Risk: 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.
