Autocar is recalling certain model year 2008-2012 Xpeditor heavy-duty class 8 vehicles, manufactured from December 17, 2007, through July 10, 2012 and equipped with a right-hand (passenger-side) Bostrom air-ride seat. The seatbelt and tether intermediate connection point (ICP) located on the seat bracket may interfere with the seatbelt retractor mechanism as the seat is pneumatically adjusted for height. Over time, the interference may cause the retractor mechanism cover to crack, allowing the retractor spring to become loose and inoperable. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard No. 208, “Occupant Crash Protection.”
