What Happened
The eCall system in your vehicle relies on software that helps emergency responders find you after a crash. Unfortunately, the software in certain 2016-2021 Mercedes-Benz vehicles might not send the correct location to emergency services.
Risk if Unfixed
If the eCall system fails, emergency responders could be sent to the wrong location after a crash, which could slow down the time it takes for them to reach you and potentially put you at greater risk of injury.
Free Fix
Your Mercedes-Benz dealer will update the software in your vehicle's communication module, free of charge. This update will ensure that emergency responders get the correct location in case of an emergency.
