Official summary
Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain 2024 C-Class, E-Class, and GLC (206, 214, 254 platform) vehicles, the electronic ignition lock control unit does not correspond to current specifications. As a result, the ignition lock may not react after a key cycle, which could result in the vehicle not starting and the instrument cluster display not reacting. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the electronic ignition lock 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.
