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 Xterra 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.

The same defect exists in the Pathfinder & Frontier as well. And according to the New York Times & a class action lawsuit, the defect actually extends through 2010 model year. More info here.

I was driving my car and it shifted into 4 wheel drive at a red light with no prompting. The car then was immediately pulled over and turned off. The car would not start following it being turned off. It was then towed to a mechanic shop where they discovered that the radiator had leaked fluid into the transmission, causing the coolant to mix with the transmission fluid and completely disabling the car.

Nissan unsafe failure parts transmission and radiators hi my name is [xxx] my story begins as a happy one, but soon turns out to be my worst nightmare back in November 2007. I bought my first car a 2007 Nissan Xterra from avondale Nissan brand new which is now paid off. It was a very nice vehicle, had really small issues with normal wear and tear and normal maintenance which I kept up on myself. Right now IM attending asu for premed and I need my vehicle to get to school. The issue started when I was driving on the highway, all of sudden I heard a noise and the back end shuddered as if I was driving over rumble strips. I took it in on my next oil change to discover that the transmission fluid had leaked into the coolant, then I had the radiator replaced, then a couple months later my engine light came on and the same issue which I was previously having with the my transmission fluid leaking into the coolant began again. In addition to that incident, I was told from numerous dealerships including Nissan that the radiator was damaged and now the transmission was also damage. I then started googling the problem and to my surprise to find out that so many other Nissan owners were experiencing the same problem. This horrified me when I went to the dealership where I purchased it new in 2007. The service advisor in the service department told me this is a terrible problem because Nissan is aware of this horrible design flaw on Nissan's part and theyre not doing anything to help their customers, he said that Nissan is not going to do a recall at all its just a defect. He also stated that to fix the transmission and get another radiator would cost $500 for the radiator and $5155 for transmission not including tax or labor. I will never in my life ever buy a Nissan again nor would I recommend someone to purchase it! IM not getting any answers from them they are fully aware of this unsafe defect.
