GENERAL MOTORS issued a recall on multiple vehicle models

On certain vehicles, the rear axle cross pin was improperly heat treated (during the manufacturing process) and could fracture and become displaced within the rear differential. As a result the driver may hear a banging noise emanating from the rear axle. Also, if the pin shifts out of position it could create an interference and cause the rear axle to lock. This could cause a loss of vehicle control, which could result in a crash causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the rear axle cross pin.
