This is all I could find:
"Nearly 200,000 Taurus sedans from the 2010 to 2014 model year are being recalled for corrosion issues. In areas where road salt is used, corrosion can cause the license plate lamp to short circuit, overheat and possibly cause a fire. Ford knows of 18 fires that started because of this issue, one of which a customer put out by hand, suffering an injury in the process."
