NHTSA Defect Investigations for the 1993 Ford Explorer

The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 1993 Ford Explorer, both ongoing and closed, are listed below:

  1. INVESTIGATION: DRIVER DOOR ELECTRICAL FIRE

    NHTSA Preliminary Evaluation #PE96066

    Component(s): Electrical System

    Summary: The contact assembly for the remote power mirror control switch may develop a short circuit between the switch positive pad and chassis ground pad as a result of water intrusion.excess current flow resulting from the short circuit condition may overheat the remote power mirror control switch circuit board and cause a fire in the driver's door.Ford has indicated that current in excess of 15 amps can overheat the circuit board enough to cause a fire.circuit protection is provided by a 30 amp fuse.Ford is recalling all 1993-94 4-door Explorer vehicles equipped with the subject electronic option combination to install an in-line 10 amp fuse in the positive battery feed to the remote power mirror control switch assembly.no 2-door Explorer vehicles were built with the subject components.according to Ford, vehicles built prior to the recall production range were equipped with lower capacity circuit boards for the subject switch assembly that would fail from an open circuit if a similar short occurred.a new switch assembly with 10 amp fuse protection was introduced beginning with the 1995 model year Explorer.Mazda will conduct a parallel compaign (97V-083.002) to remedy the subject condition in approximately 14,000 navajo vehicles.the navajo vehicles were available in only the 2-door version which, unlike the Explorer vehicles, did use the subject option combination in that body style.

  3. INVESTIGATION: SEPARATION OF MASTER CYLINDER

    NHTSA Engineering Analysis #EA95018

    Component(s): Service Brakes, Hydraulic

    Summary: Ford continues to sudy the problem attempting to determine why stud fractures are not frequently occurring in other parts of the country.likewise, ODI continues gathering information to ascertain whether the recall scope should include other geographical areas.if evidence indicates the scope should be expanded, ODI will reopen the investigation as warranted.

  4. INVESTIGATION: BRAKE MASTER CYLINDER/BOOSTER SEPARATION

    NHTSA Preliminary Evaluation #PE95001

    • Status:
      CLOSED
    • Date Opened: January 03, 1995
    • Date Closed: June 19, 1995
    • Recall: No recall issued

    • Date Opened: February 28, 1996
    • Date Closed: July 24, 1996
    • Recall: No recall issued

    Component(s): Service Brakes, Hydraulic:Antilock

    Summary: ODI has received ond hundred seventy-three (173) consumer complaints of alleged failures or malfunctions in the braking system on certain 1993 and 1994 Ford Explorer.these alleged failures or malfunctions are reported to have caused thirty-six (36) accidents resulting from vehicle loss of directional control during braking or from the extended distance required to stop the vehicle during braking.the complainants report that the alleged failures or malfunctions occurred during braking mostly on wet or slippery roads, but also have occurred on dry roads.since ODI opened this PE based on wheel lockup complaints, we have received numerous additional complaints ab out the extended distance required to stop the subject vehicles when braking under certain road and speed conditions.in response to ODI's information request (ir) concerning wheel lockup complaints ont he subject vehicles, Ford reported receiving 416 reports (field reports, owner complaints, and subrogation claims) of wheeel lockup on 1993 and 1994 Ford Explorer, with 24 alleged accidents.in addition, Ford reported receiving 24,916 warranty claims that could relate to the alleged defect of wheel lockup during braking on the subject vehicles.an engineering analysis is warranted to determine the scope of these alleged braking system failures or malfunctions on 1993 and 1994 Ford Explorer.

    • Status:
      CLOSED
    • Date Opened: April 14, 2000
    • Date Closed: October 20, 2000
    • Recall: No recall issued

  7. INVESTIGATION: SPARE TIRE WINCH CABLE

    NHTSA Preliminary Evaluation #PE99072

    • Status:
      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.

  8. 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.

    • Date Closed: February 04, 1998
    • Recall: No recall issued

    Component(s): Structure

    Summary: NHTSA was petitioned to commence a defect investigation of the subject vehicles on January 6, 1998.the petition alleges that early model Ford Explorer Sport utility vehicles develop heavy lateral vibrations at speeds above 55 mph and when encountering bumps at low speeds.the petition further alleges that these vibrations could possibly cause loss of vehicle control.the analysis of the petition is presented in the attached notice which is published in the federal register.

    • Date Closed: April 18, 2000
    • Recall: No recall issued

    Component(s): Visibility:Defroster/Defogger System

    Summary: Based on the relatively low failure frequency measured over an extended exposure time and the fact that the great majoity of incidents are confined within the blower housing, a safety-related defect trend has not been identified at this time and further use of the Agency resources does not appear to be warranted.the closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.the Agency reserves the right to take furthe action if warranted by the circumstances.
