NHTSA Defect Investigation #EA03014

INADVERTENT SIDE AIR BAG DEPLOYMENT: Air Bags:Side/Window

CLOSED

no recall issued

2003 LINCOLN TOWN CAR -- 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 NHTSA that a safety-related defect does not exist. The Agency will take further action if warranted by the circumstances. See attached summary report. Investigation was initiated on August 22 2003. Closed on August 12 2004.

NHTSA Defect Investigation #PE03011

INADVERTENT SIDE AIR BAG DEPLOYMENT: Air Bags:Side/Window

CLOSED

no recall issued

2003 LINCOLN TOWN CAR -- 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. Investigation was initiated on March 14 2003. Closed on August 22 2003. For detailed information & supporting documents, see the official NHTSA page concerning investigation #PE03011 »

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.
2003 LINCOLN TOWN CAR -- 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 #PE04010

REAR AXLE FRACTURE: Power Train:Axle Assembly:Axle Shaft

RECALL »

Recall #04V328000

2003 LINCOLN TOWN CAR -- This PE was opened after ODI became aware of two allegations concerning rear axle fracture and partial wheel separation involving MY 2003 Ford Crown Victoria police interceptors (cvpi). Initially, the PE's scope involved all MY 2003 Grand Marquis, Crown Victoria, and Lincoln town cars (I. E., "panther platform") produced through January 2003. While gathering information about this issue, it became evident that the failures were confined to long-wheelbase Lincoln town cars and the cvpi's due to their unique weight distribution and usage profiles. Ford's recall addresses these vehicles. Both the company and ODI are continuing to monitor the field performance of the axles and will take appropriate action as required. Investigation was initiated on January 22 2004. Closed on July 08 2004. For detailed information & supporting documents, see the official NHTSA page concerning investigation #PE04010 »
