What's wrong?
The communication module in the 2021 Mercedes-Maybach S 580 and S 500 is the software-controlled part that connects the emergency call system to outside responders. In a crash, or when the SOS button is pressed, that system is supposed to place the call and send the vehicle location so help can find the vehicle.
On affected vehicles, a control unit configuration or software error leaves the communication module outside current production specifications. That means the emergency call system can fail to place an automatic crash call or a manual SOS call. It can also fail to provide the vehicle location as intended, which defeats the purpose of the system after a collision or other emergency.
The warning sign is a message in the cabin display. Owners can see "SOS not ready" in the head unit display or "SOS inoperative" in the instrument cluster before the emergency call system fails.
Who's affected?
Scope includes Mercedes-Maybach and Mercedes-Benz versions of the S 580, plus the Mercedes-Benz S 500, tied to the same software COM module.

What's the safety risk?
A disabled emergency call system can stop an occupant from contacting emergency services or sending the vehicle location during an emergency. That delay increases the risk of injury. If the display shows "SOS not ready" or "SOS inoperative," schedule the software update soon. Repair is free at any franchised Mercedes-Maybach dealer.
What should I do?
- Check your VIN to confirm your 2021 Mercedes-Maybach S 580 or S 500 is included in this recall.
- Contact a franchised Mercedes-Maybach dealer to schedule the free communication-module software update that restores emergency call and vehicle-location reporting.
- Bring the recall notice if Mercedes-Maybach mailed one. If not, reference recall number 24V807 when you call.
- Keep a charged phone with you until the software update is complete, since the emergency call system is the affected system.
- Call Mercedes-Maybach customer service at 1-800-367-6372 with questions about the repair.
What happens at the repair
At the dealer, a Mercedes-Maybach technician updates the communication module software for the emergency call system. The software update and labor are free under the recall. This repair addresses the system that places automatic or manual emergency calls and sends vehicle location information. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain covered under that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
