2019 Lincoln Mkc Engine Problems

1. What component or system failed or malfunctioned, and is it available for inspection upon request? Answer: Engine / Powertrain (Engine Block & Cooling System). The vehicle suffered an internal engine failure caused by coolant intrusion into Cylinder #4, requiring a full engine long block replacement per Ford Technical Service Bulletin (TSB) 22-2229. The vehicle and component are available for inspection upon request. ​2. How was your safety or the safety of others put at risk? Answer: The engine suffered a sudden and complete loss of power without warning in the middle of active, moving traffic, leaving the vehicle dead in a live travel lane. Because the engine stalled abruptly due to coolant flooding the cylinder, the vehicle became an immediate, stationary obstacle in harm's way, creating an extreme risk of a high-speed rear-end collision or chain-reaction pileup that easily could have resulted in severe injury or a fatality for myself and other motorists. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Answer: Yes. The problem was confirmed by a certified technician who pulled active diagnostic trouble codes P0304 and P0316. The technician performed a borescope inspection through spark plug #4 and visually verified coolant intrusion inside Cylinder 4. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Answer: Inspected and diagnosed by a servicing dealer/technician who generated an official repair estimate (#9,496.97) confirming the defect and recommending engine replacement per Ford TSB 22-2229. (Note: Mention if inspected by insurance/police, otherwise leave as dealership/facility only). 5. Were there any warning lamps, messages? Answer: The Check Engine Light (CEL) illuminated immediately before or during the engine shutdown. The diagnostic codes (P0316 and P0304) indicate startup misfires caused by coolant accumulating in the cylinder while parked.

Incident

Aug 1, 2026

Component: Engine (2.0L EcoBoost) — coolant intrusion into cylinders What failed: The engine in my 2019 Lincoln MKC (2.0L EcoBoost, approximately 83,000 miles) failed due to internal coolant intrusion into the cylinders. This is a known defect in this engine, documented by the manufacturer in TSB 22-2229 (superseding TSB 19-2346), which acknowledges coolant leaking into the cylinders on 2.0L EcoBoost vehicles and specifies complete long block engine replacement as the only repair. My vehicle and the failed engine are available for inspection upon request. The car/engine is currently at the [XXX] Ford in Draper, UT. Safety risk: Coolant intrusion causes engine misfires and can cause sudden loss of engine power while driving, hydro-locking of the engine, and — per the manufacturer's own bulletins and pending litigation — overheating, cracked cylinder heads, and engine fires. The check engine light began flashing while I was on the highway. I am also a dialysis patient awaiting a kidney transplant, and a sudden engine failure or stall while driving to medical treatment poses a serious safety risk. Confirmed by a service center: Yes. On or about XXX, [XXX], a franchised Lincoln dealership, performed a borescope inspection of the engine and confirmed the failure, stating the engine must be replaced at a quoted cost of $7,897.45. I have the written diagnosis and repair estimate. Inspected by the manufacturer or others: No police or insurance inspection was involved, as this was a mechanical failure rather than a collision. Warning signs before failure: Unexplained low coolant level requiring repeated top-offs; white smoke from the exhaust, especially at cold start; check engine light, steady or flashing; rough running or misfire, often with codes P0300–P0304 or P0316; sweet coolant smell.

Incident

Apr 7, 2026

The engine on my 2019 Lincoln MKC (2.0L EcoBoost) suffered a sudden internal failure without warning shortly after the factory powertrain warranty expired. The vehicle had no prior drivability issues, no warning lights, and had been maintained on schedule. While driving, the engine began running roughly and quickly lost power. The vehicle became unsafe to operate and had to be towed. The dealership diagnosed the engine as having internal mechanical failure requiring complete engine replacement. I was told the failure was not due to maintenance and that the engine could not be repaired. The failure occurred only weeks after the 6-year/70,000-mile powertrain warranty period ended. This appears consistent with other reported EcoBoost engine failures involving internal defects such as coolant intrusion, low-tension piston rings, or block-related issues. A sudden loss of power while driving presents a safety hazard, especially in traffic or at highway speeds. I am submitting this complaint so NHTSA is aware of this engine failure pattern and the safety risk associated with unexpected engine shutdowns on these vehicles.

The head gasket has failed, leading to coolant intrusion into the number 2 cylinder. Several misfires occurred due to this. This is a known issue due to the design of the lower block, which uses a channel, thus causing a very small surface area for the head gasket between the channel and the cylinder, which accelerates wear. Spent $3,000 to fix this well-known design issue. Car at ~100k miles.

The vehicle was recalled. I took the vehicle to the dealer where it was purchased. It was serviced. The engine issue was addressed, so we thought. The repair/replacement parts did not remedy the issue, despite it being in the shop for over 6 months. The problem persists. It is overheating in a 5 minute drive. The local service department is saying there is no other remedy. They keep asking we bring it in for another diagnosis, but the problem is the same as the 47,000 other vehicles that have been recalled by this same issue. We purchased the car and have not been able to use it.

Incident

Jan 26, 2026

Purchased a 2019 Lincoln MKC from Mazda and Stokes on Ashley phosphate in North Charleston, South Carolina. I was told that the vehicle had recalls and they identify the recalls about the battery and the rear camera when I asked was there anything else wrong with the vehicle, they said no when I drove the vehicle home after a few days the engine light came on. After doing some diagnostics at the dealership, it will discovered that there was a misfire in the engine. They did a complementary repair. It took a couple of days when I received the vehicle. I took it home and after about a week, the engine light came back on for the same problem after further diagnostic come to find out that if this problem persist is because of coolant intrusion come to find out that this is common among engines that are 2.0 L Eco boost engine engines in the 2019 Lincoln MKC. I am making a complaint because I found out also that I will not get reimburse my money. Neither will they take the vehicle back. I called the Lincoln dealership and they will not do a Goodwill repair so I purchased a car about three weeks ago with them, knowing this problem and did not disclose it to me or told me about it cause this is common knowledge for this vehicle and they sold it to me and now I have payments on a broke vehicle, which I can’t afford $11,000 new engine or a long block.

Engine seizes while driving and chokes due to engine misfire. First occurence was at 34kmiles in 9/2023 and when brought for emissions check mechanic said needed new spark plugs/coil so had them replaced for $800. 3-4months later after only 1k miles check engine light goes on again and car hums/rattles like it will stall. My brother runs diagnosis and same issue and that’s when I started to do research and found that Lincoln MKC 2019 have known engine issues. As it was under warranty until dec 2024, I brought to Steven’s Ford in Milford CT and raised this engine issue and specifically asked for full repair to ensure issue is fixed. 18 months later on 11/12/2025, while driving car the engine starts to hum and rattle feel like it will seize and check engine light goes on again. Same issue from when I had repair under warranty but Lincoln dealer claims it’s a parts issue and not an engine issue. These vehicles are dangerous and can cause accident due to engine just stopping. Dealership and Lincoln refuse to provide any support.

Vehicle overheated, due to collant entering #1 cylinder. This coolant intrusion is apparently a well documented issue, from an acknowledged engine defect. (TSB 19-2346, TSB 22-2133) Ford dealership recommended an $11,000 + tax engine replacement, with no relief, as car is past its warranty. The vehicle has 58540 miles. Lincoln customer service also declined any goodwill repair. Independent Service Dealer (Craig’s Auto Repair Service 281-469-5949) first diagnosed the issue, recommended taking the vehicle to Ford Dealership (Tomball Ford).

Incident

Nov 25, 2025

My 2019 Lincoln MKC with only 52,200 miles experienced unrepairable engine damage due to an internal coolant intrusion condition that directly matches Ford TSB 22-2229. On or around Jan 1st or 2nd, a check engine warning light came on as I was driving home at night. I did not drive my car any further except to the dealership for service on 1/5/2026. The engine failure was diagnosed by the dealership on 1/6/2026. This engine failure occurred well below a reasonable engine life expectancy, and is caused by a documented design defect. The manufacturer’s refusal/delay in recalling these engines with a known design defect places drivers at risk of being stranded at any time of day or night, and drivers risk becoming a road hazard to themselves and others when experiencing complete engine failure.

2019 Lincoln MKC with 96K mileage suddenly started running rough around 30mph and I was losing power as I was entering a highway on a ramp. RPM needle was fluctuating between 2K and 3K. Immediately drove back home and towed it to Lincoln shop. They said its an issue with Coolant Intrusion into the engine compartment and would have to replace the engine block. Estimated at $11K. Extended warranty company said claim is likely to be denied as these Ecoboost 2.0L engines are notorious for these issues. It is a faulty manufacturing and there is no recall. Costing consumers thousands of dollars and also putting lives of passengers at risk.

My car misfired, then the heat wouldn't work then started to overheat. The car is 2019 MKC 2.0L engine. Only 64k miles on it. I am the original owner. Took it to the dealership and they said the coolant has back up into the engine. I read that this has been a known issue with these engines and was never notified. It is going to cost 10k to replace this engine.

Incident

Nov 21, 2025

My initial reason I took the car to the dealership, was because the vehicle would not want to start or stay running after fuel was put in. I aIso had a check engine light on. After the dealership performed diagnostics on it, they said the purge valve was bad which was the cause of it not starting. The check engine light was on because it was low on coolant. So I scheduled another appointment with Wyatt Ford in Manistee MI 49660 on Dec 1, 2025. They performed a coolant pressure test and determined that it is losing pressure after shutdown. They cannot find a leak. They removed the spark plugs, but #3 spark plug is "stuck" and they are attempting to remove it. If the spark plug breaks, they will take more of the engine apart to access it and attempt to "tap" out the threads of it. The technician (Sherman) told me that the cause of it being stuck could be due to the fact of the coolant leaking into that cylinder. Sherman was able to remove the #3 spark plug and found coolant in that #3 cylinder. They are now saying that the engine does need replaced and it is not safe to drive. The service department (Ava) gave me Ford Customer Service number to call to start a case. I called 800-392-3673 and spoke with Alex. She told me she will do some further research and call me back in about two hours. It is now 12:30 pm east coast time. After returning a call from her, she said that there are no programs at this time with Ford to assist with replacing the engine. Only if there is a recall on this is when they would be able to replace it for us.
