The defect
The front suspension control arms were assembled with ball joints which may contain sockets that were not properly heat-treated. This may cause the socket to wear rapidly and allow the ball joint stud to separate from the socket, causing either the left or right wheel suspension to collapse.
The remedy
Dealer will inspect and, where necessary, will replace the ball joints without charge to owner.
