I WAS DRIVING ON THE HIGHWAY AND THE TRANSMISSION FAILED. IT WAS SUDDEN AND THERE WAS NO WARNING. I WAS DRIVING ALONG FINE AND ALL OF THE SUDDEN I HAD NO POWER. I WAS ABLE TO PULL OVER AND GET HELP. WHEN I TOOK THE VEHICLE INTO A REPAIR SHOP I WAS TOLD THE RADIATOR LEAKED FLUID INTO THE TRANSMISSION AND RUINED IT. I HAD TO PAY TO REPLACE BOTH THE TRANSMISSION AND THE RADIATOR. I ALSO RECEIVED A LETTER FROM NISSAN STATING THIS WAS A KNOWN DESIGN FLAW. WHEN I ASKED TO BE REIMBURSED I WAS TOLD I WAS OUTSIDE OF THE WARRANTY MILEAGE. I DISAGREE IF THE DAMAGE WAS CAUSED BY A DEFECTIVE PART, NOT WEAR AND TEAR AND NOT MISUSE OF THE VEHICLE THEY SHOULD RECALL THIS ON ALL VEHICLES REGARDLESS OF MILEAGE, ETC. I HAVE TRIED CONTACTING NISSAN SEVERAL TIMES AND I HAVE BEEN TOLD THERE IS NOTHING THEY CAN DO. THE DAMAGE COST ABOUT FIVE THOUSAND DOLLARS TO FIX AND IT ALL HAD TO COME OUT OF MY POCKET. I AM SO DISGUSTED WITH THIS COMPANY AND THE TERRIBLE WAY THEY HANDLE THEIR MISTAKES. I WILL NEVER BUY ANOTHER VEHICLE FROM THEM AND I HAVE WARNED OTHERS TO GET THEIR VEHICLES CHECKED BEFORE THEY GET STRANDED SOMEWHERE OR POSSIBLY HAVE AN ACCIDENT BECAUSE OF THE GROSS NEGLIGENCE OF NISSAN. *TR

DUE TO A KNOWN MANUFACTURING DEFECT IN THE 2005 NISSAN PATHFINDER TRANSMISSION COOLING SYSTEM, MY DAUGHTER WAS STRANDED BY A VEHICLE THAT WOULDN'T MOVE. AFTER RESEARCHING THE PROBLEM I HAVE FOUND THAT THIS IS A FAIRLY COMMON PROBLEM IN THE 2005 YEAR MODEL. THERE IS A PROBLEM WITH THE ENGINE COOLING SYSTEM AND THE TRANSMISSION MIXING FLUIDS, THEREBY CAUSING CATASTROPHIC DAMAGE TO THE TRANSMISSION. LEADING UP TO THE TRANSMISSION FAILURE, THE TRANSMISSION MAY FAIL TO SHIFT OR IT MAY DOWNSHIFT AT HIGHWAY SPEEDS CAUSING OVERSPEEDING OF THE ENGINE. *TR

MY 2005 PATHFINDER'S TRANSMISSION SLIPPED. FOUND OUT THAT MY RADIATOR HAD FAILED AND MIXED RADIATOR AND TRANSMISSION FLUID. NISSAN KNEW THIS WAS A PROBLEM AND INSTEAD OF RECALLING, THEY EXTENDED WARRANTY UNTIL 80,000 OR FEB, 2013 BUT DID NOT NOTIFY ANYONE OF THE POSSIBLE PROBLEM. MY CAR HAS 86,600 MILE ON IT. NISSAN WILL NOT COVER OR PAY ANY PART OF THE REPAIR. IT IS ALL OVER WEB DISCUSSION BOARDS AND ON CONSUMERAFFAIRS.COM AND EDMONDS.COM FROM OTHER WITH THE SAME PROBLEM AND RESULT WITH NISSAN CORPORATE. WHEN WILL NISSAN END UP OWNING UP TO THIS DEFECT AND PAY FOR FIXES. IT IS AN EXPENSIVE REPAIR THAT MANY ARE HAVING TO PAY. I WILL BE SENDING A FORMAL COMPLAINT TO NISSAN AND TO CONSUMER AFFAIRS BOARDS BUT SOMEONE NEEDS TO STEP UP AND GET NISSAN TO OWN UP TO THE PROBLEM. *TR

I OWN A 2005 NISSAN PATHFINDER AND AT 81,500 MILES BEGAN EXPERIENCING TRANSMISSION VIBRATION WHILE TRAVELING BETWEEN 40-45 MPH. DURING THIS VIBRATION, MY ACCELERATION ABILITIES WERE LIMITED. THE TRANSMISSION VIBRATION WAS THE RESULT OF DEFECTIVE RADIATOR WHICH CAUSED RADIATOR FLUID AND TRANSMISSION FLUID TO MIX. I RECEIVED A LETTER FROM NISSAN INFORMING ME THAT THE WARRANTY ON THE RADIATOR ASSEMBLY OF MY 2005 PATHFINDER IS BEING EXTENDED BECAUSE 'A CRACK IN THE RADIATOR ASSEMBLY MIGHT OCCUR AT HIGHER MILEAGES LEADING TO INTERNAL LEAKAGE OF ENGINE COOLANT.' THE RADIATOR AND TRANSMISSION HAVE SINCE BEEN REPAIRED AND NISSAN IS UNWILLING TO REIMBURSE THE COST OF THE REPAIRS. AS THE RADIATOR FAILURE AND AFFECTED TRANSMISSION IS A WELL KNOW ISSUE BY NISSAN AND THE NISSAN CONSUMER COMMUNITY, NISSAN SHOULD BE RESPONSIBLE FOR ALL COSTS TO REPAIR THE RADIATOR AND AFFECTED COMPONENTS. NISSAN BEING RESPONSIBLE IS EVER MORE EVIDENT BY THE FACT THAT THE TRANSMISSION IS AFFECTED, WHICH CAUSES INTERMITTENT ACCELERATION ISSUES. *TR

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.

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.
