There is a coolant leak going into the cylinder 3 causing misfire and overheating and engine shutoff Car shut down and locked up on the highway and I had to coast to the shoulder and get it towed. The ford dealer said it needs an engine replacement specifically a long block assembly estimated at 10k. It was inspected by the ford dealership. there was a code p0303 saying misfire so I got all the spark plugs replaced and when i was driving home from work the car locked up and said overheating and had to coast off the highway. I have all the reports and documents from the ford dealership showing the coolant intrusion into the cylinder. this is a design flaw with this engine and has a TSB already on it but not recall. it's been going on since 2019 but they still produced these engines and make the customer pay for their flaws.

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 (FOIA), 5 U.S.C. 552(B)(6)

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.

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.
