FORD issued a recall on the F150, and FLEX models

On certain vehicles, a defect in the manually-adjustable seat tracks may cause the occupant classification system to incorrectly register the weight of the seat occupant. This could affect or disable the airbags and other supplemental restraint systems, and could increase the risk of injury to the seat occupant in a crash that warrants airbag deployment and/or other supplemental restraint system function. Correction: Dealers will adjust seat track spacing and recalibrate the occupant classification system.
