I STARTED HAVING ISSUES WITH MY 2005 NISSAN PATHFINDER AT APPROXIMATELY 100,000 MILES. I FIRST NOTICED THE PROBLEM WITH THE HEATER. WHEN I WAS PARKED THE TRUCK WOULD NOT HEAT UP ONLY COLD AIR WITH COME OUT. NEXT PROBLEM WAS WHEN I WOULD STEP ON THE GAS PEDAL THE TRUCK WOULD JERK ALOT AND IT WOULD VIBRATE WHEN I WOULD SPEED UP. IT WAS VERY SCARY, IT ACTUALLY FELT LIKE IT WAS GOING TO CAUSE ME TO GET INTO AN ACCIDENT, THAT'S HOW TERRIBLE IT FELT. I TOOK IT TO THE NISSAN DEALER WHERE I BOUGHT THE TRUCK FOR THEM TO CHECK IT AND THEY IMMEDIATELY KNEW THAT THE PROBLEM WAS COMING FROM THE TRANSMISSION. THE COOLANT MIXED INTO THE RADIATOR CAUSING FOR THAT TO GO BAD TOO. I CALLED THE NISSAN HEADQUARTERS AFTER FINDING OUT THAT THIS ISSUE WAS EXPERIENCED BY SO MANY OTHER OWNERS OF 2005 NISSAN PATHFINDERS. THIS JOB COST ME OVER $4000. *TR

I TOOK MY PATHFINDER INTO A LOCAL SHOP BECAUSE I STARTED HEARING NOISE COMING FROM THE TRANSMISSION AT AROUND 45 MPH. I WAS INFORMED ANTIFREEZE GOT INTO MY TRANSMISSION FLUID DUE TO A RADIATOR FAILURE. THE SHOP REPLACED THE RADIATOR AND FLUSHED THE TRANNY. OVER A $600 BILL. THE SHOP HOPED IT WOULD FIX THE PROBLEM WITHOUT REBUILDING OR REPLACING THE TRANSMISSION. NO LUCK!! NOW I AM LOOKING AT ANOTHER $4000 PLUS ON SOMETHING THAT SHOULD NEVER HAVE HAPPENED. I WAS TOLD BY MANY SHOPS INCLUDING THE LOCAL DEALER THAT THIS IS A KNOWN PROBLEM. IF PROACTIVE BY THE MANUFACTURE COULD HAVE BEEN FIXED WITH REPLACEMENT OF THE RADIATOR. INSTEAD, NISSAN DECIDED TO EXTEND THE WARRANTY. NEVER INFORMING CUSTOMERS TO HAVE INSPECTED FOR PREMATURE FAILURE OF THE RADIATOR OR TRANNY. *TR

Oct 28, 2010

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.

IN THOSE AREAS OF THE COUNTRY WHICH USE HEAVY CONCENTRATIONS OF ROAD SALT IN THE WINTER, A MIXTURE OF SNOW/WATER AND SALT CAN ENTER INTO THE FRONT CRASH ZONE SENSOR (CZS) HOUSING. IF THIS OCCURS, THE CZS MAY INTERNALLY RUST RESULTING IN A SIGNAL INTERRUPTION. IF THIS HAPPENS, THE RED AIR BAG WARNING LIGHT WILL ILLUMINATE TO ALERT THE VEHICLE OPERATOR.

Consequence & remedy

Consequence: THIS ISSUE COULD RESULT IN THE NON-DEPLOYMENT OF THE DRIVER AND PASSENGER FRONT AIR BAGS IN A CRASH, INCREASING THE RISK OF PERSONAL INJURY.

Remedy: DEALERS WILL REPLACE THE FRONT CZS WITH A REDESIGNED SENSOR. THE RECALL BEGAN ON JANUARY 26, 2009. OWNERS IN THE OTHER STATES WILL RECEIVE EXTENDED WARRANTY COVERAGE FOR THE SENSOR TO 10 YEARS.

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.
