2019 Lincoln Mkc Engine Problems

I am filing an urgent safety complaint regarding a severe Ford/Lincoln EcoBoost engine defect, fraudulent recall reporting, and the illegal refusal of repair on my vehicle, which has only around 20,000 miles. Since this vehicle is under an active safety recall, the manufacturer and dealership have a strict legal obligation to perform the recall repair at no cost to the consumer.My vehicle recently experienced a major engine failure with the Check Engine Light illuminated The authorized dealership diagnosed the issue as an inherent EcoBoost engine defect, specifically confirming a Cylinder #1 Misfire caused by Coolant Intrusion into the engine cylinders. They stated that the engine is severely damaged and provided a repair estimate of $12,000 for a complete Long Block Engine Replacement.However, they are completely refusing to cover this repair, telling me that they cannot help me and that I must pay out of pocket to fix it myself. To evade their legal safety obligations, the manufacturer sent an official letter falsely claiming that the recall service was already successfully completed at Norm Reeves Lincoln on April 24, 2024. This is a complete lie. I have NEVER received, authorized, or brought my vehicle in for this recall service.They have fraudulently marked this safety recall as completed in their system to strip away my consumer rights and leave me with a dangerous vehicle and a $12,000 bill. Operating a vehicle with coolant intrusion poses an immediate risk of sudden engine stalling, catastrophic failure, or fire on the highway. I formally request NHTSA to investigate this fraudulent recall reporting and unlawful refusal of repair, and compel Ford/Lincoln to perform the actual safety recall and long block engine replacement immediately at no cost as required by federal law.

The vehicle needs a complete engine replacement due to a coolant intrusion issue. The safety of myself and my family are of my utmost concern. Overheating of the system can cause sudden engine stalling, catastrophic power loss at highway speeds, a risk of collision, and toxic vapor exposure inside the vehicle. Furthermore, A leaking heater core vents sweet-smelling but toxic antifreeze vapors into the passenger compartment and prolonged breathing of heated glycol fumes can trigger dizziness, headaches, and nausea for the driver. All of which I have recently suffered from. I have taken the car back to the original dealership and was advised that I would need a new engine. The engine light came on and the coolant started spiking into the red which led me to take the car in for diagnostic testing.

To NHTSA: I am filing this complaint about a dangerous stall/overheat defect in my 2019 Lincoln MKC, VIN [XXX], currently at 79,820 miles. This vehicle was built 2018-10, before Ford's engine redesign, and it is now undrivable due to coolant intrusion into the engine, a known and documented defect covered under Ford TSB 22-2229 for the 2.0L EcoBoost engine. What happened: the car overheated on me at Church's Chicken. I came out with coolant to top it off, and cautiously drove it to Dr Underhood Repair Shop. They ran the codes and quoted a full engine replacement, but couldn't source an engine, so they sent me to the dealership. I paid them and limped the car across town to Randall Ford. Randall Ford confirmed the failure matched the TSB. I paid them too, and the car overheated again within 500 feet of leaving their lot. I had to park it at a strip mall and have it towed to our warehouse, where it sits undriveable today. Randall Ford's diagnosis (repair order XXX, dated XXX) is coolant leaking into the engine, requiring a new engine, quoted at $16,735.60. The codes pulled were P0217, P0303, P0316, P0420, and P06E9 - overheat, misfire, misfire, catalyst efficiency, and turbocharger coolant/fluid, all consistent with the coolant intrusion pattern described in TSB 22-2229. I confirmed rough running, and the car overheating with no visible external leak, which matches the pattern in Ford's own bulletin. I am aware Ford issued CSP 21N12 to extend coverage for coolant intrusion on the 1.5L EcoBoost engine, but no equivalent program or recall exists for the 2.0L EcoBoost engine in my Lincoln MKC, despite the same defect and the same TSB language applying. There has been no recall issued for this problem on my vehicle at all, even though Ford is well aware of the defect. I also want to note that this is not an isolated issue with this vehicle - I have separately experienced the documented purge-valve/fuel-system defect on this same car, which suggest INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FO

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.

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.

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.
