2019 Lincoln MKC Complaints

ENGINE — Filed 06/05/2026

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.
