NHTSA investigation EA06010 is a Engineering Analysis opened on 2006-06-15 and currently closed. The subject of record is NISSAN NISSAN, which places this file inside the Office of Defects Investigation queue for NISSAN. Latest activity on this investigation was logged on 2007-10-11 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.

An Engineering Analysis like EA06010 is the deeper technical phase that follows a PE. NHTSA requests design, warranty, and field-failure data from the manufacturer, conducts its own testing when needed, and determines whether the evidence supports a safety defect finding that would compel a recall.

Investigators summarized the matter as follows: "EA06-010 WAS OPENED BASED ON INFORMATION GATHERED IN PRELIMINARY EVALUATION PE06-009. PE06-009 WAS OPENED BASED ON INFORMATION OBTAINED IN A PEER INFORMATION REQUEST AS PART OF A PRELIMINARY EVALUATION (PE05-050) OF FUEL..." 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 NISSAN files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

EA06-010 WAS OPENED BASED ON INFORMATION GATHERED IN PRELIMINARY EVALUATION PE06-009. PE06-009 WAS OPENED BASED ON INFORMATION OBTAINED IN A PEER INFORMATION REQUEST AS PART OF A PRELIMINARY EVALUATION (PE05-050) OF FUEL TANK PUNCTURE IN MODEL YEAR (MY) 2003 THROUGH 2006 NISSAN MURANO VEHICLES. IN JANUARY 2006, NISSAN SUBMITTED A DEFECT INFORMATION REPORT TO ODI THAT IDENTIFIED A DEFECT IN THE FUEL TANK SHIELDING IN APPROXIMATELY 209,000 MY 2003 THROUGH 2006 NISSAN MURANO VEHICLES. TO REMEDY THE PROBLEM, NISSAN INSTALLED SHIELDS ON THE EXPOSED FRONT SURFACES OF THE RECALLED VEHICLES. PEER DATA COLLECTED FOR MY 2004 THROUGH 2005 PACIFICA VEHICLES DURING PE05-050 INCLUDED 120 FIELD REPORTS DOCUMENTING TANK REPLACEMENTS DUE TO PUNCTURE OR DAMAGE BY ROAD DEBRIS AS PART OF A PARTS RESTRICTION PROGRAM CONDUCTED AT THE REQUEST OF THE TANK SUPPLIER (INERGY). ANALYSIS OF THE INFORMATION PROVIDED BY CHRYSLER DURING PE05-050, PE06-009 AND EA06-010 SHOW THAT THE FRONT SURFACE OF THE FUEL TANKS IN THE SUBJECT PACIFICA VEHICLES IS NOT COMPLETELY PROTECTED FROM ROAD DEBRIS BY THE FLOOR PAN OR OTHER BODY STRUCTURE. THE TANKS WERE COMPARED WITH PEER VEHICLES, INCLUDING SEVERAL IDENTIFIED BY CHRYSLER AS SHARING SIMILAR DESIGN CHARACTERISTICS (UNSHIELDED HIGH-DENSITY POLYETHYLENE PLASTIC FUEL TANKS IN A SADDLEBAG CONFIGURATION). SOME OF THE PEER DESIGNS REVIEWED BY ODI PACKAGED THE TANKS IN RECESSED CAVITIES IN THE FLOOR PAN OR USED SHIELDS TO PROTECT EXPOSED SURFACES ON THE FRONT OF THE TANK. IN GENERAL, THESE TANKS HAD THE LOWEST COMPLAINT RATES FOR TANK PUNCTURE BY ROAD DEBRIS. HOWEVER, OTHER PEER DESIGNS REVIEWED BY ODI HAD PACKAGING SIMILAR TO THE SUBJECT VEHICLES AND SOME OF THESE ALSO HAD SOME COMPLAINTS OF TANK PUNCTURE. NONE OF THE PEER VEHICLES ANALYZED BY ODI HAD TANKS PUNCTURE DATA COMPARABLE TO CHRYSLER'S FIELD REPORTS FROM ITS PART RESTRICTION PROGRAMS, SO THAT DATA COULD NOT BE USED IN PEER COMPARISONS. ANALYSIS OF THE COMPLAINT DATA SHOWS THAT THE RATE FOR THE SUBJECT

About This Investigation Type

An Engineering Analysis (EA) is the in-depth phase following a Preliminary Evaluation. NHTSA engineers conduct testing, collect data from manufacturers, and perform detailed technical analysis to determine whether a safety defect exists. An EA may lead to a voluntary recall by the manufacturer or, in rare cases, a mandatory recall order.
