The driver-side seat belt retractor on my 2015 Ford Mustang GT Premium has failed. The seat belt retracts back into the retractor housing when released; however, it does not lock when pulled sharply and continues to extend freely. I confirmed this by repeatedly performing a rapid pull test while seated in the vehicle. The failure affects the seat belt restraint system because the belt does not appear to engage its locking mechanism. This could increase the risk of injury in a crash because the seat belt may not properly restrain the occupant during sudden deceleration or impact. The issue was inspected and confirmed by a Ford dealership service department. The dealer diagnosed the driver-side seat belt retractor as failed and recommended replacement of the retractor assembly. The dealer provided an estimated repair cost of approximately $550 plus tax. The vehicle was inspected by Smith Ford in Conway, Arkansas. The vehicle was also inspected for a separate seat belt recall, and the recall inspection passed. The dealer advised that the failed retractor was not related to the recall and would require customer-paid repair. There were no warning lights, messages, or airbag system warnings present when the failure was discovered. The primary symptom was that the seat belt would retract normally but would not lock during a rapid pull test. The exact date the failure first occurred is unknown, but the condition was identified during normal vehicle operation and later confirmed by the dealership.

Seat belts
- What is wrong
- 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."
- Risk
- If the tension sensor misclassifies the front passenger, improper passenger air bag deployment may occur, increasing the risk of occupant injury in the event of a vehicle crash.
- Remedy
- Ford has notified owners, and dealers will replace the passenger safety belt buckle, free of charge. The recall began on October 28, 2014. Owners may contact Ford customer service at 1‑866‑436‑7332. Ford's number for this recall is 14C08.

Seat belts: front: anchorage
- What is wrong
- Vehicle description: passenger vehicles. The seat belt retractor may have a pin shaft in the switchable elr/alr mechanism that is incorrectly formed. In some circumstances, the switching mechanism could become nonfunctional, preventing the seat belt webbing from being extracted from the retractor. It is also possible that malfunction of the mechanism could prevent the belt from being switched into the alr mode. The elr mechanism is not affected by this condition.
- Risk
- If the mechanism malfunctions and does not allow the webbing to be extracted, the lap and shoulder belt could not be worn by a vehicle occupant. In the event that the mechanism does not allow the alr mode to be engaged, the operator may be unable to properly install a child seat in that seating position.
- Remedy
- Dealers will inspect the lap and shoulder belt assemblies. Assemblies with julian date codes of 200 through 223 are suspect and will be replaced.
