ENGINE COOLANT HAS LEAKED FROM THE RADIATOR INTO THE TRANSMISSION FLUID COOLING SECTION OF THE RADIATOR, THEN INTO THE TRANSMISSION RESULTING IN OVER $5200 IN A TRANSMISSION REBUILD. HAVING CHECKED VARIOUS WEB SITES I NOTICE THAT THIS HAS BEEN A RECURRING PROBLEM WITH THIS MODEL. MY QUESTION IS: IF NISSAN HAS KNOWN ABOUT THIS PROBLEM, WHY HAS A RECALL NOT BEEN ISSUED? ALSO, WHY SHOULD OWNERS BE RESPONSIBLE FOR FOOTING THE BILL FOR REBUILDING THE TRANSMISSION? DUE TO THE NATURE OF THIS, I WILL BE CONTACTING THE FEDERAL TRANSPORTATION AGENCY THAT PROVIDES OVERSIGHT OF VEHICLE SAFETY AND RECALLS. IT IS UNSATISFACTORY THAT NISSAN DOES NOT OWN UP TO IT'S RESPONSIBILITIES!

MY TRUCK WOULD GO IN TO GEAR BUT WOULD NOT DRIVE. I HAD IT DIAGNOSED BY A TRANSMISSION SHOP AND THEY SAID THAT THE RADIATOR WAS LEAKING WATER AND COOLANT IN TO MY TRANSMISSION AND IT WOULD NEED TO BE REPLACED. I THEN HAD MY VEHICLE TOWED TO THE NISSAN DEALER WHERE THE TECHNICIAN SAID THAT THIS IS CAUSED BY A FAULTY HOSE ON RADIATOR AND IT WAS HAPPENING TO A LOT OF FRONTIERS AND XTERRAS. WHEN MY HUSBAND QUESTIONED THE TECH ON THIS BEING A RECALL HE STATED THAT IT SHOULD BE, BUT IS NOT BECAUSE IT DOES NOT CAUSE A SAFETY ISSUE. HE TOLD US WE WOULD NEED A NEW RADIATOR, HOSES, AND TRANSMISSION. THE TRUCK BREAKING DOWN IS A SAFETY ISSUE! WE THEN HAD OUR TRUCK TOWED TO OUR NORMAL MECHANIC AND HE IS REPAIRING IT NOW.

MY NISSAN DEALER TOLD ME TODAY THAT THE TIMING CHAIN ON THE 4.0L V6 ENGINE IN MY TRUCK REQUIRES REPLACEMENT. THIS TRUCK HAS LESS THAN 60,000 MILES ON IT AND THE DEALER CHARGES $2,140 FOR THE WORK. TIMING CHAINS ARE NORMALLY EXPECTED TO LAST FOR THE LIFE OF THE VEHICLE. FAILURE OF THE TIMING CHAIN WOULD DESTROY THE ENGINE AND, IF IT OCCURRED WHILE THE VEHICLE WAS IN MOTION, COULD RESULT IN A CRASH. NISSAN HAS KNOWN ABOUT A DEFECTIVE TIMING CHAIN PROBLEM ON THIS AND RELATED ENGINES SINCE AT LEAST 2004, YET THEY CONTINUED TO USE THOSE DEFECTIVE TIMING CHAINS UNTIL APPROXIMATELY 2010. NISSAN SHOULD ISSUE A RECALL AND REPLACE THE CHAINS UNDER WARRANTY.
