Engine Cooling System Problems of Lincoln MKC

My 2016 Lincoln Mkc with a 2. 0l ecoboost engine experienced coolant intrusion into cylinder 3, leading to engine misfire and check engine light to turn on. The dealership confirmed the issue for $176. 55 and recommended a full long block engine replacement, estimated at over $11,000. This failure occurred at 98,000 miles. Two weeks before this, the check engine light illuminated and we took it to a repair shop where we paid $628 to repair the purge valve and fuel pressure sensor, while it was most likely this coolant intrusion both times! Ford and Lincoln (including concierge) have refused any assistance in this matter. The local dealership has also said that they cannot help us with any of the cost. I've found this to be a very well documented problem/engine design failure, including htsa id number: 10162062 manufacturer communication number: TSB 19-2172 entitled components: engine and engine cooling the TSB acknowledges a design-related coolant leak into the engine cylinders that can cause white smoke, misfire, rough running, and warning lights. Ford’s recommended repair is to replace the long block assembly. In addition, this appears to be the exact issue described in Ford TSB 19-2346, which covers 2017–2019 model year vehicles with the 2. 0l ecoboost engine, including the Lincoln Mkc and mkz. I believe this is a widespread design defect and request NHTSA’s investigation to ensure proper manufacturer accountability. I am so thankful that this car does not belong to one of my daughters as it poses a severe safety hazard on the road and it is going to be a huge financial setback that we may not recover from.
