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.

Radiator recall for trans lines leaking into radiator contaminating coolant. And now the timing chain tensioner is causing a loud knock in the engine from the timing chain.

Enjoying our Pathfinder one afternoon and went to pass a car and it would not kick inot passing gear. When we stopped I could smell that it was hot, but could not find a leak. After letting it cool, I checked the coolant level and found that grey froth in the radiator. A quick check on the internet lead me to me worst fear. I am still in the process of flushing radiator and getting quotes. Local aamco guy said that transmission is doomed, and they see a lot of these. $4,000 - 4500 to rebuild. So much money for such an easy repair had I known before the radiator gave up. No more Nissan for this family!

I was told by the dealership there was a bad timing chain - called Nissan and they said they would not financially assist with the repair. There appears to be a civil lawsuit regarding this issue.

"takata recall" out of the clear blue I was driving my 2007 Pathfinder and the airbag light came on, I took it to the dealership immediately that day and it passed per service manager louis castillo at baker jackson Nissan in houston Texas, 2 days later the light came back on and once again I went to the dealer ship and was told that the sensors and other parts needed to be replaced the cost is $1500. I called Nissan Corp and they are refusing to taking responsibility even though they stated all 2007 Pathfinders in other states would be given a 10 year warranty. My truck was also affected with the radiator flulid mixing with the transmission fluid, during the years of 2010-2012 I constantly took my truck to baker jackson Nissan and the service manager then larry just topped off my truck himself and never made a record of it. He kept assuring me that he was saving me money. My transmission failed but because of the mileage in 2012 Nissan was able to deny fixing my transmission via the class action lawsuit. I ended up spending $4800 for a new transmission. In 2010 Nissan convinced me to replace my train for $1600, I never knew it was a recall until today. Another caveat to this mess is that baker jackson changed their computer system and has no record of me replacing my train. I have a bank statement to prove it if necessary.

Transmission cooler inside the radiator cracked and got coolant in the transmission, causing the transmission to die. We went to turn the car on and it wouldn't start, from there we towed it to a mechanic who told us what had happened.

At first, the car wouldn't start occasionally. I replaced the battery and fuses. This helped temporarily. Now, the car won't start unless I place a new ECU fuse each time I attempt to start it. Changing the fuse will start the car, but it lacks power and is quick to stall out. When I took it to the mechanic, he discovered coolant in my transmission. After reading information from several websites, I realized this is an ongoing issue with this make/model of car.

  • 118,000 miles
The transmission on my 2007 Nissan Pathfinder started slipping so I had it looked at and found out the coolant leaked into the transmission. I have 118,000 miles on it and unfortunately it looks like I am out of luck. I an very disappointed in Nissan since they know the failure does not occur until about 90,000 miles.
