UPON TURNING A CORNER AFTER COMING TO A COMPLETE STOP AT A STOP SIGN IN MY NEIGHBORHOOD, I WENT TO ACCELERATE AND MATCH THE SPEED OF ONCOMING TRAFFIC. THE GEAR FAILED TO SHIFT APPROPRIATELY (TRANSMISSION) AND GIVING THE CAR GAS SIMPLY REVVED THE ENGINE. LUCKILY THE APPROACHING CAR RESPONDED WELL AND SLOWED TO AVOID A REAR COLLISION WHILE I EASED OFF THE PEDAL AND THEN GENTLY ACCELERATED AGAIN TO MY LOCAL MECHANIC. UPON HIS EXAMINATION OF MY 2006 XTERRA, HE DETERMINED THAT THE TRANSMISSION FLUID AND COOLANT WERE MIXING AND DESTROYING BOTH MY RADIATOR AND TRANSMISSION. A QUICK SEARCH ON THE INTERNET REVEALED THAT THIS DANGEROUS PROBLEM IS COMMON AMONG NISSAN OWNERS! WHEN I PURCHASED THE VEHICLE FROM SMITHTOWN NISSAN IN 2010 AND SUBSEQUENTLY, THERE WAS ABSOLUTELY NO NOTIFICATION OR RECALL REGARDING THIS DANGEROUS HAZARD. THIS IS UNACCEPTABLE AND LIFE-THREATENING. THERE SETTLEMENT OF A CLASS ACTION LAWSUIT IS INSUFFICIENT (A $2500 - $3K) CO-PAY TO REPLACE THE TRANSMISSION AND POTENTIALLY HAVE THE SAME DEFECT AGAIN! MY WIFE AND KIDS RELY ON MY CAR EVERY DAY AND I FEEL FORTUNATE THAT I DID NOT WAIT ANY LONGER TO HAVE THE CAR EXAMINED, BUT I AM EXTREMELY DISTURBED BY NISSAN'S NEGLIGENCE. *TR

THE INITIAL INCIDENT WAS FAILED TIMING CHAIN TENSIONER GUIDES. AS INDICATED EARLIER NISSAN KNOWINGLY REDESIGNED THE PARTS SINCE THE ORIGINALS WERE FOUND TO WEAR THROUGH, CAUSING THE TIMING CHAIN TO RUB DIRECTLY ON THE METAL POST OF THE TENSIONER AND CONTACT THE HOUSING COVER. DURING THE REPAIR THE NISSAN SERVICE DEPARTMENT CONFIRMED THE FAILED RADIATOR COOLANT CONTAMINATION ADDRESSED IN ODI NHTSA ACTION NUMBER: DP12004. THE TIMING CHAIN AND GUIDES WERE REPLACED; THE RADIATOR WAS REPLACED; COOLANT WAS FLUSHED; TRANSMISSION WAS DRAINED, FLUSHED, AND FILLED. THE SERVICE DEPARTMENT ALSO CONFIRMED NISSAN, N.A. WOULD NOT OFFER ANY AMOUNT OF REPAIR ASSISTANCE. TOTAL COST WAS $2200. THE DAY AFTER THE VEHICLE WAS REPAIRED IT SUDDENLY DECELERATED FROM 55MPH TO 30MPH AND THE RPM'S INCREASED TO 4K+ WHILE TRAVELING ON A MULTI LANE DARK COUNTRY HIGHWAY AT 11PM. THE SECTION OF HIGHWAY DID NOT HAVE AN EMERGENCY LANE OR SHOULDER. A VEHICLE WAS IN THE LEFT LANE AND A SEMI-TRUCK WAS QUICKLY APPROACHING FROM THE REAR IN THE RIGHT LANE. ONCE CROSSING THE BRIDGE THE VEHICLE WAS JERKED TO THE SHOULDER, AVOIDING A REAR COLLISION FROM THE APPROACHING SEMI-TRUCK. THE VEHICLE WAS TURNED OFF AND RESTARTED. THE RPM'S RETURNED TO 1K, THE TRANSMISSION WAS IN NEUTRAL, AND THE CHECK ENGINE WAS ILLUMINATED. THE FOLLOWING DAY NISSAN SERVICE CONFIRMED IT WAS A FAILING VALVE BODY AS A RESULT OF THE COOLANT CONTAMINATION. THE WHOLESALE REPAIR COST WAS QUOTED AT $1400. AGAIN, NISSAN, N.A. WOULD NOT ADDRESS THE FAILURE. AT THIS TIME THE REPAIR HAS NOT, AND WILL NOT, BE COMPLETED. *JS

REAR PASSENGER DOORS KEEP LOCKING AND WON'T OPEN/UNLOCK AT ALL. OEM PARTS WERE USED FOR ACTUATOR AND OTHER ISSUES, HOWEVER IT HAS HAPPENED AGAIN. VERY UNSAFE, AS IF THEY JAM, WE CAN'T EXIT THE VEHICLE AND HAVE TO CLIMB TO THE REAR HATCH OR THROUGH THE FRONT SEATS. IF THERE WERE AN ACCIDENT, IT WOULD BE DETRIMENTAL. *TR

THE RADIATOR COOLING WATER GOT INTO THE TRANSMISSION FLUID. THIS CAUSED STRONG VIBRATION THAT WE HAD TO GET OFF THE ROAD IN THE MIDDLE OF A HIGHWAY. THE DAMAGE WAS REQUIRED TO REPLACE THE RADIATOR AND FLUSH THE TRANSMISSION . IT STARTED OTHER PROBLEMS WITH THE TRANSMISSION SAFETY SWITCH THAT CAUSED ENGINE TROUBLE ALERT. AFTER FEW WEEKS THE CAR STALLED ALTOGETHER AND WE NOW HAD TO TOW IT TO A GARAGE. THIS IS A PROBLEM THAT WAS REPORTED BEFORE AND I DO NOT UNDERSTAND WHY NISSAN DOES NOT FIX THE PROBLEM AND REPAIR THE DAMAGED UNITS. *TR

BEGAN HEARING A WHINING NOISE FROM ENGINE, INCREASING WITH RPM. TOOK TO DEALERSHIP, WHO INDICATED IT WAS BAD TIMING CHAIN TENSIONER SHOES/GUIDES. SERVICE ADVISOR INDICATED THIS IS A VERY COMMON ISSUE, AND NISSAN REDESIGNED THE PARTS SINCE THE ORIGINALS WERE FOUND TO WEAR THROUGH, ALLOWING THE TIMING CHAIN TO RUB DIRECTLY ON THE METAL POST OF THE TENSIONER. THE TIMING CHAIN SYSTEM SHOULD LAST FOR THE LIFE OF THE ENGINE, NOT REQUIRE A $1700 REPAIR ONLY ABOUT HALFWAY THROUGH THE ENGINE LIFE. THIS IS ALSO A VERY UNSAFE SITUATION, SINCE A TIMING CHAIN FAILURE COULD QUICKLY DESTROY THE ENGINE, LEAVING THE CAR WITHOUT ENGINE POWER OUT ON THE ROAD. THIS SHOULD BE A RECALL. *TR

TURNED ONTO A SMALLER COUNTRY ROAD, COULD NOT ACCELERATE MORE THAN 20 MPH, AND SLOWLY DESCENDED FROM THERE UNTIL FINALLY COMING TO A COMPLETE STOP.

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.

Consequence & remedy

Consequence: THIS COULD CAUSE THE VEHICLE TO RUN OUT OF GAS AND STALL IN TRAFFIC, INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPLACE THE FUEL LEVEL SENDING UNIT INSIDE THE FUEL TANK WITH A NEW ONE THAT HAS A MODIFIED FLOAT ARM. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR BEFORE MARCH 22, 2010. 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.
