2002 Lincoln Town Car problems

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

This investigation identified a total of 182 reports alleging inadvertent or non-crash deployment of the side air bags.the data examined during the investigation suggest that the side air bag crash sensing system's algorithm may recognize certain non-crash incidents as deployable events.odi has not, however, identified any failed component that relates to the alleged defect in the subject vehicles.also, odi has not identified any trend in the manufacture dates of complaint vehicles that may indicate a component or vehicle-manufacturing problem.a safety-related defect trend has not been identified at this time.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 the federal safety agency that a safety-related defect does not exist.the agency will take further action if warranted by the circumstances.see attached summary report.

Odi has identified 173 complaints alleging inadvertent or non-crash deployment of side air bags on model year (my) 1999-2003 lincoln town cars.most of the complaints allege that one of the side air bags deployed while driving without any impact.analysis showed that my 2001 through early my 2003 town cars have much higher complaint and warranty claim rates (138 complaints and 120 warranty claims) than the remaining vehicles (35 complaints and 32 warranty claims).ford changed its supplier of the side crash sensors for the my 2001 town cars.ford states that the algorithm in the my 2001 town cars is different from the previous model year's design, and that it is designed to provide improved occupant protection in moderate speed side pole impacts.in december 2002 (I.e., early my 2003 vehicle production), the crash sensors were moved from the floor of vehicle to near the base of b-pillars in order to reduce the incidents of inadvertent side air bag deployments.this preliminary evaluation has been upgraded to an engineering analysis (ea03-014) for my 2001-2003 town cars built before december 2002.
