2019 Lincoln Mkc

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.

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.

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.

The contact owns a 2019 Lincoln MKC. The contact received notification of NHTSA Campaign Number: 23V378000(Engine); however, the part to do the repair was not yet available. No further information was available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.
