I just went through this nightmare with Ford ! My 2018 Ford Edge Titanium with the 2.0L ecoboost engine was completely problem free until 72,000 miles. Then suddenly i noticed that the coolant level was gradually dropping . At first I added coolant every 3-5 days but this began to increase significantly. Also I began to get misfire trouble coded ( P301) for cylinder number one followed by white smoke out the exhaust just after startup. I immediately educated myself on the diagnosis from several credible you tube content providers on the subject. The most current TSB of FORD indicates that the engine block is compremised ( due to poor engineering of the coolant passages ) and that only a complete long block replacement is the solution . Depending on your dealer , this overall cost ranges from $6500 - $7700 !!! After multiple discussions with FORD customer service they advised me that they could offer NO PARTICIPATION in resolving this problem and implementing the TSB ( NO FINANCIAL SUPPORT) and that the cost of a replacement engine was 100% my problem !! There are several class action lawsuits in process regarding the coolant intrusion issues of the 1.5L ecoboost engines and now there are two ( one in Delaware and one in California ) regarding the 2.0 L ecoboost. With zero alternatives I had my engine replaced at my cost. Trust me when I tell you that I will be participating in any legal action against FORD on this subject. They basically had an engineering screw-up , that 'never' showed up in their engine testing and now are just hoping the luckless customers disappear . That wont be happening in my case.
