I HAD MY TRANSMISSION AND RADIATOR REPLACED IN MY 05 NISSAN XTERRA IN DEC 2010 AT 69,000 MILES DUE TO DEFECT OF RADIATOR LEAKING INTO TRANSMISSION WHICH CAUSED ME TO BRAKE DOWN ON A 2 LANE HIGHWAY. THE NISSAN SERVICE/DEALER IN KINGSTON MA WHERE WE PURCHASED THE VEHICLE TRIED TO TELL US ALL THAT WAS NEEDED WAS A RADIATOR AND TRANSMISSION FLUSH BUT WE HAD ALREADY CONTACTED NISSAN CORPORATE AND FOUND OUT WE WERE ENTITLED TO A NEW TRANSMISSION AND RADIATOR ASSEMBLY DUE TO A RECALL. THEY UNWILLINGLY REPLACED BOTH ASSEMBLIES. I HAVE NOW EXPERIENCED A 2ND BRAKE DOWN ON AN ON RAMP ENTERING THE HIGHWAY AND COULD NOT MOVE MY CAR AS THE TRANSMISSION AGAIN FAILED AT 153,900 MILES. I HAD IT TOWED TO THE NISSAN SERVICE/DEALER IN KINGSTON MA AND WAS INFORMED THE TRANSMISSION WE HAD PUT IN 2010 WAS ONLY UNDER WARRANTY FOR 1 YR/12000 MILES AND I AM RESPONSIBLE FOR ALL REPAIR COSTS. I HAVE TO THINK THAT THE ORIGINAL REPAIR WAS NOT DONE PROPERLY AND THE SAME PROBLEM EXISTED IN THE NEW ASSEMBLIES THAT WERE PUT IN AS A NEW TRANSMISSION SHOULD LAST LONGER THAN THIS. I FEEL MY SAFETY AND THE SAFETY OF OTHER MOTORISTS WAS PUT AT RISK DUE TO THESE PROBLEMS AS SEVERE ACCIDENTS COULD HAVE OCCURRED DUE TO THE FACT THAT THE MY VEHICLE LOST THE ABILITY TO MOVE AT ALL ON THE HIGHWAY IN TWO DIFFERENT INCIDENTS. NISSAN SHOULD BE HELD RESPONSIBLE FOR NOT FIXING THE INITIAL PROBLEM PROPERLY. *TR

I HAVE A 2005 NISSAN XTERRA AND I'M HAVING A PROBLEM WITH THE TRANSMISSION I PLACE IT IN GEAR AND HEARD A POP AND THEN THE VEHICLE DID NOT WANT TO GO ANYWHERE. AFTER DOING SOME RESEARCH I HAVE COME TO THE CONCLUSION THAT THERE ARE MANY OTHERS HAVING THE SAME PROBLEM. IF NISSAN KNOWS THIS IS A PROBLEM THEY SHOULD BE HELD RESPONSIBLE FOR REPAIRS NO MATTER WHAT THE MILEAGE IS ON THE VEHICLE. I WILL NOT BE BUYING ANOTHER NISSAN IF THEY DON'T WANT TO STAND BEHIND THERE PRODUCTS. A COUPLE OF YEARS AGO THE FUEL SENDING UNIT WENT BAD AND IT COST ME 1200.00 DOLLARS TO HAVE IT FIXED AND IT WAS ALSO A KNOWN PROBLEM. *TR

THE CAR HAD BEEN DRIVING FINE AND THEN ALL OF A SUDDEN IT WOULD NOT SHIFT INTO A HIGHER GEAR. THE RPMS WOULD JUST INCREASE. AT TIMES THE CAR WOULD NOT EVEN GO INTO ANY GEAR WHAT SO EVER. FINALLY MANAGED TO GET IT TO A DEALERSHIP WHERE THEY TOLD ME IT WAS THE TRANSMISSION FLUID MIXING WITH THE RADIATOR FLUID. TOLD ME I NEEDED BOTH REPLACED AND QUOTED OVER $6500 FOR THE FIX.

TL* THE CONTACT OWNS A 2005 NISSAN XTERRA. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 25 MPH, THE ENGINE RPMS INCREASED EXCESSIVELY BUT THE VEHICLE FAILED TO ACCELERATE. THE CONTACT MENTIONED THAT THE CHECK ENGINE WARNING LIGHT WAS ILLUMINATED. THE VEHICLE WAS TOWED TO A DEALER WHERE IT WAS DIAGNOSED THAT THE RADIATOR FLUID WAS MIXED WITH THE TRANSMISSION FLUID. AS A RESULT, THE TRANSMISSION WOULD NEED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE AND CURRENT MILEAGE WAS 116,208.

WHEN DRIVING AT VARIOUS SPEEDS I BEGAN TO NOTICE THE ENGINE BOGGING DOWN WHEN CHANGING GEARS. UPON TAKING IT TO MY MECHANIC I WAS TOLD THAT THERE WAS A LEAK BETWEEN THE TRANSMISSION AND ENGINE COOLANT SYSTEMS. THE FIX WOULD REQUIRE A REPLACEMENT OF BOTH SYSTEMS TOTALLY APPROX. $6000! APPARENTLY THIS IS A "KNOWN ISSUE" WITH 2005-2010 XTERRAS. UPON CONTACTING NISSAN I WAS TOLD THAT SINCE MY VEHICLE WAS OVER 100,000 MILES THAT THERE WAS NOTHING THAT THEY COULD DO FOR ME. IF THIS IS A KNOWN ISSUE, AND A RATHER MAJOR ONE AT THAT, I'M NOT SURE WHY THERE HASN'T BEEN ANY RECALLS OR SOME KIND OF FIX. *TR

MY DAUGHTER WAS DRIVING OUR 2005 NISSAN XTERRA AND SUDDENLY THE CAR WOULD NOT ACCELERATE, SHE FLOORED IT AND AFTER A WHILE IT GOT BACK UP TO SPEED ENOUGH FOR HER TO PULL OFF THE HIGHWAY THROUGH 3 LANES OF TRAFFIC AND ONTO THE SIDE ROAD. THE CAR NOW SITS IN MY DRIVEWAY BECAUSE IT WILL COST OVER 6,000 TO REPAIR (THE CAR BOOK VALUE IS A BIT LESS THAN THAT). THE TRANSMISSION/RADIATOR WILL NEED TO BE REPLACED BECAUSE THE FLUID HAS GOTTEN INTO THE TRANSMISSION. NISSAN IS AWARE OF THIS ISSUE AND STILL CONTINUES TO LET THEIR CUSTOMERS BEAR THE BRUNT OF THEIR DEFECTIVE PRODUCT. THANK GOD MY DAUGHTER WAS NOT KILLED ON THE HIGHWAY DUE TO THE SUDDEN LOSS OF SPEED/CONTROL. I HOPE IT DOES NOT TAKE SOMEONE DYING FROM THIS DEFECT IN ORDER FOR THEM TO RECALL AND PAY TO REPLACE/REPAIR THIS ISSUE. PERHAPS SOMEONE ALREADY HAS BUT NO ONE KNOWS YET. I HAD TO DRIVE THE CAR HOME FROM THE MECHANIC SHOP JUST A FEW MILES AND WAS UNABLE TO ACCELERATE SEVERAL TIMES AND WAS ALMOST HIT TWICE. WE HAVE BOUGHT HER A NEW CAR (NOT A NISSAN) AND ARE TRYING TO FIND SOMEONE TO PURCHASE THE NISSAN AND FIX IT THEMSELVES OR SELL IT FOR PARTS. WE NOW HAVE A USELESS AUTO THAT IS NO LONGER WORTH A DIME AND WE ARE OUT SEVERAL THOUSAND IN RESALE VALUE. HOW CAN THIS BE LEGAL? WHEN WILL THIS FINALLY BE TAKEN SERIOUSLY? *TR
