THE VEHICLE WAS TOWED TO HERITAGE NISSAN (1500 VETERANS MEMORIAL HWY NE, ROME, GA 30161) WHERE IT WAS DIAGNOSED THAT THERE WAS A LEAK IN THE COOLANT AND RADIATOR THAT LEAKED INTO THE TRANSMISSION, WHICH CAUSED THE VEHICLE NOT TO START.

THE VEHICLE STARTED VIBRATING VERY ROUGHLY AND LOUDLY DURING ACCELERATION, THEN SUDDENLY THE TRANSMISSION COMPLETELY FAILED WHILE MY DAUGHTER WAS DRIVING IT ON A VERY BUSY FRONTAGE ROAD TO THE HIGHWAY. SHE WAS ABLE TO STEER IT ONTO THE SHOULDER BEFORE IT STOPPED COASTING; AND SEVERAL PEOPLE STOPPED TO HELP HER PUSH IT INTO SAFETY IN A NEARBY PARKING LOT. AFTER HAVING IT TOWED TO A REPAIR SHOP, THE MECHANIC INFORMED US THAT THE RADIATOR FLUID HAD LEAKED THROUGH CRACKS INTO THE TRANSMISSION FLUID, CAUSING IRREVERSIBLE DAMAGE TO THE TRANSMISSION. UPON RESEARCHING THE PROBLEM, WE DISCOVERED THIS WAS A KNOWN AND ACKNOWEDGED PROBLEM WITH 2005-2010 NISSAN PATHFINDERS, BUT NEITHER A RECALL NOR A WARNING WAS EVER ISSUED. WE ARE NOW BEYOND THE WARRANTY COVERAGE IN TIME AND IN MILEAGE, SO NISSAN WILL NOT COVER ANY OF THE EXPENSES TO REPAIR.
IN 2007, I PURCHASED A NEW NISSAN PATHFINDER, UNAWARE OF ANY DEFECTS. IN 2011, I BEGAN HAVING PROBLEMS WITH MY TRUCK NOT PRODUCING HEAT WHILE IT WAS IDLE. NISSAN STATED THAT THE COOLANT LOOKED DARK AND ADVISED ME THAT THEIR WAS AIR IN THE LINE. ONCE AGAIN, I'M HAVING TROUBLE WITH THE HEAT AND NOW I'M BEING TOLD THE TRANSMISSION …

IN 2007, I PURCHASED A NEW NISSAN PATHFINDER, UNAWARE OF ANY DEFECTS. IN 2011, I BEGAN HAVING PROBLEMS WITH MY TRUCK NOT PRODUCING HEAT WHILE IT WAS IDLE. NISSAN STATED THAT THE COOLANT LOOKED DARK AND ADVISED ME THAT THEIR WAS AIR IN THE LINE. ONCE AGAIN, I'M HAVING TROUBLE WITH THE HEAT AND NOW I'M BEING TOLD THE TRANSMISSION AND COOLANT FLUIDS ARE INTERMIXED, AND THAT IT WOULD COST BETWEEN $7 AND 8 THOUSAND DOLLARS BECAUSE I NEED TO REPLACE BOTH THE TRANSMISSION AND THE RADIATOR. WHEN I TOOK MY TRUCK TO NISSAN IN 2011, AND THEY KNEW THE COOLANT WAS DARK, I SHOULD HAVE BEEN MADE AWARE OF THE DEFECT WITH THE RADIATOR ASSEMBLY BECAUSE MY ISSUES MOST LIKELY HAD ALREADY STARTED, AND NOW, IT'S GOTTEN WORSE. I WAS NEVER ADVISED OF THIS PROBLEM UNTIL NOW.
I BOUGHT MY 07 PATHFINDER IN JULY AND THE DEALERSHIP HAD DONE REPAIR ON THE RADIATOR AT THEIR EXPENSE, AND REPLACED THE COOLANT AND TRANNY FLUIDS AND STATED THERE WAS NO CROSS CONTAMINATION. HOWEVER, THE VEHICLE STOPPED SHIFTING PROPERLY AND WE COULDN'T TELL IF IT WAS THE TRANNY, ABS, OR 4WD GETTING CAUGHT. AS OF YESTERDAY THE T…

I BOUGHT MY 07 PATHFINDER IN JULY AND THE DEALERSHIP HAD DONE REPAIR ON THE RADIATOR AT THEIR EXPENSE, AND REPLACED THE COOLANT AND TRANNY FLUIDS AND STATED THERE WAS NO CROSS CONTAMINATION. HOWEVER, THE VEHICLE STOPPED SHIFTING PROPERLY AND WE COULDN'T TELL IF IT WAS THE TRANNY, ABS, OR 4WD GETTING CAUGHT. AS OF YESTERDAY THE TRANNY WOULDN'T CHANGE GEARS. RESTARTING THE CAR HELPED. BUT SINCE THERE WAS NO RECALL THERE IS NO HISTORY OF ANY OTHER WORK. ALL MAINTENANCE WAS KEPT UP WITH THE SAME DEALERSHIP FOR THE MAJORITY OF THE VEHICLES LIFE. AFTER THE VEHICLE HAS BEEN AT A STOP, AND MOVED TO ACCELERATE IT WOULDN'T GO INTO GEAR/DRIVE THEN ALL OF A SUDDEN WOULD ?CATCH? AND WOULD LAUNCH.

I HAD NOTICED FLUID LEAKING FROM UNDER THE FRONT /RIGHT PORTION OF MY VEHICLE AFTER I PARKED. I OPENED THE HOOD AND THE RESERVE CAP TO THE RADIATOR HAD COME LOOSE. AFTER LETTING MY VEHICLE COOL, I INSPECTED BOTH THE RESERVE TANK AND RADIATOR AND NOTICED THE FLUID WAS NOW A MILKY/FROTHY SUBSTANCE. AFTER SOME DETECTIVE WORK, I LEARNED THAT THIS IS A COMMON ISSUE WITH PATHFINDERS FROM 2005- THROUGH 2010 THAT NISSAN HAS IGNORED TO FIX. THE TRANSMISSION FLUID COOLER IN THE RADIATOR ASSEMBLY "FAILS" CAUSING CONTAMINATION TO THE INTERNAL TRANSMISSION COMPONENTS ,AND DAMAGE TO THE INTERNAL TRANSMISSION COMPUTER. THERE ARE NO WARNING SIGNS UP TO OR JUST PRIOR TO THE FAILURES. AFTER CONTACTING NISSAN AND RECEIVING A DENIAL TO FIX OUR TRUCK UNDER A WARRANTY, I AM STUCK WITH A VEHICLE WITH SEVERAL "THOUSANDS OF DOLLARS" IN REPAIRS ALL DUE TO NISSAN IGNORING A KNOWN DEFECT AND NOT ISSUING A RECALL ON ALL VEHICLES IN THE "KNOWN" YEAR BRACKET WITH THESE ISSUES. I'M SURE NOTHING WILL BE DONE REGARDING THIS ISSUE DUE TO THERE NOT BEING A MAJOR LOSS OF LIVES INVOLVED, I.E. TAKATA AIRBAGS,BUT I FIND IT IS MY DUTY TO ADD MY NAME TO AN ALREADY HEFTY LIST OF OTHER NISSAN PATHFINDER OWNERS THAT HAVE EXPERIENCED THIS SAME PROBLEM.

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.
