2007 Nissan Pathfinder Engine

Ref. No. 11452064 dated May 12. 2023 After contacting the servicing dealership, a reply was received acknowledging coolant and transmission fluid cross-contamination was discovered. Along with the other complaints already received, I hope this is enough to proof to finally substantiate just remedies to all who purchased a defective product.

2007 PATHFINDER WAS BEING DRIVEN ON A CITY STREET AND STALLED WHILE IN MOTION. WAS ABLE TO STEER AWAY FROM TRAFFIC. STEERING WAS HARD TO MANEUVER. AFTER REPEATED TIMES OF CRANKING IT WOULD NOT START.. VEHICLE WAS TOWED TO OWNERS RESIDENCE. WHEN BEING DROPPED OFF OWNER STARTED VEHICLE AND WAS ABLE TO MOVE IT INTO DRIVEWAY. NO CHECK ENGINE LIGHT OF ANY SORT WAS LIT. AFTER A COUPLE OF DAYS VEHICLE WAS BEING DRIVEN AROUND THE BLOCK AND STALLED AGAIN. WAITED FOR ABOUT 25 MINUTES TO COOL OFF AND ENGINE TURNED ON AGAIN BUT STALLED . AFTER A COUPLE OF REPEATED TRYS WAS ABLE TO DRIVE VEHICLE BACK INTO DRIVEWAY. AGAIN NO CODES LIT.

RADIATOR HAS CRACKED AND LEAKED INTO THE TRANSMISSION

I WAS DRIVING AND SUDDENLY THE CHECK ENGINE LIGHT CAME ON, I DROVE HOME AND THE NEXT WEEK I WENT TO REPLACE MY BRAKES AND ASK THE WORKSHOP TO DO A SCAN TO LET ME KNOW WHY THE LIGHT IS ON, THEY DID AND 2 CODES CAME UP WHICH THE SHOP SAID THEY DID NOT SEE BEFORE SO THEY CLEARED THE SYSTEM AND SAID IF IT COMES ON AGAIN TO TAKE IT BACK SO THEY CAN FULLY INVESTIGATE. I WENT ON 9/28 TO ANOTHER WORKSHOP THEY DID A SCAN AND THE CODE P1772 CAME ON AFTER INSPECTING THE MECHANIC SHOWED ME THE RADIATOR CAP WITH SOME THICK GOOEY STUFF TELLING ME THE RADIATOR IS BAD AND THE COOLANT IS MIXING WITH TRANSMISSION FLUID AND VICE VERSA. BEFORE THIS THE CAR WOULD RUN AND WHEN I AT A STOP SIGN AND TRY TO MOVE IT WOULD REV TO 4-5 STALLS AND THEN MOVE, THEY ARE ALSO TIMES OF SUDDEN JERK AND ACCELERATION. THEY HAVE ALSO BEEN TWICE WHEN I TRIED TO REVERSE THE VEHICLE WOULD NOT MOVE, I HAD TO TURN OFF THE ENGINE THEN RESTART BEFORE I COULD REVERSE.. DEFECTIVE RADIATOR CRACKS LEADING TO COOLANT MIXING WITH TRANSMISSION FLUID, NOW NEED TO REPLACE RADIATOR AND TRANSMISSION

RADIATOR CRACKED, LEAKED INTO TRANSMISSION CAUSING TRANSMISSION FAILURE

COOLANT CONTAMINATION, GETTING MIX WITH TRANSMISSION OIL

TL* THE CONTACT OWNS A 2007 NISSAN PATHFINDER. THE CONTACT STATED THAT THE VEHICLE FAILED TO START. THE VEHICLE WAS TOWED TO HERITAGE NISSAN (1500 VETERANS MEMORIAL HWY NE, ROME, GA 30161) WHERE IT WAS DIAGNOSED THAT THERE WAS A LEAK IN THE COOLANT AND RADIATOR THAT LEAKED INTO THE TRANSMISSION, WHICH CAUSED THE VEHICLE NOT TO START. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC AND REPAIRED. THE MANUFACTURER WAS CALLED AND THE CONTACT WAS AWAITING A CALL BACK. THE FAILURE MILEAGE WAS 107,859. *TT *TR

IN 2007, I PURCHASED A NEW NISSAN PATHFINDER, UNAWARE OF ANY DEFECTS. IN 2011, I BEGAN HAVING PROBLEMS WITH MY TRUCK NOT PRODUCING HEAT WHILE IT WAS IDLE. NISSAN STATED THAT THE COOLANT LOOKED DARK AND ADVISED ME THAT THEIR WAS AIR IN THE LINE. ONCE AGAIN, I'M HAVING TROUBLE WITH THE HEAT AND NOW I'M BEING TOLD THE TRANSMISSION AND COOLANT FLUIDS ARE INTERMIXED, AND THAT IT WOULD COST BETWEEN $7 AND 8 THOUSAND DOLLARS BECAUSE I NEED TO REPLACE BOTH THE TRANSMISSION AND THE RADIATOR. WHEN I TOOK MY TRUCK TO NISSAN IN 2011, AND THEY KNEW THE COOLANT WAS DARK, I SHOULD HAVE BEEN MADE AWARE OF THE DEFECT WITH THE RADIATOR ASSEMBLY BECAUSE MY ISSUES MOST LIKELY HAD ALREADY STARTED, AND NOW, IT'S GOTTEN WORSE. I WAS NEVER ADVISED OF THIS PROBLEM UNTIL NOW.

I BOUGHT A VEHICAL HAS BAD TIRE PRESSURE SENSORS LIGHTS ALWAYS ON I NEVER KNOW IF TIRES ARE REALLYHAVING AN ISSUE.

TRUCK WAS JERKING A COUPLE OF WEEKS AGO THEN WENT TO DIRECT FIX.COM, WHICH SAID TO LOOK FOR CONTAMINATION IN THE COOLANT RESERVOIR. SO I REPLACED THE RADIATOR, FLUSH THE TRANSMISSION, REPLACE TRANSMITTER AND FILLED OEM TRANSFLUID. RAN GOOD FOR TWO WEEKS AND TRAN'S JUST WENT BANK. IREC

I WAS TOLD BY THE DEALERSHIP THERE WAS A BAD TIMING CHAIN - CALLED NISSAN AND THEY SAID THEY WOULD NOT FINANCIALLY ASSIST WITH THE REPAIR. THERE APPEARS TO BE A CIVIL LAWSUIT REGARDING THIS ISSUE.

TIMING CHAIN TENSION SYSTEM FAILED AT 80,000 MILES.

TIMING CHAIN FAILURE AT 80,000 MILES WHICH SHOULD NOT HAPPEN

DEFECTIVE DRIVE CHAINS, AS DESCRIBED IN A NISSAN TECHNICAL SERVICE BULLITEN. THESE WERE ABOUT TO BREAK AND DESTROY THE ENGINE.

TL* THE CONTACT OWNS A 2007 NISSAN PATHFINDER. WHILE DRIVING 50 MPH AND MERGING INTO THE SLOW LANE, THE VEHICLE AGGRESSIVELY LUNGED FORWARD. THE VEHICLE SHOOK VIGOROUSLY AND THE CHECK ENGINE AND CHECK OIL WARNING INDICATORS ILLUMINATED. THE VEHICLE STALLED AND FAILED TO RESTART. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THERE WAS ENGINE SLUDGE. THE TRANSMISSION AND RADIATOR FAILED DUE TO THE EXTERNAL COOLER FAILURE. THE RADIATOR, TRANSMISSION, AND EXTERNAL COOLER ALL NEEDED TO BE REPLACED WITH AFTERMARKET PARTS, ACCORDING TO THE DEALER. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 134,000.

TRANSMISSION COOLER INSIDE THE RADIATOR CRACKED AND GOT COOLANT IN THE TRANSMISSION, CAUSING THE TRANSMISSION TO DIE. WE WENT TO TURN THE CAR ON AND IT WOULDN'T START, FROM THERE WE TOWED IT TO A MECHANIC WHO TOLD US WHAT HAD HAPPENED.

RADIATOR COOLANT IS LEAKING INTO TRANSMISION, WHICH COULD RESULT IN CATASTROPHIC ENGINE FAILURE

RADIATOR CRACKED AND WATER WENT INTO THE OIL AND IT MIXED....PER REP AND MECHANIC AT NISSAN DEALER. PROBLEM CAUSED BY RADIATIOR NOT BEING BUILT PROPERLY AT FABRIC. THIS PROBLEM CAUSED VEHICLE TO SHAKE VIOLENTLY WHILE DRIVING. VERY UNSAFE.

TL* THE CONTACT OWNS A 2007 NISSAN PATHFINDER. THE CONTACT STATED THAT THERE WAS TRANSMISSION FLUID LEAKING INTO THE RADIATOR. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT IT WAS MOTOR OIL LEAKING INTO THE RADIATOR. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 103,000. THE VIN WAS NOT AVAILABLE.

THE TRANSMISSION ON MY 2007 NISSAN PATHFINDER STARTED SLIPPING SO I HAD IT LOOKED AT AND FOUND OUT THE COOLANT LEAKED INTO THE TRANSMISSION. I HAVE 118,000 MILES ON IT AND UNFORTUNATELY IT LOOKS LIKE I AM OUT OF LUCK. I AN VERY DISAPPOINTED IN NISSAN SINCE THEY KNOW THE FAILURE DOES NOT OCCUR UNTIL ABOUT 90,000 MILES.

MY SUV WAS DIAGNOSED WITH A DEFECTIVE RADIATOR AND NOW HAS ISSUES WITH THE TRANSMISSION COOLER PIPES SPLITTING CAUSING CROSS CONTAMINATION BETWEEN THE RADIATOR COOLANT & TRANSMISSION FLUID. WHICH RESULTED IN A FAILURE TO THE AUTOMATIC TRANSMISSION. THE CROSS CONTAMINATION HAD TO HAVE A NEW TRANSMISSION, TRANSMISSION COOLER HOSES & RADIATOR REPLACED. READING MULTIPLE SITES IT APPEARS NISSAN KNOW ABOUT THE DEFECT AND DIDN'T WARN IS CUSTOMERS, EVEN WHEN I TOOK MY CAR TO GET SERVICED AT THE NISSAN DEALERS. THIS IS BAD BUSINESS AND CUSTOMERS SHOULD NOT BE FINANCIALLY RESPONSIBLE. I HOPE THE PERSON READING THIS HAS THE COURAGE TO DO SOMETHING ABOUT IT. IT APPEARS THAT CORPORATIONS HAVE THE POWER. THANK YOU.

TL* THE CONTACT OWNS A 2007 NISSAN PATHFINDER. THE CONTACT STATED THAT TRANSMISSION FLUID IN THE VEHICLE WAS LEAKING ONTO THE RADIATOR. THE VEHICLE WAS TAKEN TO THE DEALER ON TWO OCCASIONS WHERE IT WAS DETERMINED THAT THE CONTROL MODULE FAILED. THE VEHICLE WAS THEN TAKEN TO AN INDEPENDENT MECHANIC WHO DETERMINED THAT THE LEAK CAME FROM INSIDE THE RADIATOR. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 84,000. THE VIN WAS NOT AVAILABLE.

ENGINE NOISE COMING FROM THE SECONDARY TIMING CHAIN AND TENSIONERS. THE FIRST TIME I TOOK IT TO NISSAN DEALER THEY TOLD ME THEY COULDN'T FIND ANYTHING WRONG. WHEN I BROUGHT IT BACK MONTHS LATER THEY TOLD ME I HAD LOW OIL IN ENGINE AND COMBINED WITH I WAS PAST THE 60,000 WARRANTY NOW (67,861) THAT I WOULD NOT BE COVERED UNDER WARRANTY. THEY KNEW THIS WAS A PROBLEM AND CLAIMED THAT I HAD NO RECORD OF IT BEING A PROBLEM SINCE THEY COULDN'T "FIND" ANYTHING WHEN I BROUGHT IT IN THE FIRST TIME. TWO DEALERSHIPS TOLD ME THAT IT WAS JUST A NOISE WHEN IN FACT NISSAN HAS KNOWN ABOUT THE TIMING CHAIN ISSUE THIS WHOLE TIME. I WAS TOLD TO PAY FOR THE REPAIR MYSELF WHICH WAS ABOVE $1,500.00. *TR

TL* THE CONTACT OWNS A 2007 NISSAN PATHFINDER. WHILE DRIVING AT ANY SPEED WHEN THE ACCELERATOR PEDAL WAS ACTIVATED, THE VEHICLE BARELY MOVED. THE VEHICLE WAS TOWED TO A MECHANIC WHO DIAGNOSED THAT THERE WAS CROSS CONTAMINATION OF RADIATOR FLUID THAT LEAKED INTO THE TRANSMISSION. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 95,000.

BEGINNING IN NOVEMBER 2014, THE HEATER WOULD NOT BLOW OUT WARM OR HOT AIR IF THE CAR WAS NOT TRAVELING ON THE INTERSTATE. AT SPEEDS BELOW 50MPG, ONLY COOL OR COLD AIR WOULD BLOW OUT OF THE HEATER VENTS AND AT AN IDLE, ONLY COLD AIR WOULD BE EMITTED. THE RADIATOR WAS FLUSHED THREE TIMES IN AN EFFORT TO REMEDY THIS PROBLEM. OUR MECHANIC THOUGHT THERE COULD BE A BLOCKAGE IN THE LINE DUE TO THE AGE OF THE VEHICLE. ONCE FLUSHED, THE HEAT WOULD WORK FOR ABOUT 45 DAYS. THERE WERE MONTHS OF MY DRIVING TO WORK WITHOUT ANY REAL HEAT IN THE WINTER OF 2014. AFTER FLUID CHANGES AND RADIATOR FLUSHES, THE 2007 NISSAN PATHFINDER NOW HAS 111,000 MILES ON IT. THE AIR CONDITIONING IS WORKING THIS SUMMER, BUT TOWARDS THE END OF MAY 2015, THE TRANSMISSION STARTED "JUMPING". THIS USUALLY OCCURS AROUND 40-45 MPH. THE ENGINE WILL REV AT A HIGH RPM WHILE TRAVELING DOWN AN INCLINE OR A HILL. THE TRANSMISSION FEELS AS THOUGH IT IS "GOING OUT" AND UPON READING REVIEWS ON YOUR SITE, THIS SEEMS TO BE A COMMON PROBLEM WITH THIS MAKE AND MODEL OF VEHICLE. THERE ARE TIMES WHEN YOU CAN HEAR THE TRANSMISSION "CLUNK" INTO GEAR WHEN STARTING OR STOPPING THE ENGINE.
