2007 Nissan Titan Power Train

I have a defective exhaust manifold that’s letting gases in the cab

The rear differential and axle has an inevitable failure with no warning lights or much anything else besides some possible noises! The vent designs are terrible it causes overheating and internal turmoil over time seals start leaking, bearings and internal gears Get weak from over hot /cold repeated cycles allowing moisture to build and accumulate in the 3rd member where it’s supposed to be completely sealed and dry other then gear oil to lube and maintain proper function. My personal and current experience is I’m without my truck, missing work and very . Very thankful that it didn’t lock up on the highway/freeway that I drive too and from work about 85 miles daily! The best part is there’s no fast cost efficient resolution! the differential open carrier with spider gears held in place by a shaft pin and tiny 8 mm bolt that broke causing the pin to slide back and forth (pinball effect) into the ring /pinion, side gears, spider gears untill it either gets jammed in the gears and instantly locks up or slowly fractures away untill gears held by nothing, collide causing catastrophic failure! I Happened to notice the inside of rear wheel wet because when I was exiting the highway I heard a faint sound almost like a bolt or rock or something hit underneath the truck so I took a glance at everything and noticed that wheel grease soaked and a little fluid on the bottom of transfer case.. long story short I drove it approximately 1 mile to a shop there it still sits needing complete different axle and differential or a whole new carrier and all bearings/seals spacers possibly axle shaft don’t know yet and dealership can not get any parts for it!! The parts are obsolete! None! Don’t sell them, don’t make them….. they recommend and can only replace whole unit around 3-5k thousands of dollars I wish I had!! All of the research I’ve done tells me this is a HUGE problem! Theres hundreds of thousands of people that this has happened too! Asking why isn’t there a recall??!

MY REAR DIFFERENTIAL HAS FAILED UNDER NORMAL OPERATING CONDITIONS, ALMOST CAUSING ME TO WRECK. APPARENTLY, THIS IS NOT A NEW ISSUE WITH THESE TRUCKS. I WAS DRIVING 50MPH WHEN THE REAR END MADE A POP AND I LOST THE ABILITY TO DRIVE.

REAR AXLE SEALS LEAKING CAUSING LUBRICANTS TO CAUSE THE REAR BRAKES TO FAIL.

HAD TRANSMISSION SERVICED AND ABOUT 5000 MILES OR LESS LATER TRUCK STARTED HESITATING AND FINALLY STOPPED. INVESTIGATED AND FOUND TRANSMISSION FLUID AND ANTIFREEZE UNDER TRUCK. HAD TOWED TO NEAREST AMMCO STATION AND THEY DIAGNOSED PROBLEM AS ANTIFREEZE IN TRANSMISSION SMELLED BURNED AND SAID A COMPLETE RE-MANUFACTURED TRANSMISSION WAS RECOMMENDED SINCE ALL OF THE TRANSMISSION COMPONENTS HAD BEEN EXPOSED TO THE ANTI-FREEZE AND WERE BURNED OR OVERHEATED. TALKED WITH NISSAN OF GASTONIA NC. AND THEY STATED THEY COULD INSTALL A NEW RE-MANUFACTURED TRANSMISSION AND RADIATOR AND EXTERNAL AFTER MARKET TRANSMISSION FLUID COOLER FOR 5,100 DOLLARS WITH A 12 MONTH 12,000 MILE WARRANTY. THEY SAID THEY HAD A LARGE NUMBER OF FRONTIER, XTERRA, AND PATHFINDER PROBLEMS WITH THE INTERNAL TRANSMISSION COOLER INSIDE THE RADIATOR FAILING ALLOWING ANTI-FREEZE TO LEAK INTO THE TRANSMISSION AND DESTROYING IT. THEY SAID THEY HAD NOT SEEN THE SAME PROBLEM WITH THE TITANS ANS ARMADAS. THEY HAD A CAMPAIGN TO HELP OWNERS OF THE OTHER MODELS BUT NOT THE TITANS OR ARMADAS. THE SERVICE MANAGER FOR NISSAN OF GASTONIA SAID THEY COULD LOOK AT MY TRUCK BUT THERE WOULD BE A DIAGNOSE FEE IF I DIDN'T LET THEM DO THE WORK. THE SERVICE MANAGER AT AMMCO SAID HE WOULD MATCH NISSAN'S OFFER AND GIVE ME A 36 MONTH UNLIMITED MILEAGE WARRANTY COVERING PARTS AND LABOR, SO I WENT WITH AMMCO. THE SERVICE MANAGER AT AMMCO STATED HE HAD NUMEROUS TITAN AND ARMADA VEHICLES COME INTO HIS SHOP AS WELL AS THE OTHER MODELS WITH THE SAME PROBLEM. THE INTERNAL TRANS/COOLER LETS ANTI-FREEZE LEAK INTO THE TRANSMISSION AND IT FRIES THEM. I JUST HAD MY TRANSMISSION SERVICED AND THE RADIATOR FLUSHED AND FILLED. MY 2007 TITAN ONLY HAS 65000 MILES ON IT, AND IF NISSAN KNEW THEY WERE HAVING PROBLEMS THEY COULD HAVE WARNED ME AND I WOULD HAVE HAD THE RADIATOR CHANGED OUT. THIS IS REALLY BAD BUSINESS IN MY OPINION.

REPLACE PASSANGER SIDE AXLE SEAL AT 94000 MILES. NOW I HAVE A DRIVER SIDE AXLE SEAL LEAK AT 105000 MILES. SEEMS TO BE A PROBLEM AFTER LOOKING AROUND ON THE INTERNET.

REAR AXLE SEALS LEAKING ALL OVER BREAK SHOES (COULD CAUSE FIRE) FAILED SEALS GROVED OUT AXLES. NEED TO REPLACE SEALS AND AXLES.

MY 2007 NISSAN TITAN LE 4X4 HAS EXPERIENCED (3) REAR AXLE SHAFT SEAL FAILURES IN ADDITION TO (3) FRONT AXLE SHAFT SEAL FAILURES ALL WITHIN ABOUT 20,000 MILES OF EACH OTHER. THE REAR AXLE SEAL FAILURES ARE A SAFETY CONCERN TO ME. THE DIFFERENTIAL FLUID LEAKS DIRECTLY ONTO THE REAR BRAKE ROTORS WHICH CAUSES A REDUCTION IN BRAKING ABILITY. IT IS CLEAR AFTER SOME RESEARCH THAT THIS IS A VERY COMMON ISSUE WITH MULTIPLE MODEL YEAR NISSAN TITAN TRUCKS. NISSAN SHOULD ADDRESS THIS ISSUE AND OFFER A PERMANENT SOLUTION SO WE WOULD NOT BE FACED WITH THIS SAFETY ISSUE IN THE FUTURE. MY FIRST REAR AXLE SHAFT SEAL FAILURE OCCURRED AT 56,672 MILES ON 6/9/14. I HAD ANOTHER FAIL AT 62,930 ON 11/4/14. THE THIRD ON 8/23/15 AT 75,000 MILES. THE FRONT AXLE SHAFT SEAL FAILURES OCCURRED AT 53,139 ON 3/20/14, AGAIN IN OCTOBER 2014 (MILEAGE NOT AVAILABLE), AND THEN AT 65,105 MILES ON 1/21/15. BTW, I HAVE TRIED SUBMITTING THIS TWICE BEFORE AND GOTTEN ERRORS SO I APOLOGIZE IF THIS HAS ACTUALLY WORKED ALL 3 TIMES.

THIS IS NOW MY 5TH REPLACEMENT AXLE SEAL AND OR BEARING, I CANT BELIEVE NISSAN HASN'T BEEN MADE TO CORRECT THIS ONGOING ISSUE, YES THEY REPLACED THE FIRST ONE BUT IT HAS BEEN MINE TO REPLACE EVER SINCE. *TR

WE PURCHASED THE NISSAN TITAN NEW IN 2007. THE FIRST REPAIR FOR THE REAR DIFFERENTIAL (AXLE BEARING WAS LEAKING) WAS ON 1/13/2010 34,617 MILES. THE SECOND REPAIR FOR THE SAME ISSUE WAS 3/29/2012 WITH 79,010 MILES. THE VEHICLE HAS NOW AGAIN BEEN DIAGNOSED WITH THE SAME REAR DIFFERENTIAL PROBLEM AT 115,000 MILES. THIS HAS BEEN A CONSISTENT RECURRING ISSUE EVERY 35 - 40,000 MILES AND IT IS NOW RECOMMENDED THAT A FULL REPLACEMENT OF THE REAR DIFFERENTIAL IS NEEDED TO FULLY FIX THE PROBLEM. THIS IS A HUGE PROBLEM THAT NISSAN NEEDS TO ADDRESS FROM BOTH A SAFETY PERSPECTIVE SHOULD THE VEHICLE LOCK UP AND THE EXPENSIVE REPAIRS. *TR

REAR AXLE SEAL HAS A LEAK. THIS LEAK IS CAUSED TO INCREDIBLY POOR VENTILATION OF THE REAR DIFFERENTIAL. THE CHECK VALVE ALLOWS WATER INTO THE CASE AND DOES NOT ALLOW FOR PROPER VENTILATION. THIS, IN TURN, CAUSES OVERHEATING AND SEALS TO FAIL. THIS REPAIR HAS HAPPENED ON THIS TRUCK FOR THE SECOND TIME NOW, WITH NO ACKNOWLEDGEMENT FORM THE MANUFACTURER. *TR

AXEL SEALS STARTED LEAKING IN 2010,THE TRUCK WAS TAKEN TO THE DEALERSHIP FOR REPAIR COST WAS APPROXIMATELY 1000 DOLLARS MAY OF 2012 WAS TOLD AXEL SEALS WHERE LEAKING AGAIN AND THEY HAVE NOT BEEN FIXED. *TR

DRIVING ALONG BELOW HIGHWAY SPEED IN 4 WHEEL DRIVE ON A STEEP UPHILL ON SNOWY ROAD. I LOST 4 WHEEL DRIVE AND CAUSED THE REAR WHEELS TO START SPINNING AND SENDING THE VEHICLE SIDE WAYS. RECOVERED BY LETTING OFF GAS. LOOK UNDER TRUCK TO FIND THE DRIVER SIDE AXLE OUT OF THE TRANSFER CASE. COME TO FIND OUT THIS IS A HUGE ISSUE FROM MANUFACTURER FROM 04-07. SOMEBODY NEED TO GET SERIOUSLY HURT FOR ACTION ON THIS MATTER? *TR

REAR AXLE SEAL LEAKING, AGAIN. SAME SEAL WAS REPLACED 2YRS AGO. COULD BE SAFETY HAZARD IF REAR AXLE FLUID GETS ON BRAKE ROTOR. *TR

REAR DIFFERENTIAL AXLE SEALS ARE BAD AND LEAKING REAR DIFFERENTIAL FLUID ON EMERGENCY AND REAR BRAKE PADS. *TR

YET ANOTHER TITAN WITH LEAKING REAR SEALS. IF IT LEAKS ENOUGH THE BRAKES GET COVERED IN DIFF FLUID AND THE REAR END BLOW UP. *TR

REAR AXLE SEAL LEAKED ON DRIVERS SIDE AT 66,000 MILES. GEAR OIL ALL OVER BRAKES WHICH IS A MAJOR SAFETY CONCERN. NO MODIFICATIONS - TRUCK IS FULL STOCK. NISSAN DEALER DATABASE REVEALS THIS ISSUE HAPPENED ALSO AT 29,000 MILES AND ENTIRE RFD WAS REPLACED UNDER WARRANTY FOR PREVIOUS OWNER. NOW HAPPENS AGAIN AT 66,000 MILES. I AM TOLD THERE IS A TSB FOR THIS ISSUE, BUT SINCE VEHICLE IS OUT OF WARRANTY(6,000 MILES AGO) THAT THIS IS MY PROBLEM. DEALER TOLD ME THAT THIS PROBLEM COULD VERY WELL HAVE BEEN GOING ON WITHOUT MY NOTICE FOR LONGER THAN 6,000 MILES. A LITTLE RESEARCH REVEALS THIS TO BE A VERY COMMON PROBLEM WITH THESE TRUCKS. NISSAN NEEDS TO ACKNOWLEDGE THAT THEY HAVE A FAULTY DESIGN IN THE RFD, AND THEY NEED TO STEP UP AND ISSUE A RECALL FOR THIS ISSUE DUE TO IT BEING A MAJOR SAFETY CONCERN! *KB

PASSENGER SIDE REAR AXLE SEAL FAILED. FLUID IS LEAKING ON THE BACK SIDE OF BRAKE SHIELD ON TO WHEEL. MAY BE LEAKING INSIDE THE ROTOR DRUM ON THE EMERGENCY BRAKE ALSO. 4X4 OEM E-LOCKER ON REAR DIFFERENTIAL OEM WHEELS AND TIRES DIFFERENTIAL FLUID CHANGED TWICE ORIGINAL OWNER *TT

2007 NISSAN TITAN REAR DIFFERENTIAL FAILED. I NOTICED A THUNK WHEN COMING TO A STOP OR STARTING UP FROM A STOP. UPON DECELERATION THERE WOULD BE A THUNK THUNK THUNK. TEMPO WOULD INCREASE OR DECREASE IN RELATION TO SPEED. I TURNED A CORNER, FELT AND HEARD A VERY SIGNIFICANT CLUNK/BANG, FELT LIKE I ROLLED OVER A BOULDER, AS I PROCEEDED FOR ANOTHER 50 YDS, THE THUNK WAS HARD ENOUGH TO FEEL THROUGH THE VEHICLE AND LOUD ENOUGH TO HEAR FROM OUTSIDE THE VEHICLE AS EVIDENCED BY THE STARES I GOT AS I CAME TO A STOP. TOWED IT TO SHEEHY NISSAN IN MANASSAS, VA, THEY CONFIRMED IT WAS THE REAR DIFF AND REPLACED IT UNDER WARRANTY. MILEAGE WAS 42,828. *TR

THE REAR AXLE SEALS LEAK AND THE REAR DIFFERENTIAL FLUID IS ALL OVER THE BRAKES. THIS NEEDS TO BE RECALLED AS IT IS A KNOWN DEFECT WITH THIS VEHICLE AND HAS BEEN REPORTED MANY TIMES. *TT

AT AROUND 60,000 MILES BOTH MY REAR SEALS AND PINION SEAL BLEW DUE TO A BAD AIR VALVE OR INFERER SEALS, CAUSEING THE REAR BRAKES TO PREMATURLY FAIL, DUE TO THE OIL THAT HAD BEEN SPILLING ON TO THEM, THIS SHOULD NOT HAVE ACCURED ON A VEHICLE WITH MINAMAL MILES AND NO TOWING OR HAULING ... *TT

I NOTICED A WHINING NOSE FROM 45 TO 70 MPH. IT GOT REAL LOUD AD 60-65 MPH. MY TITAN IS REGULARLY SERVICED WITH DIFFERENTIAL FLUID CHANGES, AND ALL MAINTENANCE. THE TRUCK HAS 112,000 MILES ON IT. I WAS JUST TOLD THAT THEY NEED TO REPLACE THE REAR DIFFERENTIAL ON THE TRUCK, AT A COST OF $2448 PLUS TAX ON A VEHICLE THAT IS VERY WELL MAINTAINED AND TAKEN CARE OF. NO EXCUSE FOR IT, AND RIDICULOUS. *TR

FRONT DIFFERENTIAL OF 4WD FAILED. FACTORY DEFECT THAT NISSAN REFUSED TO STAND BEHIND. AXLE BECAME UNCLIPPED WITHOUT ANY ABUSE OR IMPACT. UNDETECTED COULD RESULT IN SEIZURE AND FATAL ACCIDENT. UPDATED 02/14/11 *BF

WHILE DRIVING ON FLAT ROAD UNDER NORMAL ROAD CONDITIONS I HEARD A LOUD THUMP FROM THE REAR OF THE TRUCK FOLLOWED BY A SEVERAL MORE INTERMITTENT THUMPS. THE TRUCK STILL DROVE, BUT WITH THE THUMPING. UPON INSPECTION I DISCOVERED THAT THE CROSS SHAFT FOR THE SPIDER GEAR SLIPPED OUT AND GOT IN BETWEEN THE PINION AND RING GEAR CAUSING IT TO BIND. IT BROKE SEVERAL TEETH OFF OF THE RING GEAR, DAMAGED THE CROSS SHAFT AND MARRED THE PINION GEAR. *TR

REAR AXLE SEAL LIKE ON 2007 NISSAN TITAN. *TR
