The short answer
NHTSA received Mercedes-Benz USA, LLC’s report on Feb 12, 2021. Copied from NHTSA on Oct 28, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
A disabled eCall system would prevent a vehicle occupant from contacting emergency services through the call center in an emergency, potentially delaying emergency responders and increasing the risk of injury.
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2017-2019 C300, E300, 2018-2020 CLA250, 2020 CLS450, AMG E53, AMG GT53, GLE450, 2018 AMG E63, AMG GTA, 2017-2020 GLA250, GLC300, 2019 GLC350, AMG GLC43, 2017-2018 GLE350, 2019 AMG GLC 43, GLC350, GLE400, 2017 GLS450, S550, C300 Cabrio, and 2018-2019 S560 vehicles.

The communication module might have been inadvertently deactivated during a service visit, which could have disabled the Emergency Call (eCall) function.
