TOOK CAR TO TRANSMISSION SHOP AND THE MECHANIC ADVISED ME THAT THE ENTIRE TRANSMISSION WAS RUINED DUE TO RADIATOR COOLANT BEING LEAKED INTO THE TRANSMISSION. PRIOR TO THIS I HAD THE RADIATOR INSPECTED ON SEVERAL OCCASIONS IN THE LAST COUPLE OF YEARS SINCE THE EXTENDED WARRANTY HAD BEEN PLACED ON THE VEHICLE AND I HAD ALREADY SURPASSED THE MILEAGE OF THE WARRANTY. THE RADIATOR SHOWED NO SIGNS OF WEAR AND TEAR. *TR

I HAVE 3 CHILDREN AGES 7 WEEKS TO 5 YRS AND COUNT MY SELF LUCKY THAT THE PROBLEM WAS DIAGNOSED BEFORE A POTENTIALLY LIFE THREATENING TRANSMISSION FAILURE ON BUSY LOS ANGELES COUNTY STREETS OR FREEWAYS. I WAS LATER APPALLED TO FIND OUT THAT NISSAN KNEW OF THE ISSUE, BUT COVERED IT UP AS EVIDENCED IN A NY TIMES ARTICLE DATED 8/24/2011. THE SERVICE ADVISOR AT THE DEALER INFORMED ME THAT MY CAR SITUATION WAS AN ISSUE THAT HE HAD SEEN BEFORE. I AM NOW BEING TOLD THAT IT WILL COST ME $4000 FOR MY CAR TO BE REPAIRED DUE TO A KNOWN DEFECTIVE RADIATOR THAT WOULD HAVE COST A FRACTION OF THAT TO REPLACE. I AM STILL WITHOUT A CAR AFTER 11 DAYS. *JS

MY 21 YEAR OLD DAUGHTER WAS DRIVING OUR XTERRA IN ELLENSBURG, WASHINGTON 260 MILES IN THE DESERT WHEN THE CAR TRANSMISSION STOPPED WORKING! BROUGHT IT FOR TWO RELIABLE ESTIMATES AND LIKE ALL THE OTHERS THIS IS A CAUSE FROM A DEFECT IN THE RADIATOR THAT OBVIOUSLY NISSAN HAS KNOWN ABOUT FOR QUITE A LONG TIME. DO THEY NEED MORE BAD PRESS? I WILL BE PUTTING IT ON CRAIGSLIST AND ANY PLACE ELSE I CAN TO INCLUDE THE BACK WINDOW OF THE TRUCK. MY DAUGHTER WAS STRANDED!!!! IN THE MIDDLE OF A DESERT WITH NO CELL PHONE RECEPTION. DOES NISSAN WANT THE LIABILITY OF THIS? IT'S THERES BECAUSE THEY KNEW ABOUT THE FAULTY POWER TRAIN AND DID NOTHING. I HAVE ADDED MY NAME AND FILED A CLASS ACTION LAW SUIT AGAINST NISSAN FOR THIS PROBLEM THAT THEY FAIL TO RECOGNIZE. I DON'T GET IT AT ALL. IT'S THE ERROR OF NISSAN AND THEY NEED TO TAKE RESPONSIBILITY FOR THEIR MESS! *TT

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
