2017 Lincoln Mkc

My 2017 Lincoln MKC equipped with the 2.0L EcoBoost has recently experienced a serious engine failure and requires engine replacement. It developed an engine problem while driving on at least two occasions and is no longer reliable or safe to operate. No prior warning messages were observed on the vehicle. Fortunately, I was able to pull over on the side of the road and I observed smoke coming from the engine. I was then concerned about the safety of an unexpected engine failure while driving, which might cause the vehicle to stop in traffic. I have now observed green/milky contamination on the engine oil dipstick. The vehicle requires further diagnostic evaluation and engine replacement by a Ford dealership. Ford issued technical service information concerning coolant intrusion into the cylinders of 2017-2019 Lincoln MKC vehicles with 2.0L EcoBoost engines. I am reporting because I believe the engine failure may be related to this condition and may represent a safety defect. I am in the process of having the Ford dealership inspect the vehicle and likely replace the engine. I can request the engine be retained for possible inspection. Ford Lincoln has been contacted regarding this problem. They denied any post-warranty financial assistance. I am concerned the failure may be related to the coolant-intrusion condition described in Ford's technical service information.

I own a Lincoln Mkc 2017 - purchased on 2/19/19 with 12miles I have replaced 4 batteries over the years so far. I drive every day. I am never sure if the car will start. Multiple times i have a dead battery. Lincoln has a problem with this module and the electrical system. parasitic drainage issues on the battery. I don't feel safe, because there is an "unknown" draining the battery, therefore I am scared to drive the car and don't want to keep getting stranded. They have discontinued this make and model, but I am seeing the same complaints with the Corsair. My car only has 53k miles, it is in excellent condition. But unfortunately, i cannot rely on this car. I don't know what to do.

My husband and I own a 2017 Lincoln MKZ that was purchase new in 2018. It is equipped with the 2.0L EcoBoost engine, with approximately 69,000 miles. It has been meticulously cared for! Before the diagnosis, I noticed that when starting the vehicle and backing up, the engine would jerk slightly until I stepped on the accelerator to proceed. The check engine light then came on, which prompted me to take the vehicle to the Lincoln dealer for diagnosis. The servicing Ford/Lincoln dealer, Sugar Loaf Ford in [XXX], examined the vehicle and found coolant in a cylinder. We have been advised that the engine requires replacement. I am concerned because this appears consistent with reported coolant-intrusion problems involving the 2.0L EcoBoost engine used in certain Ford/Lincoln vehicles. A vehicle with only approximately 69,000 miles should not require complete engine replacement because coolant is entering a cylinder. We contacted Lincoln Customer Service and opened case #XXX requesting assistance. Lincoln declined our request and closed the case. Sugar Loaf Ford also contacted Lincoln on our behalf, but Lincoln again declined assistance. I am filing this complaint because I am concerned that this may be a recurring engine defect rather than normal wear. I request that NHTSA document this failure and consider it together with similar complaints involving 2017 Lincoln MKZ vehicles, particularly failures involving coolant intrusion into the cylinders and resulting engine replacement.
