Coolant intrusion into the cylinder and requires a replacement of the long block engine assembly which was a known issue by Ford/Lincoln with no recalls issued. The problem has been confirmed by authorized Ford/Lincoln dealer and independent service center. Warning lights illuminated when car was brought to dealer for inspection. It poses significant safety risk that actively endanger me and passengers while driving due to sudden loss of power, engine stalling, engine fire, loss of braking and steering assistance.
NHTSA complaint #11758708 — an unverified report by a vehicle owner.
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

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.

Car started shaking roughly when started, check engine light came on for cylinder misfire. Known engine problem where coolant leaks in to the engine block due to a known defect from Ford for these 2.0L engines. There is a TSB 22-2229 ([XXX]) already issued for this. Dealer inspected and confirmed the problem. Now the entire engine long block needs to be replaced resulting in $10,000 repair.

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.

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.

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.

There is coolant intrusion into the cyl. It is a known concern and many complaints on line. Lincoln refuses to assist in the engine repair or replacement. Going down the road the engine misses and looses power causing difficulty controlling vehicle causing unsafe conditions for all traffic.
NHTSA complaint #11750623 — an unverified report by a vehicle owner.
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.

I am thoroughly disappointed and overwhelmed. My vehicle has 122,000 miles on it. Yes that may be considered many for some but this vehicle has been taken care of extensively and all routine scheduled maintenance has been performed. I purchased from Preston Ford in Pittsville, MD and the vehicle had 48000 miles as a used vehicle. I have had many minor issues,(fuel flap), A/C issues and 2 recalls for back up camera and the vehicle had a recall stating the car may catch on fire so don't park near other structures. Supposedly both recalls were taken care of by the seller of my vehicle. Now I am told I need a new engine, my engine light came on and I thought it was the purge valve assembly. Now this is my first Ford product so I am sad to report this. I still owe on this car and was told a new engine would cost about 10,000. I use the car for work and is my livelihood. I do not know who to contact and would hate to see someone else with this same experience. I feel if you take care of your vehicle it should get more than 122,000 miles.
