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

Another classic story of nissan pathfinder transmission failing due to engine coolant leaking into the transmission fluid cooler system resulting in catastrophic failure of the transmission. *tr

I purchased my 2006 nissan pathfinder in 2013 with 109k miles on it. i loved it for 1yr and a half. 2 months ago it started shifting rough, i took it to a local place to be looked at. i was told that nissan pathfinders have a faulty radiator that leaks internally into the transmission causing complete transmission failure! would cost $3600 to fix. i called suntrup and was told by the service department that they had never heard of this before and to bring it in, which i did and $100 later they told me the same thing i already knew from the other place for free. they again said they had never heard of this happening before but they could fix it for $6800! i began searching (not too difficult since it is all over the internet!) i called around trying to find a more affordable transmission place and every single place i called knew about the nissans faulty radiators!! this is a prevalent problem for the years 2005, 2006 and 2007 pathfinder, xterra and and frontier! nissan refuses to do a recall stating it isn't a safety issue but there was a class action suit closing in 2013 (year i bought my car) and would fix the transmissions up to 100k (i bought mine at 109k. the national transportation safety board is looking into this issue. i did contact suntrup and talked to the sales manager who said to come in and they would "try and help me". their solution is to roll the $4,000 i am upside down into a brand new car causing my payments to go up exponentially! (also as a single mom of 3 kids in car seats a car isn't helpful, neither is super high payments). you can not tell me that they didn't know about this nissan transmission issue being a nissan dealer! they didn't know about the class action suit, the year i bought the car?!?! perhaps there isn't anything that can be done in my case but i do not think it is ethical to continue selling these models and years!! *tr

Fluid cross contamination from radiator to transmission causing hesitation during operation of vehicle. per nissan service department,unless transmission and radiator are replaced this is unfixble and car will soon die. repairs estimate is 6,000 dollars. *tr

Leak in radiator causing cross contamination between radiator and transmission fluids. this is causing hesitation in power during operation of vehicle. per the nissan service provider we took it to, the cars needs a new transmission and radiator at the cost of $6000 or it will soon die. we believe this is a manufacturer 's defect and a known flaw- many other complaints are posted by other owners. *tr

The car is not heating up. the transmission fluid and radiator fluid is mixing together making a pink color.. we have had it only for less than a year. we have loan on the car. i keep seeing online that even after replacing the transmission. more problems keep happening. i looked up the vin number and it's saying our car make is recalled for the air bag? is there anyway you can help us or could we just trade to get a different vehicle. i would much appreciate someone to help. *tr

Tl* the contact owns a 2006 nissan pathfinder. while the vehicle was at the dealer for an unrelated issue, the technician discovered that the vehicle needed a new transmission. the contact stated that the radiator leaks coolant onto the transmission, which caused corrosion. the vehicle was not repaired. the manufacturer was made aware of the failure. the failure mileage was 93,000.

My nissan pathfinder was not heating/ defrosting...also, there was excessive noise when the truck was shifting gears. i brought it into my mechanic who told me coolant was leaking into the transmission, and the transmission and radiator would need to be replaced at a cost of approximately $4400. *tr

Tl* the contact owns a 2006 nissan pathfinder. while driving 30 mph, the vehicle stalled. the contact was unable to restart the vehicle. the vehicle was towed to a dealer where it was diagnosed that there was contamination of radiator fluid in the transmission and that the transmission needed to be replaced. the vehicle was not repaired. while the vehicle was previously in park, there was engine oil leaking underneath the front end of the vehicle. the vehicle was taken to the dealer where it was diagnosed that the radiator was leaking fluid into the transmission and that the radiator needed to be replaced. the vehicle was repaired. the manufacturer was notified of the failure. the failure mileage was 90,000.

I am the owner of a 2006 nissan pathfinder with current mileage of 106,000. i just learned today that i will have to replace the transmission and radiator for $6000. due to this known product defect. i am infuriated as i read through all the post by people like myself who have been told nissan will do nothing since the vehicle is over 100,000 miles, especially since the problem does not show up on average until 95,000 miles or more. it would appear nissan who just reported billions for their earnings could have done the proper product recall of all units manufactured/effected regardless of mileage and fixed the issue! *tr

Transmission failure due to radiator coolant mixing with transmission oil: reading other similar complaints about 2005-2010 pathfinder on carcompalints.com, i am wondering if there is a $90 solution to bypass the original setup and have a separate radiator for transmission, why couldn't nissan do it or atleast inform all owners about it so we could have avoided spending 4-5k on repairing something that is manufacturing design defect. i am in no way claiming to be a mechanic, but i am assuming other vehicles also have a similar setup, even other nissan models. how come this is the problem only for pathfinders? this is a design flaw and there should have been a recall instead of a class action lawsuit, but i guess our government is too busy looking out for special interest lobbyists. i am disgusted in nissan's conduct and also the conduct of nhtsa & cas who did not do anything when there was class-action lawsuit to prove these were not isolated issue with a few vehicles, but a design flaw. as is evident from multiple complaints on www.carcomplaints.com, this problem mostly occurs around 95k+ mile mark and by that time the extended warranty offered by nissan as part of their class action lawsuit is over. the settlement is an admission of fault on nissan's part and nhtsa/cas should force nissan to issue a recall or have them pay for the full repair of all affected vehicles and have them provide a remedy such as separate cooling system for transmission for vehicles which have not experienced this problem yet. *tr

Radiator failed and cross contaminated transmission with anti-freeze and transfluid. replaced radiator and flushed transmission in sept 2014 and three months later dec18, 2014 the transmission failed. repair center said it will cost $4500-$5000 for repair of transmission. *tr

Transmission went out all of sudden as i was driving on busy highway. was unable to get speed, coolant is gone as well. *tr

Leaking coolant caused transmission failure. *tr

From dead stop at stop sign, pushed on gas with resultant "grind" of transmission. happened 3 more times over the course of 2 weeks. took into dealer. transmission failure due to cracked radiator leaking coolant into transmission. known problem with certain nissan models. nissan only did an extended warranty that tapered off every year/10,000 miles. after 100,000 miles no help. this was not a result of worn out transmission, this was a result of engineering/manufacturing defect and should have been covered by nissan 100%. *tr

Coolant leak into transmission rendering vehicle useless. out of pocket cost was 2500.00 based off of class action suit. nissan picked up rest. found hundreds if not thousands of similiar complaints in this regard. *tr

Without warning the radiator leaked coolant into the transmission cooling part of the radiator and caused an almost instant burning of the transmission failure that was found to be ruined before i could even safely stop and have it towed. the car lost temporarily lost power to the rear wheels and stranded me in a dangerous intersection where i was almost t-boned. there was no prior symptoms until the transmission failed..... *tr

My radiator is evidently cracked, leaking coolant into my transmission, causing failure to shift. my vehicle began losing power. at one point, i attempted to accelerate through an intersection from a stand-still as the traffic light turned green. i was nearly rear-ended by the vehicle behind me as my vehicle was not moving, like being stuck in neutral. *tr

Have a 2006 nissan pathfinder le and noticed the transmission was starting to make a rumble strip noise around 45 mph. did some research and discovered that nissan had a defective radiator which caused anti-freeze to leak into the transmission through coolant line. knowing that the radiators were defective why wasn't nissan ordered to recall them. it is a safety hazard if you are traveling on the highway and your transmission fails!!! i now have to pay $2500 to pay for a known defect to have radiator and transmission replace. *tr

Fluid from radiator leaked into transmission, completely burned out. *tr

Had issue with transmission.brought to mechanic and found out that radiator was cracked and ruined transmission. was told by mechanic that this was common with this vehicle.went in internet and found all kinds of info about same problem. i feel if i was notified from nissan earlier i would not have to pay for extended warranty 2500.00.would have been free for under 80,000 miles.my car has 80,743 miles.not happy with nissan,will not ever buy another. *tr

Same issue as all others, drive a 2006 nissan pathfinder and was happy until 125tsd miles never a big repair. now i have the same issue faulty radiator kills silent the transmission. did visit the dealer for every service even as the problem starts little by little. first a unpleasant shifting, dealer recommends a transmission flush before the official service interval, done. after we are still not happy as we can tell the transmission shifts different as we did know it from before. see the nissan dealer again, they write the order with the customer complaint, ?customer complains about transmission problems?. written statement of the dealer, transmission checked no issues found. some miles later, total fall out of the transmission special the tcu. good customer will not see now dealer again but a lawyer. *tr

Service engine light is staying on. took to dealer and ses code read catalytic converter needs to be replace. did some research online and looks like this is a common problem 02 sensor does not report airflow. $1200 dealer repair. not sure why there hasn't been a recall. *tr

Tried to sell the car and the buyer pointed out that the radiator must of cracked and mixed with the transmission fluid. he did not buy the car and now i am being told that i have to replace the transmission and the radiator. apparently this is a huge problem on these cars and they need to fix this. very upset and will never buy a nissan again. *tr

Car started rumbling very erratically at high speed. had i not had good grip on wheel it would of been bad for my family or others. glad it didn't fail completely leaving me powerless on highway. i believe this will result in deaths or serious accidents. not to mention thousands in repairs. had radiator replaced last year due till same problem. something needs to be done. this always happens right outside if the extended warranty. *tr

I was driving yesterday night when my car started jerking and stopped suddenly on the highway, thankfully the cars behind me were able to stop avoiding a crash because there was lots of traffic, but otherwise, this would have been a fatal crash. the car would not move for several minutes, people had to help push it off the highway. then after a while it started moving again. i was able to drive the car, jerking all the way back to my house. i had previously noticed a jerking whenever i am accelerating or decelerating, i took it to the dealership and they informed me that it was an issue with the transmission of pathfinders owing to a defect in manufacture that causes radiator fluid to mix with coolant affecting the transmission. they flushed the transmission but the jerking continued. i was searching the internet on this and saw many complaint on this. this issue need to be resolved. i am glad i was spared but life's are being put in danger. *tr

Engine coolant hose ruptured into the transmission fluid. first noticed it when the engine was running hot. found out this is a factory defect. *tr

Radiator developed a crack which leaked into transmission - both had to be replaced. we were told, due to a class action settlement in 2013, we were responsible for a deductible of $2,500 since our vehicle started problem after 80,000 and past march 1, 2014. did not realize this problem until we took vehicle in, by that time mid april 2014 and at 81,990. this should be a recall. *tr

Corrosion in radiator parts allowed coolant to contaminate transmission fluid resulting in failure of transmission. *tr

Fluid from radiator leaked into transmission which destroyed both. *tr

Took my car in for brand new tires..mechanic attempted to start my car, but failed. had to get my car towed to a nissan dealership and they stated 24 hours later after receiving my car i will need a new transmission and radiator although my car was maintained and always serviced. they stated i will need to pay $6,000 for repairs to drive my car. right now i am paying a car note and can't drive my car. *js

Sudden jerking in vehicle when traveling at highway speeds. the problem has been diagnosed as a failed transmission cooler which allows coolant to mix with the transmission fluid, causing internal damage to the components. *tr

Auto transmission/radiator.

While driving transmission began shifting erratically. after stopping at a traffic light the vehicle would not accelerate above 20 mph. while attempting to get the vehicle home smoke was noticed coming from the transmission. inspection verified transmission fluid was contaminated with coolant. *tr

Transmission: having problems with transmission - it will not go on reverse. researching on the internet i found that this is a manufacturer defect. the radiator would crack causing the coolant to mix with the transmission fluid. *tr
