NHTSA complaint #11763992 — an unverified report by a vehicle owner.

ENGINE

I own a 2018 Lincoln MKC equipped with the 2.0L EcoBoost engine. The vehicle currently has approximately 72,326 miles. The check-engine light initially illuminated and an OBD scan produced code P0303, indicating a misfire in Cylinder 3. No other diagnostic codes were reported. Following mechanical evaluation, all four spark plugs and ignition coils were replaced. Approximately 145 miles later, the check-engine light returned with the same P0303 code. The code was cleared to confirm recurrence, and approximately 111 miles later the check-engine light illuminated again. I subsequently took the vehicle to a Ford/Lincoln dealership for further diagnosis. The dealership determined that coolant is leaking into Cylinder 3 and advised that the required repair is replacement of the engine/long-block assembly, at an estimated cost of approximately $8,900. I have since learned that Ford issued Technical Service Bulletin 19-2346 addressing certain 2017–2019 Lincoln MKC vehicles equipped with the 2.0L EcoBoost engine that may exhibit coolant intrusion into the cylinders, an illuminated malfunction indicator lamp, and misfire diagnostic codes including P0303. The prescribed repair under the bulletin may require replacement of the long-block engine assembly. A search of NHTSA's recall database using my VIN does not presently identify my vehicle as subject to a safety recall for this coolant-intrusion condition. I am submitting this complaint so that NHTSA has a record of another 2018 Lincoln MKC 2.0L EcoBoost experiencing a dealer-confirmed coolant-intrusion failure consistent with Ford's published technical guidance. I am particularly concerned about whether this failure mode has safety implications and whether the population of potentially affected vehicles has been adequately identified. The vehicle had not exhibited significant drivability problems, rough cold starts, or other obvious warning symptoms before the recurring P0303 check-engine indication.

ENGINE

My engine failed. At the time I did not know this. I was driving to work, and although I knew I was not out of gas according to the gas gauge, I thought maybe something was wrong with the gauge when my Lincoln began to putter like when you are running out of gas. I was approaching a stop light in the left turn lane when the car died. Which could have caused a multi car pileup considering the intersection in my town I was at. I got the car to start again but it smelt terrible and started smoking from the exhaust. A white smoke. I was not far from work at all so I made it there and had a mobile mechanic come to look at it. Upon inspecting it, he found oil build up in my spark plugs. When he tested the compression there was no compression at all in cylinder 4. There were no prior indicators such as check engine lights or any other lights. I had just financed this vehicle not even 6 months prior so not only did being stuck at a busy intersection full of anxiety and praying no one hit me, it has caused tremendous financial hardship as I have still been faithfully making my loan payments and paying full coverage on the vehicle. And has left my husband and I without a vehicle. He works 50 minutes from where we live and I work 20mins from where we live and in opposite directions. I since found out there are class action lawsuits for this year,make,model, and engine. I contacted the only shop in my town which is a Ford Lincoln dealership about the issues and was informed that most likely the cost of repairs/replacement would be $10,000 and to contact Ford corporate. Which I did and was denied any sort of assistance with cost when they should have to cover the whole thing as it is a major safety issue. Let alone the financial burden their defective engines are placing on people such as myself. This could have caused a major car accident potentially resulting in severe injuries to myself and others. I did not know until now I could report these types of safety issues.

ENGINE

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

ENGINE AND ENGINE COOLING

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.

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.

ENGINE

I am experiencing a coolant-intrusion problem with my 2018 Lincoln MKC, equipped with a 2.0L EcoBoost engine. The vehicle has only 63,900 miles. •The check-engine light repeatedly came on and went off over a two-week period. •A Lincoln dealer performed a diagnostic evaluation and identified the same problem reported in other Ford and Lincoln vehicles with this engine. •An independent automotive service provider confirmed the diagnosis and advised me that Ford had issued a service bulletin addressing this exact issue. •Both assessments indicated that the engine needs to be replaced. When I asked the dealer what could happen if I did not replace the engine, I was warned of serious safety risks, including a possible fire or complete engine failure. This is not a routine wear-and-tear issue; it appears to be a known design defect. The problem has reportedly led to class-action lawsuits and has left many vehicle owners facing significant repair costs without financial assistance. Ford/Lincoln has stated that it will not cover the cost of replacing my engine because the vehicle is no longer under warranty.

ENGINE

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.

ENGINE

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.
