Some of these vehicles have an internal component in the outboard seat belt retractors for the 2nd and 3rd row of seats that could be cracked. With repeated actuation of the locking mechanism, the crack could spread to the point such that the seat belt would no longer lock.

In a crash, increased occupant injury could result from the no-lock condition.

Dealers will inspect the outboard seat belts for specific lot numbers and replace the belts if necessary. General Motors Corp. is enclosing an inspection procedure for the owners to use or they can have their dealers do the inspections.
