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.

Transport Canada lists: C 2022

What is wrong

On certain vehicles, water could leak into the trunk causing the signal acquisition and actuation module (SAM) to short circuit. If this happens, the tail lamps may not work, the rearview camera may not work, and/or the rear seat backrests could fold on their own.

Why it matters

A short circuit could create the risk of a fire. Tail lamps that don't work could make a vehicle less visible, and cause a following driver not to recognize that the vehicle is braking or intends to turn. A rearview camera image that does not display correctly could reduce a driver's ability to see behind the vehicle while backing up. These issues could increase the risk of a crash. Additionally, a backrest that folds on its own could increase the risk of injury.

What the dealer will do

Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealership to install a cover over the signal acquisition and actuation module (SAM).

What is wrong

On certain vehicles equipped with the emergency calling (eCall) system, there may be a software problem with the communications module. As a result, the emergency call feature may not work properly when there is a crash or when the SOS button is pressed.

Why it matters

What the dealer will do

Mercedes-Benz will notify owners by mail and send a wireless over-the-air software 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.
