      CLOSED
    • Date Opened: November 30, 1999
    • Date Closed: April 14, 2000
    • Recall: No recall issued

    Component(s): Structure

    Summary: From the beginning of the 1991 model year production until the middle of the 1994 model year production, Ford used a galvanized steel cable to lift and hold in stored position, the Explorer spare tire.on May 19, 1994, based on the results of Ford durability testing, Ford changed to a 4.00mm stainless steel cable.there have been over 100 incidents in which the original galvanized steel cable failed allowing the spare tire to drop from its rear storage well.one of these incidents caused a following vehicle to be involved in a collision and on six other occasions the wheel made contact with following vehicles, resulting in property damage.

  11. INVESTIGATION: LIFTGATE SUPPORT BRACKET FAILURE

    NHTSA Defect Investigation #RQ99016

    • Status:
      PENDING
    • Date Opened: July 29, 1999
    • Date Closed: N/A
    • Recall: No recall yet

    Component(s): Structure

    Summary: Summary:on August 22, 1995, Ford conducted safety recall, 95V-164, on 1992 and 1993 model year Explorer due to liftgate failures.the rear liftgate hydraulic cylinder bracket can become unattached allowing the liftgate to suddenly drop.the recall remedy was to install reinforcements on the brackets.Ford also initiated a safety improvement campaign in October 1995, for 1991-1995 model year Explorer vehicles which were not included in the recall, to install reinforcements on those bracket that were found to be loose or detached.this campaign ended in October 1996. Since November 1996, ODI has received 51 consumer complaints alleging liftgate failures caused by the bracket separation, of which 19 reported the liftgate struck the occupant causing 12 injuries.one complaint was on 1992 model year vehicle, three complaints were on 1993 model year vehicles, and 47 complaints were on 1994 model year vehicles. This rq is to determine the extent of the problem experience and the scope of safety recall 95V-164.Ford and Mazda are conducting a safety recall campaign under recall number 99V-310.001/.002.
