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
