2004 Nissan Murano
4 Defect Investigations from the NHTSA
NHTSA Defect Investigations for the 2004 Nissan Murano
The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 2004 Nissan Murano, both ongoing and closed, are listed below:
ALTERNATOR FAILURE / ENGINE STALLING NHTSA Engineering Analysis #EA05006
Component(s): Electrical System
Summary: ODI received 14 reports of alleged engine stalling due to alternator failure on MY 2003-2004 Murano (subject) vehicles.all of the complaints reported that the vehicle could not be restarted after the stall occurred.based on these complaints, ODI opened PE04-077 and later upgraded to EA05-006 for the subject vehicles.during EA05-006, additional failure data were identified as noted in the failure report summary above.on July 12, 2005, Nissan notified NHTSA of a safety defect on MY 2003-2005 Murano vehicles produced from April 8, 2002 and September 24, 2004 (recall 05V-319).the notification stated that "an open circuit in the alternator can occur due to wire fatigue caused by movement of the rotor coil during rapid changes in engine speed in vehicles equipped with a continuously variable transmission (cvt).higher engine compartment temperature in the Murano compared to other Nissan models may also be a contributing factor to the wire fatigue."Nissan also reported that when this happens, the charge warning and brake warning lamps will illuminate and the battery will begin to discharge.after a short time, the engine will then enter a "fail safe" mode that limits vehicle speed.very shortly after reaching this condition, the engine will stop.NHTSA's testing, however, showed that although the warning lamps illuminate, the vehicle speed is limited to only 4-7 mph rather than what NHTSA considers a "fail safe" mode. Nissan will instruct owners to return their vehicles to any Nissan dealer for an alternator inspection and replacement, if required.note:some vehicles may have had the newly designed alternator previously installed under warranty.consequently, this investigation is closed.ODI will monitor the effectiveness of the remedy and take further action if warranted.

ALTERNATOR FAILURE/ ENGINE STALLING NHTSA Preliminary Evaluation #PE04077
Component(s): Electrical System
Summary: ODI opened PE04-077 based on 14 reports of alleged engine stalling due to alternator failure.all of the complaints reported that the vehicle could not be restarted after the stall occurred.during PE04-077, additional failure data was identified as noted in the failure report summary above. During the investigation, Nissan identified that there had been alternator warranty replacements due to an open circuit in the rotor coil caused by wire fatigue. ODI's analysis shows failure rates that are of concern to ODI and indicates that the alleged defect is continuing to occur in the subject vehicles.ODI's analysis also shows that nearly all of the alternator warranty claims submitted resulted in engine stalls and at least 25% of the engine stalls resulted in a no restart condition.however, in 71% of the warranty data submitted, ODI has not been able to determine if the consumer could restart the vehicle.this preliminary evaluation has been upgraded to an engineering analysis to further investigate this concern, to assess the potential safety-related consequences, and to determine the scope of the affected population.

FUEL TANK PUNCTURES FROM ROAD DEBRIS NHTSA Preliminary Evaluation #PE05050
Component(s): Fuel System, Gasoline:Storage:Tank Assembly
Fuel System, Other:Storage:Tank Assembly
Summary: ODI opened a preliminary evaluation based on four vehicle owner questionnaires (voq's) indicating that the fuel tanks werepunctured by road debris under normal, "non" off-road driving conditions.as of November 30, 2005, the complaint total increased to 12.Nissan supplied ODI with 31 complaints of fuel tank punctures, including 26 not previously known to ODI from the voq records. In a letter dated January 9, 2006, Nissan North America, Inc. Notified ODI of its plan to recall approximately 209,000 model year 2003 - 2006 Nissan Murano vehicles built from April 24, 2002 (start of production of MY 2003) through November 24, 2005 (including a portion of MY 2006 vehicles) to correct a deficiency in fuel tank shielding from road debris.this recall has been designated NHTSA no. 06V-003.recalled vehicles will be fitted with protective shielding for the frontal portion of the fuel tank to reduce the possibility of puncture by projectiles from the front wheels.accordingly, this investigation has been closed.

DRIVER SEAT ANCHOR FAILURE NHTSA Preliminary Evaluation #PE08065
Summary: This investigation concerns structural failure of the anchor/bracket on the left rear side of the driver's seat.the concern is that such failures may alter the driver's seated position so as to reduce effectiveness of the occupant protection system or potentially compromise vehicle control.failure of the subject anchor bracket results from metal fatigue and causes rearward tilting of the driver's seat.these failures usually occur during driver ingress but may also occur while the vehicle is being operated.the safety related concerns during actual vehicle use were not validated by this investigation.while the number of complaints of this problem is relatively high, only three very minor, undocumented injuries were reported.the reported injuries occurred during driver ingress, not while the vehicle was in motion.investigation disclosed that the apparent risk of compromise to vehicle control has not been demonstrated.investigation also disclosed that the apparent risk of collapse of the driver's seat back has not been demonstrateda safety related defect trend was not identified and this investigation has been closed.
