What is wrong

On certain vehicles, moisture could enter the driver-side door lock microswitch and cause it to corrode. As a result, the microswitch may fail to automatically engage the parking brake and/or the auto park feature when the door is opened. If this happens, the vehicle could roll away. Note: This problem could also cause the radio and/or interior lights to remain on after exiting the vehicle.

Why it matters

A parked vehicle that rolls away could create the risk of an injury or a crash.

What the dealer will do

To reduce the safety risk, Mercedes-Benz recommends that you should always use the parking brake when you park. Mercedes-Benz will notify owners by mail and advise you to take your vehicle to a dealership to replace the driver-side door lock.

What is wrong

Why it matters

Headlamps that cause glare or confusion for oncoming drivers could increase the risk of a crash.

What the dealer will do

What is wrong

On certain vehicles equipped with the emergency calling (eCall) system, the communications module may temporarily lose power during a crash. If this happens, the wrong vehicle location may be transmitted through the eCall system. This could cause emergency responders to be sent to the wrong location.

Why it matters

If the eCall system sends out the wrong location after a crash, there could be a delay in response from emergency services.

What the dealer will do

Mercedes-Benz will notify owners by mail and send a wireless over-the-air update to each vehicle. If the update cannot be completed successfully, you will be notified to schedule an appointment to have the update performed by a dealer.
