I often get squealing sounds from a door when opening or closing it with the remote or the lock button on the console.

The dealer has replaced door actuators 10 or more times in 4 years.

Does anyone have this problem?
What is the problem with the door actuators? Can anyone explain?
What will happen if the actuator is not replaced? Will the door lock fail?

Hello Tcpgv,
I have no experience of this condition, but if the actuator squeals when in opperation, and the fact that you have gone through 10 actuators in 4 years, would lead me to the conclusion that your door is missaligned.It might be worth checking alignment.
