  Date Added:

  Manufacturer:

  GMC

  Summary

  Special Coverage - If a driver repeatedly sits on the seat belt cable cover located at the base of the driver?s seat when entering the vehicle, it may cause the seat belt pretensioner to bend sharply over the seat side shield.  If this continues to occur over an extended period of time, which is very rare, the seat belt pretensioner cable may fatigue and eventually separate, which could reduce the effectiveness of the vehicle?s seat belts.  Before any damage occurs to the pretensioner cable itself, signs of wear will be visible on the pretensioner cable cover where it has been repeatedly bent over the seat side shield. Dealers are to replace the pretensioner and side shield for all customers that experience a broken pretensioner cable or come to a dealership with excessive wear on the cable sleeve. The repairs will be made at no charge to the customer.
