2016 Lincoln MKC: misfire or rough idle

Filed May 15, 2026 · Engine · FL

My 2016 Lincoln MKC with a 2.0L EcoBoost engine experienced coolant intrusion into cylinder 3, leading to engine misfire and check engine light to turn on. The dealership confirmed the issue for $176.55 and recommended a full long block engine replacement, estimated at over $11,000. This failure occurred at 98,000 miles. Two weeks before this, the check engine light illuminated and we took it to a repair shop where we paid $628 to repair the purge valve and fuel pressure sensor, while it was most likely this coolant intrusion both times! Ford and Lincoln (including concierge) have refused any assistance in this matter. The local dealership has also said that they cannot help us with any of the cost. I've found this to be a very well documented problem/engine design failure, Including HTSA ID Number: 10162062 Manufacturer Communication Number: TSB 19-2172 entitled Components: ENGINE AND ENGINE COOLING The TSB acknowledges a design-related coolant leak into the engine cylinders that can cause white smoke, misfire, rough running, and warning lights. Ford’s recommended repair is to replace the long block assembly. In addition, this appears to be the exact issue described in Ford TSB 19-2346, which covers 2017–2019 model year vehicles with the 2.0L EcoBoost engine, including the Lincoln MKC and MKZ. I believe this is a widespread design defect and request the federal safety agency’s investigation to ensure proper manufacturer accountability. I am so thankful that this car does not belong to one of my daughters as it poses a severe safety hazard on the road and it is going to be a huge financial setback that we may not recover from.

A gasket failed which allowed coolant to leak into the engine. Due to lack of coolant, two of the cylinder heads cracked and warping of the engine block occurred. No coolant in the engine could result in a engine seizure or fire which poses an extreme risk to one's safety. The check engine light came almost immediately before the cylinders started to misfire. 11/25/2023. The vehicle and components have been inspected by the dealers service department and the warranty inspector. The car needs a full engine replacement which only half is covered under the warranty. I am out of pocket the other half. See link regarding a current lawsuit the describes EXACTLY what happened to my vehicle: [XXX] .

My car has had an engine light that comes on goes off throwing a code for Cylinder One Misfire since January 2023. It was 'repaired' at the dealership that I bought it from and they replaced the spark plugs and the coil and that did not stop the light from coming on and going on. I took it to another service center in my town and had it checked one of the times that the engine light was on and they used a camera and ran it through the system and found nothing wrong. It has now started to consume large amounts of coolant but I am not seeing a leak on the ground. I do not know where the coolant is going, I am now worried that it is going into the engine. I did purchase a warranty on the engine with the car but the Lincoln Dealership nearest to me will not accept the warranty because it is not a Ford/Lincoln warranty. I don't know what else to do am at a loss.

In 2019 I bought a used 2016 Lincoln MKC Reserve 2.0 Ecoboost Engine w 34K miles. In 4 years I've driven 11,400K miles. A few weeks ago my vehicle would not start. I had a tow to a Ford Retailer because the Service Tech at a Lincoln Retailer informed me they were backed up having 10 vehicles waiting to replace failed Ecoboost engines all with coolant leaks most likely I would need the same. After the $400 diagnostics I was told that I needed a new engine! Unlike the Lincoln Tech, Fords would not discuss anything about all the news, recalls or TSBs on Failed Ecoboost Engines. My Powertrain Warranty had recently expired well under mileage I would be responsible to pay. My MKCs decline happened suddenly and rapidly went downhill. First I noticed it was loud at start up which was odd and was running very rough. I checked underside and the rear to see if something was hanging and noticed a bluish gray smoke come out of exhaust for under a minute then then all symptoms cleared. Next for the 1st time a Check Engine Light came on which indicated a Misfire in Cylinder 4. Finally I had no heat in the cabin yet the engine was starting to overheat this time the Check Engine Light was blinking rapidly while driving at night in the freezing cold with my young daughter with me. It was very dangerous with supercold tempuratures being Winter in the NorthEast with icy roads. I started to smell a chemical burning odor. I have never experienced an overheating engine before in my life. I was scared and panicking not wanting to risk my engine blowing up or catching fire especially with my young child. I had no choice but to put all the windows down and pull over on the side of the road which had no sidewalks. The hood was very hot to touch. Next I am under the hood with a flashlight to check the fluids when I first became aware of the Coolant Reservoir was near empty, which explained the lack of heat and overheating. I owe $10k and it will cost $10k to replace Fords FAULTY Engine.
