Automatic Transmission Cooler Problems of Nissan Pathfinder - part 2

My transmission failed becuase the cooling lines that run through the radiator cracked allowing the coolants to mix. I will have to replace the transmission and the radiator.

I was preparing to merge onto the highway, I slowed down to yield to oncoming traffic. When the gap between oncoming cars was large enough I accelerated and proceeded to merge. Instead of accelerating my car began to rumble and move slowly. Instead of properly merging onto the highway it just slowly rolled into oncoming traffic. I became horrified and I was afraid to drive on the highway, and I had to reverse to back out. I took back roads to Nissan dealer. The car would rumble and vibrate and drive slowly as if it was stuck in 1st gear. Dealer determined that "transmission oil mixed with antifreeze" due to "cooler hose cracked and ready to break" rendering transmission incapable of proper operation. Nissan dealer replaced transmission, radiator, and flushed cooling system.

From stop transmission failed to engage. Checked fluid found water in transmission from failed cooling line thru radiator/ trans cooling line.

My 06 Nissan Pathfinder starting shaking and making a shuttering noise at 40mph. Also a squeaking noise coming from the undercarriage at lower speeds. I took my Pathfinder to the dealer to have it looked at. After a few hours the dealership called and told me it was a defect in the transmission cooler built inside the radiator. A line in the cooler cracked letting radiator fluid and transmission fluid to mix together and run all through both my cooling and transmission systems. I have 75,000 miles and was told I'm under the 80,000 mile warranty for these repairs. I was told I would need a new transmission and radiator along with a new thermostat and gasket. I'm one of the lucky ones that will not have to come out of pocket for these repairs. I've been reading post after post about other people having this same problem that are over the mileage warranty and are having to pay CO-pays and some that had to pay the full repair bill. Please recall this. There are too many people being affected with this issue.

Vehcile starting vibrating at 40mph, returned to the dealer and was informed transmission had failded due to raditor failure of transmission cooling system. I was aware of the problem with this paticular vehciled and it had been serviced on a regular basis with premiere Nissan in metairie, la. I addressed the issure with the service department several times prior to the transimission failure and was told there were no problems. I contacted Nissan north America and they refused any assistance with the $5,800 repair estimate. This should have been a recall of all vehicles when these problems were identified.

Transmission did not engage when pulling car out of my garage. I put it in park and tried again but the car would still not engage. After a third attempt the car began to move but the transmission was acting very odd and disengaging, almost like I was coasting. This was very scary for me and my three children. My husband inspected the car and found that radiator fluid contained a white greasy substance. I took the car in for inspection and repair at my local Nissan dealer and they informed me that there was indeed cross contamination due to a cracked transmission cooling line mixing with the radiator fluid. This will end up costing me $2,500. 00 to fix. It appears that I am not the first to have to deal with this problem, and by the number of people filing complaints it seems like a defect to me and not mere coincidence. This really needs to be a recall. Nissan needs to be held liable for the multitudes of people stuck in this unfortunate situation.

The vehicle started to lose power and come back on while traveling with 6 passengers on the 101 fwy in north los angeles county. Then it's guage showed it running hot (no smoke or loss of power) and a check engine light was on. Then the guage said it wasn't running hot and no power loss. I continued down the freeway and made it home with no more problems. I studied and research this problem for hours on the web. I brought the car to the dealer service department the next day. My research turned up valid. This 2006 Nissan Pathfinder se vehicle should have been recalled by the manufacturer. Nissan knew about this problem. Instead Nissan extended a warranty to 100k and passed these flaws on to the consumer. Shame on Nissan! the problem is what is described as a fluid intermix. This is because the transmission fluid has cooling coils that run through the radiator. For a year or two Nissan had produced defective product and was not forced to recall. Now me the consumer is stuck with a six to nine thousand dollar repair bill on my vehcile with 110k miles on it. Recall these vehciles please Nissan. Wiistle blowers just ask the service people about this particular no no Nissan did. This is consumer abuse by corporate tough guys.

Started as a vibration on 5ft gear at around 45mph. During a routine check, it was found transmission oil into the cooling system. Hence, the transmission fluid was contaminated with coolant, causing transmission malfunction as a result of a defective radiator.

Transmission coolant line in bottom of radiator ruptured leaking coolant into transmission and trans fluid into cooling system.

My wife drove the SUV to town. It started acting funny (transmission was not shifting correctly). At this time the SUV acted like it was out of drive and would not go forward or reverse. She had it towed to a repair shop to see what was going on with it. They called her later the same day and told her that her transmission cooling line in the radiator had leaked coolant into transmission. The Nissan dealership in longview, wa. Told us that we have to pay $2500. 00 if we want our SUV repaired, and that in October 2012 they had sent a letter stating that we needed to bring our SUV in because of this very problem. We did not receive this so called letter.

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.

The contact owns a 2005 Nissan Pathfinder. The contact stated that while driving approximately 55 mph, an unusual noise could be heard coming from the engine compartment. The vehicle was taken to an authorized dealer where the transmission was flushed and the radiator was replaced. The technician stated that the transmission exhibited internal damage as a result of coolant leaking from the radiator. The vehicle was not included in NHTSA campaign id number 10v517000 (engine and engine cooling) due to the fact that it had exceeded the 100,000 mile limit. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 100,720.

Tl- the contact owns a 2006 Nissan Pathfinder. The contact stated that while driving approximately 35 mph the vehicle suddenly stalled. The contact noticed the fuel tank was empty. After fueling the vehicle the contact attempted to accelerate but the vehicle failed to accelerate. The vehicle was towed to the dealer for diagnostic testing. The technician stated the radiator had leaked water into the transmission causing the transmission to fail. As a result, the transmission needed to be replaced. There was an investigation under NHTSA action number: dp12004 (power train: automatic transmission: torque converter power train: automatic transmission: cooling unit and lines power train: automatic transmission: control module (tcm, pcm)) that may be related to the failure. The vehicle was not repaired. The VIN was not available. The approximate failure mileage was 95,000. Pmb.

The contact owns a 2007 Nissan Pathfinder. The contact stated that the filter radiator caused the cooling to leak, which destroyed the transmission. The dealer was notified who stated that he was not familiar with the type of failure and offered no assistance. The manufacture was not notified. The failure and current mileage was 75,875.

My transmission failed while driving on an interstate. Mechanic said the cooling line cracked, which allowed radiator fluid to enter the transmission and destroy it.

Haven't finished paying off my car and already the transmission of my Nissan Pathfinder 2007 is failing. The radiator spilled the cooling liquid into the transmission, which then proceeded to cause serious problems to the transmission. The guaranty expired after 100 000 miles, even though prior to that the mileage the guaranty still applied. Now, in order to fix the transmission, or replace it for a new one, will cost me over $5000usd. I'd like to unite to the existing complaints/lawsuit against Nissan on the matter of the faults found in the 2007 Nissan Pathfinder, as I feel that is unfair that the company with the knowledge of fault in its product has not warned the public and has proceeded to sell the product to the public, leaving us with a faulty machine that in the end is more expensive, and not a satisfactory product. I am hopeful that the company will response to all of our complaints, stepping forward and taking responsibility for the inconvenience they have caused, and hopefully taking ownership of the expenses that due to their lack of responsibility, have been incurred on to us, the consumers.

Started noticing in March 2007 a noise like running over a rumble strip for brief periods that we thought were either our new tires or road surfaces. Later we noticed it started getting longer and it seemed liked it had a hard time shifting gears. We took it to our Nissan dealer who informed us that there was a leakage between the cooling system and the transmission which in time will cause the transmission to fail. We also found out they were aware of this problem,but we were never notified. Now they told us even with and extended warranty to 80k we were past that at 81k. I feel they should be forced back to up their known defects and issue a recall.

Car would not engage in reverse. The problem was diagnosed as my transmission failing due to design flaw that allowed radiator cooling fluid to leak into the transmission. I had to replace the transmission at a cost or $3,400. The car warranty had run out and I was not reimbursed by Nissan. Nissan has not recognized that they have a design flaw issue that is costing their car owners thousands of dollars in repairs as well as ruining their reputation.

Well my Pathfinder was working great and I never had any problem with it then one day I'm driving it to work and it just stop I kept accelerating and it wouldn't move. A friend of mine came and looked at it and told me on the spot you radiator busted and filled your transmission with coolant and that destroyed your transmission and destroy it did. My friend to told me funny thing is that could have been prevented by installing an external cooling which he would have done for 100 bucks if only had Nissan let me know that the 2005 Pathfinders had this issue. Oh well I feel cheated and I swore in my life I will have a Nissan car again or Acura for that matter nor anyone in my family. This one I'm stuck with but once guaranteed that the mechanic gave it's about to expire I'm selling it and I'm definitely not buying Nissan again! ever!.

The radiator colling pump cracked causing the cooling fluid to leak into the transmission and mix with the transmisssion fluid in return a new radiator drive unit and transmission needed to be replaced as well as the torque converter.

Heard a thud in the rear. Took it to get looked at by a mechanic. Before the mechanic even looked at it he knew what was wrong. I told him I think something is wrong with my transmission. The mechanic already knew what was wrong hooked it up to the computer. Didn't show anything he explained to me. The computer was not working on the car it had burned out due to the design of Pathfinder. The transmission oil the radiator and all of the cars fluids are mixed. The radiator looked like vasoline. He told me I need a transmission cooling system and computer. Hr would charge 5,000 dollars he suggested taking it to Nissan. He said he has fixed several pathifinders with the same issues he said Nissan is well aware of the problems. I took it to my dealer in bradenton FL. Where I purchased my car they quoted me 8,000 dollars to fix it. Since my truck isn't under warranty. I asked my dealer about all the problems. He told me to call Nissan to make a complaint there isn't any thing he can do. Then I researched and found thousands of Pathfinders with my same problem im appalled by this. And need to know what I can do????.

The radiator failed causing coolant to leak into the automatice transmission. Bother were ruined and had to be replaced. The repairs cost $5000+ this issue is well documented on top shelf internet websites including edmuands. Com and others. Many folks are under power when the engine stalls, at any speed. . Nissan is not offering recall. A class action lawsuit is underway. This is a dangerous design defect (cooling the transmission via the radiator) and people may be injured or worse. Maybe it has already happened to some?.

Transmission failure, radiator failure. Had it fixed months ago and my car continues to spew blueberry yogurt from cooling system. Nissan did nothing, dealer did nothing and now mechanic is making me jump through hoops. This is a serious and dangerous issue, occurring countrywide in thousands of vehicles. Nissan obviously does not want the bad publicity by owning up to the faulty parts. . . Why do you think they changed the parts in 08' models and up? luckily my tranny blowing on the interstate did not cause injury, but it very well could have. . . . Is it going to take someone dying for someone to finally do something!!?? there is currently a class action lawsuit against Nissan for this issue (since 2010!) do something!! innocent, hard working people are being put in danger by these vehicles.

The transmission on my 2005 Nissan Pathfinder has failed due to an apparent leak in the cooling system that allows radiator fluid to leak into the transmission. We brought the vehicle to the dealership as it began to make loud noises while driving, apparently struggling to shift gears, and sounded as if it was about to fall out of the vehicle. The dealership pretended that they did not know what was wrong with the vehicle until I brought them the research I had found online (which there is plenty pertaining to this same exact problem with this same exact make, model, & year vehicle). Then they finally admitted that they were aware of the this widespread problem but that unfortunately the vehicle was out of warranty and that I will now have to eat the $6,000 repair bill that they've given me. Based on the research I've done, Nissan corp. Has known about this problem for some time and has failed to address it.

Vehicle coming to a complete stop when the transmission control module failed due to an electronic short resulting from a radiator cooling line rupturing and flooding the transmission. This is a 2006 Nissan Pathfinder. I checked on line and was surprised (amazed) at the number of individuals who have had the same problem. There are even class action lawsuits pending related to Nissan knowingly aware of a defective radiator cooling line that breaks mixing into the transmission. My vehicle has been diagnosed by a Nissan dealership quoting $6,500 to replace the transmission and radiator. Nissan also extended the factory warranty to 80k miles when it was discovered that there was a defective part. Thank you. . . But, they never notified me that there was a problem. And, you don't know there is one until it fails and creates the problem. This is very dangerous. . . . As the car will die if the module shorts out. It is the same module that tells the electronic ignition system that the vehicle is in park. My opinion, Nissan being aware of the defective part, in collusion with a vendor who provided the part. . . . Is darn near not only fraud but conspiracy. I pinged several dealerships who openly advised of the defective part and the number of vehicles they have fixed. I asked the dealer how long to get a transmission. . . I was advised that the one required to fix the 2006 Nissan had 148 transmissions on back order. I should expect 4 to 6 weeks to get one. But, of course. . . My warranty is expired. . . . I was also advised that the line that ruptures normally does between 90 and 110k miles. This is not only a safety issue. . . It is down right fraud and deceptive practices. Deceptive, because of not notifying owners. . . . Fraud by knowingly having a defective part on a vehicle.

Due to a known manufacturing defect in the 2005 Nissan Pathfinder transmission cooling system, my daughter was stranded by a vehicle that wouldn't move. After researching the problem I have found that this is a fairly common problem in the 2005 year model. There is a problem with the engine cooling system and the transmission mixing fluids, thereby causing catastrophic damage to the transmission. Leading up to the transmission failure, the transmission may fail to shift or it may downshift at highway speeds causing overspeeding of the engine.

Nissan issued an extended warranty to replace faulty radiators and transmissions affected by these faulty radiators yet did not increase the warranty by the normal 12mo 12,000 mile instead they increased it to 96months and only 80,000 miles not 96,000 miles simply because most failures happen over 80,000 miles. They also claimed this was not a safety recall. When the radiator affects the transmission and the vehicle can stall during driving. How is this not a safety issue. This is from their letter informing consumers: "in vehicles equipped with automatic transmissions, a crack in the radiator assembly might occur at higher mileages leading to internal leakage of engine coolant. While the majority of vehicles will not experience this issue, Nissan is extending the warranty as it applies to the radiator assembly to demonstrate our commitment to stand behind our products and our customers. Nissan is extending your vehicle's new vehicle limited warranty as it applies to the radiator assembly and its component parts from 36 months/36,000 miles to 96 months/80,000 miles, including damage, repairs, replacement, and related towing resulting from this issue. "a crack in the radiator is caused from thermal schock. Which Nissan knew about before installing the original radiator in my vehicle. I know this because they applied for a patent on Jan 24,2006 which was published sept 2006 therefore they knowingly installed radiators that would undergo thermal shock ie crack. See the entire publication where they are filing for a patent recognizing the existing problematic radiators: vehicle cooling system,publication number us20060196634,application number us/11/337437,assignees Nissan motor CO ltd calsonic kansei corporation,inventors sato yousuke ishikawa takayuki iwasaki mitsuru filing date 24 Jan 2006publication date 07 Sep 2006. Make Nissan replace all defects.

I purchased a 2006 certified Nissan Pathfinder in 2008. I was guarrenteed 100k engine and power train warrenty. I currently have 96,426kmiles and the transmission gave out about 1 month ago in saline KS. I took the car to the Nissan dealer in kansas and was told that it would be covered. However after waiting over a month for the part Nissan stated that the transmission gave out because of the transmission cooling system leaking therefore the transmission is not covered. I have contacted Nissan corp directly and have received the same answer. This is hazardus because the transmission gave out without warning during a snow storm. Lickly the car mannaged to coast to the side of the road. I had my car shipped back to my home in clarksville TN. And was informed by the delivery driver that the parts were in the back of my car. So now I have a car that was taken apart but not fixed with a bunch of parts in the cargo area and about $2000 in debt for a rental car and shipping the car back too clarksville. Since I have had this problem I have found out that the transmission and cooling systems have been malfunctioning since 2004.

The contact owns a 2006 Nissan Pathfinder. The contact stated she was driving at 50 mph when the heater and defroster failed. The windows had to remain open in order to keep the windows from fogging. In addition, the contact stated the vehicle would exhibit an unusual increase in engine rpms intermittently. The vehicle was inspected by a local mechanic who advised that radiator fluid leaked into the inner cooling system and into the transmission, causing the heater failure. The mechanic performed a transmission flush and replaced the transmission filter and radiator. Within five months, the transmission failed. Additionally, the fuel level gauge would sporadically read inaccurate fuel levels, causing her to run out of fuel twice without warning. The contact referenced NHTSA campaign id number: 10v075000 (fuel system, gasoline: storage: auxillary tank) but was unable to confirm if her vehicle was included with the recall. The vehicle was not further repaired. The failure and current mileages were approximately 118,000.

Truck began to shudder as if driving on rumble strips, then overheated on major highway. The transmission fluid and cooling fluid mixed due to defect. Radiator had to be replaced and truck completely flushed several times. Good chance that transmission was damaged and will have to be replaced, also. Total cost of repair was $1500.

I have a 2005 Nissan Pathfinder se. I have had an issue with it and it could of been a safety issue. In June '09 the radiator had a cooling line that broke which has become a transmission problem. And anytime that a drivetrain is in issue it could cause a safety issue. I replaced the radiator for $600 and the transmission went out with violent stuttering and engaging in and out while in heavy traffic which could of caused a major accident especially at highway speeds. I have replaced the transmission with no help from Nissan. This is a major problem that has been documented by several hundred consumers all with the same problem. The total I spent was $3197. 09 which should be reimbursed by Nissan corp for this problem is well known by the yet no recall has been issued.

Noticed rough shifts in transmission, eventually failed to engage 5th gear. Took to dealer, transmission lines inside radiator had ruptured. Replaced transmission, radiator and lines at a cost of over $8000 and 4 weeks time. This occurred at 67k miles. At 87k miles, radiator fluid is milky and shows symptoms of another rupture of coolant lines inside transmission. Dealer and Nissan USA do not recognize this as a safety issue or inherent defect in engineering. However, a simple search will show an extremely large number of people with similar issues caused by faulty cooling lines in the radiator rupturing causing transmission abrupt behavior and the danger for loss of vehicle control due to the failure.

Tl-the contact owns a 2006 Nissan Pathfinder. The contact stated that while driving, the fuel gauge displayed an inaccurate fuel level reading, causing the vehicle to stall. The contact was unable to restart vehicle. The contact refueled the vehicle and was able to resolve the failure momentarily before recurring. The vehicle was taken to dealer who advised that the fuel sensor was defective. The vehicle was repaired by replacing the fuel sensor. In addition, the vehicle shifted out of gear abnormally. The dealer determined that the failure was caused by cooling fluid leaking into the radiator. The dealer then performed a transmission system flush and the failure was resolved. One year later after refueling the vehicle, the contact was unable to restart the vehicle. The vehicle was towed to dealer who inspected the vehicle and determined that the transmission module system had failed. The failure was due to a leak of cooling fluid into the radiator system. The vehicle was not repaired. The manufacturer was made aware of the failure however, no further assistance was offered. The failure mileage was 60,000. The approximate current mileage was 107,000.
