My nearly new 2015 Transit Connect XLT LWB - this was less than 12 hours after buying the vehicle.
Not sure why it melted, but I need to get another one ASAP, and hopefully this won't happen again.
It ended up melting the upper piece above the taillight also....
trying to attach a picture here of what this looks like, but no success...
