NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE10-041.
try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
ODI became aware of a fire involving a Washington Metro Area Transit Authority (WMATA) bus.
A WMATA contracted vehicle inspection identified the failure of a tapped hydraulic fitting to have caused the fire. Orion VI buses were built from 1994 to 2002.
This investigation is specific to 1995, 1997-2000 production.
Daimler Bus informed ODI that 1994 & 1996 model year buses were either prototypes or sold only in Canada; buses built after 2000 had a tee fitting in lieu of the tapped fitting in question.
On October 20, 2010 Daimler Bus informed ODI that an internal meeting was planned to discuss the same concern as the one that prompted this investigation.
ODI agreed to delay formally requesting information; an IR letter was to be mailed on November 9, 2010 if needed. On November 2, 2010 ODI received a 573 Defect Report (Recall 10V-538) that addresses the concerns of this investigation.
This investigation will be closed.
There is no associated IR letter.
A copy of the defect report is attached.
Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Preliminary Evaluation PE10-041. 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.
