WASHINGTON, D.C. — GM is recalling 16,667 2009 Buick Enclave, Chevrolet Traverse, GMC Acadia and Saturn Outlook vehicles because they may have been built with a safety-belt buckle in the second or third row that's missing a rivet.

"In a vehicle crash, if the rivet is missing, the buckle may separate from the mounting strap," said the National Highway Traffic Safety Administration.

Dealers will inspect the safety-belt buckles in the second and third rows of each recalled vehicle and replace them, if necessary, free of charge.
