“I have a 2003 infinity FX35, for some time I have been having trouble with all the door actuators they sometime work and some not, now they don't work at all. It started with the drivers door and like 2 months later the rest of the doors including the trunk. I had it check with an electromechanical and he told me is the door actuators that I have to replace all of them. I have been reading that this happens to all infinity FX35 models and some others. I really think this is a very serious safety issue and something most be done about it.... …”
NHTSA complaint #10444765, filed 2012-01, 98,000 miles“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.

NHTSA complaint #10493569, filed 2013-01, 97,878 miles“All doors will not lock or unlock. Nissan / Infiniti has known about this issue since 2005 there are hundreds if not thousands of vehicles affected. I'm tired of going round and round with them to fix this safety issue.”
NHTSA complaint #10706282, filed 2015-04, 68,000 miles“Front door locks intermittently work. Some times they will not unlock with the key fob and must use a key. Recently they have been locking by themselves as if the actuator fails.”
NHTSA complaint #10611141, filed 2014-07, 107,000 miles“All four door locks as well as the hatch lock ceased to work properly (I.e. Would not lock or unlock when the automatic lock button was pushed.) told that it was an actuator problem, and that all would need to be replaced (at great expense). This is an obvious safety issue. First, with children in the car, doors could not be locked or unlocked quickly in the case of an emergency. Also, when driving alone, security of the car was likewise compromised. …”
