2017-2022 Mercedes-Benz Classes Recall 22V365: eCall Fault

Recall 22V365 covers 242,722 2017-2022 Mercedes-Benz vehicles with eCall software failure. The OTA update or dealer repair is free at any franchised Mercedes-Benz dealer.

What's wrong?

The communication module in these 2017-2022 Mercedes-Benz vehicles is the car's link to the mobile network. Its SIM card software lets connected services communicate outside the vehicle, including the emergency call system, also called eCall. When that link is working, the eCall system has the network access it needs to send an emergency call after a qualifying event.

On included vehicles, an interaction between the SIM card security mechanism and the affected SIM profile can disable the SIM card software. Once that happens, the communication module loses its mobile network connection. The vehicle can still run, but the eCall system is disabled because it no longer has the connection it needs.

There is no warning sign before failure. Mercedes-Benz says the driver will not receive a warning because of the way this failure happens, so the VIN check decides whether this software issue applies to a specific vehicle.

Who's affected?

Spans the 2017-2022 model years across Mercedes-Benz and Mercedes-Maybach vehicles, with communication-module software grouped under auto crash notification and electrical system software.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific vehicle is included.

What's the safety risk?

A disabled eCall system prevents an occupant from reaching the emergency services call center during an emergency. That delay increases the risk of injury because responders are not contacted through the vehicle. There is no warning sign before this failure, so confirm coverage by VIN and ask the dealer how the software update will be handled. Repair will be free at any franchised Mercedes-Benz dealer once available.

What should I do?

1. Check your VIN to confirm whether your 2017-2022 Mercedes-Benz model is included in this recall.
2. Watch for Mercedes-Benz owner instructions for the free communication module software update if your VIN is included.
3. Contact a franchised Mercedes-Benz dealer and ask whether your vehicle needs the OTA update or an in-dealer software update for the eCall communication module.
4. Reference recall number 22V365 when you call, and ask the dealer to confirm that the update fixes the SIM card software error that can disable emergency calling.
5. Bring the owner letter if Mercedes-Benz sent one, or bring your VIN and recall number 22V365 to the dealer.

What happens at the repair

Because the remedy status is not listed as open, treat the final repair as pending until Mercedes-Benz confirms it for your VIN. Once available, the communication module software update will be free, either through an OTA update or at a Mercedes-Benz dealer. At the dealer, a Mercedes-Benz technician updates the communication module software so the SIM card software can keep the mobile network connection needed for eCall. If you already paid for a related repair before the recall notice, Mercedes-Benz's standard reimbursement plan covers eligible documented expenses. Contact MBUSA customer service at 1-800-367-6372 for claim instructions.
