Problems with 2007 Nissan Pathfinder POWER TRAIN

Vehicle started vibrating at 40mph took it to a mechanic they advised that the radiator needed to be replaced and that the radiator and transmission fluids mixed, replaced the radiator flushed the transmission vehicle was at 90,000 miles drove the car another year with slight vibration still at 40mph now it is at 106,000 miles transmission is slipping when it warms up won't come out of 2nd gear looking at having to rebuild the transmission for 4500.00, the radiator was 400.00 plus an outside cooler for the transmission an additional 200.00. had i been made aware of a potential problem i may have been covered because under 80,000 miles i had an issue with the vehicle not heating up when idol the heat would only work when i drove the car and the service engine light was on but the diagnoses was a fuel cap 3 gas caps later the engine light is still on and i had a heating element replaced but it seems that the heating issue is a sign of the transmission issue. nissan should have made it's customers aware of the issue i purchased the vehicle in 2010 with 13.000 miles on it they were well aware of the problems. i contacted nissan and there response was what would you like us to do i don't think the class action suit was fair to the consumer i don't qualify due to the cut off date and now the mileage but i would rather give a transmission shop 3500.00 rather than give nissan 3500.00 i feel that i already paid them enough and for them to know of this issue and not notify the consumer is terrible i have 3 children i drive on the highway in fact i had my 2 year old in the vehicle when the transmission wouldn't come out of 2nd gear it slowed from 60mph to 30mph luckily i was able to pull into the breakdown lane and switch into neutral and back into drive to get it to shift so i could make it to the nearest exit.

Coolant has leaked into my transmission. my vehicle currently has 88000 miles and my transmission has started slipping. i took it to my mechanic who checked the transmission fluid and he said "yeah, it's a mixer". referring to the coolant that leaked into the transmission. according to him im not the only person who has brought in their nissan with this issue.i went to nissan but they said there is no recall. after checking online it seems there was a class action suit brought against nissan back in 2012 but it seems like i can't be part of it since the deadline has passed. i hope there is a recall soon so i can get my truck fixed.

Started hearing a loud knocking when putting my car in park or other gears. took it in for my regular scheduled service and told the service writer at nissan what was going on. he checked it and said he would not let me drive it and offered a rental , told me he would call. well surprise $7600 price tag, said nothing about the recall, i found that myself. but he told me nissan would pay part and my co-pay is $3000. he told me the inter cooler in the radiator had cracked and leaked, sending fluids into my transmission and killing it. on top of that they want to replace with a re-manufactured transmission. according to the extended warranty guidelines of the class action suit, my vehicle just turned 9 yrs. approx. 3 weeks ago and only has 79,000 miles. you would think since it's only 3 weeks out of 8 yrs. and within the 80, 000 they would replace for free. i was never even notified of the recall, i have my car serviced at the dealership i purchased from, i don't understand why they didn't tell me or take action before this happened. i have contacted nissan north america, who knows maybe they will do proper business and fix their manufacturing defect.

The radiator is mixing anti-freeze and transmission fluid together and cycling it threw the whole engine

In april 2016 while driving on the highway the vehicle began to lose power. suv managed to make another 10 miles or so until the slipping was to bad to continue driving. stopped the car and allowerd it to cool. opened the radiator cap and discovered that the trasmission flud and radiator fluid had mixed. the suv is now at a repair shop and will not be covered due to be over the extended warranty mileage. i also own a 2008 nissan frontier that is also succeptible to the same problem.

Tl* the contact owns a 2007 nissan pathfinder. while driving approximately 30 mph, the contact heard a popping noise coming from the transmission and the check engine light illuminated. the vehicle was taken to an independent mechanic who diagnosed that the transmission sensor failed. the vehicle was taken to another independent mechanic who diagnosed that the radiator coolant was leaking into the transmission. the manufacturer was notified of the failure and stated that the warranty had expired. the vehicle was not repaired. the failure mileage was 129,000. the vin was unknown.

On march 14th 2016. we purchased a nissan pathfinder 2007, on the day it was purchased? it shut down in the grocery store parking lot! we had it towed back to the dealer, got it back? and then the car shut down again in the middle of the street! in a high traffic area! my husband cant walk far because of his disability and we had to sit in the car and wait till the tow truck came! march 7,2017 the day after our first payment! the dealership then told us it was a leak in the radiator coolant hose due to some flaw in design! they told us it would cost 1500 minimum to fix! we owned the car less than a month! made one payment! and now we can't drive it or afford to fix it! because our vehicle has 100,000 miles nissan, instead of just fixing their engine flaw?wants to charge us 3,000 dollars to fix it! we are on a fixed income both my husband and i are disabled,and financed into a truck that could have killed us! this needs to be a straight and fair recall with no cost to the consumer! this car could have shut down anywhere! leaving us stranded! or worse!

Radiator cracked and leaked fluid in to the transmission.

My car start to slip up so i done some research and found out that my transmission have coolant mix in it also open radiator cap and found milky looking coolant. my car have only 114000 miles.3/2016

Takata recall out of the clear blue i was driving my 2007 pathfinder and the airbag light came on, i took it to the dealership immediately that day and it passed per service manager louis castillo at baker jackson nissan in houston texas, 2 days later the light came back on and once again i went to the dealer ship and was told that the sensors and other parts needed to be replaced the cost is $1500. i called nissan corp and they are refusing to taking responsibility even though they stated all 2007 pathfinders in other states would be given a 10 year warranty. my truck was also affected with the radiator flulid mixing with the transmission fluid, during the years of 2010-2012 i constantly took my truck to baker jackson nissan and the service manager then larry just topped off my truck himself and never made a record of it. he kept assuring me that he was saving me money. my transmission failed but because of the mileage in 2012 nissan was able to deny fixing my transmission via the class action lawsuit. i ended up spending $4800 for a new transmission. in 2010 nissan convinced me to replace my train for $1600, i never knew it was a recall until today. another caveat to this mess is that baker jackson changed their computer system and has no record of me replacing my train. i have a bank statement to prove it if necessary.

Tl* the contact owns a 2007 nissan pathfinder. the contact stated that the vehicle would not change gears from drive into reverse. the vehicle was not diagnosed nor repaired. the vehicle was unable to be driven and was towed to the contact's residence. the manufacturer was notified of the failure. the failure mileage was not available.

Tl* the contact owns a 2007 nissan pathfinder. the contact stated that the transmission was defective and caused the vehicle to jerk and lose acceleration while driving. the engine light also illuminated while the failure occurred. the vehicle was taken to the dealer where it was diagnosed that the radiator fluid leaked into the transmission, which caused the transmission to fail. the transmission was not replaced. the manufacturer advised that the extended warranty would not cover the entire cost of the transmission replacement. the failure mileage was 95,000.

My suv was diagnosed with a manufacturing defective transmisson and now has issues with the transmission cooler pipes splitting causing cross contamination between the radiator coolant & transmission fluid. which resulted in a failure to the automatic transmission. the cross contamination had to have a new transmission, transmission cooler hoses & radiator replaced.i called nissan corp and they are refusing to take responsibility i told them that they are putting familys in a dangerous situation. i also explained to them when i purchased my vehicle they where well aware of the situation but concealed that information from me and i let them know that i was pregnant at the time with our 4th child and needed the 3rd row thats why we traded, so i did not appreciate that information being concealed from me and putting my children in a unsafe vehicle. nissan has caused me to almost wreck 3 times this has caused so much stress on me and my family.i have reached out to nissan corp several times with they refused to fix it or return it and give me my money back.and also i delivered my baby 10 days later after i purchased the pathfinder and the patherfinder had about 70,000 miles on it already so the transmisson could had easily went out at any time since it had known problems that were concealed from me and caused a very dangerous situation for me and my baby because when i bought the vehicle they concealed the information knowing that it could happen at anytime and refused to let me know even though my husband and i both asked if anything was wrong with the vehicle and they told us no they check the vehicles before they sale them by their mechanics.something needs to be done before someone gets killed. my pathfinder only has 123,000 miles on it.

Tl* the contact owns a 2007 nissan pathfinder. the contact stated that the vehicle was being serviced for an oil change, when it was diagnosed that the radiator fluid was leaking into the transmission. the dealer stated that the radiator and the transmission needed to be replaced. the vehicle was not repaired. the manufacturer was not made aware of the failure. the approximate failure mileage was 124,789. the vin was not available.

After hearing a lot of about this problem i decided to make a complaint because it is not fair for anyone to go through this. my 2007 pathfinder suddenly lost complete power and it wouldn't start at all after having a mechanic check it he gave me a diagnose that it was the transmission which i didn't believe i said what does the transmission has to do with power but it has a lot to do after i did some research it comes to this. the coolant on the vehicle gets inside the transmission and mixes with the oil causing the tcm (transmission control module) to fail and not to sent signal so the vehicle will start. so now i have to repair the transmission and the radiator cost will be more than 3000 dollars. i been the only owner of this car and have take good care of it as much as i can i just pay off this car 2 years ago and i don't think is fair for us that had has this problems to paid for it i think nissan america should do a recall on this and help us the consumers.

Transmission control module fried due to contamination from the radiator fluid. nissan was aware of contamination in transmission through the radiator and this contamination causes the control module in the transmission to short. every time i want to start my vehicle i have to replace a 10amp fuse under the hood that will always blow every time i start it. repair cost for a new control module are exceeding $4000 every place i go. nissan should be responsible for repairs of their faulty design. due to this defect my family was stranded, i had to leave my work and pick them up in below 30 degree temperatures.

Problem started when transmission started to slip while driving back and forth to work.. had transmission flushed did not help...learned about the inter-cooler defecate so checked the radiator to find tranny fluid.. car is over 100k miles so left with all repair cost and a sorry about your luck.....

At first, the car wouldn't start occasionally. i replaced the battery and fuses. this helped temporarily. now, the car won't start unless i place a new ecu fuse each time i attempt to start it. changing the fuse will start the car, but it lacks power and is quick to stall out. when i took it to the mechanic, he discovered coolant in my transmission. after reading information from several websites, i realized this is an ongoing issue with this make/model of car.

1) about 2 years ago the cruse control stopped working. have not repaired this problem. 2) in july 2015 the air bag warning light on the instrument panel started flashing. have not repaired this problem. 3) on dec 21, 2005 after pulling out of my drive way the transmission would not advance to the next higher gear. stopped and put it into reverse but the suv would not go backwards. slowly drove it around the block back home. transmission shop reported that coolant leaked into the pcm compartment causing this problem. repairs have been made, cost was 3645 us dollars.

Tl* the contact owns a 2007 nissan pathfinder. the contact stated that while driving at 15 mph, the check engine warning light illuminated. in addition, the contact attempted to reverse and shifted the gear shifter into reverse but the vehicle failed to move backwards. the vehicle was taken to a dealer who stated that there was automatic transmission contamination due to anti freeze from the radiator. the technician also diagnosed that the transmission needed to be replaced. the vehicle was not repaired. the manufacturer was not notified of the failure. the failure mileage was 76,000.

Coolant leaked into transmission causing damage to transmission. vehicle is in shop with estimate of $5000 for repairs. mechanic stated it is difficult to find rebuilds and that this is one of the most expensive transmissions he has priced. he did some research and found that this is a common problem and makes is more difficult to get rebuilt transmissions. i initially had the coolant leak fixed and replaced the radiator. the transmission would shift rough and in three months time from coolant leak repairs, started to not shift from 2nd to 3rd gear. car in not safe to drive and was taken to mechanic.

Radiator failure allowed coolant to leak into the transmission both the transmission and radiator now need to be replaced. nissan has known about this problem for a long time and has failed to issue a recall. our vehicle dropped into 1st gear while driving and nearly resulted in us getting rear ended.

Fluid has leaked from the radiator into the transmission causing corrosion in the transmission. transmission stalls and shutters while driving it. this causes a safety hazard, due to lack of power and possible loss of transmission during driving. this is a known defect in nissan pathfinders.

In october of 2015, while driving down the interstate, the vehicle lost power. it has happen 3 times since (the most recent being march 22, 2016). an independent repairman has look at the vehicle 3 times, but has not been able to identify the problem. spoke with the nissan dealership where purchased and they were not able to determine the issue over the phone. we did discuss the transmission/engine coolant mixing. taking the vehicle to the dealership for further evaluation. they said it is not covered by warranty or recall. there was a class action lawsuit but our vehicle already had too many miles to be included.

Coolant aft cross contamination in the transmission and radiator.

Tl* the contact owns a 2007 nissan pathfinder. the contact stated that while driving approximately 30 mph, the vehicle violently jerked forward without warning. the vehicle was taken to an independent mechanic where it was diagnosed that the transmission fluid and anti freeze mixed together and the transmission and radiator needed to be replaced. the vehicle was not repaired. the manufacturer was not notified of the failure. the failure mileage was 97,000.

My wife was taking the kids to school and while driving in the drop off line heard a loud "thunk". we had to get it towed to the nearest dealership and pay the $99.00 diagnostic fee to find out that the radiator leaked coolant into the transmission, which caused transmission failure. apparently this is a common problem that nissan is not addressing.

I bought this vehicle new in 2007 as our 2nd new nissan .our first was a 2005 frontier with no problems and now this. i have been experiencing transmission problems. it slips when accellerating and somtimes wont down shift properly. so due to the problem i did a web search and found this cracked transmission line allowing coolant leak in to the transmission, so i checked the resevour and radiator and both had atf contamination. i then called the nissan dealer and they claimed to have no idea what i could be talking about. the class action lawsuit filed in late 2012 stated that all dealers were notified. i was never notified and now have over 100,000 miles on my pathfinder which opts me out of anything. this is rediculous and nissan needs to be held accountable! they never even admited there was a problem just offered some extended warrenty coverage absolutely absurd! now im stuck with a vehicle i cant even drive.

Tl* the contact owns a 2007 nissan pathfinder. while driving approximately 50 mph, the rpms increased rapidly and the engine warning indicator illuminated. in addition, the transmission slipped and failed to shift into the reverse position properly. the failure recurred two times. the vehicle was taken to the dealer where it was awaiting diagnostic testing. the manufacturer was not notified of the failure. the approximate failure mileage was 144,000.

As i was about to enter the highway my vehicle lost power, i was fortunate to be able to get off the on ramp and back to the frontage road before my car came to a complete stop. took to a repair station where it was found the radiator failed and allowed fluid to mix with the transmission fluid. transmission is a complete loss, although the cost of repair ($5200) is troubling, the fact that moments later my family and i could have been injured or caused someone else to be injured is the bigger issue. i have seen numerous complaints about this defect and feel the nhtsa should take a better look into making this a safety issue. at some point someone is going to die from this. nissan has made a very un-reasonable attempt to address this issue.

Transmission failed due to coolant leaking into transmission. had my whole family when transmission gave out don't want to image what would have happened if i was going faster than 35 mph. cost to repair $5800. dangerously unacceptable.

I was driving my 2007 pathfinder with my 3 children in the back when the tires suddenly seemed to be slipping. i wasn't sure what was going on until i was on a big hill and car suddenly wouldn't go into gear. the transmission had blown on me, almost instantaneoulsy with little to no warning signs. the car started rolling backwards on the hill and luckily nobody was behind us. i hit the breaks and stopped the car. it had to be towed and i was stunned when my mechanic said the transmission was dead and it would cost around 3k to fix! "there was only 85k miles on the car and the transmission just blows like that," i asked him? he told me that this was a problem very common with some nissan cars. i immediately went online and found out that this is known problem with nissan pathfinders and xterras, due to fault manufacturing and a lawsuit was brought up against them (a few years before this happened to me). i feel it's outrageous that these cars can still be sold by the dealer (we bought it used with 60k miles on it) without some sort of warning label on it. thank god my kids didn't get hurt somehow, because it was quite a hazardous situation when the transmission fails suddenly at the top of a big, long hill! if my kids had gotten hurt, i probably could have sued them for a billion dollars, but since i acted quickly, nobody was hurt, and thus, nobody at nissan seemed to care when i complained. they should be held accountable for fault manufacturing! no car's transmissions suddenly break down for no apparent reason with less than 90k miles on it!

Found out that my radiator had a failure and a transmission hose cracked inside the radiator and the transmission fluid all mixed up to invaded both the motor cooling system and the transmission.. dont want to go in gear when turning and it make this rumbling nose when you driving it

Tl* the contact owns a 2007 nissan pathfinder. while driving 5 mph, the transmission failed to shift gears and the engine warning light illuminated. the vehicle was taken to an independent mechanic. the technician diagnosed that the transmission control module and the radiator needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the failure mileage was 111,000.

I was just informed by a fellow nissan owner about her transmission replacement. why was i not notified by nissan that there was an issue? no card, letter... nothing! i would have had my car inspected for defect if i knew!!

As i was driving the vehicle on the highway it started to shudder and shake and then finally completely turned off on the highway. once i got it started again it would only go about 20mph i was able to move over to the shoulder and exit the highway. once we took the car to the dealer, they told us that the radiator had leaked into the transmission and also that i needed to replace two catalyctic converters. the total repairs and replacements would cost me $8000 as i would also need to replace the transmission and radiator. we replaced the radiator but of course that is only half the problem. i still owe about $13k on the vehicle, have only had it for 8 months and am now stuck because i dont have the money to replace the transmission and i cant get rid of the truck knowing this problem.

Towed my car to the local shop and found out that the radiator has an internal crack and leaked into the transmission. burned out the tcm and now i am going to have to pay more than $5000 to get it fixed. called nissan and was told i needed to replace the radiator and transmission. not happy about this at all.

2007 nissian pathfinder -radiator leaked into transmission, causing failure to transmission. replaced radiator, all fluids and flushed out secondary radiator and reservour and new thermostat, flushed out transmission fluids. now needs new transmission, which is the most expensive part of the job!

We purchased our 2007 nissan pathfinder on may 21 of this year. today makes 39 days we've had it. on the 32 day we noticed it was having some roughness in the transmission when changing gears. it felt like we were running over really rough roads or rumble strips. it continued to get worse the longer we drove it. then around a week ago i put it in reverse and it continued to roll forward. i immediately drove home to inform my husband. when he checked the transmission fluid it appeared to be empty. when he further checked it and cleaned the dip stick it was a tanish colored liquid that was showing up. i went to google and found that many others with this same or similar vehicle was having the same problem, and that the problem was a leak in a radiator hose that runs thru the transmission and leaks fluids back and forth. my husband went to check the radiator and sure enough there is transmission fluid in the radiator and it appeared in the engine as well. so now we have transmission fluid, water, and antifreeze in our transmission, radiator and engine. nissan needs to step up and take care of this problem. its clear that this is a flaw in their workmanship. we were told by nissan to bring our pathfinder in for an evaluation and be prepared to pay 2,500.00 dollars. needless to say we are paying a payment already on a vehicle we have had for one month. we cant afford this kind of repair. so now were stuck with a car we cant even drive.....updated 09/03/15 *bf

Onset of issue was inspection to determine service engine light. code p0850 - indicated park/neutral safety switch input circuit. switch replaced and service engine light back on within 48 hours. returned additional codes related to transmission. concurrently the vehicle was stumbling at certain speed/rpm with rumbling noise in drivetrain and hesitation during accelleration. transmission found to have been contaminated by radiator fluid. complete rebuild of transmission performed and bypassed radiator transmission cooler with auxiliary cooler to prevent having to replace radiator. transmission rebuild and rental car for a week >$5000. the consumer requested ti be reimbursed for the cost of repairs. *js

Tl* the contact owns a 2007 nissan pathfinder. the contact stated that when shifting, the vehicle would jerk violently and the check engine light illuminated. within minutes, the vehicle stalled and could not be restarted. the vehicle was towed to an independent mechanic who stated that antifreeze fluid seeped into the transmission. the mechanic stated that the transmission and radiator needed to be replaced. the manufacturer was not made aware of the failure. the vehicle was not repaired. the failure mileage was 133,000.

Possible transmission failure. brought vehicle to be inspected and could get a clear answer which one of the observations was perform at a nissan dealer. the fluids seems to be mixed, transmission with radiator fluid. seems as this has been and on going problem with nissan. dealer tells me the cant find the recall.

Tl* the contact owns a 2007 nissan pathfinder. while driving at 10 mph, there was an abnormal noise that came from the transmission as if the vehicle were in neutral. the vehicle was not diagnosed or repaired. the manufacturer was not notified of the failure. the approximate failure mileage was 80,500.

My 2007 nisson pathfinder began having problems and when i brought it to the mechanic, he stated the coolant fluid went into the tranmission and caused major problems and now the radiator and transmission need replacement to the tune of $4900.00 (approximate price given by lee myles). i actually brought the car to a nissan dealer and their quote was $5800.00 and then they statated other isses needed to be repaired and they stated the total cost would be $10,000.00! book value of the car through kelly blue book is $9,600.00 in excellent condition! i saw this is an ongoing problem with pathfinders and i wanted to tell my story. i hope there is something that can be done against nissan! *tr

The radiator leaks fluids into the transmission, intermixing the fluids. this is ruining the radiator and transmission, causing the vehicle to overheat and leak. this makes the vehicle not safe to drive. *tr

Radiator failed, mixed coolant into transmission fluid caused transmission to fail.repairs estimated at $5000. *tr

I was driving back home from my daughters doctors appointment. it was during rush hour traffic time. as i was trying to accelerate i felt a jerk on the card and the o/d light start flashing. i was almost home so i kept driving to make it home. did not want to b stranded in the road with my daughter. as i pushed on the gas it did not want to accelerate an more, all the lights started flashing and we pretty much strolled into the nearest gas station. i put it in park and waited a moment and tried to see if it would cut back on, but it didn't. i had my vehicle towed to the mechanic shop and he said it smelled like radiator fluid. after doing diagnostic he said problem was to due to a crack that leaked radiator fluid into transmission. so now i have to replace my transmission and radiator and computer. cost would be over $5,000. *tr

Tl* the contact owns a 2007 nissan pathfinder. while driving at approximately 50 mph, the vehicle started shaking and an abnormal noise was heard under the hood of the vehicle. the contact stated that the accelerator pedal was depressed but the vehicle failed to accelerate without warning. the failure recurred numerous times. the vehicle was taken to a dealer. the technician diagnosed that coolant leaked from the radiator into the transmission and the radiator and transmission needed to be replaced. the vehicle was not repaired. the manufacturer was made aware of the failure. the failure mileage was approximately 93,500.

Radiator leaked anti-freeze into the transmission which destroyed the transmission and the entire coolant system. nissan has known about this but never issued a recall.

Tl* the contact owns a 2007 nissan pathfinder. the contact stated while driving approximately 60 mph, the transmission exhibited severe vibration. the vehicle was taken to an independent mechanic, who replaced the radiator and flushed the transmission twice. the failure continued after the repair was performed. the mechanic recommended that the transmission be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 65,000.
