Yep just cheap plastics from secondary source. The first time it happened I only had the vehicle a few months and it happened in the cold months as well.
Nope no direct heat sits in a garage that's open so it doesn't get hot in there. And like everyone else I go to the car wash that other broncos use and there's isn't doing it
My plastics are doing it too but every where and it happens in the cold. I've had them replaced once and ford apparently used the same batch of shit plastics andits doing it again but worse than before.
