I HAVE A 2007 NISSAN FRONTIER WITH 68,000 MILES. NO MAJOR ISSUES UNTIL NOW. STARTED HAVING A TRANSMISSION NOISE DURING ACCELERATION. 10/2016, TOOK MY TRUCK TO MY LOCAL AUTO MECHANIC AND FOUND TRANSMISSION FLUID LOW. NO SIGNS OF LEAKS. ALSO CHECK COOLENT AND NO PROBLEMS SEEN. 11/5/16 I HEAD A POP AND SAW FLUID RUNNING OUT OF COOLENT OVERFLOW. TRANSMISSION STATED SLIPPING. 11/9/16 TOOK TRUCK TO MY LOCAL AUTO REPAIR SHOP AND THEY SEE THE COOLENT IS MIXED WITH OIL. ON 11/15/16 PER MY LOCAL NISSAN DEALER I HAVE A CRACK IN MY TRANS COOLENT SYSTEM WHICH IS MIXING TRANSMISSION AND COOLENT FLUID. IN RESULT DAMAGED MY TRANSMISSION AND REQUIRES REPLACEMENT. HE HAD ASK ME TO CALL NISSAN FOR ADDITION ASSISTANCE. I WAS ALSO TOLD BY MY LOCAL NISSAN DEALER THAT THIS PROBLEM COULD HAVE BEEN RESOLVED BY A RADIATOR REPLACEMENT. ON 11/9/2016 I CONTACTED NISSANUSA AND I WAS HUNG UP ON TWICE. I FINALLY GOT IN TOUCH WITH A DECENT PERSON THE SET ME UP WITH A CASE. I ASKED FOR A DESCRIPTION OF THE DETAILS OF THE WARRANTY AND THEY SAID IT WOULD BE EMAILED. 11/15/2016, I'M STILL WAITING FOR THAT EMAIL. I CALLED AGAIN AFTER GETTING ONE RUDE PERSON AND WAS PUT ON HOLD THEN DISCONNECTED. I CALLED BACK ASKING FOR FINANCIAL ASSISTANCE. I SHOULD BE GETTING A CALL TOMORROW. ALSO, I WAS TOLD ABOUT THE ISSUE A YEAR OR TWO AGO BY ANOTHER NISSAN OWNER. WHEN I CONTACTED MY LOCAL DEALER TO ACQUIRE ABOUT THE PROBLEM AND AWARE TO THEY KNEW NOTHING ABOUT IT. ALSO, THEY DID NOT HAVE INFO OF ANY PREVENTIVE MEASURES THE COULD PREVENT THIS PROBLEM. IF THIS WAS A KNOW ISSUE THE WE SHOULD HAVE BEEN NOTIFIED BY NISSAN.

THE TRUCK BEGAN LOSING POWER BECAUSE IT WOULD NOT SHIFT INTO LOWER GEARS. THIS PUT US AT RISK AT HIGHER SPEEDS. THE PROBLEM GOT WORSE AND WE TOOK IT TO THE NISSAN DEALER. WE LEARNED THAT NISSAN KNEW OF THE ISSUE, BUT FAILED TO NOTIFY US. THEY KNOWINGLY LET US DRIVE A DANGEROUS TRUCK FOR YEARS.. WE WERE LUCKY WE BROUGHT IT IN WHEN WE DID. WE ALWAYS HAD OUR TRUCK REPAIRED AT THE NISSAN DEALER, THEY HAD NUMEROUS OPPORTUNITIES TO TELL US, OR WRITE US. WE HAVE NOT MOVED! THIS IS WRONG AND THE CLASS ACTION LAWSUIT SETTLEMENT IS UNFAIR TO THOSE OF US WHO HAPPENED TO HAVE THE ISSUE AT MILEAGE OVER 100,000. THE JUDGE SHOULD HAVE REQUIRED NISSAN TO WARN US. WE ARE GOING TO HAVE TO PAY $5000 TO HAVE THIS REPAIRED, WE ALREADY PAID $200 DOLLARS IN NEW FLUIDS THINKING THAT WAS THE ISSUE.

THE TRANSMISSION FLUID COOLER IN THE RADIATOR HAS BUSTED CAUSING RADIATOR COOLANT TO GET INSIDE THE TRANSMISSION. WHEN THE COOLANT MIXED WITH THE TRANSMISSION FLUID IT HAS CAUSED CATASTROPHIC DAMAGE TO THE INSIDE OF THE TRANSMISSION (GEARS, ETC.) A COUPLE OF WEEKS AGO I NOTICED THE TRANSMISSION STARTING TO SHIFT MORE AND MORE ABRUPTLY. I DROVE TO WORK AND AT THE END OF MY SHIFT, MY TRUCK WOULD NOT START. I DISCOVERED THE REASON FOR IT NOT STARTING WAS DUE TO THE AUTOMATIC TRANSMISSION FUSE WAS BLOWN. I REPLACED THE FUSE, STARTED THE TRUCK AND THE FUSE BLEW AGAIN. I TOOK IT TO A MECHANIC AND HE DISCOVERED THE ISSUE WITH THE RADIATOR AND TRANSMISSION. THIS IS A RECURRING ISSUE WITH 2005 -2010 PATHFINDER, FRONTIER AND XTERRA OWNERS. WHAT CAN BE DONE TO HOLD NISSAN ACCOUNTABLE FOR A FAULTY PRODUCT THAT THEY ARE OBVIOUSLY AWARE OF BUT WILL NOT CORRECT. THIS IS GOING TO COST ME $3500 - $4500 TO REPAIR

MY RADIATOR HAD FAILED CAUSING TRANSMISSION FLUID TO ENTER THE COOLANT AND COOLANT TO ENTER THE TRANSMISSION. ONCE NISSAN REPLACED THE RADIATOR AND FLUSHED OUT BOTH SYSTEMS, THE TRANSMISSION SEEM TO DRIVE OK, AND THE NISSAN DEALER SAID IT SEEMS TO BE OK. AFTER DRIVING THE VEHICLE FOR A MONTH THE TRANSMISSION HAS DEVELOPED SLIPPAGE DUE TO THE PREVIOUS RADIATOR WITH AN INTERNAL TRANSMISSION COOLER THAT CAUSED INTERNAL DAMAGE TO THE TRANSMISSION. IF NISSAN HAD BUILT THE TRUCK WITH AN EXTERNAL TRANSMISSION COOLER SEPARATE FROM THE RADIATOR, I WOULDN'T HAVE HAD AN ISSUE WITH THE TRANSMISSION ONCE THE RADIATOR FAILED. AS AN ASE CERTIFIED MECHANIC WITH WORKING IN THE INDUSTRY FOR 10 YEARS, ALSO SERVING IN THE MILITARY AS A MAINTENANCE MECHANIC, AND WITH ALL THE DIFFERENT MODELS OF VEHICLES THAT I HAVE OWNED; HAVE I EVER HAD THIS PROBLEM WHERE ONE COMPONENT FAILS THAT WOULD CAUSE ME TO REPLACE A TRANSMISSION. I AM STARTING TO BELIEVE THAT NISSAN IS NOT ANY BETTER THAN OWNING ANY OTHER CAR, AS THE TECHNOLOGY SEEMS TO NOT BE GETTING BETTER BUT MORE COSTLY TO US THE CONSUMERS. THE VEHICLE WAS DRIVIN AT ABOUT 30 MPH WHEN THE TRUCK TEMP GAUGE ELEVATED, AND COOLANT BURPING OUT. I IMMEDIATELY SHUT IT DOWN TO CHECK AND DISCOVER THE ISSUE WAS THE RADIATOR. ONCE TAKEN TO THE SHOP BY TOW TRUCK THE SHOP SAID THE TRANSMISSION FLUID HAD COOLANT INSIDE AND TRANSMISSION FLUID INSIDE THE ENGINE COOLANT AREA AND PASSAGES.

NHTSA ACTION NUMBER 12004. THIS WEEK MY 2007 NISSAN FRONTIER'S TRANSMISSION FAILED AT ROUGHLY 62,000 MILES. I HAD THE VEHICLE TOWED TO MY NEAREST NISSAN DEALER WHERE THEY INFORMED ME THAT IT FAILED DUE TO A LEAK IN THE COOLING SYSTEM CAUSING COOLANT TO LEAK INTO THE TRANSMISSION CAUSING THE FAILURE. THEY ALSO INFORMED ME THAT THIS HAS BEEN SUCH A PROBLEM THAT NISSAN "EXTENDED THE WARRANTY" TO HELP FIX THE PROBLEM. THE ONLY ISSUE IS THAT THE DEDUCTIBLE FOR THE "WARRANTY" IS $3,000! THAT DOES NOT SEEM LIKE MUCH OF A WARRANTY TO ME. I FEEL LIKE NISSAN HAS ADMITTED THE PROBLEM AND IS TRYING TO AVOID A RECALL BY ISSUING THE EXTENDED WARRANTY WITH A DEDUCTIBLE THAT IS MOST LIKELY COVERING A MAJORITY OF THE COST OF THE JOB IF NOT ENTIRELY. SINCE THIS INVESTIGATION IS STILL OPEN I THOUGHT IT ONLY APPROPRIATE TO CONTRIBUTE.
