The rear latch door lock on my 2004 Infiniti FX35 has suddenly become inoperable. I discovered this after I placed shopping items in the rear compartment and drove. I noticed the rear door was not closed after driving about a mile and had to pull over to attempt to close it. When I tried it would not close and the rear door lock compartment appeared to be stuck and keeping the door from closing. Once I manually manipulated the lock on the bottom of the latch door to open it, I closed the door and the door now will not unlock. After research I discovered this was a Nissan part called the rear door actuator that stopped working. According to my internet research this is a very common and costly problem for Nissan owners and sometimes occurs with multiple passenger doors for some owners. …
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 am a 2004 inifiniti FX35 owner. I had a right front passenger door lock actuator become inoperable, so had it replaced about 3 years ago. And recently, the driver's side door lock actuator failed, replaced it for a cost of over $500. $303 for the part alone and $216 for the labor. I know the same part costs about $35 at an Infiniti service in other countries. I searched on the web to see if anyone else has a same problem as me and was surprised to find that there are a number of people, both Nissan and Infiniti owners, have had door lock actuators all around the car (including the rear hatch) fail on them. I feel that I have been unjustly charged for this part and labor as I have seen the same part get replaced at an overseas Infiniti service myself recently for a cost of $50 with $35 of it being the part price. Why is it almost 10 times more expensive here? …
My daughter drove home from college and attempted to open the driver door. It was locked and would not open from the inside or the outside. If face none of the doors would open from inside or outside. She rolled town the window and climbed out. We took the auto to the dealer and they said that they had seen this before.. I thought it was a factory defect but alas $ 2,600 dollars later we learned that we must pay for the defect. I contacted Infiniti several times and they refused to acknowledge that this was a problem. This could have been a very dangerous situation in case of an accident, etc because you could not exit the auto nor could anyone else open the doors.
My 2004 Infiniti fx 35 door lock actuator for the passenger and rear door hatch will not open unless pressed several times and occurs all the time and I consider it a safety issue in a life or death situation, the dealership will fix the problem but at a cost to me of over 300.00 us dollars which is high price to pay when at this point in time economically is very difficult so I plead with NHTSA to consider it a recall because I am sure that I am not the only person with this problem.
Tl* the contact owns a 2004 Infiniti FX35. The contact stated that the rear door hatch motor malfunctioned and the hatch would not close automatically.

Keyless entry and internal door locking actuators not working properly. Automatic steering wheel and seat positioning system does not work (intermittent). Doors fail to lock when actuated. Also when locked and keyless entry is activated various doors /or rear hatch will fail to unlock. Also when exiting the vehicle passenger door (front) fails to lock or unlock either remotely of by pushing the door locking button.
The rear hatch mechanism on my Infiniti FX35 failed and made the vehicle completely accessible to anyone who walked by. The dealer is charging $450 to repair it, but when I check the internet, it appears to be a common problem. This is suspicious and should likely be a recall due to the safety of the vehicle being compromised. Items May fall out of the cargo area with this problem and cause accidents on the road.
2004 Infiniti FX35 automatic door lock actuators failing to unlock or lock the doors. This started happening a few weeks ago with the rear cargo door failing to unlock. Now all of the doors fail to lock and unlock intermittently. This is a safety issue. I have not taken any action yet but if this keeps up I will be forced to spend nearly $2500 to have the actuators replaced.
My 2004 infinity fx 35 door actuator went out all four of them,this car is keyless entry. I have a child and it seem dangerous to use this car for our family anymore. Sometime I'm afraid to lock it and worried if a fire or emergency happened ,I couldn't get out of the car. Or I couldn't open the door to get the child out. This is very bad and must be corrected by infinity.
