2017 LINCOLN MKC Forward Collision Avoidance Adaptive Cruise Control Problems

I own a 2017 Lincoln MKC 2.0L EcoBoost that suffered a complete engine failure caused by coolant intrusion into the combustion chambers. The vehicle began to misfire, emit thick white smoke, lose power, and quickly became almost undriveable. Technical Service Bulletin (TSB) 19-2346 (June 2019), which describes coolant entering cylinders due to a flaw in the cylinder head/block design. This failure is not the result of neglect or normal wear and tear — my vehicle has been maintained according to manufacturer recommendations. Despite this, the engine requires complete replacement at a cost of approximately $9,500. The failure occurred well before what should be the normal service life of an engine, and it matches the same defect pattern reported by many other Lincoln and Ford owners with the 2.0L EcoBoost engine in multiple model years. The coolant intrusion defect creates a serious safety hazard because it can cause sudden, unpredictable loss...

This safety feature for braking, collision, warning. and adaptive cruise control fails on the majority of MKCs and simple google search shows the frequency in online forums of this system consistently failing.
