One problem related to door has been reported for the 2004 Infiniti FX35. The most recently reported issues are listed below.
3 doors on my 2004 Fx35 will not open from inside or outside-this is a safety issue. First week in sept I tried to open back door to retrieve my books, etc and the door would not open. I leaned in from driver side and noticed door was unlocked so I tried to open from the inside-it would not open,. My auto has only 46,000 miles on it. I took to dealer and he said he had never seen this happen before. He kept the car for 3 days and said it took them all day to open the 2 back doors. He said all for on my acculatos(something like that) failed and they replaced them at charge or over $ 2000. 00. This is a serious flaw in the auto if the doors can not be opened from the inside or outside. What if I had been in an accident and the doors could not be opened? I firmly believe this is a problem that should be addressed by the mfg and I should not have had to pay over $ 2000. 00 for something that I did not cause. Rarely as anyone ever rode in my back seats as usually I am a lone rider or driver in the Infiniti.
