SEAT BELTS:FRONT:RETRACTOR
Campaign #94V015000 · Jan 21, 1994
Issue: THE THIRD ROW SAFETY BELT RETRACTORS MAY BE INSTALLED INCORRECTLY AND MAY LOCK-UP WHEN THE VEHICLE IS ON SLOPES OF LESS THAN 15 DEGREES, WHICH DOES NOT COMPLY WITH FMVSS NO. 209, "SEAT BELT ASSEMBLIES."
Risk: CONSEQUENCE OF NON-COMPLIANCE: PASSENGERS SEATED IN THESE POSITON MAYBE UNABLE TO EXTRACT AND FASTEN THEIR SEAT BELTS UNTIL THE VEHICLE IS MOVED TO A MORE LEVEL SURFACE. UNBELTED OCCUPANTS ARE MORE AT RISK OF INJURY IN THE EVENT OF A COLLISION THAN THOSE USING SAFETY BELTS.
Fix: DEALERS WILL REMOVE THIRD ROW SAFETY BELT RETRACTORS AND REINSTALL THEM PROPERLY.
SEAT BELTS:FRONT:WEBBING
Campaign #94V100000 · May 24, 1994
Issue: THE SECOND ROW, RIGHT HAND SHOULDER BELT CAN BECOME "PINCHED" BETWEEN THE SEAT AND THE DOOR FRAME PILLAR TRIM. THE SHOULDER BELT MAY NOT RETRACT PROPERLY, WHICH DOES NOT COMPLY WITH THE REQUIREMENTS OF FMVSS NO. 208, "OCCUPANT CRASH PROTECTION." THE 1994 VEHICLES HAVE AN OPTIONAL INTEGRAL (BUILT IN) CHILDSEAT INSTALLED NEXT TO THE POWER SLIDING SIDE DOOR. THE 1993 INVOLVED VEHICLES HAVE STANDARD SEATS IN THAT SAME POSITION.
Risk: IMPROPER SHOULDER BELT RETRACTION DOES NOT PROVIDE ADEQUATE PROTECTION TO THE SEAT OCCUPANT IN THE EVENT OF A SUDDEN STOP OR COLLISION.
Fix: DEALERS WILL REPLACE THE DOOR FRAME PILLAR TRIM PANEL WITH A REDESIGNED TRIM PANEL. ALSO, A CAUTION LABEL WILL BE APPLIED TO THE CHILD SEAT ADVISING THE OWNER NOT TO INSTALL THE SEAT TO THE PASSENGER SIDE OF A VEHICLE WITH A POWER SLIDING SIDE DOOR.

Issue: THE SAFETY BELT RETRACTORS FOR THE REAR CENTER POSITION ARE MISSING A PAWL SPRING AND IN CASE OF AN ACCIDENT, WILL ALLOW THE SAFETY BELT WEBBING TO EXTEND BEYOND THE MINIMUM REQUIREMENTS OF FMVSS NO. 208, "OCCUPANT CRASH PROTECTION."
Risk: IN THE EVENT OF AN ACCIDENT THE SAFETY BELT WOULD NOTRESTRAIN THE OCCUPANT, SUBJECTING THE OCCUPANT TO INCREASED RISK OF INJURIES.
Fix: DEALERS WILL INSPECT THE SAFETY BELT RETRACTOR ASSEMBLY AND REPLACE THE RETRACTOR IF THE PAWL SPRING IS MISSING.

Dealer
~$60–$95
