VERIFIED AT LOCAL DEALERSHIP THAT RADIATOR COOLANT IS MIXING WITH TRANSMISSION FLUID WHICH CAUSES ROUGH SHIFTING AND CAR TO SHAKE AT CERTAIN SPEEDS. THIS IS A SERIOUS SAFETY ISSUE AS CAR CAN SUDDENLY LOSE POWER/BREAK DOWN WHILE DRIVING. RADIATOR AND TRANSMISSION NEED TO BE REPLACED. WE RECEIVED NISSAN'S EXTENDED WARRANTY (8 YR/80,000 MILES) ON RADIATOR LAST YEAR. CAR IS ONLY 800 MILES OUT OF WARRANTY, HOWEVER NISSAN WILL NOT COVER THE COST OF REPLACING THE RADIATOR AND TRANSMISSION. NISSAN NEEDS STAND BY ITS PRODUCT AND ISSUE A RECALL FOR THIS PROBLEM. *JS
I PURCHASED MY "CERTIFIED PRE-OWN" 2006 PATHFINDER WITH ONLY 37,000 MILES ON IT AND I PROPERLY MAINTAINED IT. DECEMBER 2010 I NOTICED THAT MY TRUCK WOULD LOSE POWER AND SPUTTER WHILE DRIVING AT A SPEED BETWEEN 40 TO 60 MPH, AND THAT IT WOULD ALSO "TREMBLE OR SHAKE" WHILE SHIFTING GEARS.

I PURCHASED MY "CERTIFIED PRE-OWN" 2006 PATHFINDER WITH ONLY 37,000 MILES ON IT AND I PROPERLY MAINTAINED IT. DECEMBER 2010 I NOTICED THAT MY TRUCK WOULD LOSE POWER AND SPUTTER WHILE DRIVING AT A SPEED BETWEEN 40 TO 60 MPH, AND THAT IT WOULD ALSO "TREMBLE OR SHAKE" WHILE SHIFTING GEARS. I TOOK MY TRUCK TO THE DEALER TO HAVE IT SERVICED AND TUNED UP. I WAS INFORMED THAT THE RADIATOR WAS LEAKING INTO THE TRANSMISSION AND THAT I NEEDED TO HAVE BOTH REPLACED. I COULDN'T SEE STRAIGHT! I ASKED THE SERVICE TECH WHY IN THE HELL I WOULD NEED A NEW TRANSMISSION ON A VEHICLE WITH JUST OVER 100,000 MILES AND THAT I'M STILL PAYING FOR NO LESS. THE TECH SUGGESTED THAT THE TRANSMISSION COULD BE "SAVED" AND I WOULD STILL HAVE TO BUY A NEW RADIATOR AND OTHER PARTS. A YEAR LATER- 03/12 MY TRUCK IS BEHAVING THE SAME WAY SO INSTEAD OF RETURNING TO THE DEALER I DECIDED TO TAKE IT TO A TRANSMISSION SPECIALIST. WHEN I INFORMED HIM OF MY PROBLEM HE ASKED IF I HAD ANY PROBLEMS WITH THE RADIATOR, AS A MATTER A FACT I TOLD HIM I HAD IT REPLACED A YEAR AGO BECAUSE IT WAS LEAKING INTO THE TRANSMISSION. HE INFORMED ME THAT HE'S HAD A NUMBER OF PATHFINDER OWNERS COMING TO HIS SHOP ABOUT THIS VERY PROBLEM, AND INFORMED ME THAT THERE WAS A CLASS ACTION LAWSUIT AGAINST NISSAN. I FOUND THE LAWSUIT ON THE WEB AGAINST NISSAN AND SINCE CONTACTED THE ATTORNEY AND JOINED IN THE LAW SUIT. UP UNTIL THE MOMENT I HAD THIS PROBLEM I WAS A LOYAL NISSAN OWNER, EVEN BACK TO THE DAYS WHEN MY FATHER OWNED A DATSUN AND IT BECAME MY FIRST CAR. IT'S ONE THING TO REPLACE A TRANSMISSION SIMPLY DUE TO NORMAL WEAR, IT'S ANOTHER TO HAVE CONSUMERS DO SO BECAUSE OF FAULTY DESIGN FROM THE DEALER. I'M DISAPPOINTED THAT NISSAN WOULD TREAT AND HANDLE THEIR CUSTOMERS THIS WAY. *JS
RADIATOR IS LEAKING COOLANT INTO THE TRANSMISSION, MECHANIC EXPLAIN THAT IT WOULD COST $5500.00 TO FIX AND THIS SHOULD NOT HAPPEN, IS A MANUFACTURE DEFAULT. PLEASE HELP. THANK YOU. *TR

I WAS TOLD THIS IS A COMMON ISSUE WITH NISSANS AND THEY ARE NOT RECALLING THE PROBLEM. THEY EXTENDED THE WARRANTY TO 80,000 MILES; UNFORTUNATELY, I HAVE 95,000 MILES ON MY TRUCK. IT WOULD HAVE COST ME APPROXIMATELY $1,000 TO FIX THE RADIATOR, MORE THAN 5000 TO FIX THE TRANSMISSION. *TR

TL* THE CONTACT OWNS A 2006 NISSAN PATHFINDER. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 70 MPH, THE VEHICLE WAS RESISTANT TO ACCELERATION. THE VEHICLE WAS TOWED TO THE DEALER WHERE THEY ADVISED THE CONTACT THAT COOLANT LEAKED INTO TRANSMISSION AND THE FLUID FROM THE TRANSMISSION LEAKED INTO THE RADIATOR. THE RADIATOR AND THE TRANSMISSION WOULD BOTH NEED REPLACING. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND THEY OFFERED NO ASSISTANCE. THE FAILURE AND THE CURRENT MILEAGES WERE APPROXIMATELY 92,200. UPDATED 04/27/12*LJ
THE RADIATOR COLLING PUMP CRACKED CAUSING THE COOLING FLUID TO LEAK INTO THE TRANSMISSION AND MIX WITH THE TRANSMISSSION FLUID IN RETURN A NEW RADIATOR DRIVE UNIT AND TRANSMISSION NEEDED TO BE REPLACED AS WELL AS THE TORQUE CONVERTER. *TR

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.
