My door locks are faulty

Hello Paul, my old 1999 Mercedes ML 320 door locks keep opening and closing by themselves when I start driving. What could be the cause and fix? Sandra

Hello Sandra, one or more of your car door locks is damaged. Your Mercedes ML like some other cars, has a security feature which when activated can automatically centrally lock all doors when you drive off.

In the event that one or more door locks are faulty, the feature will keep cycling and trying to lock the doors at certain speeds such as 5km per hour, after every stop.

Door locks can fail due to ageing, dust or water intrusion. Replacing the door locks are the ideal permanent solution.
