On certain pickup trucks and sport utility vehicles equipped with speed control, the speed control deactivation switch may overheat, smoke, or burn.

Risk

A fire at the switch could occur.

Remedy

By letter dated september 12, 2005, owners were instructed to return their vehicles to their dealers to have the speed control deactivation switch disconnected. Owners who have had their speed control deactivated are being notified that parts will be available and advised to make an appointment to reconnect the speed control beginning in february 2006. Owners who did not have their speed control deactivated are being notified to have their system remedied beginning in february 2006. Owners are urged to avail themselves of the free disconnect service as soon as possible because of the significant risk of fire. Owners may contact ford at 1‑800‑392‑3673.

Recall number 05V388000 · Recall details

What is wrong

Vehicle description: multi-purpose vehicles. The trailer hitch assembly to the frame attaching bolts could lose the clamp load.

Risk

The trailer hitch could then separate from the vehicle.

Remedy

Dealers will replace the trailer hitch mounting bolts and nut plates.

Recall number 00V073000 · Recall details

What is wrong

Vehicle description: sport utility vehicles equipped with four-wheel-drive (4x4), 17" chrome steel wheels. The clamp load can be lost on the wheel lugs due to insufficient wheel contact area with the hub. In some cases, the contact area can deform, resulting in a loss of lug nut torque.

Risk

Loss of lug nut torque can cause vibration or separation of a wheel and tire from the vehicle.

Remedy

Dealers will re-torque the wheel lugs to proper specifications and also install a label that specifies that the wheel lugs be torqued to 110 lb-ft any time the wheel is removed.

Recall number 98V296000 · Recall details

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 the federal safety agency 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 the federal safety agency?s limited resources to best accomplish the agency?s safety mission, the petition is denied.

DP05005

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 the federal safety agency 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.
