NHTSA Complaint #11651649 — 2017 LINCOLN MKZ

I have purchased a used 2017 Lincoln MKZ Reserve 2.0l in August of 2023 that started losing coolant and smoking from exhaust. Upon further investigation the coolant was noticed in the cylinder 2 through the spark plug opening. I had changed the head gasket and noticed the slotted coolant journals between the cylinders which was clear this was where the coolant was leaking from. After replacing the cylinder head gasket it run fine for about another month before starting to have same issues of losing coolant and smoking from exhaust, coolant was observed in cylinders 2 and 3. Ford recommended replacing the engine to the new design engine that eliminated the slots, this would be at Customer cost. Engine cost was $2,618.67 in March of 2024 just to purchase the engine, i replaced the engine myself. Vehicle was at 58,735 miles but warranty was out of date.
