Intermittent P0302 CEL codes fired for Cylinder 2 misfire, over last month. Replaced plugs and coil, Code cleared. Same CEL indicator and code fired again. Symptoms are Rough start up, coolant needing replenishment, took into dealer, coolant intrusion into cylinder 2 requiring engine replacement. This is obviously not an isolated incident with this 2.3L Ecoboost engine, what was know by Ford to flawed during the 2017-2020 period. Two months after purchase of my 2017 MKC, had to have the short block replaced, under warranty, but the head was already warped and they replaced the head gasket on a warped block knowing it was only a matter of time that it started leaking. Now out of the range of that warranty and with looming $8k expense, not happy.

Recently, my 2017 Lincoln MKC has exhibited concerning symptoms that warrant further investigation. Upon starting the engine, I have noticed a slight but noticeable tremor. Though this subsides once the vehicle is in motion, a persistent roughness persists during gear changes, accompanied by the emission of white exhaust from the tailpipe. The situation escalated further with the illumination of the "Check Engine" light. Consequently, I sought professional diagnosis from a certified mechanic. Unfortunately, the diagnosis revealed a significant issue: a broken head gasket leaking into the engine. Remedying this requires a complete engine rebuild. Disturbingly, the mechanic indicated that this problem is not entirely uncommon in Lincolns, and even a full rebuild may not guarantee a permanent solution. I have come across information regarding a class action lawsuit entitled "Reed et al v. Ford Motor Company 2:2021cv00417, " which I intend to contact to report my experience and contribute to their investigation. Additionally, I have contacted the original dealership where I purchased the vehicle and am actively exploring all available options to address this concern.
