THERE WAS A LOUD RUMBLE AND JERKING WHILE DRIVING AT 35MPH. FLUID WAS LEAKING BADLY ALSO. I TOOK THE CAR TO NISSAN ON ON APRIL 21, 2008. THEY SAID THEY COULD NOT DUPLICATE THE PROBLEM. AGAIN, THE CAR STARTED JERKING AND MAKING LOUD RUMBLES. I TOOK IT BACK TO NISSAN AND THEY SAID THE U JOINTS WERE BAD AND REPLACED THEM. AS SOON AS I PULLED OUT OF THEIR PARKING AREA, THE CAR DID THE SAME THING. SO, I TOOK IT BACK AGAIN. THIS TIME, THEY TOLD ME THAT THE RADIATOR WAS COMING APART AND LEAKING ANTIFREEZE INTO TRANSMISSION. THEY CHARGED ME $1285.89 TO REPLACE THE RADIATOR AND FLUSH THE TRANSMISSION. IT IS NOW 2012 AND THE CAR IS DOING THE SAME THING AGAIN. THE PROBLEM WAS NEVER FIXED PROPERLY TO BEGIN WITH. I NEED A NEW TRANSMISSION AT A HIGH PRICE. ANYONE READING THIS SHOULD PHONE ME AT SO THAT WE CAN START A CLASS ACTION LAW SUIT AGAINST NISSAN. LETS INFORM EVERYONE WHO HAS HAD THIS PROBLEM. FROM WHAT I HAVE BEEN READING, THOUSANDS OF PEOPLE HAVE HAD THE SAME PROBLEM. THIS IS A SAFETY ISSUE AS WELL AS A COSTLY PROBLEM.

WHILE DRIVING, THE ENGINE CUTS OFF WITHOUT WARNING CAUSING ALL SYSTEMS TO SHUT DOWN, INCLUDING BRAKE ASSIST AND POWER STEERING CAUSING A NEAR COLLISION TWICE, ONCE WHILE NAVIGATING A CURVE AT LOW SPEED WITH A DITCH ON THE RIGHT SIDE AND ONCE WHILE NAVIGATING A CURVE AT HIGHER SPEED AND NEARLY COASTING INTO ONCOMING TRAFFIC. THE ISSUE IS DUE TO A KNOWN DEFECT IN THE RADIATOR CAUSING COOLANT TO SPILL INTO THE TRANSMISSION. THIS IS A MAJOR SAFETY CONCERN THAT APPEARS IN VEHICLES WITHOUT WARNING IN ANY CIRCUMSTANCE AT ANY SPEED. PLEASE INITIATE A RECALL ASAP FOR OUR SAFETY! *TR

MY HUSBAND AND I PURCHASED OUR 2005 NISSAN XTERRA, 17 MILES YOUNG. EXACTLY ONE MONTH AFTER WE PURCHASED, THE REAR DIFFERENTIAL WENT OUT AND WAS COVERED UNDER WARRANTY. NO PROBLEMS FOR A FEW YEARS, UNTIL WE NOTICED THAT THE GAS GAUGE WAS NOT GIVING ACCURATE READINGS, WE HAD TO WATCH OUR ODOMETER COUNT TO MAKE SURE WE DIDN'T RUN OUT OF GAS, WHICH IS A VERY SCARY THOUGHT WHEN YOU HAVE TWO YOUNG CHILDREN. THIS HAPPENED WHEN WE HAD APPROXIMATELY 80000 MILES ON THE TRUCK AND $600 TO REPAIR. SHORTLY AFTER, THE TRANSMISSION WAS ACTING UP AND THE HEATER WASN'T WORKING. NO WHY WASN'T THAT WORKING? APPARENTLY, NISSAN THOUGHT IT WOULD BE A COOL TRICK TO HAVE THE RADIATOR LEAK INTO THE TRANSMISSION.... BRILLIANT BUSINESS PLAN THEY HAVE. TOOK THE TRUCK IN AND HAD TO PAY $5800 TO HAVE THE TRANSMISSION, RADIATOR AND COMPUTER ALL REPLACED. THIS FINANCIAL HARDSHIP WAS IN FACT A HARDSHIP. ONE THAT SHOULDN'T HAVE HAD TO HAPPEN HAD NISSAN PROVIDED QUALITY PARTS AND PROVIDED STELLAR SERVICE. I WILL SUE NISSAN FOR THIS MAJOR SAFETY ISSUE, BLOG/FACEBOOK MY LITTLE HEART AWAY ABOUT HOW INSINCERE OF A COMPANY NISSAN IS AND NEVER EVER-EVER-EVER GIVE THEM A POSITIVE RECOMMENDATION. *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.

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

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.
