I have nearly the same problem. Bought a used vehicle from a reputable dealer. Didn’t even get the license plates on it yet and got a CEL. Did the same thing, changed plugs and coil packs. Still have the issue. With some research, found the technical bulletin, did the pressure test, and it failed. Used a borescope and can clearly see water in the #2 cylinder. Unfortunately, it took just a few more miles than the 1000 mile warranty to see and determine the root cause of the issue. Car is a 2017, and only had 37k miles on it. Not sure what the next steps will be. Does anyone have current info on the class action lawsuit? Anyone have luck getting Ford to address the issue? Have read some comments about taking Ford to small claims court, but haven’t seen any feedback on the outcomes. I have a feeling I may be eating this one. Can’t trust anyone these days
