2022-2025 Mercedes-Benz Eqe/Eqs/S Recall 25V366: AVAS Sound

Recall 25V366 covers 94 select 2022-2025 Mercedes-Benz electric and plug-in vehicles for incorrect reverse pedestrian-warning sounds. Free AVAS software update at franchised Mercedes-Benz dealers.

What's wrong?

The Acoustic Vehicle Alerting System is the outside sound system on these 2022-2025 Mercedes-Benz vehicles. Electric and hybrid vehicles are quiet at low speeds, so the system plays an external pedestrian alert while the vehicle reverses. That sound helps people nearby recognize that the vehicle is moving.

On affected vehicles, the sound generator software can play the wrong type of reverse warning sound. Mercedes-Benz says the installed software can make a noise tone instead of the beep tone intended for vehicles of the same make, model, model year, body type, and trim. The sound can still meet volume specifications, but the tone does not match the required setup for the vehicle.

The driver does not receive a warning sign before this noncompliance. The issue is in the outside alert sound, so an owner is unlikely to notice it from the driver's seat during normal driving.

Who's affected?

Scope spans Eqs, Eqe, AMG, Maybach, and S 580 E variants across 2022-2025, all tied to the external pedestrian alert sound generator.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.

What's the safety risk?

An incorrect AVAS sound can fail to alert pedestrians that the vehicle is reversing, which raises crash risk. The driver gets no warning from the vehicle, so confirm whether your VIN is included and schedule the software update soon. Repair is free at any franchised Mercedes-Benz dealer.

What should I do?

1. Check your VIN to confirm your 2022-2025 Mercedes-Benz vehicle is included in this recall.
2. Contact a franchised Mercedes-Benz dealer to schedule the free AVAS software update that corrects the external pedestrian warning sound while reversing.
3. Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 25V366 when you call.
4. Use extra care when backing up until the repair is complete, since the incorrect warning sound can fail to alert pedestrians.

What happens at the repair

At the dealer, a Mercedes-Benz technician installs updated AVAS software so the Acoustic Vehicle Alerting System uses the correct external pedestrian warning sound while reversing. The software update and labor are free under the recall. Out-of-pocket repairs already paid are handled through the existing new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
