that the engine needed to be replaced. The contact stated that when the temperature level was hot, coolant was leaking into the oil, which caused the engine to fail. The vehicle was not repaired. The manufacturer was made aware of the failure and agreed to pay a portion of the cost to repair the vehicle. The failure mileage was approximately 74,000. The VIN was unavailable.
