Mercedes-Maybach service campaign NCU - 2025030013
Mercedes-Maybach filed this with NHTSA as a service campaign dated Mar 28, 2025, received Apr 1, 2025, about the power train. It names 2 model years (2023). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationMercedes-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.
