According to the automaker, software problems may cause a failure of the eCall system to communicate the correct location of a vehicle in a crash. Instead, the eCall system will register the location of the vehicle’s last ignition and send emergency responders to the wrong location.

Mercedes opened an internal investigation in October 2019 based on a European report from the Mercedes-Benz eCall center where the automatic eCall system relayed an inaccurate vehicle position. The automaker says it couldn't find any additional complaints and crash tests didn't indicate any issues.

Working with the supplier, Mercedes found how the software design of the communication module affected the relay of location information for the European incident.

In September 2020 different power supply technologies were compared to understand which vehicles in the field might also have eCall location problems.

From October 2020 to January 2021, Mercedes reviewed German crash data which indicated additional similar events where the vehicle position transmitted by the eCall system was incorrect.

Engineers learned the problem can occur if there is a drop of the power supply to the communications module during a crash, caused by the software design of the communication module by the supplier.

Mercedes-Benz also had trouble with its eCall emergency system when a small recall was announced in February 2020.

In Canada, a Mercedes eCall recall includes more than 75,000 vehicles.

Either a Mercedes-Benz dealer or an over-the-air service will update the software of the eCall communication module once the recall begins April 6, 2021.
