Problem Description and Possible Solution
Electrical switches in the door latches can fail, causing the door locks to rapidly actuate up and down multiple times when the locks are activated by either the keyless remote or door lock switch. The affected door latch should be replaced to correct this concern.

On my 2003 ML350 the passenger front door fires several times and then fails to lock. You can't even lock the door manually which is a safety concern. I felt it was unsafe to let my family ride in this car when the door couldn't be locked and we could not leave the car unattended which was a unacceptable situation when you are out of town over the holidays. We couldn't get it fixed because shops were closed and we couldn't leave Christmas presents in car because we were afraid someone would steal them.
My both front doors are not be able to lock up.
updated, just picked my car up today.
it cost me $1645 to repair both front door.
really expensive, hope it is not going to happen again!
the door to the driver dose not look when i look the car, but the security we activate, but only the driver door nub will not look.
