1998 Ford Expedition NHTSA Defect Investigations

• Defect Investigation #EA05005 - EA05-005 is closed with Ford¿S actions in recalls 05V-017, 05V-388, and 06V-286, recalling approximately 6.7 million vehicles equipped with Texas instruments speed control deactivation switches (scds).the brake systems in these recalled vehicles generate a vacuum that can potentially cause the scds to fail and, in certain switch installation orientations, catch fire.Ford is also including the entire population of 1998 Explorers.Ford has informed ODI that testing to determine the cause of failures in the 1998 Explorers will continue after this investigation is closed.ODI believes that the vehicles exhibiting the factors causing scds failure described in this report correlate well with the observed failure rates on these vehicles by model and model year.the closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist in the non-recalled vehicles manufactured with scds that are not included in Ford¿S recalls.ODI will continue to monitor the non-recalled population for incidence of engine compartment fires.the Agency reserves the right to take further action if warranted by the circumstances.see attached closing report for details.
• Defect Investigation #DP05005 - On September 6, 2005, ODI received a petition requesting that the Agency investigate allegations of engine spark plug ejection in certain model year 1997 through 2004 Ford vehicles with Triton V-8 and V-10 engines.ODI received a total of 474 non-duplicative complaints on the subject vehicles where the complainant, or the dealer repairing the vehicle, reported that a spark plug detached from the cylinder and/or ejected from the engine.as of December 8, 2005, ODI is not aware of any allegations where the alleged defect resulted in a loss of vehicle control, a crash, an injury, or a fatality in any of the 10,319,810 subject vehicles.in addition, ODI is aware of only two incidents where the vehicle stalled without restart.information contained in the ODI consumer complaints and obtained from 72 telephone interviews with complainants showed the following:(1) 99% of the complaints were on MY 1997 to 2002 subject vehicles.(2) most the complainants reported hearing a loud pop while driving or upon starting up the vehicle followed by a loud, repetitive clicking or popping sound.(3) many of the complainants reported that the popping sound was accompanied by some loss of vehicle power; however, in 99% of the incidents reported, the vehicle did not stall.in the very few incidents where the vehicle did stall, most vehicles could be restarted.(4) only a small percentage of the complainants cited that they smelled gas or a slight burning smell when the incident occurred.(5) in all but a very few incidents, vehicle damage was limited to the engine.in one incident, the complaint reported that the fuel rail was damaged and replaced after one of the spark plugs ejected from the engine; however, the complainant reported that the damage did not result in any type of fuel leak or fire.in another incident, the only incident where a fire was alleged, the complainant reported that no fluid leak was observed, but that a fire resulted after the spark plug had ejected from the engine and he had restarted the vehicle and driven to another location.none of the complainants reported any damage to the vehicle hood.(6) only two complainants reported that they observed what appeared to be some drops of fuel coming from the cylinder where the spark plug had failed or on the spark plug itself; however, each of these complainants reported that there was no smoke or flames as a result of his incident.as the petitioner noted, and ODI¿S analysis showed, it is possible for a spark plug to detach from the engine cylinder threads in the subject vehicles.however, ODI¿S analysis of 474 complaints describing such incidents found only a very few alleged any safety-related consequences.none of these showed any evidence of a serious safety consequence.given the large population and relatively long exposure time of the subject vehicles, the complaint analysis indicates that the risk to motor vehicle safety from the alleged defect is very low.in view of the foregoing, it is unlikely that NHTSA would issue an order for the notification and remedy of the alleged defect at the conclusion of the investigation requested in the petition.therefore, in view of the need to allocate and prioritize NHTSA¿S limited resources to best accomplish the Agency¿S safety mission, the petition is denied.
• Defect Investigation #PE99060 - ODI has received five reports involving 1997 through 1999 Ford Expedition and Lincoln Navigator vehicles that allege some of the eight hitch mounting bolts either became loose or came completely out ofits retaining plate.one of the complainants indicated that while towing a trailer the hitch actually separated from the frame on the passenger's side of the vehicle when the four mounting bolts on the side came completely out.this allower the hitch and trailer to contact the pavement.inspection of the four bolts on the driver's side reveled that they were loose as well.this investigation has been opened to further study the issue.
• Defect Investigation #PE98024 - Alleged tie rod end separates from the adjustment sleeve compropision steering control
• Defect Investigation #PE01022 - Alleged that one or both front stabilizer links break contributing to vehicle oversteer and excessive body roll.
