Component: SEATS

THE RECLINER MECHANISM AND THE SEAT FRAME MAY HAVE FOAM AND/OR VINYL VETWEEN THEM, CREATING A "SOFT" JOINT. THIS "SOFT" JOINT RESULTS IN LOWER THAN SPECIFIED BOLT TORQUE WHICH LEADS TO JOINT LOOSENESS, CAUSING BOLT FATIGUE AND EVENTUAL BOLT FAILURE.

Consequence & Remedy

Consequence: IF BOLT FAILURE OCCURS TO THE DRIVER'S SEAT, IT WOULD ALLOW THE SEAT BACK TO SUDDENLY RECLINE, AND COULD RESULT IN LOSS OF VEHICLE CONTROL AND A VEHICLE CRASH WITHOUT PRIOR WARNING.

Remedy: DEALERS WILL REMOVE THE FOAM AND/OR VINYL FROM BETWEEN THE RECLINER MECHANISM AND THE SEAT FRAME "SOFT" JOINT AND REPLACE THE RECLINER BOLTS.
