2007 Nissan Pathfinder Engine Problems

The contact owns a 2007 Nissan Pathfinder. The contact noticed that there was unknown fluid leaking underneath the vehicle onto the ground. The contact stated no warning light was illuminated. The contact checked the radiator and noticed that the coolant was leaking from the radiator. An independent mechanic was contacted and stated that it sounded as if the transmission might have cracked; however, the vehicle was not diagnosed. The dealer was not contacted. The manufacturer was not contacted. The failure mileage was 125,000. 02/09/2023 - NHTSA #23E-012 Recall #PC948 PTH FTR XTR AB EMB NTB-23-08 Status: Remedy Not Yet Available

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.

TRANSMISSION COOLER BUSTED CAUSING TRANSMISSION FLUID TO MIX WITH COOLANT

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..

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.
