ENGINE AND ENGINE COOLING · Campaign 10V517000 · Oct 28, 2010
Defect: NISSAN IS RECALLING CERTAIN MODEL YEAR 2004-2006 ARMADA, TITAN, INFINITI QX56 AND MODEL YEAR 2005-2006 FRONTIER, PATHFINDER AND XTERRA VEHICLES. THE INTELLIGENT POWER DISTRIBUTION MODULE (IPDM) ASSEMBLY CONTAINS AN ENGINE CONTROL MODULE (ECM) RELAY THAT HAS A DIODE FOR ELECTRICAL CURRENT NOISE REDUCTION. THE ECM RELAY MAY ALLOW SILICON VAPOR TO FORM AND, OVER TIME, THE SILICON EVAPORATES FROM THE DIODE MOLDING WHICH CAUSES SILICON OXIDE TO DEVELOP ON THE ECM RELAY CONTACT DUE TO ARCING.
Consequence: THIS COULD CAUSE ENGINE STALLING INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE ECM RELAY INSIDE THE IPDM ASSEMBLY. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON DECEMBER 6, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

THE LOWER CONTROL LINK ASSEMBLY HAS TWO CYLINDRICAL COLLARS FORMING THE INBOARD ATTACHMENT POINTS TO THE CHASSIS. DUE TO AN IMPROPER WELDING PROCESS SOME COLLARS MAY CONTAIN WELDS THAT DO NOT MEET STRENGTH SPECIFICATIONS.
Consequence: IF THE COLLAR WELD SEPARATES, THE VEHICLE HANDLING WILL DETERIORATE, POSSIBLY RESULTING IN A VEHICLE CRASH.
Remedy: NISSAN WILL NOTIFY OWNERS AND DEALERS WILL REPLACE ANY AFFECTED LOWER LINK FREE OF CHARGE. THE SAFETY RECALL BEGAN ON JULY 12, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
