Loss of Steering Control

What NHTSA is examining

In the subject vehicles, the mechanical connection between the steering wheel and rack and pinion steering assembly consist of the steering column and an upper and lower intermediate shaft.A disconnection of any of these components from the steering system can create a loss of steering control.Allegations of a loss of steering control incidents reviewed during the Preliminary Evaluation PE12-025 appear to be related to a separation of the upper and lower shafts within the steering the column. In response to the Office of Defects Investigation's (ODI) Information Request (IR) during PE12-025, Ford provided 2 complaints and 9 warranty claims related to the alleged defect in the subject vehicles (see Figure 1 for an exemplar picture).ODI has received 5 complaints related to the alleged defect, including 1 related to an incident reported in one of the Ford complaints.The incident rate involving subject vehicles is 7.7 per 100,000 vehicles (15 total incidents).Five of the 15 incident vehicles were associated with a prior history report of a frontal impact incident.ODI also analyzed field data for MY 2005 through MY 2008 non-CVPI Crown Victoria and Grand Marquis models and MY 2009 through MY 2011 CVPI models, which use a similar steering column and intermediate shaft design. This analysis identified 4 reports from Ford and 2 complaints to ODI, including 1 duplicative of a complaint provided by Ford, resulting in 5 total incidents and an incident rate of 1.1 per 100,000 vehicles…
