MY NISSAN XTERRA STARTED MAKING A VIBRATION SOUND AROUND AUGUST OF 2011. IT SOUNDED LIKE YOUR VEHICLE WAS RUNNING OVER A "RUMBLE STRIP". IT WAS INFREQUENT AT FIRST SO I IGNORED IT. I DID NOTICE SOME OTHER WARNING SIGNS OF POTENTIAL TROUBLE (AT HINDSIGHT). THE VEHICLES HEATER WOULD NEVER HEAT THE INTERIOR OF THE VEHICLE AT IDLE, BUT WOULD DO IT AT SPEED. NISSAN KNOWS THE ISSUE IS A DEFECT BUT REFUSES TO TAKE RESPONSIBILITY. SEVERAL TIMES WHILE I HAVE BEEN DRIVING THE VEHICLE IT WOULD SHUDDER AND ALMOST RESULT IN A ACCIDENT. I HAVE ONLY NARROWLY AVOIDED A COLLISION ON 3 SEPARATE OCCASIONS. NISSAN EXTENDED THE POWERTRAIN WARRANTY TO 80,000 MILES BECAUSE THEY KNOW OF THE ISSUE, BUT REFUSE TO ADMIT ITS A DEFECT. HAD I BEEN INFORMED ABOUT THE WARRANTY EXTENSION I MAY HAVE BEEN ABLE TO HAVE IT SERVICES WHILE WITHIN THE WARRANTY PERIOD. MY VEHICLE IS CURRENTLY AT 83,000 MILES, BUT WITHIN THE 96 MONTH PORTION OF THE WARRANTY. I'M CURRENTLY AFRAID TO DRIVE THE VEHICLE ON THE HIGHWAY BECAUSE I'M WORRIED THE TRANSMISSION WILL FAIL AT HIGH SPEED AND RESULT IN A SERIOUS ACCIDENT. *TR

IT HAS COME TO MY ATTENTION DURING A RECENT HORRIFIC EVENT THAT MY TRANSMISSION HAS SEIZED DUE TO A FAILURE OF THE RADIATOR CRACKING AND MIXING COOLANT INTO THE TRANSMISSION. I HAD BOUGHT AN EXTENDED WARRANTY PLAN THROUGH MY DEALER WHEN I PURCHASED THIS VEHICLE IN 2009. THEY HAD AN ADJUSTOR FROM CAREFREE CAR PROTECTION COME OUT TO LOOK AT THE VEHICLE ON FRIDAY NOVEMBER 11, 2011. WITH THAT BEING SAID; THEY STATED THEY DO NOT COVER THE RADIATOR ISSUE; AND SINCE IT WAS THE FAULTY RADIATOR THAT CAUSED THE ENTIRE TRANSMISSION TO FAIL AND ULTIMATELY SEIZED, THEY WILL ALSO NOT COVER THAT OR ANY OTHER OF THE REPAIRS. UPON A BIT OF RESEARCH ON MY OWN THIS IS A KNOWN FAILURE WITH THIS PARTICULAR YEAR/MAKE/MODEL OF NISSAN. THERE ARE HUNDREDS IF NOT THOUSANDS OF DOCUMENTED CASES OF CONSUMERS WITH THE VERY SAME ISSUE. THERE HAS BEEN NO RECALL MADE ON THIS AT ALL. YES, NISSAN EXTENDED THE RADIATOR WARRANTY UP TO 80,000 MILES BUT NOT THE TRANSMISSION. GUESS WHAT; THIS HAPPENED IN MY VEHICLE AT 89,000, SO NOT ONLY CAN I NOT FIX THE RADIATOR ISSUE BUT THE TRANSMISSION IS ALSO THE SAME. THE WORST PART OF ALL THIS IS; ON WEDNESDAY NOVEMBER 9TH MY FOUR YEAR OLD DAUGHTER AND I WERE ALMOST KILLED DUE TO THIS KNOWN MALFUNCTION. WE WERE TRAVELING ON A VERY BUSY HIGHWAY IN MID-DAY TRAFFIC WHEN THE ENTIRE TRANSMISSION SEIZED IN THE MIDDLE OF THE HIGHWAY. I HAVE TO SAY, IF IT WERE NOT FOR MY EXTENSIVE TRAINING IN EMERGENCY VEHICLE OPERATIONS BY THE STATE OF MASSACHUSETTS , I HONESTLY DO NOT BELIEVE MY DAUGHTER OR I WOULD BE ALIVE TODAY. THE VEHICLE SEIZED RIGHT ON THAT STRETCH OF HIGHWAY AND I HAD TO VEER INTO A DITCH AVOIDING OTHER VEHICLES, TREES, GUARDRAILS AND JERSEY BARRIERS. I AM THANKFUL THAT WE DID SURVIVE THAT HORRIFIC EVEN. NOW I AM LOOKING TO NISSAN TO DO THE RIGHT THING AND MAKE THIS RIGHT. UPDATED IVOQ 12/01/11 *TR

RECENTLY I EXPERIENCED A SUDDEN LOSS OF ACCELERATION AS I ATTEMPTED TO MERGE ONTO A HIGHWAY. I WAS ALSO VERY LUCKY THAT I DIDN'T CAUSE A SERIOUS ACCIDENT. THE PROBLEM WAS INTERMITTENT AT FIRST AND THEN INCREASED. NISSAN ACKNOWLEDGED A RADIATOR DESIGN FLAW AND EXTENDED THE BASIC WARRANTY TO LESSOR OF 96 MONTHS OR 80K MILES. I CONTACTED NISSAN CONSUMER AFFAIRS TO INFORM THEM MY XTERRA WAS AFFECTED BY THE SAME PROBLEM. WHILE UNDER 96 MOS, MY VEHICLE HAS 89K MILES. I REQUESTED AN EXCEPTION WHICH WAS DENIED. NISSAN'S FAILURE TO STAND BEHIND THEIR PRODUCTS, PARTICULARLY WHEN THE PROBLEM REPRESENTS A SERIOUS SAFETY CONCERN AND ATTRIBUTABLE TO A DESIGN FLAW, IS INEXCUSABLE. NISSAN DENIES ANY SAFETY CONCERN. THIS PROBLEM (REFERENCED BY NISSAN IN THE RADIATOR ASSEMBLY CUSTOMER SATISFACTION PROGRAM DESCRIPTION) PERTAINS TO 2005-2010 XTERRA, PATHFINDER AND FRONTIER VEHICLES EQUIPPED WITH AUTO TRANSMISSIONS. CORROSION WITHIN THE RADIATOR LEADS TO A CRACK AND CONTAMINATION OF ENGINE COOLANT WITH TRANS FLUID, DAMAGING RADIATOR & TRANSMISSION CORROSION DEVELOPS OVER TIME AND MOST VEHICLE OWNERS WILL LIKELY EXCEED THE 80K LIMIT BEFORE PROBLEM PRESENTS ITSELF. AN INTERNET SEARCH REVEALED 15 DEDICATED WEB THREADS TO THIS PROBLEM AND THEY ARE MOSTLY 2005 VEHICLES. IF NISSAN DIDN?T CORRECT THE DESIGN FLAW BEFORE 2010, THE # OF FAILURES WILL SIGNIFICANTLY INCREASE OVER THE COMING YEARS AS MODEL YR 2005-2010 CARS AGE. HOW MANY ACCIDENTS OR FATALITIES NEED TO OCCUR DURING THIS PERIOD BEFORE NISSAN IS HELD ACCOUNTABLE FOR THEIR NEGLIGENCE? THE DEALER ESTIMATE TO REPAIR MY XTERRA IS $6,760. THIS IS A SIGNIFICANT FINANCIAL BURDEN AND HARDSHIP ON ANY VEHICLE WITH JUST OVER 80,000 MILES. HOW MANY NISSAN OWNERS HAVE TO EXPERIENCE FINANCIAL HARDSHIP BEFORE NISSAN IS HELD ACCOUNTABLE?? *TR

I WAS DRIVING MY 2005 NISSAN XTERRA AT 55 MPH ON A TWO LANE HIGHWAY WHEN IT BEGAN TO SHAKE VIOLENTLY AS IF I HAD RAN OVER SPILLED LUMBER OR RUMBLE STRIPS. I BRAKED HARD AS I THOUGHT I HAD RAN OVER SOMETHING. I HADN'T, SO AFTER PULLING OVER AND CHECKING FOR LOOSE TIRES OR DRIVELINE I CONTINUE ON PERPLEXED AS TO WHAT HAPPENED. A FEW MILES LATER IT DID IT AGAIN. COME TO FIND OUT THERE IS A KNOWN DEFECT ON 2005 THRU 2010 NISSAN XTERRA'S, PATHFINDERS, AND FRONTIER'S IN WHICH THE RADIATORS INTERNALLY LEAK WATER INTO THE AUTOMATIC TRANSMISSIONS AND CAUSES THE VIOLENT SHAKING AT HIGH SPEEDS. NISSAN IS AWARE OF THE ISSUE AND HAS ONLY CHOSEN TO EXTEND THE WARRANTY ON THE RADIATORS AND NOT RECALL THE VEHICLES. IN FACT THE LETTER SENT TO THE CONSUMERS DOESN'T EVEN REFERENCE THE TRANSMISSION (IN WHICH IT DESTROYS). WHILE MY FAMILY AND I WERE NOT HURT, IT WAS A CLOSE CALL AND COULD HAVE EASILY BEEN WORSE AT THE SPEED I WAS GOING AND THE EFFECT THE FAILURE HAS ON THE VEHICLE. *TR

I WAS PICKING UP MY CHILDREN FROM SCHOOL AND MY CAR JUST STOPPED DRIVING IN THE MIDDLE OF THE INTERSECTION WHILE I WAS MAKING A LEFT TURN AT A STOPLIGHT. I BROUGHT IT TO A TRANS SHOP AND THEY SAID I HAVE COOLANT IN MY TRANSMISSION WHICH CAUSED IT TO FAIL. REPAIRS ARE ESTIMATED AT $4326 AND I AM JUST ANGRY AND SICK OVER THIS SITUATION. NOT ONLY WAS IT A SCARY SITUATION TO BREAK DOWN IN THE MIDDLE OF THE INTERSECTION WITH MY KIDS IN THE CAR BUT I AM VERY DISAPPOINTED IN ALL THE REPORTS I HAVE BEEN READING ABOUT IN THE 2005 XTERRA. I CAN NOT AFFORD TO FIX THIS PROBLEM AND THIS IS SIMPLY NOT FAIR THAT NISSAN ISN'T TAKING RESPONSIBILITY FOR THEIR NEGLIGENCE. PLEASE HELP!! *TR

Oct 28, 2010

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.
