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 Vehicle was at 58,735 miles but warranty was out of date.

I have a 2017 Lincoln MKZ; coolant is leaking into the engine block; have to replace the entire engine. Car has 82K miles on it. Bad thing is that my daughter's Ford Fusion (2017) had the same problem just two months. I had to replace the engine in her car. It is clear that Ford/Lincoln has this problem, Stories on the internet. Ford did issue a recall but just for the 1.5 Liter car; both of mine were 2.0 liter. These engines should be recalled - should not be happening. Daughters car just has 45K miles on it.

On Jan. 10, 2025 all the brake fluid leaked out of my MKZ. Fortunately, this occurred a few miles from my home and was able to get the car into the drive.

On 1/13/25 I had the car towed to a local Ford Dealer and was informed that the brake lines to both rear wheels were indeed severely rusted thru and had to be replaced.
