Wow, is no one from Ford KTP PVT monitoring this forum?!
Has anyone affected requested the dealer to do a TSB search or had an audience with a Ford Motor Co. Service representative? This string is all the proof needed to demonstrate this is a systemic, production date bounded issue.
This is clearly build/running change related. After closely reviewing my 2020 it would seem mechanically and dimensionally inconceiveable for this to happen to it, with or without ice. Some of these vehicles need to be reviewed, maybe some bought back, torn down and understood, unless this problem is already understood. Either way some sort of campaign needs to be undertaken immediately to prevent/address this issue. This would be a good forum to publicize that campaign. Simply handing it off to a bodyshop is not going to work. This is a fit and function issue.
Many years ago, this would have been my responsibility at Ford. Once there were 2 known vehicles with such a condition....such a campaign would have been developed and approved within 24 hrs....just saying.
