Official summary
Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2023 2024 C-Class (206 platform) and GLC (254 platform) vehicles, the door control unit software does not correspond to current production specifications. In this case, the 12V starter battery may sporadically discharge. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the door control unit software.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
