2006 Nissan Titan Engine

My vehicle, which I bought used with about 140,000 miles on it had cracked exhaust manifolds, which I replaced. Both were cracked and one actually fell to pieces when unbolted. One replacement cracked after about 15,000 miles, but was able to have it braised. Now, at about 180,000 miles they a spewing carbon monoxide into the cab again. This is a serious health and safety issue, and from checking Titan club web sites, it seems to be a widespread issue. I DO NOT DRIVE OFF ROAD OR SUBJECT THE TRUCK TO ABNORMAL DRIVING CONDITIONS. I appreciate your time and consideration. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

TL* THE CONTACT OWNS A 2006 NISSAN TITAN. THE CONTACT STATED WHILE IDLING, THE FRONT OF VEHICLE CAUGHT FIRE. THE CONTACT STATED NO WARNING LIGHT WAS ILLUMINATED. THE CONTACT WAS ABLE TO EXTINGUISH THE VEHICLE WITH A FIRE HYDRANT HIS NEIGHBOR PROVIDED AT THE MOMENT. A FIRE DEPARTMENT DID FILE A REPORT. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. A DEALER WAS NOT CONTACTED. THE VIN WAS ASSOCIATED TO NHTSA CAMPAIGN NUMBER: 10V517000 (ENGINE AND ENGINE COOLING). THE MANUFACTURER HAD NOT BEEN INFORMED OF FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 120,000.

I THINK IT WAS IN 2009 WHEN I TOOK MY VEHICLE TO NISSAN TO CHECK ENGINE LIGHT AND LIGHT SMOKE OUT OF EXHAUST. RAN DIAGNOSTIC AND FOUND OUT THAT CATALYTIC CONVERTERS BROKE UP AND BROKEN MATERIAL WENT BACK (SUCKBACK) INTO ENGINE AND DAMAGED PISTON RINGS WHICH WAS CAUSING IT TO SMOKE. TOLD ME I NEEDED TO REPLACE ENGINE CAUSE IT WAS PRETTY MUCH NO GOOD. THIS TRUCK WAS 3 YRS. OLD AT THE TIME. WARRANTY WAS OUT AND WAS AND COST ME A FORTUNE TO REPLACE ENGINE AND EXHAUST SYSTEM. I HAD NO IDEA TIL NOW HOW MANY 2006 TITAN OWNERS HAVE HAD THE SAME ISSUE. THIS HAS TO BE RECALLED.

EXHAUST MANIFOLDS LEFT AND RIGHT CRACKED AND LEAKING LESS THAN 1 MOS OUT OF WARRENTY NISSAN REFUSED ANY ASSISTANCE. I WAS A NISSAN PARTS MGR FOR 50 YRS NO CONSIDERATION. WHEN MY WIFE NEEDED A NEW CAR FOR HER 2001 SENTRA WE PURCHASED A MAZDA CX5 INSTEAD OF A ROUGE

MY ONLY COMPLAINT WOULD BE WHY HASN'T THEIR BEEN A RECALL ON ANY TITANS THAT ARE HAVING CRACKED EXHAUST MANIFOLDS, WHICH CAUSE CHECK ENGINE LIGHT AND VERY EXPENSIVE REPAIRS.

EXHAUST MANIFOLDS CRACKED LEAKING ASKED NISSAN FOR HELP WAS REJECTED HAD MANIFOLDS REPLACED WITH AFTERMARKET PARTS WHICH COST 1/3 THE PRICE OF NISSAN WORK DONE BY A MASTER NISSAN TECH. *JS

THE EXHAUST MANIFOLDS CRACK AND CAUSE ENGINE WARNING LIGHT. ONLY FIX IS TO RE PLACE MANIFOLDS. MANIFOLDS ARE MANUFACTURE DEFECTIVE. COST TO REPLACE IS OVER $2000.00 NISSAN STATED NO RECALL.

CRACKED EXHAUST MANIFOLD HAS BEEN NOTED, AND/OR.POSSIBLE MALFUNCTION OF CATALYTIC CONVERTERS WELDED TO MANIFOLDS. 118,500 MILES. REPLACEMENT MANIFOLDS/CATS COST IS VERY EXPENSIVE AND LABOR INTENSIVE. SO-CALLED "COMMON PROBLEM" WITH TITANS. IMO, THIS PROBLEM MAY POSSIBLY SEND CO2 TO PASSENGERS IF NOT CORRECTED, NOT TO MENTION POOR VEHICLE PERFORMANCE AND POSSIBLE SEVERE ENGINE DAMAGE IF NOT CORRECTED. NISSAN SHOULD CERTAINLY INITIATE A RECALL ON THIS DANGEROUS PROBLEM.

MY HUSBAND WENT TO SEE HIS MOM AND ABOUT 20 MILES FROM OUR HOME APPROXIMATELY 5 MILES AWAY FROM DESTINATION THE TRUCK STARTED VIBRATING AND SPUTTERING THEN THE ENGINE STARTED MAKING A LOUD CLANKING NOISE THEN SHUT OF MECHANIC SAID THE ENGINE WAS BLOWN PRIOR TO ALL THIS ENGINE STARTED CUTTING OUT WHILE DRIVING ON THE FREEWAY WHEN WE WENT TO DO OUR SMOG CHECK IT FAILED BECAUSE OF THE CATALYTIC CONVERTERS HAD TO BE REPLACED DUE TO THE FACT THAT THE HONEYCOMB WAS COMPLETELY GONE. *TR

TL* THE CONTACT OWNS A 2006 NISSAN TITAN. THE CONTACT STATED THAT THE PASSENGER SIDE MANIFOLD WAS CRACKED. A LOUD EXHAUST NOISE COULD BE HEARD FROM THE FRONT PASSENGER SIDE OF THE VEHICLE. THE FAILURE EXISTED FOR THE PAST TWO YEARS. AN INDEPENDENT MECHANIC STATED THAT THE EXHAUST MANIFOLD WAS CRACKED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED AND THE MANUFACTURER WAS NOT NOTIFIED. THE VIN WAS UNAVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 117,000.

THE EXHAUST MANIFOLDS CRACK AND CAUSE EMISSIONS LEAKS. *TR

NOTICED UPON STARTING THE VEHICLE, A CLICKING SOUND WHICH BECAME LOUDER WHEN DRIVING. VEHICLE WAS UNDER WARRANTY. THE DEALER STATED THE EXHAUST MANIFOLD WAS CRACKED. THEY FIXED IT. SHORTLY AFTER THE OTHER EXHAUST MANIFOLD CRACKED AND THEY FIXED THAT AS WELL. SINCE THEN, THE WARRANTY HAS EXPIRED AND EITHER ONE OR BOTH EXHAUST MANIFOLDS HAVE CRACKED AGAIN. I WAS TOLD IT WAS GOING TO COST LITERALLY THOUSANDS OF DOLLARS TO REPAIR. UNFORTUNATELY, I CAN NOT AFFORD TO REPAIR THE VEHICLE. I WAS UPSET, BUT WAS WILLING TO ACCEPT THE SITUATION, UNTIL ONE MORNING I GOT A STRONG SMELL OF EXHAUST IN THE CAB OF THE VEHICLE. BEING A MECHANIC, I HAD MY HUNCHES. IT DOESN'T HAPPEN ALL THE TIME, BUT ON OCCASION I GET EXHAUST EMISSION IN THE VEHICLE. I HAVE ALSO RECENTLY FOUND ONLINE THAT THERE ARE AN ABUNDANT AMOUNT OF OTHER NISSAN TITAN OWNERS COMPLAINING OF THE SAME THING. THERE IS ALSO THE POSSIBILITY THAT IF THE LEAK IS AROUND ANY WIRING, THE HOT GAS MAY CAUSE THE WIRING TO MELT CAUSING A POSSIBLE ENGINE FIRE. THAT OF COURSE IS JUST AN EDUCATED OPINION. HOW MANY MORE EXHAUST MANIFOLDS HAVE TO CRACK BEFORE NISSAN WILL ADMIT THEY ARE A DEFECTIVE DESIGN. IS IT ABOUT THE MONEY TO RECALL THE VEHICLE OR IS IT ABOUT SAFETY AFTER ALL? IN ADDITION, I WOULD HAVE COMPLETED THIS FORM A LOT SOONER, BUT I WAS JUST RECENTLY INFORMED ABOUT IT. THE VEHICLE OBVIOUSLY HAS MORE WEAR AND TEAR AND MORE MILEAGE, BUT THE FACT REMAINS THAT THIS HAPPENED MANY MILES AGO. THANK YOU FOR TAKING TIME TO READ MY LETTER. *TR

CRACK ON THE EXHAUST MANIFOLD ON PASSENGER SIDE. *TR

WAS TOLD DURING YEARLY STATE VEHICLE INSPECTION THAT IT WOULD NOT PASS DUE TO CRACKED EXHAUST MANIFOLDS ON BOTH THE DRIVER'S AND PASSENGER'S SIDE. I WAS 19 DAYS OUT OF WARRANTY, BUT ALMOST 23,000 MILES UNDER. THIS IS A PLEASURE USE TRUCK THAT AVERAGES ROUGHLY 7000 MILES PER YEAR AND SOMETIMES ISN'T DRIVEN FOR WEEKS. I HAVE HAD IT SERVICED BY THE DEALERSHIP FROM THE DAY I BOUGHT IT. SOUGHT ASSISTANCE FROM NISSAN AMERICA BUT WAS DECLINED WITHOUT EXPLANATION. IT'S CLEAR THAT BOTH DID NOT CRACK AFTER THE EXPIRATION DATE OF THE WARRANTY. IT IS ALSO CLEAR, BASED ON ONLY A FEW MINUTES OF INTERNET RESEARCH, THAT THIS IS A WIDESPREAD AND WELL PUBLISHED PROBLEM. THE FACT THAT IT WON'T PASS A STATE INSPECTION SPEAKS TO THE DANGER OF SERIOUS PERSONAL INJURY DUE TO EXHAUST FUMES ENTERING THE CABIN. WHY HAVE YOU NOT FORCED A RECALL? THE MANIFOLDS BEING REPLACED HAVE NO DESIGN IMPROVEMENTS TO PREVENT FUTURE FAILURES. NISSAN NEEDS TO BE FORCED TO CORRECT THEIR DESIGN ISSUES. REPLACING FAILED PARTS WITH IDENTICAL PARTS, THAT ARE SURE TO FAIL, IS NOTHING MORE THAN RETALIATION FOR BEING FORCED TO HONOR ANY SORT OF WARRANTY AND A "GOTCHA" TO THE CONSUMER. *TR

TL* THE CONTACT OWNS A 2006 NISSAN TITAN. THE CONTACT STATED THAT THE ODOR OF EXHAUST WAS PRESENT INSIDE THE CABIN OF THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHO DIAGNOSED THAT THE PROBLEM WAS DUE TO A CRACKED EXHAUST MANIFOLD. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE PROBLEM. THE FAILURE MILEAGE WAS 50,000.

TL* THE CONTACT OWNS A 2006 NISSAN TITAN. THE CONTACT STATED THAT AN ABNORMAL NOISE EMITTED FROM THE EXHAUST SYSTEM. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION WHERE THE CONTACT WAS ADVISED THAT THE EXHAUST MANIFOLD WAS CRACKED DUE TO DEFECTIVE MATERIAL. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 75,000 AND THE CURRENT MILEAGE WAS 85,000.

TL* THE CONTACT OWNS A 2006 NISSAN TITAN. THE CONTACT WAS DRIVING APPROXIMATELY 55 MPH WHEN THE ENGINE EXHIBITED SEVERE HESITATION WITHOUT WARNING. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER FOR DIAGNOSIS, WHO STATED THAT THE EXHAUST MANIFOLD WAS FRACTURED ON BOTH SIDES. THE VEHICLE WAS IN THE PROCESS OF BEING REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE DEFECT. THE APPROXIMATE FAILURE MILEAGE WAS 150,000. THE VIN WAS UNAVAILABLE.

BOTH PASSENGER AND DRIVER SIDE EXHAUST MANIFOLDS ARE CRACKED AND EXHAUST FUMES ARE ENTERING CAB WHILE DRIVING CAUSING ENGINE CHECK LIGHT TO STAY ON AND ENGINE RUNNING ROUGH. *TR

MY 2006 NISSAN TITAN WAS TAKEN IN FOR RECALLS. UPON COMPLETION OF THE WORK, WHICH WAS POORLY PERFORMED, I WAS NOTIFIED THAT BOTH OF MY MANIFOLDS WERE CRACKED AND WOULD NEED TO BE REPLACED WHICH WOULD COST ME OVER $2,000 BUT THE DEALER WOULD CUT ME A DEAL FOR $1,700 IF I WANTED TO DO IT RIGHT AWAY AND THEY ALSO THREATENED ME WITH THE FACT THAT I WOULD NOT PASS MY SMOG SO I HAD TO DO IT NOW. I DECLINED AS I COULD NOT AFFORD REPAIRS LIKE THAT. AFTER A SHORT SEARCH ONLINE I FOUND THAT THIS WAS A REGULAR ISSUE WITH TITANS BUT WAS NOT SUBMITTED FOR A RECALL. I HAVE ALSO SENT A COMPLAINT TO NISSAN. I AM QUITE DISAPPOINTED WITH THIS ISSUE AS WELL AS THE LACK OF SERVICE I HAVE RECEIVED FROM THE DEALER. MY FAMILY AND I HAVE ALWAYS BEEN STRONG SUPPORTERS OF NISSAN AND OWN MANY OF THEIR VEHICLES AND HAVE NEVER HAD ISSUES LIKE THIS THAT HAVE NOT BEEN ABLE TO BE RESOLVED. I WILL CONTINUE TO BUY NISSANS BUT HOPE THAT THIS WILL BE REVIEWED AND CLAIMED AS A RECALL. I CANNOT AFFORD THE REPAIRS AS MY HUSBAND AND I ARE BOTH CURRENTLY UNEMPLOYED WITH 4 CHILDREN AND THIS IS OUR ONLY VEHICLE WHICH WE CAN NO LONGER DRIVE BECAUSE WE CANNOT HAVE IT SMOGGED TO RENEW REGISTRATION. THERE IS NO DOUBT IN MY MIND THAT THE MANIFOLDS HAD BEEN CRACKED FOR SOME TIME PRIOR TO THE VISIT TO THE DEALER. WE HAD ALWAYS TAKEN OUR TRUCK TO THE DEALER BECAUSE WE HAD PURCHASED A GOLD PACKAGE FOR MAINTENANCE AND I HAD COMPLAINED ABOUT NOISE BEFORE AND THEY COULD NEVER FIND A PROBLEM. IT FIGURES THAT AS SOON AS IT IS OUT OF WARRANTY THEY WOULD MAGICALLY FIND THE ISSUE. *TR

TL* THE CONTACT OWNS A 2006 NISSAN TITAN. THE CONTACT STATED THAT UPON INSPECTION, IT WAS FOUND THAT EXHAUST MANIFOLD WAS CRACKED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 80,025.

TICKING NOISE FROM ENGINE AREA ESPECIALLY UNDER MODERATE ACCELERATION, DEALER INSPECTED AND SAID MY EXHAUST MANIFOLDS ARE CRACKED AND WOULD COST 3K TO FIX . NISSAN CUSTOMER RELATIONS REFUSES TO HELP IN ANY WAY EVEN THOUGH MY TRUCK IS ONLY 4000 MILES PAST MILEAGE LIMIT. THIS IS A KNOWN ISSUE THAT IS A SAFETY HAZARD (EXHAUST FUMES CAN ENTER CAB) AND NISSAN REFUSES TO TAKE ANY RESPONSIBILITY. *TR

HAVE TAKEN IT TO TWO DIFFERENT REPAIR SHOPS AND HAVE BOTH (DRIVERS/PASSENGER SIDE) EXHAUST MANIFOLD ARE CRACKED. HAVE GONE TO NISSAN FOR THE REPAIRS .NISSAN HAS STATED THAT ITS A KNOWN ISSUE ON NISSAN TITANS FOR THE YEARS OF 2004-2007 BUT WON'T REPLACE IT. WAS QUOTED FOR THE REPAIR OF $3,000. ITS JUST OUT OF THE MILES ON THE 80K/8YEAR EMISSIONS WARRANTY, BUT STILL TIME FRAME.
