CAMPAIGN: PASSENGER SIDE SEAT EASY-ENTRY SEAT FAILS TO LOCK. Buick Skylark 1992

THIS NOTICE IS SENT TO YOU IN ACCORDANCE WITH THE REQUIREMENTS OF THE NATIONAL TRAFFIC AND MOTOR VEHICLE ACT.

DEFECT INVOLVED

GENERAL MOTORS HAS DETERMINED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS IN CERTAIN 1992 N-BODY MODELS. THESE VEHICLES MAY EXHIBIT A CONDITION IN WHICH THE PASSENGER EASY-ENTRY SEAT ADJUSTER MAY FAIL TO FULLY LOCK INTO POSITION AFTER THE SEAT BACK HAS BEEN TILTED FORWARD AND THE SEAT SLID FORWARD AND THEN BACK TO ITS ORIGINAL POSITION TO ALLOW ENTRY OR EXIT TO OR FROM THE REAR SEAT AREA.

IF THE SEAT IS NOT FULLY LOCKED IN POSITION, THE ENTIRE SEAT ASSEMBLY COULD SLIDE FORWARD DURING A RAPID DECELERATION. IF THIS WERE TO OCCUR WHILE THE PASSENGER SEAT WAS OCCUPIED, THE RESULTANT FORWARD TRAVEL OF THE SEAT COULD RESULT IN SERIOUS INJURY TO THE OCCUPANT.

TO PREVENT THIS CONDITION FROM OCCURRING, DEALERS ARE TO REPLACE THE PASSENGER'S SIDE EASY-ENTRY SEAT ADJUSTER MECHANISM ON ALL VEHICLES INVOLVED IN THIS CAMPAIGN.
