Mercedes-Benz has issued a safety recall for certain 2021-2023 S-Class and Maybach S-Class models due to potential engine control unit software issues that could lead to engine stalls or increased exhaust temperatures. The recall affects 27,190 vehicles in the United States.
The software error could cause the engine to stall during a CAMTRONIC system failure, which controls variable valve lift. Additionally, the incorrect programming could lead to increased exhaust temperatures due to excessive fuel delivery, potentially damaging engine components.
Mercedes-Benz became aware of the issue after receiving an increase in warranty claims and reports of engine non-start conditions, loss of propulsion, and illuminated check engine lights. An investigation revealed a software error in the lambda control system.
The recall involves updating the engine control unit software to correct the programming errors. Mercedes-Benz has not reported any injuries or deaths related to the issue. Mercedes-Benz AG has issued a recall for certain S-Class models to address a software issue in the engine control unit.
Affected owners will be notified by November 26, 2024, and the update will be provided at no cost. The recall condition has been fixed in production since September 20, 2023. The S 580, S 580e, and S 500 are all powered by inline-six engines with mild hybrid assistance. The S 580e, despite being less powerful than the S 580, is surprisingly slower to 60 mph.
The Maybach S-Class offers even more luxury and performance, with the top of the line S 680 featuring a V12 engine. The AMG S 63 E PERFORMANCE is the most powerful S-Class model, combining a V8 engine with a rear-mounted electric motor for a total output of 791 horsepower.
