Nissan note door lock buzzing.
Have owned the car for 3 months and it has not changed at all in this time.
In some cars a door lock actuator becomes noisy and produces a squeaking or buzzing noise when the power door locks are locked or unlocked.
I can find nothing stated in the owners manual that this noise should occur.
Is this an intentional audible confirmation of locking or is it a potential problem.
Usually a buzzing noise when locking the doors is a sign that either the door lock actuator is failing or it is bound up and it cant move.

If the electric motor or the mechanism inside the door lock actuator wears out the door lock may lock or unlock slowly or work sometimes but not all the time.
