Seat Belt Retractor Pretensioner Inadvertent Deployment
On November 22, 2023, the Oï¬ce of Defects Investigation (ODI) opened Preliminary Evaluation (PE) PE23021 to investigate complaints of front seat belt retractor pretensioner inadvertent deployment in model year (MY) 2019 Ford Expedition vehicles manufactured by Ford Motor Company. Some complaints alleged hearing a loud, explosion-like sound immediately followed by the seat belt tightening around the occupantâs torso area. The complaints did not state that a crash occurred that may have resulted in the deployment of the pretensioner system, suggesting that this deployment was inadvertent or otherwise unwarranted. On February 9, 2024, Ford issued safety recall 24V-099, recalling certain MY 2018-2020 Ford Expedition and Lincoln Navigator vehicles equipped with driver and front passenger seat belt retractor pretensioners built between October 1, 2018, and June 30, 2019. Ford described the defect as a seat belt retractor pretensioner assembly that may develop corroded squib pins, resulting in high resistance or an open circuit, which could result in an inadvertent deployment of a pretensioner and an increased risk of injury due to the loss of the pretensionerâs protection and a sea
Seat Belt Pretensioner Inadvertent Deployment
On November 22, 2023, the Office of Defects Investigation (ODI) opened PE23-021 to investigate instances of seat belt pretensioner inadvertent deployment in model year (MY) 2019 Ford Expedition vehicles manufactured by Ford Motor Company. Some complaints allege hearing a loud, explosion-like sound immediately followed by the seatbelt tightening around the occupantâs torso area. The complaints do not allege a crash occurred that may have resulted in the deployment of the pretensioner system. The investigation revealed certain seatbelt pretensioners may develop corroded squib pins where the bridge wire (heating element of pyro-technic device) is welded. 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 inadverte
