2007 Nissan Titan Powertrain & Transmission Problems

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.

THE REAR AXLE SEALS ON MY 2007 NISSAN TITAN CONTINUE TO LEAK GEAR OIL. I HAVE REPLACED THE SEALS THREE TIMES INCLUDING PURCHASING AND REPLACING THE ENTIRE AXLE SHAFT, SEAL AND SPACER ASSEMBLY ON THE THIRD TIME. THESE WERE 2 AXLE SHAFT ASSEMBLIES WHICH COST ME OVER $1000. I HAVE ALSO INSTALLED A BREATHER TUBE ON THE REAR AXLE AND INSURED IT IS ALLOWING AIR TO GET IN AND VENT THE REAR AXLE. IT'S BEEN A FEW MONTHS AFTER INSTALLATION AND THE SEALS ARE LEAKING AGAIN. MY REAR BRAKES AND PARKING BRAKE ARE SOAKED WITH OIL AND THE PARKING BRAKE NO LONGER HOLDS THE TRUCK IN PLACE WHEN PARKED ON A INCLINE/DECLINE.

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.

ON TWO SEPARATE OCCASIONS THE LEFT AND RIGHT BACK AXEL SEAL STARTED LEAKING OIL ON TO THE BACK BRAKES AND WHEELS. THE SEALS AND BACK BREAKS HAD TO BE REPLACED BOOTH TIMES WOULD NOT PASS STATE INSPECTION BECAUSE OIL SOAKED BREAK PADS BREAKS HAD REDUCED STOPPING POWER.

I RECENTLY BOUGHT A 2007 NISSAN TITAN AND I LOVE THE TRUCK. I WAS DRIVING ALONG AND I STARTED SMELLING BRAKES BURNING, I PULLED OVER AND MY REAR PASSENGER WHEEL WAS SMOKING. I LOOKED ON THE BACK SIDE AND REAR END DOPE WAS ON THE BACK OF MY WHEEL. THE WHEEL SEAL HAS WENT OUT. COME TO FIND OUT LOOKS LIKE THE REAR DIFFERENTIAL HAS BEEN SEALED UP BEFORE. SO, ITS A PROBLEM WITH THE NISSAN TITAN REAR END SEALS AND DIFFERENTIAL SEAL. IT CREATES A SAFETY HAZARD GETTING ON THE BRAKES. THE WHEEL COULD CATCH ON FIRE. *TR

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

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

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.

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

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

WAS DRIVING DOWN THE ROAD AT 50MPH WENT TO SLOW DOWN AND THERE WHERE NO BRAKES SO FINALLY I PULLED I'VE AND LOOKED AROUND AND OIL WAS DRIPPING OUT OF THE AXLE HOUSING ALMOST A BAD SITUATION. COME TO FIND OUT ON THE NISSAN TITAN TALK FORUM THERE ARE MANY MANY MORE OF THESE LIKE MINE THIS SHOULD DEFIANTLY BE A RECALLED ITEM VERY DANGEROUS. *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

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

MY PASSENGER SIDE REAR AXLE SEAL IS LEAKING. FROM WHAT I HAVE READ, THIS IS AN EXTREMELY BIG PROBLEM ON NISSAN TITAN'S. THE LEAK IS AFFECTING THE FOLLOWING PARTS: - PASSENGER SIDE REAR BRAKE COMPONENTS - PASSENGER SIDE REAR TIRE (SIDEWALL) - ENTIRE REAR AXLE ASSEMBLY. *TR

REAR DIFFERENTIAL IS LEAKING OIL ON PASSENGER AND DRIVER SIDES. THE OIL LEAK HAS THE POTENTIAL TO DETERIORATE MY BRAKES AND CAUSE AN ACCIDENT. *TR
