On certain vehicles, the bolt for the height-adjustment pivot on the driver seat may be loose or stripped. As a result, the bolt could pull out of the joint and allow the seat to move in a crash.
Safety Risk
A seat that moves in a crash could create an increased risk of injury.
Corrective Actions
General Motors will notify owners by mail and instruct you to take your vehicle to a dealership to inspect and, if necessary, replace the driver's seat cushion frame.
