What's wrong?
The electric drivetrain software in these 2022-2023 Mercedes-Benz AMG Eqs, AMG Eqe, Eqs 580, Eqs 450, EQS580, and EQS450 vehicles manages how the electric drive responds while the vehicle is moving. It monitors faults in the propulsion system and tells the drive unit how to react, including when to reduce power or keep propulsion available.
On affected vehicles, the software can respond incorrectly when it detects a fault at a specific plug connector inside the electric drive. The problem comes from fault management logic in the software, not from normal wear by the driver. If that response happens while driving, the vehicle can lose drive power, which means the accelerator no longer delivers propulsion as expected.
The driver does not receive a warning before the issue occurs because of the way the failure happens. There is no warning sign before failure.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific sedan.
What's the safety risk?
A loss of drive power raises crash risk because the vehicle can slow or stop responding while traffic around you continues moving. There is no warning sign before this failure. If power drops, move out of traffic when safe and call the dealer for service. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2022-2023 Mercedes-Benz AMG Eqs, AMG Eqe, Eqs 580, Eqs 450, EQS580, or EQS450 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free electric drivetrain software update that addresses the loss-of-drive-power defect.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 23V405 when you call.
- Avoid unnecessary trips until the software update is complete.
What happens at the repair
At the dealer, a Mercedes-Benz technician updates the electric drivetrain software that controls drive power delivery. The software update and labor are free under the recall, and the repair is available through a Mercedes-Benz dealer. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain under warranty. If you have prior paperwork for a related drivetrain software repair, ask the service desk how warranty coverage applies.
