Defect
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.
Safety Risk
If the emergency call system does not work in an emergency situation, there could be a delay in response from emergency services.
Remedy
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.
