What NHTSA says
Source: Office of Defects Investigation, as filedOn 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. The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) numbers: 10450319 and 10455151.
A Preliminary Evaluation is the first formal stage: NHTSA has decided the complaints and other information it screened are worth a closer look, and asks the manufacturer for its own data on the condition. The summary is the agency’s own text from its investigation file, unedited; the opening and closing resumes with the full reasoning are on NHTSA’s site under this number.
What this means for an owner
Source: and what happens nextAn investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.
This one became a recall. The campaign page carries the manufacturer’s filed defect, risk and remedy, the build window and every model year covered; whether one specific vehicle is included is settled by VIN at nhtsa.gov/recalls.

Common questions
Source: NHTSA Office of Defects InvestigationIs PE12011 a recall?
No — it is the investigation that led to one. Recall 12V473000, 12V476000 is the campaign; its page carries the remedy.
Is PE12011 still open?
No. It closed on Oct 2, 2012 and led to recall 12V473000, 12V476000.
Which vehicles does PE12011 cover?
NHTSA opened it on 1 model year: 2008 International CE. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
