What 182 owners told NHTSA about the 2017 Lincoln Mkc

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Related to previous recall [XXX] I had the recall repair done. But my car with only 86,744 miles now has coolant in cylinder 3 and it's misfiring so badly the car shouldn't/can't be driven. Dealership says the entire engine needs to be replaced. I have NEVER had a car this low of mileage that an entire engine needed replacement. This is a design flaw in the 2.0 ecoboost and I now have a probably 20,000 or whatever it may have been worth when it ran... Paperweight. It's just sputtering and spitting out loads of smoke as described in original TSB. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My engine kept misfiring upon starting and not accelerating while I was driving it. A coolant leak into the cylinder caused the engine to malfunction. I had to replace the entire engine block which cost over $7,000.00. The Ford repairman & service center told me that Ford had issued a service bulletin regarding this issue but then refused to pay for the engine damage. I only have 70K miles on the Lincoln.
