The hazard
Certain vehicles fail to conform to CMVSS 209, seat belt assemblies. These vehicles have a condition where one or two sensors in the driver's and front seat passengers seat belt retractors may be inoperative. The seat belt retractors will lock when the belt webbing is extracted during a crash; however the mechanism that locks the seat belt retractor when the vehicle decelerates quickly, such as during heavy braking, may not restrain the occupant as intended during a crash, and could result in injury to the occupant. Correction update: None required as no effect on vehicle safety. See recall 04-158.
