Ford backs more than 874,000 F-Series pickups in the US and Canada with engine block heaters because they can catch fire.
The recall covers certain F-150 models of the 2015-2019 model years from 2017 to 2019 F-250, 350, 450 and 550.
The company says in Friday on the website of the US National Highway Traffic Safety Administration has published documents that water and contaminants can enter the heating cable and cause corrosion. This can lead to electrical short circuits and possible fires. Engine block heaters warm up the engines so they can start and warm up faster in extremely cold temperatures.
The company states that there is a risk of fire only if the block heater cable is connected to a power outlet.
Ford has received three reports of fires in Canada, but not a single property damage was reported in the US, but there were no reports of injuries, Ford said in a statement.
Dealers inspect and seal the cable or replace the cable heaters if necessary. The recall is expected to begin on January 7 in the US.
F Series pickups are the best selling vehicle in the United States.
