NHTSA investigation EA17004 is a Engineering Analysis opened on 2017-11-20 and currently closed. The subject of record is FORD FUSION, which places this file inside the Office of Defects Investigation queue for FORD. Latest activity on this investigation was logged on 2024-02-09 — 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 EA17004 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: "On September 28, 2016, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE16-011) to investigate claims of power steering assist loss on model year (MY) 2010 Ford Fusion vehicles. During the PE,..." 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 FORD files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

On September 28, 2016, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE16-011) to investigate claims of power steering assist loss on model year (MY) 2010 Ford Fusion vehicles. During the PE, ODI received 718 unique claims related to the alleged problem with 598 reports indicating the power steering assist failed while driving at various speeds with no warning. Ford Motor Company (Ford) provided 1,851 unique reports and 1,720 warranty claims related to the alleged problem. It should be noted that as the result of investigation PE14-030, Ford conducted a safety recall (15V-340) of MY 2011-2012 Ford Fusion and other vehicles using the same electric power assist steering unit to rectify incidents of loss of power steering assist. On November 20, 2017, PE16-011 was upgraded to this Engineering Analysis (EA17-004) to further assess the scope, frequency, and consequence of this failure. This was based on an analysis of the subject vehicle complaint data that had indicated an increased likelihood of failure as the vehicles age. At the time, the rate of occurrence of this failure was comparable to previous investigations involving loss of power steering assist including the previously mentioned PE14-030. During the EA, ODI’s analysis of the alleged defect in the subject vehicles identified the following: testing showed minor steering effort changes between “assist” and “no assist”, no root cause identified, a declining failure trend, the ramp-down or reduced assist provided when a DTC is set, a lower failure rate than the recalled Fusion vehicles, and the high age of the vehicles. A safety-related defect trend has not been identified. Accordingly, this Engineering Analysis is closed. See the attached Engineering Analysis Closing Report for details. The closing of this investigation does not constitute a finding by NHTSA that a safety defect does not exist, and ODI will take further actions if warranted by future circumstances.

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.
