Seat belts: front: buckle assemblyReported May 24, 1995 · 658,000 vehicles affected
What is wrong
The front safety belt buckle release buttons can break. These red plastic release buttons are marked "press." if a button breaks, pieces can fall into the buckle assembly causing the buckle to operate improperly.
Risk
The safety belts would not provide adequate protection to an occupant in a vehicle crash.
Remedy
Owners should promptly check the condition and operation of both front safety belt buckles and carefully inspect the red release button for any breaks or cracks. They should ensure that both buckles are operating properly by inserting each latch plate into its buckle, tugging on the belt to make sure the latch is securely locked, and then pressing the release button. The latch plate should pop out of the buckle when the button is pressed. If either release button shows a sign of breaking or cracking or if either buckle fails to operate properly, owners should promptly contact their authorized dealer to schedule an appointment to have the buckle replaced or repaired, free of charge. The manufacturer is developing a remedy designed to prevent failure of the buttons that are not currently broken.
