COMMUNICATION

Reported to NHTSA: February 12, 2021

Defect Description

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. On June 18, 2021, an additional 9 vehicles were added, including certain 2021 GLA250, GLC300, 2018 S450, E400, and 2017 CLA250 vehicles. The communication module might have been inadvertently deactivated during a service visit, which could have disabled the Emergency Call (eCall) function.

Safety Consequence

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.

Remedy

MBUSA will notify owners, and dealers will inspect the communication module and activate it, if necessary, free of charge. The recall began March 31, 2021. Letters for the owners of the 9 additional vehicles were mailed July 9, 2021. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2021030005.
