TAIL PIPE RUSTED OFF AT THE FLANGE BEHIND THE MUFFLER. THE DESIGN OF THE TAILPIPE AND EXHAUST HANGER IS FLAWED.
TL* THE CONTACT OWNS A 2012 NISSAN TITAN. THE CONTACT STATED THAT THE EXHAUST MANIFOLD WAS RUSTED AND CRACKED. THE DEALER WAS NOT CONTACTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED AND DID NOT ASSIST. THE FAILURE MILEAGE WAS 147,000.
NISSAN TITAN HAS A CRACKED MANIFOLDS WHICH LEAKS EXHAUST INTO THE CAB OF THE VECHICLE. APPREANTLY THIS IS A KNOW ISSUE WITH NISSAN AND THE NEED TO GET A REAL FIX NOT A REPLACEMENT BUT A REPLACEMENT THAT WONT HAPPEN AGAIN
EXHAUST MANIFOLD CRACKS: RIGHT SIDE REPLACED AT 78,000 MILES IS CRACKED AGAIN AT 130,000. LEFT SIDE CRACKED AND REPLACED AT 130,000. CONCERNED ABOUT CARBON MONOXIDE LEAKAGE.
CONNECTION USED BETWEEN MUFFLER AND TAILPIPE COMPLETELY RUSTED AWAY LEAVING THE TAILPIPE DANGLING FROM BOTTOM OF TRUCK. THIS IS A MANUFACTURING DESIGN ISSUE IN WHICH ALL NISSAN TITAN TRUCKS SINCE ORIGINAL RELEASE HAD A CONNECTOR PIECE THAT IS NOT GALVANIZED FOR RUST PREVENTION WELDED TO THE BEGINNING OF THE TAILPIPE AND THE END OF THE MUFFLER PIPE EXTENSION. THESE PIECES ARE THEN BOLTED TOGETHER WITH BOLTS THAT AREN'T GALVANIZED. THE CONNECTION PIECES ARE FLANGED SO THEY HOLD WATER AND START RUSTING. THE RUSTING TYPICALLY STARTS TO COMPLETELY RUST THROUGH AFTER THE 36 MONTH WARRANTY IS OVER BUT BEFORE 60 MONTHS. THIS DESIGN HAS NOW BEEN CHANGED ON THE LATEST RELEASE ON NISSAN TITANS (2016 MODELS) NISSAN IS WELL AWARE OF THE ISSUE AND EVEN REIMBURSED ME FOR A FIX OF THE PROBLEM BUT WOULD NOT DOCUMENT IT IN WRITING. THEY ONLY TOOK MY COMPLAINT VIA PHONE, THEN PROMISED TO PAY BACK BY CHECK, AND MADE ME HAVE THE WORK DONE AT MY LOCAL NISSAN DEALER. THIS ISSUE ISN'T BEING REPORTED ONLY BECAUSE MOST TITANS ARE WORK TRUCKS THAT ARE COMMONLY SERVICED BY THE OWNER THEMSELVES. HOWEVER THIS ISSUE CAN CAUSE A TAILPIPE TO FALL OFF ON A HIGHWAY THAT CAN OR EVEN MAY HAVE ALREADY CAUSED ACCIDENTS TO VEHICLES THAT ARE SIMPLY DRIVING BEHIND A NISSAN TITAN. LUCKILY I NOTICED THE HANGING TAILPIPE WHEN I WAS IN A PARKING LOT SO I STRAPPED IT UP TO THE BODY AND SAFELY DROVE IT HOME TO TEMPORARILY FIX TILL I COULD CONTACT NISSAN CORPORATE TO GET THEM TO HELP. I HAVE TO SAY THEY DID FIX THE ISSUE BUT ONLY AFTER I COMPLAINED. THE DEALERSHIP KNEW IMMEDIATELY WHAT THE PROBLEM WAS AND HOW TO FIX BUT ALSO WAS SENSITIVE TO MAKING THIS AN ISSUE AS THEY SEEM TO BE COVERING UP AND JUST HOPING THE OWNERS OF NISSAN TITANS WILL FIX THIS ISSUE THEMSELVES AS WE ARE EVERYDAY US CITIZENS THAT HANDLE PROBLEMS DAILY IN OUR LIVES. THIS ONE NISSAN SHOULD STAND UP TO AND HAVE A PROPER RECALL. *TR
