Recall #07V078000

** This defect investigation is filed under 21 related vehicle components.
2001 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 #PE06011

ENGINE STALLING: Engine And Engine Cooling:Engine:Diesel

CLOSED

no recall issued

2001 FORD EXCURSION -- The cam position sensor (cps) provides a critical signal to the subject vehicle (sv) engine management system, the loss of which results in an engine stall.during PE06-011, Ford stated in their response to ODI that it is continuing to investigate allegations of cps related engine stall and further advised that an update will be provided upon completion of the investigation.Ford data shows that 20% of the 716,000 svs are equipped with manual transmissions which are capable of back-driving the engine when a stall occurs; power assisted steering and braking are not lost during engine back-drive.Ford data also indicates that back-drive occurs in automatic transmission vehicles above certain road speeds.the manufacturer reports noted reference 755 unique vehicles; 2 are duplicative of ODI reports.in its review of customer and field reports, Ford identified some 800 reports alleging one or more engine stalls potentially related to a cps failure in these 755 vehicles (Ford¿S ¿a¿ category reports).ODI has not completed its review of these or other Ford reports, nor has it confirmed this count.all but one of the 9 crash allegations appear to be minor in nature although ODI is still investigating these crash/injury allegations and whether or not they involve a cps failure.based on early assessment of the approximately 166,000 subject vehicle warranty claims Ford paid, there appears to be variability in claim rates between certain sv production periods; an explanation for this has not been identified.Ford reviewed a sample of the warranty claims and indicated that about half may involve a stall due to cps failure; ODI has yet to confirm this assessment.the investigation is therefore upgraded to engineering analysis EA06-012 so that ODI can continue to investigate the scope, frequency and consequences of cps related engine stalling.

NHTSA Defect Investigation #DP05005

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

CLOSED

no recall issued

** This defect investigation is filed under 3 related vehicle components.
2001 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 #EA05004

FRONT SEAT BELT BUCKLE ASSEMBLY: Seat Belts:Front:Buckle Assembly**

CLOSED

no recall issued

** This defect investigation is filed under 2 related vehicle components.
2001 FORD EXCURSION -- During the initial recall campaign in 2001, the subject vehicles were inspected by Ford dealerships using a test tool that would detect a defective front seat outboard seat belt buckle assembly.approximately one million vehicles passed the inspection test for one or both front buckles.subsequent to the recall service action, ODI received 15 consumer reports alleging that a "passed inspection" buckle subsequently failed to latch or inadvertently unlatched during use.in addition, Ford has identified 543 owner and field reports alleging buckle failure subsequent to passing the inspection test.Ford tested and examined over 100 warranty-returned buckles and found that 44% of the buckles had no problem or a condition not related to the recall inspection (non-latch related buckle damage or foreign contamination).warranty claims were highest during the 18-month period after the start of the recall (July 2001) and have been declining during the past 24 months.over the past 12 months, Ford has received approximately 12 warranty claims per month out of a vehicle population of about one million.complaints counts are also decreasing.during the past seven months, ODI has received only two complaints. A safety-related defect has not been identified at this time and further use of Agency resources does not appear to be warranted.accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.the Agency reserves the right to take further action if warranted by the circumstances. Investigation was initiated on February 17 2005. Closed on July 06 2005. For detailed information & supporting documents, see the official NHTSA page concerning investigation #EA05004 »

NHTSA Defect Investigation #RQ04011

FRONT SEAT BELT BUCKLE ASSEMBLY: Seat Belts:Front:Buckle Assembly

CLOSED

no recall issued

2001 FORD EXCURSION -- Under recall campaign (01V227), Ford recalled approximately 1.3 million vehicles to inspect and if necessary replace the front driver and/or passenger seat belt buckle.approximately 1.1 million owners responded by taking their vehicles to a dealer for inspection of the buckle using a specialized buckle test tool.Ford reported that 829,927 vehicles had both buckles pass the tool test and another 167,336 vehicles had one buckle pass.ODI and Ford received complaints alleging seat belt buckle failure shortly after passing the original recall inspection service.complainants alleged that the buckle failed by either not latching or false-latching (partial engagement of the latch to the latch plate).a false-latched buckle may release with minor movement or impact against the buckle housing including inadvertent release while the vehicle is in motion.ODI is upgrading this recall query to an engineering analysis (EA05-004) to further analyze the field performance of those vehicles that Ford dealers passed (one or both buckles) using Ford's inspection test (997,263 vehicles). Investigation was initiated on October 22 2004. Closed on February 17 2005. For detailed information & supporting documents, see the official NHTSA page concerning investigation #RQ04011 »

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.
2001 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.
