Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I was driving towards reno, nv and every time there is an uphill roadway the engine would rev up and the transmission shifts to another gear, I would feel a thumping sound and on every 3 to 6 miles of driving the vehicle would feel like it is running on an unpaved road. I took the vehicle to the dealership and that is when they informed me that my transmission fluid and engine coolant are mixing. Not to mention that my fsr is no longer functioning properly. It turned out that the fsr (fuel sensor relay) is not on the recall list unless it is a 2006 and up. I don't mind the fsr, because I can work on this but the coolant and tranny fluid mixture should be a recall since a lot of people are experiencing this issue.

Transmission went out on vehicle while it was in motion causing vehicle to stall and difficulty picking up speed to merge into 65mph highway traffic almost resulting in a collision. When vehicle was towed to transmission shop, they informed me that these Nissan Pathfinders are known for having bad radiators causing water to enter transmissions making the transmission to suddenly go out...I then had it towed to a second shop and they confirmed radiator went bad. Radiator was replaced but transmission is completely out due to the radiator.

It appears the radiator failed leaking coolant into the transmission. When I asked the mechanic about it he said that now your transmission will fail soon. I have been reading that this is very common and has happened alot with this year and model which I believe to be totally not acceptable.

While backing out of a parking space my check engine light came on and it felt like my transmission was slipping. I had the vehicle towed to the Nissan dealer. They told me the radiator failed and the radiator fluid seeped into the transmission fluid causing everything to fail. 80, 000 miles is the warranty. I am just over that. They are offering me a $2500 co pay but I feel they should take care of this problem. There should be a recall on the radiator to prevent this problem.

I was driving on a highway back from getting groceries in a town 45 miles from me. All of a sudden the car started revving. I took it off of cruise control and tried pressing on the gas. Nothing happened. I pulled off to the side of the road and called a tow truck. After several hours sitting on the side of the road in the dark and by myself, I got it towed back to my town, 35 miles away. I found out that the transmission had gone out. I took it to a transmission shop and they told me that it was the cooling system had leaked into my transmission and fired the tcm. It will cost me $4600 to fix it. I found out that there is a recall on this problem after the fact of it happening and now they refuse to fix their mistake. They will cover up to 80000 miles for the recall and up to 100000 miles with a deductible of $2500. And nothing after 100000. Why did they not inform us of this problem" does anyone have a law suit going on this"

My wife observed issue with gas or brakes for last couple months. I thought it was brakes and I had just bleed and replaced fluid which helped. On 6/20/13 I made left turn on my home street and transmission did not respond. I was stuck in middle of road and luckily no cars were approaching. At first I thought car stalled and tried to restart but realized the engine was still running. At that moment I knew what it was (failed transmission from cross contamination). I drove directly to reliable Nissan in albuquerque where they verified the bad news. This really proves this is a manufacturing defect. My car has all proper maintenance and only has 54600 miles. I am the original owner. The vehicle looks brand new. I had just talked to both service managers from both the local dealers about my fears about this possibly happening. Even had them check and they said the radiator was ok. I am only 50 days past my 8 years and with only 54600 miles Nissan refuses to provide any good will. I am still stuck paying 2500 dollars. Nissan keeps insisting this is not a safety issue. Loosing propulsion is a safety issue. Even in driving school I was trained that power, can avoid a possible disaster just as well as brakes. This is fact. Too many close calls reported on this issue and its sad that our government only acts when cars explode and people die. I have noticed that this issue is increasing exponentially putting the risk of death and injury a more probable outcome. From last February almost 29 percent more cases reported in just 4 months. I worked with my dealers trying to avoid this. Did all the trans oil changes, radiator flushes and asked if I could do anything to avoid this disaster and also had them inspect my radiator just a few months back. And yet, my brand new looking, meticulously maintained Pathfinder needs a new transmission and radiator.

I just bought this car, and had a problem with transmission to begin with, following with the fuel level sensor (just started), I had to replace the transmission, radiator, now I have to replace the fuel sensor, and 2 days ago the plastic heater receiver that is located in firewall of car had melted, and all anti-freeze had gone and the motor got overheated (why plastic made", instead of brass??"), so the dealer said that I had to replace the whole piece ($250) plus labor, it is incredible how this car company called Nissan is loosing their prestige since started to assembly in us, it is just making more money out of the people with all these crappy parts they are using. We need the federal government to be involved and give us back the money spent on these manufacturing defects as soon as possible.

I brought our Pathfinder in to our mechanic for an oil change and inspection. He said that the radiator is going bad. Specifically the coolant that is attached to the transmission. He said that we should not drive the vehicle, as it could blow the transmission. We are lucky that he did such a thorough inspection, as we had no warning signs. I googled the problem and found your website, and that this has been an ongoing problem with Nissan. Our mechanic said he recently had to replace two radiators, one on a 2009 Nissan Pathfinder and another on a Nissan (truck)...I can't remember the model and year.

The check engine light came on in the vehicle the night before. Vehicle was taken to the Nissan service dealership the next day-June 5, 2013-for a diagnosis. Was told the coolant had leaked into the transmission and ruined it. Both the radiator and the transmission will need to be replaced. Was told by the mechanic that Nissan will not pay for any part of the repairs due to being over 100,000 miles. The odometer has 103,000 miles, only 3,000 miles over the limit. This is manufacturer's defect and should be repaired by Nissan, free of charge. After further investigation, discovered that thousands of owners 2005-2010 Pathfinders, X-terras, frontiers and armadas have experienced the same exact issue. The cost for my repair is $6300! Nissan needs to be investigated and the total repair costs refunded to the owners! this is an enormous hardship for this family and all who have experienced this fiasco!

The 2005 Nissan Pathfinder's transmission started to slip and engine speed would dip and vehicle would feel as though it was attempting to shift into a non existent gear at speed. Several weeks after this started to happen a notification was received in the mail pertaining to the coolant leaking into the transmission oil. After having replacing the radiator and flushing the transmission and replacing transmission oil, the transmission is continuing to slip. Awaiting word from Nissan North America to replace or fix this known issue.

The contact owns a 2005 Nissan Pathfinder. The contact stated that while driving approximately 60 mph, the check engine warning indicator illuminated on the instrument panel continuously. The vehicle was taken to an authorized dealer for diagnosis. The technician stated that there was a combination of both the transmission fluid and coolant leaking together, which could cause damage to the transmission. The manufacturer offered an extended warranty associated with a manufacturer's voluntary recall related to the transmission. The vehicle was ineligible due to the excessive mileage. The manufacturer was made aware of the problem. The approximate failure mileage was 119,072....updated 07-10-13

I felt a grinding nose while shifted and I stop and took the car to a dealer Nissan and the find out a problem from transmission/ radiator. There was a recall for a faulty radiator who leaks into the transmission that cause the problem and I should pay for the repair on my own. I find out that Nissan knows that problem never sent me a recall for that and I bought the car new I serviced it and all the maintenance at a dealership no word I should change the radiator. The same thing happens to me with my 2002 Altima.

I have only had this vehicle for a year. I noticed the transmission started sputtering when I got to about 40 or 50 mph. I had it taken in to see what the problem was and they told me the radiator failed and leaked into the transmission and both had to be replaced. Luckily I was not on the road with my children in the car when this thing decided to fail.
