Mercedes-Benz vehicles recall: eCall software may fail to report correct crash location

Mercedes-Benz is recalling 2016-2021 vehicles with eCall software that may fail to communicate the correct crash location to emergency services, potentially delaying emergency response.

What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: This is a risk-of-harm product where no injuries have been reported. The eCall emergency call system is safety-critical; failure to communicate correct crash location could result in delayed emergency response and increased risk of injury to vehicle occupants, but the source documents no actual reported illnesses or injuries.

Plain-English summary

Mercedes-Benz USA, LLC is recalling certain 2016 through 2021 model year vehicles for a software defect in the communication module that controls the eCall emergency calling system. The software design may fail to communicate the vehicle's correct location to emergency services in the event of a crash.

If the eCall system fails to transmit the correct location, emergency responders may be dispatched to the wrong location, potentially delaying emergency response and increasing the risk of injury to vehicle occupants.

The recall affects multiple Mercedes-Benz models from model years 2016 through 2021. Affected owners will be notified by Mercedes-Benz. The remedy involves a free software update to the communication module, which can be installed either at a Mercedes-Benz dealership or remotely via over-the-air (OTA) update. The recall remedies began March 12, 2021.

Owners may contact Mercedes-Benz customer service at 1-877-762-8267 (reference number 2021020025) or the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153) for additional information.
