Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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.”
NHTSA complaint #10470769, filed 2012-08, 96,000 miles“The door lock on the passenger front door no longer works via the power door lock switch or key fob. It must locked/unlocked manually. The mechanic reported that the lock actuator needed to be replaced.”

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.”

NHTSA complaint #10296648, filed 2009-12, 35,000 miles“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. …”
