The lock actuator on the rear hatch broke and I was unable to close the hatch or lock the vehicle. After dissembling the actuator there was a small plastic pin that broke that prevented the latch from engaging. I then had to pay over $400. 00 to have it replaced for a plastic piece that probably cost less than $1 to manufacture.

The contact stated that he had to utilize the keys to unlock the door which sets off the alarm system. The contact stated that when the alarm would engage, the alarm would not shut off until the engine was started. In addition, the interior unlock button had become inoperable. The vehicle was taken to the dealer for the failure and the dealer advised that the door actuator would need to be replaced on all five doors, including the hatch back at a cost of $400 per door. The vehicle was not repaired. The contact stated that the failure would only recur in hotter temperatures. He called the manufacturer but no assistance was offered.

2004 Infiniti Fx45 - door power lock (actuator) not working correctly. This failure is an intermittent of operation. Sometimes the doors lock ok, other times they don't. In addition, sometimes the doors unlock ok, other times they don't. It is possibly a safety issue. The door lock is most "lazy" and the problem worsens in hot weather. Quick search online reveals that this is vastly common problem in Infiniti/Nissan cars. 1. Having a secure environment is paramount in certain neighborhoods. When locking the doors it's imperative nobody can gain access at will by walking up to the car. If anyone can simply open the door to gain access, carjacking, injury, or even murder is easier. If the doors locked properly this provides a more secure environment for this type of scenario. 2. Nissan knowing there is a security problem with their locking mechanism and not recalling them for safety concern is negligent. In this case there's no obvious indication the door isn't locked unless someone walks up and opens it from the outside. The driver "thinks" the door is locked, when in reality it's an "open door" for carjacking or robbery. This failure is an intermittent of operation. Sometimes the doors lock ok, other times they don't. In addition, sometimes the doors unlock ok, other times they don't. 3. In emergencies it's important to be able to unlock doors quickly. Since 99% of the time we all use the button to lock and unlock doors, using the manual locking lever is unfamiliar. In emergencies every second counts. The locking/unlocking solenoid malfunctioning is clearly a high risk in emergency scenarios. Some people who cannot afford the $1600 to have all the locks replaced (as quoted by dealers) will forgo getting them fixed, putting their family members at risk with the above mishap examples. This shouldn't be, Nissan should recall them.

Front passenger door lock and rear driver's side door lock do not close and / or open when either door lock switch in car is pressed or door lock on remote is pressed. Am told it can be an actuator. Called the dealer to get repaired and told it is not a recall and want to charge hundreds of dollars, yet just from using search engine online there are hundreds of other customers experiencing the same issues on Nissan maximas, altimas, muranos, infinity Fx45, fx35, amongst many other "Nissan" vehicles.

My wife seems to be affected by the same problem all other fx owners on here are affected by. She can not get into her car without the use of her key. It is terrible to pay that much for a car and have to stand in the rain fumbling with your keys. Both driver side doors are affected. I am unaware if temperature is the cause like some others feel. We live in texas where it is always over 85, so I cant do that study. I hope that infinity is going to do something about this.
