Electrical switches in door latches may fail on Mercedes-Benz ML500

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. A new door latch will need to be installed.

2 door locks failed recently...expensive fix...like always.
Drivers door won't lock unless I'm driving and lock it manually. Then when I stop and open the door the door unlocks and won't lock again. Very frustrating !!!

This has been a nightmare.....replaced over time 4 door actuator/switches. Independent mechanic replaced each one for a cost of about $450 each
