What's wrong?
The engine control unit software in the 2021-2023 Mercedes-Benz S 580 is the program that tells the engine how to manage fuel, ignition, emissions controls, and cylinder deactivation. On these vehicles, that software also works with the Camtronic system, which switches some cylinders off during certain driving conditions to improve efficiency. Lambda control is the part of the software logic that adjusts the air-fuel mixture.
The problem starts only if the Camtronic hardware has a mechanical failure while cylinder deactivation is engaged. In that situation, the software does not turn off lambda control as designed. The engine then receives the wrong control response, which can make it overheat, stall, lose propulsion, or refuse to restart.
There is no warning sign before failure. Once the failure is happening, the driver can see a Check Engine Light or experience a sudden loss of propulsion or a no-start condition.

What's the safety risk?
An engine stall increases crash risk because the vehicle can lose power while moving. An overheating engine also increases fire risk. There is no warning sign before the failure, so schedule the ECU software update soon and stop safely if the engine stalls or overheats. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2021-2023 Mercedes-Benz S 580 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free ECU software update that corrects the engine-stall and overheating risk.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 24V704 when you call.
- Stop driving and call the dealer if the engine overheats, stalls, or shows an engine warning before your appointment.
What happens at the repair
At the dealer, a Mercedes-Benz technician updates the ECU software to address the recalled engine overheat or stall condition tied to a Camtronic mechanical failure. The software update is free under the recall, and parts and labor are covered. 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. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
