NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Engineering Analysis EA17-004.
try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
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) ofMY 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.

Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Engineering Analysis EA17-004. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. Model years with a try.vin recall page link to that page's NHTSA investigations section.
What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
