2017 LINCOLN MKC Complaints

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.

Check engine light on. Codes P0316, P0300, P0301, P0302. Technician confirmed via scope coolant intrusion on cylinder 1 and 2. Technician stated it is known issue with this engine and recommends a new engine for $16,169.92. This has been an ongoing issue for the past two years.

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.

Coolant intrusion into number 2 cylinder requiring full engine replacement of my 2017 my 2.0l eco boost engine

Head gasket failure where engine coolant leaked internally into the engine cylinders.

For the last 17,000 miles, the engine light has been on. We got it checked out and there is coolant and cylinder three we change the cylinder thought it was a misfire, but the problem keeps occurring and we found out information that those engines are bad.

Check Engine Light present. Took car to Ford dealership. Formal diagnosis from Ford dealership: Coolant intrusion present causing misfires, specifically in cylinder 4. P0304 and P0316 codes present. This is a known manufacturing issue; however, Lincoln customer service refuses to acknowledge the problem even exists. Upon talking to the Ford dealership service members, they stated that this is a common issue. One of the service members stated he has already dealt with multiple vehicles with this exact problem this week alone. Having an engine (misfire, steam, etc) go out due to a manufacturing/design flaw, especially while driving on the highway, is a major safety issue. Service team instructed me to no longer drive vehicle which would cause catastrophic damage.

I am filing a formal safety complaint regarding my 2017 Lincoln MKC equipped with the 2.0L EcoBoost engine (VIN: [XXX]). The vehicle has experienced a severe, progressive engine failure caused by internal coolant intrusion into Cylinder 1, directly matching the structural design defect detailed by the manufacturer in Technical Service Bulletin TSB 22-2229. This defect allows pressurized engine coolant to continuously leak directly into the combustion cylinders while driving and during engine rest. This creates an immediate safety risk of vehicle hydro-locking during ignition, sudden mid-drive engine stalls at highway speeds due to severe misfires (Fault Code P0301), and unexpected engine overheating. The manufacturer has knowingly built these open-deck engine blocks with narrow coolant grooves prone to fracturing, creating an ongoing risk of sudden thermal failure and power loss in active traffic.

Contact owns a 2017 Lincoln MKC. The contact stated that reversing at an undisclosed speed, the rear cross traffic warning system of the vehicle was inoperable. The dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was not made aware of failure. The failure mileage was approximately 36,000.

Check engine Light P0302 Engine Misfire Cylinder 2. I noticed Low Coolant in the overflow tank. Went to dealer They did a pressure test found coolant Intrusion inside Cylinder 2 open TSB 22-2229 Car or SUV if coolant gets into cylinder can cause engine failure
