## NHTSA's summary

Mercedes\-Benz AG, the manufacturer of Mercedes\-Benz vehicles, has determined that on certain subject vehicles, the powertrain control unit software does not correspond to current production specifications. Consequently, there is a risk that the 48V battery may not charge due to an implausible state\-of\-charge in the powertrain control unit. MBUSA will conduct a service campaign. An authorized Mercedes\-Benz dealer will update the powertrain control unit software.
