NISSAN WILL NOT STEP UP AND FIX THEIR MISTAKE, OUR CAR IS AT 87000 MILES AND THE COOLANT IS LEAKING INTO THE TRANSMISSION DUE TO HOW NISSAN CONFIGURED THEIR SYSTEM FROM THE YEARS OF 2006 - 2009. WHEN I SPOKE WITH [XXX] AT NISSAN CONSUMER AFFAIRS HE INTIMATED THAT NISSAN IS NOT AWARE OF THIS BEING A MAJOR ISSUE, BUT INTERESTINGLY ENOUGH STOPPED USING THIS CONFIGURATION IN 2010. THEY CLAIM THAT IT WILL NOT HAPPEN TO EVERY NISSAN, WE NEED MORE CONSUMERS TO COME FORWARD, SO THAT THIS WILL BECOME A "RECALL". THE SYSTEM IS FAULTY IT MAY NOT HAPPEN AT 80,000 / 90,000 / 100,000 , BUT COUNT ON IT HAPPENING AT SOME POINT. THIS IS A VERY EXPENSIVE REPAIR. IF NISSAN HAD COMMUNICATED TO US THAT THE WARRANTY COVERING THIS TRANSMISSION FAILURE WAS EXTENDED TO 80,000 BUT OF COURSE WHY WOULD THEY ADMIT TO A FAULTY SYSTEM, AND LET THEIR VALUED CUSTOMERS KNOW. SIMPLE THEY DO NOT VALUE THEIR CUSTOMERS, THEY LOST THIS GROUP. WAY TO GO NISSAN, SOMEWHERE DOWN THE LINE THIS WILL HURT YOU.

STARTED OVER A YEAR AGO THAT WHILE DRIVING THE MOTOR WOULD JUST STOP RUNNING, WOULD HAVE TO COAST TO THE SIDE IF THE ROAD WITHOUT POWER STEERING OR BRAKES. I TOOK IT INTO THE SHOP AND THEY COULDN'T FIND OUT THE PROBLEM. NOW THAT MY TRANSMISSION IS STARTING TO SHAKE AND MAKE NOISE, I TOOK IT TO THE DEALER. THEY TOLD ME THAT MY RADIATOR IS MAKING INTO THE TRANSMISSION AND THAT MAKES THE MOTOR QUIT AND LOSS OF POWER. I AM INFORMED THAT I NEED A NEW RADIATOR AND TRANSMISSION. LOOKING ONLINE I SEE THAT THERE ARE A LOT OF PEOPLE WITH THIS SANE SAFETY ISSUE AND THAT THERE IS NO RECALL. I THINK THAT THERE SHOULD BE A RECALL BECAUSE IT'S SAFETY ALONE! I ALMOST HIT A CAR AND A PEDESTRIAN WHILE TRYING TO STEER OFF THE ROAD AND STOP. PLEASE HELP WITH A RECALL!!

I HAVE A 2006 NISSAN SE XTERRA 4.0 4X2 AUTOMATIC -I STARTED NOTICING WHEN GETS SPEED UP TO 45 MILES IT IS MAKING A HARD SHIFTING AND WHEN SLOWING DOWN MAKING A HARD DOWN SHIFTING AS WELL. I MOSTLY NOTICE THIS WHEN THE VEHICLE IS ALREADY WARMED UP AND STOP AND GO TRAFFIC IS WHEN IT STARTS ACTING UP, LIKE A CLUNK NOISE AND FEEL LIKE IT IS LOOSING POWER IN THE TRANSMISSION. IT WAS A COLD DAY AND WHEN LEAVING WORK AND I BACKED UP AND THEN PUT IN DRIVE AND STARTED TO MOVE FORWARD ALL OF A SUDDEN THE SERVICE ENGINE LIGHT CAME ON AND IT FELT LIKE I HAD LOST POWER TO THE TRANSMISSION. (BOGGED DOWN FEELING) I HAD TO PRESS FURTHER DOWN ON THE PEDDLE TO GET THE XTERRA TO DRIVE. I DROVE HOME SLOWLY WITH MY FLASHERS ON PRAYING TO GOD I WOULD NOT BREAK DOWN WITHIN THE 7MILES. THE NEXT DAY I DROVE 2 MILES TO ORIELLYS TO PULL THE CODE P1754 WITH SEVERAL OTHERS.I DROVE TO A TRANSMISSION SHOP AND WAS GIVEN A "WORSE CASE SCENARIO" CHARGE OF ABOUT $3300.00 -I STILL OWE $6000.00 FOR IT! I STARTED TO INVESTIGATE THE ISSUE ONLINE WITH ALL OF THE FORUMS/PARTS/REBUILDS AND SUCH AND FOUND THAT THE TRANSMISSION IS THE ISSUE WITH THE COOLANT LINE IN RADIATOR CRACKING AND LEAKING ATF INTO TRANSMISSION CAUSING PROBLEMS WITH CORROSION IN THE VALVE BODY AND TRANSMISSION (O RINGS/SEALS) CAUSING TO BE REPLACED WHICH IS (FAULTY ENGINEERED/MANUFACTURED HIGHLY EXPENSIVE DEFECT) AT AROUND 100,000 MILES AND COST IS $1100.00 FOR BODY VALVE, REBUILDING TRANSMISSION ($2800.00-($5000.00 FOR NEW) AND REPLACING THE RADIATOR $ 260.00 AND LETS NOT FORGET ABOUT THE LABOR AT ABOUT $110.00 AN HOUR FOR AROUND 13 HOURS. WHO HAS THIS KIND OF MONEY FOR THIS REPAIR?? I LOVE MY XTERRA BUT NOT AT THIS COST SINCE I FOUND OUT THAT EVERY 100,000 I WILL HAVE TO REPLACE THE $1100.00 TRANSMISSION VALVE BODY (SOLENOIDS FAILING)!! I AM VERY DISAPPOINTED WITH NISSAN. *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.

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.
