The second row center seat belt routing may make it difficult to position correctly on smaller passengers. If the seat belt rides up to fit around the abdomen, the risk of internal injury is increased in a crash. Dealers will cut the guide loop, remove a portion of the loop, and the remaining sides should be folded over and secured with a retainer. The recall began July 21, 2005. The GM recall number is 05037.
