Vehicles Affected: Approximately 410,000 model-year 2015-19 Ford F-150 pickup trucks built at the Dearborn Truck Plant in Michigan between March 18, 2014, and Nov. 17, 2018, and the Kansas City Assembly Plant in Missouri between Aug. 21, 2014, and Nov. 17, 2018; model-year 2017-19 Ford Super Duty trucks built at the Ohio Assembly Plant between Feb. 5, 2016, and Nov. 17, 2018, and the Kentucky Truck Plant between Oct. 8, 2015, and Nov. 17, 2018; all affected vehicles are equipped with engine block heaters
The Problem: Water and contaminants can intrude into the block heater cable's splice connector resulting in corrosion and damage to the cable over time. Prolonged corrosion in the connector can cause a short, make the engine block heater inoperable and/or trip household breakers or GFCI-equipped outlets while the vehicle is parked and the block heater plugged in. The risk to safety only exists while the vehicle is parked and the block heater cable is plugged into an electrical outlet.
The Fix: Dealers will inspect the engine block heater cable and replace it if it is damaged or corroded. If there are no signs of damage or corrosion, dealers will apply dielectric grease to keep water out of the splice connector and reconnect.
What Owners Should Do: Ford did not immediately announce an owner-notification schedule. Owners can call the manufacturer at 866-436-7332, the National Highway Traffic Safety Administration's vehicle-safety hotline at 888-327-4236 or visit its website to check their vehicle identification number and learn more. If a replacement cable is required but unavailable at your local dealership, customers will receive an information sheet and will be notified via mail for a follow-up appointment once the parts become available.
