A FEW DAYS PRIOR TO THIS VEHICLE'S SHUT DOWN, I HAD NOTICED WHEN DRIVING AT EITHER 40 MPH OR 60 MPH, THE VEHICLE WOULD START TO 'VIBRATE'; THE FEEL WAS AS IF DRIVING ON THE HIGHWAY AND THE TIRES ARE DRIVING OVER THE MERIDIAN ENTERING THE BRAKE DOWN LANE.

A FEW DAYS PRIOR TO THIS VEHICLE'S SHUT DOWN, I HAD NOTICED WHEN DRIVING AT EITHER 40 MPH OR 60 MPH, THE VEHICLE WOULD START TO 'VIBRATE'; THE FEEL WAS AS IF DRIVING ON THE HIGHWAY AND THE TIRES ARE DRIVING OVER THE MERIDIAN ENTERING THE BRAKE DOWN LANE. THE ALIGNMENT WASN'T THE ISSUE. THE DAY OF INCIDENT, I WAS DRIVING ON A 50 MPH MAIN STREET, WHEN APPROACHING 40 MPH, THE VEHICLE SHUT DOWN. AFTER ABOUT 10 MINUTES, THE VEHICLE STARTED BACK UP, ENOUGH TIME TO DRIVE 5 MINUTES BACK HOME. ONCE TOWED TO THE GARAGE & AFTER INSPECTION I WAS TOLD THERE WAS A CRACK IN THE ATF LINE WHICH CAUSED COOLANT TO MIX WITH TRANSMISSION FLUID IN RESULT CAUSING MY TRANSMISSION TO FAIL. OF COURSE I JUST WENT OVER MY 100,000 ML WARRANTY, MY VEHICLE IS JUST AT 126,000 ML! I AM THE ONLY OWNER OF THIS VEHICLE & HAVE DONE WELL MAINTAINING IT. AFTER DOING RESEARCH ON THIS ISSUE, I AM DISGUSTED WITH NISSAN NOT TAKING OWNERSHIP TO THIS SITUATION! THIS MODEL ALONE HAS THE MOST COMPLAINTS WITH THIS SPECIFIC ISSUE, AND TO ONLY DO AN EXTENDED RECALL UP TO 80,000 ML IS RIDICULOUS WHEN THIS ISSUE APPEARS TO HAPPEN FROM 90,000 ML +!!!!!!! I BOUGHT THIS VEHICLE BRAND NEW, WITH THE HOPES TO HAVE IT LIVE FOR ALMOST 300,000 ML, WHICH I WAS TOLD BY THE DEALERSHIP PRIOR TO ME BUYING. THIS COMPANY USED TO HAVE A GREAT REPUTATION.....LET'S PRAY THEY TRY TO GET IT BACK. I HOPE NISSAN OWNS UP TO THIS SITUATION & IS JUST NOT SITTING AROUND UNTIL A DEATH HAPPENS TO RECALL IT! *TR

THIS IS A COMPLAINT TOWARDS NISSAN AND THERE FAILURE TO BE AND ACT AS A PROFESSIONAL CAR COMPANY. THERE SHOULD BE A RECALL ON THERE RADIATORS LEAKING INTO THE TRANSMISSION, IT HAS COSTS NUMEROUS AMOUNTS OF PEOPLE THOUSANDS OF DOLLARS TO REPLACE TRANSMISSIONS AND RADIATORS AND EVEN WHEN DONE THE PROBLEM STILL OCCURS. THE CLASS ACTION LAWSUIT THAT THEY WERE SO "NICE" ENOUGH TO AGREE ON DOES NOT HELP ANYONE WHAT SO EVER ESPECIALLY WHEN HITTING THE 100K MARK. THESE VEHICLES WERE BUILT TO LAST A LONG TIME, NOT CRAP OUT AFTER 50,000 MILES. IT'S A PROBLEM THAT NEEDS TO BE RESOLVED. *TR

MY TRUCK FELT SLUGGISH. UPON DIAGNOSIS, THERE WAS TRANSMISSION FLUID IN THE RADIATOR AND THE RADIATOR WAS REPLACED ON 5/7/14. SEVERAL WEEKS LATER, MY TRUCK STALLED, AND I HAD THE INTELLIGENT POWER DISTRIBUTION MODULE REPLACED. SEVERAL WEEKS LATER, THE SERVICE ENGINE LIGHT CAME ON. THIS TIME, THERE WERE THREE TRANSMISSION CODES. THE TRANSMISSION HAD COOLANT IN IT, AND WAS STARTING TO FAIL. NISSAN CORPORATE ONLY OFFERS AN EXTENSION OVER 100,000 ON THEIR POWERTRAIN WARRANTY WITH A $3,500 DEDUCTIBLE. WITH THE TRANSMISSION (REBUILT) BEING $3,500 AND THE RADIATOR BEING $500. IT WAS NOT WORTH IT TO GO TO THE DEALERSHIP TO GET A NEW TRANSMISSION. NISSAN FAILED TO NOTIFY THEIR CUSTOMERS IN 2007 WHEN THEY BECAME AWARE OF THE PROBLEM. IT WOULD HAVE BEEN A LOT LESS COSTLY FOR NISSAN TRUCK OWNERS TO BUY A NEW RADIATOR BEFORE IT FAILED, THEN TO HAVE ALSO LOST THEIR TRANSMISSIONS. IT LOOKS LIKE NISSAN WANTED TO AVOID A COSTLY RECALL, WHICH WILL COST THEM MORE IN LOST NEW CAR SALES IN THE FUTURE. ONE CEO LOOKS GOOD, THE NEXT ONE WILL NOT. *TR

COOLANT ENTERS INTO THE TRANSMISSION SYSTEM FROM A DEFECTIVE RADIATOR SYSTEM AND DESTROYS TRANSMISSION. NISSAN MANUFACTURER IS AWARE OF THIS, EVEN LOST A CLASS ACTION LAWSUIT, BUT HAS NOT RECALLED THE VEHICLE. AS A RESULT, OWNERS ARE NOT AWARE OF THE DEFECT UNTIL TRANSMISSION IS RUINED. NISSAN ONLY AGREED TO HELP REPAIR VEHICLES, AFTER THE FACT AND ONLY UP TO 100,000 MILES - WITH THE OWNER STILL HAVING TO PAY $3,000 TOWARD REPAIR. SINCE WE WERE NOT AWARE OF THE DEFECT, WE DIDN'T DO ANYTHING PREEMPTIVE SO WE HAD TO WAIT UNTIL OUR TRANSMISSION WAS RUINED. SINCE WE ARE BEYOND THE 100,000 MILE MARK, NISSAN WILL NOT ACCEPT ANY RESPONSIBILITY FOR REPAIR. *TR

Official recalls

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. 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.
