2019 LINCOLN NAUTILUS — Problems, Recalls & Safety Data

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.

Component: Power Train / Transmission Vehicle: 2019 Lincoln Nautilus – 8F35 transmission Mileage first noticed: At Test drive and purchase (~61,405 miles) Status: Ongoing defect My 2019 Lincoln Nautilus has exhibited persistent hesitation, jerking, and harsh engagement during acceleration from a stopped position since the time of purchase at approximately 61,000 miles. The condition occurs repeatedly during normal driving and was reported to a Lincoln dealership service department, which stated the concern could not be duplicated and later described the behavior as “normal for that model.” The drivability problem has never been repaired and continues to occur. Ford has issued multiple Technical Service Bulletins relating to harsh shifting, shudder, and drivability concerns in vehicles equipped with the 8F35 transmission, indicating manufacturer awareness of the condition. The hesitation and jerking create a potential safety concern when entering traffic or accelerating from intersections because vehicle response is delayed and unpredictable. I am submitting this complaint to document an ongoing transmission defect affecting safe vehicle operation.

Transmission is jerking at speeds around 25mph.

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.

While driving, the entire dashboard and instrument cluster intermittently go completely blank, disabling visibility of speed, gear position, warning lights, turn signals, and other critical information. The failure occurs suddenly and without warning. The cluster then goes through multiple reboot cycles, sometimes several times in a row. In many cases, normal operation does not return until the vehicle is fully shut off and restarted. This creates a serious safety risk, especially at highway speeds or at night. The issue first occurred around 71,000 miles (Oct 2024) and has recurred multiple times. The most recent incident occurred on Oct 31, 2025 at approximately 84,200 miles. The vehicle has been to a Lincoln dealership in Raleigh, NC for four repair attempts (Dec 2024–Oct 2025). Multiple electrical modules have been replaced (battery, fuse junction box, trunk module, telematics module, keyless entry keypad), and Lincoln engineers were consulted, but the defect remains unresolved. No diagnostic trouble codes were stored during the most recent failure. The vehicle is currently covered under a Lincoln ESP PremiumCARE warranty through 2030, and the defect remains intermittent and unresolved.
