Problems with 2006 Nissan Titan POWER TRAIN

Overheated, engine would not start, transmission would not shift to go mostly sluggish. this is my 3rd time titan overheated, had to be towed.

My truck has been showing p0335 code issues, which is crankshaft sensor, which has been replaced, my rpm's jump/sputter but the truck stars & runs but feels like its running rough, also i forgot to mention that my dashboards "slip" light remains on... and the biggest problem with it is that, no "professionals" seem to know what it is, nor have they been able to fogure it out as of yet.

Transmission has been stuck in 4th gear while in drive. it. will switch into park, reverse and neutral. when the truck is put on the computer there are no error codes showing that would require repair therefore nissan refuses to submit any documentation higher to address this issue with this standard transmission in all of their vehicles. on a side note, i've had 2 other nissans with a central variable transmission that have all done this as well. i've since been able to get rid of those vehicles, but i am stuck with this one.

Radiator fluid mixing with transmission fluid via internal cooler in radiator causing vehicle to stop moving although motor functioning properly.

Rear differential is leaking gear oil out of both ends of my rwd truck. contacted nissan dealer and they referred me to nissan consumer affairs. filed a claim and was told that the vehicle is out of manufacturers warranty so they would not assist with repair even though this is a known issue with nissan titan trucks, particularly between models years 2004-2006. i have never towed with this truck and have changed the gear oil frequently. also, i have replaced the breather periodically as well. now the fluid is flowing out when vehicle is stationary.

I drove my 2006 nissan titan le to mcdonald's on elk street which is like 5 miles away from my house when you got food came back to my house which is 1700 swanson drive space 43 when inside came back out radiator blew out the bottom replaced radiator and then transmission started going out electrical units relays going out replaced but still truck is acting up really bad i have replaced the radiator transmission bracket tons and tons of fluids a bunch of electrical fuses really tired of working on my truck transmission is going out and i don't feel like i should have to pay for this problem when it all occurred at one time i have this trucks financed i still owe $17,000 on it and it barely runs i would like to proceed on maybe figuring out a way to help me get a new transmission or getting a different vehicle.

After many, many hours of research online to find a recall on the notorious rear end axle problem with the 2004, 2005, and some 2006 nissan titan's there is literally thousands of people with the same problem i am having and nissan has yet to put a recall out due to the poor design of their rear ends in these pick-ups. the problem is the rear axle seals going bad. the problem starts at the top of the rear end with the ventilation system. the ventilation system allows moisture and water to enter the rear end assembly which causes the axle seals to leak which then in turns gear oil leaking all over the rear brakes, which in turn leaks on to the highway. the first set of seals cost me almost $1,200 i am on my 3rd set of seals, and they are leaking again. i have owned the truck for 3 years and the vehicle has 136,xxx on it. the first set of seals went at under 20,000 miles. this is a serious problem due to the fact of the rear end gear oil leaking onto the rear brakes and our highways. there needs to be something done about a recall on these rear ends of these vehicles, before someone's life is taken unexpectedly.

I was alerted that my 2006 nissan titan needed to have the front differential replaced as there was "looseness" and fluid leaking. i was told that this was not repairable and needed to be replaced. failure to do so could cause the front differential to lock up, causing possible sudden stopping and possible loss of control.

On 05/22/2015, traveling on interstate highway at or near posted speed in mild sunny weather. the truck just shut off in lane of traffic. there was no hesitation, noise, alarm, warning lights just shut down. there was no power steering or power brakes. pulled vehicle over to rh shoulder and tried to restart it with out success.on 05/18/2015, i had the truck serviced and inspected at a nissan dealership in anticipation of this road trip. the truck passed dealer inspection. i had the truck towed to a nissan dealer service center and after several days the dealer told me the ecm had failed and shorted out the ignition switch. the repair bill was a little over $1400. i am not objecting to the cost of repair....i am concerned about the truck just stopping on the highway without warning. if this breakdown would have happened in the middle or driving lanes of a nearby freeway, or on a steep incline with turns the results may have been very bad. the dealership said the short and failure of the ecm were a result of a leak in the exhaust system (same one that passed inspection) and heat shorted the wiring harness. i feel the wiring harness may be too close to the heat of the exhaust system and could have been isolated as not to cause failure. updated 8/31/15*cn updated 10/23/2017*cn

While traveling at 80 mph i felt an odd shake on my titan. i exited the freeway and got out of the vehicle. the rear driver side was smoking. i noticed gear oil leaking out all over the brakes and tire. i ended up needing to replace the axle, seal,bearing,backing plate and abs sensor. $1300.00 and 3 days later it is back in the shop. leaking gear oil from the same place. waiting to hear from mechanic what i need to do next. *tr

Both rear axel seals leaking causing oil to seep onto brakes. this is the second occurrence. *tr

Rear end axle seals are leaking, after looking into this and several hours i found i could be caused from the axle vent not working properly, this causes the rear seals to be pushed out and fluid to leak onto the brakes, seems to be a huge problem and safety concern, i was pulling a small trailer at the time and nearly avoided a car that pulled out in front of me. *tr

Leaking rear axle seal. *tr

Front axle failure. *tr

Rear differential seals leaked on brake assemblies. gear oil was present on brake assemblies, wheels and tires. i replaced left and right side differential seals and bearings. an allignment was necessary and was performed. *tr

Rear axel passenger and driver leaking oil, discovered during routine differential oil change. *js

While driving at 45 mph transmission drops out of gear and truck engine nearly red lines. was unable to get completely off the road. after sitting for a few minutes was able to move the truck a few feet to get completely out of traffic. had vehicle towed to nissan dealer where they informed me that i had an intermix of coolant and transmission fluid. they stated that this was a common problem that they see and that nissan extended the warranty to 80,000 miles but i am not covered. they quoted me $8700 to repair. spoke to a few transmission shops and they all indicated that they encourage their nissan clients to bypass the internal tranny cooler in the radiator with an external on when they reach 80,000 miles. they said the cost to do this is less than $300.00. nissan knows of this and even lost a class action suit but has never informed anyone. for a $300 fix i am now out a truck and or $9000.00!!!! way to go nissan!! *tr

Cracked exhaust manifolds. both at the same time. *tr

Rear axle seals leaking differential fluid behind wheels . can be a saftey issue fluid gets on brakes therefore making the brakes unable to stop properly . please fix issue this is a very dangerous situation. *tr

Rear end locked up and had to be replaced. over the years, the rear seals would constantly leak and were replaced multiple times and was usually brought to my attention during oil changes/inspections. i guess they didnt catch it leaking and caused my rear end to lock up which was very dangerous and could have caused a major accident. i was heading to work around 4-5 am in the morning and all my lights on my truck came on kind of felt like i blew a tire and started pulling very hard. i was able to get off the road rather quickly and had it towed. i know plenty of people that have had this issues with the early model nissan titans. besides that though i have been pleased with my titan. i have over 500k miles on it currently. fyi this happened years back but i was reading a forum that we should try to get this recalled and it did cost me alot to have the rear end fixed.

Developed a vibration in the rear end, then noticed leaking oil at the passenger side axle. brought it to the dealer and they said i needed a whole new rear end assembly to the tune of $5600. said they had a "bulletin" regarding this issue! what gives why isn't this a recall? *tr

Traveling 20 to 25 mph, up a hill, in 4 wheel drive road conditions when there was a loud "bang". the rear of the vehicle immediately shifted to the right, striking a tree. never would you expect a vehicle to brake in such a way as to throw you into oncoming traffic. i believe that this defect should be immediately investigated and a recall issued. dealer service department determined that the front differential and transfer case had to be replaced due to catastrophic failure. the front axle had backed out resulting in fluid leaking out. i was told that this was a known defect that had been redesigned. *tr

Tl* the contact owns a 2006 nissan titan. the contact stated after having nhtsa campaign i.d. numbers remedied on the vehicle 10v074000 (fuel system) and 10v517000 (engine). after the vehicle were repaired the power train was defective. the contact was unable to drive the vehicle off of the dealers parking lot. the vehicle would not move forward or in reverse. the dealer performed a diagnostic test that displayed a defect to the front brake solenoid. the contact called the manufacturer regarding the power train defect. the manufacturer stated the recall repair and the brake solenoid was unrelated. the contact did not have the solenoid repaired. the failure mileage was 122,000.

I own a 2006 nissan titan with 47000 miles. partial vin "1n6ba07a0" while taking it to the local midas shop for an oil change. the mechanic pointed out a leak on left rear axle seal. they quoted me with $350.00 to replace the seal. however they also suggested to have the dealership attempt to replace under a recall/ warranty... the dealership quoted $1900.00 to replace the whole rear axle under the guidance from their technicians and it being over the manufactures warranty and/or no recall. this sounds like a ripoff. here is a quote i found on the club titan forum site. http://www.clubtitan.org/forums/archive/index.php/t-32631.html "left rear axle seal blew out and leaked differential fluid. differential fluid leaking on rear brake rotors which could cause brake failure, which was a major safety concern to me. at time of failure at 8000 miles no suspension modifications had been done to vehicle. also, the rear differential oil will slowly leak and cause the rear differential to lose fluid and fail. nissan replaced spacer axle (43070-7s200), bearing (40210-7s210), and seal (43252-7s200). as this seemed to be a very common problem with the nissan titan, nissan should address this issue and offer a permanent fix so weould not be faced with the safety issue in the future. *ak"

Today i found that my rear axle oil seals are leaking. it is so bad that the oil is getting on the rear brakes. which makes sense considering i have noticed that my rear brakes are not functioning properly. this problem needs to be addressed with better oil seals so that this does not happen to anyone else. *tr

Left rear axle seal blew out and leaked differenital fluid. differential fluid leaking on rear brake rotor which could cause brake failure. this is a major safety concern to me. the leaking differential fluid will caused the rear differential to fail. this seems to be a very common problem with the nissan titan, nissan should address this issue and offer a permanent fix so titan owners would not have to deal with this safety issue in the future. *tr

First of all ,i would like to say that my truck has high miles.i purchased it new, dealer serviced only.in fact my truck was serviced by a dealer in miami on 3-28-13 for oil change ,the day before i lost my transmission because of ,what i now know to be common place, a $5 cooling tubing that goes to the transmission. my first thought was maybe the tech at the dealer broke the tubing since its inches away from the oil filter and my vehicle was serviced there hours before i lost all my fluid,therefore burning up my transmission, you would think that the dealers would check the tubing since its right in the tech's face while conducting oil changes. oh well ,my truck was well maintained,still looks great,totally loaded le, my tranny went down without warning,this will cost me around $6000.i`m a nissan man,i just purchased the new 2013 pathfinder for my wife back in december before it even appeared on the streets, should i have fears about defects with this one ? what's going on nissan ?

Rear axle seal failure destroyed parking brake shoe parking brake will not engage. *tr

Front pinion seal leaking possibly get on exhaust and cause a fire and destroy electrical wiring. *tr

While driving the truck in 2wd i heard a very loud clunking (metal on metal) noise coming form the front of the truck. after reaching home, i realized that the front axle was falling out of the front differential. i jacked the truck up and dropped the front diff pan. this is where i realized that the clips hold in the front axle have failed and broke in two. this is a huge safety concern, had i been traveling down the highway i could have been killed if the wheel came off. i researched online and discovered this a common problem. *tr

Sitting overnight with temperature in the 40's, when putting the automatic transmission into drive,it would keep dropping out of gear. the truck drove fine when manually shifting through the gears. problem continued for most of a year but did not generate an error code. finally developed an error code indicating problem in first gear of the transmission valve body with tcm. this required replacement of valve body internal to the transmission, which had been contaminated by an undetectable radiator to trans cooler leak also requiring the radiator to be replaced. i have been told this is not an uncommon problem, for which nissan has done nothing, other than putting a special coating on bolts internal to the transmission to detect the presence of coolant. this problem can cause complete failure of the transmission. it could be easily prevent by the installation of a separate transmission cooler. *tr

Heard noise in transfer case, took in to mechanic to have problem checked. found out anti-freeze and trasmission fluid were mixed together. transmission had to be rebuilt. after repair needed additional repair to repair transmission line that had came off.

Rear axle is leaking on the passenger side. *tr

My 2006 titan started vibrating like running over rumble strips on side of highway. took straight to dealership. was told that the cooling system split and contaminated the transmission. i had to have the transmission and radiator replaced $7313.56. there was no warning or anything. after reading many complaints for the same thing on other nissan vehicles, there needs to be an investigation and a recall on the cooling system that can cause this amount of damage. *tr

Had truck in shop for exhaust pipe falling off and it was brought to my attention that both the left and right rear axel seals and bearings are bad and need to be replaced. the axel had been leaking fluid onto my tires and brakes which could have resulted in brake failure or fire. nissan will not warranty the rear axel repairs. this is the second new nissan factory axel to be installed on this vehicle since purchased new in 2006. it is currently having the rear seals and bearings replaced at my expense. this seems to be a common problem with the nissan titan model and should be recalled. *tr

Noticed the drivers side rear axle seal is leaking fluid. could potentially cause the axle to seize and/or brakes to fail. this is a major safety issue and should be recalled. luckily i had a mechanic notice it before i got into an accident. this is a dangerous and expensive problem that should be covered by the manufacturer due to poor quality parts. *tr

Both rear axle seals are leaking and need replaced. i have never pulled anything with this truck and at 70,000 or even sooner, i'm not sure when it started leaking, you should not have to pay for replace rear axle seals. *tr

2006 nissan titan rear axle seals began leaking. vehicle has never been off the pavement and has had all maintenance performed by the owner manual list. *tr

Right rear wheel seal is leaking badly noticed at 65000 miles but it looks like its been leaking for a while. this problem seems to be frequent and it also seems to be a safety issue it oil leaking onto the brakes. *tr

I was having my vehicles front differential fluid changed and the service technician noticed 2 cracks around the axle housing. upon further inspection the housing was damaged enough to wear it could leak and cause failure. *tr

Rear axle seals leaking gear oil. replaced by certified mechanic twice and the leak persists. *tr

Both rear axle seals started leaking all over my brakes and inside the wheel well causing poor breaking ability. i called the nissan dealer and they told me this is a common problem with titans and that they no longer recommend replacing just the seals but instead the whole axle. the tech (who told me he had 20 yrs with nissan) said that when they used to just replace the seals people would have to come back 6 months later because the seals would blow again. all of the posts online say that it is a result of an improper venting system that does not allow for the release of negative pressure. if this is such a common problem, and nissan knows that it is, why don't they do a full recall? this is a very dangerous problem that can cause brake failure. *tr

I noticed an exhaust leak on my truck. took it to a reputable exhaust shop, they told me their was a crack in the converter and i needed to take it to the dealership. after checking the web i realized it was under warranty (80000 on exhaust emissions) my truck only had 65k. they replaced both manifolds as they were both cracked. this repair would have cost me 2500.00! after seeing this was a common problem with the titan trucks, i think this should be addressed. also the dealership told me i had a front differential leak which was the pinion seal, this repair will cost me 300-500.00. of course its not covered under warranty so i will have to pay this. after seeing this is also a common problem, i feel nissan needs to correct this issue as it is a safety problem for both me and fellow motorist. my truck has 65,000 miles and is babied! total repairs would be around 3000.00 for the manifolds and the differential, i feel something needs to be done as this is an ongoing issue. *tr

My 2006 nissan titan has an axel seal failure on the drivers side rear, differential fluid is leaking onto the rear brakes causing reduced braking and also the potential for axle/differential failure. nissan refuses to address this design flaw. they have a re-engineered replacement axle shaft and seal at a cost of about $800 per side. this should be a recall not $1600 out of my pocket to fix. will nissan and ntsb wait until there are fatalities before they address this common issue with the nissan titans? *tr

Just replaced the rear seals for a nissan titan 2006. problem began at 65,000 miles. i was told that lack of fluid due to leaking could cause the vehicle to lock-up while driving. the internet is filled with complaints regarding this issue. this seems to be a major safety problem. also had tailpipe issues (dropping from the truck) which is also well documented on the internet and, again, a safety problem. needs to be recalled. *tr

Rear axle seal, driver side, and soon after, the passenger side as well, failed. differential fluid leaked out onto inner wheel surface, brake parts, and immediate area creating hazardous conditions. this is a widely known problem for nissan titan owners and nissan is, and has been, well aware of this problem and has not offered a design solution to my knowledge. nearly every titan experiences this seal failure at some point. some while still under warranty, (which typically get repaired by nissan) but as for the rest of us who are beyond our warranties, we are left with this hazardous condition and a big repair bill. **this should be a recall, or at least repaired by nissan at their expense. its my understanding that there was a technical service bulletin outlining the issuefor nissan mechanics. please help** *tr

I just went into the dealership last thursday the 27th of september to have a routine oil change performed. as part of the inspection the technician noticed that my rear axle seals on my truck were seeping/leaking again. the dealer had replaced the rear axles and seals under powertrain warranty at 46520 miles on the odometer. the truck now has a little over 54k miles and they are going out again. so essentially 14 months after the dealer replaced everything it is out again. i am going to contact nissan directly again to get this repaired even though i am out of warranty by less than a month. this is a serious safety concern for both my family and other drivers on the road as these seals can leak oil onto the brakes and could cause a rear end failure at driving speed which could endanger lives. this truck has low miles for a 2006 and tows a light trailer with atvs a few times a year. all manufacture maintenance is performed on time by a certified mechanic. *tr

Axle seals on rear of vehicle leak excessively. *tr

Rear axle seals have now failed for the 3rd time. nissan dealers tells me nissan will not permit them to replace seals alone. nissan corporate headquarters fix is to replace entire axle assembly at a cost of approximately $800 each axle. nissan is obviously aware of a design problem, but will not take the lead to fix, but put the cost of a defective design on the back of their customers. nissan service representative told me there is a flaw in the materials used in the differential and differential is not venting properly thus causing the seals to prematurely fail. i fail to understand why a recall has not been issued since this is a common problem on nissan titan trucks that nissan will not face. sounds like nissan is having a toyota moment and burying their head in the sand. *kb
