Engine and engine cooling
Problem: 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.
Risk: This could cause engine stalling increasing the risk of a crash.
Fix: 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.
