I WAS DRIVING MY 2005 NISSAN XTERRA DOWN THE HIGHWAY AROUND 65MPH WHEN I NOTICED THE VEHICLE WOULD NOT ACCELERATE WHEN PUSHING THE GAS PEDAL. I WAS ABLE TO MANEUVER THE VEHICLE OFF THE ROAD JUST BEFORE THE STEERING WHEEL LOCKED UP & THE VEHICLE WENT DEAD. HAD IT TOWED INTO DEALERSHIP, WAS TOLD THE TRANSMISSION HAD FAILED & WOULD HAVE TO BE REPLACED. ISSUES CAUSED FROM FAULTY RADIATOR DRAINAGE INTO TRANSMISSION FLUID. I HAVE READ OF COUNTLESS OTHER REPORTS OF THIS SAME ISSUE. THIS YEAR VEHICLE SHOULD BE RECALLED BY DEALERSHIP TO CORRECT THIS RECURRING PROBLEM. IT WONT BE LONG BEFORE SOMEONE LOSES CONTROL OF THEIR VEHICLE DUE TO FAILED TRANSMISSION & HITS ANOTHER VEHICLE OR KILLS SOMEONE! *TR

FINALLY MANAGED TO GET IT TO A DEALERSHIP WHERE THEY TOLD ME IT WAS THE TRANSMISSION FLUID MIXING WITH THE RADIATOR FLUID. TOLD ME I NEEDED BOTH REPLACED AND QUOTED OVER $6500 FOR THE FIX. CHECK ENGINE LIGHT WAS ON AT THE TIME, BUT I WAS ALSO HAVING A PROBLEM WITH THE FUEL GAUGE (ALSO ANOTHER KNOWN PROBLEM IN XTERRAS). *TR

UPON TAKING IT TO MY MECHANIC I WAS TOLD THAT THERE WAS A LEAK BETWEEN THE TRANSMISSION AND ENGINE COOLANT SYSTEMS. THE FIX WOULD REQUIRE A REPLACEMENT OF BOTH SYSTEMS TOTALLY APPROX. $6000! APPARENTLY THIS IS A "KNOWN ISSUE" WITH 2005-2010 XTERRAS. UPON CONTACTING NISSAN I WAS TOLD THAT SINCE MY VEHICLE WAS OVER 100,000 MILES THAT THERE WAS NOTHING THAT THEY COULD DO FOR ME. IF THIS IS A KNOWN ISSUE, AND A RATHER MAJOR ONE AT THAT, I'M NOT SURE WHY THERE HASN'T BEEN ANY RECALLS OR SOME KIND OF FIX. *TR

I HAD A COMPLETE LOSS OF MOTIVE POWER AND NEEDING TO BE TOWED TO A SHOP. THE SHOP DIAGNOSED THE PROBLEM AS A FAILED TRANSMISSION FLUID COOLER LOCATED IN THE RADIATOR ASSEMBLY THAT ALLOWED COOLANT TO MIX WITH AND CONTAMINATE THE AUTOMATIC TRANSMISSION FLUID, RESULTING IN DAMAGED INTERNAL TRANSMISSION COMPONENTS AND A DAMAGED INTERNAL TRANSMISSION COMPUTER. THERE WERE NO WARNING SIGNS LEADING UP TO OR JUST PRIOR TO THE FAILURES. THE TRANSMISSION AND RADIATOR NOW NEED TO BE REPLACED. *TR

AFTER 3 MONTHS OF REPLACING ELECTRICAL WIRING FROM FRYING NARROWED DOWN TO RADIATOR AND TRANSMISSION (FUSE THAT BLEW) THE COOLANT HAD BACKED UP AND TORE UP TRANSMISSION. IF IT HAD BEEN ON THE ROAD THERE WOULD HAVE BEEN A FULL BLOWN FIRE ON A HIGHWAY WITH POSSIBILITY OF HUMAN DAMAGES. *TR

WHILE TURNING BACK INTO TRAFFIC MY 2005 NISSAN XTERRA JERKED AS I BEGAN TO ACCELERATE OVER 20 MPH. ONCE I GOT THE VEHICLE TO THE SPEED OF TRAFFIC IT BEGAN TO HAVE TROUBLES SHIFTING GEARS AND ACCELERATING. WHILE THE VEHICLE WAS AT A STEADY SPEED I DIDN'T NOTICE ANY OTHER ISSUES. AS I SLOWED TO AN EXIT THE VEHICLE STARTED TO JERK AND NOT SHIFT PROPERLY. IT ALSO HAD TROUBLE ACCELERATING. AFTER HAVING THESE ISSUES I CHECKED MY FLUIDS AND FOUND A MILKY LIKE SUBSTANCE WAS IN MY TRANSMISSION AND MY COOLANT. I RESEARCHED THE PROBLEMS I WAS HAVING WITH MY XTERRA AND FOUND THAT IT WAS VERY COMMON AND REALIZED THAT THEIR IS A CRACK IN MY RADIATOR WHICH IS CAUSING THE CONTAMINATION OF MY TRANSMISSION AND COOLANT. I HAVE HAD THIS VEHICLE FOR JUST ABOUT TWO MONTHS AND IT IS VERY UPSETTING TO KNOW THAT I MAY HAVE TO PAY FOR A NEW TRANSMISSION AND RADIATOR WHICH IS MORE THEN WHAT I PAID FOR THE VEHICLE. *TR

DRIVING XTERRA ON HIGHWAY WHEN SUV STARTED TO HESITATE WHEN MOVING FORWARD IN TRAFFIC....SUV WOULD HESITATE, REV...AND NOT SHIFT OUT OF GEAR EASILY UPON ACCELERATION. TOOK SUV TO MECHANIC AND FOUND OUT THE RADIATORS ENGINE COOLANT WAS LEAKING INTO THE TRANSMISSION FLUID CAUSING THE PROBLEM. I LUCKED OUT AND DID NOT DAMAGE THE TRANSMISSION, HOWEVER; I AM HAVING TO REPLACE THE RADIATOR DUE TO THE NISSAN KNOWN DEFECT. I WAS NEVER GIVEN ANY LETTERS OR NOTIFIED ABOUT THIS MECHANICAL PROBLEM AND NOW WILL BE PAYING UNDER A $900 FOR FLUID FLUSH, NEW RADIATOR AND NEW FLUIDS. THIS IS NOT OK FOR NISSAN TO NOT NOTIFY THE VEHICLE OWNERS!!!! I EXPECT REPAYMENT FROM NISSAN ON THEIR FAULTY MECHANICAL EQUIPMENT. *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.
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.
