The Door Locks May Cycle Rapidly on Mercedes-Benz ML350

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.
FRONT PASSANGER SIDE DOOR LOCK IN NOT LOCKING EIGHTER ELECTRICALLY OR MANUALLY. MAKES MACHINE GUN LIKE NOISE WHEN SWITH ON TO LOCK. THIS CAR IS PIECE OF JUNK FOR THE MONEY WE SPENDS. DO NOT BY ANY MERCEDES. IT IS NOT WORTH
