I PURCHASED A USED 2005 NISSAN FRONTIER SE CREW CAB WITH 86,000 MILES FOR $13,300 NOVEMBER 29TH 2013. NO WARNING OR INDICATION THAT THIS VEHICLE WAS PART OF A CLASS ACTION LAWSUIT OVER THE RADIATOR COOLED TRANSMISSION PROBLEMS. THERE WAS NO INDICATION THAT THIS VEHICLE MAY EXHIBIT SYMPTOMS THAT SEEM UNRELATED. ON AUGUST 6TH 2014 AT 99,978 MILES I TOOK MY TRUCK INTO A ASE CERTIFIED MECHANIC TO CHECK OUT THE TRANSMISSION BECAUSE OF SHUDDERING WHILE SHIFTING. THEY RAN A DIAGNOSTIC, CHECKED THE FLUIDS, AND SENSORS. AT THAT TIME THEY ASSESSED IT WAS A DIRTY SENSOR AND SENT ME ON MY WAY, AND FOLLOWED UP AFTER A FEW DAYS. THE VEHICLE WAS STILL HAVING THE SAME ISSUES AND I BROUGHT IT BACK IN. UPON FURTHER INSPECTION OF THE TRANSMISSION OIL THERE WAS A SIGNIFICANT AMOUNT OF RADIATOR FLUID IN THERE AND THE PROBLEM WAS IDENTIFIED. THE CURRENT MILEAGE IS NOW 100,600 MILES. I THEN MADE A CLAIM TO NISSAN CONSUMER AFFAIRS DEPARTMENT REGARDING THE ISSUE. AT THIS TIME I NOW FOUND ABOUT THE CLASS ACTION LAWSUIT SETTLEMENT AND THE EXTENDED WARRANTY. FREE UP TO 70K OR 80K AND A CO-PAY AFTER. I WAS NEVER INFORMED OF THIS UNTIL NOW. TUESDAY AUGUST 19TH I WAS INFORMED THAT NISSAN WAS NOT RESPONSIBLE FOR DIVULGING ANY OF THIS INFORMATION TO ME AND THAT THEY WOULD NOT COVER EVEN THE CO-PAY. IT IS AUGUST 20TH AND MY TRUCK IS CURRENTLY AT THE ASE CERTIFIED MECHANIC AWAITING THE PARTS TO COME IN TO REPLACE MY TRANSMISSION AND RADIATOR FOR $5,100 WHICH IS MUCH LESS THAN THE NISSAN QUOTE OF $6,700. I NOW HAVE A TRUCK PURCHASED 9 MONTHS AGO WITH A $5,100 MECHANIC BILL. I HAVE 28 $400 PAYMENTS TO MAKE FOR THE TRUCK IN ADDITION TO REPLACING THE POORLY MANUFACTURED TRANSMISSION AND RADIATOR. *TR

ON MY TRUCK I EXPERIENCED A SUDDEN LOSS IN POWER AND THROTTLE RESPONSE WHILE DRIVING WITHOUT WARNING, AS THE TRANSMISSION FAILED TO SHIFT GEARS PROPERLY. AFTER SPENDING $100 FOR A DIAGNOSTIC FROM A MECHANIC IT WAS FOUND THAT MY TRANSMISSION COOLER RESERVOIR IS LEAKING IN MY RADIATOR AND CAUSED CROSS CONTAMINATION BETWEEN MY ANTIFREEZE AND ATF. THE ANTIFREEZE IS GETTING INTO MY TRANSMISSION AND BOILING ONCE THE TRANSMISSION REACHES OPERATING TEMPERATURES. THE ANTIFREEZE VAPOR IS THEN CAUSING THE TRANSMISSION CLUTCHES AND BANDS TO NOT BE ABLE TO ENGAGE CORRECTLY, AND THEREFORE NOT BEING ABLE TO SHIFT UP AND DOWN THROUGH THE GEARS PROPERLY. I JUST ABOUT GOT HIT TRYING TO TURN LEFT OUT ONTO THE ROAD IN FRONT OF CROSS TRAFFIC. I AVOIDED AN ACCIDENT, BUT THIS HAPPENED WITH NO WARNING. THIS FIX IS GOING TO COST ME ANYWHERE FROM $500 TO $5,000 TO FIX DEPENDING ON THE EXTENT OF THE DAMAGE THE ANTIFREEZE IN MY TRANSMISSION CAUSED. I JUST READ THAT A FEW YEARS AGO NISSAN EXTENDED THE WARRANTY DUE TO THIS, AND I AM PAST THAT POINT, BUT THIS IS STILL UNACCEPTABLE AT ONLY 102,000 MILES. NISSAN SHOULD HAVE RECALLED THIS AND FIXED IT WHEN IT WAS JUST A COUPLE HUNDRED DOLLARS FOR A NEW RADIATOR YEARS AGO. LASTLY, MY TRUCK WITHOUT ISSUES WAS WORTH NEARLY $8K IN ITS CONDITION, NOW I'LL HAVE TROUBLE GETTING A DEALER TO PAY ANYTHING IN TRADE-IN VALUE IF I CHOOSE TO NOT FIX THE TRUCK. *TR

MY TRANSMISSION ON MY 2005 NISSAN FRONTIER COMPLETELY FAILED AND LEFT ME STRANDED ON THE INTERSTATE HIGHWAY. AFTER TOWING IT AND A LITTLE RESEARCH I FOUND OUT THAT THIS WAS A PROBLEM THAT NISSAN WAS WELL AWARE OF AND NEGLECTED TO NOTIFY ME OR DO ANYTHING ABOUT. THE TRANSMISSION COOLER HAD CRACKED LEAKING ENGINE COOLANT INTO THE TRANSMISSION. I LEARNED THAT THEY EXTENDED THE WARRANTY TO 90,000 MILES WITH A $3000 DOLLAR DEDUCTIBLE WHICH IS LAUGHABLE, CONSIDERING THAT THIS WAS A PROBLEM THAT IS GOING TO COST ABOUT THAT TO FIX ON MY OWN. NISSAN STATES ON THEIR WEBSITE THAT THEY EXTENDED THE WARRANTY FOR CUSTOMER SATISFACTION, IN REALITY THEY GOT SUED AND THAT WAS THE SETTLEMENT. NISSAN SHOULD HAVE RECALLED THESE TRUCKS YEARS AGO LIKE A MORALLY RESPONSIBLE COMPANY WOULD HAVE AND I WOULD NOT HAVE TO BE RUNNING UP CREDIT CARD DEBT TO FIX IT NOW. *TR

RADIATOR LEAK CAUSE FAILURE IN TRANSMISSION RADIATOR WAS FIXED A YEAR AGO AND WAS STILL HAVE SOME ISSUES WITH IT BUT WAS TOLD THEY THINK IT IS NORMAL TO FEEL IT SLIP GEARS WHEN DRIVING. I TRUSTED THEM AND LOST MY TORQUE CONVERTER WHILE DRIVING ON THE HIGHWAY GOING 100KM AN HOUR AND HAD NO PICKUP SPEED FROM IT. NISSAN TOLD ME AS LONG AS LIGHT IS NOT ON DON'T WORRY ABOUT IT. WHILE LIGHT DIDN'T COME ON UNTIL I HAD NO GEARS AT ALL. I AM NOT HAPPY ABOUT RISKING MY LIFE MY HUSBANDS LIFE AND THE LIFE OF 2 SMALL KIDS. ONE DAY IF NISSAN DON'T TAKE FAULT FOR THIS SOMEONE IS NOT GOING TO BE SO LUCKY AND GET HIT BY ANOTHER CAR BEFORE THEY CAN DRIFTED TO SAFETY. *TR

WHILE GETTING ON THE FREEWAY, I ACCELERATED TO MERGE WITH TRAFFIC BUT WAS UNABLE TO GAIN SPEED SO I GOT OFF ON THE FIRST EXIT RAMP. HAD PLENTY OF ENGINE POWER BUT LOST TORQUE. FIRST THOUGHT, MUST BE THE TRANSMISSION SLIPPING. GOT HOME AND CHECKED THE TRANSMISSION OIL LEVEL AND IT WAS FINE, THE OIL DID NOT LOOK LIKE TRANSMISSION OIL, IT WAS DISCOLORED AND HAD A DIFFERENT FEEL TO IT. WAS ABLE TO GET THE TRUCK TO DEALER AND WAS TOLD IT NEEDED A RADIATOR AND TRANSMISSION. COOLANT HAD LEAKED INTO THE TRANSMISSION. DID MY RESEARCH AND FOUND THERE HAVE BEEN MANY COMPLAINTS ABOUT THIS PROBLEM. AS FOR THE WARRANTY,BY WHICH I STILL HAVE TO PAY OVER $2500, I BELIEVE NISSAN SHOULD HAVE HAD A RECALL ON THE 05 FRONTIER, PATHFINDER, AND PAID FOR THE WHOLE REPAIR FOR THEIR USE OF WHAT I CALL DEFECTIVE PARTS.
