I HAVE AN AUTOMATIC AND NOTICED THAT MY 07 NISSAN XTERRA WAS STRUGGLING TO CHANGE GEARS. WHEN IT DID NOT GO AWAY AFTER SEVERAL MONTHS, I TOOK IT INTO LOCAL REPAIR SHOP. THEY FOUND THAT THE RADIATOR WAS FULL OF A BROWN MILK SHAKE SUBSTANCE. THEY DETERMINED THAT TRANSMISSION FLUID HAD LEAKED IN THE RADIATOR AND MIXED WITH THE ANTIFREEZE. THE SHOP REPLACED THE RADIATOR. FLUSHED THE ANTIFREEZE SYSTEM AND THE TRANSMISSION FLUID. 6 MONTHS LATER, THE TRANSMISSION STARTED STUTTERING WHEN IT WAS CHANGING GEARS AT 45 - 50 AND 65-70. I TOOK THE CAR INTO A LOCAL AAMCO. ONCE I ADVISED THE SERVICE REP WHAT TYPE OF CAR I HAD, HE LAUGHED AND SAID THEY THAT HAD ALREADY REBUILT OVER 30 XTERRA TRANSMISSION. THEY CHECKED THE TRANSMISSION AND ADVISED THAT IT NEEDED TO BE REBUILT AND PROVIDED ME WITH AN REPAIR ESTIMATE OF $ 4200. THEY ADVISED TO CALL NISSAN CONSUMER AFFAIRS TO SEE WHAT THEY WOULD OFFER TO DO. THEY ALSO ADVISED OF A CLASS ACTION LAWSUIT AGAINST NISSAN FOR THIS KNOWN DEFECT. I HAVE BEEN UNABLE TO FIND ANY INFORMATION ON THIS LAWSUIT. *TR

VEHICLE ABRUPTLY STALLED WITHOUT WARNING WHEN MAKING A LEFT HAND TURN. ONCOMING TRAFFIC WAS FORCED TO STOP. A SERIOUS, POSSIBLY DEADLY, ACCIDENT COULD HAVE OCCURRED IF THE ONCOMING TRAFFIC HAD NOT STOPPED. THE VEHICLE HAD SHUDDERING DURING ACCELERATION PRIOR TO THIS INCIDENT BUT HAD NEVER GIVEN ANY INDICATION IT WOULD STALL UNEXPECTEDLY. THE VEHICLE HAD BEEN MAINTAINED BY NISSAN AND NO ISSUES WERE BROUGHT TO MY ATTENTION DURING THIS SERVICE. WHEN NISSAN DIAGNOSED THE VEHICLE THEY FOUND THAT THE TRANSMISSION COOLER HAD LEAKED AND ALLOWED TRANSMISSION FLUID AND ENGINE COOLANT TO MIX. THIS LEAD TO TRANSMISSION DAMAGE AND UNSAFE, UNEXPECTED FAILURE OF THE TRANSMISSION. NISSAN ALSO SAID THEY HAD KNOWN ABOUT THIS COMMON FAILURE FOR MANY YEARS. I WAS NEVER INFORMED OF THIS DANGEROUS DESIGN FLAW. *TR

WE JUST DISCOVERED OUR 2007 NISSAN XTERRA (117,000 MILES) IS ONE OF THE MANY NISSANS TO HAVE THE RADIATOR CRACK AND LEAK COOLANT INTO THE TRANSMISSION AND TRANSMISSION FLUID INTO THE COOLING SYSTEM. THE CAR NOW NEEDS AROUND $6,000 IN REPAIRS TO FIX THE TRANSMISSION, RADIATOR, ETC. WE BOUGHT A WARRANTY FROM THE DEALER WHEN WE BOUGHT THE CAR IN 2010. THE WARRANTY COVERS THE TRANSMISSION UP TO 120,000 MILES. WE HAVE TAKEN THE CAR TO THE DEALERSHIP FOR THE LAST FIVE YEARS FOR REGULAR SERVICE AND WAS NEVER INFORMED ABOUT THIS DESIGN DEFECT. THE DEALER WILL NOT FIX THE TRANSMISSION AS COVERED IN THE WARRANTY. *TR

MY CAR BEGAN SHUTTERING BAD ENOUGH THAT I WAS AFRAID THAT IT WAS GOING TO STALL OR THAT I WOULD GET INTO AN ACCIDENT. THANKFULLY, I DIDN'T I FOUND OUT THAT A FAULTY RADIATOR LEAKED INTO THE TRANSMISSION. APPARENTLY, THIS IS A WELL KNOWN PROBLEM. I AM BEING TOLD BY NISSAN THAT IT WILL COST $7,000 TO REPAIR/REPLACE THE RADIATOR, HOSES, TRANSMISSION ETC. MY MILEAGE IS JUST OVER 106,000 MILES SO, LIKE EVERYONE ELSE, I WILL GET NO HELP FROM NISSAN IN MAKING THESE REPAIRS. I CAN'T AFFORD TO FIX IT AT THIS TIME SO IT WILL HAVE TO SIT AND WAIT WHILE I WILL PRAY THAT THERE IS A RECALL SOON. *TR

ON 3/28/15, PARKING MY 2007 NISSAN XTERRA (126,0000 MILES) IN TAMPA, FL. BEFORE I HAD THE CAR IN "PARK", THERE WAS A LOUD NOISE, THE ENGINE STARTED SMOKING AND A LOT OF PURPLE/GREEN/GRAY FLUID LEAKED OUT FROM THE BOTTOM OF MY CAR. AFRAID TO MOVE THE CAR, AAA TOWED IT TO THE NISSAN DEALERSHIP IN TAMPA. WHEN THE TOW TRUCK DRIVER ARRIVED AND SAW THE COLOR OF THE FLUIDS, HE QUICKLY DETERMINED THAT MY CAR HAD LEAKED BOTH TRANSMISSION AND RADIATOR FLUID. HE SAID HE HEARD THAT THIS WAS A PROBLEM WITH NISSAN XTERRAS. I WAS SHOCKED! SINCE PURCHASING NEW IN DECEMBER 2006, I HAVE ALWAYS TAKEN MY CAR TO NISSAN FOR ALL SERVICE. OTHER THAN A FEW OIL CHANGES, ALL SERVICE HAS BEEN PERFORMED BY NISSAN DEALERSHIPS AND THEIR CERTIFIED TECHNICIANS. JUST PRIOR TO THIS INCIDENT, MY CAR HAD BEEN SHAKING. I HAD BEEN TO NISSAN WITH THIS COMPLAINT IN THE PAST, BUT AFTER REPAIRS WERE MADE IT SEEMED TO GO AWAY. AT NO TIME WAS A TRANSMISSION PROBLEM MENTIONED AS A POSSIBILITY. I HAVE LIVED IN DIFFERENT AREAS IN FLORIDA AND USED ONLY NISSAN DEALERSHIPS FOR SERVICE AND REPAIR, WILLING TO PAY MORE FOR REPAIRS THAN AN INDEPENDENT REPAIR SHOPS, THAT NISSAN DEALERSHIPS AND SERVICE WOULD KNOW MY VEHICLE BEST & BE PROACTIVE, ALERTING TO ANY POTENTIAL FUTURE PROBLEMS, I FELT PROTECTED. THE LAST MAJOR REPAIR WAS IN JULY 2014, AT 113,000 MILES AT AUTONATION NISSAN, DELRAY, FL. COMPLAINT WAS SEVERE SHAKING, AND STUMBLING WHEN ACCELERATING. REPAIRS WERE OVER $1,000; A TRANSMISSION ISSUE WAS NEVER MENTIONED, EVEN AFTER FURTHER REPAIRS WERE NEEDED. I WAS NEVER INFORMED OF TRANSMISSION PROBLEMS WITH XTERRAS UNTIL SATURDAY AT THE DEALER IN TAMPA, WHO SAID HE ALERTS ALL XTERRA OWNERS TO BE PROACTIVE WITH RADIATOR REPLACEMENT. AFTER THE COMMENT I DID RESEARCH ONLINE. I WAS UNAWARE OF THE CLASS ACTION SUIT SETTLED WITH NISSAN; I WAS NEVER NOTIFIED OF A PROBLEM HISTORY WITH NISSAN XTERRA TRANSMISSIONS AND RADIATORS. *TR

TRANSMISSION CONTROL UNIT FRIED BY DEFECTED RADIATOR FAILURE. I AM NOW ONE OF THE MANY 2007 XTERRA OWNERS TAKEN BY THE NISSAN MOTOR CORPORATION WHO PUT OUT A DEFECTIVE PRODUCT AND NOW REFUSE TO STAND BEHIND IT. ME AND THE WIFE WERE STOPPING TO GET A BITE TO EAT, ENDED UP BEING A FINAL STOP. AFTER PICKING UP THE FOOD THE TRUCK WOULD NOT CRANK, GAUGES WORKED, HORN AND LIGHTS BUT STILL WOULD NOT CRANK. HAD IT TOWED TO THE HOUSE AND THEN CONTACTED THE DEALERSHIP. THEN IT GETS WORST, THE DEALERSHIP "TECHNICIAN" REPLIED WITH THE EXACT SAME DESCRIPTION OF PROBLEM OVER THE PHONE THAT I GAVE TO HIM WHEN I CALLED TO HAVE IT TOWED TO THE DEALER. THE SYMPTOMS ARE NO CRANK, MILKY LOOKING RADIATOR FLUID AND THE AUTOMATIC TRANSMISSION FUSES KEEPS BLOWING. NOW I CONTACTED THE NISSAN MOTOR CORPORATION AND GOT NO "JOY" WHEN I FOUND OUT THAT THE WERE OFFERING A BIG FAT NOTHING!!!!!! I GUESS THIS IS WHAT YOU GET FOR BUYING A NISSAN :( *TR
