We have classified the 2 complaints from 2018 Ford F-150 about STRUCTURE into the following categories.
Doors will no shut and latch in cold temperatures. very unsafe. has happened multiple days.
In cold weather the door latches freeze causing the doors to remain unlatched. this caused my rear doors to fly open when i went around a corner. there was a recall but it doesn't cover the 2018 model year. my truck was made in oct 2017, and i took delivery in mid dec 2017. the dealer will inspect, but as yet ford doesn't appear to have a fix for the issue.
