Hello, everyone! I have also had this same issue with my 2019 TC. I purchased my van in August of 2019 and this issue began almost immediately. I had brought it in so many times that my local dealership just gave me a new van in October of 2019.
This problem has occurred again in the new van, and I brought it in again today. The service staff notified me today that Ford has recently issued a TSB regarding this problem and that a fix should be available by next week. I have a service appointment the week after next. Hopefully, this will fix the issue.
Have y'all found any solutions yet?
