NISSAN NEEDS TO FORMALLY RECALL SEVERAL VEHICLES WITH RADIATOR/ TRANSMISSION PROBLEMS. IN MY CASE WHILE I WAS DRIVING MY VEHICLE SUDDENLY CAME TO A STOP WHILE I WAS ON THE ROAD DRIVING AT A SPEED OF 55 MPH. MY VEHICLE SHUT DOWN AND I TRIED TO TURN ON LUCKILY IT TURNED ON AND BEGAN TO RUN AGAIN. I PRESSED ON THE ACCELERATOR IT DID NOT RUN MORE THAN 20 MPH. I DECIDED TO TOW MY VEHICLE TO A LOCAL MECHANIC TO HAVE IT DIAGNOSED SINCE I WAS TERRIFIED OF IT SHUTTING DOWN ONCE AGAIN IN THE MIDDLE OF THE ROAD. MY MECHANIC DIAGNOSED MY VEHICLE AND CONCLUDED THAT FLUID FROM THE RADIATOR HAD LEAKED INTO THE TRANSMISSION. NONETHELESS, HE EXPRESSED TO ME THAT THIS WAS NOTHING NEW HE HAD SEEN WITH THESE VEHICLES. HE TOLD ME THAT HE HAD FIXED A COUPLE IN JUST THIS LAST YEAR. ACCORDING TO HIS PAST CLIENTS NISSAN FAILED TO DO ANYTHING TO CORRECT THE PROBLEM REGARDLESS OF THE POTENTIAL HAZARD. I VISITED THE DEALER IN WHICH I HAVE PURCHASED THE VEHICLE AND EXPLAIN THE SERVICE MAN MY CONCERN. HE CLEARLY TOLD ME THAT MY WARRANTY WAS OVER AND THAT THE LAWSUIT AGAINST NISSAN TO BE REIMBURSED HAD ENDED IN 2013. I TOLD HIM THAT MY VEHICLE FREQUENTLY COMES TO THEIR SERVICE CENTER FOR MAINTENANCE AND IF THEY WERE AWARE OF THE FAILURE IN THESES VEHICLES ONCE THEY REACH THEIR 100,000 MILES WHY DID THEY FAIL TO CORRECT THE PROBLEM BEFORE IT OCCURRED. IT SURPRISES ME THAT NISSAN FAILED TO INFORM ANY OF ITS CONSUMERS OF THE PROBLEM WHEN IT WAS GOING THROUGH A LAWSUIT. HE THEN PROCEEDED TO TELL ME THAT HE COULD NOT HELP ME AND REFERRED ME TO CORPORATE OFFICE. I WAS TOLD I WOULD BE CALLED WITHIN TWO DAYS. I RECEIVED THE CALL BACK FROM NISSAN SIMPLY TELLING ME MY CASE WAS REVIEWED AND THEY COULD NOT DO ANYTHING DUE TO THE FACT THAT MY WARRANTY IS OVER. NISSAN IS PUTTING THE LIVES OF THEIR CONSUMERS IN DANGER AND IS HIDING BEHIND THEIR WARRANTY GUIDELINES TO AVOID CORRECTING THEIR ENGINEERING ERRORS. *TR

RE: TRANSMISSION FLUID MIXED WITH RADIATOR FLUID CAUSING TRANSMISSION TO FAIL. HAD TO REBUILD TRANSMISSION. I RECEIVED NO NOTICE OF THE CLASS ACTION LAWSUIT RE: NISSAN TRANSMISSION/ RADIATOR LEAK ISSUES. IN SEPTEMBER OF 2014 MY TRANSMISSION STARTED TO FAIL. I HAD IT LOOKED AT BY TWO DIFFERENT SHOPS AND THEY ADVISED A RADIATOR AND TRANSMISSION REPLACEMENT. THIS COST ME: $5400 OUT OF POCKET. I NOW READ THAT NISSAN HAD A CLASS ACTION LAWSUIT AND WOULD COVER SOME CARS. MY CAR HOWEVER, IS OVER 100,000 MILES AND NISSAN IS NOT OFFERING ANY COMPENSATION. THIS IS TOTALLY UNACCEPTABLE AND I AM BEYOND FRUSTRATED WITH NISSAN. *TR

I TOOK MY PATHFINDER INTO A LOCAL SHOP BECAUSE I STARTED HEARING NOISE COMING FROM THE TRANSMISSION AT AROUND 45 MPH. I WAS INFORMED ANTIFREEZE GOT INTO MY TRANSMISSION FLUID DUE TO A RADIATOR FAILURE. THE SHOP REPLACED THE RADIATOR AND FLUSHED THE TRANNY. OVER A $600 BILL. THE SHOP HOPED IT WOULD FIX THE PROBLEM WITHOUT REBUILDING OR REPLACING THE TRANSMISSION. NO LUCK!! NOW I AM LOOKING AT ANOTHER $4000 PLUS ON SOMETHING THAT SHOULD NEVER HAVE HAPPENED. I WAS TOLD BY MANY SHOPS INCLUDING THE LOCAL DEALER THAT THIS IS A KNOWN PROBLEM. IF PROACTIVE BY THE MANUFACTURE COULD HAVE BEEN FIXED WITH REPLACEMENT OF THE RADIATOR. INSTEAD, NISSAN DECIDED TO EXTEND THE WARRANTY. NEVER INFORMING CUSTOMERS TO HAVE INSPECTED FOR PREMATURE FAILURE OF THE RADIATOR OR TRANNY. *TR

ME AND MY 6 MONTH OLD DAUGHTER WERE GOING DOWN THE ROAD WHEN MY CAR LOST ALL POWER AND WAS LIKE IT HAD BEEN SHIFTED INTO NEUTRAL.

AFTER OUR REPAIR GUY CHECKED ALL THE WIRING AND RAN TEST AND PULLED THE TRANSMISSION PAN OFF THE RADIATOR COOLANT HAD LEAKED INTO THE TRANSMISSION FULL RESULTING IN THE GEARS MESSING UP AND THE ENTIRE CAR UNDRIVEABLE. WE KNEW ABOUT THIS PROBLEM AND HAD CONTACTED NISSAN 6 MONTHS PRIOR TO CHECK THE RECALL AND WAS TOLD THIS VEHICLE HAD BEEN FIXED....OBVIOUSLY NOT. IF IT HAD BEEN FIXED IT WASN'T FIXED PROPERLY OR IT WOULD NOT HAVE FAILED AGAIN MANY TRIPS HAVE BEEN TAKEN SINCE THEN AND NOW WE ARE OVER 100,000 MILES AND IT'S A $3800 FIX BECAUSE NISSAN EITHER LIED AND IT WAS NEVER FIXED TO START WITH OR DIDN'T CORRECTLY FIX IT THE FIRST TIME. *TR
