NISSAN CORPORATION HAS A MANUFACTURE DEFECT IN THEIR RADIATOR WHICH CAUSES COOLANT TO LEAK INTO THE TRANSMISSION. THIS ACTION NEED A NATIONWIDE RECALL ON BOTH PARTS (RADIATOR AND TRANSMISSION). JUST LIKE TOYOTA CORPORATION HAD NATIONWIDE ATTENTION, NISSAN NEED THE SAME ORDEAL. THE VEHICLE IN QUESTION IS A 2005 NISSAN PATHFINDER. THIS VEHICLE HAS EXTENDED WARRANTY WHICH WAS NOT HONOR. QUOTED WHEN PURCHASING THE EXTENDED WARRANTY, "EVERYTHING IS COVER FROM BUMPER TO BUMPER, EVEN DOWN TO THE BOLTS". THIS IS A MISLEADING STATEMENT FROM THE WARRANTY DEPARTMENT. WARRANTY DEPARTMENT WOULD NOT HONOR THE WARRANTY DUE TO COOLANT WAS IN THE TRANSMISSION. MONEY WAS PAID FOR THIS PURPOSE, NOW THEY SAY THE WARRANTY DOES NOT COVER THIS MISHAP. AFTER RESEARCHING AND TALKING WITH SKILLS MECHANICS, IT WAS DISCOVERED THAT THE COOLANT CAME FROM A DEFECTIVE (BUSTED) RADIATOR. THE MECHANICS STATED THIS IS BECOMING A COMMON PROBLEM. *TR

AFTER TRANSMISSION FLUSH, TRANSMISSION FAILED SHORTLY THEREAFTER. REPLACED TRANSMISSION JUNE 2009. MARCH 2010 HAD VIBRATION PROBLEM AND RETURNED FOR TRANSMISSION REPAIR AGAIN. SECOND TORQUE CONVERTER REPLACED. WITHIN 1 WEEK VIBRATION ISSUE RETURNED. DEALER REVIEW CONFIRMED THAT COOLANT FROM RADIATOR HAD LEAKED INTO TRANSMISSION AND THAT RADIATOR AND TRANSMISSION NEED TO BE REPLACED. THIS WOULD BE MY SECOND TRANSMISSION, AND THIRD TORQUE CONVERTER IN LESS THAN A YEAR, DUE TO A FAULTY RADIATOR USED BY NISSAN IN '05 & '06 MODELS. *TR

IN DEC. '09, NOTICED REAR END VIBRATION AND CLINKING SOUND. THOUGHT IT MIGHT BE TRANSMISSION PROBLEM. PURE COINCIDENCE-BROUGHT IT TO DEALER FOR COOLANT FLUSH WAS TOLD THAT THERE WAS TRANS FLUID IN MY RADIATOR. CALLED MY TRANS REPAIR PEOPLE (NOT NISSAN). THEY WERE AWARE OF PROBLEM. TOLD ME THAT RADIATORS IN PATHFINDER 2005'S WERE DEFECTIVE. COOLANT LEAKED THROUGH ONE OF RADIATOR TRANS COOLERS, INTO TRANS. AND TRANS FLUID LEAKED BACK INTO RADIATOR, RENDERING BOTH IRREPARABLE. NEEDED NEW TRANS AND RADIATOR. TOLD DEALER AND NISSAN. THROUGH SEVERAL PHONE CALLS/NEGOTIATIONS,, NISSAN AGREED TO DO THE $5,000-7000 REPAIR FOR DEALER LABOR CHARGE OF $450. TOLD ME I WOULD GET MONEY BACK IF THERE WAS A RECALL. DEALER DID REPAIR. THE PROBLEM IS ALSO A SAFETY ISSUE, BECAUSE RADIATOR AND/OR TRANS CAN FAIL WHILE ON THE ROAD. COUNTLESS PATHFINDER OWNERS HAVE REPORTED THE PROBLEM TO NO AVAIL. NISSAN GETTING AWAY WITH A MAJOR DEFECT THAT COULD PROVE DANGEROUS. *TR

DEALER ADVISED TORQUE CONVERTER WAS BAD..SECOND OPINION MECHANIC ADVISED RADIATOR LEAKED INTO TRANS, AND TRANS FLUID LEAKED INTO COOLANT. COOLANT DESTROYED TRANSMISSION. LEARNED THIS HAS BEEN A ONGOING PROBLEM WITH PATHFINDERS FOR YEARS, THERE IS A WELD INSIDE THE RADIATOR THAT FAILS AND THE TWO LIQUIDS TRANSFERS. WHY WOULD THE COMPANY DESIGN A RADIATOR THAT HAS TWO LIQUIDS INSIDE THAT CAN CONTAMINATE EACH OTHER. *TR

VEHICLE HESITATES DURING OVERDRIVE AT SPEED OF @ 40-50MPH. VIBRATION OCCURS AND GEARS DO NOT PROPERLY ENGAGE. FAILURE IS DUE TO DEFECTIVE RADIATOR LEAKING FLUIDS INTO TRANSMISSION. NISSAN INSTALLED DEFECTIVE RADIATOR IN 2005 PATHFINDER. THEY REFUSE TO CORRECT THE PROBLEM LEADING TO DAMAGED TRANSMISSION! *TR

I TOOK THE CAR INTO THE DEALERSHIP, THEY TOLD ME THAT I NEEDED TO GET A NEW RADIATOR AND TRANSMISSION B/C MY RADIATOR FLUID WAS LEAKING INTO MY TRANSMISSION. THEY QUOTED ME AT $6000. I THEN TOOK MY CAR TO GET A NEW RADIATOR AND TRANSMISSION FLUSH, IT HELPED A LITTLE. MY CAR FINALLY GAVE OUT 2 WEEKS AGO. WHILE DRIVING DOWN A SIDE STREET, THENALL OF A SUDDEN THE TRANSMISSION WOULDN'T SWITCH GEARS. I TRIED PRESSING THE GAS TO GO AND THE TRANSMISSION WOULD NOT GO. THE CAR WAS STILL RUNNING, HOWEVER I COULDN'T GRAB ANY GEARS TO GO. I GOT IT TOWED TO A TRANSMISSION SHOP, THEY TOLD ME THAT MY RADIATOR FLUID IS LEAKING INTO MY TRANSMISSION WHICH MADE MY TRANSMISSION LOCK UP. THEY TOOK MY TRANSMISSION APART TO LOOK AT PARTS AND APPARENTLY EVERYTHING IS RUSTY TOGETHER, NOT TO MENTION THE "COMPUTER" IN THE TRANSMISSION IS FRIED. YOU WOULD THINK THAT NISSAN WOULD RECOGNIZE AN ISSUE WHEN THEY SEE THAT SAME PART IS ON BACKORDER B/C I AM WAITING ON A PART. WHILE READING OTHERS WITH THE SAME ISSUE, SOME HAVE BEEN ON THE HIGHWAY AND THE TRANSMISSION WENT OUT. THIS IS DEFINITELY A SAFETY ISSUE SEEING AS IF DRIVING AT HIGH SPEEDS YOU COULD POSSIBLY GET REAR ENDED BADLY. I ALMOST GOT REARENDED WHILE ONLY GOING 45MPH. *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.

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.
