These vehicles are a terrific example of German engineering and dependability and are still very popular with drivers in the European import market. Although drivers of these sport utilities widely report no problems with their vehicles, some owners have experienced technological issues with their vehicles, specifically the automatic door locks.
In most cases, Mercedes-Benz M Class SUV drivers report failure of the automatic door locks in which the remote locks will function on all but the driver’s side door. This means that in order to unlock the vehicle, someone must enter from one of the other doors and manual lift the latch on the driver’s side to allow the driver entry. Once inside, the driver’s side buttons on the inside of the door also will not function. Usually, these individuals also report that when they actuate the button, no clicking or motor sounds can be heard.
