Ford Motor Company (Ford) is recalling certain model year 2015 Ford Mustang vehicles manufactured August 18, 2014, to October 2, 2014. In the affected vehicles, the passenger safety belt tension sensor may misclassify the size of the front passenger seat occupant. This could cause a child size occupant to be classified as an adult and an adult passenger to be classified as a child passenger. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 208, “Occupant Crash Protection.”
