RECALL »

Recall #08V025000

** This defect investigation is filed under 21 related vehicle components.
2002 FORD EXCURSION -- 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. Investigation was initiated on March 22 2005. Closed on August 02 2006. For detailed information & supporting documents, see the official NHTSA page concerning investigation #EA05005 »

NHTSA Defect Investigation #DP05005

SPARK PLUG EJECTION FROM CYLINDER HEAD: Engine And Engine Cooling:Engine**

CLOSED

no recall issued

** This defect investigation is filed under 3 related vehicle components.
2002 FORD EXCURSION -- 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. Investigation was initiated on September 22 2005. Closed on January 04 2006. For detailed information & supporting documents, see the official NHTSA page concerning investigation #DP05005 »

NHTSA Defect Investigation #PE03044

ACCELERATOR PEDAL SENSOR FAILURE (ETC): Vehicle Speed Control**

CLOSED

no recall issued

** This defect investigation is filed under 2 related vehicle components.
2002 FORD EXCURSION -- The subject vehicles for this investigation include model year 2002 and 2003 Excursion and F Super Duty trucks equipped with 7.3L diesel engines and an optional power adjustable pedal (pap) feature.the subject vehicles utilize an electronic throttle control (etc) system to control engine speed and power.the accelerator pedal position sensor of the etc system was replaced under Ford's field service action (fsa) 03B03 (announced in February 2003) due to concerns that it may not operate as designed and as a result, may cause the vehicle to continue to idle or unexpectedly slow when the accelerator is applied.certain complaint and warranty information related to the vehicles involved in fsa 03B03 has not been provided by Ford, as discussed in detail in Ford's response letter (dated December 2, 2003) to ODI's preliminary evaluation information request.this additional information, which is required to adequately assess the safety implications of the alleged defect, will be obtained and analyzed during the engineering analysis phase of the investigation.the manufacturer failure report counts will be determined at that time. Investigation was initiated on September 26 2003. Closed on February 18 2004. For detailed information & supporting documents, see the official NHTSA page concerning investigation #PE03044 »

NHTSA Defect Investigation #EA04006

ACCELERATOR PEDAL SENSOR (ETC): Vehicle Speed Control:Cables**

CLOSED

no recall issued

** This defect investigation is filed under 4 related vehicle components.
2002 FORD EXCURSION -- Failure counts from ODI¿S analysis are stated above; see the additional problem experience discussion in the summary report.Ford data contained duplicative reports for 4 ODI complaints and 1 crash.three crashes were allegedly due to intermittent operation of the electronic throttle control (etc) pedal, one crash occurred when an etc disabled vehicle was struck by another motorist, one report contained no detail.the injuries were minor.an issue involving fixed etc pedals was investigated also, however failure reports and populations are not shown above; see summary report for detail.although Ford has used etc based throttle control systems for many years, the pap feature was new for MY 2002.the subject etc sensor produces two output signals which the engine management system (ems) utilizes to:1) determine fueling requirements; and 2) perform sensor diagnostics.one signal is linearly proportional to throttle pedal position; the second is a digital signal.by design, the detection of a sensor fault results in the engine returning to (or remaining at) the idle state.Ford identified a defect in the pap etc sensor which prematurely affected an output signal; the migration of internal sensor lubricant caused a loss of proportional signal.the failure mechanism is progressive and as the sensor deteriorates, the ems will detect a fault, store a fault code, illuminate a warning lamp, and the engine may remain at/return to idle.in the early stages, normal operation can be regained by pedal re-application.the failure progresses until the engine remains at idle.the engine does not stall, power assisted steering and braking systems are unaffected. Ford corrected the etc sensor defect and conducted field service action (fsa) 03B03 to replace etc pedals, addressing 50% of vehicles.at Agency request to improve completion rate, Ford extended fsa 03B03 for 6 months.based on ODI's analysis of available data, Ford's action has appropriately resolved the etc sensor proplem in the subject vehicles.the closing of the investigation does not constitute a finding by NHTSA that a safety-related defect does not exist, and should not be considered as having any precedential value or effect binding the Agency in future defect investigations. See the attached summary report for additional information. Investigation was initiated on February 23 2004. Closed on February 10 2005.
