Problems with 2007 Nissan Pathfinder ENGINE AND ENGINE COOLING

Driving car in rush hour traffic and car completing stopped. it took about 10 minutes to start. once the car started it cranked for about 10 seconds before it actually started. at dealership, the car was diagnosed with needing two new cam sensors. after paying $621.00 for this, mechanic test drove car and found it to be "bucking" and diagnosed that the radiator fluid had leaked into the transmission and we needed a whole new transmission. nissan is requiring $2,500 deductible even after they realize they made a faulty radiator/transmission. *tr

Transmission fluid is milky colored. loss of coolant. transmission slipping. somehow coolant in transmission fluid. *tr

I always take my car in for service at glendale nissan and so last year in july of 2013 i asked were there any recall on my car i was told no. so in feb of this year2014 i started experiencing some problems with me heat inside the car. they checked it and told me my transmission fluid was mixing with my coolant and i needed to replace both and its gonna cost me $5600. i asked was there a recall on this and i was told yes and my car wasn't covered because of the mileage. i instantly got upset because i always take my car in for service to this dealership. i was told i could try to replacing the radiator and drain the transmission but that was no guarantee how long the car would work. i did just that ..now my car is staying idle while driving and it wont idle down for a period of time. i tried calling the 1800nissan1 number and explain my problem and they told me they can't help me and nothing they could do. this is so wrong! i've spent so much money at this dealership its ridiculous. ive replaced my computer, belts, hoses, spark plugs,oil changes,drain my transmission fluid.so much i cant even remember everything. if they know that this is happening to these cars and put out a recall for this how can they get away with this! im a single parent of 5 children there's no way i can afford this!! and this is my only car i have for transportation!! this is just plain wrong! they shouldn't be allowed to get away with this! *tr

My vehicle just completely shut down without any warning signs or previous issues. i have taken very good care of this vehicle and the radiator has a manufacturer defect that allowed transmission fluid to leak into the radiator causing catastrophic damage to my radiator and transmission that nissan will not take any responsibility for and will cost me upwards of $5,200.00 at least. *tr

Nissan refuses to fully cover the repair/replacement of a faulty radiator and transmission. nissan is currently under investigation for this neglect and is stalling on recalling the vehicles. nissan extended a warranty leaving the burden of $3,000 deductible for the consumer. this is an appalling and sad excuse of customer service - the vehicles did not meet quality control and it is disgusting to have the customer put out that much money for a problem that existed before the vehicle left the dealership. *tr

The truck began shifting gears very roughly and slowly with a strong jerking motion to the truck. when taken for diagnosis was told that the transmission fluid and coolant were mixing due to a faulty radiator and thus got into transmission causing the need for replacement of radiator, flushing of fluid lines and transmission replacement approx. cost $6000. after researching this problem, i see multitudes of other nissan customers have had the same problem. this issue is extremely unsafe on roads. my car falls outside the extended warranty given due to this problem. in addition, if my pathfinder did fall under the warranty, nissan only assists with payment to replace radiator not the damage done transmission because of the faulty radiator. this absolutely needs to be investigated further! *tr

The fluids of the radiator and transmission mixed. 3 mechanics and a nissan dealer said its a known issue between 2005~2007. and no recalls we're being issued. i had a diagnostic test done at antwerpen nissan done when my pathfinder was running. i have had a 95 sentry, i have a 09 versa, i have talked my mother in law into a nissan altima, as well as my step mom. my husband has talked a couple of his co workers into a nissan also. i want to know why there has been no recalls on a "well kept secret" as that is what i was told. *tr

Radiator cooler leaking water into transmission,and transmission oil into cooling system. transmission stuck in 3 gear, engine overheating due to sludge inside radiator, a total disaster for a low income individual trying to make ends meet . *tr

Vehicle has not been warming up for about 2 weeks, never thought it was anything serious, thought it would be a heating coil or something, took it to the dealer on 1/3/14 to get an oil change and for them to look at the problem and the technician came back and said "oh you need a transmission and radiator bring the car back on tuesday" like it was something common. just looked into the complaints did not know this was a common issue with the vehicles, needless to say this will be my last nissan. i purchased a extended warranty which they did ask me, however i did not know about the class action suit that would have covered the issue until today 1/8/14. *tr

My car started to rattle and lose power at 45 mph. i drove it home and tried to reverse it in with no luck. i immediately knew i had a transmission issue. i parked the car for two days and took it to the dealer who later informed me that my radiator coolant fluid had mixed with my transmission fluid and destroyed my entire car. they quoted me between 7000-9000 to fix the car. i contacted nissan who informed me that there is nothing they can do because they extended the warranty twice to up to 100,000 miles. i find this ironic since after extensive research the issue usually occurs after 100,000 miles. nissan has know about this problem for 7 years and has chosen to ignore the issue and not issue a recall. now the consumers have to foot the bill.

I was on expressway, driving approximately 60-65 miles per hour and without warning car lost all its ability to accelerate or maintain speed. car engine would rev when you pressed on the accelerator but the car would not respond. vehicles behind me had to hit on there brakes and go around me as i attempted to steer vehicle to the side of the expressway. once vehicle came to a stop, my transmission would not engage in any gear leaving me stranded. i had to have vehicle towed to my home. i was informed by nissan that engine coolant had leaked into my transmission and ruined my transmission. i have since found out this is a common problem on nissan pathfinders and the cost to repair vehicle is between 4 and 5 thousand dollars. *tr

The vehicle vibrated and shuttered and ceased to move. i was in traffic and luckily had a place to pull over. i had the vehicle towed to the local nissan dealership. after a discussion and diagnosis by the technician and shop foreman it was determined that the transmission and the radiator had crossed contamination of fluids resulting in the transmission becoming inoperable and requiring the transmission and radiator be replaced. the shop foreman stated that nissan knew about this defect in the radiator and the resulting problems. i am waiting to find out if nissan will help with repair cost. i was told by the shop foreman that the cost to replace the transmission and radiator would be approximately $8,000.00. . *tr

Tl* the contact owns a 2007 nissan pathfinder. the contact stated that after attempting to accelerate, the vehicle hesitated to move. the vehicle was taken to the dealer. the technician diagnosed that the radiator fluid had leaked in the transmission. no repairs were made and the vehicle became inoperable after some time. the manufacturer was made aware of the failure. the failure mileage was 135,000. updated 12/01/14*lj *js

Radiator failed (product defect, no accident or external causes) and leaked into the transmission, effectively destroying it. had to get both radiator and transmission replaced. symptoms started with shuddering during shifting, which led to rough shifting, gear slippage, check-engine light, and eventually the car not even starting. *tr

This is all after the vehicle was serviced (by nissan dealer) for the known radiator leaking coolant into the transmission fluid. repair back in may 2013 with approx. mileage 68000. now vehicle has about 75000. driving home from dinner with wife in moderate traffic. herd a clunk and car would not accelerate. barely made it home. i let vehicle cool down and removed the radiator cap and found thick cream like fluid which is a definite sign of oil based fluid contaminated with water / glycol. seems to me that nissan did not replace or fix the leaking radiator. driving a vehicle that behaves in this manner can not be safe to drive. back to the shop (dealer) tomorrow. *tr

While driving the vehicle had a sudden loss of power and the service engine light came on. a local nissan dealer has informed me that due an apparent known issue for this vehicle a total failure of the transmission has occurred. the needed repairs estimate is $7,800 for a new transmission, radiator and electronic components. *tr

Vehicle began to vibrate at speeds of approx 45 mph. over a short period of time, the condition worsened - the vibrations became more aggressive and began to occur at higher speeds. after investigation by nissan, they advised that there was an issue with the radiator and possibly transmission that was no longer under warranty because i was outside of the 100,000 mile limit. the coolant is leaking into the transmission fluid cooler line and ultimately right into the transmission, thereby causing damage that may or may not be repaired with a new radiator and transmission. apparently, this is a know issue with these vehicles and nissan neglected to alert consumers. at this time, the vehicle is inoperable. *tr

This pathfinder is experiencing a failure with the transmission oil cooler / radiator assembly and is within the 10 year period specified by the extended warranty but is beyond the 100,000 mile limit. due to the nature of this defect, the severity of this failure, the repetitive nature of the failures and the limited or missing failure warning signs, i believe that an investigation is warranted. extending a warranty for a short period of time a limited mileage that most consumers breeze through in a few years in order to avoid a recall is not good for repeat business or safety. nissan settled a class action lawsuit where it identified the defective radiator, but capped the warranty at 10 years/100,000 miles. whether or not the incident happened at 10,000 miles, or 200,000 miles, it is still a manufacture defect, not caused by the consumer. simply extending the warranty coverage for the radiator without warning consumers of the consequences to the transmission only makes sense to me if nissan is looking to cut their losses. why didn't nissan warn consumers that the transmission could fail very quickly as a result of a cracked cooler tube? how many consumers must needlessly suffer transmission failures in busy intersections and on busy, congested highways before nissan does the ethical thing and issues a safety recall? this defect need not be left on the consumer's shoulders, and could very easily cause safety issues for the owner. *tr

I was driving my pathfinder down the highway and when i reached 40 mph, it began to hesitate as if the overdrive was not working. as i gave it more gas, it stopped. it has gradually gotten worse to the point that anywhere from 40 to 50 mph, the vehicle is hesitating unless you either slow to below 40 or speed up to above 50. i took it to the nissan dealer and he stated that the transmission fluid was mixing with the coolant, which means that i must pay to have my transmission replaced or purchase a new vehicle! i have since heard that there have been many reports of this same issue. my vehicle has gone out of warranty, but, if this is an issue that has been known for quite some time (years) as i have researched, then i believe nissan should have to cover the cost of replacement. why was there not a recall on the issue, which could have been fixed easily instead of having to replace the whole thing at the owners expense! i also realize that at any moment my vehicle could stop in the middle of the road, which could cause injury or even death to me or my family. *tr

Cracked radiator allowed coolant to leak into transmission so not knowing nissan was having this problem we had a new radiator installed and the cooling system and transmission flushed out mileage at this time was 79290 now 4 months later the transmission is shot and need a new one mileage now 83158 since the mileage is above 80000 nissan will not fix the car under there extended warranty and wants me to dole out 2500.00$. if i would have known nissan was having problems with there transmissions i would have taken my car to a nissan authorized service center the first time. *tr

Car loses power, shutters, has high rpm without acceleration, skips gears, stalls. had radiator replaced ($1,200), but didn't solve the problem. was told a new transmission is needed due to coolant mixing with transmission fluid and damaging transmission and components ($4,500). *tr

2007 nissan pathfinder with 86k miles. vehicle began hesitating when traveling 40 mph on highway, then loss of power sometimes. the car began to overheat. took it to a mechanic who told me that it was the transmission and radiator. cooler line had failed and mixed with transmission. i called nissan and was told that they extended the warranty to 100k but i would have to pay $2500 out of pocket. learned of a class action lawsuit in 2012. nissan never notified me of the transmission problem. if they had notified me on time, i would still be under the 80k warranty. i have no money to fix my car and now i'm stuck paying for a car that i can't drive. *tr

2007 nissan pathfinder le - 92,000 miles est. - i bought this vehicle new in 2007 and have been very pleased up until the past two weeks. my story is the same as others - transmission started getting rough, particularly around 45-50 mph and on inclines. there is an audible and jolting clunk moving from neutral to drive. while driving in the above range, the vehicle sounds just like driving over a rumble strip on the highway. i haven't even taken the vehicle in to the dealership yet, and i already know what the problem is. this car has been babied for years being that it is the sole automobile that my wife and kids drive in. i'll be [xxx] if i'm going to pay a $3000 deductible for a defect that nissan has had full knowledge of for years now! to[xxx] with the settlement that left most of us out in the cold while padding the pockets of the attorneys! it is time for the nhtsa to step up and make the only right and safe decision that nissan refuses to make! these cars are not safe to drive on the road in this condition! mine will remained parked in the drive until nissan is forced to recall every vehicle with these faulty radiator/transmission issues. this is my complaint. i hope that nissan does the smart thing here. they have lost me as a customer for life, and i've owned or driven over a dozen nissans in my time. it's a shame that this company will sit back and let these complaints mount up until truly forced to do something about it. they should be disgraced knowing that right now there are mothers & children driving in vehicles that could suffer complete transmission failure at any point leading to injury and death. my advice to all is to bring this to their doorstep. technology offers us the ability to bring the fight to the top of the food chain. i'll be bombarding email addresses and voicemail boxes until this is resolved. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

Radiator failed, leaking antifreeze into transmission. this mixing of antifreeze and transmission fluid caused transmission to fail my pathfinder is now in a parking spot. i owe payments on a vehicle i can no longer drive, nor afford to repair. *tr

Radiator failed, leaking antifreeze into transmission. this mixing of antifreeze and transmission fluid caused transmission to fail. the violent vibrations and rough shifting is a safety hazard and nissan should recall all models with this radiator. i had to pay $2500.00 to have this defect repaired. *tr

The radiator and transmission has appeared to fail in my nissan the radiator started to leak several months ago and i finally had to replace the radiator and now the transmission has started fail. the car has been well cared for and both the radiator and the transmission appear to be failing well before a normal radiator and transmission should. *tr

Transmission failure while driving in traffic. caused by ruptured coolant line, coolant mixed with atf. replaced radiator and flushed transmission, but damage was already done. *tr

There is a known defect in the radiator/radiator coolers in the '05, '06 and '07 nissan pathfinders which causes the radiator and the transmission to fail. please help with a recall on this problem, several of the folks still have a payment on the vehicles. you can see all of the problems that folks are having. thanks, terry please try to do all you can for all of us, i can't see that nissan can get by with this. they are just to replace the defect parts. *tr

Transmission starting slipping then started jerking while driving then it started overheating. took it to a nissan dealership because i bought the extended warranty that was supposed to cover the powertrain. they told me that the cooler cracked which caused the radiator fluid to leak into the tranmission and messed up the radiator, which is not covered by the powertrain warranty because the radiator cooler was not part of it. the dealership wants to charge over $6000 to fix it. *tr

My nissan pathfinder radiator coolant leaked into the transmission, i got an extend warranty and now the extended warranty is not covering it due to radiator coolant leaked to the transmission and it not a cover benefit now i'm screw. *tr

While driving on street around 2 pm, the car just lost its power and i end up stuck in the middle of the street with my 2 kids at the back seats, the car wont moved and i need to call for help so the other driver helped me push the car on the side of the street. tow truck arrived and towed my car to the nearest shop and found out that it was the transmission mixed with water coming from the radiator. it cost 2800 for everything. the current miles when this incidents happened is 111200. *tr

I took my 2007 nissan pathfinder to the dealer to have the brakes worked on and while there they performed a multi point vehicle inspection. from this inspection they informed me that there was cross contamination of the coolant and transmission fluid due to a failed transmission cooler. they indicated that damage had already started and it would only be a short time before the transmission failed completely so i needed to replace the radiator and transmission under the extended warranty and there would be a $3,000 deductible cost. in talking with the dealership service personnel and researching online it is clear that this is a common problem and obviously a design failure which could be a safety issue if the transmission fails while driving due to this known problem. my family and i are thankful that just by chance the brakes needed work otherwise my wife and kids could have been driving and been at risk of potential injury if the transmission failed unexpectedly as has been reported by other nissan pathfinder vehicle owners. due to the number of failures that has occurred it is irresponsible for nissan to just extend the warranty instead of taking a proactive approach and actually notifying their customers of the problem and fixing the known problem under a voluntary recall. i urge the nhtsa to initiate an investigation and hold nissan responsible for their design failure and protect the public from the potential safety risk by forcing a mandatory recall to fix the problem instead of just waiting for failure which puts the consumer at risk. *tr

The radiator leaked fluid into the transmission cause damage to the transmission rendering it useless. this is a known design defect with the 2007 nissan. *tr

Failure of automatic transmission due to cross contamination of coolant fluid into transmission. *tr

Vehicle's transmission started slipping at certain speeds. got a trans flush hoping it would improve. problem returned. service engine light came on. took to garage and had a new wiring harness put on. problem returned. got stranded and had vehicle towed. determined that coolant was in the transmission fluid. huge repair bill. part of the class action suit now but am still out $2500. probably started occurring before 80,000 miles and had i been more investigative at that time, bill would have been covered because it was under 80,000. now it's over that amount and i am out of luck. huge disappointment in nissan! *tr

The automatic transmission in the vehicle began to shift roughly. it was determined through the nissan dealership that the radiator had a crack in , and radiator fluid was leaking into the transmission fluid. it is a design flaw. *tr

My vehicle was shifting weird when all of a sudden it violently lurched forward while in traffic. i took it to the transmission repair shop and was notified that my transmission had coolant in it and needed to be replaced. this will cost over $9,000 to repair and the safety issue is that the vehicle lurching forward so violently is unacceptable because of the faulty transmission cooler etc... *tr

Was told that radiator coolant was mixing with my transmission fluid. i noticed first that the heater wasn't getting very hot a few months ago, but since i live in texas, this wasn't a huge deal for me since it's not that cold and so i was going to have it serviced at my next regular oil change. however, then just a couple of days ago, i noticed that the car would shudder around 45 - 50 mph so i took it in immediately and was told that i was experiencing a known defect of nissan's built between 2005 - 2010. if i had known about 3 months ago (about the time i started noticing the heater issue) i would've been fully covered under their extended warranty of 80,000 miles for this particular defect. but i'm at 84,000 and therefore have to pay $2500 out of pocket for a new transmission and radiator. i feel that i should still be covered since i started experiencing issues before 80,000 miles but i had no idea that it would be such a huge problem that would require a new transmission and radiator on a car that is only 7 years old... *tr

Tl* the contact owns a 2007 nissan pathfinder. the contact was driving 50 mph when the transmission began to jerk without any warning. the vehicle was driven to a safe location and inspected. the vehicle was taken to an independent mechanic who advised that the radiator coolant leaked into the transmission fluid, which contributed to the internal damage of the transmission. the vehicle was not repaired. the manufacturer was notified of the problem. the approximate failure was 110,000.

Transmission began shuttering, not up shifting and limited acceleration and speed on freeway at 55mph. turns out that the transmission oil cooler lines had been leaking anti-freeze into transmission and destroyed it. manufacturer has replaced with same cooler and rebuilt (not new) transmission. issue still exists intermittently. needs recall enforced. manufacturer is pricing same cooler and rebuilt transmission at over $7000. then agreeing to only charge $2500 - $3000 per class action settlement. outside independent repairs quoted at $350 for cooler and less than $2000 for rebuilt transmission. gov.'t recall should cover all new and re-designed parts. failures will and are occurring again. can result in accident at high speeds. *tr

Dealership states that transmission needs to be replaced as well as radiator due to manufacture defect. repair not allowed under warranty due to mileage. told that repair would be $10,000. *tr

Left motel at 7am, vehicle seemed to have trouble shifting, high rpm..pulled over to check..would not start..towed to dealership. *tr the consumer stated the radiator failed. updated ivoq 01/14/13

Transmission failure from radiator fluid leakage into the transmission fluid. the cooling system for the transmission runs through the radiator. when the radiator fails radiator fluid leaks into the tranny fluid and destroys the internal transmission clutch plates and torque converter. nissan extended the warranty from 36k to 80k miles or 8 years on the radiator, knowing there was a problem, but no notice from them to owners of this problem. when the problem starts, it is too late, resulting in $6800 - $7500 in personal expenses to replace the transmission and radiator. nissan will not consider fixing after 80k miles. i have 127000 and only 5 years old vehicle. this problem was acknowledged to affect 2005 - 2010 pathfinders. there are hundreds of complaints on this issue on forums, which i find after i have the problem. nissan should recall the radiators and fix the problems. it is a defective $300 radiator that damages a $7000 transmission!... this is unfortunate and irresponsible for nissan and is basically a band-aid on a serious hazard. now my $30,000 vehicle is worth $3,000 to the dealer for trade in. *tr

While driving i noticed a grinding sound when i reached speeds of 40-45 mph. when i pulled in to park the vehicle there was a loud grind and then the vehicle would not start. after checking the fluid levels i found that the engine coolant and the transmission fluid were mixing. *tr

Crack in radiator that was installed by nissan leaked into transmission. driving down road it got stuck in high gear. *tr

Tl* the contact owns a 2007 nissan pathfinder. while driving 50 mph, the vehicle shook violently. the contact released the accelerator pedal and had to accelerate again very slowly. the failure occurred multiple times. in addition, the air bag warning indicator was constantly illuminated. an independent mechanic stated that there was cross contamination with transmission fluid leaking into the radiator and coolant entering the transmission. as a result, the transmission failed. the radiator was replaced and flushed; however, the failure persisted and the radiator had to be continuously flushed of transmission fluid. additionally, the contact asked the dealer if the vehicle was included in nhtsa campaign number: 08v690000 (air bags), but the dealer stated that the recall was nonexistent. the manufacturer was not notified. the approximate failure mileage was 80,000.

Tl* the contact owns a 2007 nissan pahtfinder. the contact stated that while driving 40 mph. the radiator failed. the vehicle was taken to the dealer, who stated that the radiator, water pump, radiator thermostat, and transmission were damaged due to leaking radiator fluid. the dealer also stated that radiator needed to be repaired. the contact stated that this was the second occurrence of the same failure. the vehicle was taken to the dealer who diagnosed both failures. the manufacture was notified and offered no assistance. the failure mileage was 71,000 and the current mileage was 122,000.

I have maintained my car. in june, my nissan dealership charged me $1500 after i reported a jolt in the transmission. i brought it back 08/10/2012 and they said the transmission needed replaced. i took it to another shop and they said the radiator fluid had leaked into the transmission and ruined the transmission presenting a financial burden and a huge safety issue. *tr updated 09/13/12

I understand now that nissan pathfinder owner (05-07) have experienced issues with the transmission failing due to defective parts. i now have to have my transmission and radiator replaced to the tune of $7000+. why has there been no recall for this problem? *tr
