While driving, I came to a stop light and suddenly, the car idled high and lurched forward while my foot was on the brake, luckily, I was stopped well away from the vehicle in front of me. The car idled high and seemed to have a mind of it's own. I took the back roads home and backed into our garage. The car smelled hot, and I though I had smoked my brakes, trying to keep control of it. Later that night, I told my husband about the car's actions and he did not believe me, though my daughter who was with me at the time confirmed that the car had indeed accelerated on it's own. My husband started the car and it did idle high and get hot once again, although only parked with no one in it. He thought he knew what the problem was and we turned off the car and closed the hood and went inside to order the part. A few minutes later, we heard a couple popping noises and I opened the door that led into the garage from the basement. Smoke was coming into the house and my husband said that a flame shot over my head. The car had caught on fire under the closed hood. We called the fire department, but by the time they arrived, a good portion of the basement was on fire. The house was a total loss. My husband though that the pvc elbow under the hood was sticking closed, so that is the part we were going to order. Unsure, if that was the real cause or not. The car did not have any warning lights or any other indications of a problem before this incident.

The Office of Defects Investigation (ODI) opened an investigation concerning the loss of headlights in model year (MY) 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles. The subject vehicles share the same architecture and major components.ODI has received 636 unique reports (for all submission dates) related to the alleged defect, with owners describing a loss of both low and/or high beam headlights occurring while driving.ODI identified 4 Vehicle Owner Questionnaire ( VOQ) reports alleging minor crash or loss of control incidents due to headlight failures.Drivers alleged running off of the road due to a lack of headlights and one driver reportedly struck a deer.No injuries were indicated in the VOQ crashes.In response to ODI's Information Request (IR) letter, Ford Motor Company (Ford) responded with 4173 unique reports related to the alleged problem.There were a total of 11 crashes reported within that group as well as one injury that occurred when the vehicle struck an unseen object on the side of the road when the headlights failed. Ford also submitted 49,843 warranty claims related to headlight failures.Most reports indicate that the headlights failed without warning leaving the driver with no forward lighting, however some noted the headlights flickered or dimmed prior to turning off.Consumers also noted they were able to hold the flash to pass lever on the steering column mounted stalk to activate the high beams however this is only effective as long as the lever is physically actuated.On December 21st, 2015 Ford notified ODI that it would conduct a safety recall (15V-861) to remedy headlight failures on (MY) 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles.According to Ford, the headlights of the vehicle are controlled by the Lighting Control Module (LCM) located in the engine compartment of the vehicle.The LCM uses an internal relay, mounted to a circuit board, to control power to the headlights. The headlight relay is soldered to the circuit board at six different terminals. The original equipment LCMs were manufactured in a manner that resulted in the solder joints fatiguing and/or cracking as a result of repeated thermal cycling and/or vibration, a defect condition. The condition could be exacerbated by manufacturing quality issues such as an insufficient amount of solder, effecting the continuity between the circuit board and the relay terminal, and resulting in loss of headlights while driving.Other lighting functions are unaffected by this condition.The LCM manufacturing processes were revised to address the defect condition and Ford has been conducting a warranty extension program to cover defective LCMs since late 2013.Under the recall Ford will replace any remaining defective LCMs in recalled vehicles with remedy LCMs once they become available.See NHTSA recall 15V-861 for further details on the safety recall.The recall action initiated by Ford addresses the safety risks of concern to ODI.Accordingly, the investigation is closed.The ODI reports cited above can be reviewed at SaferCar.gov under the identification (ODI) numbers found in the attached list.

In a letter dated October 2, 2014 the Office of Defects Investigation (ODI) was initially petitioned by the North Carolina Consumers Council, Inc. requesting a defect investigation of an alleged defect condition resulting in headlight and/or exterior lighting failure on 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles.ODI analyzed Vehicle Owner Questionnaire (VOQ) complaints received from consumers and identified a total of 605 reports (for all submission dates) alleging headlight failure.The complaints indicate failures of both low beam headlights typically while driving, a defect condition that was evaluated under a prior ODI investigation (PE08066).Most consumer VOQs indicate that the headlights failed suddenly and without warning leaving the driver with no forward lighting, however some report the headlights flickered or dimmed prior to turning off.In some cases drivers were able to turn the headlights back on after a period of time while others reported the headlights would not come back on at all.Consumers noted they were able to hold the flash to pass lever on the steering column mounted stalk to activate the high beams however this is only effective as long as the lever is actuated.ODI identified 4 VOQ reports alleging minor crash or loss of control incidents due to headlight failures.Drivers indicated running off of the road due to a lack of headlights and one driver reportedly struck a deer.No injuries were indicated in the VOQ crashes.In response to ODI's April 7, 2015 Information Request letter, Ford provided data indicating it has received 3,092 complaints of failed headlights related to the Lighting Control Module (LCM), a device that controls the headlights and other lighting functions.This number includes the complaints Ford reviewed and classified as headlight failure due specifically to the LCM.Within Ford's complaints, there are 11 reports alleging a crash occurred.These drivers reported hitting objects, including other vehicles after the headlights failed causing damage to the affected vehicles.One driver was injured when their car struck an unseen object in the road, jerking the steering wheel from their hands and injuring their shoulder.In total 15 crash allegations were identified, all of which have occurred since ODI's prior evaluation of this issue.This petition has been granted.Preliminary Evaluation PE15-028 has been opened to assess the scope, frequency, and safety-related consequences of the alleged defect.The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SarchNHTSAID under the identification (ODI) numbers found in the attached list.

On July 7, 2014 the Office of Defects Investigation (ODI) opened a preliminary evaluation based on five complaints (VOQs) alleging incidents ofinterference between dislodged exhaust manifold heat shields and the lower steering shaft/knuckle, including one alleging the interference resulted in a crash on a highway entrance ramp. Since opening this investigation, ODI has received four additional owner complaints.One indicated that the shield was removed before binding could occur.The other three occurred at low speed and produced some momentary steering binding that was overcome by the driver when additional steering effort was applied.Once the shield was repaired or removed, the steering returned to normal.The single incident ODI identified as a possible crash (VOQ No. 10578715) related to this condition could not be verified and the description of the crash in the complaint was not supported by the police accident report.No additional crash allegations have been identified related to the alleged defect condition.Information provided by Ford in its September 10, 2014 response to ODI's information request letter identified 10 additional incidents resulting in a low rate of 1.6 incidents per 100,000 vehicles sold in vehicles ranging from 7 to 11 years in service.Six of these incidents were reported by a single source, a state police fleet that corrected the problems in March 2011 and has not reported any additional failures since.Ford also reported 5 warranty claims, but these incidents occurred at very low mileages and appeared to be caused by loose or missing heat shield attachment hardware rather than the corrosion condition that was the cause of the more recent incidents and the focus of this investigation.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 continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted.The following VOQs are associated with this investigation:10643753, 10615584, 10611362, 10610451, 10578715, 10479681, 10471833, 10317493.

The agency has closed this investigation based on its review of complaint reports, field and technical data provided by ford and complainant interviews. Ford found that some lighting control modules (lcm) in the subject vehicles contained defective solder joints on the printed circuit board.this condition can lead to poor headlight performance ranging from intermittent outage and dimming to eventual headlights failure.the failure does not affect other lighting functions (park, emergency flasher, brake and flash to pass lights).the agency IS aware of a total of 306 consumers complaints and no report of crash, injury or fatality.ford reports 2,074 warranty claims related to headlight failure linked to the lcm during the first three years of operation.about 12% (247) of these claims are specific to headlight failure while driving.the average warranty rate for headlight failing while driving IS low (0.05%).ford reports a slightly higher warranty rate experienced for the crown victoria police interceptor vehicles and this IS attributed to the higher duty cycle of these vehicles (headlights on for longer periods).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 will monitor this issue and reserves the right to take further action if warranted by the circumstances.

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.

- 10109070The Powertrain Control/Emissions Diagnosis (PC/ED) manual has been revised for diagnosing electronic throttle bodies (ETBs). The ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes (DTCs) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.
