## NHTSA's summary

Mercedes\-Benz AG, the manufacturer of Mercedes\-Benz vehicles, has determined that on certain subject vehicles, the battery management system control unit software may not correspond to current production specifications. Consequently, there is risk of a no\-start condition after a bus idle with a corresponding battery malfunction message in the instrument cluster, reduced power from the electric drive unit, or reduced charging power under certain conditions. MBUSA will conduct a service campaign. An authorized Mercedes\-Benz dealer will update the battery management system control unit software.
