A rear suspension component called a toe link may fracture and result in the vehicle suspension becoming unstable. This could result in loss of vehicle control and lead to an accident.
The tires may have been damaged on the inside sidewalls during vehicle assembly. This could result in tire failure, and subsequent loss of vehicle control.
The driver's frontal air bag may not deploy full in a crash, resulting in increased risk of occupant injury.
The engine block heaters equipped on affected vehicles may overheat, resulting in a possible fire risk.
The passenger seat has a mechanism that determines if an occupant in the seat is an adult that should have protection offered by the passenger frontal air bag in the event of an accident. This mechanism also turns off the air bag and prevents its deployment in the event it detects a child in the seat. The system may malfunction and shut down the passenger side air bag preventing deployment when the seat massage feature is active, even with an adult in the seat. This increases risk of injury.
The inflator that deploys the driver's frontal air bag in the event of an accident may rupture and spray metal fragments onto vehicle occupants. This can increase risk of serious injury or death.
The headlights may fail to operate because of a failure of the lighting control module. This can cause reduced visibility and increased risk of an accident.
The front seat belts may not be properly assembled and could fail to restrain occupants in an accident. This would result in increased risk of injury.
For Roush modified Mustang's, the rear caliper guide pins may not be secured properly, which can result in loss of proper braking from the rear wheels. This can increase the risk of a crash.
The fuel delivery module may crack, causing fuel to leak. This can result in a fire hazard and fuel odor.
