2005 NISSAN FRONTIER 4X4 CREW CAB. POOR DESIGN OF TAILGATE HINGE ASSEMBLY DRIVERS SIDE, APPEARS THAT WAS DESIGNED TO WITHSTAND LIGHTER TAILGATE. AS I UNDERSTAND NISSAN HAS REDESIGNED AND CHANGED TAILGATE ASSEMBLY FOR 2006 AND NEWER MODELS. MY WIFE WAS DRIVING THE TRUCK AND NOTICED THE VEHICLE FOLLOWING CAME TO A COMPLETE STOP SINCE THE TAILGATE ON MY TRUCK WAS DRAGGING ON THE ROAD AND HELD PARTIALLY STILL CONNECTED TO TRUCK BODY WITH CABLE ASSEMBLY. HINGE APPEARED CRACKED AND PULLED FROM BODY OF TRUCK. TAILGATE WAS ALWAYS IN LOCKED POSITION SINCE WE HAVE ISSUES WITH THIEVES IN OUR AREA AND WAS STILL IN LOCKED POSITION WHEN I TOOK IT OUT OF TRUCK BED. OBVIOUSLY AT HIGHER SPEEDS THE FAILURE OF THE HINGE ASSEMBLY COULD COMPROMISE THE SAFETY OF FOLLOWING VEHICLES IN THE EVENT THE TAILGATE BECAME REMOVED AND FELL OFF ONTO ROADWAY. *TR

ABOUT EVEN WITH THE OTHER VEHICLE TRANSMISSION STARTED SLIPPING AND I NOTICED THAT THE ENGINE WAS OVER HEATING. I LET OFF THE GAS AND STOPPED AS SOON AS I COULD AND WAS ALMOST REAR ENDED.AFTER STOPPING I DISCOVERED NO WATER IN RADIATOR.I FILLED IT FROM A 5 GALLON CAN OF WATER AND MADE IT TO A GAS STATION.THE MECHANIC ON DUTY TOLD ME THAT THE RADIATOR FAILED INTERNALLY AND THAT I HAD WATER AND ANTIFREEZE IN THE TRANSMISSION.MECHANIC TOLD ME THAT HE HAD SEVERAL PATHFINDERS AND A FEW FRONTIERS WITH THE SAME PROBLEM. I GOT ON LINE AND FOUND HUNDREDS OF PEOPLE WITH NISSANS HAD THE SAME COMPLAINT. I CALLED THE NISSAN DEALER AND THEY SAID THAT THAT WAS NOT THE CASE THAT THEY WOULD REPLACE THE RADIATOR AND FLUSH THE TRANSMISSION AND IT WOULD BE GOOD TO GO. ON LINE PEOPLES COMPLAINTS THAT I FOUND SAID THEY WERE TOLD THE SAME AND THE TRANSMISSIONS STILL FAILED. CAN I EXPECT A RECALL TO FIX THIS PROBLEM?THE WARANTY WAS UP AT 98,000 MILES. *TR

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 & remedy

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.

On February 29, 2012 the National Highway Traffic Safety Administration (NHTSA) received a letter petitioning the agency to conduct a defect investigation into MY 2005-2010 Nissan Pathfinder, Frontier, and Xterra vehicles [the subject vehicles] for automatic transmission failures related to failed transmission coolers.NHTSA conducted a comprehensive review of data related to this subject. Our report, documenting this review, is available in the document file for this defect petition.It will also be published in the Federal Register. Of the 2,505 referenced complaints, 638 relate to a potential hazard (unable to maintain speed, no motive power, engine stall) and 1,867 concern customer satisfaction issues including, but not limited to, repair cost, vehicle shudder and shake, and engine overheating.Taking into account the allocation of agency resources and priorities and the likelihood that additional investigation would result in a finding that an unreasonable risk to highway safety exists, we conclude that further investigation is not warranted and deny the petition.ODI Complaint ID numbers are referenced on the next page.
