THREE WEEKS AGO NOTICED SOME TRANNY SLIPPAGE WHILE DRIVING (NORMALLY 80 MILES A DAY, 5 DAYS A WEEK AND ALL ON HIGHWAYS), CHECKED FLUID, NO PROBLEM, NO LEAKS OR NOTHING, THOUGH MAYBE JUST DRAIN AND CHANGE FLUIDS. THEN 1 WEEK AGO TODAY, I WAS AT A STOP LIGHT WHEN MY TEMPERATURE GAUGE SPIKED TO HOT AND RADIATOR STARTED TO SMOKE, STARTED TO MOVE ON THE GREEN LIGHT TO PULL OVER TO SIDE OF ROAD FROM A FOUR LANE HIGHWAY AND I WAS IN THE SECOND LANE OVER, CAR STARTED TO CHUG AND BARELY MADE IT TO THE SIDE OF ROAD BEFORE IT QUIT, THEN A GRAY COLORED FLUID STARTED DRAINING OUT OF MY RADIATOR OVERFLOW ALL OVER THE GROUND. HAD TO MAKE THE CALL TO A SHOP AND THEY KNEW EXACTLY WHAT THE PROBLEM WAS BEFORE THEY CAME AND GOT IT. THE CAR GOT TOWED TO SHOP WHERE THEY QUOTED ME $5590 FOR TOWING, NEW RADIATOR AND REBUILT TRANNY. WTF'. *TR

MY VEHICLE WAS DRIVING PERFECTLY WITHOUT ANY ISSUES AT ALL UNTIL ONE DAY ON THE WAY HOME I STOPPED AT A STOP SIGN NEAR MY HOME. THEN AS I STARTED TO PROCEED DOWN THE CITY STREET THE CHECK ENGINE LIGHT AND 4WD LIGHTS CAME ON IN THE DASH AND THE VEHICLE WOULD BARELY MOVE. I JUST BARELY GOT IT INTO THE DRIVEWAY OF MY HOME. AFTER I TURNED IT OFF I ATTEMPTED TO RESTART THE VEHICLE IT WOULD NOT EVEN ATTEMPT TO TURN OVER. I CHECKED ONLINE TO SEE WHAT WOULD CAUSE THESE SYMPTOMS TO FIND THAT HUNDREDS UPON THOUSANDS OF OTHER NISSAN OWNERS HAVE HAD THE SAME HAPPEN TO THEM. IT IS A KNOWN ISSUE OF CROSS CONTAMINATION OF RADIATOR FLUID AND TRANSMISSION FLUID DUE TO A FAULTY DESIGN IN THE RADIATOR. I HAD A MECHANIC CHECK MY ENGINE AS WELL AND HE CONFIRMED THAT THE GREY SLUDGE IN THE RADIATOR AND GRIT IN MY TRANSMISSION FLUID FIT THE SYMPTOMS OF THIS ISSUE. NOW I AM BEING TOLD I HAVE TO PAY OVER $5000.00 TO HAVE REPAIRS DONE BECAUSE OF A DESIGN FLAW THAT NISSAN REFUSES TO TAKE FULL RESPONSIBILITY FOR. I AM LUCKY THAT THIS FAILURE HAPPENED IN MY NEIGHBORHOOD VERSUS THE INTERSTATE OR IT COULD HAVE NOT ONLY LEFT ME WITH FIGURING OUT HOW TO COME UP WITH $5000.00 BUT HOW TO PAY FOR HUNDREDS OF THOUSANDS OF DOLLARS FOR REPAIR BILLS TO OTHER CARS I MIGHT HAVE CAUSED TO WRECK DO TO THIS CATASTROPHIC TRANSMISSION FAILURE.

LAST YEAR WHILE DRIVING MY CAR I BEGIN TO NOTICE A "JERKING" MOTION. I TOOK IT BACK TO THE NISSAN DEALER AND THEY SAID THAT I WOULD NEED A FLUSH AND THAT THIS WOULD TAKE CARE OF THE PROBLEM. FAST FORWARD ROUGHLY A MONTH LATER AND MY CAR COMPLETELY GAVE OUT WHILE DRIVING TO WORK. NO WARNING JUST STOPPED DRIVING IN THE MIDDLE OF THE ROAD. I HAD THE CAR TOWED BACK TO THE DEALER WHERE THEY DID A DIAGNOSTIC AND SAID THAT THE TRANSMISSION WAS "GONE" BECAUSE THE COOLANT WAS LEAKING INTO THE TRANSMISSION. I SIMPLY CAN NOT AFFORD TO GET THE REPAIRS DONE BEING A SINGLE MOTHER. I HAVE CALLED NISSAN AND FILED A COMPLAINT AND WAS TOLD THAT BECAUSE MY CAR WAS SLIGHTLY OVER 100,00 MILES THEY COULDN'T DO ANYTHING FOR ME. I FEEL AS THOUGH THIS IS S DEFECT IN THE EQUIPMENT THAT NISSAN IS SEEKING AND THE MILEAGE SHOULD NOT MATTER. THERE SHOULD BE SOME SORT OF RESOLUTION ON THE MATTER. AS IT STANDS MY CAR HAS BEEN IMMOBILE FOR THE PAST COUPLE MONTHS AND I AM STILL MAKING PAYMENTS. IT'S A SAD SITUATION AND NISSAN SHOULD BE ASHAMED, SOMETHING HAS TO BE DONE.

I PURCHASED A 2007 NISSAN XTERRA, FOLLOWING MY GRADUATION FROM COLLEGE IN 2007. IT WAS THE FIRST AND ONLY NEW CAR I'VE PURCHASED. I HAVE BEEN METICULOUS ABOUT THE MAINTENANCE AND UPKEEP OF THE VEHICLE THE ENTIRE TIME I'VE OWNED IT. APPROXIMATELY 3 MONTHS AGO, IT STALLED WHILE I WAS DRIVING, THE CHECK ENGINE LIGHT CAME ON, AND I HAD TO HAVE IT TOWED HOME. THE XTERRA WAS DIAGNOSED WITH THE VERY COMMON (AND SEEMINGLY CRIMINAL) COOLANT AND TRANSMISSION CONTAMINATION. I WAS TOLD IT WILL COST $5, 500 TO REPAIR MY XTERRA, IT REQUIRES A NEW TRANSMISSION AND RADIATOR, IT IS NON-DRIVABLE. I'VE SPENT $2,000 IN RENTAL CAR COSTS OVER THE LAST 2 MONTHS, THE DIAGNOSIS OF THE VEHICLE TOOK 4 WEEKS BY NISSAN. I CAN'T AFFORD TO PAY $5,500 TO REPAIR MY XTERRA. THE TRANSMISSION AND COOLANT CONTAMINATION ISSUE HAS LONG BEEN A KNOWN ISSUE BY NISSAN, PREVIOUS CLASS ACTION SETTLEMENTS DID NOTHING TO HELP THE CONSUMER. I DON'T UNDERSTAND WHY GOVERNING AGENCIES WON'T HOLD NISSAN ACCOUNTABLE. NISSAN HAS KNOWINGLY SOLD CONSUMERS DEFECTIVE VEHICLES FOR YEARS. THIS IS FRAUD AND SHOULD BE PUNISHABLE IN A COURT OF LAW. NISSAN SHOULD BE MORE PROACTIVE AND DO THE RIGHT THING IN ADDRESSING AND RECTIFYING THIS KNOWN DEFECT IN SEVERAL OF IT'S VEHICLES MADE OVER THE COURSE OF SEVERAL YEARS. THE CONSUMERS ARE SUFFERING. WE HAVE TO DO THE RIGHT THING, OR ELSE WE ARE HELD ACCOUNTABLE. I DON'T HAVE ANY OPTIONS AT THIS POINT AND IT'S NOT FAIR I DID WHAT I WAS SUPPOSED TO , INCLUDING PAYING $24,000 FOR A VEHICLE I CAN'T DRIVE AND THAT HAS NO TRADE-IN VALUE. NISSAN, WHY DO YOU KNOWINGLY HURT YOUR TRUSTING CUSTOMERS? UNFAIR; PATHETIC YOU CONTINUE TO BE ALLOWED TO GET AWAY WITH YOUR CRIMINAL BEHAVIOR, AND SAD FOR THE CONSUMERS WHO TRUSTED YOUR COMPANY AND YOUR PRODUCT.
