Problem Description and Possible Solution

If the power door locks are buzzing or are intermittently noisy, a new door latch assembly may solve this. The door lock actuators are integrated into the latch assemblies.

For the past couple of weeks I've noticed a "clicking" sound when opening my door after the lock was engaged. Today, the lock on the driver's side door is making a "buzzing" sound. How do I fix this?
Power locks randomly unlock and unlock on own while in motion or when vehicle is turned off and parked.
Left rear door lock now has a really loud buzzing/grinding sound when the doors lock that really scares the s#it out of me every time the doors autolock when I start driving and hit a certain speed, even if I already locked it to hopefully avoid that sound...
When locking and unlocking the doors there is a buzzing sound and the passenger rear door will not look or unlock.
Power door locks in the front of the vehicle (passenger and driver sides) started making a humming type of noise and short thereafter, stopped powering up and down both front door locks.
The passenger front was 1st
Power lack will not open or close have to do it manually
Next
Left side back.
Then
Rear hatch stopped opening at all!!
left rear passenger door intermittently will not unlock. Issue not resolved, because it never does it when I take to dealer to repair. Frustrating. Hub has even fashioned a long piece of wood to pull up lock from other rear door side, so I don't have to crawl across back seat to get unlocked. (bad knees)
