Ford has recalled over 874,000 F-Series trucks with engine block heaters that can start a fire when plugged into the wall. The automaker believes a low and unshielded mounting position is allowing road salt to corrode the heater cable’s splice connector, causing at least three known fires.
Block heaters are made for cold climates. Road salt is too. I’m not sure how those blockheads forgot to shield those cables in the first place.
