Recently reported POWER TRAIN problems on 2006 Nissan Pathfinder

El vehiculo coje la reversa pero no el drive y no quiere arracar no la puedo usar ni mover hacia frente

I was driving on an interstate at normal highway speed when the car shuddered as if going over rough pavement. the engine started racing, but the car gradually lost forward propulsion. i steered to the emergency lane and stopped. after a minute, the car regained just enough forward motion to get me to the next exit, across an intersection (where the light just happened to be green, thank goodness), and into the parking lot of a large grocery store before the vehicle lost all propulsion. we pushed the car the last few feet into a parking spot. it was towed to a nissan dealership. i was told the next day that the transmission warmer had failed, allowing radiator coolant to leak into the transmission, which ruined the transmission. the repair would cost $6000. i cannot put another $6000 into a 13-year-old vehicle, even though i've only had it for five months, so now i've lost the money i put into it and will have to start over with another vehicle.

Transmission is failing quickly. i had to replace my radiator a few months ago because it cracked. that event left my wife and children stranded on the interstate.

Radiator failed causing leak of radiator fluid into transmission causing vehicle to be towed to auto shop. vehicle was in motion on highway and then would all of the sudden no longer accelerate. mechanics, (got 3 estimates) all said same thing; that this was a problem with these pathfinders. my cost is about 6,500. i had just bought this vehicle for 8,500 about 3 weeks prior.

There is a system design flaw with the 05-10 nissan trucks; pathfinder, frontier, xterra. the radiator houses both coolant and transmission fluid. when the radiator fails, it leads to coolant and transmission fluid mixing; resulting in catastrophic failure and premature destruction of the transmission. our transmission was replaced with a brand new transmission after the original transmission failed at 89k miles. after the new transmission was put in, the transmission was destroyed at 90k miles and the issue was traced back to a cracked/ruptured radiator; leading to mixing of coolant and radiator fluid which in turn ruined the transmission. the cost of the initial transmission replacement was $6000; the estimated cost of replacing the transmission again along with the radiator and flushing the system and replacing the fluids is $8000. in both instances of transmission failure, it happened during driving conditions on a highway without symptoms of transmission issues. the worst part of this is not the cost. the worst part is that this known issue on nissan trucks should have been classified as a recall issue because the failure can happen anytime, especially during driving conditions and has the potential to cause a crash, serious injury, or death.

My vehicle suddenly started to have a delay in acceleration when the gas pedal was pushed, and then would catch and lurch forward. i have been told that the transmission inner cooler ruptured and has ruined both the radiator and transmission. further research indicates this is a known issue that nissan has failed to accurately advise owners about, or issue a recall. this is negligent and wholly unethical. negligent in that the symptoms could lead to serious harm out injury, as there is no warning prior to the damage being done. unethical in that now nissan gets to profit from their negligence, as it will cost $5,000 to remedy what could and should have been much less costly.

Tl* the contact owns a 2006 nissan pathfinder. the contact stated that the "overheated" warning indicator illuminated while driving approximately 25 mph. the following day, the vehicle failed start. the vehicle was towed to an independent mechanic who determined that the radiator failed and caused coolant and transmission fluid to mix. in addition, the transmission control module failed. the mechanic stated that the engine had to be rebuilt and a new radiator needed to be installed. the dealer and manufacturer were not notified of the failure. the vehicle was not repaired. the approximate failure mileage was 87,270.

Car overheated/no start, had suv tolled to auto repair shop was told by techician was told the following. radiator failed causing coolant and trans fluid to mix. transmission control module failed causing vehicle not to start.

My problem is with the radiator and transmission fluid contamination.. some hoses inside the radiator that carries transmission fluid and coolant cracked and contaminated both the radiator and transmission. this problem has caused my vehicle to lock into 4 wheel drive and contaminated both my radiator and transmission this problem will need to be repaired before the vehicle can be driven. it will be a costly repair that should be covered by nissan on a recall according to all the complaints i have read about.

Transmission has went out due to factory default there's a recall on the exact issue that i'm having with my car i need to know if there's an extended warranty or something to remedy this because it seems to be a known issue

Radiator malfunction cracked transmission lines, mixing antifreeze into the transmission lines, contaminated the transmission, the transmission is ruined! never informed about this defect in the radiator! never no recall!

Catastrophic transmission and radiator failure due to co-mingling atf and coolant at 136,000 miles. contacted nissan north america, they refused to help in any way, but acknowledged this as a "known" issue.

The radiator has broken and leaked into the transmission causing a complete failure in the system. both must now be replaced.

All 4 of my catalytic converters have had to be replaced (or need to be replaced - i've already replaced bank 1. now bank 2 is bad) in the past 12 months or so and now my radiator is leaking into my transmission. i discovered there was a class-action lawsuit on the radiator/transmission issue, but i'm outside of the warranty period. with respect to the catalytic converters, i occasionally smell exhaust, but the check engine lights stay on. with the transmission, it started out as gear slipping, causing rough driving (which the dealership told me was the catalytic converter). then, it started running slow out of first gear and hard shifting. i took it to a transmission place that pulled transmission codes and when they dropped the pan, the fluid looked like a milkshake. the rough driving/gears slipping didn't matter - it could be on the highway or in the city. i don't know the exact date in 2018 that i had the issue, but i've been dealing with this issue for a year.

The transmission would not shift into overdrive, so i took the vehicle to aamco. the transmission was contaminated with coolant from the radiator, requiring a complete overhaul including the transmission computer. estimated cost of damages is $4600! my vehicle is in excess of the extended warranty, however this is a design flaw that should be corrected by nissan.

The radiator was cracked where the transmission fluid is and it mixed with the antifreeze which caused both the radiator and the transmission to have to be replaced. the engine was on and vehicle was stationary when we noticed the temperature increased greatly and rapidly until it maxed out. the vehicle was leaking a mix of antifreeze and transmission fluid. we replaced the radiator but the damage was done already to the transmission. the vehicle was in motion when the transmission failed.

When i was driven my nissan i make a stop and then i try to accelerate but my car didn't respond so i took the nissan to the mechanic and he talk me the transmission was bad do i need a new transmission .i was very lucky because i was very close from home in city street other wise i would has to tow the car to the garage and put my family in danger

I was driving my newly purchased used 2006 pathfinder and noticed that i could not get up to speed until i got up to 45 or 50 mph noticed i had several error codes ended up that one was the transmission valve assy. took it to transmission shop which tested the fluid and found that there was radiator coolant mixed with the transmission fluid. the car was great except for this issue. now it barely drives only in 4th gear and i am told if i keep driving it that way it will burn it up. i need to replace both the valve assy and the transmission and radiator to solve the problem at a cost of 5k. i do not have the money. this is really unacceptable.

Radiator coolant leaked into the transmission $4000 car 10 years old however i had high mileage due to many road trips

Tl* the contact owns a 2006 nissan pathfinder. when the vehicle was taken to the alhambra nissan dealer in alhambra, ca for a routine oil change, the contact was also advised to have a transmission oil change. the technician performed an oil change on the transmission and the transmission failed eight days later. the vehicle was towed to the alhambra nissan dealer where it was diagnosed that the transmission and the radiator failed and needed to be replaced. the vehicle was not serviced due to the repair fees. the manufacturer was made aware of the failure and informed the contact that the vehicle was old in age and out of warranty. the manufacturer did not offer further assistance. the vin was unknown. the approximate failure mileage was 123,000.

A known problem with radiator braking with coolant in transmission resulting in new transmission and radiator 4439.65. nissan should be barred from selling cars in usa with such substandard products/

While driving on the highway, penultimate week. i observed loud engine noise, vigorous shaking and jerking and a reluctance in acceleration when i applied gas pedal​. i was a little bewildered as i have been very punctilious with the regular maintenance of my car. i gently pulled into a parking lot to avert any danger on the freeway. upon exiting the car, i perceived a pungent burning smell. at this point, i knew it would be unsafe and pernicious to drive the car home. i immediately called for roadside assistance through my insurance company and had the car taken to my mechanic. he called back the following day with the most disheartening news. for some uncanny reason, fluid from the radiator was leaking into and contaminating the transmission. he vehemently pointed out that he had seen quite a few of the same ominous problems brought to his shop, involving mostly 2006 nissan pathfinders. i was given a quote of about $4500-$7000 to fix this problem. i purchased the vehicle from a used car dealer with approximately 117,000 miles. i'm currently financing the car and because of my student loan and exorbitant fees, i still owe a lot on it. honestly, i cannot​ afford the repairs at this juncture. it is very rapacious and immoral of nissan to abdicate their responsibility and pass on the financial burden to innocent consumers​. these cars had factory defects and design flaws that nissan was aware of but chose to ignore. i enjoin anyone having similar problems and indeed conscientious members of the public to vociferously condemn nissan's action and force a recall. this is corporate greed at it's worst !!

Radiator transmission cooler failure, causing transmission to fail

Transmission failure due to faulty radiator. vehicle is not drivable. happened while in motion.

Radiator and transmission fluids mixed causing massive radiator blow out and replacement. . cost of $2000 then after being told the transmission survide and limited driving now a few thousand miles later and about a year later now the transmission is shot no reverse and only one forward gear!

Total transmission failure on i95 in connecticut ,10pm at night, at 55mph , with family in car. coolant leaked into the transmission causing a total transmission failure. nissan knows about this problem and did not contact vehicle owners to warn of the problem or offer suggested repair. replacing the radiator would have been a $300.00 fix. instead nissan offered no warning and the extremely dangerous transmission failure on an interstate at night happened. total cost to repair was $4381, plus a week car rental.

This sub has a problem when speed after 35 mph. the engine has to go high revolution 4500 or 5000 rpm wich is not normal. to keep at 50mph .the tramision doesn't gear properly. i took to nissan dealer they said is the tramision has water fron the radiator. the coolant majestic the tramision fail. it cost over 5000.00 for rapair .it need new radiator.

The transmission and radiator fluids are intermingling and has caused my transmission to fail. it has ruined the transmission. it is my understanding that this has happened to thousands of the same make and model.

The transmission and radiator fluid mixing and causing transmission to fail. i see that you have had many complaints about this issue and you choose not to help the consumers. this is a very dangerous issue and a very expensive repair. this is obviously a continuing problem and an extended warranty isn't fair to the consumer because this is a faulty issue with this model transmission/radiator.

Tl* the contact owns a 2006 nissan pathfinder. on several occasions, while driving between 10-50 mph, the transmission failed to operate as intended. the dealer diagnosed that the transmission failed due to contamination of the transmission from the radiator fluid acid. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 170,000.

I paid off my pathfinder last year. just about 2 months ago after leaving a friends house the truck started turning on all the dash board lights, i didn't know what to expect. i drove it very slowly home not even a mile away, i turned it off and next day..my surprise it didn't turn on to take to the mechanic. i called the tow truck to take it in to nissan dealer and they found that the radiator fluid mixed with transmission oil and messed up the module too. they where originally charging me 7200 dollars to fix. i brought it back home and after when i was able to pay with credit i took it in to fix. they urged me to fix all at once because of a manufacturer defect on any of the above..most likely they said it could happen again. *tr

I'm a owner of a 2006 nissan pathfinder. this vehicle has major transmission issues. vehicle shutters and jerks while driving 20 to 30 mph!!

Defective transmission coolant system caused transmission to "slip" making it dangerous to drive.

I have a 2006 nissan pathfinder with 91,450 miles. i notice a slight slip in the transmission on the way to work. i work at a auto repair shop. they took it for a test drive and found nothing. approximately two weeks later, it really started to slip to the point i had to pull over, because it was not shifting correctly. when it was brought in to the shop again it did nothing. i called the local nissan dealer in stroudsburg pa and was told there was a "silent recall" and to check the fluid if it was a milky color, pretty much i was going to be without a car. i always took care of my car and for this to happen was a real blow. the dealership told me pretty much the repair exceeds the value of the vehicle. i did check the value of my car was approximately $6-7000 for the shape that it was in. that's a lot of money to lose on a vehicle. also, the hazard of not shifting properly could have caused an accident, i had to pull off the side of the highway until i could get it to shift and this kept repeating it self over and over. nissan had a class action settlement, which when i called nissan directly they said it did not include my vin number. i believe nissan knew this was a defect and only if you complained about it did you get attention from the company. i had an address change so i do not know if i received any information on this type of issue. i was the only owner of this vehicle and believed that nissan should make good for the repairs it will cost.

I was pulling into a parking space slowly with my foot on the brake, rolling into the space. as i braked a little bit more in order to come to a stop (i never took my foot off the brake), the car suddenly revved up,accelerated, and crashed right through a fence. i was able to slam it into park to get it to stop.

Radiator cracked leaking coolant into the transmission that is impacting the ability for transmission control module to function properly. now, while driving, the car randomly stalls and loses all power. while on the highway, it has become necessary to restart the car while rolling in neutral to avoid having to switch lanes into faster moving cars. i've been informed by nissan that it's a common problem and an $8000 repair to replace the radiator, transmission, transmission control module, and flush everything out.

Had to have steering column replaced due to it breaking and causing hard steering and no control of wheels. barely made it home. also the transmission had to be flushed and by passed due to cooler getting water in transmission. both of these are safety items and nissan dealer says not enough complaints about these problems. cost me $3400 in repairs which had to be done due to safety reasons. the car was in motion each time on freeway and had to stop and get it towed to mechanic because it was unsafe to drive anywhere.

Tl* the contact owns a 2006 nissan pathfinder. the contact stated that when he took his vehicle to the mechanic for maintenance, the mechanic stated that the vehicle coolant was abnormal. as a result, it was diagnosed that the transmission fluid and coolant had mixed. the radiator and transmission needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 115,000. the vin was not available.

Tl* the contact owns a 2006 nissan pathfinder. while driving approximately 60 mph, the vehicle lost power without warning. the vehicle was coasted to the side of the road and towed to a local dealer who diagnosed a transmission failure due to a radiator leak. the dealer completely rebuilt the transmission. the failure recurred. the vehicle was towed to another dealer where it was diagnosed that the rebuilt transmission caused an "inter cooler failure". the manufacturer was made aware of the failure and stated that it was not the manufacturer's problem. the contact was referred back to the dealer that installed the rebuilt transmission. the dealer stated that the manufacturer was aware of the rebuilt transmission and referred the contact back to the manufacturer. the manufacturer stated that nothing could be done. the contact received notification of nhtsa campaign number: 10v517000 (engine and engine cooling). the failure mileage was 168,000.

Raditor leaks coolant in transmittion now my transmittion is not working and the coolant has transmitton fluids in it

My vehicle had problems in 2011 when a "warranty notice" was sent regarding a radiator problem. i took the car in and they found that it was a timing belt and did not change my radiator while it was under the extended warranty and had approximatey 70,000 miles. i now have 160,000 miles and my car is acting up again and the dealership advised me the radiator is cracked and leaking coolant into the transmission so i need both repaired or my car will get worse and can cause an accident. to me it appears that this defect with the car was from the inception and it should have been recalled because it was bound to fail and it should be fixed at nissan's cost. my vehicle is still pretty good looking but i feel it is only a shell that i am driving because of the interior radiator flaw. they indicate that since no recalls were made i have to pay the total out of pocket. i missed the lawsuit in 2013 but am willing to file another class action lawsuit if a lawyer is willing to accept it. the vehicle was shaking when i was driving it on the freeway mainly and it felt like it was not in gear and pulling. these were also my concerns in 2011 when i took it in to be repaired and fixed, but they said i had no problems. well i do now and i wouldn't have if they had fixed the defective radiator.

Tl* the contact owns a 2006 nissan pathfinder. while the gear lever was in reverse, the transmission failed to operate. the vehicle was towed to an independent mechanic where it was diagnosed that the radiator connector hose leaked fluid into the transmission. the contamination caused internal damage to the transmission. the radiator and transmission were replaced. the manufacturer was not notified of the failure. the approximate failure mileage was 85,000. consumer stated while driving up a hill she acceleration and could not make it up the hill and made it to her job. consumer attempted to put the vehicle in reverse and would not go in reverse. car was towed, aamaco diagnosis was coolant had leaked into the transmission causing transmission to fail. updated 6/13/18*jb

Driving home after the car has been warmed up for quite some time it started jerking shuttering violently and whining extremely loud upon acceleration it continued to worsen we checked radiator and transmission fluids there was atf fluid in the radiator and in the reservoir of radiator fluid it was thick frothy and almost a tannish color that like of strawberry milk. we were only about a half a block from home when this occurred and it frightened our children in the backseat thankful we were not on the interstate the shuttering was extremely bad

On highway driving home from work when transmission suddenly failed, causing a dangerous situation for myself and fellow drivers. it was a very harrowing experience, to say the least. it now sits with the mechanic, who informs me that the dreaded engine coolant/transmission contamination issue has occurred...unfortunately, my vehicle is over 10 years old and over 145,000 miles, so the recall notice does not apply...i now have to come up with $5,000 for repairs...how can nissan ignore this issue and neglect their customers?

On the second day of owning my pathfinder i noticed a vibration when i was driving around 40 mph. i took it into the shop less than a week later to have the transmission flushed and to disconnect the radiator from the transmission (did this due to research we found on the internet). the mechanic did see that my transmission fluid was cloudy meaning the coolant was leaking into the transmission. my vehicle was working great for about two weeks until one day i noticed a jerky feeling when driving my vehicle on a city street. that jerky feeling shortly turned into the vehicle shaking when shifting, which turned into not shifting at all after stopping at a red light. my vehicle would barely accelerate, mostly engine revving, luckily i was on a hill where i could coast to the side of the road. this occurred within 5-10 minutes, very quick, little warning. this could have been a very dangerous situation and could have ended worse than it did!!!

Nissan has an issue with the radiator leaking into the transmission,causing the car to shutter while driving.the transmission will go eventually!! nissan is totally aware of the issue,and if you have an extended warranty for the powertrain it is not covered,because they do not consider the radiator,part of the powertrain!!i it will just be a matter of time before it leaves me sitting along the road! i hope i can get off the road and not cause an accident! nissan really need to fix this!! thankfully no incident has happened,but i thought this should be told!

The transmission fluid was contaminated because there was a hole in the radiator. the radiator and transmission need to be replaced. i have 112,781 miles. this is a known problem with nissan pathfinders. nissan extended coverage up to 100,000 miles. the radiator should have been recalled and all owners should have been notified.

Check engine light came on, diagnostic for auto trans sensor. mechanic flushed transmission then couldn't replace sensor due to on going problem with radiator leaking coolant to transmission

Coolant leaked into transmission, destroying the transmission, and rendering vehicle useless without thousands in repairs

We have a 2006 nissan pathfinder that has transmission failure due to a defective radiator. this is a known defect that nissan should be held accountable for. we followed all recommended maintenance, most of which was at a nissan dealership. the dealership was negligent in its inspection and repair of our vehicle. when we began to experience transmission failure and had both transmission and coolant contamination, they failed to diagnose the problem. two nissan dealership inspections in may 2016 outlined that all was well with our vehicle, even after we found that there was no transmission fluid on our dipstick, and it did not appear that the bolt to check the fluid had not been recently removed. our family's safety was put at risk driving this vehicle for over a month, while it was experiencing transmission failure and risked engine failure due to heavily contaminated coolant. after a few weeks of symptoms, we looked online and were shocked to see the widespread manufacturing defect that has been reported. we took our truck to an independent shop who diagnosed the problem. the nissan warranty was extended to 10 years or 160,000 kilometers for possible radiator assembly failure. although our vehicle fell within the 10 year time frame, we were outside the kilometer range by 40,000 kilometers. nissan canada and crown nissan refused to extend the warranty to us. we feel the 160,000 km is far too low for a 10 year warranty. a recent dodge warranty extension was 10 yrs, 240,000 km. nissan put us in an unsafe situation, where they failed to diagnose the problem and we were out driving for several weeks, some of which involved towing our family camper on the highways. nissan has been negligent on many levels and a recall should be extended to these faulty radiators.
