Extended corrosion and a partial separation of the weld may cause a high resistance or an open circuit condition to occur, potentially resulting in pretensioner inadvertent deployment. Inadvertent pretensioner deployment will result in the seatbelt being locked in position, no longer able to extend or retract as designed, which may result in injury in the event of a crash. 11 minor injuries were reported due this failure. Most injuries were bruising to the torso area caused by the rapid tightening of the seatbelt during an inadvertent deployment. On February 9, 2024, Ford filed recall 24V099 for certain MY 2018-2020 Ford Expedition and Lincoln Navigator vehicles with production dates between October 1, 2018, and June 30, 2019.
