Mercedes-Benz filed this with NHTSA as an over-the-air update dated May 4, 2024, received May 30, 2024, about the electrical system — 1 document under this number: OTA - 20240503. It names 71 model years across Mercedes-Benz and Mercedes-Maybach (2021–2025).

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz 24P5497723 a recall?
No. A over-the-air update is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.

A over-the-air update is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 24P5497723 cover?
The manufacturer filed it against 71 model years across 2 brands (Mercedes-Benz and Mercedes-Maybach): 2024 Mercedes-Benz AMG GT, 2023 Mercedes-Benz AMG GT, 2022 Mercedes-Benz AMG GT, 2021 Mercedes-Benz AMG GT, 2024 Mercedes-Benz C-Class, 2023 Mercedes-Benz C-Class and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
