NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE09-022.
ON MAY 4, 2009, THE OFFICE OF DEFECTS INVESTIGATIONS (ODI) OPENED PRELIMINARY EVALUATION PE09-022 TO INVESTIGATE AN OWNER COMPLAINT (ODI NO. 10260517) ALLEGING CONTACT BETWEEN THE ATF COOLING LINE AND THE RADIATOR FAN BLADES.THE COMPLAINT INDICATED THAT THE CONTACT RESULTED IN RAPID ATF FLUID LOSS WHICH RENDERED THE VEHICLE UNDRIVEABLE.THE INCIDENT OCCURRED WITHIN THE FIRST 50 MILES OF SERVICE. IN ITS RESPONSE TO ODI'S INFORMATION REQUEST LETTER FOR PE09-062, VW INDICATED THAT THE INSTALLATION AND DESIGN OF THE ATF COOLING LINES ARE THE SAME FOR BOTH THE REGULAR PASSAT AND PASSAT CC MODELS.VW HAS NOT CHANGED THE DESIGN OR INSTALLATION OF EITHER THE LINES OR RADIATOR FAN SINCE SUBJECT VEHICLE SALES BEGAN.VOLKSWAGEN FURTHER STATED THAT IT IS NOT AWARE OF ANY OTHER INCIDENTS OF ATF LINE CONTACT WITH THE RADIATOR FAN IN THE SUBJECT VEHICLES OR ANY SIMILARLY EQUIPPED VEHICLES.VW BELIEVES THAT THE ONE INCIDENT IS AN ISOLATED CASE OF IMPROPER INSTALLATION OF THE TRANSMISSION FLUID LINES. ODI INSPECTIONS OF SEVERAL MY 2009 PASSAT VEHICLES DID NOT IDENTIFY ANY CONCERNS WITH ATF COOLER LINE ROUTING THAT COULD RESULT IN CONTACT WITH THE RADIATOR FAN BLADES.CONSIDERING THE VERY SHORT TIME IN SERVICE OF THE INCIDENT VEHICLE, IT IS LIKELY ANY SUBJECT VEHICLES WITH SIMILARLY MIS-POSITIONED ATF LINES WOULDHAVE ALREADY FAILED AND BEEN REPAIRED.THE ABSENCE OF ADDITIONAL INCIDENTS SUPPORTS VW'S ASSESSMENT THAT THE SINGLE KNOWN FAILURE WAS A RANDOM AND ISOLATED EVENT. ACCORDINGLY, THIS INVESTIGATION HAS BEEN CLOSED. THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST. THE AGENCY WILL CONTINUE TO MONITOR COMPLAINTS AND OTHER INFORMATION RELATING TO THE ALLEGED DEFECT IN THE SUBJECT VEHICLES AND TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED.

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.
