This thread is somewhat older already, but wanted to voice-in and add that there is an issue with the FX transfer case! I drive a lot for work, and bought the FX35 because it's a great car and an extremely comfortable ride. In March 2012 I started to have problems as described above in the TSB. Brought it to the dealer and they did conclude the transfer case was blown and needed replacement. The car was at 83K at that moment, 3K over the 80,000 power train warranty... I wasn't too happy about this of course, but contributed it to a case of bad luck and moved on. The moving on didn't last too long... 37,000 miles later I started experiencing the same issues and guess what: the replacement transfer case is broken too.
I'm now on my 3rd transfer case for a car that's not even 5 years old and at 120K miles. The dealership felt really bad and offered to replace the 2nd transfer case for 50% off, which I think is a nice gesture from them. I was hoping (counting on...) Infiniti consumer affairs to pitch in the second 50% but unfortunately they didn't come through. After escalating my case, they concluded that it's acceptable to replace a transfer case twice I guess. I'll escalate my case (11523919) to the BBB, but the reason I wanted to post on this forum:
1) beware that the transfer case on an 2009 Infiniti FX is a weak spot!
2) does anyone has any ideas what causes this issue? I don't want to go to the dealership in about a year to have my 4th transfer case mounted. If there's anything I need to do different, or if there's anything I need to pay attention to during maintenance I would appreciate the advise.
