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

ON 1 NOV 2001 I WAS COMING BACK FROM AJO AZ. WHEN MY ENGINE OVERHEATED AS I WAS TRYING TO PASS A VEHICLE. 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.

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.

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.
