While driving the car in commuter traffic on Route 22 Highway the car transmission stopped working and car bucked and then stopped. Upon getting out of the lane of traffic there was a large amount of transmission fluid on the ground. Car had to be towed as it would not move. Danger was the car stopping on the highway in busy traffic. Upon inspection by car dealer they found it had a broken transmission cooler line .

Approximately 2 weeks ago, my 2017 Lincoln MKZ Reserve began sputtering/hesitating during acceleration. On 03/31/2025, I took it to the Heiser Ford-Lincoln in Glendale, WI for service and the diagnosis was I needed to replace my “engine long block” because of engine coolant leaking into the engine cylinders. I was given at an estimated cost of $8,000. I researched and found Technical Service Bulletin 22-2229 listing this issue as a not-so-uncommon problem with Ford’s 2.0 Liter engines. I am highly concerned that this could cause the engine to seize while driving with coolant compromising the viscosity of the engine oil. I firmly believe this should be elevated to a Recall status as this engine is used in several 2017 through 2019 Ford and Lincoln car models - and the occurrence has been frequent enough to have a TSB created.

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 Vehicle was at 58,735 miles but warranty was out of date.
