2005 Infiniti FX35 Electrical system Problems

“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. …”

“The door lock actuators are failing in a lazy manner in my 2005 inifiniti FX35. It started with the passenger side lock and now includes the rear hatch. When unlocking or locking the doors either with the fob or with the switch on the driver side door, these doors intermittently will not lock or unlock. The frequency at which it does not work is increasing with time. The danger is that I have to manually check if the door are locked. Even when they are locking I can never be sure if they are locked because I never know when they will stop working again. …”

“Started in 2008 for first time, but was intermittent. By summer of 2011 none of the doors/rear hatch unlock or lock automatically. Neither using the fob clicker, or pressing any of the interior lock/unlock buttons activates the locks. Since there is only one key hole, for entire vehicle, on driver's side, I am unable to access rear hatch area, and this is where I keep my dog as well as caged pet birds when transporting. To unlock hatch, I have to use key to unlock driver's side door, then reach my arm back to the rear passenger door and unlock manually. …”

“I own an Infiniti fx 35, 2005. My front passenger door and hatch door locks have failed ( the actuators). I called my local dealership, expressed my concern as it is a safety issue, esp since there is no key hole entry for either the passenger side or the hatch door. They did not feel this is an issue that Infiniti should be responsible for. I brought my car in to the local dealership to have examined, and fixed (because again, this is a safety issue)....they told me that all my locks are failing (actuators) and it will cost $1700.00 to fix. …”

“I own a 2005 Infiniti FX35. Within this last year, I have had problem with all 4 locking mechanisms including the rear hatch of my vehicle. This first began with the rt rear passenger side and has now affected the remainder of the door locks. The failure is that when the door lock button fails to either lock and or unlock any of the doors. This is a constant problem. When the door lock button is depressed there is a locking sound heard, but the action doesn't take place. When disarming the alarm with the key fob, and entering my vehicle I find it does not open my driver door. …”
