2017 Lincoln MKC engine problems

“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…”

“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.”

“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.”

“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”
