OUR TRUCK OVERHEATED ON 10/17/13. THE GARAGE INFORMED US THE INTERNAL RADIATOR HAD BUSTED AND HAD LEAKED ANTIFREEZE INTO THE TRANSMISSION AND TRANSMISSION FLUID INTO THE RADIATOR. ACCORDING TO THE MECHANIC IT HAD BEEN THIS WAY FOR AWHILE. THERE WAS NOTHING TO INDICATE THERE WAS A PROBLEM THIS MAJOR. NISSAN COULD NOT EXPLAIN HOW THIS COULD HAVE HAPPENED NOR WHY ONLY THAT IF WE GIVE THEM 2500 THEY WILL REPLACE THE RADIATOR AND THE TRANSMISSION. THIS RADIATOR AND TRANSMISSION ARE BOTH FACTORY INSTALLED. I THINK THIS IS A DEFINITE SAFETY ISSUE AS THIS WILL CAUSE THE ENGINE TO OVERHEAT AND THE TRANSMISSION TO GO OUT AND LEAVE YOU STRANDED. THIS IS A VERY COSTLY REPAIR THAT MOST PEOPLE CANNOT UNDERTAKE. SO FAR WE HAVE PAID $300 FOR A "BAND-AID" FIX UNTIL WE CAN FIND A WAY TO RESOLVE THIS ISSUE. THIS IS A DEFINITE PROBLEM WITH THE FRONTIER 4.0L AND IT'S ONLY FAIR TO SAY THERE IS SOMETHING WRONG WITH THE FACTORY RADIATORS. *TR

THE ENGINE OVERHEATED. WHEN I LIFTED THE HOOD I NOTICED A CREAM COLORED SUBSTANCE COMING OUT OF COOLANT RESERVOIR. HAD THE TRUCK TOWED TO NISSAN DEALER. AFTER DIAGNOSIS WAS TOLD THE TRANSMISSION FLUID AND THE COOLANT FLUID GOT MIXED TOGETHER. APPARENTLY THIS HAS HAPPEN BEFORE ON 2007 NISSAN FRONTIER ENGINES. DEALER SAID I NEEDED TO HAVE THE TRANSMISSION AND THE RADIATOR REPLACED AT A COST OF $7,000 OF WHICH THEY TOLD ME NISSAN WOULD PAY $4,000. MY COMPLAINT IS THAT NISSAN KNEW THIS WAS A PROBLEM WITH APPARENTLY NO WAY TO KEEP IT FROM HAPPENING. I FEEL NISSAN SHOULD BE RESPONSIBLE FOR THE TOTAL BILL. *TR

I WAS DRIVING WHEN MY VEHICLE SUDDENLY LOST SPEED AND WOULD NOT ACCELERATE WHEN I PRESSED THE GAS. IT EVENTUALLY STOPPED, AND WOULD NOT START BACK. THE FOLLOWING DAY, I HAD IT TOWED TO A REPUTABLE REPAIR SHOP, WHERE I WAS TOLD THAT I NEEDED A NEW TRANSMISSION AND A NEW RADIATOR, WHICH WOULD COST ME MORE THAN $6000.00. THEY EXPLAINED THAT THERE WAS A CRACK IN THE RADIATOR, THAT CAUSED THE TRANSMISSION FLUID TO MIX WITH THE COOLANT. THIS FLUID MIXTURE RUINED BOTH THE TRANSMISSION AND THE RADIATOR. BELIEVING THIS WAS AN ABSURD OCCURRENCE, I LOOKED ONLINE, AND LEARNT THIS WAS A COMMON DEFECT FOR NISSAN XTERRA, FRONTIER AND PATHFINDERS FROM 2005-2010. I CALLED THE NISSAN TOLL FREE NUMBER AND EXPLAINED MY SITUATION. I WAS GIVEN A CASE NUMBER - 11982851 - AND WAS TOLD I NEEDED TO GET THE VEHICLE DIAGNOSED AT A NISSAN DEALER. I PAID A SECOND TOWING FEE AND GOT THE VEHICLE TO THE NEAREST NISSAN DEALER, WHERE THE DIAGNOSIS WAS CONFIRMED. I CALLED BACK THE NISSAN TOLL FREE NUMBER, AND WAS TOLD THAT BECAUSE MY VEHICLE WAS OVER 100 K MILES, THEY WOULD DO NOTHING TO HELP ME. I ASKED TO TALK TO A SUPERVISOR, AND WAS TOLD NONE WAS AVAILABLE, BUT ONE WOULD CALL ME WITHIN 4-8 HOURS. THAT TIME HAS EXPIRED, AND I HAVE CALLED BACK THREE TIMES, BUT STILL HAVE NOT BEEN ABLE TO TALK TO A SUPERVISOR. FRUSTRATING TO HAVE BOUGHT A NISSAN VEHICLE RIGHT OFF THE FREIGHT TRUCK, BRAND NEW, AND HAVING TO CHANGE OUT THE TRANSMISSION SO SOON, ESPECIALLY KNOWING THE MANUFACTURERS WERE AWARE OF THE DEFECT. ALSO, I WAS NOT GIVEN ANY WARNING, AND WAS JUST DRIVING ALONG, AND HAD A FAILURE THAT COULD HAVE CAUSED A SERIOUS ACCIDENT. *TR

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.
