PURCHASED VEHICLE IN NOVEMBER 2015. DEALER STATED VEHICLE HAD BEEN SERVICED AND NEW RADIATOR INSTALLED. IN JUNE 2016, TRANSMISSION FLUID WAS DRAINED AS REGULAR MAINTENANCE AND FLUID WAS CONTAMINATED WITH ENGINE COLLANT, THEREFORE, TRANSMISSION FLUID HAD NOT BEEN FULLY FLUSHED AND REPLACED. FLUSHED TRANSMISSION WITH NEW TRANSMISSION FLUID TO REMOVE CONTAMINATED FLUID. IN JULY 2016, THE VEHICLE WAS STATIONARY AND WOULD NOT START DUE TO A BLOWN FUSE. DETERMINED THAT CONTAMINATED FLUID HAD CORRODED THE TRANSMISSION CONTROL MODULE, CAUSING THE BLOWN FUSES AND WOULD NEED TO BE REPLACED AT A COST OF $3000. THE VEHICLE HAS 140,000 MILES ON IT THEREFORE, DOES NOT QUALIFY FOR THE CLASS ACTION LAWSUIT SETTLEMENT OR THE EXTENSION (HTTPS://WWW.NCCONSUMER.ORG/NEWS-ARTICLES/SETTLEMENT-REACHED-IN-LAWSUIT-AGAINST-NISSAN-OVER-FAILED-RADIATORS-TRANSMISSIONS.HTML) NISSAN MOTOR CORPORATION WAS AWARE OF THE ISSUE WITH THE TRANSMISSIONS OIL COOLER / RADIATOR ASSEMBLY YET CHOSE TO NOT ADDRESS THE DESIGN DEFECT BY ISSUING A RECALL OR EXTENDING THE WARRANTY TO COVER THE TRANSMISSION ISSUE. WILL NOT BE PURCHASING ANOTHER NISSAN PRODUCT DUE TO THE HANDLING OF THIS ISSUE.

RADIATOR LEAKING FLUID INTO TRANSMISSION, DESTROYED THE TRANSMISSION. HAVE TO PURCHASE A NEW ONE AND ADD AN EXTERNAL COOLING SYSTEM SO IT DOES NOT HAPPEN AGAIN. $4800. MILEAGE IS 109K. NISSAN'S FORCED EXTENDED WARRANTY EXPIRED SO NO HELP FROM THEM. THIS IS A KNOWN ISSUE BY NISSAN DUE TO FAULTY DESIGN. NISSAN ALSO SAID "IT MIGHT HAPPEN TO CERTAIN TRANSMISSIONS", BUT IN FACT HAPPENS TO ALL XTERRA TRANSMISSIONS AT LEAST FOR 2006. NISSAN HAS HAD TOO MANY ENGINE/DRIVE TRAIN ISSUES ON THE MANY NISSAN'S I HAVE PURCHASED OVER THE YEARS. I WILL NOT BE PURCHASING ANOTHER NISSAN.

TRANSMISSION FAILURE. I PURCHASED THIS VEHICLE WITH 75,000 MILES IN OCTOBER 2015. AT 84,000 MILES, I NOTICED A CLUNK AND VEHICLE SLOWED ALL THE WAY DOWN WHEN THE AUTOMATIC TRANSMISSION WAS SHIFTING INTO DRIVE AT ABOUT 45 MILES AN HOUR. I WAS DRIVING IN RUSH HOUR TRAFFIC AND THE VEHICLE SLOWED WAY DOWN EVEN THOUGH I WAS TRYING TO ACCELERATE. I WAS NEARLY REARENEDED DUE TO THE SUDDEN STALL DUE TO THE TRANSMISSION. I TOOK IT TO THE NISSAN DEALERSHIP ONLY TO FIND OUT THAT THE TRANSMISSION WAS CONTAMINATED WITH RADIATOR FLUIDS. THERE'S WAS A DEDUCTIBLE OF $3,000, WHAT A SAVINGS (SARCASM). IT WAS EXPLAINED THAT IT WAS A KNOWN PROBLEM. HOW COULD I BE RESPONSIBLE FOR SOMETHING THAT EASILY COULD HAVE BEEN PREVENTED, ESPECIALLY IF NISSA KNEW ABOUT THIS VERY COMMON PROBLEM. NISSAN REALLY HAS LET ME DOWN. I WILL NEVER BUY ANOTHER NISSAN UNLESS I AM REIMBURSED FOR MOST OF WHATI PAID. I AM ALSO EXTREMELY UPSET THAT I VERY EASILY COULD HAVE BEEN IN A SERIOUS ACCIDENT DUE TO THE SUDDEN FAILURE OF THE TRANSMISSION, ESPECIALLY AS I WAS TRYING TO ACCELERATE WHEN JUST ENTERING THE INTERSTATE WHERE THE SPEED LIMIT WAS 70 MPH AND I SUDDENLY SLOWED DOWN DUE TO THE FAILING TRANSMISSION.

IN OCTOBER 2015 I NOTICED THAT MY XTERRA WAS OVERHEATING AND THE TRANSMISSION WAS SLIPPING AT TIMES. WHEN I REMOVED THE RADIATOR CAP TO CHECK THE COOLANT, IT LOOKED FOAMY AND MILKY, LIKE A LIME SMOOTHIE.

IN OCTOBER 2015 I NOTICED THAT MY XTERRA WAS OVERHEATING AND THE TRANSMISSION WAS SLIPPING AT TIMES. WHEN I REMOVED THE RADIATOR CAP TO CHECK THE COOLANT, IT LOOKED FOAMY AND MILKY, LIKE A LIME SMOOTHIE. I THOUGHT I MIGHT HAVE A BLOWN HEAD GASKET AND TOOK THE VEHICLE TO MY MECHANIC, WHO TOLD ME ABOUT THE ISSUE WITH NISSAN RADIATOR AND TRANSMISSION CROSS-CONTAMINATION. HE TOLD ME THAT FLUSHING THE SYSTEMS WOULD NOT HELP AND THE ENTIRE COOLING SYSTEM AND TRANSMISSION WOULD NEED TO BE REPLACED TO THE TUNE OF ABOUT $6500, WHICH I DIDN'T HAVE. HE TOLD ME TO CONTACT NISSAN. UNFORTUNATELY, AT THE TIME MY XTERRA WAS DIAGNOSED, IT HAD 112,000 MILES ON IT, WHICH WAS BEYOND THE SCOPE OF NISSAN'S EXTENDED WARRANTY WHICH CAME ABOUT AS A RESULT OF THE CLASS-ACTION LAWSUIT. THE ONLY THING THEY DID FOR ME WAS GIVE ME A REFUND ON A RECALL ITEM FOR WHICH I'D PAID BEFORE THE RECALL CAME OUT. THEY ALSO OFFERED ME A "BUSINESS ASSOCIATE'S" DISCOUNT ON ANOTHER NISSAN--AS IF I'D BUY ONE AFTER THIS! BECAUSE I AM MOBILITY CHALLENGED, I MUST HAVE A VEHICLE TO GET TO WORK, DOCTORS' VISITS, ETC. I WAS FORCED TO BUY ANOTHER VEHICLE. THE PAYMENTS HAVE ME SO STRAPPED FOR CASH THAT ONCE I GET MY BILLS PAID THERE'S NOTHING LEFT FOR GROCERIES OR PET FOOD, MUCH LESS PUTTING GAS IN MY CAR! I AM SO DISGUSTED WITH NISSAN FOR PUTTING ME IN THIS POSITION I CAN'T EVEN PUT IT INTO WORDS.

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.
Mar 3, 2010
NISSAN IS RECALLING CERTAIN MODEL YEAR 2006 AND MODEL YEAR 2008 FRONTIER, XTERRA AND PATHFINDER VEHICLES. THE MOLDED FUEL TANK SHELLS CAN DEFORM, CAUSING THE FUEL SENDER FLOAT ARM TO CONTACT AN EMBOSSMENT MOLDED INTO THE TANK SHELL CAUSING THE INSTRUMENT PANEL FUEL GAUGE TO SHOW THAT THE VEHICLE HAS APPROXIMATELY ONE QUARTER TANK WHEN THE FUEL TANK IS EMPTY.
Consequence & remedy
Consequence: THIS COULD CAUSE THE VEHICLE TO RUN OUT OF GAS AND STALL IN TRAFFIC, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE FUEL LEVEL SENDING UNIT INSIDE THE FUEL TANK WITH A NEW ONE THAT HAS A MODIFIED FLOAT ARM. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR BEFORE MARCH 22, 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. OWNERS IN THE OTHER STATES WILL RECEIVE EXTENDED WARRANTY COVERAGE FOR THE SENSOR TO 10 YEARS.

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.
