I TOOK VERY GOOD CARE OF THIS CARE WITH OIL CHANGE, ALL FLUID CHANGES AS WELL. I CAN'T NOT AFFORD TO HAVE THIS PROBLEM FIXED. THE SUV HAS BEEN PARKED SINCE THEN AND THAT WAS OVER 3 YEARS AGO. I WAS HOPING TO HAVE A RESOLUTION OF THIS WITH A RECALL.

OUR CAR HAD NO PICKUP WHEN TAKING OFF FROM STOP LIGHT AND MAKING A LEFT TURN. WE WERE CROSSING TRAFFIC WHICH MADE THIS QUITE SCARY AS WE ALMOST STALLED IN THE MIDDLE OF THE ROAD. WE PULLED INTO A PARKING LOT AND TURNED IT OFF. WOULDN'T START BACK UP AND THE GEAR INDICATOR ON THE DASH WASN'T SHOWING WHICH GEAR IT WAS IN. HAD IT TOWED TO THE DEALERSHIP AND WAS TOLD THE COOLANT LEAKED INTO THE TRANSMISSION, WHICH IS A KNOWN PROBLEM WITH THIS CAR, AND CONTAMINATED THE TRANSMISSION AND THE SENSORS. I WAS NEVER CONTACTED ABOUT THIS ISSUE SO I DIDN'T KNOW ABOUT IT UNTIL I WENT ONLINE AND SAW ALL OF THE OTHER COMPLAINTS FROM PEOPLE WITH THE SAME ISSUE. I JUST WENT OVER THE 100,000 MILE MARK THIS YEAR SO NISSAN WILL NOT FIX IT. I DON'T UNDERSTAND WHY THIS ISN'T A RECALL ISSUE INSTEAD OF A WARRANTY EXTENSION ISSUE WITH NISSAN WILLING TO COVER THE COST OVER $3,000. WHO HAS $3,000 THAT THEY CAN AFFORD OR EVEN HAVE FOR THAT MATTER? I'VE FILED A COMPLAINT WITH NISSAN AND AM HOPING THAT SOMEONE WILL HELP ME EITHER PAY FOR THIS OR GIVE ME FULL FAIR MARKET VALUE FOR THE CAR SO I CAN BUY ANOTHER ONE AND USE THIS AS A TRADE IN. NOT SURE THAT I'LL BUY A NISSAN THOUGH, IF THEY DON'T TAKE CARE OF ME, THAT'S FOR SURE. THE OTHER ISSUES THAT I'VE HAD WITH THIS CAR IS THE FUEL SENSOR WENT OUT, WHICH I'VE ALSO SEEN OTHER COMPLAINTS ON AND THE WINDSHIELD WIPER MOTOR ON THE PASSENGER SIDE HAS GONE OUT. NOT SURE IF THIS HAS BEEN SOMETHING THAT OTHERS HAVE EXPERIENCED OR NOT. ALL IN ALL THIS HAS BEEN A GREAT CAR,BUT CONSIDERING I BOUGHT IT USED WITH VERY LOW MILES ON IT AND JUST MADE MY LAST CAR PAYMENT 4 DAYS AGO, I'M ABSOLUTELY SICK OVER THIS. EVEN WORSE IS THE FACT THAT WE COULD'VE BEEN KILLED BY ONCOMING TRAFFIC BUT WERE FORTUNATE ENOUGH THAT THE CAR DID MAKE IT BEFORE ANY CARS GOT TOO CLOSE TO US. IS THAT WHAT IT'S GOING TO TAKE BEFORE NISSAN DOES SOMETHING?

I TOOK IT TO THE MECANIC, HE FLUSHED THE RAIDIATOR AND FLUSH THE TRANSMISSION, BECAUSE THERE WAS A POSSIBILITY OF CROSS CONTAMINATIONS. THE VEHICULE WAS FINE FOR A COUPLE OF DAYS, FEW DAYS LATER MY CAR COMPLETELY SHUT DOWN ON NEW JERSEY TURNPIKE. I STRUGGLED TO PUT ON THE SIDE, THANX GOD NOBODY WAS HURT. TRANSMISSION GONE. I HAD TO TOW IT TO THE MECANIC AND I HAD TO SPENT 3K TO GET IT FIX. IT SEENS THAT IT IS A COMMON PROBLEM AND NISSAN SHOULD TAKE RESPONSABILITY FOR THIS CAR

WAS HAVING TROUBLE WITH TRANSMISSION ON 07 NISSAN XTERRA. FOUND A LAWSUIT THAT HAD BEEN SETTLED WITH NISSAN INVOLVING FACTORY DEFECTS OF THE RADIATOR OIL COOLER WHICH LEAKS INTO TRANSMISSION AND DESTROYS TRANSMISSION. TOOK AN OIL SAMPLE FROM MY VEHICLE TO AN INDEPENDENT COMPANY AND WAS TOLD THAT THEIR WAS ANTIFREEZE IN THE OIL. TOOK MY VEHICLE AND THE OIL SAMPLE INTO NISSAN SO THAT MY TRANSMISSION COULD BE REPLACED. ($2500 COST TO ME PER THE NISSAN LAWSUIT SETTLEMENT) SERVICE DEPARTMENT CALLED BACK AND TRIED TO TELL ME THAT WITHOUT DROPPING THE TRANSMISSION THAT THEY COULD TELL THAT THE ANTIFREEZE WAS NOT THE CAUSE OF MY FAILED TRANSMISSION. AFTER FURTHER DISCUSSION WITH THE SERVICE MANAGER WHO ADMITTED THAT THEY COULDN'T TELL WHAT CAUSED THE FAILURE OF MY TRANSMISSION AND THAT MY OIL SAMPLE PROVED THAT THE FACTORY DEFECT WAS THE MOST LIKELY CAUSE OF MY TRANSMISSION FAILURE, HE THEN PROCEEDED TO EXPLAIN THAT THEY HAD TO FOLLOW NISSAN PROCEDURE WHICH WAS A VISUAL INSPECTION. MY OIL SAMPLE TRUMPED THEIR VISUAL INSPECTION BUT THEY STILL REFUSED TO FIX MY VEHICLE EVEN UNDER THE LAWS OF THE NISSAN SETTLEMENT WHICH WAS SUPPOSED TO COVER MY VEHICLE. I FIRST STARTED HAVING PROBLEMS WHILE DRIVING, MY XTERRA ALMOST DOESN'T EVEN RUN NOW AND IS DEFINITELY NOT ROAD SAFE ANY MORE YET NISSAN STILL WON'T FIX IT.

WHEN I AM DRIVINGING AT A SLOW SPEED , MY TRANSMISSION MAKES A NOISE AND THEN FEELS LIKE IT'S GOING TO DIE, NOW I HAVE NOTICED THAT THERE IS FLUID LEAKING FROM MY RADIATOR. WHEN I RESEARCHED THE ISSUE I WAS HAVING AND REALIZISED THIS IS A RECURRING PROBLEM THAT IS BEING REPORTED BY MANY NISSAN XTERRA OWNERS AND THAT NISSION HAS BEEN AWARE OF THIS ISSUE SINCE 2007 , WHEN I ORIGINALLY PURCHASED MY XTERRA . NOW THAT I UNDERSTAND WHAT THE ISSUE IS , THE RADIATOR IS LEAKING FLUID IN TO MY TRANSMISSION AND IS DESTROYING THE TRANSMISSION AND RADIATOR . IN DOING RESEARCH ON THE PROBLEM I WAS HAVING , AND WHAT HAPPENS WHEN THIS OCCURS , I'M FRIGHTENED TO EVEN DRIVE MY XTERRA AT THIS POINT . CONSIDERING THAT NISSAN TAKES NO RESPONSIBILITY IN WHAT SHOULD CLEARLY BE A RECALL , I'M STUCK WITH A CAR THAT I'VE JUST RECENTLY PAID OFF , THAT I AM AFRAID TO DRIVE AND DO NOT HAVE $4,700 TO HAVE THE RADIOS AND TRANSMISSION REPLACED . THERE WAS NO WARNING WHEN THIS HAPPENED AT ALL . I HAVE ALWAYS MAINTAINED MY NISSAN AND THOUGHT I HAD MADE A WELL INFORMED DECISION IN MY PURCHASE . I WILL NEVER DO BUSINESS WITH THIS COMPANY AGAIN . I'M SO DISAPPOINTED IN THE SITUATION NISSAN HAS PUT MYSELF AND APPARENTLY MANY , MANY OTHERS IN . NO WAY TO DO BUSINESS .

CAR BEGAN TO GO INTO NEUTRAL WHILE ON HIGHWAY 500 MILES FROM HOME. SCARED MY FAMILY TO DEATH. LOST POWER AT A HIGH SPEED. PROBLEM EBBED BUT CONTINUED ALL THE WAY HOME. NISSAN STATED RADIATOR FLUID HAD GOTTEN INTO TRANSMISSION DUE TO DEFECT IN TRANSMISSION LINE THAT WAS PASSING THROUGH THE RADIATOR. SAME NISSAN' DEALER'S CHEAPEST SOLUTION WAS TO PUT A USED TRANSMISSION IN FOR $3,500 PLUS LABOR. I CONTRACTED WITH A PRIVATE MECHANIC. I ALSO PURCHASED A SEPARATE SYSTEM TO ROUTE THE TRANSMISSION FLUID CORRECTLY IN THE FUTURE. MECHANIC SHOWED ME THE CLUTCHES WHICH WERE DESTROYED. HE MAY STILL HAVE THEM.
