NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE12-011.
On April 16, 2012 the Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE12-011) to assess the risks associated with rupture of the high pressure oil line to the fuel injectors causing an engine stall in model year (MY) 2008 International CE school buses equipped with International I-6 diesel engines.
On August 31, 2012 ODI received Navistar's response to its August 2, 2012, information request letter and identified 3 consumer complaints with one involving an oil line rupture that resulted in an engine compartment fire.
ODI also identified 470 warranty claims related to the defect.
This calculates to a warranty rate of 2.8 percent for the subject population.
Navistar has released two Technical Service Information (TSI) bulletins and two iKNow (information) articles pertaining to the high pressure hose in the I-6 engine.
Following discussions with ODI concerning the warranty rate, consumer complaints and interviews, and the risk to students resulting from a stranded bus, Navistar decided to submit recall notices (12V-473 and 12V-476) on the subject vehicles to address the high pressure hose failures.
Navistar's recall actions address the issues raised by this investigation and as a result this investigation is closed.

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.
