Ford will be contacting a small number of 2020 Ford F-150 owners because of a problem with the electrical system in their trucks. According to the safety report filed with the NHTSA, the affected vehicles were built at their Kansas City assembly plant June 30, 2020 and July 1, 2020.
These trucks may have been built with a positive power supply cable nut that does not meet design specifications. These nuts do not have the correct torque characteristics or conductive coating needed at the power supply attachment to the starter motor. This could increase the amount of heat generated during starting and could create an electrical arch that could start a fire. Drivers will be alerted of a problem through grinding noises when starting or restarting during a stop-start event, or the engine may not start at all.
Owners receiving notices will be asked to return to their dealers to have the starter motor B+ power supply attachment nut replaced with the correct part. Ford’s number for this recall is 20S40 and the NHTSA campaign number is 20V-467.
