IN THE ALTERNATIVE, NISSAN EXTENDED THE WARRANTY OF 2005 MODELS FROM 36 TO 72 MONTHS. MY 2005 VEHICLE IS NOW EXHIBITING THE CONDITION THE CONDITION WHEREIN THE FUEL GAGE READS ONE QUARTER TANK, WHEN THE TANK IS ACTUALLY EMPTY. THIS RESULTED IN AN OUT OF FUEL INCIDENT OCCURRING ON THE HIGHWAY, A NEAR ACCIDENT AND SUBSEQUENTLY BEING STRANDED AWAITING ROADSIDE ASSISTANCE. ALTHOUGH MY VEHICLE ONLY HAS 41,000 MILES - IT HAS BEEN 78 MONTHS SINCE PURCHASE AND NISSAN IS DENYING MY REQUEST FOR COVERAGE OF THE REPAIR COST. HAD NISSAN RIGHTLY INFORMED ME OF THE CONDITION VIA INCLUSION IN THE RECALL CAMPAIGN - I WOULD HAVE HAD THE DEFECTIVE FUEL SENDING UNIT REPLACED IMMEDIATELY. INSTEAD I AM BEING FORCED TO COVER THE COST OF REPAIR FOR THIS SAFETY DEFECT. I THEREFORE AM REQUESTING REIMBURSEMENT FOR MY RELATED EXPENSES. *TR

EXPERIENCED VIBRATIONS IN THE SUSPENSION AT APPROXIMATELY 55MPH. OVER THE NEXT COUPLE OF MONTHS, THE VIBRATIONS BECAME PROGRESSIVELY WORSE. I TOOK THE TRUCK TO THE NISSAN DEALER FOR REPAIRS. I WAS TOLD THIS WAS A TRANSMISSION FAILURE CAUSED BY A DESIGN PROBLEM WHERE THE RADIATOR FLUID OVER TIME CONTAMINATES THE TRANSMISSION FLUID. THE NISSAN DEALER STATED THE REPAIRS CALLED FOR COMPLETE REPLACEMENT OF THE TRANSMISSION AND RADIATOR. THE REPAIRS WERE DONE AT A COST OF $5,375.28. SINCE THIS TRANSMISSION AND RADIATOR FAILURE WAS CAUSED BY A DESIGN PROBLEM, I CONTACTED NISSAN CONSUMER AFFAIRS TO REQUEST THAT THEY COMPENSATE ME FOR THE COST OF REPAIRS. THEY REFUSED TO COVER THE COST OF REPAIRS, STATING THAT THE WARRANTY PERIOD HAD EXPIRED. *TR

MY 2005 FRONTIER STARTED STUTTERING AND NOT ACCELERATING AS NORMAL. I WAS TRYING TO GET ONTO THE FREEWAY AND MY TRUCK WOULD NOT GO PAST ABOUT 45 MPH. I GOT OFF THE FREEWAY AND TOOK SIDE ROADS BACK HOME. AFTER NUMEROUS PHONE CALLS TO NISSAN TO TRY TO FIX THIS PROBLEM I LOOKED ONLINE AND FOUND OUT THAT THE MOST COMMON PROBLEM WITH THIS VEHICLE IS TRANSMISSION FLUID MIXING WITH COOLANT FROM THE RADIATOR AND CAUSING THE TRANSMISSION TO FAIL. I TOOK MY TRUCK TO A NISSAN DEALERSHIP WHERE THEY TOLD ME THERE WASN'T A PROBLEM WITH MY TRANSMISSION FLUID AND IT WAS FINE. I THEN TOOK MY TRUCK TO ANOTHER MECHANIC WHO TOLD ME THE PROBLEM WAS THE MIXING OF THE TWO FLUIDS. THIS PROBLEM COULD HAVE POTENTIALLY CAUSED AN ACCIDENT ON THE FREEWAY, AS MY TRUCK'S MAXIMUM SPEED WAS 20 MPH LESS THAT THE SPEED LIMIT, AND MY TRUCK COULD HAVE POTENTIALLY STOPPED ALL TOGETHER. I'M JUST GLAD NONE OF THAT HAPPENED, BUT I'M SURE SOMEONE ELSE IS NOT GOING TO BE SO LUCKY. *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.
