ENTERING 4 LANE HIGHWAY WITH 70 MPH TRAFFIC. KICKED FRONTIER INTO PASSING GEAR TO ENTER ONGOING TRAFFIC. FRONTIER STALLED AND SLOWED INSTEAD OF INCREASING SPEED. TRANSMISSION SLIPPAGE AND JERKING CAUSED MOTOR TO INCREASE RPMS. I HAD TO MOVE MY TRUCK OVER TO RIGHT OF PAVED LANE AND ONTO PULLOFF AREA IN ORDER TO PREVENT ACCIDENT. I WAS TOLD AT THE NISSAN DEALERSHIP THAT I HAD TRANSMISSION DAMAGE DUE TO RADIATOR FLUID LEAKING INTO TRANSMISSION . IT COST ME $2500 TO REPAIR A PROBLEM THAT COULD HAVE COST LIVES. I UNDERSTAND THIS WAS A PROBLEM THAT WAS NOT RECALLED BY NISSAN.

TRANSMISSION WILL NOT GO INTO GEAR DUE TO COOLANT LEAKING INTO TRANSMISSION. IT IS A MANUFACTURER DEFECT THAT NISSAN HAS KNOWN ABOUT, BUT REFUSES TO FIX. THEY DO NOT TELL THE BUYER OF THE LOOMING CATASTROPHIC FAILURE, AND CONTINUED TO MANUFACTURE THE VEHICLES FOR SEVERAL MORE YEARS EVEN AFTER DISCOVERING THE PROBLEM, PROBABLY BECAUSE IT FAILS AFTER THE WARRANTY IS UP. I NOW HAVE A TRUCK THAT I BOUGHT JUST A LITTLE OVER A YEAR AGO FOR $17000 THAT WILL NOT MOVE. THE COST TO FIX THE PROBLEM CAN RANGE ANYWHERE FROM $4000 TO $10000 DEPENDING ON HOW MUCH DAMAGE WAS CAUSED BY THE DEFECT. IF IT WERE TO HAVE BEEN IN A WRECK AND THAT MUCH MONEY IN BODY DAMAGE WOULD HAVE OCCURRED IT WOULD BE TOTALED. HOW EVER SINCE IT IS A MECHANICAL ISSUE I AM STUCK PAYING $360 A MONTH FOR A USELESS VEHICLE, THAT EVEN IF I COULD AFFORD TO GET IT FIXED, I WOULD BE PUTTING WAY MORE MONEY INTO IT THAN IT IS WORTH. WHEN I PURCHASED IT FROM THE NISSAN DEALERSHIP IT HAD AN AS IS NO WARRANTY TAG IN THE WINDOW, BUT THAT WAS NOT TRUE. NISSAN HAD A WARRANTY FOR THAT SPECIFIC PROBLEM, BUT THE DEALERSHIP DID NOT TELL ME. WHEN I CALLED AND ASKED THE SERVICE DEPARTMENT, THE SERVICE WRITER PRETENDED NOT TO KNOW ANYTHING ABOUT IT UNTIL I STARTED GRILLING HIM ABOUT IT. HE THEN ADMITTED IT WAS A BIG PROBLEM IN 3 OF THEIR VEHICLES, THEN TOLD ME IT WASN'T HIS PROBLEM, IT WAS SALES PROBLEM AND TRANSFERRED ME TO THEM. I TALKED TO THE MANAGER, HE SAID THAT THE EXTENDED WARRANTY NISSAN OFFERED, THE ONE THEY NEGLECTED TO MENTION, EXPIRED THE MONTH BEFORE MY TRANSMISSION FAILED, AND EVEN THEN I WOULD HAVE BEEN OUT $2500 FOR A KNOWN DEFECT THAT THEY CONTINUED TO PUT IN THE VEHICLES FOR SEVERAL MORE YEARS. I WAS LUCKY IT FAILED IN A PARKING LOT AND NOT WHEN I WAS PULLING OUT INTO TRAFFIC WHERE I COULD HAVE BEEN HIT BY ANOTHER CAR AND INJURED OR KILLED! THIS PROBLEM IS NOT THE CONSUMERS FAULT, IT IS NISSANS!

TRANSMISSION FLUID COOLER FAILED CAUSING WATER TO TO GET INTO THE TRANSMISSION FLUID WHICH DAMAGED THE TRANSMISSION COMPUTER VALVE BODY AND OTHER TRANSMISSION PARTS. AFTER LOOKING @ NUMEROUS COMPLAINT ON THE WEB I HAVE LEARNED THAT THIS HAS BEEN A COMMON PROBLEM THAT NISSAN IS AWARE OF. I AM VERY DISAPPOINTED THAT NISSAN DID NOT SEND OUT ANY NOTIFICATION THAT THERE WAS A PROBLEM WITH THIS COOLER FAILING. I READ WHERE THEY EXTENDED THE WARRANTY ON SOME VEHICLE BUT NO NOTIFICATIONS WERE SENT OUT TO CONSUMERS WHO OWNED AFFECTED VEHICLES. EVEN IF THEY DID NOT DO A RECALL IT WOULD HAVE BEEN BETTER IF THEY WOULD HAVE WARNS CONSUMERS OF THE POSSIBILITY OF THIS HAPPENING. IT'S MUCH LESS EXPENSIVE TO CHANGE A RADIATOR THAN TO REBUILD OR REPLACE A TRANSMISSION! FORTUNATELY MY TRANSMISSION WENT JUST AFTER I MADE HOME FROM A TRIP. NOW I AM STUCK WITH OVER $3500.00 TRANSMISSION REBUILD THAT COULD HAVE BEEN AVOID IF NISSAN HAD DONE THE RIGHT THING BY LETTING PEOPLE KNOW THAT THEY HAD PROBLEMS WITH THEIR TRANSMISSION COOLERS.

AROUND 3 MONTHS AGO I STARTED NOTICING BETWEEN 1000 AND 2000 RPMS AND USUALLY BETWEEN 40 AND 60 MPH MY VEHICLE WOULD SHAKE LIKE I WAS DRIVING ON RUMBLE STRIPS. TURNS OUT I HAD A CROSS CONTAMINATION ISSUE WITH COOLANT AND ATF. LOOKING IN MY RADIATOR LOOKED LIKE A STRAWBERRY MILKSHAKE. ALSO DROPPED THE TRANSMISSION PAN AND FOUND A BROWN SHINEY MIXTURE OF ATF AND COOLANT. I IMMEDIATELY WENT OUT AND BOUGHT A NEW RADIATOR AND FLUIDS FOR MY TRUCK. TOTAL COST AROUND $400 SO FAR. AFTER THE FLUID FLUSHES AND NEW RADIATOR TRUCK RAN GOOD FOR ABOUT 1700 MILES. ABOUT A WEEK AGO 01/20/2016 A SLIGHT RUMBLING STARTED AGAIN. 2 DAYS AGO THE ISSUE TURNED VERY SEVERE. RPMS WERE STAYING VERY HIGH AROUND 3000 THEN WOULD GET A VERY VIOLENT CLUNK AS THE TRANSMISSION SHIFTED GEARS. THIS HAPPENED MULTIPLE TIMES. I DROVE THE TRUCK YESTERDAY AND WAS SITTING IN TRAFFIC AND WENT TO START WENT LIGHT TURNED GREEN. RPMS WENT TO ALMOST 3 WITH NO MOVEMENT FROM THE TRUCK THEN ALL OF A SUDDEN TRUCK GAVE THE VIOLENT CLUNK AGAIN AND SLAMMED INTO GEAR AND STARTED MOVING. I DID NOT DRIVE THE VEHICLE TODAY IN FEAR OF A CATISTRROPHIC BREAKDOWN OR WORSE. LIKE A TRANSMISSION LOCK UP AT 60 MPH CAUSING AN ACCIDENT. I HAVE BEEN SHOPPING TRANSMISSION SHOPS AND IT LOOKS LIKE DEFINITELY NEED TRANSMISSION REBUILD OR REPLACEMENT AT AN ESTIMATED FEE OF $3000 TO $6000. THIS IS FOR AN ISSUE THAT NISSAN HAS BEEN AWARE OF AND FAILED TO COMMUNICATE OR TAKE RESPONSIBILITY FOR WITH THEIR CUSTOMERS. ISSUE SEEM TO BE WHEN DRIVING STRAIGHT CITY OR HIGHWAY AT THE ABOVE SPEEDS AND RPMS RANGE.
