As with before, the vehicles were built with rear axle cross pins that may not have been heat treated. As a result, the pieces could fracture and move out of position. If this happens, the defect could actually cause the rear axle to lock up while driving. Needless to say, the problem could easily cause an accident.
GM will replace the pins free of charge, though the recall isn't scheduled to get underway until January 25. The company says that while one owner did experience a loss of power to the rear axle as a result of the defect, no accidents have been reported.
