The contact was able to drive to the residence. The vehicle was taken to an independent mechanic, who determined that the spark plug had blown out of the cylinder and determined that the spark plug needed to be replaced. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 364,000. The VIN was unavailable.

I get a warning message which indicates the the Crash Sensor is not working on my Ford truck - this component inflates the Air Bag in the event of a crash. The part number for the Crash Sensor is Motorcraft 6L3Z-14B004-AA. I attempted to purchase a replacement Crash Sensor from a local Ford dealer. I was told that Ford no longer makes this part. The parts manager suggested that I check with local aftermarket parts stores; Advance Auto Parts, AutoZone, Fisher and NAPA. Nobody makes an aftermarket Crash Sensor for my vehicle. I also searched Amazon without success. I am therefore driving a vehicle with Air Bags which will not deploy - possibly causing a fatality. It seems like the manufacturer, Ford, should be required to sell replacement Crash Sensors until they become available as an Aftermarket Product.

EA11006 · Fuel Tank Strap Failure Due To Corrosion

Opened May 4, 2011 · Closed Aug 19, 2011

Status: closed (inferred from source dates) · Fuel System, Gasoline:storage:tank Assembly; Fuel System, Gasoline:storage:tank Assembly:mounting; Fuel System, Other:storage:tank Assembly; Fuel System, Other:storage:tank Assembly:mounting

One or both of the steel straps holding up the fuel tank and attaching it to the truck frame can corrode and fail (break or separate).If one strap fails, the tank may tilt and drop and possibly contact the road surface.If both straps break, the entire tank may drop to the road.If either failure occurs while the vehicle is being driven, contact with the road can abrade the tank and create a hole from which gasoline can spill.When the tank drops, it remains attached to the vehicle only by the fuel filler hose and/or supply lines, or in rare instances, by the skid plate, if present.In some cases the weight of the tank sufficiently strained the hoses and fittings and caused separation and subsequent fuel leaks from those connections.The fire hazard created by leaking gasoline is increased by the possible presence of sparks created by the metal tank being dragged along the road.Corrosion of the straps appears to be caused by prolonged exposure to road deicers, frequently road salt, used to treat snow or ice covered roads.States in which large quantities of deicers are applied to roads during the winter season (salt belt states) account for the predominant portion of strap failures.Vehicles in these salt belt states are prone to experience corrosion related failures more frequently and earlier in a vehicle?s life cycle.Ford reports approximately 97 percent of reports it received relating to strap failure involve vehicles that were operated in these high corrosion areas, and 95 percent of the reports to NHTSA involved such vehicles.Approximately one-third of F-150 U.S. production was sold in salt belt states.ODI has included in the above counts reports it has received from consumers and reports it has received from Ford in which either the complaint involved confirmed strap corrosion or ODI's assessment of available information suggests corrosion caused the reported problem.Among the incidents reported to NHTSA, 441 involved one or both straps failing due to corrosion, 353 involved the fuel tank dropping and/or dragging on the ground, and 180 involved fuel leakage.ODI has received four reports of strap failure in which the leaking fuel ignited but self-extinguished, and one incident in which fire destroyed the vehicle and injured its driver.Ford reported the same injury incident and three other unique fire incidents, including two in which the leaking fuel ignited and fire destroyed the vehicle.There were no injuries associated with the three unique Ford incidents.Ford has agreed to conduct a recall to repair the subject vehicles.The recall will cover vehicles that were originally sold or are currently registered in salt belt states (regardless of vehicle age).The vehiclesincluded in the recall are those subject vehicles that are, or have ever been, registered in Connecticut, Delaware, Iowa, Illinois, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, or the District of Columbia.Ford's recall action appears to adequately address the problem at this time.The above vehicle population (1,340,349) includes subject vehicles originally delivered or sold in salt belt states.ODI does not know the current or historical locations of all subject vehicles.According to Ford approximately 73% of the recall population is currently registered (a 27% attrition rate).Ford is also recalling certain MY 1997-1999 F-250 vehicles (under 8,500 GVWR), and MY2002-2003 Lincoln Blackwood vehicles for the same condition, resulting in an estimated 1.1 million total vehicles

EA10001 · Inadvertent Airbag Deployment

Opened Jan 13, 2010 · Closed Apr 25, 2011

Status: closed (inferred from source dates) · Air Bags; Air Bags:frontal; Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:sensor/control MODULE-INACTIVE

ODI opened this investigation based on reports of inadvertent airbag deployment.Data provided by Ford indicated that the airbag clockspring jumper wire, which is situated inside the steering wheel assembly, was installed in a manner that would allow it to rub (abrade) against a sharp metal edge on the nearby horn plate.Because the horn plate is electrically grounded the abrasion of an airbag wire on the sharp edge could cause a short circuit condition.As a result the airbag light may illuminate and/or the airbag may inadvertently deploy.Inadvertent deployments are most likely to occur during the airbag system's self-diagnostic test that initiates when the ignition switch is turned on.Ford modified the vehicle design in late January 2006 adding a protective tape over the sharp metal edge of the horn plate.Ford made additional design changes on MY 2007 vehicles to the horn plate, the clockspring jumper, and the connector layouts to further address this issue.ODI identified 318 deployment incidents with 121 alleged injury reports from subject vehicles.All but one of the incident and injury reports occurred in vehicles built before the January 2006 modification.In addition, there was one incident and alleged injury reported in the MY 2006 Mark LT vehicles that share the same design. In letters dated February 21 and April 11, 2011, Ford announced a recall of all of the approximately 1.3 million MY 2004-2006 F-150 vehicles built prior to January 24, 2006, the date the initial vehicle modification was made.In addition, approximately 14,000 MY 2006 Mark LT vehicles built prior to January 24, 2006 will also be recalled.Vehicles built after that date, which contain the modification, are not within the recall scope.Accordingly the investigation is closed.
