MY TRANSMISSION IS SLIPPING. I HAVE BEEN TOLD BY A DEALER I HAVE RADIATOR FLUID IN MY TRANSMISSION FLUID. APPARENTLY, THIS IS A KNOWN PROBLEM WITH CERTAIN MODEL YEAR NISSAN VEHICLES, DUE TO A BREAK IN A TRANSMISSION LINE THAT RUNS THROUGH THE RADIATOR. PLEASE FORCE NISSAN TO RECALL AND REPAIR THIS ISSUE!!! *TR

I TOOK MY FRONTIER TRUCK IN FOR A 120000 MILE SCHEDULE MAINTENANCE CHECK AND OIL CHANGE. THE DEAL TOLD ME THAT THE RADIATOR COOLANT AND TRANSMISSION FLUID HAD MIXED TOGETHER DUE TO A PROBLEM WITH THE RADIATOR. I WAS TOLD THAT THEY WOULD FLUSH THE RADIATOR AND TRANSMISSION AND TRY TO CLEAN OUT MOST OF THE MIXED FLUID. I WAS INFORMED THAT I NEED TO REPLACE THE RADIATOR AND TRANSMISSION MIGHT HAVE TO BE ALSO REPLACED. THE COST FOR THE REPLACEMENT WOULD BE AROUND $8400. I BEGAN TO DO SOME RESEARCH INTO THE PROBLEM AND FOUND OUT THAT NISSAN KNOW THAT THERE WAS A PROBLEM WITH THE RADIATOR AND THAT THE FLUID COULD LEAK INTO THE TRANSMISSION AND DAMAGE THE TRANSMISSION. I SAW THAT NISSAN WOULD EXTEND THE WARRANT TO COVER THE COST IF YOU HAD LESS THAT 8 YEARS AND 80000 MILES. THIS WARRANT WOULD NOW HELP ME, DUE TOT THE FACT I HAVE ALMOST 119000 MILES ON MY TRUCK. I THINK IF NISSAN KNEW ABOUT THIS PROBLEM THEY WOULD HAVE A RECALL ON ALL FRONTIERS, PATHFINDERS AND XTERRAS FROM 2005-2010 AND PAY FOR THEM TO BE FIXED . IT WILL COST ME OVER $6000 TO HAVE A NEW TRANSMISSION PUT INTO MY FRONTIER TRUCK. MY TRUCK IS A 2005 FRONTIER LE. I AM HAVING THE RADIATOR ASSY REPLACED ($991.84) OIL COOLER ASSY REPLACED ($498.49) TRANSMISSION AND COOLING SYSTEM FLUSHED ($421.52). THE 120000 MILE SERVICE A/T WILL COST ME $400. I AM GOING TO SEARCH AROUND TO SEE HOW MUCH A NEW TRANSMISSION FOR MY TRUCK WOULD COST. THE DEALER SAID THE COST FOR REPLACING MY TRANSMISSION WOULD BE $6155.14. THEY WOULD SELL ME THE TRANSMISSION FOR THEIR COST WHICH WOULD SAVE ME $925. I THINK THAT NISSAN SHOULD A LEASE HELP PAY FOR HALF OR 2/3 OF THE COST FOR ME TO GET MY TRUCK FIXED. *TR

WHILE DRIVING MY FRONTIER, THE TRANSMISSION STARTING MAKING NOISE. IT STARTED SLIPPING WHEN I WAS TAKING OFF, AFTER HAVING STOPPED FOR A RED LIGHT. THEN THE SERVICE LIGHT AND INDICATOR LIGHTS CAME ON. I COULD TELL THAT 2ND GEAR WAS GONE. THE TRUCK WAS TOWED TO A CERTIFIED NISSAN DEALER. THEY INFORMED ME THAT THE TRUCK WAS NOT COVERED UNDER WARRANTY AND GAVE ME A $5190 ESTIMATE. THIS DOES NOT INCLUDE THE $300 FOR THE RENTAL I HAVE HAD TO GET FOR THIS FIRST WEEK, OR THE $101 FOR THE TOWING AND DIAGNOSTIC TESTING. I HAVE SINCE DISCOVERED THAT THE COOLANT WAS LEAKED INTO THE TRANSMISSION AND HAS CAUSED IT TO FAIL. I HAVE ALSO LEARNED THAT HUNDREDS, IF NOT THOUSANDS, HAVE REGISTERED COMPLAINTS THAT THIS WAS DUE TO A RADIATOR FAILURE THAT WAS KNOWN BY NISSAN. I DID NOT RECEIVE A RECALL NOTICE OR ANY OTHER NOTIFICATION CONCERNING THIS PROBLEM. I CALLED NISSAN CONSUMER AFFAIRS AND RECEIVED A CASE NUMBER. AFTER 24 HRS. THEY CALLED TO TELL ME THAT THEY HAD EXTENDED THE WARRANTIES ON THE RADIATORS UP TO 8 YRS. AND 80,000 MILES, BUT THAT THEY WOULD NOT BE ABLE TO HELP ME WITH MY CASE. I HAVE SINCE FOUND OUT ONLINE THAT NISSAN DID NOT ISSUE RECALLS ON THIS. MY TRUCK HAD BEEN PROPERLY SERVICED AT MY NISSAN DEALERSHIP, AND BOTH THE RADIATOR AND TRANSMISSION WAS FLUSHED AT 30,000 AND 60,000 MILES. THE POWER-STEERING WAS ALSO FLUSHED AT 60,000 MILES. I BELIEVE MY DEALERSHIP SHOULD HAVE MADE ME AWARE OF THE PROBLEM WHEN MY TRUCK WAS IN FOR SERVICING, AND THEN I COULD HAVE HAD THE RADIATOR TAKEN CARE OF UNDER THE WARRANTY PERIOD BEFORE ALL THE TRANSMISSION DAMAGE WAS DONE. AND NISSAN SHOULD HAVE ISSUED A SAFETY RECALL, AS MY TRUCK STOPPED AT 35 MPH; AND WAS ALMOST REAR ENDED. I WOULD HAVE NORMALLY BEEN ON THE HIGHWAY, EXCEPT ONCE THE NOISE STARTED, I DECIDED TO TAKE AN ALTERNATE ROUTE IN ORDER TO GET MY VEHICLE TO A SAFE AREA. NISSAN SHOULD HAVE TO PAY FOR THIS PERIOD! *TR

BROUGHT VEHICLE IN TO MECHANIC BECAUSE OF ROUGH SOUND HAPPENING OCCASIONALLY. IT TURNS OUT IT WAS THE TRANSMISSION, AND THAT RADIATOR FLUID LEAKED INTO TRANSMISSION WHICH HAS CAUSED TRANSMISSION ISSUES. COST TO REPAIR WILL BE APPROXIMATELY $4,000. THIS SHOULD NOT HAPPEN TO A VEHICLE WITH 66,000 MILES. *TR

WAS TRAVELING AT 55MPH IN MY 2005 NISSAN FRONTIER WHEN IT WAS AS IF THE TRANSMISSION WAS PUT IN NEUTRAL. HAD TO STOP IN THE HIGHWAY, NOWHERE TO PULL OFF. AS LUCK WOULD HAVE IT WAS NEAR MY DESTINATION AND MANAGED TO GET THERE GOING ABOUT 10 TO 15MPH. IT WAS AT NIGHT SO LUCKILY NOT MUCH TRAFFIC WHEN IT OCCURRED. TOWED TO DEALERSHIP NEXT DAY AND WAS TOLD THE RADIATOR FAILED AND COOLANT WAS ALLOWED TO ENTER TRANSMISSION THUS ALSO CAUSING TRANSMISSION FAILURE. VEHICLE HAD EXCEEDED THE 80,000 MILE WARRANTY BUT ALSO FOUND OUT THAT WARRANTY HAD BEEN EXTENDED FROM THE ORIGINAL 36,000 MILE WARRANTY BECAUSE OF PROBLEMS. ONLY THE RADIATOR AND TRANSMISSION WERE ISSUED THE 80,000 EXTENDED WARRANTY, BUT MY VEHICLE HAD 95,994 MILES THUS NO WARRANTY COVERAGE, AND REPAIR COST WOULD RUN $6,900.00. CONTACTED NISSAN CONSUMER AFFAIRS BUT WAS DENIED REIMBURSEMENT. ALTHOUGH DEALERSHIP WORKED WITH ME AND GOT THE PRICE DOWN TO $4,800.00 THIS IS A MAJOR EXPENSE TO ME ON A VEHICLE THAT SHOULD HAVE BEEN TAKEN CARE OF BY THE NISSAN CORP., DUE TO THE LARGE NUMBER OF COMPLAINTS ABOUT THIS EXACT PROBLEM ON VEHICLES WITH MORE THAN 80,000 MILES. HAVE YET TO FIND ANY CONSUMER THAT HAS BEEN COMPENSATED FOR THIS PROBLEM. *TR

TRANSMISSION COOLER FAILING AND CONTAMINATING THE TRANSMISSION, REPAIRED TRANSMISSION COST WAS MORE THAT I CAN PAID, FIXED ANYWAY BUT STILL NOT 100% GOOD, HAVEN'T BOUGHT A NEW RADIATOR, DON'T WANT THE SAME PROBLEM AGAIN. *TR I HOPE THIS WILL BE A RECALL SO I CAN HAVE MY TRANSMISSION REPAIR BY NISSAN AND A RADIATOR REPLACE.

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.
