Some time ago, the power locks stopped locking or unlocking. When it gets hot and the vehicle is in the sun for some time, the doors do not want to open. Some times it could be all the doors or just some. We had to climb over the back seats to unlock the doors because the lift gate is the only one that got unlocked. Some times we need to wait for a while pressing the remote hoping to get lucky and one door will unlock. Not even the key works to open the driver side door. It has got to the point that now we need to leave one door unlocked so that we can enter the car and hope that the alarm will deter any body other than us trying to get in. This has become a serious security problem. Searching the internet, they say that the door actuators are the culprits to this issue, but there is many Nissan/infinity owners having the same problem. All of the actuators going at the same time? …
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? …
Have a 2003 Infiniti FX35, and the electronic locks now do not fully lock or unlock the rear doors. First one door went out now the other. My sense is that a small child or elderly person in the back could be in serious danger if there were an immediate need for them to be evacuated. With only one manual lock for the entire vehicle (on the driver's door) a person would have to go across the car to manually unlock the passenger side rear door in an emergency (in addition to reaching behind the driver's seat for the driver's side rear door). Since I see this as a significant safety issue, I believe NHTSA should investigate and order an appropriate recall. If you peruse various message boards on the web, you will see that this is a rather significant issue associated with many Nissan products (the sister murano is also so afflicted).
Power door lock actuators operate intermittently. There has been several instances having the rear child door lock engaged and we could not open the rear doors from the outside because the actuators failed. Children had to exit out the front by climbing over the front seats. While at a parking garage a large vehicle parked close to the passenger side of our car and could not open doors to re-enter. Again, intermittent operation of power door lock actuators , both front and rear driver side door locks failed. We had to enter the vehicle through the rear tailgate/hatch. Took vehicle in for service and lock were operating at that time and manufacturer recommended replacing the door lock actuators. Still to this day the locks operate intermittently, and now have 115,000 miles.
