MY 2005 NISSAN XTERRA TRANSMISSION WENT OUT AS I WAS DRIVING ACROSS THE CAUSEWAY AND ALMOST ENDED UP IN THE MARSH. I SEARCHED ONLINE AND THIS IS A COMMON PROBLEM WITH THE RADIATOR LEAKING INTO THE TRANSMISSION. NISSAN WAS INVOLVED IN A CLASS ACTION LAWSUIT BUT IT'S TO LATE FOR DAMAGES. I THINK THIS IS A SAFETY ISSUE AND NISSAN SHOULD HAVE RECALLED THESE VEHICLES BEFORE SOMEONE IS KILLED. *TR

THE TRANSMISSION SHAKES VIOLENTLY ON ACCELERATION. SO I DROVE THE VEHICLE TO THE DEALERSHIP FOR A DIAGNOSIS.

THE TRANSMISSION SHAKES VIOLENTLY ON ACCELERATION. SO I DROVE THE VEHICLE TO THE DEALERSHIP FOR A DIAGNOSIS. I HAVE LEARNED THAT THE RADIATOR CRACKING AND LEAKING INTO THE TRANSMISSION IS A COMMON PROBLEM FOR THE 2005 NISSAN XTERRA, AND THAT NISSAN SETTLED A LAWSUIT IN OCTOBER OF 2012. I DO NOT REMEMBER GETTING ANY INFORMATION THAT THIS MIGHT BE A PROBLEM AND I HAVE TO PAY $3000 TO GET THE TRANSMISSION AND RADIATOR REPLACED! AFTER 100,000 MILES I AM STUCK TO PAY THE COMPLETE COST OF THE REPAIRS. IS THERE ANY KIND OF RECOURSE FOR THIS PROBLEM THAT I AM UNAWARE OF? *TR

THE ENGINE STARTED TO OVERHEAT AND THE VEHICLE TRANSMISSION STARTED TO SHIFT IRRATICALLY. THERE WAS AN OILY SUBSTANCE IN THE COOLANT RESERVOIR. I CONTACTED THE DEALERSHIP AND WAS TOLD THAT THIS IS A KNOWN CONDITION REQUIRING REPLACEMENT OF THE RADIATOR AND REBUILDING OF THE TRANSMISSION. I WAS TOLD THAT SINCE THERE WAS 101000 MILES ON THE VEHICLE, THAT THE ENTIRE $3800 FOR REPAIR WOULD HAVE TO BE BORNE BY ME . I TRIED DRIIVING THE VEHICLE SEVERAL TIMES AFTERWARDS WITH THE SAME RESULT. IT HAS BEEN PARKED IN FRONT OF MY HOUSE FOR 6 MONTHS NOW AS I DON'T HAVE THE MONEY TO REPAIR. *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

WHEN THE CONSUMER CONTACTED NISSAN TO CONFIRM, HE WAS INFORMED THE VEHICLE HAD OVER 80,000 MILES AND HE WOULD HAVE TO PAY $3,000 IF HE WANTED THE REPAIRS DONE. *JB

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

COMPLETE CATASTROPHIC ENGINE FAILURE DURING RUSH HOUR TRAFFIC. LUCKILY I WAS APPROACHING A RED LIGHT AND THERE WERE CARS SLOWING AHEAD OF ME I WAS ABLE TO BRAKE SLOWLY TO A STOP WHILE I WAS NOT ABLE TO BE STEER. I HAD TO BE PUSHED TO THE SIDE OF THE ROAD BY THE HELP OF OTHERS. THE VEHICLE WAS TOWED TO THE PINNACLE NISSAN DEALERSHIP WHERE THEY INFORMED ME THAT THE TRANSMISSION AND THE RADIATOR HAS TO BE FULLY REPLACED DUE TO A FAULTY VALVE . NISSAN SAID THE VALVE THAT CONNECTS THE RADIATOR AND TRANSMISSION BROKE ALLOWING COOLANT AND ANTI FREEZE TO MIX TOGETHER AND IMMEDIATELY CATASTROPHICALLY DESTROYING BOTH COMPONENTS. I WAS INFORMED THAT THEIR WAS A CLASSACTION SUIT FOR THIS VERY REASON THAT WAS SETTLED BUT THIS IS VERY DANGEROUS IF I HAD BEEN IN A FREEWAY SITUATION. NISSAN HAS HAD NUMEROUS COMPLAINTS FOR THIS VEHICLE FOR THIS REASON. I HAVE HAD EVERY RECALL PART FOR THIS VEHICLE NEEDED TO BE REPLACED DUE TO FAULTY MANUFACTURING, THIS IS A VERY EXPENSIVE REPAIR AND IT HAS BEEN KNOWN DUE TO THE # OF COMPLAINTS ON THIS PARTICULAR PART BEING FAULTY BUT A RECALL NEEDS TO HAPPEN NOT AT THE EXPENSE OF NISSAN. I AM EXPECTED TO COVER THIS WITH A DEDUCTIBLE OF $2500.00 AT NO FAULT OF MY OWN . I AM LUCKY TO BE ALIVE. I HAVE MAINTAINED ALL NECESSARY/RECCOMENDED SERVICE OUTLINED BY NISSAN UP TILL L THIS FAILURE. THANK YOU

LUCKILY I WAS WAITING IN A DRIVE THRU WHEN THE KNOWN DEFECT OCCURRED. THE RADIATOR IS KNOWN TO CRACK AND LEAK IN TO THE TRANSMISSION MIXING BOTH THE COOLANT AND TRANSMISSION FLUID REQUIRING THE REPLACEMENT OF BOTH THE RADIATOR AND TRANSMISSION. THE FAILURE OF THE RADIATOR ALSO REQUIRES THAT THE ENGINE BE FLUSHED MULTIPLE TIMES. I RECEIVED A LETTER FROM NISSAN A FEW YEARS AGO THAT THIS IS A RARE OCCURRENCE. IT DOESN'T APPEAR THAT THEY WERE TELLING THE TRUTH. NISSAN SETTLED A CLASS ACTION SUIT SO I WILL HAVE TO PAY $2560 TO GET THE PROBLEM FIXED. BECAUSE THE PARTS HAVE TO BE ORDERED IT TAKES A WEEK OR LONGER TO GET THE CAR FIXED. THIS IS A KNOWN PROBLEM THAT AFFECTS MULTIPLE NISSAN MODELS FROM 2005 THROUGH 2010. NISSAN SHOULD BE REQUIRED TO RECALL AND FIX EVERYONE OF THE AFFECTED MODELS. *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.
Dec 29, 2008

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 CERTAIN SPORT UTILITY VEHICLES EQUIPPED WITH A NISSAN ACCESSORY TOW HITCH, INADEQUATE QUALITY OF SOME WELDED JOINTS IN THE HITCH ASSEMBLY MAY RESULT IN SEPARATION OF THE HITCH FROM THE VEHICLE WHEN BEING USED TO TOW.
Consequence & remedy
Consequence: THIS COULD RESULT IN THE TRAILER SEPARATING FROM THE VEHICLE AND CAUSE A CRASH WITHOUT WARNING.
Remedy: DEALERS WILL REPLACE THE TOW HITCHES. ON OCTOBER 17, 2005, OWNERS WERE SENT AN INTERIM LETTER ADVISING THEM NOT TO USE THE TOW HITCH UNTIL IT CAN BE REPAIRED. ANOTHER LETTER WAS SENT OUT ON NOVEMBER 21, 2005, NOTIFYING THEM TO BRING THEIR VEHICLES IN FOR REPAIR. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

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.
