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 fromroad 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 vehicles is about half that observed in the recalled murano vehicles and not significantly higher than some of the peer vehicles analyzed with similar design characteristics.testing by the NHTSA vehicle research and testing center (VRTC) showed differences between the murano and Pacifica fuel tank packaging and exposure to road debris thrown by the front tires.accordingly, this investigation is 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.see document file for additional information regarding this resume.
