Summary
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY22-24 C-Class, AMG GT, AMG SL (206, 192, 232 platform) vehicles, the electric engine mount control unit software does not correspond to the latest series production configuration. In this case, a short circuit may be incorrectly detected, and the engine mounts can de-energize. This in turn could lead to changes in the vehicle’s dynamics and noise complaints from the customer. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the electric engine mount control unit software.

Owners of these vehicles have filed 23 complaints in the electrical category.
