High Pressure Oil Line Rupture
NHTSA Preliminary Evaluation PE12011 — closed, opened 2012-04-16 and involving the INTERNATIONAL INTERNATIONAL.
NHTSA investigation PE12011 is a Preliminary Evaluation opened on 2012-04-16 and currently closed. The subject of record is INTERNATIONAL INTERNATIONAL, which places this file inside the Office of Defects Investigation queue for INTERNATIONAL. Latest activity on this investigation was logged on 2012-10-02 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
A Preliminary Evaluation like PE12011 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.
Investigators summarized the matter as follows: "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..." 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 INTERNATIONAL files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
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. 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.
About This Investigation Type
A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
