Mercedes-Benz recalls more 2021 S450 models over SOS function failure

The 2021 Mercedes-Benz S450 has been recalled for a fourth time, as the German manufacturer's SOS system yet again causes dramas.

Just 178 units have been placed under recall this time, down on the 257 affected by a similar recall in October last year, although the problem with the SOS emergency call function in Mercedes-Benz's passenger vehicles persists, adding to the nearly 40,000 vehicles hampered between 2018 and 2020.

As with previous recalls related to the system, a software issue with the eCall communication module means it may become deactivated and unable to connect to certain networks, preventing occupants to contact emergency services in the event of a crash.
