Pathfinder 6-cyl

  • 86,000 miles


Not even 3 months after we purchased our used Nissan Pathfinder.I had just dropped my older children off at school and my car started to have a hard time. I knew I had to get my vehicle to safety. As I approached a intersection intersection on a very busy main route the car would not move at all. I was scared because the speed on that street is 50+ and I was stuck in the middle of the road with my 7 week old. After being towed and transferred to coastal Nissan in norwell MA. We were told about the "recall" and forced to borrow $2500 so that we could pay to have the vehicle repaired. Nissan told us it wasnt a safety complaint. I beg to differ! I was stranded on a busy street with a newborn if we were struck the outcome could have been horrific. I hope someone will finally do something about this problem!

I had transmission failure while driving. I lost all but 1st gear with no warning. I had it towed to a transmission shop whom stated that there was coolant in the transmission fluid. They advised me that the cooler in the radiator had broken and allowed coolant to mix with the transmission fluid. I have not got a bill yet but it will be upwards of $3500. I had gotten two letters from Nissan that extended the warranty but both times I was to high of a mileage. Seems that if they extend a warranty for a problem twice than they know they have a problem and should do a complete recall. I also had the fuel sending unit go out and I repaired that due to Nissan wanting a high dollar amount to fix it. I have had it with Nissan and them not doing anything to help the customers when they know there is a major problem.

Radiator fluid has leaked into my transmission, due to a factory defective radiator. My transmission is damaged and will not shift into 5th gear. The transmission will have to be repaired or replaced along with the radiator.

I noticed that the temperature gauge was reading a little high so I took it to a friend and he said there was oil in the radiator when the cap was removed. He recommended that I take the vehicle to the dealer. The dealer said I had to pay a co-pay of $2500 to replace the radiator and the transmission because the warranty had expired.

  • 110,000 miles
I was driving the car and when on the onramp of the freeway, the car lost power and shut down. Nissan dealership said the radiator leaked fluid onto the transmission causing it to loose power. They said I need a new transmission and radiator but will not cover the warranty which was settle in us district court of New York. They want to charge me $5300 for the repairs. This is clearly a faulty design of the Nissan Pathfinder series and website searches verify that the problem exits for thousands of Nissan Pathfinders for the years of 2005-2010 in relations to a radiator crack and fluid leaking onto the transmission.

Transmission just out of no where starts jerking and over heating took to the dealership and they told me that coolant/transmission fluid cross contamination due to internal radiator/transmission fluid cooler failure to fix the problem it will cost $4700 after doing some research have found that there is more Nissan owners having this very issue please Nissan you need to do a recall on these transmissions if not ill never buy a Nissan ever again. I mean who has that kind of money to spend on a part that is internal and not able to be maintenanced how do we know its going bad? oh yea it just stops working I have a family of 5 and we travel the interstate alot im glad I wasn't on the interstate at this particular time. Could have been very tragic if some one hit us because of a malfunction like this.

Pathfinder 6-cyl

  • 136,000 miles
I am an owner of a 2005 Nissan Pathfinder. On 12/05/13 the transmission and radiator on my car failed with no warning on a deserted road. I had my car towed to Nissan where they told me that it would cost 5,100 dollars to repair. I later learned that there had previously been a lawsuit against Nissan for transmission and radiator failure and the make and model of my car was included. After learning this information I called Nissan back and they stated that they only covered it up to 100,000 miles and my car is at 136,000 miles so it would be my responsibility to fix it. After doing research on line there are so many other people that are having these exact same issues and Nissan will do absolutely nothing about it and they are not willing to help with cost in any way.

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.

My family and I were driving home. We live in the mountains of wnc and as we were heading up and incline the transmission slipped and after much research I believe I am the owner of a Nissan vehicle with the transmission/coolant issue involved in the class action lawsuit in NY. However, because my vehicle has 154,000 miles on it and the issue just occurred I am unable to join the lawsuit. I still want you to be aware that this issue has no deadline on it and Nissan should be held accountable for every defective vehicle still on the road regardless of age and mileage. If the problem is specifically attributable to the defective radiator and Nissan has not fixed it then Nissan sold a defective vehicle, period. Had this defect not been built into the vehicle I am sure it would be operational right now. I also own a 2001 Chevy cavalier with over 200,000 miles and it is still running!!! shame on Nissan!!!!

They report in all instances that the dealer diagnosed the problem as a failed transmission fluid cooler located in the radiator assembly that allowed coolant to mix with and contaminate the automatic transmission fluid, resulting in damaged internal transmission components and a damaged internal transmission computer. The complainants report no warning signs leading up to or just prior to the failures.

  • 86,000 miles
Due to a design defect, I have radiator fluid leaking into and ruining my transmission. I learned that Nissan has recognized the problem and has extended the warranty. However, because the vehicle has above 80,000 miles I have a co-pay of $2,500. I find this unfair. This problem is not due to miles driven or operator error. This is a design defect and to require customers to pay thousands to fix Nissan's engineering problem is wrong. I feel I have been taken advantage of. Nissan should cover the full cost of the repair regardless of mileage because the problem results from a design flaw.

Pathfinder 6-cyl

  • 80,000 miles
I experienced transmission shifting problems between 50-60 mph. Local service center diagnosed it as a defective radiator which allowed radiator fluid to get into the transmission fluid. After talking to other Pathfinder owners and checking the internet apparently Nissan was aware of their defect and tried to keep it hidden resulting in a class action lawsuit which was settled. Unfortunately I am out $1,500 for repairs and there is no guarantee I won't be replacing my transmission soon! can you help?

As I was driving on a motor way, the car just start shaking and stopped in the middle of the road without prior warning from the dashboard. A message "service soon" started display on the dashboard. This seems like a transmission failure. I couldn't move the car from that spot on the motor way. I had the car towed to the mechanic and he diagnose the car and couldn't find any fault on the car. I am scare to drive the car and the car is still at the auto mechanic shop not know what the problem.

Sudden jerking in the 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. Nothing happened before, but the transmission started slipping 5th gear and no going into it, now 4 and third finally just stopped moving... repair cost is going to be 6500$ at the Nissan dealership and they will not admit a known issue....

Pathfinder 6-cyl

  • 109,000 miles
My car would not start one morning so I had to call a tow truck to take it to my mechanic, he called me to tell me that the radiator was allowing moisture or water to go into the electrical part of the transmission and the transmission has completely fried. I got a quote of $4000 to $6000 to fix or rebuild it. He then told me there are thousands of articles online about the problem and that since my car was at 109,000 miles there was nothing Nissan would do about fixing it even though there was nothing I did to cause the problem!!! I still owe $8500, as I have only had the car for 2 years, and I sure can't go buy another car. I have 3 small children so now I have no car, can't afford another and Nissan will do nothing to help.

I was did a click sound when changing shifts from 1 to second. I took the mechanic and I was told the transmission had leak some fluid damage because the radiator had a leakage. I changed the radiator and heater assembly hose that it was damage, too. To replace a re-build trans. I was told that I need 5K that I don't have it right now. But, sooner of later I have to replace it. I called my dealer and I was told that I'm in my own.because my car has 137K miles. I found out that there are more than a few owners with the same problem.
