Front Subframe Corrosion Failures
Opened Dec 20, 2010
Closed Mar 17, 2011
In a January 26, 2011 Defect Information Report, Ford Motor Company (Ford) notified the National Highway Traffic Safety Administration (NHTSA) that it will conduct a safety recall to address corrosion related fractures in the front lower control arm rear attaching brackets and body mount attachments at the rear of the front subframe in approximately 425,288 model year (MY) 1999 through 2003 Ford Windstar vehicles manufactured from April 1998 to July 2003 and either sold or currently registered in the following high corrosion (Salt-Belt) states:Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Utah, Vermont, West Virginia and Wisconsin (NHTSA Recall No. 11V-030, Ford Recall No. 11S16).According to Ford, separation of a front lower control arm rear attaching bracket may result in a lower control arm separation and separations of both front subframe rear body mounts may result in separation of the steering intermediate shaft.Either condition could result in diminished vehicle directional control, increasing the risk of a crash.Dealers will inspect the lower control arm rear attachment flanges and the rear body mount sections of the subframe on the right (passenger) and left (driver) sides of the vehicle.Owners of vehicles that pass the inspection will be notified when to return for installation of reinforcement brackets to extend the durability of the front subframe assembly in affected areas in the presence of corrosion.Owners of vehicles that do not pass inspection, but can be repaired, will be offered transportation until parts become available.Repurchase offers will be extended to owners of vehicles that cannot be repaired with the reinforcement brackets.This investigation is closed.

The Office of Defects Investigation (ODI) has identified 346 complaints to ODI and Ford alleging fracture, cracking and or excessive corrosion of the front subframes in model year (MY) 1999 through 2003 Ford Windstar vehicles.Approximately 97 percent of these complaints (334) involve vehicles that have been operated in Salt Belt states, which make up approximately 60 percent of the subject vehicle sales in the United States.The front subframe, sometimes referred to as the engine cradle, is a structural component of the Windstar vehicles that carries the engine, transaxle, steering rack and certain front suspension components (e.g., lower control arm).For complaints with sufficient information to identify the location of the failure, most describe problems with the rear mounting bracket for the front passenger-side lower control arm with some related to the rear body mount attachment located in the same general area of the subframe (right-rear section near the front passenger wheel).The remainder of the reports allege fracture of the front subframe at other or, most often, unspecified locations.Almost all of the complaints that specified the side of the vehicle indicated that the problem occurred on the right/passenger side (106), with only a few indicating the left/driver side (2) or both sides (3) were affected.Ford and several complainants attributed the right-side failures to the routing of the air-conditioning lines above the front subframe on that side of the vehicle, further noting that condensation has been observed dripping onto the front subframe in the area of the affected components (the A/C drain tube is also located on the right side, near the front subframe).ODI has identified 93 complaints related to lower control arm attachments, including 80 that appear to involve complete separations.All but one of these involved vehicles from Salt Belt states.All three crash incidents appear to be related to lower control arm separations, including one road departure into a road-side sign resulting in a totalled vehicle and a lane departure into another vehicle.Almost half of the ODI complaints related to control arm separation occurred at speeds greater than 20 mph and about a quarter occurred at highway speeds.Three-quarters of these complaints allege experiencing difficulty controlling the vehicle and about 40 percent appear to have resulted in departures from the intended lane of travel.Testing by both Ford and NHTSA have demonstrated that lower control arm separation from the rear attachment bracket results in significant toe out of the affected wheel, which affects the driver's ability to control vehicle direction.According to Ford, moderate braking improved vehicle controllability by reducing the amount of toe out, possibly explaining incidents that did not allege a loss of control.ODI's analysis of complaints related to the rear body mount identified 41 complaints (ODI only).These complaints generally report experiencing progressively worsening noise concerns when turning, accelerating or braking.Although, some of the complaints that appeared to involve a complete separation of the body mount alleged difficulty steering, the effects on vehicle control from this failure mode do not appear to be as great as those resulting from control arm separation.However, ODI is seeking more information regarding two complaints which alleged that body mount failure resulted in disconnection of the steering wheel from the steering rack (one occurred during vehicle service).This investigation has been upgraded to an Engineering Analysis (EA10-007) for subject vehicles sold or currently re

In a letter dated August 26, 2010, Ford Motor Company (Ford) submitted a Defect Information Report notifying NHTSA that it will conduct a safety recall (NHTSA Recall No. 10V-385) to address a rear axle defect in model year (MY) 1998 through 2003 Ford Windstar vehicles built at the Oakville assembly plant from September 1, 1997 through February 28, 2003 and either sold or currently registered in high corrosion (Salt-Belt) states where the use of salt and other corrosive chemicals may be used to treat snow/ice covered roads.The following states are included in Ford's recall:Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin. The subject vehicles utilize a Stamped/Formed axle assembly manufactured by Benteler automotive Corporation of Galesburg, MI.According to Ford, after many years of vehicle service in the Salt-Belt states, corrosion can weaken the rear axle, making it susceptible to torsional stress.There is a risk that the combined effects of corrosion and stress can lead to cracks which, if undetected, can propagate and result in a complete fracture of the axle.A completely fractured axle can affect vehicle handling and increase the risk of a crash.To correct the safety defect, Ford will initially inspect all of the subject vehicles brought into Ford/Lincoln-Mercury dealerships for possible cracked axles.Owners of vehicles without cracked axles will be notified when to return for the installation of reinforcement brackets to extend the axle durability in the presence of corrosion.Owners who have vehicles with cracked axles will either be offered a repair or alternative transportation until parts become available. On May 13, 2010, the Office of Defects Investigation (ODI) opened PE10-016 to investigate complaints of rear axle cracking in MY 1999 through 2003 Ford Windstar minivans.Combining ODI and Ford complaint data, ODI is aware of a total 891 complaints alleging rear axle cracking in the subject vehicles.Over a third of the complaints (334) allege that the cracking progressed to a complete fracture of the rear axle, including 8 allegations of crashes resulting in 3 injuries. Approximately 57 percent of the subject vehicles (524,661) were sold in Salt-Belt states covered by Ford's recall and Ford estimates that approximately 463,000 of these remain in service.Ninety-six percent of the complaints (858) and all of the complaints alleging complete fracture were from the recall region.The action taken by Ford is sufficient to resolve the issues raised by this investigation.Accordingly, this investigation is closed.
