VEHICLE DESCRIPTION:
Passenger vehicles and light duty trucks and vans equipped with safety
belts made by Takata Corporation.
SYSTEM:
Seat belts; belt buckles.
FAULT:
Fastener, Thread failure.
DESCRIPTION OF DEFECT:
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
Page 593 of 1333
improperly.
CONSEQUENCE OF DEFECT:
The safety belts would not provide adequate protection to an occupant
in a vehicle crash.
CORRECTIVE ACTION:
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.
NOTE:
If your vehicle is presented to an authorized dealer on an agreed upon
service date and the remedy is not provided free of charge within a
reasonable time, please contact Mitsubishi at 1-800-222-0037. Also
contact the National Highway Traffic Safety Administration's Auto
Safety Hotline at 1-800-424-9393.
