OUR 2006 PATHFINDER HAD STARTED SHUTTERING IN THE TRANSMISSION ABOUT A WEEK BEFORE IT JUST GAVE OUT ON THE SIDE OF THE ROAD. I TOOK IT TO AN INDEPENDENT TRANSMISSION REPAIR SHOP, WHO TOLD ME THAT THE RADIATOR FLUID HAD GOTTEN INTO THE TRANSMISSION AND RUINED IT. I DID SOME CHECKING ON THE INTERNET AND FOUND THAT I WAS NOT THE ONLY ONE THAT HAS HAD THIS PROBLEM. NISSAN HAS KNOWN THIS WAS A PROBLEM AND HAS NOT SENT ANY NOTICES OR RECALLS. I ALSO HAD ANOTHER PROBLEM RECENTLY WITH THE ECM RELAY, THAT LEFT IT ON THE SIDE OF THE ROAD. AFTER RESEARCH FOUND THAT A RECALL WAS ISSUED AND NO NOTICE WAS SENT OUT. I WAS THANKFUL THAT NISSAN REPLACED THE RELAY. WE HAVE CALL NISSAN CUSTOMER SERVICE ABOUT THE TRANSMISSION, BUT I DO NOT BELIEVE THEY WILL HELP DUE TO THE MILEAGE. THIS SHOULD HAVE BEEN ADDRESSED WHEN IT WAS DISCOVERED WITH A NEW RADIATOR AND A COMPLETE TRANSMISSION SERVICE. *TR

WHILE DOING REGULAR VEHICLE MAINTENANCE ON MY VEHICLE, FOUND COOLANT HAD LEAKED INTO MY TRANSMISSION FLUID. AS A RESULT OF FINDING THIS PROBLEM, AND NOT HAVING THE FINANCIAL RESOURCES TO FIX IT AT THE TIME, I STOPPED DRIVING THE VEHICLE ON A CONSISTENT BASIS FOR AROUND 18 MONTHS. I DID THE BEST I COULD TO FIX IT BY BYPASSING THE DEFECTIVE TRANSMISSION COOLER UNDER THE RADIATOR AND FLUSHING THE TRANSMISSION OF CONTAMINATED FLUID. SINCE DISCOVERING THIS PROBLEM I HAVE DRIVEN APPROXIMATELY 6,000 MILES, AND NOW THE TRANSMISSION IS SLIPPING BADLY AND WHEN IT SHIFTS, THE TRANSMISSION SHIFTS VERY HARD. AS A RESULT OF THIS TRANSMISSION COOLER FAILURE I AM NOW LOOKING AT BEING FORCED TO REPLACE MY TRANSMISSION. *JS

AFTER A COUPLE OF MINUTES OF INVESTIGATION ON THE INTERNET FOUND THE MASS OF FOLKS DEALING WITH THE SAME RADIATOR/TRANSMISSION FAILURE PROBLEM. I'VE GOT AN APPOINTMENT WITH THE LOCAL NISSAN DEALER THIS WEEK... WE'LL SEE WHAT HAPPENS. NHTSA PLEASE HELP THE HUNDREDS IF NOT THOUSANDS OF NISSAN OWNERS DEALING WITH THIS OBVIOUS DEFECT! *TR

AT FIRST INCIDENT, THE TRANSMISSION WOULD START SLIPPING CAUSING A VIBRATION WHILE THE OVERDRIVE WAS ON, THE VIBRATION WOULD GO AWAY WHEN OUT OF OVERDRIVE. THEN THE CAR WOULD STALL WHEN YOU WOULD TRY TO TAKE OFF AT A STOP, THE CAR WOULD NOT MOVE UNTIL YOU WOULD TURN THE CAR OFF AND CRANK IT AGAIN. AS YOU WOULD PULL OUT INTO TRAFFIC THE CAR WOULD NOT GO. THEN EVEN WITH THE CAR OUT OF OVERDRIVE WHILE AT SPEEDS AT 55 MPH OR HIGHER THE TRANSMISSION WOULD NOT WORK, YOU WOULD HAVE TO LET OFF ON THE ACCELERATOR AND WAIT ON THE RPM'S TO DROP AND THEN IT WOULD GO INTO GEAR AGAIN.I TOOK THE CAR TO A LOCAL MECHANIC AND HE ADVISED THE TROUBLE WAS IN A SOLENOID IN THE TRANSMISSION. I TOOK THE CAR TO A TRANSMISSION SHOP, THEY CHECKED THE FLUID AND SAID THERE WAS WATER IN THE TRANSMISSION FLUID, CAUSED BY A COOLANT LEAK FROM INSIDE OF RADIATOR GETTING INTO THE TRANSMISSION LINES CAUSING THE TRANSMISSION TO GO BAD DUE TO COOLANT INTO THE TRANSMISSION. *JS

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.
