2019 Lincoln Mkc

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 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.

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.
