A number of 2022 Mercedes-Benz EQS and S-Class models are being recalled in the United States due to an issue related to their eCall functions.
The notice issued by the National Highway Traffic Safety Administration (NHTSA) lists that the eCall function might not be available or restricted at vehicle start-up, meaning customers may not be able to get in touch with emergency services. This could be particularly problematic in the event of an accident where emergency responders may not be directed to the location of the vehicle.
Mercedes-Benz has said that a software bug in the control unit means the communication module might not meet operational requirements. Owners of impacted vehicles may receive a warning message in the display or may not have access to the Mercedes me connect services.

The German car manufacturer first started to investigate the issue in May 2021 and after determining that a software problem was to blame, new communication module software was introduced at all relevant production plants from the end of 2021. However, a number of vehicles were produced before this fix was made.
Involved in the recall is a single 2022 Mercedes-Benz EQS450, no less than 1,161 Mercedes-Benz S500 models built between February 15, 2021 and December 4, 2021, and 77 Mercedes-Benz S580 models manufactured between February 15, 2021 and December 4, 2021.
Vehicles equipped with the Mercedes me subscription service will receive an over-the-air update to fix the problem. Cars without a Mercedes me subscription will need to be taken to a Mercedes-Benz dealership where the new software will be installed.
