Mercedes-Maybach bulletin OTA - 5497746
Mercedes-Maybach filed this with NHTSA as a over-the-air update dated Mar 7, 2025, received Mar 17, 2025, about the electrical system. It names 2 model years (2020). A over-the-air update 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.

A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.
