NHTSA investigation EA13004 is a Engineering Analysis opened on 2013-04-26 and currently closed. The subject of record is MERCURY GRAND MARQUIS, which places this file inside the Office of Defects Investigation queue for MERCURY. Latest activity on this investigation was logged on 2013-11-15 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.

An Engineering Analysis like EA13004 is the deeper technical phase that follows a PE. NHTSA requests design, warranty, and field-failure data from the manufacturer, conducts its own testing when needed, and determines whether the evidence supports a safety defect finding that would compel a recall.

Investigators summarized the matter as follows: "In its recall notice dated August 26, 2013, Ford Motor Company (Ford) notified NHTSA of a safety defect condition that may result in loss of steering in approximately 355,000 model year (MY) 2005 through 2011 Ford Crown..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related MERCURY files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

In its recall notice dated August 26, 2013, Ford Motor Company (Ford) notified NHTSA of a safety defect condition that may result in loss of steering in approximately 355,000 model year (MY) 2005 through 2011 Ford Crown Victoria and Mercury Grand Marquis vehicles built at the St. Thomas Assembly Plant, MY 2005 through 2007 Lincoln Town Car vehicles built at the Wixom Assembly Plant, and certain MY 2008 through 2011 Lincoln Town Car vehicles built at the St. Thomas Assembly Plant and that are currently registered or were originally sold in Connecticut, Delaware, the District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, or Wisconsin (NHTSA Recall 13V-385, Ford Recall 13S08). Ford's recall addresses a corrosion related defect in the lower intermediate shaft that may result in separation of the steering column lower bearing and loss of steering control. Ford's recall will remedy the defect condition by instructing dealers to replace the lower intermediate shaft and to inspect and repair the upper intermediate shaft and steering column lower bearing as necessary. A retaining clip will be installed if the lower bearing has separated. Ford's investigation of steering column separations in the subject vehicles identified a defect condition in the lower intermediate shaft that could result in separation of the column lower bearing. According to Ford's August 26th defect report, severe corrosion of the lower intermediate shaft may cause the lower intermediate shaft swing link joint(s) to stiffen or seize. Ford determined that forces acting on the upper intermediate shaft because of seized swing links may eventually cause the upper intermediate shaft to collapse, which may result in separation of the column lower bearing and loss of steering control.

About This Investigation Type

An Engineering Analysis (EA) is the in-depth phase following a Preliminary Evaluation. NHTSA engineers conduct testing, collect data from manufacturers, and perform detailed technical analysis to determine whether a safety defect exists. An EA may lead to a voluntary recall by the manufacturer or, in rare cases, a mandatory recall order.
