2019 Lincoln Nautilus Engine

Component: Engine Vehicle: 2019 Lincoln Nautilus – 2.0L EcoBoost Mileage at failure: ~76550 Incident date: August 2025 Narrative (paste this): My 2019 Lincoln Nautilus equipped with the 2.0L EcoBoost engine experienced a sudden low-coolant warning followed by rapid overheating and complete engine shutdown in August 2025 at approximately 70,000 miles. After adding coolant, the warning immediately returned and the vehicle entered reduced-power mode and became inoperable within about 20 miles, requiring towing. An independent repair facility performed diagnostic testing confirming coolant intrusion into the engine cylinders, internal engine failure, and coolant pooling in the cylinder head area. Diagnostic trouble codes included P0217, P0316, and P0128. The engine and turbocharger required full replacement at a cost exceeding $6,900 paid out of pocket. This failure matches Ford Technical Service Bulletins TSB 19-2172 and TSB 19-2346, which acknowledge coolant intrusion in 2.0L EcoBoost engines requiring long-block replacement. The failure created a serious safety hazard because the vehicle overheated and shut down during travel in extreme Arizona summer heat, leaving occupants stranded for hours awaiting a tow truck. This appears to be part of a widespread known defect involving coolant intrusion in Ford 2.0L EcoBoost engines. I am reporting this for safety investigation and defect tracking.

Car consistently jerking as soon as you accelarate. The acceleration takes along time to pick up speed.Can feel the car missing gears or slipping while driving even on the freeway.

The contact owns a 2019 Lincoln Nautilus. The contact stated that while parking the vehicle, the vehicle stalled. The contact was able to restart the vehicle however, the failure recurred while parking the vehicle and while at a complete stop. The contact stated while driving 60 MPH downhill, a coolant message was displayed. The contact decelerated and drove to the residence. The contact's neighbor assisted the contact in adding coolant to the vehicle. The contact stated while driving to an independent mechanic, the contact noticed white smoke coming out of the exhaust pipe. The mechanic diagnosed that the engine was blown due to coolant intrusion in the cylinders and needed to be replaced. The mechanic ordered the part and replaced the engine. The vehicle was then taken to the dealer to be reprogrammed; however, the dealer informed the contact that the new engine had failed due to coolant intrusion in the cylinders. The dealer determined that the engine needed to be replaced and ordered the part. The vehicle was not yet repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 38,000.

The component that has failed is the Transmisson. The vehicle is available for inspection upon request. We are at risk of being stranded on major highways with small children every day. This vehicle problem has been inspected by both the dealer and two independent service centers. There was one symptom noted that behaved like there may have been water in the gasoline tank. After several attempts to solve the problem, including a Tune-up, we began to see symbols that suggested a more severe problem. These symptoms began the Spring of 2024. There are still warning lamps, messages and frightening symptoms that have resulted from this system failure. I LOVE my vehicle. Imagine my disappointment to learn that many FORD vehicles are under a "silent recall" for such repair that the company is well aware of, yet you sold me this vehicle anyway. Please notify me that you will replace the Transmission or give me full trade in value toward a 2025 Lincoln Nautilus. Our family has been a FORD family for many years. We'd like to remain. What can you do? Thank you for your careful consideration.
