"If the multi-contour front passenger seat massage function is turned on and an adult is in that seat, the occupant classification system may incorrectly classify the adult as a child — suppressing the front passenger airbag and increasing the risk of injury in a crash," Ford said in a statement.
There are no accidents or injuries linked to the recall.
The affected F-150s were built at the Dearborn Truck plant from April 27, 2015 through November 22, 2015.
No information about the recall has been posted on the website of the National Highway Traffic Safety Administration, which oversees vehicle safety in the U.S.
Edmunds says: This recall begins soon, so owners should be ready to make a service appointment at a Ford dealership in early March.
