I'M A OWNER OF A 2006 NISSAN PATHFINDER. THIS VEHICLE HAS MAJOR TRANSMISSION ISSUES. VEHICLE SHUTTERS AND JERKS WHILE DRIVING 20 TO 30 MPH!!
RADIATOR COOLANT LEAK INTO TRANSMISSION CAUSED COMPLETE ENGINE FAILURE WHILE DRIVING ON A 6 LANE HIGHWAY. ABILITY TO ACCELERATE OR MAINTAIN SPEED CEASED WHEN PRESSING GAS PEDAL. COASTED ON SLIGHT DOWNWARD HILL FOR 1/4 OF A MILE OR A LITTLE MORE ALLOWING TIME TO TURN ONTO A SIDE STREET WHERE VEHICLE STOPPED COMPLETELY.
DEFECTIVE TRANSMISSION COOLANT SYSTEM CAUSED TRANSMISSION TO "SLIP" MAKING IT DANGEROUS TO DRIVE.
IN 2012, SOON AFTER WE PURCHASED OUR USED 2006 NISSAN PATHFINDER, WE KNEW IT WAS A MISTAKE. NOT ONLY DID THE FUEL INDICATOR NOT WORK (NOTICED THE DAY WE DROVE IT OFF THE LOT) THE SUV JUST DIDN'T FEEL RIGHT WHILE DRIVING. I HAVE BEEN STRANDED IN 100 DEGREE WEATHER ON NUMEROUS OCCASIONS BECAUSE THE FUEL INDICATOR SAYS I HAVE FUEL,…

IN 2012, SOON AFTER WE PURCHASED OUR USED 2006 NISSAN PATHFINDER, WE KNEW IT WAS A MISTAKE. NOT ONLY DID THE FUEL INDICATOR NOT WORK (NOTICED THE DAY WE DROVE IT OFF THE LOT) THE SUV JUST DIDN'T FEEL RIGHT WHILE DRIVING. I HAVE BEEN STRANDED IN 100 DEGREE WEATHER ON NUMEROUS OCCASIONS BECAUSE THE FUEL INDICATOR SAYS I HAVE FUEL, BUT THE LIGHT WOULD IMMEDIATELY COME ON, AND THE CAR WOULD CUT OFF & LOCK UP WHILE I WAS DRIVING IT! FAST FORWARD TO LAST YEAR, 2015, WE STARTED EXPERIENCING PROBLEMS WHEN SHIFTING INTO AND OUT OF PARK/DRIVE/REVERSE. THE TRANSMISSION WAS SLIPPING AND SOMETIMES WOULDN'T EVEN CHANGE GEARS, JUST KEEP REVVING UP THE ENGINE AND NOT GOING ANYWHERE. IT HAS LEFT MY CHILDREN AND ME STRANDED ON NUMEROUS OCCASIONS SINCE THEN. FINALLY, ABOUT 6 MONTHS AGO, THE PATHFINDER DECIDED TO NOT MOVE OUT OF PARK AT ALL AFTER CRANKED. TODAY, 9/14/16, THE TRANSMISSION LEFT ME STRANDED IN THE MIDDLE OF HEAVY 5 O'CLOCK TRAFFIC. I BARELY HAD IT PULLED OFF THE ROAD WHEN I ALMOST GOT REAR-ENDED! THE TRANSMISSION WON'T CHANGE GEARS, WON'T PROPEL THE CAR FORWARD (OR BACKWARDS) AND THE SHOP SAID IT NEEDED A WHOLE NEW TRANSMISSION, AND MAYBE A NEW RADIATOR! I AM A STUDENT AND MY HUSBAND IS IN LAW ENFORCEMENT - WE CERTAINLY DON'T HAVE AN EXTRA $4,000 LYING AROUND FOR REPAIRS TO A VEHICLE THAT SHOULD HAVE BEEN RECALLED! SO, IT IS PARKED IN OUR DRIVEWAY, COMPLETELY IMMOBILE AND WE HAVE A CAR PAYMENT COMING UP NEXT WEEK (AND EVERY MONTH AFTERWARDS). WE ARE UNDERWATER, STILL OWING $8,000 FOR A CAR WE THOUGHT WE'D DRIVE FOREVER, THAT IS VALUED AT AROUND $4,000 ON A GOOD DAY WITH NO TRANSMISSION ISSUES. SOMETHING HAS TO BE DONE! NISSAN NEEDS TO REPAIR OUR CAR ASAP!
VEHICLE WOULD HESITATE BADLY WHILE DRIVING AND ALMOST CAUSED AN ACCIDENT. WHEN TAKEN TO A MECHANIC TO FIX ISSUE, WE FOUND THAT THE TRANSMISSION FLUID HAD TURNED PINK. THE TECHNICIAN STATED THAT AT FLUID AND COOLANT HAD MIXED TOGETHER. WE HAD TO HAVE THE TRANSMISSION AND THE RADIATOR REPLACED.
WHEN I HAD ABOUT 87,000 MILES ON THE VEHICLE, IT STARTED VIBRATING WHEN I REACHED ABOUT 40 MILES AN HOUR. FROM THERE, THE HEAT WOULDN'T WORK WHEN I WOULD STOP AT INTERSECTIONS OR LETTING THE CAR IDLE. I THEN HAD MY COOLANT LEVELS CHECKED, AND DISCOVERED MY COOLANT WAS MIXED WITH RADIATOR FLUID. I HAD THE RADIATOR REPLACED, AN…

WHEN I HAD ABOUT 87,000 MILES ON THE VEHICLE, IT STARTED VIBRATING WHEN I REACHED ABOUT 40 MILES AN HOUR. FROM THERE, THE HEAT WOULDN'T WORK WHEN I WOULD STOP AT INTERSECTIONS OR LETTING THE CAR IDLE. I THEN HAD MY COOLANT LEVELS CHECKED, AND DISCOVERED MY COOLANT WAS MIXED WITH RADIATOR FLUID. I HAD THE RADIATOR REPLACED, AND THE VEHICLE DRIVES, BUT ONLY UP TO ABOUT 40 MPH. TRYING TO ACCELERATE BEYOND 40 MPH AND THE ENGINE REVS HIGH. TURNS OUT MY TRANSMISSION IS SLIPPING AS A RESULT OF THE ENGINE COOLANT GETTING INTO THE TRANSMISSION. THE ONLY WAY TO CONTINUE TO USE MY VEHICLE IS TO HAVE THE TRANSMISSION REBUILT/REMANUFACTURED AT A TUNE OF $5,000. WELL, I'VE ALREADY PAID ~$40,000 FOR THE VEHICLE, ALONE (EXCLUDING OTHER REPAIR ITEMS SINCE I'VE OWNED IT). THE FACT THAT I NEED TO REPLACE A MAJOR POWER TRAIN COMPONENT TO USE SUCH AN EXPENSIVE VEHICLE IS BEYOND COMPREHENSION. UNTIL THE MANUFACTURER (NISSAN/INFINITI USA) TAKES RESPONSIBILITY FOR THEIR MAJOR MISHAP, I DISCOURAGE EVERYONE I KNOW FROM PURCHASING THEIR VEHICLES. I BOUGHT A VEHICLE... ONE THAT SHOULD TRANSPORT ME FROM A POINT OF ORIGIN TO A POINT OF DESTINATION (WHAT IT IS DESIGNED TO DO). I DIDN'T PAY $40,000 FOR A HUNK OF PLASTIC AND METAL TO TAKE UP SPACE IN MY DRIVEWAY. SOMEONE NEEDS TO DO SOMETHING ABOUT THIS MAJOR MALFUNCTION AS EXPEDIENTLY AS POSSIBLE. THIS SHOULD NOT BE PERMITTED TO TAKE PLACE IN THE MODERN USA THAT WE LIVE IN. OTHERWISE, WHAT PURPOSE DOES FEDERAL COMMISSIONS SERVE IF THE CITIZENS AREN'T PROTECTED FROM SUCH FRAUD?
I HAVE A 2006 NISSAN PATHFINDER WITH 91,450 MILES. I NOTICE A SLIGHT SLIP IN THE TRANSMISSION ON THE WAY TO WORK. I WORK AT A AUTO REPAIR SHOP. THEY TOOK IT FOR A TEST DRIVE AND FOUND NOTHING.

I HAVE A 2006 NISSAN PATHFINDER WITH 91,450 MILES. I NOTICE A SLIGHT SLIP IN THE TRANSMISSION ON THE WAY TO WORK. I WORK AT A AUTO REPAIR SHOP. THEY TOOK IT FOR A TEST DRIVE AND FOUND NOTHING. APPROXIMATELY TWO WEEKS LATER, IT REALLY STARTED TO SLIP TO THE POINT I HAD TO PULL OVER, BECAUSE IT WAS NOT SHIFTING CORRECTLY. WHEN IT WAS BROUGHT IN TO THE SHOP AGAIN IT DID NOTHING. I CALLED THE LOCAL NISSAN DEALER IN STROUDSBURG PA AND WAS TOLD THERE WAS A "SILENT RECALL" AND TO CHECK THE FLUID IF IT WAS A MILKY COLOR, PRETTY MUCH I WAS GOING TO BE WITHOUT A CAR. I ALWAYS TOOK CARE OF MY CAR AND FOR THIS TO HAPPEN WAS A REAL BLOW. THE DEALERSHIP TOLD ME PRETTY MUCH THE REPAIR EXCEEDS THE VALUE OF THE VEHICLE. I DID CHECK THE VALUE OF MY CAR WAS APPROXIMATELY $6-7000 FOR THE SHAPE THAT IT WAS IN. THAT'S A LOT OF MONEY TO LOSE ON A VEHICLE. ALSO, THE HAZARD OF NOT SHIFTING PROPERLY COULD HAVE CAUSED AN ACCIDENT, I HAD TO PULL OFF THE SIDE OF THE HIGHWAY UNTIL I COULD GET IT TO SHIFT AND THIS KEPT REPEATING IT SELF OVER AND OVER. NISSAN HAD A CLASS ACTION SETTLEMENT, WHICH WHEN I CALLED NISSAN DIRECTLY THEY SAID IT DID NOT INCLUDE MY VIN NUMBER. I BELIEVE NISSAN KNEW THIS WAS A DEFECT AND ONLY IF YOU COMPLAINED ABOUT IT DID YOU GET ATTENTION FROM THE COMPANY. I HAD AN ADDRESS CHANGE SO I DO NOT KNOW IF I RECEIVED ANY INFORMATION ON THIS TYPE OF ISSUE. I WAS THE ONLY OWNER OF THIS VEHICLE AND BELIEVED THAT NISSAN SHOULD MAKE GOOD FOR THE REPAIRS IT WILL COST.
HAD TO HAVE STEERING COLUMN REPLACED DUE TO IT BREAKING AND CAUSING HARD STEERING AND NO CONTROL OF WHEELS. BARELY MADE IT HOME. ALSO THE TRANSMISSION HAD TO BE FLUSHED AND BY PASSED DUE TO COOLER GETTING WATER IN TRANSMISSION. BOTH OF THESE ARE SAFETY ITEMS AND NISSAN DEALER SAYS NOT ENOUGH COMPLAINTS ABOUT THESE PROBLEMS.…

HAD TO HAVE STEERING COLUMN REPLACED DUE TO IT BREAKING AND CAUSING HARD STEERING AND NO CONTROL OF WHEELS. BARELY MADE IT HOME. ALSO THE TRANSMISSION HAD TO BE FLUSHED AND BY PASSED DUE TO COOLER GETTING WATER IN TRANSMISSION. BOTH OF THESE ARE SAFETY ITEMS AND NISSAN DEALER SAYS NOT ENOUGH COMPLAINTS ABOUT THESE PROBLEMS. COST ME $3400 IN REPAIRS WHICH HAD TO BE DONE DUE TO SAFETY REASONS. THE CAR WAS IN MOTION EACH TIME ON FREEWAY AND HAD TO STOP AND GET IT TOWED TO MECHANIC BECAUSE IT WAS UNSAFE TO DRIVE ANYWHERE.
