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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2005-2007 Pathfinder appears to have a widespread defect where coolant leaks into the transmission, causing transmission failure around 90,000 miles. Repair costs are typically upwards of $3,500.

According to the New York Times & a class action lawsuit, the defect actually extends through 2010 model year. More info here.

Driving home after the car has been warmed up for quite some time it started jerking shuttering violently and whining extremely loud upon acceleration it continued to worsen we checked radiator and transmission fluids there was atf fluid in the radiator and in the reservoir of radiator fluid it was thick frothy and almost a tannish color that like of strawberry milk. We were only about a half a block from home when this occurred and it frightened our children in the backseat thankful we were not on the interstate the shuttering was extremely bad

The transmission fluid was contaminated because there was a hole in the radiator. The radiator and transmission need to be replaced. I have 112,781 miles. This is a known problem with Nissan Pathfinders. Nissan extended coverage up to 100,000 miles. The radiator should have been recalled and all owners should have been notified.

Nissan has an issue with the radiator leaking into the transmission, causing the car to shutter while driving.the transmission will go eventually!! Nissan is totally aware of the issue, and if you have an extended warranty for the powertrain it is not covered, because they do not consider the radiator, part of the powertrain!!I it will just be a matter of time before it leaves me sitting along the road! I hope I can get off the road and not cause an accident! Nissan really need to fix this!! thankfully no incident has happened, but I thought this should be told!

On highway driving home from work when transmission suddenly failed, causing a dangerous situation for myself and fellow drivers. It was a very harrowing experience, to say the least. It now sits with the mechanic, who informs me that the dreaded engine coolant/transmission contamination issue has occurred...unfortunately, my vehicle is over 10 years old and over 145,000 miles, so the recall notice does not apply...I now have to come up with $5,000 for can Nissan ignore this issue and neglect their customers?

On the second day of owning my Pathfinder I noticed a vibration when I was driving around 40 mph. I took it into the shop less than a week later to have the transmission flushed and to disconnect the radiator from the transmission (did this due to research we found on the internet). The mechanic did see that my transmission fluid was cloudy meaning the coolant was leaking into the transmission. My vehicle was working great for about two weeks until one day I noticed a jerky feeling when driving my vehicle on a city street. That jerky feeling shortly turned into the vehicle shaking when shifting, which turned into not shifting at all after stopping at a red light. My vehicle would barely accelerate, mostly engine revving, luckily I was on a hill where I could coast to the side of the road. This occurred within 5-10 minutes, very quick, little warning. This could have been a very dangerous situation and could have ended worse than it did!!!

The contact owns a 2006 Nissan Pathfinder. While driving various speeds, the transmission began to slip gears without warning. The intermittent failure recurred and became progressively worse. The vehicle was taken to an independent mechanic who stated that the radiator coolant leaked into the transmission fluid, which caused internal damage to the transmission. The mechanic stated that the transmission would need to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 143,000.

While driving on interstate 25 in South denver, my Pathfinder began to sputter and stall. The engine started to overheat as I pulled into a service station about two miles away. I had it towed to christian brothers auto in parker Colorado. A radiator part blew, the engine overheated and was destroyed. The steam from the plastic radiator part also damaged the main computer. It was close to $10,000 for all repairs related to the radiator part failure. Approximately 8,000 miles later, my daughter and I were driving on I-70 near the vail, Colorado exit, and the Pathfinder started to jerk violently on the highway going 65mph. I was able to pull over to the side of the road. Scary experience for us both. This happened today, 03/24/2016. Smoke was coming from under the car. I had it towed to avon auto in avon Colorado. They said the transmission is damaged, but they did not have time to look into it further. Please call or email me with further questions. 303-726-6211 or

The contact owns a 2006 Nissan Pathfinder. The contact stated that the vehicle was constantly remaining stuck in first gear and in reverse. The vehicle was towed to the residence and then taken to a dealer for diagnosis. The vehicle was also inspected and diagnosed by more than one independent mechanic. The mechanics all informed that there was a failure in the transmission due to the radiator having an internal premature fracture, which caused the coolant to leak into the transmission. The vehicle was taken to the dealer, who diagnosed that the radiator and the transmission needed to be replaced. The manufacturer was notified of the failure. The approximate failure mileage was 142,320.

  • 109,112 miles
Vehicle jerks and stalls and even cuts off during driving. I was driving on the interstate and went to change lanes and the engine just shut off. I tried to pull to the side of the road quickly but I had no engine power. I coasted to the shoulder of the road and called my husband to pick me up. I had the vehicle towed to my mechanic and he advised us that the automatic transmission fluid had contaminated the anti-freeze and vice versa and that I'd need a new transmission and radiator installed for $5500. He also added that Nissan had just lost a class action lawsuit to repair the vehicles affected but the catch is that your vehicle can not have over 100,000 miles on it. From my research in the forums, the issue does not arise until the vehicle mileage exceeds 100,000, so we're basically screwed for repairs on our Nissan with 100,001 miles or more. I'm double screwed as I have 2 2006 Nissan's. my other vehicle is currently inoperable due to atf contamination.
