Automatic Transmission Cooler problems of the 2005 Nissan Pathfinder

The contact owns a 2005 Nissan Pathfinder. While driving 40 mph, there was an abnormal vibration to the vehicle. The contact stated that the accelerator pedal was depressed and the vehicle stalled. The vehicle was taken to the dealer where it was diagnosed that the radiator fluid leaked into the transmission. The contact was informed that the radiator, transmission, and transmission cooling lines needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 92,000. The VIN was not available.

After receiving a complimentary multi-point inspection from the local Nissan dealership, my wife told me that on the way home that the transmission seemed to not want to shift properly. Went to check transmission fluid and found that the dipstick is locked into place. Did some quick research to find out how to check fluid level and then found out about issue with Nissan Pathfinders radiators having a problem with leaking coolant into the transmission cooling system. Checked radiator and found frothing foam on the inside of the pressure cap indicating that the radiator had failed. Contacted dealership and asked them why the section of the inspection for the cooling system and transmission system were checked as "ok". Did not receive an answer. Also, we were never notified by Nissan about the issue with radiator in our Nissan. The vehicle is currently parked since the dealership said it would cost up to $3000 dollars in repairs under the agreement reached. I do not understand why this was not a recall. This situation could of caused a catastrophic failure of the transmission at speed while driving or catastrophic failure of the engine because of lack of cooling causing the engine to seize up at speed while driving.

Check engine light came on, and after bringing vehicle to Nissan dealership, they informed me that due to an internal radiator crack, that engine coolant had leaked into the transmission cooling coils and as a result transmission failure was imminent and that both the radiator and transmission would need to be replaced. Then they indicate that they had extended the original vehicle warranty due to the volume of such failures, and that they would make the necessary repairs for a meager $3,000 "copay". I laughed because I thought he was merely making a joke, but then found out that the joke was on the Nissan customers. Apparently as a result of a class action lawsuit settlement, Nissan had agreed to the warranty extension. What a slap in the face, to say that in lieu of recalling the defective radiator, and making a $500 repair, they decided to roll the dice with their reputation and their customer's wallet on a potential $3,500 to $4,000 repair. What a moron business decision. The second joke came, when I inquired about the warranty on the repair, and they informed me that it was only 12 months or 12,000 miles. What a vote of confidence in their $3,000 repair (copay ??). So for a few bucks more, I can have an independent shop do the repair, and get a better warranty. Insult # 3 came when they offered up, that alternatively, they would discuss buyer assistance on a new Nissan vehicle. They probably heard me laughing in japan.

I had the vehicle's tires replaced and within a few days there was a shudder like rumble strips. I took the Pathfinder back to have the tires looked at. Repair shop replaced the wheel bearings. The shudder still persisted. I talked to a friend who owns a transmission repair shop and he told me about the radiator leak/transmission problem. He said to check the engine coolant for milkiness and search online. The coolant is milky and after reading all the other complaints, my family is scared to use the Pathfinder. I think a recall should be issued because the transmission is failing because of failure of the cooling system not wear and tear. A failing transmission is more likely to cause an accident than a failing cooling system. Also, Nissan's extended warranty seems to end to early to be effective.

The contact owns a 2005 Nissan Pathfinder. The contact stated that radiator fluid entered the transmission cooling reservoir, causing the transmission to fail. The vehicle was taken to an authorized mechanic where a diagnostic was performed. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was 85,000 and the current mileage was 86,200.

I was coming back from the store and was waiting at a red light when my light turn green I had trouble going I press the gas and it was like pulling then it king of jump and the service engine light came on. I had a shop check my car and sure thing it was the cooling/ transmission problem. I have not driven my car since I have no money to pay for the repair, yes I take it out to turn it on and move around my block, but is that fair its my family car we have not gone anywhere else because we do not fit in to our. Smaller cars I did receive the claim form for this problem but I did not had the problem then the claim expired June 7th 2013, right before my problem. Please help us.

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

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 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.

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 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.

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.

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.
